Sex Differences in Hepatic Lipids of Toxaphene-Exposed Juvenile Yellowtail Flounder (Pleuronectes ferrugineus Storer)

摘要

Histochemical and biochemical effects of Toxaphene on liver were investigated in laboratory-bred female and male juvenile yellowtail flounder (Pleuronectes ferrugineus). Fish were fed uncontaminated food, or food contaminated with hexane (the solvent for Toxaphene) or with one of two concentrations of Toxaphene (0.02 or 0.2 μg/g fish/day) for 2 weeks. Males were more advanced in sexual maturity than females, although all were from the same year-class (0~+). Liver tissue examined histochemically (Sudan black B, oil red O) revealed that Toxaphene affected storage of total and neutral lipids according to sex and dose.
