[The central mechanisms regulating the blood circulation in hyperuricemia].
In experiments conducted on male Wistar rats for elucidation the role of central mechanisms in development alterations of heart electric stability was studied activity of 5(1)-nucleotidase and adenosine desaminase in sensomotor cortex, hypothalamus and hippocamp. Were shown that changes of heart function were in case increased adenosine content in neurons of sensomotor cortex, hypothalamus and hippocamp. Introduction to animals with hyperuricemia DOCA, with activate 5(1)-nucleotidase and adenosine desaminase, was accompanied by changes of cAMP and cGMP content in neurons. Developing alterations of heart electric stability suggest the responsibility of injury adenosine metabolism in different brain structures of animals with hyperuricemia in alterations of central regulatory mechanisms of systemic blood flow.
