[Dynamics of uric acid concentration in the liver of cockerels subjected to model stress situations induced by fasting].
A model stress situation was created by nutrition deprivation. The experiment was performed with 130 cockerels of the initial breed White Leghorn. The experimental cockerels of the age of 18 to 24 days fasted for 24, 48 and 72 hours. Uric acid was determined in the supernatant of liver homogenate by means of a colorimetrically reductometric method with phospho-wolframic agent. A significant increase in the uric acid concentration in the liver of cockerels was found out during the model stress: the concentration of uric acid increased progressively from the initial 70.25 +/- 8.94 mg per 100 g to 93.15 +/- 9.66 mg per 100 g after 24-hour fasting, to 90.23 +/- 7.84 mg per 100 g after 48-hour fasting and even to 137.04 +/- 15.59 mg per 100 g after three-day fasting of 72 hours. After re-alimentation, the concentrations of uric acid were reduced to physiological values already within 24 hours.
