本病原因一般人相信碘質缺乏說,我反對這個學說。先把我對它發生懷疑的經過談一下,熱河地方本病蔓延甚廣,把本病流行地的井水運至瀋陽逐日給白鼠海猽飲用,半年後則發生甲狀腺腫,最初呈組織學的實質性甲狀腺腫,一年後呈膠樣甲狀腺腫,甲狀腺腫所見於動物與人相同;然而把具有這樣作用的水煮沸冷却除去沉澱物,用上淸液給動物飲用則不發生甲狀腺腫。由於這個實驗的結果,誰也不會說水經過煮沸後碘質會增加;因此我們始懷疑到水中或可含有某種陽性因子,這是我研究本病原因的開端。看一下過去的學說,碘質缺乏說是在1851年chatin開始倡導的,當時因碘的定量法極不 The cause of the disease Most people believe that lack of iodine that I oppose this doctrine. First, I have a doubt about it After the talk, the spread of the disease in Rehe area is widespread, the well of the disease well water to Shenyang daily drink to the sea urchin, six months after the occurrence of goiter, was initially histological Substantial goiter, a year after the gel-like goiter, goiter was found in animals and humans the same; however, the role of water boil and cool to remove sediment, the upper body fluid to drink animal does not occur goiter. As a result of this experiment, no one would say that iodine will increase after the water has been boiled. Therefore, we initially suspected that water might contain some positive factor, which is the beginning of my study on the cause of this disease. A look at the past doctrine, lack of iodine is said in 1851 chatin began to advocate, because of the quantitative method of iodine is extremely
