The Oxidative Stress State of Mice After Air Simulated Diving / 环境与健康杂志

ABSTRACT

Objective To study the oxidative stress state of mice before and after air simulated diving. Methods Forty-eight mice were divided into 6 groups randomly. Every group was exposed to corresponding pressure for 60 minutes, twice a day for consecutive 3 days. Blood was obtained at the corresponding time to observe the changes of maleic dialdehyde, glutathione, glutathione-s-transferase, glutathione peroxidase, superoxide dismutase and catalase. Results Compared with the control, the activity of glutathione-s-transferase, glutathione peroxidase, superoxide dismutase, catalase and the level of glutathione were markedly inhibited and maleic dialdehyde increased in HO group and HA1 group (P
