镉对非洲鲫鱼血、胆、肝、肾乳酸脱氢酶的影响

中国科学院海洋研究所
摘要:
非洲鲫鱼被饲养在镉浓度1ppm、盐度33‰、温度20℃左右的海水中40天。用镉处理的非洲鲫鱼,其血、胆、肝和肾脏的LDH同功酶电泳图谱的着色深度比对照组淡得多,LDH的相对活性亦显著地降低了。血液降低21％,胆汁降低55％,肝脏降低59％,肾脏降低18％。上述结果表明:重全属镉可明显地抑制非洲鲫鱼血、胆、肝和肾的LDH的酶活力。

THE EFFECT OF CADMIUM ON THE ELECTROPHORETIC PATTERNS OF LDH ISOZYME AND THE ACTIVITY OFLDH IN THE BLOOD, BILE LIVER AND KIDNEY OF TILAPIA MOSSAMBICA
Abstract:
Tilapia mossambica were raised in seawater containing Cd in the concentration of 1.0 ppm for forty days. The salinity of the seawater was about 33‰, temperatute about 20℃. Wish the Cd treatment, the electrophoretic patterns of LDH isozyme of the blood, bile, liver and kidney were stained more lightly on the compared with control group, indicating that the effective concentration of LDH isozyme was lowered. Because of the effect of Cd, the relative activity of the LDH was reduced distinctly, the blood by 21%, bile by 55%, liver by 59%, and kidney by 18%. The results indicate that the heavy metal Cadmium can inhibit distinctly the LDH activity of the blood, bile, liver and kidney of T. mossambica.
