Four chickens were used in nine successive experiments using a single injection radioisotope dilution technique to study the kinetics of endogenous uric acid and urea metabolism. 2. Starvation lowered uric acid and urea entry rates, but elevated the extent of degradation of these compounds. 3. Urea turnover time and the extent of urea pool degradation were higher, and urea excretion rate was lower than that of uric acid. 4. In colostomised chickens, the extent of uric acid and urea degradation were lower than in non-colostomised birds. 5. The average uric acid and urea entry rates in chickens fed on a diet containing 200 g protein/kg were 7.32 and 2.6 mumol/h g liver, respectively. 6. It is concluded that the contribution of uric acid and urea to the nitrogen economy of the birds is negligible.

在九个连续实验中，使用四只鸡采用单次注射放射性同位素稀释技术来研究内源性尿酸和尿素代谢的动力学。2. 饥饿降低了尿酸和尿素的进入速率，但提高了这些化合物的降解程度。3. 尿素周转时间和尿素池降解程度更高，且尿素排泄率低于尿酸。4. 在做了结肠造口术的鸡中，尿酸和尿素的降解程度低于未做结肠造口术的鸡。5. 以每千克含200克蛋白质的日粮喂养的鸡，其尿酸和尿素的平均进入速率分别为每克肝脏每小时7.32微摩尔和2.6微摩尔。6. 得出的结论是，尿酸和尿素对鸟类氮代谢的贡献可忽略不计。
