ABSTRACT
Aims: To investigate the effect of ethanol extract of Coccinia grandis Lin (Cucurbitaceae) leaf in glucose and cholesterol lowering activity in animal model. Study Design: Extraction, glucose and cholesterol lowering activity evaluation. Place and Duration of Study: Department of Pharmacy, North South University, Dhaka between June 2012 and December 2012. Methodology: Glucose and cholesterol lowering effect of the ethanol extract of C. grandis leaf was evaluated using the alloxan-induced diabetic rat and compared the activity with diabetic control and antidiabetic drug (Glibenclamide). Ethanol extract (25mg/kg) of C. grandis and Glibenclamide were administered to normal and experimental diabetic rats for the duration of 10 days. Results: Phytochemical screening showed the presence of alkaloids, flavonoids, saponins, cardenolides and polyprenols in significant amounts. In the alloxan-induced diabetic rat model, C. grandis (25 mg/kg) significantly (p<0.05) lowered fasting blood glucose levels. C. grandis extract (25 mg/kg) also produced significant (p<0.05) total cholesterol lowering and HDL increasing (p<0.05) effects. Surprisingly, body weight was increased significantly (p<0.05) in the C. grandis treated diabetic group. Conclusion: These results suggest that the ethanol extract of C. grandis leaf possesses significant glucose and cholesterol lowering activity in animal model, thus supporting the usage of the plant in traditional medicine as an anti-diabetic medication.
ABSTRACT
In this present study, the bark extracts of Averrhoa bilimbi were subjected to the thrombolytic activities were assessed by using human erythrocyte and the results were compared with standard streptokinase (SK). On the other hand, bark extracts of A. bilimbi revealed moderate antibacterial activity against some microorganisms used in the screening. Preliminary phytochemical investigation suggested the presence of flavonoids, saponins and alkaloids.
ABSTRACT
We analyzed the prevalence of polypharmacy among cardiac patients in the Natioal Institute of Cardiovascular Diseases of Dhaka, Bangladesh. Polypharmacy was defined as consumption of six or more drugs at the same time. We entered the drugs that were prescribed into the Drug Interaction Checker provided by MedScape online edition. Almost 85% of cardiac patients met criteria for three types of polypharmacy (minor, moderate and serious). However, serious and moderate types of polypharmacy were not influnenced by the increase in number of disorders (polymorbidity) as well as by the total number of drugs taken. The most frequent cause and threat that is associated with polypharmacy comes primarily from the quality of drug-drug interactions and not the total number of drugs prescribed. Most of the dangerous consecuences of polypharmacy came from the interaction of Clopidogrel with either Aspirin or PPIs. Our study emphasizes the need of informing doctors more about the problem of polypharmacy. Careful and thoughtful drug prescription strategy seems to be able to eliminate most of the cases of polypharmacy even in patients who are suffering from a multiplace disorders simultaneously. The results also provide support for development of new drugs that take into account compatibility with other medication, especially in elderly people.
