ABSTRACT
AIM:
To study the effects of Hydrogen Peroxide(H2O2)and 11,12-epoxyeicosatrienoic acid(11,12-EET)on EDHF-mediated relaxation in the rat basilar arteries.METHODS:
The relaxant effects of acetylcholine(ACh),H2O2,11,12-EET,and catalase(CAT) on rat arteria basilaris in vitro were detected by vasomotoricity experiment in vitro.RESULTS:
In the rat basilar arteries,preconstricted by 30 mmol/L KCl in vitro,ACh(10-7-10-4.5 mol/L) had the concentration-dependent relaxation effect.3?10-5 mol/L N?-nitro-L-arginine-methyl-ester(L-NAME) and 10-5 mol/L indomethacin(Indo) could partly inhibit the relaxation effect of ACh to the rat basilar arteries,but non-No/non-PGI2-mediated relaxation was still significant(P
