The changes of the ratio of NO/ET and the hepatic injury were observed in a rat hepatic I/R model pretre ated with several tool drugs. In the acute phase of hepatic I/R injury, the rati o of plasma NO/ET was reduced from 1.58 ± 0.20 to 0.29 ± 0.05 ( P < 0.01) a nd the hepatic damage deteriorated. NO donor L Arg and ET receptor antagonist T AK 044 cou ld alleviate the hepatic I/R injury to some degree, whereas NO synthase inhibito r L NAME aggravated the damage. It was concluded that the hepatic I/R injury mi ght be related with the disturbance of the NO/ET balance. Regulation of this bal ance might have an effect on the I/R injury.展开更多
