Aim: To evaluate the interphase ribosomal RNA cistron activity of cardiomyocytes in surgical patients with chronic ischaemic heart disease by means of the nucleolar organiser region silver staining (AgNOR) technique.
Methods: Nucleoli were investigated in myocardial samples obtained from 46 patients with chronic ischaemic heart disease before, during, and soon after cardioplegia ischaemia. Cryostat sections of 10 microns thickness were air dried, fixed in methanol/glacial acetic acid (3:1) for 15 minutes, rinsed carefully with distilled water, incubated in 2 N formic acid for 10 minutes, and impregnated with silver colloid solution for 2.
