RESULTS	Upon reperfusion , however , there was a significant fall in ATP ( 23.7 + / - 1.6 micromol/g wet weight amino acids , P < 0.05 ) and in amino acids ( 1.53 + / - 0.24 micromol/g wet weight , P < 0.05 ) in the group receiving only cold blood cardioplegia but not in the hot shot group ( 2.27 + / - 0.27 micromol/g wet weight ATP and 30.5 + / - 1.6 micromol/g wet weight amino acids ) .\
