[Show abstract][Hide abstract] ABSTRACT: The aim of the present study was to determine the parameters related to glycemic and insulinemic responses of type 2 diabetic patients to three low Glycemic Index (GI) breakfast meals and study the effects of each breakfast meal on a standard lunch meal. Breakfast meals were boiled chickpea, red rice (AT 353) meal and atta roti and the standard lunch was red rice (AT 353) with accompaniments. Study design was random cross over (n = 11 age: 40–62 year). GI and Insulinemic Indices (II) of breakfast meals were calculated with white bread as the standard. Serum glucose peak concentration of chickpea was significantly lower than rice (p = 0.0321), roti (p = 0.0019) and bread (p = 0.0001). GI of chickpea, rice and roti meals were 40 ± 7, 64 ± 11 and 88 ± 9 respectively. GI of chickpea was significantly lower than rice (p = 0.0466) and atta roti (p = 0.0016) meals. Chickpea and rice breakfast meals had low GI and atta roti medium GI. GI values in diabetic patients were not significantly different (p > 0.05) from that obtained previously in the same laboratory in healthy individuals. II of chickpea, rice and roti were 76 ± 13, 90 ± 20, 115 ± 28. Glycemic and insulinemic responses showed a linear positive relationship (r = 0.984) indicating that low GI was due to the macronutrients present in the meals. Breakfast meals given in the present study did not lower Glycemic nor insulinemic responses of the subsequent lunch meals. These data are useful especially in primary patient care for modulating diets of diabetic patients.

[Show abstract][Hide abstract] ABSTRACT: Chronic wounds have become a great threat to the quality of the life of patients. Chronic wounds due to colonization by bacteria may also lead to chronic degenerative diseases. This situation is much more serious when bacteria develop resistance to known antibiotics. New antibiotics with totally different structures are potentially capable of overcoming such bacteria. Flabelliferin B (F B) is one such compound in palmyrah (Borassus flabellifer L.) fruit pulp reported in 1998'. F B has a steroidal saponin structure with a molecular weight of 868, which was elucidated in 2002 as p-sitosterol with one glucosyl and two rhamnosyl groups (a 1, 2 and a I, 4) attached to the OH at C-3 of the aglycone 2 . F B has proven activity against bacterial species such as Escherichia coli, Staphylococcus aureus, Staphylococcus epidermidis, Pseudomonas aeroginosa, Proteus rettigeri and Aciinetobacter calcoacetius 1 . Flabelliferin B can also inhibit the activity of yeast. A naturally occurring fluorescent carotenoid is attached to the flabelliferin, which enhances the anti-microbial activity of this molecule against Escherichia coli J . Tests on wounds of rats, eye test on Wistar rats and New-Zea land white rabbits showed no allergenic or other toxic effects (Keerthi, Unpublished data). A preliminary human trial was carried out to determine the efficacy of the local application made from F B . Palmyrah fruits, which are known to be rich in F fl , were used in the preparation of new ointment. Pure F B with the binder was extracted and stored in a freezer until use in experiments. A panel of human volunteers (n =7) was selected for a patch test by applying F B on normal unbroken skin. Volunteers were given two plasters (1*1 cm 2) one soaked with 50 uL of 74 mg/mL of F B in distilled water as test and another soaked with water for control. Plasters were placed on the skin of the bicep muscles and independent comments on sensation were elicited.

[Show abstract][Hide abstract] ABSTRACT: This cross-sectional, descriptive study describes the treatment-seeking behavior of 413 lymphoedema patients attending 2 filariasis clinics in the Colombo district, Sri Lanka. A pretested, interviewer-administered questionnaire obtained information regarding sources and types of treatment taken, time taken for diagnosis, and details regarding diethylcarbamazine citrate (DEC) treatment. There was a mean delay of 2.37 years (SD 1.37) in diagnosing filariasis after the first appearance of limb swelling. General practitioners were the most frequent first-contact health care providers and the most visited source overall, followed by government hospitals and Ayurvedic practitioners. Approximately 95% of patients were on DEC treatment ranging from 10 days to 43 years (mean 2.5 years SD +/- 1.1). Sixty-one percent of patients reported always having taken the recommended DEC course. Nonsteroidal anti-inflammatory drugs, diuretics, and antibiotics were liberally prescribed. Approximately 97% had sought treatment from a medical practitioner for an acute adenolymphangitis attack. Despite the area being endemic for filariasis, there was a delay in treatment and inappropriate use of DEC in patients with chronic filarial lymphoedema.

[Show abstract][Hide abstract] ABSTRACT: The efficacy of a programme of community home-based care (CHBC) for lymphoedematous limbs was evaluated among 163 lymphoedema patients attending two filariasis clinics in Colombo. Each patient was interviewed and examined and his or her lymphoedema was graded during a baseline assessment, before the CHBC programme, and again, during a post-intervention assessment, after the patient had been in the programme for 1 year. The number of patients having entry lesions was 24% lower at the post-intervention assessment than at the baseline (P<0.001), with a reduction in the frequency of each type of entry lesion investigated. In the year the patients were in the CHBC programme, 30% fewer of them experienced at least one attack of adenolymphangitis (ADL; P<0.001), the mean number of ADL attacks/patient was lower (P<0.001), and the mean duration of each ADL attack suffered was slightly shorter (5.70 v. 5.84 days; P>0.05) than in the year before the baseline assessment. The reduction in the incidence of ADL attacks was greatest in the patients with the higher grades of lymphoedema. Approximately 66% of the patients perceived an improvement in their swollen limb post-intervention. Eleven patients had grade-II lymphoedema at baseline but only grade-I lymphoedema after being on the CHBC programme for a year (P=0.012). The programme appeared to increase the frequencies with which patients followed each of the limb-care measures considered and most of the measures for the home management of ADL attacks that were investigated. It is recommended that the CHBC programme be implemented as a national programme in Sri Lanka.

[Show abstract][Hide abstract] ABSTRACT: Knowledge of filariasis and perceptions of the disease were explored among 413 lymphoedema cases attending two filariasis clinics in the Colombo district of Sri Lanka. The information was collected in interviews based on a pre-tested, interviewer-administered questionnaire. Only 15% of the patients had initially attributed their limb swelling to filariasis. Most knew that filariasis resulted from mosquito bites (81.1%) and that the disease is transmissible (59.8%) and preventable (74.3%). The majority did not know, or were uncertain, whether filariasis causes swelling of the breasts in females (68.5%), scrotal swelling (60.7%) or dry cough/breathlessness (62.7%). Most (60%) of the interviewees wrongly believed that chronic filarial lymphoedema could be cured, primarily by long-term treatment with diethylcarbamazine. Knowledge of filariasis was significantly associated with level of education (P<0.05). Curiously, compared with the male interviewees, the females interviewed were much less likely to say that filariasis was the cause of their initial swelling (P<0.001). Those who had suffered with the disease for more than 1 year were not significantly more knowledgeable about the disease than the interviewees who had developed symptomatic filariasis more recently. Knowledge about the symptoms of filariasis was generally poor in the study population. In order to dispel several common myths about the disease, health-education programmes, that are targeted both at the community in general and at primary-care providers, are clearly needed.

[Show abstract][Hide abstract] ABSTRACT: Information on the physical and psychosocial disability of lymphatic filariasis in Sri Lanka is scarce. Therefore this study was carried out to describe the physical disability and psychosocial impact associated with chronic lymphoedema in patients attending filariasis clinics in the Colombo district, Sri Lanka.
Four hundred and thirteen patients with lymphoedema of limbs attending filariasis clinics in Werahera and Dehiwala in the Colombo district were enrolled in the study after obtaining informed written consent. Data were collected using a pre-tested, interviewer-administered questionnaire and analyzed using SPSS.
Majority (95%) of patients had lower limbs affected and there was a significant association with difficulty in walking (p = 0.023). The swollen limb affected the work of 87 (52%) of employed patients and 26 persons reported loss of job. Approximately 25% and 6% reported having problems interacting with the community and family, respectively and 8.7% felt that they were rejected by society. The swollen limb was perceived as a major problem by 36.8% of patients. Of the married persons, 5.7% and 6.2% reported sexual and marital problems respectively, due to their swollen limb/s. Of those who had marital problems, 77.3% reported sexual problems as well (p < 0.001).
Lymphoedema significantly affects physical, psychological and social functioning in affected individuals. Morbidity control, in addition to control of physical disability, should target the psychosocial consequences.
[Show abstract][Hide abstract] ABSTRACT: Ipomoea aquatica Forsk is a common green leafy vegetable consumed in many parts of the world. The present study was designed to investigate the oral hypoglycaemic activity of Ipomea aquatica in streptozotocin induced diabetic Wistar rats, and Type II diabetic patients. Experimental diabetes was induced with streptozotocin in Wistar rats. The rats were then divided into test and control groups. In addition to the standard feed given to both groups the test was fed with the shredded leaves of Ipomoea aquatica (3.4 g/kg) for one week. Type II diabetic patients were subjected to a glucose challenge before and after a single dose of blended I. aquatica. Patients acted as their own controls. The results revealed that consumption of the shredded, fresh, edible portion of I. aquatica for one week, effectively reduced the fasting blood sugar level of streptozotocin-induced diabetic rats (p = 0.01). When subjected to a glucose challenge, the Type II diabetic subjects showed a significant reduction (p = 0.001) in the serum glucose concentration 2 h after the glucose load. However, it was not significantly reduced at 1 h (p < 0.09) post glucose load. There was a 29.4% decrease in the serum glucose concentration of the diabetic patients when treated with the plant extract.
