J Ultrastruct paramphistomes from Nile fish in Egypt: an ultrastructural study. For SEM studies, the control and treated parasites were washed in phosphate buffer saline pH 7.

They were washed using distilled water and dehydrated through graded alcohol series. Photomicrographs were taken at various magnifications with an Exakta exa 1 camera, using Nova FP4 type film. Histopathological changes of AcPE-treated parasites were observed using light and transmission electron microscopy TEM. For light microscopic LM studies, the control and treated parasites were washed in physiological saline and fixed in Bouin's fixative for 12 h.

These fixed flukes were washed in distilled water and dehydrated through graded alcohol series, cleared in xylene, and embedded in paraffin wax. Sections were cut at 5 mm thickness and stained in hematoxylin and eosin and were observed under binocular compound microscope for various cellular details. Double fixation gives stability during dehydration, embedding, and also during electron bombardment.

The specimens were dehydrated by ascending graded alcohol series and cleared by propylene oxide. One micron thick sections were cut, before trimming of the blocks for ultramicrotomy.

This helps for marking the areas of interest. Further, ultrathin sections 1 nm were cut using leica ultramicrotome. These ultrathin sections were mounted on the copper grid and stained with double stain, metallic uranyl acetate, and Reynold's solution.In the present investigation, the anthelmintic efficacy of bark of Prosopis cineraria was assessed based on its effect on the motility and on the enzyme acetylcholinesterase AChE of Cotylophoron cotylophorum.
