The study is aimed at development of physicochemical parameters and to investigate the active principle present in Tridax procumbens Linn. Tridax procumbens Linn. (Asteraceae) commonly known as Coat Buttons is an important plant used against various disorders in indigenous system of medicine such as Wound-Healing, Hepatoprotective, Anti-Inflammatory, Anti-diabetic and Immunomodulatory activities. However its functional properties and the underlying mechanism of action have not been clearly defined, the present study was undertaken to evaluate anthelmintic activity of methanol extract of leaves of Tridax procumbens L. against Pheretima posthuma (earthworm). Various concentrations (10, 20, 30mg/ml) of methanolic extract were evaluated in the bioassay involving determination of time of paralysis (P) and time of death (D) of the worms. Albendazole was used as standard anthelmintic drug and distilled water was used as control. The results of present study indicated that the methanolic extract of leaves of Tridax procumbens showes significantly dose depending pharmacological...

Ziziphus mauritiana contains fructose, galactose, malonic acid, malic acid, p-hydroxybenzoic acid, caffeic acid, ferulic acid and vanillic acid .The antioxidant activities of the plant extract and pure compounds were assessed by Reduction of NBT (Nitro Blue Terazolium) and Nitric Oxide Radical Inhibition activity method. The five successive extract (benzene, petroleum ether, chloroform, methanol and aqueous extract) of Ziziphus mauritiana Leaves and one standard (Ascorbic acid) were tested for in-vitro antioxidant activity. The result was expressed as IC50 values and percentage inhibition at different...

Background: Multi-drug resistance tuberculosis (MDR-TB) is an increasing global problem. The extent and burden of MDR-TB varies significantly from country to country. Survival of MDR-TB treatment is not described in Ethiopia. Therefore, examining a cohort who received second-line therapy for MDR-TB to determine overall survival has a great importance. Objectives: To assess survival and predictors of mortality among patients under MDR-TB treatment in Ethiopia: St Peter’s specialized TB Hospital, Addis Ababa, Ethiopia. Methods: A retrospective analysis of records was conducted from Oct, 2011 – May, 2012 among cohorts of MDR-TB patients in St. Peter’s specialized TB hospital that starts treatment from February 2009. Data were collected using checklist from 188 patients’ record that is determined and analyzed using the STATA Statistical package, Version 11.0. Risk was estimated for the entire follow-up time corresponding to each event occurrence using Kaplan-Meier method and the covariates are fitted to Cox proportional hazard regression model. Result: The 188 patients were followed for a total of 79,600 person-days. Median follow up time was 466.5 days...

Method: Institution based cross-sectional study was conducted on patients attending ART clinics for persons living with HIV/AIDS (PLWHA) at Adigrat, Mekelle and Maichew Hospitals in Tigray region. Sample size was calculated using Epi info statcalc and 269 PLWHA were included in the study. The patients were interviewed by psychiatric nurses using the 21 item Hamilton’s depression scale Questionnaire. Data was analyzed using the Statistical Package for the Social Sciences (SPSS, version 19.0). Levels of depression were calculated among various subgroups of patients, according to the Hamilton’s depression scale questionnaire. The possible associations of the presence and severity of depression with socio-demographic variables was explored using appropriate parametric and non-parametric tests. Specifically, the odds square and logistic regression was used in the exploration of associations; ethical clearance was obtained from Mekelle University College of health sciences. Result: Out of 269 total participants, 142(52%) were females, 213...
