-	Lack of association between endothelial constitutive nitric oxide synthase (ecNOS 4 b/a) gene polymorphism and rheumatic heart disease
Our aim in this work was to explore any possible association between ecNOS 4 b/a polymorphism and rheumatic heart disease (RHD). In this study, leukocyte DNA was extracted from 139 patients with RHD and 79 healthy control children. After amplification by PCR, the products were separated by electrophoresis in 6% polyacrylamide gel and visualized after ethidium bromide staining with UV ... إقراء المزيد
