title: [Effects of thermal injury on production of nitric oxide in rat heart].
abstract: To elucidate the relationship between thermal injury and production of nitric oxide (NO), we measured the levels of heart No2-/NO3- (the stable and products of NO) and GMP in rats with full thickness burn of 30% TBSA. A higher level of heart tissue NO2-/NO3- was observed from 3 to 24 hours after burn injury. Parallel to the changes of NO2-/NO3-, there were increases of tissue cGMP level and heart tissue water content in burned rats. L-NMMA, a specific inhibitor of NO synthetase (NOS), can block the rise of heart NO2-/NO3- and the enhancement of heart water content. The results indicate that the heart injury caused by burn injury may be associated with induction of NOS and formation of NO.
