The animals were randomly divided into five groups. The first-four groups of 15 rats were further divided into 3 subgroups of 5 rats. The drug was administered orally at sub-optimal, therapeutic, and high doses of 25, 50 and 75 mg/kg bw,respectively to the rats for 1 day, 2 days and 3 days. Blood samples were collected by cardio-puncture from the rats for hematology at the end of each phase. The last group served as control,and they were given waterad libitum.Results:Artemether caused significant reduction(P<0.05)of the hematological profile of the animals in a dose dependent manner. Discontinuation of the drug use however showed gradual recovery of the depressed indices of the blood parameters.Conclusions:The results suggest that artemether can induce reversible changes in hematological profiles of rats by extension man. This can probably aggravate anemia when artemether is administered to malaria patients. Hence, the study supports the use of the drug with cautione specially in patients prone to anemic tendencies.展开更多

The inverse relation of H. pylori prevalence and the increase in allergies, as reported from epidemiological studies, has stimulated research for elucidating potential underlying pathophysiological mechanisms. Although H. pylori is most frequently acquired during childhood in both developed and developing countries, clinicians are less familiar with the pediatric literature in the field. A better understanding of the H. pylori disease spectrum in childhood should lead to clearer recommendations about testing for and treating H. pylori infection in children who are more likely to develop clinical sequelae. A further clinical challenge is whether the progressive decrease of H. pylori in thelast decades, abetted by modern clinical practices, may have other health consequences.展开更多
