Superoxide dismutase (SOD) is an important superoxide anion free radical (O2) scavenger, it is the most important defense enzyme for the body to protect against oxygen damage, which plays an important role in the oxidation and antioxidant balance of the body. In the case of damage to the body under hypoxic hypoxia or myocardial ischemia, there have been many reports, but all reported a single factor reaction, kllllll00aSD, the role of multiple factors reported rarely. Both the normal body and the diseased body may be in a cold and oxygen-deficient environment, such as plateaus, high altitudes, and severe cold, this article is under the corresponding conditions of simulation, to investigate the damage of normal and myocardial ischemic body caused by low temperature and low oxygen snow transportation. This paper through the ice and snow sports of mice and determination of plasma SOD activity during recovery, obtained the dynamic curve, and observed the activity of plasma SOD temporarily decreased during the exercise period, the, while it increased significantly during the recovery period, and increased significantly during recovery. This may be due to the duration of the exercise, in order to eliminate increased oxygen free radicals, the consumption of SOD increased, and the activity of plasma SOD decreased temporarily; During the recovery period, on the one hand, SOD is still compensatory increasing, On the other hand, the generation of oxygen free radicals is reduced, and the SOD consumption is lowered, so that the activity of plasma SOD is increased.
