Baseando-se nos efeitos estimuladores do metabolismo energético pelo pré-condicionamento isquêmico (PCI) no tecido hepático, estudou-se dois grupos de ratos cirróticos submetidos a isquemia de 20 min e reperfusão de 120 min, após o PCI ou não respectivamente, determinando assim o valor do seu uso no prolongamento da manobra de Pringle e na regeneração hepática na hepatectomia.We studied the influence of ischemic preconditioning in rat liver cirrhosis.The cirrhosis were induced in wistar rat with occlusion of biliary duct before 30 days operation and divided into group A, ischemic preconditioning and ischemic/reperfusion, and group B, only ischemic/reperfusion. In group A the preconditioning consisted of 5 min ischemic and 10 min reperfusion. The ischemic/reperfusion consisted of 20 min ischemic and 120 min reperfusion for both groups. The level of respiratory control reason (RCR) in the liver tissue 120 min after reperfusion was not difference significantly in the groups. Therefore it suggests that the preconditioning cam be viability and another object of studies must be rated in future this work.
