“在太空飞行中,宇航员长期在复合压力环境中生活,身体会经历各种变化,例如因失重造成的骨骼肌萎缩、脑部发胀、昼夜节律失调以及因暴露于太空辐射造成的免疫功能低下。我作为一名医生同时也是一名宇航员,在国际宇宙空间站工作的将近5个半月时间里,以上种种我都经历了。” 10月25日,日本国立研究开发法人宇宙航空研究开发机构古川聪组长在“第9届养乐多代田研讨会”上分享道。10月25日-26日,包括古川聪组长

10月25日-26日,包括古川聪组长在内的数百名来自中国、美国、英国、日本、澳大利亚、新加坡、马来西亚、比利时、泰国等国的专业学者齐聚东京的株式会社养乐多本社,先后参加了“第9届养乐多代田研讨会”和“第27届肠内菌群国际研讨会”,聚焦肠道菌群与平衡失调,分享关于多元化益生菌的最新研究进展与成果。

日本宇宙航空研究开发机构携手养乐多开展共同研究

据古川聪组长介绍,从2014年开始,株式会社养乐多本社与日本国立研究开发法人宇宙航空研究开发机构一起开展共同研究,试图证明宇宙飞行改变了人类的肠道菌群及免疫系统,以及持续摄入益生菌可以改善一些机体变化的两个假设。

10月25日-26日,包括古川聪组长在内的数百名来自各国的专业学者齐聚东京,先后参加了“第9届养乐多代田研讨会”和“第27届肠内菌群国际研讨会”,聚焦肠道菌群与平衡失调,分享关于多元化益生菌的最新研究进展与成果。

“益生菌是活的微生物,并且通过改善肠内环境给机体提供有益的影响。在众多的益生菌中,我们着重选取了由养乐多自主分离、筛选的干酪乳杆菌代田株(Lactobacillus casei strain Shirota,以下简称LcS)。”古川表示,“LcS已有80多年的安全饮用历史,它可以活着到达肠道,保持并且提高机体抵御力,而且可以改善肠内菌群平衡。”

如今,全球第一例在宇宙中持续摄入LcS的实验已于2017年正式启动并且仍在进行中,目前实验对不同环境下LcS的活菌数、菌的发酵特性、遗传信息、免疫调节作用进行了分析,发现在国际宇宙空间站中的LcS保存品和陆地上的对照品之间不存在差别,确认了在宇宙中益生菌LcS也能维持其原本的功能。“希望今后的实验结果不仅可以帮助在外太空环境下人员的身体健康,也可以帮助那些在地球中处于高压状态的,比如身处于自然灾害、高海拔环境及深海环境的人类健康管理。”古川聪说。

临床实验揭示肠内菌群对身心健康的影响

在肠内菌群研究中,此前很少有实验去探讨抑郁症患者肠内菌群情况。在“第27届肠内菌群国际研讨会”上,日本国立精神·神经医疗研究中心神经研究所疾病研究部功刀浩部长指出,针对抑郁症患者肠内菌群进行的研究揭示:与乳酸杆菌和双歧杆菌有关的益生菌可以减缓在动物实验中与抑郁相关的表现。实验同时发现,与健康人群相比,抑郁症患者的双歧杆菌及乳酸杆菌的数量有显著性的减少。在抑郁症患者中,每周摄入发酵乳制品少于一次的患者其双歧杆菌计数较其他患者呈现显著性地降低。“一个海外随机对照实验结果证实了益生菌对抑郁症患者有益。”功刀浩部长说,“使用益生菌或益生元也许可以治疗由压力引起的心理疾病,并为未来的临床实验提供支持。”

此外,在题为《生态失调,菌群-脑肠中心轴对身心健康的影响》演讲中,美国科罗拉多大学波德分校的Christopher A. Lowry教授介绍了具有免疫调节功能的益生菌对患有创伤后应激障碍的退伍老兵的有益功能临床实验结果。应激障碍症是指人在心理、生理上不能有效应对自身由于各种突如其来的、并给人的心理或生理带来重大影响的事件,例如战争、火灾、水灾、地震、传染病流行、重大交通事故等灾难发生所导致的各种心理生理反应。Christopher A. Lowry教授表示:“研究发现,心理社会应激障碍会引起肠道失调,而分歧杆菌菌苗可以保护促炎症的肠道菌群,从而能够预防创伤后应激障碍综合症状的发展。”

养乐多:益生菌领域的先锋者

在欧洲,人们认为酸奶可以解决乳糖不耐受症,而对益生菌则持谨慎的态度。作为益生菌领域的先锋者,养乐多公司多年来不断对其自有菌株“干酪乳杆菌代田株”开展研究,实验涉及便秘领域、细菌和病毒感染、肝脏疾病和胰岛素耐受领域等。在“第9届养乐多代田研讨会”上,欧洲养乐多公司主管学术业务的董事布鲁诺·布特先生分享了干酪乳杆菌代田株(LcS)在欧洲的最新研究进展。

他表示,多项实验和研究发现,摄入LcS可以显著降低粪便的硬度,减轻便秘患者的便秘程度;在细菌层面,可以显著降低脊髓受损患者的抗生素相关性腹泻;在肝脏疾病方面,摄入LcS对代偿期肝硬化的患者是安全的;在胰岛素耐受性领域,摄入LcS的益生菌组可以抑制二型糖尿病的发生率。

值得一提的是,来自中国南昌大学、山西医科大学、青岛大学、中国农业大学、天津科技大学、上海第九人民医院的多位教授专家,以及多所高校的博士生和研究生也受养乐多邀请,远赴日本参与此次研讨会。通过与各国专家进行学术交流,探讨益生菌行业研究动态,与会中国学者深受鼓舞:“参与这类全球化、专业性强的国际研讨会,能够让我们了解研究的最新成果,为我们未来的研究方向带来了全新启迪。”
