Objective: To evaluate fasudil effects on EAAT2 and ROCK2 protein expressions in rat model of neonatal hypoxic-ischemic brain damage (HIBD). Methodology: 144 Seven-day-old Wistar rats were randomly divided into sham, HIBD, and fasudil groups. Fasudil group were injected intraperitoneally with that compound. Rat brains at 2, 6,12, 24, 48 and 72 h after HIBD were collected to determine histopathological damage and the expression levels of EAAT2 and ROCK2 proteins selected as the average optical density (AOD).Results were reported as average (x)standard deviation (SD), and single-factor analysis of variance (ANOVA) was performed between the multiple groups. A value of P <0.05 was considered statistically significant. Results: Histopathological damage was reduced in fasudil groups compared with the untreated HIBD group. The expression of ROCK2 in the HIBD group was significantly higher than that in SHAM and fasudil groups at the same times. EAAT2 expression was significantly decreased in HIBD group. Fasudil increased that expression. Conclusion: Fasudil reduced expression of Rock2 and increased expression of EAAT2. The increase in the expression of EAAT2 constitutes one of the pathways by which fasudil acts and that can explain its neuroprotective effects. Nevertheless further investigation should be conducted to better understand the mechanism of action of fasudil in neuroprotection it could bring in this disease.
