犬心嚢膜の電解質代謝に関する臨床生理学的研究—I．Cl36及びCl35の心嚢膜透過率に関する比較研究

Studies of the Rate of Transfer of Cl36 and Cl35 across the Intact Pericardium of Dogs.

I．緒言

　さきに正常犬の心嚢膜を透過する重水（D₂O）の透過率について検討したが^1），続いて心嚢膜を透過する電解質の中，Cl³⁶（放射性同位元素）を用いて体液の平衡状態におけるCl³⁵（正常電解質）の透過率を調べる事にした。この報告は，正常心嚢膜の平衝状態における電解質の生理学的溶液（リンゲル氏液，及び血漿）中での透過率を比較検討するものである。

　The rate of transfer of Cl³⁶ across the normal intact pericardium of dogs has been studied as a tracer in Ringer's solution and in plasma. In these comparative studies the rate of transfer of Cl³⁶ in Ringer's solution was the same as that of Cl³⁶ in plasma across the pericardium of dogs.

　The rate of transfer of Cl³⁵ across the normal intact pericardium of dogs was 153 mEq per day.
