Background: Intestinal parasitic infections are amongst the most common infections throughout the world. It is estimated that some 3.5 billion people are affected, and that 450 million are ill as a result of these infections, the majority being children. Rationale: Helminthic infestation lead to nutritional deficiency and impaired physical developments which will have negative consequences on cognitive function and learning ability. Objective: To detect prevalence of intestinal protozoa among hospital patient of Atbara teaching hospital. Material and Method: Descriptive, cross sectional study, stool specimens were collected from 30 patients attended to Atbara teaching hospital and examined by wet preparation and concentration techniques. Result: 56% of stool specimens examined were positive for intestinal protozoa. Conclusion: Further studies are required with large sample size and long duration.

Background: Entamoeba coli is intestinal protozoan amoeba which is regarded tell now as commensal amoeba although their adverse symptoms that they may cause in certain patients. Objectives: General objectives: To know the phagocytic activity of Entamoeba coli against microorganisms. Specific objectives: To know the phagocytic activity of Entamoeba coli against microorganisms that inhabit the intestinal tract. Methodology: the study based on data collected from previous studies. Result: Entamoeba coli phagocytosed bacterial flora of the gut, fungi of Sphaerita species and even Giardia lamblia trophozoites. Conclusion: Entamoeba coli is a potent phagocytic microorganism that engulf other microorganisms which may compete it in nutrients.

The aim of present study was to evaluate the antihyperlipedemic activity of Methanol extract of aerial parts of Rhinacanthus nasutus using high fat diet induced hyperlipidemia and Triton X-100 induced hyperlipidemia models in Wister Albino rats. Hyperlipidemia is a disorder of lipid metabolism manifested by elevation of plasma concentrations of the various lipid and lipoprotein functions which is the key risk factor for cardiovascular disorders [CVD]. Rhinacanthus nasutus extract was administered at different dose of 250mg/kg, 500mg/kg to hyperlipidemic rats. Atorvastatin is used as reference standard. The statistical analysis were carried out using one way ANOVA followed by Dunnet t-test. The serum total cholesterol, triglyceride, HDL, VLDL, LDL levels were analyzed. Methanoic aerial part extract of rhinacanthus nasutus. Exhibited significant [p<0.05] effecting reducing the serum cholesterol, lipid levels. The present study clearly demonstrated the anti-hyperlipidemic activity of Rhinacanthus nasutus supporting the traditional claim.
