| Abstract: | Increased excretion of uric acid and cAMP has been observed in many pathological conditions in man, but interrelation between behaviour of uric acid and cAMP is not well known. To investigate these aspects of purine metabolism the authors have studied behaviour of plasma and urinary cAMP in 8 subjects after intravenous rapid load of fructose (0.5 g/Kg b.w.) compared with the uric acid one. The results have shown that urinary excretion of cAMP after load of fructose is increased, but levels of plasma cAMP remain unchanged. These data confirm consensual relation between urinary uric acid and cAMP excretion, but the exact mechanism of this relation remains unexplained. |
