机译:Cationic responses of organs and haemolymph of Biomphalaria pfeifferi (Krauss), Biomphalaria glabrata (Say) and Helisoma trivolvis (Say) (Gastropoda: Planorbirdae) to cationic alterations of the medium
The cationic responses of haemolymph, mantle collar, headfoot, gut + digestive diverticulum and ovotestis + albumin gland of three planorbids to cationic changes in the media are explored. Body organs exhibited cationic homeostasis, although attained with difficulty under very low Ca : Mg and Ca : Na ratios. Haemolymph imbalances were obtained at very low calcium concentrations and at very low Ca : Mg and Ca : Na ratios in the medium; this may be linked to competition for Ca2+uptake sites in the epithelium by Mg2+and possibly Na+ions.
