Background and Purpose: Integrated teaching is new in pharmacology. In the present study, evaluation and comparison of integrated teaching, conventional theory teaching and tutorial has been done. Material and methods: Ten pre and post tests were conducted each for integrated teaching, theory class and tutorial for 126 students. Student’s attitude towards these teaching methods and bedside clinical teaching were analysed. Results: There was significant improvement in post test scores when compared with pre test scores in all three types of teachings. When post and pre test’s differences were compared, conventional theory teaching was significantly effective than integrated teaching which in turn was significantly effective than tutorial. Student’s attitude tests revealed merits and demerits of theory class, tutorial, integrated teaching and bedside clinical teaching. Conclusion: Integrated teaching will promote active learning. Conventional theory and tutorial classes are popular due to their easiness in acquiring and consolidation of the knowledge respectively. These findings will help in further educational...

The aim of the present study was to evaluate antidiabetic and antioxidant potential of Aloe vera (AV) in alloxan induced diabetes in albino rabbits. Experimental Diabetes was induced in rabbits with alloxan(80mg/Kg body weight)and animals showing fasting blood glucose levels more than 250mg/dl were considered as diabetics and divided into four groups of six each (n=6). Group I: Normal control rabbits, Group II: Alloxan induced diabetic rabbits, Group III: Diabetic rabbits received AV gel extract (300 mg/Kg) in aqueous solution for 21 days, Group IV: diabetic rabbits given glibenclamide (600ug/kg) in aqueous solution. All the drugs were administered orally (using an intra gastric tube) in a single dose in the morning for 21 days. Blood samples were collected from the marginal vein of pinna of overnight fasted rabbits (Blood sugar, glycosylated hemoglobin (HbA1c), Malondialdehyde (MDA), reduced glutathione (GSH), total thiols (PSH) and Superoxide dismutase (SOD).Oral administration of AV showed potent antihyperglycemic and anti-lipidperoxidative effect in diabetic animals. Simultaneously, the levels of protective antioxidant enzymes (SOD, GSH and PSH) were...

Carbon tetrachloride is a xenobiotic that produces hepatotoxicity. Aqueous extract Volvariella volvacea (500, 1000 mg/kg, p.o) showed significant hepatoprotective activity against carbontetrachloride induced hepatotoxicity in rats by normalizing the levels of serum AST, ALT, ALP, LDH and total bilirubin. The extract improved the activity of Catalase (CAT), Superoxide dismutase (SOD), and hepatic glutathione (GSH) content and depleted the lipid peroxidation levels in a dose dependent manner. Silymarin was used as the standard...

The objective of this study is to induce experimental diabetes mellitus using Alloxan monohydrate in normal adult albino rats and study the anti‐diabetic activity of changes in body weight, consumption of food and water, volume of urine and levels of glucose between normal and diabetic rats. Diabetes mellitus (DM) is a common endocrine disorder. Hypoglycemic agents from natural and synthetic sources are available for treatment of diabetes. Indian medicinal plants have been found to be useful to successfully manage diabetes. The effect of methanolic and water extract of Solanum nigrum leaves was investigated in normal, glucose load conditions and Alloxan monohydrate ‐induced diabetic rats. Significant hypoglycemic activity was exhibited by the poly herbal...

Anti-ulcer activity of the Solanum nigrum L. extracts was studied in rats by using pylorus ligated ulcer model. Rantidine was used as the standard drug for comparison. The animals were sacrificed after 19 hrs after the ligation. Stomach was dissected out and contents were drained into tubes and were centrifuged at 1000 rpm for 10min and volume was noted. The PH of gastric juice was recorded using a PH meter. The contents were subjected for analysis of free and total acidity. The numbers of ulcers per stomach was noted and severity of ulcers scored. Then the blood samples were collected and subjected to estimation of serum calcium and alkaline phosphatase level. The results revealed that 200 and 400mg/kg dosages of Solanum leaf extracts showed significantly comparable anti ulcer-activity as that of Rantidine, showing an anti-ulcer activity of the extracts. Thus Solanum nigrum leaves may reduce the acidity of the gastric juice and also prevent the mucosal damage and ulcer...
