Pathogenic Mechanism of Infective Brain Edema / 中国医师杂志

Objective To understand the pathogenic mechanism of ?-endorphin(?-EP) on infective brain edema(IBE).Methods Experimental IBE was induced by pertussis bacilli in rabbits.Forteen rabbits were divided randomly into two groups:Normal saline group(NS,n=7),pertussis bacilli group(PB,n=7).Water content(WC) in brain tissue and ?-EP were measured in plasma,cerebrospinal fluid(CSF),cortex and hippocampus in two groups respectively.Results WC was singnificantly higher in the PB group than those in the NS groups(P
