Evaluation of Antischistosomal Activities of Crude Aqueous Extracts of , , and against in Hamsters.

Schistosomiasis is a neglected disease, as the World Health Organization classified it in the second category after malaria. World Health Organization approved praziquantel (PZQ) as the only chemotherapy to treat schistosomiasis. Over the years, some problems have arisen with PZQ, as it showed poor efficacy in the early stages of infection as well as the emergence of some resistance to it. In searching for new alternative drugs to treat schistosomiasis, the researchers intensified their efforts to find a new drug. The present study focuses on evaluating the effect of three plant extracts , , and at different doses of 31.25, 62.5, 125, 250, and, 500 g/ml; study was accomplished on the adult worms. The results declared that the concentration of 500, 250, and 125 of was more effective on adult worms, and the same concentrations of gave less effect on the adult worms than the previous plant. study was accomplished on the hamster's tissue after exposing it to doses of the plants' extracts with different concentrations; it showed the presence of calcifications and damage to the worm eggs in the liver and spleen, as well as reducing the size of granulomas. After conducting many confirmatory studies extract can be used as an effective and safe treatment for disease.
