Glycemic control and antioxidant potential of distinct fractions of camelus dromedaries fresh milk in streptozocin induced diabetic rats.

To analyze the antiglycemic effects and to evaluate the anti-oxidant levels in pre and post-camel milk fractions treated albino diabetic rats, sixty male Swiss albino rats weighing 30-40gm aged 2 to 3 months were randomly divided into six groups, A, B, C, D, E & F, each comprised of 10 animals. as Group A: Normal control, Group B: Streptozocin induced Diabetic group while Groups C, D, E & F were diabetic groups treated with various fractions of camel milk. Noteworthy alteration in blood glucose and antioxidant activity was observed between disease control (group B) and all the treated groups with a percentage decrease of about 25%, 12.98%, 11.57% and 10.17% in blood sugar in groups C, D, E and F respectively. Changes in total antioxidant capacity were significant with the rise of 92.30%, 30.76%, 46.15% and 38.46% respectively in groups C, D, E and F. Percentage difference in superoxide dismutase between group B and Group C of 85% was highest as compared to 45.90 %, 52.45% and 39.34% for groups D, E and F. Group C also showed a significantly higher increase in serum copper, zinc and Vitamin C. It is inferred that Camel milk has significant antiglycemic and antioxidant potential and may prove good complementary therapeutics for diabetes.

Analysis of dose and duration dependent effects of Allium sativum Linn and other hypocholesterolemic agents exhibited on dyslipidemia in patients with essential hypertension.

Globally, cardiovascular diseases (CVD) are one of the most significant cause of organ failure, mortality and substantial escalation of health care cost. Dyslipidemia and hypertension poses significant risks in cardiovascular diseases and morbidity and mortality can be minimized by altering risks factors. Dyslipidemia is one of the major leading cause of rise of global incidences and socioeconomic burden which necessitates to explore the pharmacological options of significant antilipemic activity with minimal untoward effects at affordable price. Allium Sativum (Garlic) proved medicinally effective in different clinical trials, but further investigations are required to investigate its effects on diabetes, hypertension and dyslipidemia based on variable doses and duration. In this study dose and duration dependent effects of Garlic were evaluated on hypertensive patients with dyslipidemia. Study was randomized, single blind and placebo controlled. Effects of tablets of garlic (KWAI) 300 mg in doses of daily 0.3g, 0.6g, 0.9g, 1.2g and 1.5g for 24 weeks were compared in humans. Each tablet contains 1.3 percent of alliin and 0.6 % of allicin. Results showed remarkable improvements in different serum lipid levels (Cholesterol, Triglycerides, Low density lipoproteins and High density lipoproteins) based on different doses and duration as compared to placebo and standard Lipid-lowering agent simvastatin.

Effects of Allium sativum (garlic) on systolic and diastolic blood pressure in patients with essential hypertension.

The present study evaluated the effects of garlic on blood pressure in patients with essential hypertension. Patients (n=210) with stage 1 essential hypertension were divided into 7 groups named as A, B, C, D, E, F and G. Each group comprised of 30 patients. Each patient in group A, B, C, D and E has received garlic tablets at the dose of 300/mg. 600/mg, 900/mg, 1200/mg and 1500/mg in divided doses per day respectively for 24 weeks while Group F & group G were given tablet atenolol and placebo respectively. Blood pressure readings were recorded at weeks 0, 12 and 24. Present study showed significant decrease in both Systolic and Diastolic blood pressure in both dose and duration dependent manner. In each garlic treated group, significant reduction in SBP and DBP (p<0.005) were observed when compared with atenolol (P<0.005) and placebo.

Hepatoprotective and antioxidant activities of flowers of Calotropis procera (Ait) R. Br. in CCl4 induced hepatic damage.

Hepatoprotective activity of 70% ethanolic extract of flowers of C. procera was studied against CCl4 induced hepatic injury in albino rats and mice. In addition, antioxidant activity was studied by in vitro models. Pre-treatment with 70% ethanolic extract (CPA) reduced the biochemical markers of hepatic injury like serum glutamate pyruvate transaminase, serum glutamate oxaloacetate transaminase, alkaline phosphatase, bilirubin, cholesterol, HDL and tissue glutathione (GSH) levels. Similarly pretreatment with CPA reduced the CCl4 induced elevation in the pentobarbitone sleeping time. Histopathological observations also revealed that pretreatment with CPA protected the animals from CCl4 induced liver damage. CPA demonstrated dose dependant reduction in the in vitro and in vivo lipid peroxidation induced by CCl4. In addition it showed dose dependant free radical scavenging activity. The results indicate that flowers of C. procera possess hepatoprotective property possibly because of its anti-oxidant activity. This property may be attributed to the quercetin related flavonoids present in the flowers of Calotropis procera.
