| 摘 要： | 为探讨金属硫蛋白（ＭＴ）在运动提高机体自我贩作用，本文实验观察了游泳运动对大鼠心、肝、肺、脑、血管、因浆和骨骼肌等组织金属硫蛋白含量的影响。结果表明耐力训练组大鼠心、肝、肺和骨骼组织金属硫蛋白含量较政党对照组明显降低１３－３４％（Ｐ〈０．０５）；急性力竭运动组大鼠心、肝、脑、肺和骨骼肌组织其含量较正常对照则明显或高２１－７５％（Ｐ〈０．０５）；但两组大鼠血管和血浆ＭＴ含量变化与对照组大鼠要比无统计

| Abstract: | To understand physiological role of metallothionein (MT) during exercise, MT levels in liver, brain, heart, lung, blood vessel, skeletal muscle and serum were observed in rats. The results showed that the levels of MT were decreased by 13-34% in lung, liver, heart and skeletal muscle of rats trained by swimming for 10 weeks and were increased by 21%-75% in skeletal muscle, heart, brain, lung and liver of rats after exhaustive swimming respectively, compared with normal control rats. (P < 0.05 and P < 0.01). But the levels of MT in blood vessel and serum were not changed in two groups of rats by swimming for 10 weeks and acute exhaustive swimming (P > 0.05). It is suggested that the different changes of MT levels under physical training and acute exhaustive exercise may be of importance in protection against oxygen free radicals. |
