The present study was carried out to find out the gastroprotective effects of the leaves extracts of Dypsis lutescens (H.Wendl.) and Caryota Urens (L.) in aspirin-induced gastric ulcer in rats. The ethanolic and aqueous extracts were prepared from the leaves of Dypsis lutescens and Caryota Urens and were used for this study. All procured animals were divided into seven groups. Each group contain n = 6, all groups except the normal control treated with aspirin 150 mg/kg oral. Group, I served as the normal control group which received normal saline, group II served as negative control and group III as standard group receiving 20 mg/kg omeprazole and 4th to 7th groups treated with leaves extracts of Dypsis lutescens and Caryota urens respectively. Treatment was given to group II to group VII rats in every 24 h for seven days. After 24 h fasting, on the 8th-day stomach contents were aspirated under anaesthetic condition to check free and total acidity. Stomachs were opened in all sacrificed animals along the greater curvature to estimate ulcer index, percentage protection and histopathology studies. The results of the present study revealed that the severity of aspirin-induced ulceration was significantly (P < 0.05) decreased in Dypsis lutescens extracts treated groups in comparison with the control and Caryota urens treated groups. It was observed that the free and total acidity significantly decreased in the aqueous extract of Dypsis lutescens treated group when compared with the negative control and Caryota urens treated groups.
The effects of polyherbal formulations were studied in the streptozotocin-nicotinamide (STZ-NA) induced diabetes rat model. The present study was undertaken to assess the effects of polyherbal formulations on the blood sugar level (BSL) as well as blood lipid level(BLL) of STZ-NA diabetic rats. The leaves of Moringa oleifera and roots of Raphanus raphanistrum were used for the study due to the presence of various phytoconstituents such as alkaloids, saponins, tannins, steroids, phenolic acids, flavonoids. Three polyherbal formulations were prepared from different portions of leaves of Moringa oleifera and roots of Raphanus raphanistrum and titled PHF-I, PHF-II and PHF-III. Diabetes in experimental animals was induced by STZ injection intraperitoneally (i. p) after 30 min of Nicotinamide injection i. p in all animal groups except normal control group animals. Group, I served as normal control received no treatment. Group II served as negative control received streptozotocin-nicotinamide. Group III rats were treated with Metformin, Group IV, Group V and Group VI rats treated with PHF-I, PHF-II and PHF-III respectively. Physical parameters (body weight, feed and water intake), Biochemical parameters (Blood Glucose, Serum Insulin, Serum C-Peptide Level, Serum Leptin, Serum Total cholesterol, Serum Triglycerides, LDL and VLDL) were measured on 0th, 14th and 28th day. The study results and histopathology of the pancreas indicate that oral administration of polyherbal formulation- II proved as a more effective, safe anti-diabetic agent in comparison to Polyherbal formulation I and III by Decrease in body weight, fasting blood glucose, serum glucose level. Increase in serum insulin level, serum C-peptide with a significant decrease in blood serum lipid level.
