Abstract:
Objective To investigate the influnce of dexamethasone pretreatment on the expression of ICAM 1 and neutrophil infiltration in brain tissue of hypoxic ischemic neonatal rats Methods Forty eight neonatal rats were made to model with hypoxic ischemic encephalopathy(HIE) The control group and the dexamethasone group were respectively injected intraperitoneally with normal saline 10 ml/kg, dexamethasone 0 1 mg/kg before hypoxia ischemia;all animals were killed 24 hours after hypoxia ischemia Immunocytochemistry was used to determine the absorbency of ICAM 1 The damage grade of neurocytes and leukocyte infiltration were recorded for the histopathological study Results Compared to the control group,the mean absorbency(A) of ICAM 1, the damage grade of neurocytes and neutrophil infiltration of the dexamethasone group were all obviously decreased( P
