Abstract:
Objective To observe the changes in contents of ? 1 Microglobulin (? 1 M) in urine after exposure to acceleration of different speeds(+Gz) in order to provide scientific indications for efficient protection for pilots under high +Gz acceleration and efficient flight health service support. Methods Six healthy men were subjected to the following experiments: ①pressurized anti G suit (KH X); ②pressure breathing for +Gz (PBG); ③pressurized anti G suit and PBG and AGSM (up to +9Gz for 10 s). Urine samples were collected before, immediately after, 30 minutes and 24 hour after the exposures for the determination of ? 1 microgolbulin (? 1 M). Results It was found that ①The G tolerances of subjects under 3 conditions were (6 25?0 52) G/10s, (8 17?0 26) G/10s, 6 5G/30s, and 9 00 G/10s, respectively. ②30 minutes after each series of exposure, the contents of ? 1 M in urine samples were increased ( P
