E ffe ct of aluminum (al) on the plasma vite llogenin (VTG) , alkaline-labile phosphorus (ALP P ) , Calcium (Ca) , glutamate pyruvate transaminase (GP T) and hepatosomatic index (H SI ) we re examined in the e stradiol-17β (E 2)-administe red immature rockfish, Sebaste s schlege li. F ish we re intrape r itone ally inje cted with E 2 (5 ㎎/㎏ body we ight (B .W.) ) and/ or Al (0, 0.1, 1, 5 and 10 ㎎/㎏ B .W.) and then plasma we re extracted at 7 days. Thick VTG band was de te cted at a mole cularwe ight position of about 170 kD a in SD S-P AGE using the plasma of E 2-administe red rockfish. This band was reduced by the administration of Al to rockfish. Al reduced the concentrations of ALP P and Ca in a concentration-dependent way and a significant reduction occur red at Al concentrations gre ate r than 5 ㎎/㎏ and 10 ㎎/㎏, re spe ctive ly. The concentration of GP T was incre ased in concentration-dependent way at all the group of Al-administe red rockfish. H SI was reduced in a concentration-dependent way. The se re sults sugge st that Al inte r fe re with E 2-induced vite llogene sis by be ing toxic to hepatocyte .

n re cent ye ars, remarkable conce rn has be en eme rged ove r endocr ine disrupting chemicals (E D Cs) which mimic the e ffe cts of the ste roid hormone and modulate the endocr ine functions of human and wildlife . The biodegradation products of sur factants such as nonylphenol (N P ) have be en regarded as E D Cs. H oweve r , only few studie s have be en car r ied out to inve stigate the e ffe ct of E D Cs on vite llogene sis in mar ine fish. The pre sent study was unde r taken to the e ffe cts of 4-N P on the vite llogene sis of juvenile rockfish, Sebaste s schlege li. J uvenile rockfish we ighing about 50g we re intrape r itone ally inje cted with e stradiol-17β (E 2, 5㎎/㎏ body we ight) or 4-N P in 70% e thanol twice at 3-day inte rvals and blood sampling we re extracted from the fish at 7 days afte r the last inje ction. I ntense VTG bands we re de te cted at mole cular we ight position of about 170kD a in all the plasma of 4-N P -administrated fish as that of E 2-administe red fish. P lasma ALP P , Ca and GP T concentrations we re also incre ased in all the group of 4-N P -administe red fish. The addition of 4-N P to the we lls inhibited the binding activity E 2 to E R in a conve rse sigmoid fashion. The se re sults sugge sted that 4-N P induced VTG synthe sis by the binding affinity 4-N P to E R and acted on E D Cs in the juvenile rockfish
