Norbormide is a toxicant selective for rats to which it induces a widespread vasoconstriction. In a recent paper. we hypothesized a role of ATP-sensitive potassium (KATP) channels in norbormide-induced vasoconstriction. The current study was undertaken to verify this hypothesis by comparing the effects of norbormide with those of glibenclamide. https://foldlyers.shop/product-category/measurement/
