[Level of uric acid in the blood of healthy subjects and ischemic heart disease patients].

The level of uric acid (UA) was studied in the blood of healthy persons and CHD patients. A total of 428 males aged 40 to 59 were examined. The level of blood UA in CHD patients was much higher than in healthy persons of the same age.

[Complex formation of spin-labeled trideoxyadenylate with polyribouridylic acid].

It is shown that the ESR spectra of triple-stranded complex formed by the polyribouridylic acid with the trideoxyadenylate spin-labelled on terminal phosphate is a superposition of the signals with strongly different width of HFS-components. This result is a structural support of the early proposed supposition about the irregular relative orientations of the oligomers in the triple-stranded complexes of oligoadenylates with poly-U.

[Complex formation of di-oligodeoxyadenylyl-5',5'-pyrophosphatess with polyuridylic acid].

The complex formation of P1,P2-bis-trideoxyadenylyl-, P1-trideoxyadenylyl, P2-hexadeoxyadenylyl and P1,P2-bis-deoxyadenylyl-5',5-pyrophosphates with polyuridylic acid has been studied. It is shown that these compounds form triple-stranded complexes with poly-U, which have much the same absorption and circular dichroism spectra as those of (oligo-dA).2(poly-U).
