ABSTRACT
Objective To investigate the effect of nitric oxide on hydrogen sulfide/ cystathionine-?-lyase(CSE) system in the vascular smooth muscle cells of spontaneously hypertensive rats(SHR).Methods The SHR aortic smooth muscle cells(SMCs) were divided into 2 groups sodium nitroprusside(SNP) group and control group.The content of hydrogen sulfide in the culture media was measured by sulfide electrode method,and the CSE mRNA level was assayed by competitive reversed transcription-polymerase chain reaction((RT-PCR)).Results Compared with control group,the content of hydrogen sulfide in the culture media of SNP group was significantly higher [(16.16?3.71) ?mol/L vs(22.71?4.84) ?mol/L],and the CSE mRNA level in SMCs in SNP group was lower than that of control group.Conclusion Nitric oxide exerted complicated effect on the hydrogen sulfide/CSE system in the SHR smooth muscle cells.J Appl Clin Pediatr,2006,21(3)140-141
