Abstract:
Objective To explore the possible effect of Nogo-A receptor antagonist NEP1-40 on neurite outgrowth in neonatal rats with hypoxic-ischemic brain damage(HIBD).Methods Sixty-four healthy Wistar rats were randomly divided into 8 groups at 2 different time points(6 h,24 h):control group,HIBD group,NEP1-40 group and ganglioside group(GM-1 group).Rats of control group and HIBD group were injected with saline(0.25 mL/kg)by intraperitoneal injection,while rats of NEP1-40 group and GM-1 group were administrated with 10 mg/(kg?d) NEP1-40 and 20 mg/(kg?d) GM-1 on request in each group,respectively.Immunohistochemical staining was adopted to detect the Nogo-A-positive cells,and ultrastructural changes of neuron and axon were observed by transmission electron microscopy.SPSS 13.0 statistical software was used to run One-Way ANOVA tests on the data presented.Results The Nogo-A-positive cells at 2 time points in rats of HIBD group were significantly higher than those of control group(t=7.63,15.13 Pa0.05),while the Nogo-A-positive cells in GM-1 group at 24 h was lower than that of HIBD group(t=4.25 P
