title: [A problem on the uric acid value of rats for clinical evaluation].
abstract: Routine monitoring on levels of serum uric acid in the rats has been widely employed as an important factor in the nucleic acid metabolism, despite of the presence of the uricase in them. In this paper, it is confirmed that the levels of allantoin in serum and urine of the normal rats were higher than those of uric acid. Therefore, the concentration of allantoin in serum and urine of the rats with abnormal nucleic acid metabolism caused by adenine administration were measured. The results indicated that the value of serum allantoin was more sensitive to abnormal nucleic acid metabolism.
