Abstract:
Objective: To investigate the effects of simulated altitude acute hypoxia on appetite and orexin mRNA expression in rats. Methods: Rats were exposed to hypobaric chambersimulating different high altitude (3000m,4000m,5000m,6000m) for different times (8h/d;1d,3d and 7d respectively), and the changes of appetite, weight gain, and the orexin mRNA expression in hypothalamus of rats were examined. Results: With the increasement of hypoxia time and simulated altitude, the total food intake of rats and the orexin A and B mRNA expression in hypothalamus decreased gradually as compared with control. After 7 days of hypoxia, the weight gain of rats was significantly different(P
