Study of nucleolar organizer in women with galactorrhea, or polycystic ovaries, or using oral contraceptive.

ABSTRACT

In this paper we report on changes of the Ag-stained NOR (Ag-NOR) and Ag-stained acrocentric association (Ag-AA) frequencies in lymphocytes of women with polycystic ovaries, galactorrhea, or taking oral contraceptives. The results showed that Ag-AA frequencies were increased significantly in all three study groups while the Ag-NOR frequencies apparently did not increase. We assume that a difference in average Ag-NOR frequency between the two groups may be a measure of the change in the number of active rRNA genes, and that differences of Ag-AA frequency among populations reflect the change in transcriptional rate of the active rRNA genes.
