Introduction: – The nutritionalstatusand health outcome of older persons in low-income countries including Ethiopia is inadequately documented. Logistical difficulties and the absence of simple, easy-to-handle assessment instruments and data-collection problems in this environment are evident. As a result, nutritional data for older adults are inadequate. The scanty, mainly hospital-based, data that are available are not comprehensive, and they fail to incorporate essential indicators of nutritional status. Objectives: – the aim of this study was to assess the nutrition status and major risk factors of hypertension among adults In Tigray, Ethiopia. Methods: – A case control study design was used to assess the nutritional status and major risk factors of hypertension among adults in Tigray, Ethiopia. The study was conducted from Dec, 2010 to October, 2011. The study populations were both adult men and women (age >=40) residing in Tigray region. The study was conducted in three randomly selected hospitals. Sample size was calculated using Epi info statcalc, a structured questionnaire was used. The data was handled confidentially, and entered...

Couroupita guianensis (Lecythidaceae) , is a medicinal plant which is endowed with curative properties including anti- fungal, anti – biotic, anti – septic, analgesic, anti-malaria, stomach – ache, tooth – ache, scabies, gastritis, bleeding piles, dysentry and scorpion poison. The study deals with the preliminary phytochemical screening of the stem of Couroupita guianensis with various extracts such as petroleum ether, benzene, ethanol and water. This includes the powder characteristics studies, fluorescence studies and thin layer chromotgraphic studies of the stem powder. The qualitative analysis of some secondary metabolites, to ascertain medicinal claims of this widely used medicinal plant. The results showed that the moderate presence of alkaloids, flavonoids, steroids, amino acids, phenols and...

Clinacanthus nutans Lindau (Family: Acanthaceae) has attracted public interest recently due to its high medicinal values for the treatment of cancer, inflammation and various skin problems. This study was aimed to determine the oral LD50 value of the methanol leaves extract of C. nutans and identify the targeted organs in mice. This acute oral toxicity study was conducted in accordance to OECD 423 guidelines by using male Swiss albino mice weighing 25-35 g. First group was served as control group which received distilled water (vehicle) while second and third group were orally treated with single daily dose of 0.9 g/kg and 1.8 g/kg of methanol leaves extract of C. nutans, respectively. All the animals were closely observed for 14 days. Body weight for each mouse was recorded at day-0, day-3, day-7 and day-14. Relative organ weights for liver, kidney, spleen, lung and heart were also determined. All the results were presented as mean ± standard deviation and analyzed using Dunnett’s Test after ANOVA test. From the results obtained, no...

The anti-ulcer activity of aqueous extract of Annona squamosa leaves was investigated on a indomethacin induced ulcer models in wistar rats. In model the common parameter determined was ulcer-index. aqueous extract of dosage 175, 350 mg/kg p.o produced significant inhibition of gastric lesions induced by indomethacin induced ulcers. The extract 175mg/kg & 350mg/kg showed significant (p<0.01) reduction in gastric volume, free acidity and ulcer index as compared to control. This present study indicate that Annona squamosa leaves extract have potential anti ulcer activity. This results may further suggests that aqueous extract was found to posses antiulcerogenic as well as ulcer healing property,which might be anti secretory...

The present study was designed to investigate the antidiabetic potential of different extracts of Berberis aristata bark, in alloxan induced diabetic male wister albino rats (150-250g), Diabetes was confirmed after 5 days of single intraperitoneally injection of alloxan (140 mg/kg of body wt.) in 12 hours previously fasted rats. Petroleum ether extract of Berberis aristata (PEBA) (100 & 400 mg/kg, body wt.) & Ethanolic extract of Berberis aristata (EEBA) (100 & 400 mg/kg, body wt.) and the standard drug glibenclamide (10 mg/kg, body wt.) were given orally in 0.5% Tween 80 after 5 days of alloxan treatment daily for 20 days, except the normal and diabetic control group (n=6). Blood was collected from the retro orbital sinus of the rats for glucose, total cholesterol and triglyceride level determination on 1st, 5th, 10th and 20th days. PEBA (100 & 400 mg/kg, body wt.) showed significant reduction in blood glucose level (266.3 ± 0.9700 to 118.1 ± 0.9375mg/dl & 271.3 ± 0.6983 to 111.6 ± 0.8072 mg/dl, respectively), total cholesterol (92.40±0.7711mg/dl...
