At the end of the last century after the discovery of signaling functions of nitric oxide (NO, II), a new class of biologically active substances was admitted. It includes so-called gas transmitters acting as intercellular and intracellular regulators of different physiological functions. Currently, this class includes such gases as NO, carbon monoxide (CO) and hydrogen sulfide (H2S). It was found that these gases regulate not only functions of the. gastrointestinal tract and the cardiovascular system, where it has been determined initially, but also affect the function of the central and peripheral nervous.systems. Apparently, they constitute a single complex of gas transmitters, which easily penetrates through the membrane and regulates numerous enzymatic and non enzymatic cells reactions. This review presents the mechanisms of gas transmitters' influence on the electrical and contractile properties of smooth muscle cells (SMC) as a possible new ways to interact with the "classical" intracellular signaling cascades (Ca2+, cyclic nucleotides) and effectors systems. On account of their interactions the role of cyclic nucleotides and calcium ions in the implementation of the signal gas molecules functions is analyzed. We summarize the literature data and the results of our own research on the role of SMC membrane ion-transporting systems in myogenic effects of NO, CO and H2S and describe possible reasons of gas transmitters multidirectional influence on the excitation-contraction coupling in SMC.
