Intestinal parasitosis and shigellosis among diarrheal patients in Gondar teaching hospital, northwest Ethiopia.

Background: Diarrheal diseases are the major causes of morbidity and mortality in developing world. Understanding the etiologic agents of diarrheal diseases and their association with socio-demographic characteristics of patients would help to design better preventive measures. Thus, this study was aimed to determine the prevalence of intestinal parasites and enteropathogenic bacteria in diarrheic patients.

Experiences with dissection courses in human anatomy: a comparison between Germany and Ethiopia.

Dissection courses in human anatomy are laborious, and new teaching tools have become available. Therefore, some universities intend to reduce the dissection course. Furthermore, little is known about dissection courses in African universities.

Treatment outcome of tuberculosis patients at Gondar University Teaching Hospital, Northwest Ethiopia. A five--year retrospective study.

Keratinocytes as depository of ammonium-inducible glutamine synthetase: age- and anatomy-dependent distribution in human and rat skin.

In inner organs, glutamine contributes to proliferation, detoxification and establishment of a mechanical barrier, i.e., functions essential for skin, as well.

Effect of fatty acids on expression of endothelial leukocyte adhesion molecules.

Background: With respect to linoleic acid both beneficial and proatherogenic effects have been described. However, the effect on expression of cell adhesion molecules on human coronary artery endothelial cells (HCAEC) is not yet established. The aim of the experiments was to evaluate the influence of linoleic acid in comparison with palmitic acid regarding the cytokine-induced expression of endothelial leukocyte adhesion molecules (intercellular cell adhesion molecule-1 ICAM-1, vascular cell adhesion molecule-1 VCAM-1, E-selectin).
