RESUMEN
This work investigated the molluscicidal potency of dried Capparis spinosa and Acacia arabica leaves on some selected biochemical parameters of Biomphalaria alexandrina, in order to render them, physiologically, unsuitable for S. mansoni infection or at least disturb the lifecycle of the parasite within its respective snail host. The effect of the two plants on lactate dehydrogenase [LDH], 5'-nucleotidase, acid phosphatase [AP], aspartate and alanine aminotransferases [AST and ALT], alkaline phosphatase [ALP] and glucose content were studied. This work was extended to evaluate the effect of these two plants on protein profile as well as total protein [TP] content of snail's in hemolymph after 24 hours and 1 week of snails plants feeding. The study revealed that both plants induced a marked alteration in all measured parameters, where LC50 of C. spinosa after feeding at one week showed the most potent effect
