Abstract

Pathomorphological changes in the skin was noticed under the scanning electron microscope in fish fingerlings (Cirrhina mrigala) exposed to 0.005 ppm (25% of the LC50) concentration to linear alkyl benzene sulfonate. The epithelial cells present in the epidermis of the skin were found to secrete more mucus with linear alkyl benzene sulfonate (LAS) than did controls. The presence or deposition of mucus on the surface of skin indicated likely molecular interaction between constituents of mucus and LAS.

摘要

在扫描电子显微镜下观察到，暴露于0.005 ppm（半数致死浓度的25%）直链烷基苯磺酸盐的鲮鱼幼鱼的皮肤出现了病理形态学变化。研究发现，与对照组相比，皮肤表皮中的上皮细胞在接触直链烷基苯磺酸盐（LAS）时会分泌更多黏液。皮肤表面黏液的存在或沉积表明黏液成分与LAS之间可能存在分子相互作用。
