| 内容記述 | The effects of the commonly-used intravenous anesthetics, ketamine and thiopental (10^<-5>, 3x10.^<-5>, and 10^<-4>M), on vasorelaxation induced by polymorphonuclear leukocytes(PMNLs) were investigated using the porcine coronary artery. Ketamine, 10^<-4>M, enhanced the PMNLs-induced vasorelaxation, whereas thiopental had no effect. Katamine in concentrations over 10^<-4> M increased the appearance of a cell adhesion molecule, L-selectin(CD62L) on PMNLs measured by flow cytometer. Concanavalin A(Con-A) and lens culinarins agglutinin (LCA), which are kinds of lectin, caused endothelium-dependent vasorelaxation. The PMNLs-induced vasorelaxation was abolished in KCI(25mM)-contracted and ouabain(10^<-5> M)-treated preparation s, and was attenuated by 10^<-2> M tetreathylammonium(TEA), 10^<-2> M tetrabutylammonium (TBA), and 10^<-7> M charybdotoxin(ChTx), but not by 10^<-3> M 4-aminopyridine and 10^<-6> M glibenclamide. The relaxation by Con-A and LCA was also attenuated by TEA and TBA. The findings suggest that PMNLs-induced vasorelaxation is at least in part produced through the calcium dependent potassium channel. However, the facilitation of Na^+ pump cannot be excluded in the mechanism of vasodilation by PMNLs. Oxygen free radical scavengers, superoxide dismutase (150 U/ml), catalase (1200 U/ml), and manittol (80mM) had no influence on the PMNLs-induced vasorelaxation. These findings suggest that lectins induce vasorelaxation partly through calcium dependent potassium channel, and also that ketamine-induced enhancement of the relaxation by PMNLs is produced by increased appearance of L-selectin. | |||||
