Abstract
The author has reported in the last paper the improved micromethod for the quantitative analysis of dextran and caramel, which was proved to be superior to the Bloom & Wilcox's method. In the present paper, the author reports the results of the examination of the rate of recoveries of dextran and caramel in serum and urine, of the time of retention in blood and of the rate of discharge in urine, by means of the improved method.
The recoveries of dextran (alkali-digest method) and caramel (deproteinizing by 5% of trichloracetic acid) in serum and urine were 96-99% and the method was proved to be useful for the biochemical application. Examination of the excretion rate of 100ml of dextran and caramel in the normal adult human blood, revealed that the former remained over 72 hours, as Bloom and Wilcox reported, and the latter excreted within 6 hours.
