Abstract

It was investigated the intercommunication of the functional state of cyclic nucleotides (CN) system and morphofunctional states of lung and heart tissues and influence on these state of lipid peroxidation processes and adenylate cyclase system activity under development in organism of the hypoxic states of different genesis. Obtained dates testify that with the changes of cAMP and cGMP concentrations, and also with their ratio the level of hyperhydration of air-blood and blood-tissue barriers under the used influence on the organism are closely correlated. Intercommunication of the cyclic nucleotides sys­tem functioning and tissues oxygen consumption at the used influences carries sufficiently difficult and ambiguous character. It was shown that exactly at blood loss in lung and heart tissues there were the parallel diminishing of concentrations both cAMP and cGMP. It is accepted to correlate with a favorable histological dynamics. Exactly under these condi­tions the correlation of CN concentrations is possible to consider balanced and sent to limitation of displays of unfavorable influence of blood loss on investigated tissues ultrastructure. So, there is a tissue specific and depending from the type of influence on the organism character of inter­communication of the functional state of cyclic nucleotides system and morphofunctional states of lung and heart tissues.

Keywords: cyclic nuсleotides, morphofunctional state, hy-poxic hypoxia, acute blood loss, immobilization stress, LP,adenylate cyclase
