Effect of alcoholic extract of roots of Rubia cordifolia was studied on elevated blood glucose level in alloxan treated animals. The extract reduced the blood sugar level raised by alloxan. Effect of alcoholic extract was also investigated on cold restraint induced stress and on scopolamine-induced memory impairment. Alcoholic extract enhanced brain gamma-amino-n-butyric acid (GABA) levels and decreased brain dopamine and plasma corticosterone levels. Acidity and ulcers caused due to cold restraint stress were inhibited by alcoholic extract. Animals treated with alcoholic extract spent more time in open arm in elevated plus maze model. It also antagonized scopolamine induced learning and memory impairment. Baclofen induced catatonia was potentiated by alcoholic extract.

    • "In present study, piracetam treated group showed significant decrease in TL (Fig. 1), as compared to control group. Patil et al. [31] have reported similar decrease in TL after piracetam treatment in EPM. The decrease in TL was not significant in remaining groups (Fig. 1). "

    ABSTRACT: There is a strong association between depression and memory impairment. The present study aims to assess the nootropic activity of duloxetine and piracetam combination. Male Swiss Albino mice were divided randomly into 4 groups. Treatment of normal saline (10 ml/kg), duloxetine (10 mg/kg), piracetam (100 mg/kg), and duloxetine (5 mg/kg) plus piracetam (50 mg/kg) were given through intra-peritoneal route to group I-IV, respectively. Transfer latency in elevated plus maze (EPM) and time spent in target quadrant in Morris water maze (MWM) were recorded. Estimation of brain monoamines in hippocampus, cerebral cortex, and whole brain were done using HPLC with fluorescence detector. Piracetam treated group showed significant decrease in transfer latency in EPM and increase in time spent in target quadrant recorded in MWM. Combination treated group failed to produce statistically significant nootropic effect in both EPM and MWM. Combination treated group failed to increase brain monoamine levels when compared against duloxetine and piracetam treated groups, separately. But there was exception of significant increase in norepinephrine levels in hippocampi when compared against duloxetine treated group. Results indicate no cognitive benefits with piracetam plus duloxetine combination. These findings can be further probed with the aim of understanding the interaction between duloxetine and piracetam as a future endeavor.

    ABSTRACT: Diabetes mellitus, an epidemic metabolic disorders characterized by high blood glucose level associated with various macrovascular and microvascular complications, is one of the main causes of human suffering across the globe. Researchers around the world mainly focused on insulin, insulin analogues, oral hypoglycemic agents and various other complementary and alternate medicines to control the blood glucose levels in diabetes. The present review summarizes the disorders associated with elevation of blood glucose level, biochemical & endocrinological aspects and the current strategies to control. The emphasis has been laid in particular on the new potential biological targets and the possible treatment as well as the current ongoing research status on new generation hypoglycemic agents.

    ABSTRACT: The present study was performed to examine the effect of Eugenia caryophyllata (Myrtaceae) on learning and memory, and also evaluate whether it can modulate oxidative stress in mice. Passive avoidance step-down task and elevated plus-maze were used to assess learning and memory in scopolamine-treated mice. Oxidative stress parameters were also assessed in brain samples by estimating the malondialdehyde (MDA) and reduced glutathione (GSH) levels at the end of the study. Scopolamine (0.3 mg/kg, i. p.) produced impairment of acquisition memory as evidenced by a decrease in step-down latency and an increase in transfer latency on day 1, and also impairment of retention of memory on day 2. Pretreatment with clove oil (0.05 mL/kg and 0.1 mL/kg) for 3 weeks significantly reversed the increase in acquisition latency and all the doses (0.025, 0.05, 0.1 mL/kg, i. p.) reversed the increase in retention latency induced by scopolamine (0.3 mg/kg, i. p.) in elevated plus-maze. However, 0.05 mL/kg clove oil attenuated memory deficits in the passive avoidance step-down task. Brain samples showed a significant decrease in MDA levels in the group treated with clove oil (0.05 and 0.025 mL/kg). GSH levels were also increased in clove oil-treated mice though the results were not significant. Thus, it can be concluded that clove oil can reverse the short-term and long-term memory deficits induced by scopolamine (0.3 mg/kg, i. p.) and this effect can, to some extent, be attributed to decreased oxidative stress.
