Nitrogen partition in urine of Burmese subjects

ABSTRACT

The present study aims at establishing a standard of reference on the different constitutents of urinary nitrogen for Burmese subjects. Twenty-foru-hour urine samples of 100 Burmese subjects were collected and analysed for volume, specific gravity, pH, titratable acidity, total nitrogen, urea nitrogen, uric acid, ammonia nitrogen, aminoacid nitrogen and creatinine. Creatinine coefficient and the undertermined nitrogen were also calculated. The age, body weight and height of the subjects were recorded and their body-surface area measured. The total nitrogen, urea nitrogen and the urea nitrogen as percentage of total nitrogen was much lower than those of Europeans and Americans but paralleled those of Indians. This may be due to the greater protein intake by the Europeans and Americans than by the Indians and the Burmese.
