title: [Primarily study and significance of ET-1 during ischemia with RT-PCR].
abstract: OBJECTIVE
  To explore the relationship between expression of endothelin in heart and ischemia.
  
  
  METHODS
  Using the RT-PCR method, we enquiry changes of ET-1 RNA after 60min ischemia in hearts of rats.
  
  
  RESULTS
  Although the two group appear positive, they are different significantly, which indicate that ischemia may lead to the increase of ET-1 mRNA.
  
  
  CONCLUSIONS
  The experiment, therefore, pave a way for immunochemical study.
