[Catecholamine-induced changes of the kinetic properties of adrenergic receptors of the myocardium].

The pattern of changes in kinetic properties of beta-adrenoreceptor (Cd, c+ and c-) relative to anapriline adrenoblocker under conditions of muscle perfusion by catecholamines has been estimated on papillary cardiac muscles of the rat as based on the isometric voltage. A priority increase of the receptors' affinity to the blocker is determined, that may be a result of changes in microviscosity of the lipid sarcolemma bilayer.

[Interaction of immobilized DNA with alkaline metal and ammonium ions].

Ion exchangers with various capacities (0.1-0.2 mg-equiv/g of dry gel) are synthesized by means of immobilization of DNA in polyacrylamide gel. Exchanges of alkali metal cations and ammonium are studied on these exchangers and selectively coefficients are determined. The following selectivity series of immobilized DNA in reference to the above-mentioned cations is stated: Li+ greater than or equal to NH4+ greater than or equal to Cs+ greater than Rb+ greater than K+ greater than or equal to Na+. The peculiar properties of Li+ and NH4+ in this series are noted and a possible explanation of this fact is offered. A supposition regarding the reduced activity of water in the polyacrylamide gel containing DNA is made.
