Abstract
To examine the association between the functional state of endothelium and bronchial asthma the oxide nitrogen (NO) condition in blood samples was evaluated in 118 bronchial asthma children with a wide range of desease severity with the use of Yemchenko L.N. method (1994) by determination of terminal stabile metabolites, and endothelin-1 (ET-1) concentration with enzyme immunoassays analysis, and also with the use of J. Hladovec method (1978) of circulation endothelial cells (CEC) level establishing. The credible increase of ET-1 (0,525±0,06 fmol/ml), NO (66,59±4,45 mkM/ml), CEC (7,28±0,63 cells/100 mkl) levels in bronchial asthma children compared with control (0,22±0,01 fmol/ml, 29,86±0,77 mkM/ml, 3,03±0,22 accordingly, p<0,01). The levels of endothelial markers credibly decreased on the background of anti-inflammatory therapy by inhalative glucocorticosteroids (NO 82,69±14,38 mkM/ml and 42,12±9,66 mkM/ml, p=0,001; ET-1 0,64±0,15 fmol/ml and 0,35±0,06 fmol/ml, p=0,001; CEC 7,3±1,67 and 5,0±0,32 cells/100 mkl p=0,0017). All the trial results may be used as an additional standard definition of bronchial asthma severity and therapeutic efficiency in bronchial asthma children.
