Aim: To comparatively evaluate the antihypertensive efficacy and tolerability of ramipril and telmisartan in stage 1 hypertensive diabetic patients. Material and Methods: This short term, prospective, randomized, interventional, comparative clinical study was conducted amongst 53 patients of stage 1 hypertension with type 2 diabetes (27 ramipril and 26 telmisartan patients), aged 30 years and above. Ramipril was administered 5 mg/day and telmisartan 40 mg/day respectively throughout the study period of 3 months. Blood pressure was measured using mercury sphygmomanometer. Paired and unpaired student t-test was applied. Results: Mean SBP was 153.2 and 154.52 mm Hg and mean DBP 87.6 and 87.57 mm Hg in ramipril and telmisartan group respectively. During follow-up the mean SBP and DBP consistently decreased. At 3 months the mean SBP was 124.72 and 123.83 mm Hg in ramipril and telmisartan group respectively. Similarly, the mean DBP at 3 months was 78.16 and 76.7 mm Hg in ramipril and telmisartan group respectively. Although the lowering of blood pressure (both systolic and diastolic) by ramipril or telmisartan...

Globally, more than 30 % of the onion peels arises at the retail and purchaser levels, of which the post-harvest and dealing out level wastages report for the major share. So, studies on the characterization of unutilized fractions of the onion peels specify their potential candidature for reprocessing. Maximum preservation of these phytochemicals during extraction requires optimised process parameter conditions. A microwave-assisted extraction (MAE) method was considered for extraction of total phenolics, total flavonoids and DPPH scavenging activity from onion peels. The total phenolic capacity (TPC), total flavonoids content (TFC) and antioxidant activity percentage of extracts at optimised MAE conditions. The influence of six main extraction parameters on the extraction was modelled by using a second-order regression equation. The optimal MAE conditions were 210W microwave power, 15min irradiation time and 40 mL/g solvent to material ratio. Under the MAE optimised conditions, the recovery of TPC was 94.34 mg gallic acid equivalent/g dry weight (DW), TFC was 45.61(mg/g) and free radical scavenging activity 92.25%.When bioactive phytochemicals extracted from onion skin...

6-(2-Amino-3,5-substituted phenyl)-1,2,4-triazines were prepared by refluxing semicarbazones or thiosemicarbazones in presence of sodium hydroxide solution. 6-(3,5-Substituted-2-bromophenyl)-1,2,4-triazine derivatives and 6-(3,5-substituted-2-hydroxyphenyl)-1,2,4-triazine derivatives were prepared from 6-(2-amino-3,5-substituted phenyl)-1,2,4-triazine derivatives by sodium nitrite, hydrobromic acid, copper (I) bromide and sodium nitrite, sulfuric acid, respectively. The structures of the synthesized compounds were confirmed on the basis of their elemental analysis and spectral data (FT-IR and H1-NMR). Amongst synthesized compounds, some displayed significantly active profile against the electrically induced seizures at a dose of 30 mg/kg after 0.5 h. At the same dose level, one compound also showed activity after 4.0 h. Two compounds exhibited protection at dose level of 100 mg/kg after 0.5 h. At 4.0 h, two compounds persisted to reveal anti-MES protection at same dose, whereas two other compounds indicated to prevent seizure spread at a higher dose of 300 mg/kg after 4h. One compound displayed protection at 300 mg/kg after 0.5 h. The neurotoxicity screening data revealed that two compounds were exhibited neurotoxicity at a dose level of 300 mg/kg after...

The number of patients with Diabetes mellitus is increasing rapidly both in developed and developing countries around the world. The existing medications especially synthetic drugs often fail to bring back normal glycemic control without complications. Numerous herbal medicines are widely explored as alternative medicine in diabetes. The objective of this work was to evaluate one such herbal extract of Benincasa hispida fruit for its anti-diabetic activity in experimentally induced diabetic rats. The extract at a dose of 200mg/kg/day and 400mg/kg/day was administered to streptozotocin induced diabetic animals for 15 consecutive days. Blood glucose levels, lipid profiles and body weight were measured for the evaluation of its anti-diabetic effect. The results of the study at both low and high dose of extract showed significant (p<0.01) decrease in blood glucose levels in diabetic rats. In addition, both the dose of extract also showed significant (p<0.05) decrease in serum triglyceride, VLDL levels, and an increase in HDL levels, though not significant. Only high dose of extract and glibenclamide treated group showed significant...

Novel 1- Phenyl 1-H-Pyrazolo[3,4-d]Pyrimidine Derivatives were synthesized from the key intermediate chloro derivative (1).The conversion of chloro derivative(1) into 1,2,4 triazoles, 1,3,4 thiadiazoles and thiazoles was accomplished with the intermediacy of the ester(2) and hydrazide (3). Moreover triazole ring was annelated to the pyrazolopyrmidine core in two step reaction involving reaction with acid hydrazides followed by intramolecular cyclization in boiling glacial acetic acid Majority of the synthesized compounds showed variable antimicrobial activity on the hand tricyclic compounds(9a-b) were deprived from any antimicrobial activity against the tested micro-organisms. The hydrazine carbothioamide derivative (4) and 1,3,4 thiadiazole derivative (6) showed antimicrobial activity against Streptococcus pneumoniae and Bacillis subtilis comparable to ampicillin and a moderate antifungal activity against Asp. Fumigates and C....
