Evaluation of the influence of N-nitrosodimethyloamine (NDMA) on the apopto
sis of neutrophils of peripheral blood (PMN) and the expression of the IL-6
R membrane receptor - in vitro research.
The aim of the present work was the evaluation of N-nitrosodimethyloamine (
NDMA) on the induction of apoptosis in the neutrophils of peripheral blood
as well as the evaluation of the surface receptors for IL-6. The isolated n
eutrophils were incubated for 1 and 3 hours with NDMA of a concentration of
2.5, 5, 7.5, and 10 mg/ml. In the samples incubated for 1 hour a significa
nt, dose- dependent increase of apoptosis in the examined cells was observe
d. In the cells incubated for 3 hours, the increase of apoptosis was observ
ed only at concentration of NDMA of 2.5 and 5 mg/ml. In case of higher conc
entration used, probably necrotic processes dominated in the cells. No infl
uence of NDMA on the expression of IL-6R was observed.
