通过对12尾雌性中华鲟(Acipenser sinensis)背部肌肉注射不同浓度(0、0．1、0．2、0．4 mg/kg·BW)17-β雌二醇( estradiol),并在0、60、120和180 d尾部静脉采血,测定血清中钙( Ca2+)、雌二醇( E2)、睾酮( T)、白蛋白( ALB)、卵黄蛋白原( VTG)、谷丙转氨酶( ALT)、碱性磷酸酶( ALP)以及胆碱酯酶( CHE)的含量。结果显示,注射雌二醇后, Ca2+和VTG含量均先上升后下降, E2和ALP含量不断上升, T和CHE则含量不断下降。 ALT和ALB含量上下波动。此结果表明,雌二醇对养殖中华鲟卵巢发育具有一定的促进作用,但浓度过高会对其肝脏造成损伤,0．1 mg/kg·BW是较为适宜的浓度。%In this study, 12 female Acipenser sinensis were injected of 17-β estradiol (0, 0. 1, 0. 2 and 0. 4 mg/kg· BW) in back muscle and blood was collected from the fish tail at 0, 60, 120 and 180 days. The contents of serum calci-um ( Ca2+) , estradiol ( E2 ) , testosterone ( T ) , albumin ( ALB ) , vitellogenin ( VTG ) , alanine aminotransferase (ALT), alkaline phosphatase (ALP) and cholinesterase(CHE) were examined at 0, 60, 120 and 180 days respectively. Results showed that the concentrations of both Ca2+ and VTG increased firstly and then decreased. Both E2 and ALP in-creased continuously, while both T and CHE decreased. The changes of concentrations of both ALT and ALB were fluctu-ant. Results implied that E2 could promote the ovaries of cultured Chinese sturgeon, while high concentrations could result in injury to the liver.
