对罗氏沼虾（Ｍａｃｒｏｂｒａｃｈｉｕｍｒｏｓｅｎｂｅｒｇｉｉ）成虾六种组织的谷丙转氨酶（ＧＰＴ）和谷草转氨酶（ＧＯＴ）活性正常值作了测定，其中心脏和绿腺的ＧＰＴ和ＧＯＴ活性较高，鳃和肝胰脏次之，卵巢和肌肉较低。不同镉离子浓度（０．３７、０．７４和１．４８×１０－６）对罗氏沼虾的急性中毒试验表明，受水中０．７４和１．４８×１０－６Ｃｄ２＋影响，心脏、鳃和肝胰脏的ＧＰＴ和ＧＯＴ活性显著降低；绿腺的ＧＰＴ和ＧＯＴ活性在０．７４×１０－６组显著升高。组织学观察显示，Ｃｄ２＋中毒引起鳃丝增粗，鳃丝血腔扩大；肝小管严重萎缩，肝细胞解体；绿腺细胞解体，迷路结构消失。
The activities of GPT and GOT in six tissues of adult Macrobrachium rosenbergii were determined. The activities of GPT and GOT in the heart and gland were higher than those in the gill and hepatopancreas Second, lower ovary and muscle. Acute poisoning of Macrobrachium rosenbergii at different concentrations of cadmium (0.37, 0.74 and 1.48 × 10-6) showed that under the influence of 0.74 and 1.48 × 10-6 Cd2 + in water, heart, gill and The activities of GPT and GOT in liver and pancreas decreased significantly. The activities of GPT and GOT in gland were significantly increased in 0.74 × 10-6 group. Histological observation showed that Cd2 + poisoning caused the gill filaments to thicken, the gill filament blood cavity enlarged, the hepatic duct severely atrophied and the hepatocytes disintegrated. The gland cells disintegrated and the lost structure disappeared.
