Abstract
Trichinosis is a worldwide zoonotic disease closely related to cultural and dietary habits caused by a nematode Trichinella spp. The drugs for its prevention and treatment are still not thoroughly defined. Wortmannilactone F was used to value the therapeutic effects on the worm reduction rates, change of the intestinal mucosa, and the host's body's immune activity in this experiment. BALB/c mice were orally fed with 200 infective Trichinella spiralis larvae. Then, T. spiralis-infected mice were treated with wortmannilactone F (50, 100, and 200 mg/kg). The number and morphological analysis of adult worm, the expression of Factor associated suicide (Fas), and the level of SIgA in the mice were investigated. Wortmannilactone F showed dose-dependent anthelmintic effects by causing mortality of worms, obvious damaging effects on mature T. spiralis' surface and their digestive systems, decreasing the expression of mice's intestinal mucosa's Fas protein, and reducing intestinal mucosa's level of SIgA secretions. Wortmannilactone F is expected to be a potential therapeutic drug for trichinellosis treatment.
