Urinary glycine conjugates were analyzed on 242 healthy male workers and 95 healthy female workers who are not exposed to any organic solvent. The results obtained are as follows 1.No differences in the value of urinary glycine conjugates were seen between male and also, among the age groups. 2. The mean value of urinary glycine conjugates of 337 male and female workers collected at 8 to 9 a.m. were 314μg/ml and 5% rejection limits of that were 121 and 814μg/ml 3. A periodicity in the variation of urinary glycine conjugates was found during a day, being not influenced with the work shift or have or a meal.…
