Effect of oral treatment of Sida pilosa aqueous extract on the liver (I) and ileum (II) histology of Schistosoma mansoni-infected mice. Arrows: indicate inflammatory cells infiltration; F-Gr: fibrotic granuloma; Gr: granuloma. In uninfected-untreated mice, liver (I-a) and ileum sections (II-a) showed normal structure. Multiple and voluminous granulomas surrounded with fibrous tissue were present in the liver sections of infected-untreated mice (I-b). The mucosa of their ileum contains nonfibrotic granulomas and the muscular layer was thickened (II-b). In the liver (I-c) and ileum sections (II-c) of SpAE-treated mice, scare and small granulomas were detected; while in PZQ-treated mice, liver (I-d) and ileum sections (II-d) were nearly free of granulomas
