title: [Changes of serum biochemical parameters during hypothermia and hypoxia in rats].
abstract: OBJECTIVE
  To study the effects of hypothermia and hypoxia on serum biochemical parameters. Method Acute hypobaric hypoxia experiment in cold environment was carried out in 48 healthy Wistar rats to observe changes of hepatic, cardiac and renal functions.
  
  
  RESULTS
  Hepatic, cardiac and renal functions changed non-prominently after acute hypoxia exposure under cold condition. Under hypoxic exposure of the same degree, serum lactic dehydrogenase(LDH), alanine transaminase(ALT), blood urea nitrogen (BUN) and creatinine (Cr) increased more significantly at 10 degrees C than those at 20 degrees C (P < 0.01) while creatine kinase (CK) decreased significantly at 10 degrees C than that at 20 degrees C.
  
  
  CONCLUSIONS
  After acute hypoxia in cold environment, the changes in cardiac function did not simply equal to the changes by cold environment plus changes by acute hypoxia.
