RESUMEN

Oxygen metabolism of neutrophils was measured using chemiluminescence method in patient with pulmonary tuberculosis. Patients were included into three groups. Group I--20 patients (10 men, 10 women) aged 24-74 years (mean 48.3 years) with pulmonary tuberculosis BK(+). Group II--20 patients (15 men, 5 women) aged 19-67 years (mean 45.1 years) with pulmonary tuberculosis BK(0). The control group consisted 16 clinically healthy persons (12 men, 4 women) aged 28-59 years (mean 42.5 years). Blood samples (5 ml) were collected for examination from cubital vein early morning before breakfast. A luminometer 1251 coupled with an IBM PC AT compatible computer was used for the measurement of chemiluminescence. The chemiluminescence of non-stimulated neutrophils and those stimulated by a receptor stimulus formyl-Met-Leu-Phe (fMLP) as well as an extrareceptor stimulus phorbol myristate acete (PMA) was measured. The results of our study demonstrated that chemiluminescence of non-stimulated as well as stimulated by fMLP and PMA neutrophils was lower in comparison to the values of chemiluminescence in the control group.

RESUMEN

Plasma malonyl dialdehyde (MDA) concentration was determined by Placer method in patients with pulmonary tuberculosis before and during treatment period with tuberculostatic drugs. Patients were divided into three groups. Group I comprised 20 patients (10 men and 10 women) aged 24-74 years (mean 48.3 years) with pulmonary tuberculosis BK(+). Group II comprised 20 patients (15 men and 5 women) aged 19-67 years (mean 45.1 years) with pulmonary tuberculosis BK(0). The control group consisted of 16 clinically healthy persons (12 men and 4 women) aged 28-59 years (mean 42.5 years). In patients blood samples (5 ml) were collected for examination from cubital vein before, after 1-month and 2-month treatment period with tuberculostatic drugs. In the control group blood samples were collected from cubital vein once. Results of our study showed that plasma MDA concentrations in patients with pulmonary tuberculosis, both before and during treatment period with tuberculostatic drugs, were significantly higher, in comparison to the control group.

RESUMEN

In 14 patients with stable angina pectoris we examined the effect of pentoxifyline (PTX) on oxidative metabolism of TNF-alpha-priming neutrophils. The control group consisted of 21 patients with stable angina pectoris without pentoxifylline administration. Blood samples for examination were taken from basilic vein (peripheral blood) and coronary sinus immediately before PTCA procedure. In PTX-group was found the significant decrease in spontaneous CL of TNF-alpha-priming neutrophils from coronary sinus blood (1231.0 +/- 119.4 mV x min), in comparison to the control group (1374 +/- 124.4 mV x min). In PTX-group was found the significant decrease in fMLP stimulated CL of TNF-alpha-priming neutrophils from peripheral blood (4219.0 +/- 707.2 mV x min) and coronary sinus blood (4322.0 +/- 664.4 mV x min), in comparison to the control group (5248.0 +/- 595.8 mV x min and 4973.0 +/- 536.5 mV x min; respectively). There were no differences between both groups in PMA stimulated CL of TNF-alpha-priming neutrophils.

RESUMEN

We estimated adherence, aggregation and chemiluminescence of neutrophils as well as concentrations of C3c, C4 and C5 complement components and complement haemolytic activity (CH50) in 27 patients with unstable angina pectoris subjected to percutaneous transluminal coronary angioplasty (PTCA). The control group consisted of 12 patients with unstable angina pectoris, in whom coronary angiography was performed but PTCA was decided against for various reasons. Blood samples for examination were taken from coronary sinus and peripheral vein just before, 1 min and 20 min after PTCA or coronary angiography. We observed enhancement of neutrophil adherence, aggregation and chemiluminescence, and decrease in concentrations of C3c, C5 and complement haemolytic activity (CH50) after PTCA procedure. In conclusion we think that ischemia resulting from PTCA causes complement activation in an alternative pathway which seems to be connected with neutrophil activation.

RESUMEN

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.

RESUMEN

The adherence and aggregation abilities of neutrophils (PMNs) were evaluated in thirty three patients with unstable angina, who were qualified for PTCA procedure. The control group consisted of forty one clinically healthy persons. The blood for investigations was obtained from coronary sinus and basilic vein just before the procedure, while in the control group from basilic vein only. The adherence of PMNs to plastic surface (rest and stimulated by PMA) was estimated in vitro according to Oez's et al. method by measuring optical density of generated formazan, whereas the aggregation of PMNs was evaluated using the leukergy test according to the method of Fleck in Berliner's and Aronson's modification. In patients with unstable angina statistically significant higher (p < 0.001) adherence of peripheral blood PMNs, compared with control groups was found (patients: rest-0.525 +/- 0.245, stimulated-0.839 +/- 0.419, control group: rest-0.260 +/- 0.129, stimulated-0.522 +/- 0.377). The aggregation of peripheral blood PMNs was significantly higher (p < 0.05) in the sick than in the control group (the sick-10.98 +/- 4.29%, controls-4.65 +/- 3.01%). No differences in investigated parameters of PMNs obtained from peripheral or coronary sinus blood were found.
