Impact of detergents on the protein histochemistry of various cell types of the gill epithelium of rita rita

Abstract

Fish, Rita rita, were exposed to an anionic detergent, dodecylbenzene sodium sulfonate, 6.9 mg per litre of tap water (96-hr LC 50 of the detergent). A gradual decrease in the protein constituents of the major cell types, viz, the epithelial cells and the goblet mucous cells in the epithelium lining the gill arch, gill filament, and club cells present only in the gill arch epithelium has been obseved by using a series of histochemical techniques.
