Abstract:
Objective To observe the effects of psychological pretreatment on the stress reaction of simulated fast buoyancy ascent escape in rats. Methods Forty healthy rats were randomly divided into 4 groups:the control group, the psychological stress group, the fast compression and decompression group, and the psychological stress pretreatment plus fast compression and decompression group. By developing the fast buoyancy ascent escape rat model with fast compression and decompression in a closed cabin, the effects of psychological pretreatment on the stress reaction were observed in the course of ascent. Results Hear t rate of the animals in the psychological pretreatment stress group was significantly higher than that in the control group (P＜0. 05), and the expression of serum TNF-α was significantly lower than that in the control group (P ＜ 0.05 ). Conclusions Psychological factor seemed to have positive effects on the stress reaction of the simulated fast buoyancy ascent escape in rats.
