Atherosclerosis is one of the risk factors for coronary artery disease. The present study highlights the antiatherosclerotic activity of Methanolic extract of polyherbal preparation in experimentally induced atherosclerotic rats. Atherosclerosis was developed in male Albino Wistar rats, which were randomly divided into five groups of six animals each; by feeding with high cholesterol diet for 21 days. Group 1 received normal diet. Group 2 received high cholesterol diet (HCD) which served as control. Group 5 served as standard, administered with Atorvastatin (10 mg/kg) along with HCD and Group 3 and Group 4 were administered with methanolic extract of polyherbal preparation (300 mg/kg and 600 mg/kg) along with HCD. Methanolic extract of polyherbal preparation reduced the raised serum level of total cholesterol, triglyceride , LDL ,VLDL and increased the serum HDL level as compared to the control group(High cholesterol group).There was increased HMG CoA/Mevalonate ratio in liver. There was also depletion of GSH content and increased level of SOD and MDA in liver. Methanolic extract of polyherbal preparation treated groups...

Pregnancy can be the most paranormal and exciting time for expectant mother. Nature provides us with many tools for supporting both the mother and baby through this time of growth and renewal, to strengthen the spirits and body to promote a healthy pregnancy and birthing process.

The women self administer herbal medicines both before and after pregnancy often without any recognition of their potential hazards. The use of herbal supplements in pregnancy and lactation is likely to be relatively high and its importance ascertains what supplements women are taking. Pregnancy and lactation care providers should be aware of common herbal supplements used by women and of evidence regarding potential benefits or harm.

Thiazolidinediones (TZDs) were widely used for the treatment of type 2 diabetes. Recent studies have shown that TZDs have paradoxical effects on cardiovascular diseases. The objective of the present study was to investigate the effect of TZDs (Rosiglitazone and Pioglitazone) in High Fructose Diet (HFD) induced hypertension in rats. HFD was given for 14 weeks. After 8 weeks of hypertension induction period, treatment phase was started with Rosiglitazone (ROSI 10 and 30 mg/kg, p.o.) and Pioglitazone (PIO 10 and 30 mg/kg, p.o.) to the respective groups which were continued till 6 weeks. Systolic Blood Pressure (SBP) was measured weekly and serum glucose, triglyceride, cholesterol and HDL-C were measured at the end of study period. In HFD fed rats hypertension was observed after 8 weeks. Treatment with the test drugs significantly reversed the changes in serum enzyme levels as well as SBP made by HFD feeding compared to the control group. The study concludes that TZDs possess antihypertensive effect as exhibited in the present experimental...

Ceiba pentandra (C. pentandra) has been traditionally used in the ayurveda system of medicine for the treatment of obesity and atherosclerosis. The present study was undertaken to evaluate anti-obesity and hypolipidaemic activity of the ethanolic leaf extract of C. pentandra in Cafeteria diet (CD) treatedWistar albino rats. Obesity was induced in Wistar albino rats by feeding CD daily for twelve weeks. Body weight was measured initially and then every week thereafter. Food and water intake was measured daily. On day 85th, the serum biochemical parameters were estimated and the animals were sacrificed with over dose of anesthetic ether. The liver and fat pads (perirenal, mesenteric and epididymis) were removed and weighed immediately. The intestinal activity of enzyme alkaline phosphatase (ALP) was determined. Administration of C. pentandra (125 mg/kg) prevented the increase in body weight in cafeteria diet treated animals. Administration of C. pentandra showed significant decrease in body weight gain in CD treated obese rats. The significant decrease in ALP level was observed in C. pentandra treated rats. Administration...

The use of medicinal plants and preparations derived from them as dietary supplements, nutraceuticals, functional foods and herbal medicinal products has become more widely accepted in developing countries. Therefore, it is important to evaluate the adverse effects of these plants and their preparations. The objective of this study was to evaluate the safety of the methanol extracts Plumeria acuminata (MEPA) and Galega purpurea (MEGP) by single the long-term oral administration in mice. The study of chronic toxicity was determined by oral feeding male mice daily with the MEPA and MEGP at the dose of 300, 600 and 1,200 mg/kg body weight continuously for 270 days. The results of chronic toxicity showed no abnormalities in the test groups as compared to the controls. Hematological and blood chemical values in treated groups were normal in comparison with the control group. Non-toxicity effect of MEPA and MEGP were present as no changes in body weight, internal organ weight, and general behaviors. Macroscopic or microscopic of internal organs or tissues in treated rats...
