[The morphofunctional characteristics of proteins of nucleolar organizers in uterine smooth muscle tumors].

Abstract

The authors have shown the activity of argyrophylic nucleolar organizer region proteins (Ag-NOR-proteins) in the uterine leiomyomas of varying histological structure and determined their relationship to the growth rate, size, and site of a node and endometrial pathology. The investigation indicat yomas with significant sclerosis, 4.32 +/- 0.1 in simple leiomyomas, and 6.2 +/- 0.2 in cell leiomyomas (r = 0.58). In menopause, myomas with significant sclerosis and hyalinosis were characterized with a small number of Ag-NOR (1.44 +/- 0.04). Thus, the organizers numbered 12.1 +/- 0.5 and 21.7 +/- 1.0 in high- and low-grade sarcomas, respectively, which may be used in the differential diagnosis of cellular, bizarre, mitotically active leiomyomas and leiomyosarcomas.
