温度对荒漠沙蜥肝脏组织中SOD活性的影响

The effects of temperature on SOD activity in the liver of desert lizard Phrynocephalus Pzewalskii

利用NBT光化学还原法测定在4℃,25℃及35℃条件下驯化15天的荒漠沙蜥肝脏组织中SOD的活性.结果表明:4℃驯化的蜥蜴的SOD活性最低,为3 661.69±369.828 u／(h·gFW);25℃驯化的蜥蜴的SOD活性有所增高,为4263.17±269.124 u／(h·gFW);35℃驯化时,SOD活性最高,为4683.72±172.186 u／(h·gFW).各组间SOD活性差异显著(P<0.05).荒漠沙蜥肝脏组织中SOD活性与温度具有关联性,而这与机体在不同温度下的生理机能是密切相关的.

In this paper the effects of temperature on SOD activity in the liver of a desert lizard were studied. The lizards were acclimated at 4℃, 25℃ and 35℃ respectively for 15 days. And the SOD activities were measured by NBT-illumination method. The results showed that acclimating the desert lizard at 4℃, the SOD activity was 3661.69±369.828u/(h·gFW), was the lowest; at 25℃, the SOD activity was 4263.17±269.12u/(h·gFW); when the acclimated temperature was 35℃, the SOD activity was 4638.72±172.186u/(h·gFW), which was the highest(F<0.05) was significantly different from the values of the other temperatures). Therefore, the SOD activity is related with the temperature and this relationship involves the physical states of the desert lizard at the different temperatures.
