It is well known that chronic ethyl alcohol (EtOH) consumption is capable to injure brain cells and to cause essential abnormalities in behavioral characteristics of animals addicted to alcohol. In this work we for the first time have shown that administration of aqueous solutions of hydrated C60 fullerenes (C60HyFn) with C60 concentration of 30nM as a drinking water during chronic alcoholization of rats (a) protects the tissues of central nervous system (CNS) from damage caused by oxidative stress with high efficacy, (b) prevents the pathological loss of both astrocytes (the main cells of CNS) and astrocytic marker, glial fibrillary acidic proteins (GFAP) and, as consequence, (c) due to their adaptogenic effects, C60HyFn significantly improves behavioral response and eliminates emotional deficits induced by chronic alcohol uptake. The wide range of beneficial biological effects, zero-toxicity, and efficacy even in super-small doses provide a rationale for the possible application of C60HyFn for the treatment of alcohol-induced encephalopathy as well as alcoholism prophylaxis.
众所周知,长期饮用乙醇(EtOH)会损伤脑细胞,并导致酒精成瘾动物的行为特征出现本质异常。在本研究中,我们首次表明,在大鼠长期酒精化过程中,给予浓度为30nM的富勒烯C60水合物(C60HyFn)水溶液作为饮用水,(a)能高效保护中枢神经系统(CNS)组织免受氧化应激损伤,(b)可防止星形胶质细胞(CNS的主要细胞)和星形胶质细胞标志物胶质纤维酸性蛋白(GFAP)的病理性丢失,因此,(c)由于其适应原性作用,C60HyFn能显著改善行为反应,并消除慢性酒精摄入引起的情绪缺陷。C60HyFn具有广泛的有益生物学效应、零毒性以及即使在超小剂量下也具有疗效,这为其可能用于治疗酒精性脑病以及预防酒精中毒提供了理论依据。
