мазки на онкологию шейки матки

Регуляторная the area virus генома (upstream regulatory region, URR) settles down between the end of area of late genes and the beginning of area of early genes. Open frameworks of reading ORF генома a virus are divided{shared} on early (early, Е) and late (late, L) sites. The early fragment includes genes Е1-Е7 coding synthesis of fibers, responsible{crucial} for various functions in process репликации a virus and transformation of cells{cages}. Genes Е1 and Е2 are responsible{crucial} for репликацию a virus, and also participate in regulation of a transcription virus генома. The product of gene Е1 is responsible for maintenance персистенции virus генома in эписомальной to the form. Gene Е2 codes products which can as a trance - activate, and to suppress экспрессию early genes and энхенсерных sites URR. Трансактивирующий the factor is identified in precancer changes шейки a uterus, репрессирующий the factor in vivo is not identified [16]. Gene Е4 participates during maturing virus particles, genes Е5-Е7 possess трансформирующим potential. Genes Е6 and Е7 are always defined{determined} and экспрессируются in tumours шейки a uterus and received of tumours шейки a uterus cellular lines. The biological effect трансформирующего potential of genes Е6 and Е7 will be considered below. The late fragment генома will consist of genes L1 and L2, coding structural fibers вириона [5,21].

The data on influence of long steroid contraception on frequency дисплазии and a cancer шейки a uterus разноречивы. Insignificant increase in frequency дисплазии and преинвазивного РШМ at the women using steroid contraceptives, have noted Andolsek with соавт. (1983), Piper (1985.) Svan and Brown (1981), Vassey with соавт. (1983) have defined{determined} relative risk РШМ equal 1,5 and 2,5 accordingly, in other researches it is not marked correlations between application of hormonal contraceptives and РШМ [3]. Experts the CART (Geneva, 1985) Came to a conclusion, that the treatment of the data on use of steroid contraceptives is inconvenient as because of the big number of preparations and absence of the authentic cytologic control over a condition эпителия шейки a uterus prior to the beginning and during application of steroid contraceptives, and owing to interrelation of frequency of application of contraceptives and sexual activity. Now there are convincing data on raised{increased} risk РШМ at smoking щенщин. Hellberg with соавт. (1983), Greenberg with соавт. (1986), Winkelstein (1985), Brinton (1986) mark association of smoking with the early beginning of a sexual life and often change of sexual partners, Hoffman with соавт. (1985), Sasson with соавт. (1985) suppose to a - cancerogenic role contained in a tobacco smoke of nicotine and котинина [4]. Подробнее...
