Nerve growth factor attenuates cochlear injury induced by brain ischemia and reperfusion in rats / 中国病理生理杂志

ABSTRACT

AIM: To investigate the effect of nerve growth factor (NGF) on auditory and cochlear damage induced by brain ischemia and reperfusion. METHODS: The rats with brain ischemia and reperfusion were divided into two groups at random. In the experimental group, the rats were injected intramuscularly with NGF . In control group, the animals were injected with normal saline instead of NGF. Then the hearing loss and cochlear structural changes of rats in both groups were compared. RESULTS: It was found that the hearing loss of rats in NGF group were less significantly than that of control group ( P
