食品添加物の心臓収縮性への影響 Effects of Food Additives on the Contractility of the Heart 西丸, 和義 ニシマル, ヤスヨシ Nishimaru, Yasuyoshi 食品添加物 心臓収縮性 application/pdf The toxicity and safety of food additives are tested in our country by such procedure as determining the lethal dose to animals or determining the acuteness，subacuteness，or chronicity of their effects. That is， the methods employed are for the most part pathologic and not physiologic in nature. At present， however, many authorized additives commercially available on the market are found to be toxic, presumably because of the weakness of the tests required for granting authorization. Censidering it important therefore to develop physiologic methods of testing, the authors seek to clarify the effects of these additives on the circulatory and nervous systems and the liver of the bullfrog and to proceed further to experimentation with mammals. In our first report，their effects on the contractility of the heart of the bullfrog will be described. 広島女学院大学 1970-12-20 jpn departmental bulletin paper VoR https://hju.repo.nii.ac.jp/records/1013 0374-8057 広島女学院大学論集(自然科学・家政学篇) 20 1 11 https://hju.repo.nii.ac.jp/record/1013/files/ronsyu20nishimaru.pdf application/pdf 520.2 kB 2023-03-03
