The findings demonstrate that anti-hyperglycemic activity of A. marmelos is mediated by the inhibition of carbohydrate digestion and absorption, and improvement of insulin action to uptake glucose in peripheral tissue. Additional study is required to correlate A. marmelos extracts' specific mechanism of glucose-fiber binding capacity and glucose transporters.

The diagnosis of typhoid fever currently depends on isolation of Salmonella Typhi from blood. The sensitivity of blood culture is very low due to prior antibiotic treatment which is a common practice in Bangladesh. The sensitivity of blood culture also decreases at later stage of the disease. Widal test is the most utilized test in Bangladesh next to blood culture because it is inexpensive, less invasive. But the result of the test is controversial due to false negative & false positive results in some cases.  In this study, a recently introduced polymerase chain reaction-based technique (which has 100% specificity for S. Typhi) was compared with widal test among 80 clinically suspected typhoid fever cases.  Among 80 cases, the respective figures of positivity for PCR & widal test were 70% & 43.75% respectively.  It can be concluded that PCR based technique is more sensitive & much superior to widal for diagnosis of typhoid fever.

The purpose of this study was to show the antidiabetic effect of ethanolic extract of Aloe vera gel in alloxan induced hyperglycaemic mice. Ethanolic extract of Aloe vera gel was orally administered for four weeks at a dose of 300mg/kg body weight. Weekly estimates of fasting blood glucose level in normal non-diabetic and alloxan induced hyperglycaemic mice were assessed. Ethanolic Aloe vera gel extract revealed no blood glucose lowering action upon non-diabetic mice. But, a significant reduction in blood glucose level (p<0.001) was seen in diabetic mice, when compared with diabetic control. Similar results were found when compared with a standard antidiabetic drug, gliclazide. To conclude, as administration of ethanolic extract of Aloe vera gel significantly reduces blood glucose level in hyperglycaemic mice, it can optimistically emerge as a new hope in the management of diabetes mellitus.

This study was conducted to evaluate the effect of different extracts of Aloe Vera gel in alloxan induced hyperglycaemic mice.Three different extracts of Aloe Vera gel (dried extract, ethanolic extract and fresh raw extract) were orally administered at 300 mg/kg body weight for 28 days. The fasting blood glucose level was estimated both in normal and alloxan induced hyperglycaemic mice. It was found that, when compared with the control, there was a significant reduction in blood glucose level in all three experimental groups. Ethanolic and fresh raw gel extracts were more effective than the dried extract. The extracts produced similar results when compared with gliclazide. It can be concluded that, the administration of Aloe Vera gel extract significantly decreases blood glucose level in hyperglycaemic mice. Aloe Vera gel can therefore be a natural remedy and a cost effective resource for the management of diabetes.Bangladesh Med J. 2015 May; 44 (2): 61-66
