    Streszczenie angielskie: Background: There is increasing evidence that cytokine-inducible leukocyte-endothelial adhesion molecules are instrumental in the postoperative inflammatory response following cardiopulmonary bypass (CPB). L-selectin was shown to be one of those neutrophil-endothelial cell adhesion molecules. This study aimed to ivnestigate the relationship of teh soluble adhesion molecule, sL-selectin, and the postoperative course in children undergoing CPB. Material/Methods: To determine the time course of sL-selectin after CPB, serial blood samples of 9 children undergoing CPB were collected from the arterial line or from the bypass circuits preoperatively, on initiation of CPB and 1, 6, 12, 18, 24, and 48 hours postoperatively. Plasma was recovered immediately, aliqoted and frozedn at -70řC until use. Circulating sL-selectin molecules were measured witha sandwich enzyme-linked immunoabosrbent assay (ELISA) technique. there were significant changes in plasma levels of sL-selectin in patients following CPB, and these levels were associated with patient characteristics, operative variables and postoperative course. Low values of sL-selectin significantly correlated with inotropic support, low PRISM score, postoperative hypotension and fever. There was a significant association between the development of postoperative sepsis and low sL-selectin levels. No correlation was found between sL-selectin values and lactate concentration or neutrophil fount. Conclusions: Our results suggest a relation between CPB-induced mediators and both early and late clinical effects...

    Streszczenie angielskie: Background: The effects of long-term estrogen (E2) replacement therapy (ERT) on circulating and bone marrow total plasma nitric oxide (NOx) levels were determined in rhesus monkeys. In addition changes in circulating NOx during the menstrual cycle were measured. We measured Nox levels in 20 ovariectomized animals and 27 cycling animals. In the first group monkeys were ovariectomized (OVX; n=10) and treated with estrogen implants for 21 months. The control group (n=10) was OVX and received vehicle implants only. After 21 months systemic NOx status was measured. In a second group of cycling animals NOx was measured during the follicular and luteal phases, and correlated whit body comparison parameters determined by dual energy X-ray absorptiometry (DXA) analysis. Results: Replacement of estrogen in OVX monkeys resulted in reduced circulating but not bone marrow plasma NOx compared to OVX monkeys. Circulating NOx levels in these animals correlated negatively (rý= -0.35; P=0.03) with estradiol levels. In cycling monkeys luteal levels of NOx were found to be significantly higher than follicular levels and correlated negatively (rý=-0.4; P=0.036) with estradiol but not progesterone levels. Negative correlations between NOx levels and body weight, fat and lean mass were also found. Conclusion: Long-term ERT influences systemic NOx levels in negative fashion without effects on bone marrow plasma NOx. Circulating NOx was higher during the luteal phase. In both ERT treated and cycling monkeys estradiol co\related negatively with NOx suggesting the existence of a negative...
