摘　　要：研究了虎斑颈槽蛇骨骼肌、肝脏、心肌组织中琥珀酸脱氢酶（SDH）、乳酸脱氢酶（LDH）活性对温度的依赖关系。结果表明：虎斑颈槽蛇骨骼肌、肝脏、心肌SDH在5-15℃范围内表现出较低活性，在25℃左右表现出较高活性，该温度可能为SDH的最适温度；除心肌KLDH活性在35℃以上开始下降，其余两种组织的LDH活性随温度的上升而升高。SDH、LDH活性呈现组织问的特异性，3种组织中，SDH活性心肌中最高，LDH活性骨骼肌中最高。The temperature dependences of SDH and LDH activities of skeletal muscle, liver and cardiac muscle in Rhabdophis tigrinus lateralis were studied. The results showed that SDH activities of skeletal muscle, liver and cardiac muscle had the low activeness in the scope of 5 - 15℃, and the high activeness at 25℃. The optimum temperature for SDH might be 25℃ in three kinds of tissues. Except that, LDH activity of cardiac muscle in 35℃ above started to drop, and LDH activeness in other two kinds of tissues elevated along with the temperature rise. At the same time, SDH and LDH activities presented the specificity between tissues. In three kinds of tissues, SDH activity of cardiac muscle was higher than that of other two kinds of tissues, and LDH activity of skeletal muscle was higher than that of other liver and cardiac muscle.
