Abstract and Figures

Peripheral nerve injury (PNI) is an incapacitating situation and has no effective therapy until now. We examined the possible role of crude leaves of Moringa oleifera Lam. at 200 mg/kg body weight in accelerating the functional regain in the sciatic nerve lesion induced mouse model (Adult male albino mice (BALB/c). Motor functions were evaluated by using the sciatic functional index, muscle mass, and muscle grip strength measurement, whereas the sensory functions were evaluated by using the hot plate test. Blood glucose levels and blood cell composition were also analyzed. We found that the Moringa oleifera crude leaves endorse the sensory and motor functions reclamation following the PNI with a statistically significant difference (p < .05). It also revitalizes the gastrocnemius muscle by mass restoration with glycemic management perspective. Conclusively, the crude powder of Moringa oleifera leaves exhibited a function restoration boosting property and further detailed studies for its application as a therapeutic agent are strongly recommended.

Abstract
Peripheral nerve injury (PNI) is an incapacitating situation and has no effective ther-
apy until now. We examined the possible role of crude leaves of Moringa oleifera Lam .
at 200 mg/kg body weight in accelerating the functional regain in the sciatic nerve
lesion induced mouse model (Adult male albino mice (BALB/c). Motor functions were
evaluated by using the sciatic functional index, muscle mass, and muscle grip strength
measurement, whereas the sensory functions were evaluated by using the hot plate
test. Blood glucose levels and blood cell composition were also analyzed. We found
that the Moringa oleifera crude leaves endorse the sensory and motor functions rec-
lamation following the PNI with a statistically significant difference (p < .05). It also
revitalizes the gastrocnemius muscle by mass restoration with glycemic management
perspective. Conclusively, the crude powder of Moringa oleifera leaves exhibited a
function restoration boosting property and further detailed studies for its applica-
tion as a therapeutic agent are strongly recommended.

1 | INTRODUCTION
Peripheral nerve injuries (PNIs) is ver y common and complex and
impeding health fac tor in our society and remains incurable up to
now. It may result from road traffic accidents, sharp lacerations,
gunshot wounds, and various other physical traumas. Consequently,
the affected nerves undergo an intricate pathological sequence and
associated compromised sensor y and motor functions. Though the
peripheral nervous system is capable to exhibit a regenerative ca-
pability following the PNI, this phenomenon is quite slow and the
impending muscular atrophy exacerbates the situation before the
targeted organs’ re-innervation (Aziz et al., 2019; Imran et al., 2019;
Rasul et al., 2019) Despite incredible treatment approaches, com-
plete functional retrieval still remains as a challenge to be resolved.
The sluggish regeneration rates and the threatening muscular atro-
phy are the primary limitations in developing any novel therapeutic
interventions against PNI. In order to cope with this need, scientists
are exploring effective and affordable remedies to accelerate func-
tional reclamation and endorse axonal regeneration (Hussain, Rasul,
et al., 2018; Hussain, Zhang, et al., 2018). Meanwhile, plants and
plant-derived compounds are getting more consideration because
of their health-promoting properties (Hussain et al., 2019; Hussain,
Rasul, et al., 2018; Hussain, Zhang, et al., 2018), as naturally occur-
ring compounds present auspicious substitute therapeutic strategies
for affected individuals.
Medicinal plants and herbs are a source of a plethora of phy-
tochemic als that are demonstrated to be beneficial and ef fective
in preventing, treating or improving different diseases and health
conditions. Moringa oleifera Lam. (M. oleifera) is one of the richest
sources of vitamins and minerals from the Moringaceae family.
Moringa has been widely utilized as folk medicine owing to its rich
phytochemistry with special reference to various phytoconstituents
such as alkaloids, saponins, tannins, steroids, phenolic acids, glu-
cosinolates, flavonoids, and terpenes. However, the presence of
phenolic acids, glucosinolates, and flavonoids are responsible for
its anticancer, neuroprotective, and antioxidant potential through
various mechanistic routes. It is a native plant of some regions of
the Himalayan mountains found in northwest Pakistan and India
(Fahey, 2005). The extracts from M. oleifera evince various nu-
traceutical and pharmacological properties such as anti-oxidant,
anti-cancerous, anti-inflammatory, and neuroprotective and have
been traditionally found to be a promising drug for various dis-
orders such as cancer and liver diseases (Abdull Razis, Ibrahim,
& Kntay ya, 2014; Kooltheat et al., 2014). Interestingly, it miti-
gates memory impairment, age-related dementia, neurodegen-
eration, Parkinson's disease, and Alzheimer's disease (Ganguly
& Guha, 20 08; Sutalangka, Wattanathorn, Muchimapura, &
Thukham-mee, 2013). Moreover, M. oleifera exhibits neurotrophic
and neuroprotective properties as its leave extract stimulates and
promotes neuronal outgrow th and survival both under normal toxic
cond iti ons (Han nan et al. , 2014 ). Howe ve r, the ev ide nce con cer nin g
the effects of M. oleifera leaves in crude or extract forms on the
nerve regeneration after an injury is scarce until now. Therefore,
this study aimed to evaluate the potential role of crude leaf pow-
der of M. oleifera in promoting the motor and sensor y functions re-
trieval following a mechanically induced injury to the Sciatic nerve
in a mouse model.
2 | MATERIALS AND METHODS
2.1 | Animals and study design for the experiment
Adult male albino mice (BALB/c) (n = 10) of th e same weig ht (3 0 ± 4 g)
and age (5–6 weeks) were provided by the department of physiolog y
(Government College University Faisalabad). The mice were sepa-
rated into two groups (Control group n = 5, Treatment group n = 5).
All mice were given standard conditions of living with ad libitum
food and water. They were housed in separate rodent plastic cages
at ambient temperature and light/dark cycle as (24 ± 2°C; dark/light
cycle). The study was approved by the Institutional Animal C are and
Ethics Committee (ERC 254).
2.2 | Plant collection and preparation
The leaves of M. oleifera were purchased from the local market of
Faisalabad and identified by the botanist from the Department of
Botany, Government College University Faisalabad. The leaves
were shade dried and ground into powder as already described
(Priyadarshani & Varma, 2014). Then, leaves powder was mixed in
the normal chow diet of treatment group mice at the dose given in
the literature as 200 mg/kg of body weight. The mice were given the
privilege to consume an average diet intake of 5 g/animal; required
to produce the biological effect according to the dose of M. oleifera.
The average weight, drink, and food intake were measured through-
out the period of the experiment (pre and post to the sciatic nerve
injury) by adapting the standard procedures.
2.3 | Sciatic nerve compression injury
The mice were subjected to the nerve crush after the acclimatiza-
tion of one weak. For the purpose, they were anesthetized through
intraperitoneal injection of ketamine (100 mg/kg BW) and xylazine
(5 mg/kg BW) mixture (Ma et al., 2013). The incision site was shaved
smoothly, and a fine cut over an extent of 2 cm along the proximal
half of the fleck between the trochanter major and the knee joint
was induced. The sciatic nerve was compressed (constant pressure)
for 15 s by using a pair of forceps. It was made sure by visual obser-
vation that the nerve was perfectly compressed and the epineurium
remained intact. Then, skin suturing was done (4-0 stitches) and mice
were permitted to recover (Halter et al., 2010; Hussain et al., 2013;
Imran et al., 2019). After the induction of injury, mice were divided
into two groups; the control group (n = 7) and the treatment group
(n = 7).

2.4 | Behavioral analysis
2.4.1 | Sciatic functional index
On all mice, walking track analysis was performed throughout the
study as three times prior to surger y and then every third day after
surgery. The plantar surface of mice was painted with the non-
toxic ink and they were allowed to walk along the wooden track
(50 cm × 7 cm). Approximately, five notable footprints were taken
and the sciatic functional index (SFI) was measured with the follow-
ing formula.
In the above formula, the distance between 1st and 5th toe is toe
spread (TS), Print length (PL) is the distance from the top of the 3rd
toe to heel, and the distance between 2nd and 4th toe is intermedi-
ary toe spread (IT ) (Navarro, 2016).
2.4.2 | Muscle grip strength
Muscle grip strength measurement is an optimal parameter while
assessing the motor functional recovery following the sciatic
nerve lesion. It allows encountering the in vivo muscle strength
force of mice and associated ner ve regeneration capabilit y as
motor functions rehabilitation is indirectly associated with the
rate of nerve regeneration. An average value of three readings
was recorded by using muscle grip strength meter (Bioseb) for
both hind limbs (Ipsilateral and contralateral). The results of the
control and treatment group were compared with ensure the
functional recovery.
2.4.3 | Thermal withdrawal threshold (hot plate
test)
The regain of sensory functions was evaluated by using the ther-
mal th re sho ld with the hot pl at e ap par at us (SCI LO GE X MS7-H550 -S
LED di git a l 7 × 7 Hot pla te st irr e rs). Th e hot plat e tes t was pe r fo r med
by following the procedure as given previously (Aziz et al., 2019). In
brie f, the mouse wa s ad apted to the non fu nct ionin g ho t plate dev ic e
for one mi nu te before the actu al exp eri me nt . The n, each mou se was
adjusted in such a way that their operated hind paws were exposed
to the hot sur face of th e funct ionin g ho t plate device (56 ± 2° C) . The
mouse was observed to elicit any response of jerk or lick in result
to the thermal stimuli and this time was recorded as the hot plate
latency. An average of three readings was taken as a final reading.
Following such a response, the mouse was immediately removed
from the device to aver t any pathological intervention to the organ
tissues.
2.4.4 | Muscle weight
The gastrocnemius muscle mass was measured in order to explore
the extent of muscle atrophy as it is one of the most significant con-
tributors in delaying the functional escalation. Following the mus-
cle harvesting, the muscle mass of both groups (Ipsilateral legs) as
normal chow group and M. oleifera chow group were measured and
compared (Li et al., 2013; Tuffaha et al., 2016).
2.4.5 | Random blood glucose
Random blood glucose was measured in order to assess the con-
tribution of glucose levels in exacerbating the pathological condi-
tion following the sciatic nerve injur y. As a higher level of blood
glucose initiates metabolism-related pathological pathways at
the site of PNI. A glucometer (Accu-chek) was used to assess the
blood glucose levels in both groups at different time intervals in
the study according to the given procedure of (Asmat, Abad, &
Ismail, 2016).
2.5 | Blood cells composition analysis
The blood cell composition was measured by a hematological ana-
lyzer to evaluate the levels of various blood cell count either altered
by the PNI or improved by the M. oleifera treatment.
3 | RESULTS
3.1 | Effect of M. oleifera on body weight and food
intake
Body weight and food intake were measured in both groups, that
is, normal chow group and M. oleifera chow group (Figure 1a,b)
throughout the period of the experiment (pre and post to the sciatic
nerve injury). We observed no statistical change (p = .461) in the
diet intake and body mass in both groups even after the addition of
M. oleifera in the mice diet and sciatic nerve le sion induction. Hence,
it is speculated that M. oleifera did not modif y the taste of diet and
hence not hampered the diet intake.
3.2 | Effect of M. oleifera on motor functions
retrieval (SFI & Grip strength)
Following the sciatic nerve injury, there is a complete functional
loss of motor neurons. Functional retrieval is directly connected to
the rate of ner ve regeneration, which is usually slow under ordinar y
situations. The SFI and Grip strength (% of initial force) were meas-
ured to evaluate the motor functional recovery. We found an early
motor function recover y in the M. oleifera chow group (Figure 2a,b)

with statistically significant differences (p < .05). Furthermore, the
development of muscle atrophy is noteworthy, as shown by the de-
creased muscle mass, in normal chow group indicates the muscle
denervation, whereas the muscle mass of Gastrocnemius muscle
was recovered significantly in the M. oleifera chow grou p (F ig ure 2c).
3.3 | Effect of M. oleifera on sensory
functions retrieval
Following the sciatic ner ve injury, both motor and sensory func-
tions are compromised since the sciatic nerve is a mixed type of
nerve. Therefore, measuring the sensory function is also equally
important. The sensory function retrieval following the sciatic
nerve lesion was evaluated by using the hot plate test (Figure 3).
In the hot plate test, the paw withdrawal latency is indicative of
nociception ac tivit y (Ra su l et al ., 2019). We fo un d a n early highly
significant paw withdrawal response (p < .001), which shows
sensor y functions recovery, in the M. oleifera chow group. This
ultimately indicates the effectiveness of M. oleifera in acceler-
ating the rate of nociceptive activity retrieval after the sciatic
nerve lesion.
3.4 | Effect of M. oleifera on random blood
glucose and blood cell measurement
The peripheral ner ve function is affected by higher levels of blood
glucose as deranged glucose metabolism initiates many pathological
sequelae at the site of PNI. Therefore, measuring blood glucose levels
is very effective while assessing the functional reclamation following
the sciatic nerve injury (Nascimento, Pupe, & Cavalcanti, 2016). We
found that random blood glucose levels were significantly reduced
(p < .05 ) in the M. oleifera chow grou p (Figu re 4a). M. oleifera has been
previously found to enhance the platelet count, and here, we found
that platelet level was also up-regulated, though the result s were
not significant (Figure 4b). This might indicate the attenuation of an
underlying pathological pathway of nerve injur y, and thereby, it ac-
celerates its regeneration.
4 | DISCUSSION
This study was considered to inspec t the possible role of M. oleifera
as a novel agent in accelerating the ner ve regeneration rate and as-
sociated functions regain in a mouse model of PNI. We observed

that body mass and food intake were not altered in response to the
addition of M. oleifera and induction of sciatic nerve lesion through-
out the experiment. Moreover, we found that M. oleifera has the
capability of promoting the motor and sensor y functional recover y
after the induction of sciatic nerve lesion to the mice. Based upon
the severity and nature of the ner ve injury, sensory and motor func-
tions might compromise partially or completely. As the functional
reclamation is directly associated with the nerve regeneration rate
which is usually quite sluggish under conventional conditions. Here,
we reported that M. oleifera causes an early reclamation of sensory
and motor func tions as shown in results with significant differences.
The motor functions were found to be significant as measured by
SFI (p = **.029) and grip strength (p = **.002). Whereas, the sensory
functions, as measured by hot plate test (p = ***.000), were found to
be retrieved earlier in the M. oleifera chow group. Fur thermore, poor
communication of the muscle due to the absence of basal stimuli
causes the target muscle to undergo muscle atrophy. This phenom-
enon possesses additional burden at the site of nerve injury and
thereby further decreasing the chances of functional retrieval (dos
Santos et al., 2016). Meanwhile, the muscle atrophy also causes an
additional delay in the regeneration of injured neurons as it halts the
production of trophic factors and associated poor functional recov-
ery (Li et al., 2013; Navarro, 2016; Tuffaha et al., 2016). Here, we

found that the muscle atrophy in gastrocnemius muscle mass was
reserved with a significant dif ference in the M. oleifera chow group
(p = . *04) following the sciatic nerve injury. Taken altogether, these
findings suggest that M. oleifera can accelerate the rate of function
regain following an injury to the peripheral nervous system as well
and these findings concomitantly endorse the already reported
data regarding its benefits for the central nervous system (Singh &
Navneet, 2018). It is already well documented by recent investiga-
tions that the neuronal dysfunctions and neurodegeneration could
be improved by flavonoids intervention (Hussain, Rasul, et al., 2018;
Hussain, Zhang, et al., 2018), we assume that the function promoting
effects of M. oleifera might be attributed to the flavonoid class, but
that requires fur ther investigation.
Furthermore, in our study, we established that M. oleifera ex-
hibits glucose-lowering effects, which might be attributed to the
anti-diabetic effects of M. oleifera already reported (Patel, Ayaz, &
Parikh, 2015). Thus, we hypothesize here that different phytochem-
icals in the M. oleifera modify the glucose metabolism machiner y at
cellular levels which eventually recovers the rate of nerve regenera-
tion. Meanwhile, the higher levels of blood glucose cause additional
pathological features at the PNI site by disturbing the physiological
glucose metabolism and also imitates several pathological features
[29]. Similarly, the hyperglycemic induces oxidative stress which is a
well-known factor as a dynamic power for the initiation of frequent
clinical problems. This balance of anti-oxidative and oxidative stress
is very much sensitive to the glucose level since the minor elevated
glucose level affects the entire oxidative system of the biological
system. Here in PNI, this oxidative stress might serve as a key regula-
tor in delaying functional retrieval (Asmat et al., 2016; Latini, Pereira,
Couture, Campos, & Talbot, 2019; Menon et al., 2004), which could
be overcome by the addition of M. oleifera extract in the diet. In this
scenario, M. oleifera leaves cont ain flavonoids, such as quercetin and
kaempferol, as the most potent antioxidant s as well (Hussain, Rasul,
et al., 2018; Hussain, Zhang, et al., 2018).
5 | CONCLUSION
To sum up, this study provides evidence of the effectiveness of the
Moringa leaves in the crude form against traumatic nerve injury.
Based on the present findings and previous data, it can be suggested
that this plant can prove an interesting and valuable target for the
discovery of effective and affordable intervention against periph-
eral nerve injuries. Moreover, this study shows that oral administra-
tion of crude of M. oleifera does not affect the eating behavior as
the body weight and eating pattern remained unmodified. Although
these preliminary results are impregnated with positivity, however
the further investigations to identify the actual bioactive constitu-
ent and its characterization is strongly recommended alongside
the long-term human-based clinical trials ought to be conducted
to apprehend the impac t of these bioactive moieties and their pos-
sible mechanistic concerns in actual setting and their commercial
adaptations.

Abstract The mandate of the current investigation was to elucidate the therapeutic and antioxidant perspective of black tea. Purposely, black tea compositional analysis followed by polyphenol extraction and antioxidant characterization was done. Moreover, the theaflavin from black tea extract was also isolated through the solvent partition method. Lastly, the neuroprotective effect of isolated theaflavin was assessed through a bio‐efficacy trial. The outcomes delineated that black tea showed promising nutritional composition with special reference to protein and fiber. Among the extraction solvent, ethanol performed better as compared to methanol and water likewise, higher extraction was noticed at 60 min followed by 90 and 30 min. All the extracts indicated antioxidant activity reflected through significant DPPH, TPC, FRAP, and beta carotene as‐69.13 ± 3.00, 1148.92 ± 14.01, 752.44 ± 10.30, and 65.74 ± 3.28, respectively. However, isolated theaflavin exhibited higher antioxidant capacity as‐737.74 ± 12.55, 82.60 ± 2.33, and 853.77 ± 9.55, for TPC, DPPH, and FRAP, respectively, as compared to extracts. In 15 days' efficacy was physically induced with sciatic nerve injury h sciatic nerve injury physically and treated with isolated theaflavin. A total of 12 healthy albino mice were randomly assigned to either the control (n = 6) or theaflavin (5.0 mg/kg (n = 6)) groups.

Diabetic peripheral neuropathy is one of the most prevalent complications of diabetes mellitus. It is the most common type of neuropathy characterized by decreased sensory functions in the lower extremities and substantial neuropathic pain. Based on clinical characterization, it is classified into symmetric and asymmetric neuropathy. The pathological changes and neuronal function impairment during diabetes are associated with various pathways, including polyol pathway activation, advanced glycation end-products formation, oxidative stress, protein kinase C activation, poly ADP-ribose polymerase, and hexosamine pathways. Demyelination, axonal atrophy, nerve fibre loss, reduced regeneration, and loss of neurovascular interactions are hallmarks. Although some symptomatic and supportive therapies, such as tricyclic agents, antiarrhythmics, opioid analgesics, incretin, aldose reductase, and protein kinase C inhibitors, are in practice, the outcome is not promising. To fill this gap, natural product-based therapy can prove prodigious as an effective alternative. This review aims to comprehend the available literature on the role of various biological molecules in ameliorating diabetic peripheral neuropathy. These molecules play a key role in reducing oxidative-nitrosative stress, aldose reductase activity, and neuronal apoptosis. They control glucose and HbA1c% levels and improve nerve conduction velocity, axonal regeneration, and antioxidant species (catalase, superoxide dismutase, malondialdehyde). They are known for their attenuating thermal and mechanical hyperalgesia and tactile allodynia. Therefore, there is a need to evaluate these molecules at the pre-clinical and clinical levels for efficacy. Hence, natural molecules may act as promising players against diabetic peripheral neuropathy and are a ray of hope for suffering individuals.

An edible coating was developed using gelatin extracted from the skin of gray triggerfish (Balistes capriscus) and applied to the fillet of the smooth‐hound shark (Mustelus mustelus). Moringa oleifera leaf extract was added to gelatin coating solution to improve its preservative properties. The phenolic profiles and antioxidant and antibacterial activities of M. oleifera extracts were determined. Phenolic acids constituted the largest group representing more than 77% of the total compounds identified in the ethanol/water (MOE/W) extract, among which the quinic acid was found to be the major one (31.48 mg/g extract). The MOE/W extract presented the highest DPPH• scavenging activity (IC50 = 0.53 ± 0.02 mg/ml) and reducing (Fe3+) power (EC0.5 = 0.57 ± 0.02 mg/ml), as well as interesting inhibition zones (20–35 mm) for the most tested strains. Coating by 3% of gelatin solution significantly reduced most deterioration indices during chilled storage, such as malondialdehyde (MDA), total volatile basic nitrogen (TVB‐N), weight loss, pH, and mesophilic, psychrophilic, lactic, and H2S‐producing bacterial counts. Interestingly, coating with gelatin solution containing MOE/W extract at 20 μg/ml was more effective than gelatin applied alone. Compared with the uncoated sample, gelatin‐MOE/W coating reduced the weight loss and MDA content by 26% and 70% after 6 days of storage, respectively. Texture analysis showed that the strength of uncoated fillet increased by 46%, while the strength of fillet coated with gelatin‐MOE/W only increased by 12% after 6 days of storage. Fish fillet coated with gelatin‐MOE/W had the highest sensory scores in terms of odor, color, and overall acceptability throughout the study period. Quinic acid was found to be the major compound in the ethanol/water Moringa extract gelatin coating enriched with Moringa extract contributed to delay its deterioration

Peripheral nerve injury (PNI) is an incapacitating situation and has no effective therapy until now. We examined the possible role of crude leaves of Moringa oleifera Lam. at 200 mg/kg body weight in accelerating the functional regain in the sciatic nerve lesion induced mouse model (Adult male albino mice (BALB/c). Motor functions were evaluated by using the sciatic functional index, muscle mass, and muscle grip strength measurement, whereas the sensory functions were evaluated by using the hot plate test. Blood glucose levels and blood cell composition were also analyzed. We found that the Moringa oleifera crude leaves endorse the sensory and motor functions reclamation following the PNI with a statistically significant difference (p < .05). It also revitalizes the gastrocnemius muscle by mass restoration with glycemic management perspective. Conclusively, the crude powder of Moringa oleifera leaves exhibited a function restoration boosting property and further detailed studies for its application as a therapeutic agent are strongly recommended.

Peripheral nerve injury is one of the major health concerns of the present era which can lead to the long‐lasting disability and even demise. Currently, no effective and side effect free remedy exists and exploration of effective therapeutic strategies to regain functional outcome is a need of hour. In the present study, we used BALB/c mice (N = 14 age, 10–12 weeks & weight 32–34 g) that were divided into two groups: Normal chow (n = 7) and Fennel chow (n = 7) group. Here, we have explored the role of crude Foeniculum vulgare mill seeds in promoting functional recovery following a mechanical insult to the sciatic nerve by an oral administration of a crude dose of 500 mg/kg BW. The recovery of both sensory and motor functions was significantly (p > .05) accelerated in the treatment group, assessed by behavioral analyses alongside total antioxidant capacity increase. Conclusively, F. vulgare can be a potential therapeutic candidate for accelerating functional recovery after peripheral nerve injury. Practical applications The outcomes of study have vital practical application both for scientists and consumers. The therapeutic role of phytochemicals on functional recovery has not been explored yet. This study will help figure out plant based regimen as booster for brain health and intervention against traumatic nerve injuries. Moreover, it may also attract the food and pharmaceutical industries to formulate cost effective therapeutic products. Likewise, it can prove instrumental for scientists for advance research on this aspect with more mechanistic targets.

Peripheral nerve injury is a complex condition which results in restricted physical activity. Despite the tremendous efforts to figure out effective remedies, the complete functional retrieval is still a goal to be achieved. So, the need of hour is the exploration of potential natural compounds to recover this functional loss. Here, we have investigated the role of a local plant "Neurada procumbens" in ameliorating the functional recovery after an induced nerve compression injury in a mouse model. A dose of N. procumbens (50mg/kg of body weight) was administered orally from the day of injury to onwards. The motor functional recovery was assessed by evaluating muscle grip strength and sciatic functional index; while the sensory functions were gauged by the hotplate test. The serological parameters were carried out to analyze the effect of N. procumbens on oxidative stress level. The recovery of sensory and motor functions was significantly improved and perceived earlier in the treatment group. Moreover, the elevated antioxidant level was statistically significant in the treatment group. These results indicate that the supplementation of N. procumbens accelerates functional recovery after sciatic nerve crush injury.

Neurodegenerative and neuropsychiatric diseases are characterized by the structural and functional abnormalities of neurons in certain regions of the brain. These abnormalities, which can result in progressive neuronal degeneration and functional disability, are incurable to date. Although comprehensive efforts have been made to figure out effective therapies against these diseases, partial success has been achieved and complete functional recovery is still not a reality. At present, plants and plant-derived compounds are getting more attention because of a plethora of pharmacological properties, and they are proving to be a better and safer target as therapeutic interventions. This review aims to highlight the roles of tannins, ‘the polyphenol phytochemicals’, in tackling neurodegenerative diseases including Alzheimer’s and Parkinson’s diseases as well as neuropsychiatric disorders like depression. Among the multifarious pharmacological properties of tannins, anti-oxidative, anti-inflammatory, and anti-cholinesterase activities are emphasized more in terms of neuroprotection. The current review also throws light on mechanistic pathways by which various classes of tannins execute neuroprotective effects. Despite their beneficial properties, some harmful effects of tannins have also been elaborated.

Peripheral nerve injury is a common condition with a multitude of signs and symptoms. The major consequence of injury is limited physical activity. Presently, we are lacking effective therapies for PNI and it is need of the hour is to explore potential remedies for the recovery of functional loss. Here, we have investigated the role of crude Cannabis sativa L. leaf powder in promoting functions recovery, in mouse model subjected to a traumatic sciatic nerve injury. A dose of 200mg/kg of the body weight per day was administered orally from the day of nerve crush till the end of the experiment. The motor functions were evaluated by measuring sciatic functional index, muscle grip strength and muscle mass; whereas the sensory functions were assessed by hotplate test. The haematology and serum analyses were carried out to estimate the effect of treatment on the systemic index and oxidative stress. The gain of motor functions was significantly improved and was early noticed in the treated mice. Restoration of muscle mass and elevated haemoglobin level were statistically significant in the treatment group. This study indicates that Cannabis sativa L. supplementation accelerates the motor functions recovery after nerve compression injury.

Neurodegeneration is a progressive loss of neuronal cells in certain regions of the brain. Most of the neurodegenerative disorders (NDDs) share the communal characteristic such as damage or reduction of various cell types typically including astrocytes and microglial activity. Several compounds are being trialed to treat NDDs but they possess solitary symptomatic advantages along with copious side effects. The finding of more enthralling and captivating compounds to suspend and standstill the pathology of NDDs will be considered as a hallmark of present times. Phytochemicals possess the potential to alternate the synthetic line of therapy against NDDs. The present review explores the potential efficacy of plant-derived flavonoids against most common NDDs including Alzheimer's disease (AD) and Parkinson's disease (PD). Flavonoids are biologically active phytochemicals which possess potential pharmacological effects, including antiviral, anti-allergic, antiplatelet, anti-inflammatory, anti-tumor, anti-apoptotic and anti-oxidant effects and are able to attenuate the pathology of various NDDs through down-regulating the nitric oxide (NO) production, by reducing the tumor necrosis factor-α (TNF-α), by reducing the excitotoxicity of superoxide as well as acting as tyrosine kinase (TK) and monoamine oxidase (MAO) inhibiting enzyme.

Neurodegenerative diseases are conventionally demarcated as disorders with selective loss of neurons. Conventional as well as newer molecules have been tested but they offer just symptomatic advantages along with abundant side effects. The discovery of more compelling molecules that can halt the pathology of these diseases will be considered as a miracle of present time. Several synthetic compounds are available but they may cause several other health issues. Therefore, natural molecules from the plants and other sources are being discovered to replace available medicines. In conventional medicational therapies, several plants have been reported to bestow remedial effects. Phytochemicals from medicinal plants can provide a better and safer alternative to synthetic molecules. Many phytochemicals have been identified that cure the human body from a number of diseases. The present article reviews the potential efficacy of plant-derived alkaloids, which possess potential therapeutic effects against several NDDs including Alzheimer's disease (AD), Huntington disease (HD), Parkinson's disease (PD), Epilepsy, Schizophrenia, and stroke. Alkaloids include isoquinoline, indole, pyrroloindole, oxindole, piperidine, pyridine, aporphine, vinca, β-carboline, methylxanthene, lycopodium, and erythrine byproducts. Alkaloids constitute positive roles in ameliorating pathophysiology of these illnesses by functioning as muscarinic and adenosine receptors agonists, anti-oxidant, anti-amyloid and MAO inhibitors, acetylcholinestrase and butyrylcholinesterase inhibitor, inhibitor of α-synuclein aggregation, dopaminergic and nicotine agonist, and NMDA antagonist.

BACKGROUND AND OBJECTIVES: Diabetic neuropathy is a major cause of neuropathy worldwide and may lead to amputations and incapacity. This study aimed at a detailed and updated review on diabetic neuropathy, focusing on its classification, diagnostic investigation and treatment. CONTENTS: It is estimated that 371 million people aged from 20 to 79 years, worldwide, have diabetes mellitus and that at least half of them are unware of the diagnosis. Its prevalence in Central and South America was estimated in 26.4 million people, corresponding to approximately 6.5% of the population. Among microvascular complications, diabetic neuropathy is the most prevalent, leading to the highest rates of hospitalization, atraumatic amputations and incapacity. Diabetic neuropathy may have different clinical presentations, being distal symmetric polyneuropathy its most frequent presentation and major mechanism to the development of diabetic foot. Predominantly it presents with positive (burning, tingling) and negative (numbness, loss of sensitivity) sensory symptoms. In general it is associated to autonomic signs and symptoms and seldom there is motor manifestation. Approximately 20% of patients with distal symmetric polyneuropathy have neuropathic pain, which sometimes becomes chronic and disabling. CONCLUSION: Early and accurate diagnosis allows for adequate treatment, preventing progression of neuropathy and severe complications. For such, it is necessary to obtain an acurate clinical history, in addition to thorough neurological tests and additional tests, to identify signs of nervous fibers involvement. Its treatment depends on adequate glycemic control and neuropathic pain treatment, when present.
