[The effect of pentoxifylline on oxidative metabolism in neutrophils primed with tumor necrosis factor alpha in patients with stable angina pectoris].

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.
