Study on the cerebral protection of fasudil for hypoxic-ischemic cerebral damage of neonatal rats / 实用医学杂志

ABSTRACT

Objective To investigate the effect of the cerebral protection and possible mechanism of fasudil for hypoxic-ischemic cerebral damage (HIBD) in neonatal rats. Methods The HBID model was established, then the mice were randomly divided into different groups. The expressions ofα-SMA and ROCK-2 were detected in the newborn rats with ischemia. Results Compared with the model group, expressions of α-SMA, ROCK-2 decreased in each treatment group with significant differences (P < 0.05 or P < 0.01). Following with the increases of administration dose and the administration time, expressions of α-SMA, ROCK-2 decreased gradually with significant differences (P<0.05 or P<0.01). Conclusion Fasudil can reduce the expressions of α-SMA, ROCK-2 in the newborn mice with hypoxic-ischemic brain damage to attenuate the brain tissue hypoxic-ischemic injury. The protective effect on brain is significant by giving high-dose fasudil in the early neonatal rat HIBD (0 h).
