Food and nutrients play vital role in normal functioning of the body. The samples selected for this study were Ethanolic extract of Red grape seed, Ethanolic extract of green tea leaves, Commercially available grape seed extract / Isotretinion tablet, green tea extract , Vitamin A and E tablets. The Nutraceutical effects of grape seed extract and green tea extract was analyzed. The antimicrobial activity of all the above samples were studied by disc diffusion method against Pseudomoas spp., Flavobacterium spp, Aeromonas spp., Enterobacteriaceae, E. coli, lactobacillus spp., and staphylococcus spp. The antibiotic tetracycline disc used as a standard. All samples had been found to contain potent antimicrobial activity. The antioxidant activity was measured by DPPH method and compared with vitamin A and vitamin C. Both the prepared and commercially available extracts obtained more antioxidant activity than vitamin A & C. Thus the results showed that the grape seed extract and green tea leaves has antioxidant and antimicrobial...

Background: Diabetes is a group of metabolic disorders that affect the body’s ability to process and use sugar (glucose) for energy. Type 2 diabetes mellitus resulting from the combination of resistance to insulin action and inadequate insulin secretion. The success of long-term maintenance therapy for diabetes depends largely on the patients’ adherence with self-care practices. Objective: The aim of this study was to assess diabetes self-care practices and associated factors among type 2 diabetic patients in Tikur Anbessa Specialized Hospital, Ethiopia. Method: institutional based cross sectional study was employed and 320 study subjects were selected using systematic random sampling technique. And the data was collected using interviewer administered structured questionnaire; data was analyzed and cleaned using SPSS version 16. Scoring method was employed to classify patients’ self-care practice level as adhered or not adhered to self-care practices. Results: Of all respondents 167(52.2%) female. Mean age of the respondents was 55.03±10.7 years with minimum age of 30 and maximum age of 85. The mean duration of diabetes was 12.3±7.6years with...

Glibenclamide is practically insoluble in water and its gastrointestinal absorption is limited by its dissolution rate. Therefore, to enhance the drug dissolution and its hypoglycemic effects, the drug was formulated in different microemulsion systems and in vitro/in vivo evaluated. Microemulsion systems were prepared by Water titration method in which surfactants and cosurfactants (S/CoS) were mixed at different weight ratios of 1:1, 2:1 and 3:1. They were subjected to transmission electron microscopical examination, pH determination and viscosity tests. The solubility of Glibenclamide in different microemulsion systems was determined. Forms 8, 9, 10, 11, 14 and 18 were found to have high Glibenclamide solubility using different oils. Form 11 and 9 showed the highest Glibenclamide release rates of 59.72% and 52.35%, respectively after 6 hours. In-vivo studies were tested using diabetic rats by application of form 11 with n-butanol as cosurfactant transdermally and form 8 with propylene glycol cosurfactant orally and transdermally. The results were compared to the drug suspension as a positive control. It was shown that microemulsion systems gave...

The Diethyl ether fraction of the Methanolic extract of Annona senegalensis (Pers) stem bark was prepared in yield of (0.16%). Preparative Thin Layer Chromatography analysis of the fraction resulted in the identification of two spots with antimicrobial activity. Subsequent GC/MS analysis of these spots resulted in the identification of ten components (spot one) and fourteen components (spot two). The fraction showed significant antimicrobial activity against clinical isolates of E. coli, S. enteriditis and S....

A rapid and simple HPLC method has been developed for the quantification of curcumin in PGPR inoculated curcuma longa plant. Treatment of PGPR such as Pseudomonas fluorescens and Bacillus megaterium improved the content of curcumin in rhizomes sample. The PGPR treated rhizomes were higher in curcumin content than the PGPR untreated plant rhizomes sample. Analysis was performed using a C18 column (250 X 4.6 mm) by isocratic elution with 50mM potassium dihydrogen orthophosphate (pH 3.5): Acetonitrile (40:60) and detection at 420 nm and 340 nm using a photodiode array detector for curcumin respectively. The calibration plot was linear over the range studied (Curcumin: 100 – 3200ng/mL) with a correlation of 0.999. The method was also validated for the precision and recovery. Thus, the method is suitable for routine analysis of curcumin in PGPR inoculated curcuma longa plant sample 1, compared with PGPR uninoculated plant sample...
