ABSTRACT
Objective To study the effects of selective mild cerebral hypothermia on endogenous anti-injury mechanism in brain tissue after cardiac arrest and resuscitation. Methods Fifteen healthy mongrel dogs of both sexes were anesthetized and intubated. Cardiac arrest was induced by potassium cardioplegia and cross-clamping of aorta, vena cava superior and inferior and azygos vein and maintained for 18min. The animals were randomly divided into 3 groups group A, in which no cardiac arrest was induced, served as control ( n = 4) ; in group B animals received routine cerebral resuscitation ( n = 5) ; in group C animals received selective mild cerebral hypothermia (34℃?0.5℃) and routine cerebral resuscitation ( n = 6) . After successful resuscitation, the animals were observed for 8 hours. At the end of the experiment the parietal cerebral cortex was removed for determination of MDA, GSH, LA, FFA content and activities of SOD(T-SOD, Mn-SOD, Cu-ZnSOD) and GSH-Px. Results FFA and LA content of brain tissue in group B was significantly higher than those in group A (P
