Abstract:
Objective To explore the therapeutic effect of artemether and artesunate on adult Schistosoma mansoni in experimental mice.Methods The mice were administered intragastrically with artemether or artesunate 46 days after being infected with cercariae of S.mansoni subcutaneously. On Day 1,a dose of 400, 300, 200 mg/kg of artemether or artesunate was administered to the mice. From Day 2 to Day 7, a half above dose was administered. On Day 7, the single-dose groups were administered with artemether or artesunate at the dose of 1600, 1200, 800 mg/kg, meanwhile, an infected group of mice was served as control, untreated. Results With 7-day therapy of artemether at the dosage of 1600, 1200, 800 mg/kg, the worm reduction rates were 53%, 49% and 53%, respectively, and female worm reduction rates were from 78%-82%, compared with the control group.The therapeutic effects of artemether on single-dose groups were similar. The worm reduction rates, with 7-day therapy of artemether at the dosage of 1600, 1200, 800 mg/kg , were 16%,37% and 49%, respectively, compared with the control group. Conclusion The efficacy of therapy with artemether and artesunate on S.mansoni infection mice were relatively well. Concerning the therapeutic effect and toxicity, artemether is slightly better than artesunate.
