| Nonyphenol (NP) used actively as non-ionic surfactant is classified as one of most potent endocrine disrupting chemicals. Effects of NP on mixed function oxygenase (MFO) system in rockfish (Sebastes schlegeli) were investigated for seven days after intraperitoneal injection (10 and 25 mg $kg^{-1}$). Hepatosomatic index (BSI) of fishes exposed to NP of 25 mg $kg^{-1}$ was significantly reduced compared to those in control group. NP exposure enhanced cytochrome P450 levels in the fish liver, while 7 ethoxyresorufin-O-deethylase (EROD) activity was inhibited. NP exposure levels in this study were much higher than those found in the coastal environment of Korea. Effects on HSI and liver MFO system, which is involved in steroid hormone metabolism, imply that W may influence on reproduction of fish by not only hormone receptor mediated response but also through effects on the MFO system. |
