Показатели тканевой фибринолитической системы при злокачественной трансформации яичников

Abstract

The activity of plasminogen and plasmin was studied in samples of malignant tumor tissue of bilateral and unilateral ovarian cancer (cystadenocarcinoma stage III, 35 patients) with contralateral ovary unaffected (20 patients), and of ovaries removed during the operation on hysteromyoma (conventionally intact, 18 patients) by the IFA and spectrophotometric methods. It has been demonstrated that malignant ovarian tumor tissue is characterized by disorders in plasminogen-plasmin system: the level of plasminogen is reduced due to increased formation of plasmin. Meanwhile, the contralateral ovary having no morphological signs of malignant transformation displays the same disorders in the plasminogen-plasmin system, as the tissue of the ovary affected by malignant tumor. Notably, it is in the right ovary that rise of activity of plasmin is more significant in cases of right-sided and bilateral malignant process, which quests for further study.

В образцах ткани злокачественных опухолей при двустороннем и одностороннем раке яичников (цистаденокарциномы IIIстадии, 35 больных), контралатеральных непораженных (20 больных) и яичников, удаленных во время операции по поводу миомы матки (условно интактные, 18 пациенток) изучали активность плазминогена и плазмина методом ИФА и спектрофотометрическим. Показано, что ткань злокачественной опухоли яичников характеризуется нарушениями в системе плазминоген-плазмин: снижением уровня плазминогена в силу повышенного образования плазмина. При этом контралатеральный яичник, не имеющий морфологических признаков злокачественного перерождения, имеет такие же нарушения в системе плазминоген-плазмин, как и ткань пораженного злокачественной опухолью яичника. Следует отметить факт более значимого повышения активности плазмина при правостороннем и двустороннем злокачественном процессе именно в правом яичнике, который требует дальнейшего изучения.
