- Abstract
- We evaluated the level of toxicity by LC50 and investigated the mechanism of brain impairment and GFAP expression
by light and fluorescence microscopes in the pale chub, Zacco platypus, treated with fenvalerate. Survival rate was
decreased according to the rise of fenvalerate concentration, and LC50 concentration was 27.79 μg/L. Apoptosis was
increased according to the rise of fenvalerate concentration by TUNEL assay which determine apoptotic cell death population.
Also, GFAP expression was increased in the periventricular zone. These results suggest that apoptosis might be a
major mechanism to brain impairment of the pale chub by fenvalrerate. Increased GFAP expression in the periventricular
zone would be an index of brain impairment. Taken together, this study might contribute to reveal the pathological
mechanism of fish brain impairment by insecticide of pyrethroid, and to be an useful basic data for preservation of aquatic
ecosystem.
