柳澤氏血清Ca及同イオン定量法の検討

抄録

Recently, I have studied on calcium determination by Yanagizawas' method. It makes use of property that Sunchromin Fast Blue M. B produces a special colour (violet) in existence of calcium in the alkaline solution.
(1) Total calcium concentration: It must be taked more examinations to compare with other methods (to determine the total calcium concentration in serum), but I have believed that it is fairly reliable method for clinical determination. In 30 cases of the normal adult, the average of the total calcium concentration in serum was 10.3mg/dl.
(2) diffusible calcium concentration: I could not get a satisfactory result from this method about the determination of diffusible calcium concentration. It is believed that the clinical worth is doubtful in present day.
