영문 초록

This study was performed to observe histological changes of the equilateral venus, Gomphina veneriformis exposed to cadmium. Mantle of the equilateral venus showed desertion of cilia in the early stage of exposure to cadmium, separation of fibromuscular layer and outer epidermal layer, extension of hemolymph sinus, disappearance of striated border and desertion of epithelium. In the gill, it was showed extension of hemolymph sinus in the early stage of exposure, increase of acid mucous cell and decrease of neutral mucous cell, desertion of cilia, separation of filaments, increase of acid mucous cell and disappearance of epidermal layer. Labial palp showed extension of hemolymph sinus, desertion of cilia, decrease of acid mucous cell, desertion of epithelium and disappearance of epidermal layer. Siphon was observed extension of hemolymph sinus in the early stage of exposure, activation of mucous cell, cutted muscle fiber bundle and disappearance of epidermal layer after desertion of epithelium. The equilateral venus just before death was impossible to be recovered to normal condition in mantle cavity organs, the longer of exposure time and the higher of concentration of cadmium. Above mentioned, the functional impediment was considered to occur by the histopathological conditions.
