title: [Effect of fast-acting spray for heat stroke in enhancing heat tolerance of rats].
abstract: OBJECTIVE
  To observe the effect of fast-acting spray for heat stroke, a preparation of traditional Chinese drugs, in enhancing the heat tolerance in rats.
  
  
  METHODS
  Thirty SD rats were randomized into 3 groups(with 10 in each group), and group A was treated with the fast-acting spray for heat stroke, group B with chlorpromazine, and group C with cool boiled water, before they were exposed to heat at 41 degrees Celsius in a heat chamber with relative humidity of 70% till death. The rats' rectal temperature was measured before and 1 h after the heat exposure, and the time when death occurred in the rats was recorded.
  
  
  RESULTS
  In comparison with group C, the rats in groups A and B had lower rectal temperature and prolonged survival time with decrease mortality.
  
  
  CONCLUSIONS
  The fast-acting spray for heat stroke we prepared may enhance the heat tolerance of rats.
