Objective. To evaluate the hypoglycemic effect of Picris japonica Thunb (Asteraceae) on KK-Ay mice. Methods. The hypoglycemic effect of Picris japonica aqueous extract (PJE) in a spontaneous type 2 diabetic model (KK-Ay mice) was studied in the present research. PJE was administrated at doses of 700 mg/kg and 350 mg/kg (calculated as crude herb) for 14 days and blood glucose, oral glucose tolerance test, plasma insulin level, and blood lipid were evaluated. Meanwhile, Rosiglitazone was used for the positive control. Results. It was found the PJE treatment significantly reduced blood glucose level and improved oral glucose tolerance ability (p < 0.01 or p < 0.05) in a dose-dependent manner compared to the control diabetic mice. The blood insulin levels were significantly reduced in PJE-treated mice (700 mg/kg) and Rosiglitazone compared with the diabetic control (p < 0.01). Compared with the control diabetic group, the serum total cholesterol, triglyceride, and low density lipoprotein cholesterol were reduced by PJE (700 mg/kg) and Rosiglitazone (p < 0.05), and the serum high density lipoprotein cholesterol was significantly increased only by Rosiglitazone (p < 0.01). Conclusions. The findings demonstrate that Picris japonica has remarkable antidiabetic effect in diabetic KK-Ay mice, which suggests that Picris japonica may be beneficial to the treatment of type 2 diabetes mellitus.

AbstractBackground:(commonly known as Bael, golden apple) was formerly described to have anti-hyperglycemic activity. The present study aimed to explore the possible effects, in depth, ofMethods:This research begins with fasting blood glucose and oral glucose tolerance test (OGTT) to evaluate the primary anti-hyperglycemic effect in chemically induced type 2 diabetic rats. Furthermore, the plasma insulin concentration and serum glucose level were studied, which include measuring the sucrose content in six different segments of the gastrointestinal (GI) tract of the rats following oral sucrose feeding. An in situ, perfused, intestinal model in rats and glucose-fiber binding assay were conducted to find the effects ofResults:Treatment of extracts suppressed blood glucose elevation after oral sucrose (2.5 g/kg) administration and significantly (p<0.05) improved oral glucose tolerance in type 2 diabetic rats.Conclusions:The findings demonstrate that anti-hyperglycemic activity of

Background: The anti-hyperglycemic potential of methanol stem bark extract of Anacardium occidentale (MSBEAO) was investigated using an alloxan-induced diabetic rat model. Alloxan administration induces the generation of free radicals which can affect antioxidant status resulting in the disruption of the β-cells of the pancreas. Therefore, this study examines the antioxidant potential of the plant extract and the ameliorating effect on the pancreas of alloxan-induced diabetic rats. Methods: Diabetes was induced by intraperitoneal injection of 150 mg/kg body weight of alloxan monohydrate. MSBEAO, at a concentration of 100 or 200 mg/kg b.w. was orally administered to alloxan-induced diabetic rats and normal rats. The hypoglycemic effect, oral glucose tolerance test, and biochemical assay of alloxan-induced diabetic rats were assayed using standard procedures. Results: Preliminary phytochemical screening of the extract revealed the presence of alkaloids, tannins, saponins, terpenoids, carbohydrates, and phenols at moderate concentrations. The lethality dose (LD50) of the plant extract was found to be equal to or less than 5000 mg/kg b.w. The hypoglycemic effect of the extract on the non-diabetic rats revealed a significant (p<0.05) decrease in the blood glucose concentration of animals administered with 1 g/kg b.w. of the extract, compared to normal control rats administered with normal saline. In the oral glucose tolerance test, the methanol extract exerted the highest response, similar to glibenclamide after 15 and 30 minutes of administration, compared to the control rats. The methanol extract yielded the highest blood glucose lowering effects after 9 days of treatment (p<0.05), compared to diabetic rats administered with normal saline and 0.3 mg/kg b.w. of glibenclamide. Administration of the extract at 200 mg/kg b.w. showed improved pancreas architecture and regeneration of the β-cells, compared with the pancreas of animals in the other groups. Conclusion: The results of this study suggest that MSBEAO is a potentially effective agent for the management of diabetes which might result from the antioxidant-generating capacity of the stem bark.

Introduction: Gestational diabetes mellitus is common disorder in pregnancy. It is associated with adverse pregnancy outcome. There is no consensus regarding the optimal approach to screening of gestational diabetes mellitus. The present study has tried toobserve the value of fasting blood glucose in screening of gestational diabetes. Objective: To determine the frequency of patients in whomfasting blood glucose and 100gm glucose tolerance show agreement for screening of gestational diabetes mellitus at 24 -28 wks. Studydesign: Comparative cross sectional study. Settings: The study was conducted at Gynecology and Obstetrics department Shaikh ZayedFederal Post Graduate Institute Lahore. Duration of study with dates: 6 months from 12Nov 2010 to 11 May 2011. Material and method: Thestudy included 135 booked patients with positive family history of diabetes mellitus. All patients underwent fasting blood glucose at 24-28 weeksof gestation, regardless of results of fasting blood glucose on next visit they underwent 100g oral glucose tolerance test (OGTT). The agreementbetween fasting blood glucose and 100g oral glucose tolerance test was calculated in frequency and percentages. Results: The mean age ofwomen in studied population was 27.15±3.70.Out of 135 patients 86.7 %( 117) showed agreement between results of fasting blood glucose and100g OGTT while 13.31 %( 18) showed no agreement between both of the tests. Conclusions: Fasting blood glucose is a good screeningoption for gestational diabetes mellitus along with positive history. It provides a simple, cheap and more practical test for screening of gestationaldiabetes mellitus. However diagnostic confirmation with 100g OGTT should be done.

<p>The purpose of this study is to evaluate the hypoglycaemic properties and preliminary phytochemical screening of <em>Uveria chamae</em>. The hypoglycaemic properties of <em>Uveria chamae</em> was assessed on normoglycaemic rat that received single dose of the extract at 250 and 500 mg/kg body weight and blood glucose levels estimated at 2, 4, and 6 hours (single dose study). The hypoglycaemic property of the extract was also evaluated in normoglycemic rats by oral glucose tolerance test. Phytochemical screening of the extract for the presence of secondary metabolites was performed with standard methods. The extract showed a significant (p&lt;0.05) reduction in blood glucose levels at 2h and 6h compared to control.  The oral glucose tolerance test  result also showed a significant decrease (p&lt;0.05) in blood glucose levels . The study showed that the extract, <em>Uveria chamae</em> has hypoglycaemic properties which may be accounted for by the presence of the phytochemicals.</p><p> </p>
