Various locally available vegetables were screened for the enzyme peroxidase. The screening was performed mainly on daikon, cabbage, cauliflower; tomato and sweet potato etc. The juices of these vegetables were extracted and subjected to ammonium sulphate precipitation followed by dialysis to remove any adhere salts. The partially purified enzymes were then subjected to peroxidase assay. All the extracts from vegetables showed the presence of appreciable amount of peroxidase. In order to quantify, kinetic measurements of all the partially purified enzymes were performed using hydrogen peroxide as substrate and guaiacol (ortho-methoxy phenol) as color forming dye. The enzymatic activities of daikon, cabbage, cauliflower, sweet potato and tomato peroxidase having optical densities of 0.056, 0.139, 0.226, 0.139 and 0.089 at 280 nm were found to be 2.2898 U/ml, 3.4381U/ml, 1.1675 U/ml, 0.3741 U/ml and 0.1901 U/ml respectively. In order to compare the above result, the data have been normalized with respect to optical densities of cabbage. Thus, the partially purified enzyme having a optical density of 0.139 shows the peroxidase activity...

The present study was carried out to determine the presence of phytocomponents in the aerial parts of Cleome burmanni using Gas Chromatography- Mass Spectrometry (GC-MS) analysis. The mass spectrum of the crude chloroform extract was compared with the available library sources (NIST08 LIB, WILEY8 LIB). Sixteen components were identified. Sterols, terpenoids and hydrocarbons were the most prominent. The major components detected were 24(s)- Ethyl-3- alpha, 5-alpha-cyclocholest-22 (E)-en-6-one (19.29%), Delta-4-Sitosterol-3-one (14.75%), Cholest-4-en-3-one (12.35%), Stigmasta-5, 23-Dien-3-ol, (3-beta) (12.17%), Neophytadiene (6.83%), Hexatriacontane (6.22%), 1-alanine, N-(3-fluorobenzoyl) – undec-10-enyl ester (5.96%), phytol (5.67%), tetracontane (4.30%), 1,2- benzenedicarboxylic acid (3.25%). The other components were present in minute...

Background: Maternal mortality is one of the indicators in the millennium development goal that is raising concern in achieving the set target of reducing the rate by three-fourth by 2015. Women who die due to pregnancy-related causes are in the prime of their lives and are responsible for the health and well-being of their families. Objective: To assess patterns of maternal mortality and associated factors: at public hospitals in Tigray region, Ethiopia, 2010-2012. Methods: A hospital based case control study was done from May 2012 to December 2012 at public hospitals found in Tigray regional state. Cases were mothes who died in hospital between July, 2010 to June, 2012 and controls were mothers who gave birth in the same hospital during same period. Simple random sampling method was used to select the case and controls. A ratio of four controls to one case was considered to assure sufficient sample size. Data were entered, cleared and analyzed using SPSS window 16. Bivariate analysis was used to determine an association between...

In the present study an attempt has been made to prepare fast dissolving tablets of Sumatriptan Succinate to improve dissolution rate of the drug in oral cavity & hence better patient’s compliance & effective therapy. Sumatriptan Succinate is a 5-HT1D (5-hydroxy tryptamine 1D) receptor agonist, used in the treatment of migraine and cluster headache. It has low bioavailability due to its first pass metabolism. Hence the main objective of the study was to formulate fast dissolving tablets of Sumatriptan succinate to achieve a better dissolution rate and further improving the bioavailability of the drug. Fast dissolving Sumatriptan succinate was prepared using superdisintegrants Crospovidone, Croscarmellose Sodium, and Preglatinised Starch using the direct compression method. The tablets prepared were evaluated for Thickness, Uniformity of weight, Drug content, Hardness, Friability, Wetting time, in vitro and in vivo disintegration time, in vitro drug release. The formulation F3 containing Crospovidone (8%) was found to give the best result since it showed enhanced dissolution, which leads to improved bioavailability, improved effectiveness and hence better patient...

Background: Rational drug use in pregnancy requires the benefits and potential risk associated with the use of the drug. The adverse effect of drugs on the fetus varies temporarily with time. The fetus susceptibility to injury depends on its period of development of different organs have different critical periods through the span from gestational day 15 to day 60 is critical for many organs. Objective: To assess the pattern of drug use among pregnant women in Adama Referral Hospital, Oromia region, Ethiopia. Methods: All drug prescriptions of pregnant women prescribed from December 1, 2011 to May 30 2011 were reviewed retrospectively using structured data collection format. Result: A total of 381 pregnant women prescriptions were included in the study. The average maternal age in the study was 26.74 years. A total of 176(24.44%), 336(46.66%) and 208(28.88%) drugs with an average 2.2, 1.13 and 1.83 per pregnant women were used in first, second and third trimesters respectively. Minerals and vitamins 209(29%) were the most frequently prescribed drugs followed by Antibiotics...
