[The study of markers of herpes virus infections in myocardial ischemia].

A group of patients with ischemic heart disease (IHD), who underwent surgical aorta-coronary vascular shunting, was examined in this investigation. Low titers of HSV-1 specific IgG were detected in all patients, the obtained values being consistent with similar data obtained in healthy subjects of the same age. Negative PCR of HSV-I DNA in blood and biopsy results were obtained. None of the patients demonstrated typical clinical pattern of infectious disease caused by herpes simplex virus. These data are evidence of the absence of the HSV-1 correlation with coronary atherosclerosis in patients with the IHD diagnosis. The significance of HCMV specific IgG titers and HCMV DNA detected in blood plasma in 87.7% cases is probably attributed to existence of connection of HCMV infection markers revealing in patient' blood with IHD diagnosis and coronary atherosclerosis. Besides, the HCMV DNA presence in biopsy taken from myocardium or vascular wall with lesion is revealed in 100% cases. The cytomegalovirus markers in tissue lesions with the help of specific antiserums marked to HSMV recombinant proteins are also revealed in 100% cases. This fact indicates the connection between pathological atherosclerotical process in IHD and cytomegalovirus infection.

[Study of herpes viruses in the blood of patients with cardiovascular pathology]. / Issledovanie gerpesvirusov v krovi bol'nykh s serdechno-sosudistoi patologiei.

The association between Cytomegalovirus (CMV) and Herpes simplex (HSV-1), on the one hand, and the coronary heart disease and chronic venous insufficiency (CVI), on the other hand, was studied; besides the infection rate by the above viruses in different age groups of donors was examined. The following methods--immune-enzyme analysis and detection of viral DNA by means of the polymerase chain reaction (PCR) as well as immune-fluorescence scanning of atherosclerotic plaques--were made use in the study. The pathogenesis of coronary heart disease was shown to be related with the viral contamination caused by CMV, while there was no such correlation between the former and the CVI patients. Finally, it was established that, with age, the frequency rate of seropositive reactions to CMV and HSV-1 was increasing in virtually healthy people.

The levels of phosphomonoesterases (acid and alkaline) in chorions of born placenta, measured by the histochemical method, reflect various phases of the pathological process in gestosis. Adaptive changes in the structure and function, paralleled by increased phosphomonoesterase activities, are replaced by decompensation, formation of destructive and necrobiotic processes, combined with suppressed phosphomonoesterase activities in stubborn severe complications of pregnancy.

[Increased content of nucleotide sequences in transcriptionally active DNA and poly(A)+-mRNA of the rat liver and a rise in its translation activity as affected by inducers]. / Vozrastanie soderzhaniia nukleotidnykh povtorov v transkriptsionno aktivnoi DNK, v poliA+-mRNK pecheni krys i uvelichenie ee transliatsionnoi aktivnosti pod deistviem induktorov.

Cortisol and 3'-methyl-4-dimethyl-amino-azobenzene induce an increase in the content of repeated sequences (RS) in transcriptionally active (TA) DNA, while the content of respective RS in potentially active DNA fractions enriched with regulatory regions of the genome decreases. RS content in induced poly A+-mRNA also rises, as determined by the nature of hybridization of respective c DNA with total DNA. The translation of induced poly A+-mRNA rises essentially, with the qualitative distinctions in in vitro synthesized protein product spectrum being absent. Inducible RS with unstable chromatine conformation are thought to provide a universal system of rapid response of the genetic apparatus to extreme situations, serving as transcription intensifiers in TA DNA and as translation intensifiers in induced poly A+-mRNA.
