    Oral hypoglygaemic activity of Ipomea aquatica in streptozotocin induced diabetic wistar rats and type II diabetics
    (Wiley, 2003) Malalavidhane, T.S.; Wickremasinghe, S.M.D.N.; Perera, M.S.A.; Jansz, E.R.
    Ipomoea aquatica Forsk is a common green leafy vegetable consumed in many parts of the world. The present study was designed to investigate theoral 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.

    Treatment seeking behavior and treatment practices of lymphatic filariasis patients with Lymphoedema in the Colombo district, Sri Lanka
    (SAGE Publishing, 2008) Wijesinghe, R.S.; Wickremasinghe, A.R.; Ekanayake, S.; Perera, M.S.A.
    This cross-sectional, descriptive study describes the treatment-seeking behavior of 413 lymphoedema patients attending 2 filariasis clinics in theColombo 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 treatmentranging 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
