Neurology:你喝的牛奶中含有七氯么?小心患帕金森病!

2015-12-10 QQduhq 译 MedSci原创

据美国环境保护署(EPA)介绍,七氯(一种杀虫剂)在1960-1970年间被广泛用于杀灭居民家中的白蚁,农民也使用它们杀死农作物(特别是玉米)上的昆虫。 1970-988年,七氯被禁止在美国销售。现在它只局限于杀灭电力变压器上的火蚁。 但是大家并不清楚七氯对人类健康的危害。EPA引用动物研究表明,长期接触七氯会影响机体的肝脏和肾脏功能,使民众出现颤抖和抽搐。 在小鼠模型中会导致实验小鼠出现生殖和发

据美国环境保护署(EPA)介绍,环氧七氯(一种杀虫剂)在1960-1970年间被广泛用于杀灭居民家中的白蚁,农民也使用它们杀死农作物(特别是玉米)上的昆虫。 


1970-988年,环氧七氯被禁止在美国销售。现在它只局限于杀灭电力变压器上的火蚁。 

但是大家并不清楚环氧七氯对人类健康的危害。EPA引用动物研究表明,长期接触环氧七氯会影响机体的肝脏和肾脏功能,使民众出现颤抖和抽搐。 在小鼠模型中会导致实验小鼠出现生殖和发育问题。 

帕金森病是一种逐渐进展的大脑疾病,它会影响患者的运动功能、肌肉控制力和平衡感,使机体的自我控制和协调能力减退。既往研究表明,乳制品与帕金森病之间存在某种联系,但是这项研究表明牛奶与帕金森病存在某种关联。

大津志贺大学的R. D. Abbott博士和他的同事们对449名日裔美国人(他们均为Honolulu-Asia老龄化研究的参与人员)进行了随访调查。参与者平均年龄为54岁,研究人员对他们的随访时长达30多年,直到他们死亡。然后对他们的尸体进行解剖,观察他们的大脑的黑质区是否失去了大量的脑细胞。这是帕金森症的一个特征,在患者表现临床症状的几十年前便可出现。研究人员还测量了116名参与者大脑中的环氧七氯的残留量。 

20世纪80年代早期,夏威夷牛奶中的环氧七氯(用于杀灭害虫)含量非常高。

饮用牛奶的民众中90%的民众机体内会残留有环氧七氯。相比之下,在从不饮用牛奶的民众中,有63%的民众机体内会残留有环氧七氯。对于不吸烟者而言,若饮用牛奶量超过2杯/天,则他们大脑黑质的脑细胞数量较每天饮用牛奶量少于2杯的民众少40%;对于吸烟者,牛奶饮用量与大脑黑质脑细胞数量无关。这与之前表明吸烟降低民众罹患帕金森病风险的研究结果相符。

研究的局限之处在于无法证明民众饮用的牛奶中含有环氧七氯。研究只是表明存在着这样的关联,并不是绝对的因果关系。Honglei Chen博士认为,还必须考虑参与人员的饮食习惯等因素。
