镁与尿路结石第二次世界大战后,日本人生活欧美化使尿路结石患者增加,但从全日本看,存在明显地区差异。为寻找生活外原因,郡氏调查了全日本85个都市,方法为夏秋二次测定自来水中的Ca、Mg、P、F、Na、Fe、K、SO_4、Cl等元素,并对水源地的地质也进行调查。与1979年收集的各都道府县尿路结石发生率相比较。结果表明,尿路结石的发生率与自来水中Mg/Ca单个元素浓度无关,但与Mg/Ca比值呈负相关。即尿路结石症多的东海、近畿、中国(日本本岛西部地区)、北九州地区Mg、Ca比值下降,而尿路结石症少的北海道、东北、关东、中
Magnesium and urinary tract stones After the Second World War, the Japanese living in Europe and the United States increased urinary tract stones, but from all Japan, there are obvious regional differences. In an effort to find out-of-the-box causes, Junji surveyed 85 cities in Japan by measuring secondary elements such as Ca, Mg, P, F, Na, Fe, K, SO4 and Cl in tap water in summer and autumn. Also investigate. Compared with the incidence of urolithiasis collected in all prefectures in 1979. The results showed that the incidence of urolithiasis was not related to the single element concentration of Mg / Ca in tap water, but negatively correlated with Mg / Ca ratio. Namely, the ratio of Mg and Ca decreased in the East China Sea, Kinki, China (western part of Japan’s island) and Kitakyushu in many cases of urolithiasis, while Hokkaido, northeast, Kanto,
