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 .
