Abstract

In the 107 normal Korean subjects, 71 males and 36 females, he determination of the maximum urea clearance has been performed and the following results were obtained. 1. The maximum urea clearance corrected to the Korean standard body surface area, 1.57 square meters, are 70.5 +/- 5.53(40.0-101.8) ml./min. in average, 70.5 +/- 16.1(40.0-101.8) ml./min. in the males and 70.4 +/- 13.93 (42.9-93.5) ml./min. in the females. When corrected to the American standard body surfacearea, 1.73 sq.m., they are77.8 +/- 16.9 (43.6-112.2) ml./min., 77.7 +/- 17.7 (43.6-112.2) ml./min. and 78.1 +/- 15.0(47.3-103.1) ml./min., respectively. 2. The results of the standard urea clearance determination performed in 44 normal Korean subjects, 31 males and 13 females, are 39.2 +/- 6.62(30.0-61.1)ml./min. in average, 39.7 +/- 5.74(30.3-53.2) ml./min. in the males and 38.0 +/-8.64(30.0-61.1) ml./min. in the females when corrected to the Korean standard body surface area, 1.57 sq.m., and 41.0 +/- 6.84(31.6-63.6) ml./min.41.6 +/- 5.83(31.8-55.2) ml./min. and 39.8 +/- 9.03 (31.6-63.6) ml./min. when corrected to the American, respectively. 3. These determinations are similar to other investigators. A considerable daily fluctuation in the standard urea clearance is observed, and the maximum urea clearance, which is more stable, should be preferably performed for the determination of urea clearance.
