    Abstract:
    The generation of O2-. and H2O2 by neutrophils (PMNs) obtained from peripheral and coronary sinus blood was investigated in twenty four patients with unstable angina, who were qualified for PTCA procedure. The control group consisted of twenty one clinically healthy persons. The blood for the investigations was obtained from coronary sinus and basilic vein just before the procedure, while in the control group from--basilic vein only. In patients with unstable angina statistically significant higher (p < 0.05) O2-. generation by peripheral blood PMNs (at rest and stimulated), compared with the control group, was found respectively (the sick: rest--11,09 +/- 1.92; stimulated--25.48 +/- 5.76 nmol/cell/min.; healthy: rest--7.98 +/- 1.06; stimulated--13.58 +/- 1.19 nmol/cell/min). No significant differences in O2-. generation between PMNs obtained from coronary sinus or peripheral blood were found. No differences in H2O2 generation by rest PMNs obtained from coronary sinus or peripheral blood were found in patients compared with the control group. The generation of H2O2 by PMA stimulated PMNs was higher in the sick without statistical significance.
