Fig 1 A polyacrylamide gel with radiolabelled reverse transcription-polymerase chain reaction (RT-PCR) products from cardiac tissue of a patient with unstable angina undergoing open heart surgery with cardiopulmonary bypass. Biopsies were taken simultaneously from the left atrium (LA), right atrium (RA), and left ventricle (LV) before cardioplegic arrest. Histone H3 (215 bp) was employed as a reference gene to evaluate the relative amount of test genes, which were tumor necrosis factor α (TNFα, 444 bp), interleukin-1β (IL-1β, 464 bp), intercellular adhesion molecule-1 (ICAM-1, 237 bp), E-selectin (CD62E, 255 bp), CD18 (379 bp), CD25 (312 bp), endothelin-1 (ET-1, 725 bp), inducible nitric oxide synthase (iNOS, 532 bp), and endothelial NOS (eNOS, 737 bp).

Fig 2 Gene expression of tumor necrosis factor α (TNFα), interleukin-1β (IL-1β), and intercellular adhesion molecule-1 (ICAM-1) in human heart biopsies from the right atrium (RA), left atrium (LA), and left ventricle (LV) obtained before cardioplegic arrest during open heart surgery. Reverse transcription-polymerase chain reaction (RT-PCR) was performed, band density measured, and the ratio between test gene and reference gene calculated (= relative mRNA). The left panels show mean ± SEM values from 19 patients, and the right panels show mean ± SEM of subgroups of patients with unstable angina (uCABG, n = 7), stable angina (CABG, n = 7), and valvular or combined disease (VR, n = 5).
