Effects of Bushen Huoxue Recipe combined with neural stem cell transplantation in rats with tinnitus
摘要
Abstract
BACKGROUND:Neural stem cel s have multi-directional differentiation potential, self-sustaining and self-renewal capacity as wel as have strong migration ability. Bushen Huoxue Recipe can reduce neuronal damage and promote nerve cel regeneration, to achieve neural function reconstruction. Underlying mechanisms of Bushen Huoxue Recipe combined with neural stem cel transplantation in rats with tinnitus induced by sodium salicylate are yet unclear. OBJECTIVE:To investigate the effects of Bushen Huoxue Recipe combined with neural stem cel transplantation in rats with tinnitus induced by sodium salicylate. METHODS:Sixty Sprague-Dawley rats were randomized into five groups (n=12):normal control group, tinnitus model group, Bushen Huoxue Recipe group, stem cel group and combined treatment group (Bushen Huoxue Recipe combined with neural stem cel transplantation). Animal models of tinnitus induced by sodium salicylate were made in al the groups except for the normal control group. Fifteen days after modeling, rats were given intragastric administration of Bushen Huoxue Recipe water decoction (3 mL, 2.592 g/mL) for consecutive 7 days in the Bushen Huoxue Recipe group, intravenous injection of neural stem cel s (1 mL, 1.0×109/L) in the stem cel group, or their combined treatment in the combined treatment group. RESULTS AND CONCLUSION:Bushen Huoxue Recipe, neural stem cel transplantation and their combination al could effectively promote the recovery of drinking water inhibitory rate that was ranked as fol ows:combined treatment group<Bushen Huoxue Recipe group<stem cel group. Additional y, the above-mentioned methods could effectively reduce pathological damage of primary auditory cortex in the rat brain. Western blot results showed higher 5-serotonin levels in the Bushen Huoxue Recipe group and combined treatment group than in the stem cel group, which were identical to ELISA findings. Our experimental findings indicate that Bushen Huoxue Recipe combined with neural stem cel transplantation exhibit certain effects on tinnitus induced by sodium salicylate in rats, and the mechanism of action is associated with neuronal repair and expression of 5-serotonin at mRNA and protein levels.关键词
