【摘要】 病原微生物能够影响宿主的大脑和行为,甚至诱发精神疾患。肠道细菌可影响小鼠的神经系统发育和行为模式的发展。慢性胃肠病、慢性疲劳综合征等生理疾病中的行为改变与微生物有关;肝性脑病、多发性硬化等中枢神经系统生理疾病也可能由微生态改变引起;抑郁症、孤独症等精神疾病与肠道细菌状态和比例有关;卫生假说支持上述观点。建立良好的共生微生物平衡有利于人类身心健康。可以预期,共生微生物与身心健康的关系将是今后心理学研究的关注热点。更多还原

【Abstract】 As we know that some pathogenic microorganisms not only influence host brain and behaviors,but also cause psychiatric disorders.Recent researches indicate that beneficial symbiotic microorganisms,which also known as probiotics,may improve host health both physically and mentally.Gut microorganisms are involved in the development of the neural system and behavioral pattern of mice.They are also related to chronic gastrointestinal disorders and chronic fatigue syndrome.Some central nervous system diseases,such as hepatic encephalopathy and multiple sclerosis may be induced by the disturbance of gut micro-ecosystems.Depression and autism also may be related to the status and proportion of gut microorganisms.The observations above are consistent with the hygiene hypothesis.Balanced symbiotic microorganisms could play an important role in human physical and mental health.Although the mechanisms still remain to be clarified,various hypotheses and research models will give us a better understanding of the role of gut-brain axis in host health.We believe that the relation of symbiotic microorganisms and host health will become a promising research subject in psychology.更多还原
