Background. Previously, we found a wide range of uric acid metabolism parameters and functional relationships of uricemia and uricosuria with the parameters of immunity in healthy female rats analyzed. It was found by canonical correlation analysis that both parameters of uric acid metabolism determine the immunity status of rats by 71%. The purpose of this study is to determine the features of immune status in rats with quantitatively and qualitatively different uric acid metabolism. Material and Methods. Experiment was performed on 60 healthy female Wistar rats 220-300 g. Among them 10 animals remained intact, using tap water from drinking ad libitum. The rats of others groups for 6 days administered through the tube various fluids. The s...
