摘　　要：研究了密点麻蜥肝脏、骨骼肌、大脑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:密点麻蜥3种组织中SDH在5～35℃范围内随温度的升高而升高,在35℃时达到峰值后随着温度的升高而下降,35℃可能为SDH的最适温度;3种组织的LDH活性随温度的升高而升高;大脑中的SDH和LDH活性最高。这表明SDH和LDH的活性与动物组织的能量代谢相适应。The relationship between temperature and the activities of SDH and LDH were studied in skeletal muscle, liver and brain of Eremias multiocellata. The results showed that the SDH activity in all the three kinds of tissues increased as the temperature went up to 35℃, but then decreased when the temperature was further elevated. The optimum temperature for SDH activity might be 35℃. LDH activity in the three kinds of tissues increased with the temperature rising at all the tested temperatures. SDH and LDH activities in brain were higher than those in the other two kinds of tissues. It is concluded that SDH and LDH activities are adapted to the energy metabolism in tissues.
