Context. Nigella sativa seeds are usually used as traditional medicine for a wide range of therapeutic purposes. Objective. To investigate the subacute toxicity of NS aqueous extract and select its lowest dose to study its antidiabetic effect. Methods. 5 AqE.NS doses (2, 6.4, 21, 33, and 60 g/Kg) were daily administered to mice by gavage. Biochemical parameters measurements and histological study of the liver and the kidney were performed after 6 weeks of supplementation. Thereafter, and after inducing diabetes by alloxan, rats were treated by 2 g/Kg of AqE.NS during 8 weeks. Metabolic parameters were measured on sera. A horizontal electrophoresis of plasmatic lipoprotein was conducted. Glycogen, total lipids, and triglycerides were measured in the liver. TBARS were evaluated on adipose tissue, liver, and pancreas. Results. AqE.NS showed no variation in urea and albumin at the 5 doses, but hepatotoxicity from 21 g/Kg was confirmed by histopathological observations of the liver. In diabetic rats, AqE.NS significantly decreased glycemia, TG, T-cholesterol, LDL-c, and TBARS and showed a restored insulinemia and a significant increase in HDL-c. Results on the liver indicated a decrease in lipids and a possible glycogenogenesis. Conclusion. AqE.NS showed its safety at low doses and its evident antihyperglycemic, antihyperlipidemic, and antioxidant effect.

Background: Angiogenesis is important for the typical physiological activities such as cure from injury, menstrual cycle and embryo growth. It is also plays a crucial role in several pathological conditions in cancer. Antiangiogenesis, e.g., inhibition of blood vessel growth, is being investigated as a way to prevent the growth of tumors and other angiogenesis-dependent diseases. The chick embryo chorioallantoic membrane (CAM) is commonly used as an experimental in vivo assay to study both angiogenesis and antiangiogenesis in response to tissues, cells or soluble factors. Given the high occurrence of cancer worldwide and the major source of the discovery of new lead molecules are medicinal plants. The objective of the present research was to study the antiangiogenic property of “aqueous extract of Nigella sativa seeds” using chick chorioallantoic membrane (CAM) assayMethods: The chick chorioallantoic membrane (CAM) assay for screening the effect of Nigella sativa on anti-angiogenesis was performed according to the method given by Ribatti and co-workers.Results: The results of present study significantly increased the antiangiogenic effect on CAM by decreasing the proliferation of capillary networks in a dose (50 to 300 µg/egg) dependent manner which is probably related to the inhibition of neovascularization.Conclusions: It is concluded that aqueous extract of N. sativa seeds possesses significant antiangiogenic activity, and this is a possible rationale for its folkloric use as an anticancer agent.

Objective: The present study was aimed to evaluate the effect of the aqueous extract of Tinospora cordifolia (AETC) against cyclophosphamide-induced immunosuppression and systemic Candida albicans infection in a murine model. Methods: The protective effect of AETC against cyclophosphamide-induced leukopenia was evaluated by quantitative and qualitative analysis of the leukocytes. The immune-stimulating potential of AETC on macrophages was assessed by determining the levels of secreted cytokines. To determine the direct antifungal activity, AETC or fluconazole was administered to C. albicans infected mice. The efficacy of treatment was assessed by determining the survival rate, kidney fungal burden, the organ index and liver inflammation parameters. Results: Cyclophosphamide administration resulted in substantial depletion of leukocytes, whereas AETC treatment induced the recovery of leukocytes in cyclophosphamide-injected mice. Moreover, AETC treatment of macrophages resulted in enhanced secretion of IFN-γ, TNF-α and IL-1β. C. albicans infected mice treated with AETC at the doses of 50 and 100 mg/kg exhibited 40% and 60% survival rate, whereas the mice treated with fluconazole at a dose of 50 mg/kg showed 20% survival rate. Like survival data, the fungal load was found to be the lowest in the kidney tissues of mice treated with AETC at a dose of 100 mg/kg. Interestingly, mice infected with C. albicans demonstrated improvement in the organ indices and liver functioning after AETC treatment. Conclusion: These results suggest that AETC may potentially be used to rejuvenate the weakened immune system and eliminate systemic candidiasis in mice.

Study Results

Background: Diabetes mellitus is major issue to public health as its prevalence is rising day by day. Synthetic agents available for the diabetic treatment are expensive or produce undesirable side effect on chronic use and some of them are not suitable during pregnancy. Herbal medicines accepted widely due to side effects and low cost. Objective: The aim of present study was to evaluate the activity of Withania coagulans extract using In-vitro and In-vivo model. Methods: Different three types of Withania coagulans extract were prepared using aqueous (W1), Alcohol (W2) and hydro-alcoholic (50:50) mixture (W3). In-vitro Anti-diabetic activity of the all three extracts evaluated using RINm5F Pancreatic beta cells.Further, n-vivo anti-diabetic evaluation performed by administering 50 mg/kg (p.o) aqueous extract for 7 days in Streptozotocin (STZ)-induced mice. Body weight of the animals was also determined to perform acute toxicity study. Results: The results of in –vitro cell based study indicated that among all three extract, aqueous extract (W1) of Withania coagulans showed potential increase in inulin release. The EC50 of the W1 (249.6 µg/L) which is compared with standard (Glibenclamide) EC50. From the results of In-vitro study, W1 subjected for acute toxicity study and the acute toxicity study results indicated LD50 of 50mg/kg. Diabetic rats treated with W1 extract at oral dose of 50 mg/kg for 7 days showed 34.17% reduction in blood glucose in comparison to untreated diabetic (STZ-induced) rats. Blood glucose levels of Standard treated (Glibenclamide) and control untreated. Conclusion: In conclusion, results of pancreatic beta cell based study showed increase in insulin release by administration of extract. Further aqueous extract (W1) was potentially reduced blood glucose level in STZ induced diabetic mice.
