METHODS： The total of 21 male Wistar rats aged 37 d old were divided into three groups, namely ethanol, ethanol-curcumin, and control groups. The ethanol group received 1.5 g/kg ethanol injected intraperitoneally and water given per oral; the ethanol-curcumin group received 1.5 g/kg ethanol injected intraperitoneally and curcumin extract given per oral; the control group received saline injection and oral water. The treatment was carried out daily for one month, after which the motor coordination performance of the rats was examined using revolving drum apparatus at test days 1, 8, and 15. The rats were finally sacrificed and the cerebellum of the rats was further processed for stereological analysis. The estimate of the total number of Purkinje cells was calculated using physical fractionator method. RESULTS： The ethanol-curcumin group performed better than both ethanol and control groups in the motor coordination ability at day 8 of testing （P〈 0.01）. No Purkinje cell loss was observed as a result of one month intraperitoneal injection of ethanol. CONCLUSION： Curcumin may exert beneficial effects on the motor coordination of adolescent rats exposed to ethanol via undetermined hormetic mechanisms.展开更多

The injury may cause vast damage of extracellular matrix leading to the condition wherein cell lost their environment to live. In this situation, new strategies by the introduction of scaffold to function as synthetic extracellular matrix are needed. In the field of tissue engineering, a large variety of carriers and matrices have been utilized as a scaffold to direct axonal growth. In this study, a new strategy by the combined application of gelatin hydrogel film and Platelet Rich Plasma (PRP) to induce functional recovery of sciatic nerve crushed injury was investigated in Wistar rat model. Assessment of motorist and sensory functions were done to evaluate the recovery processes. It was found that the application of gelatin hydrogel film with controlled release manner combined with PRP results faster axonal regeneration. Further research by different injury model and other investigation factors are needed to confirm the effectiveness of the strategy.展开更多
