Restoration of nitric oxide production by aldose reductase inhibitor in human endothelial cells cultured in high-glucose medium.

abstract：:Carbachol (CCH), serotonin (5HT), divalent ionophore A23187, cAMP, and certain neuropeptides, i.e. substance P (SP), inhibit the initial rate of uptake (influx) of 22Na into isolated chicken villus enterocytes. All these agents also increase cytosolic Ca. However, the increases stimulated by CCH, 5HT, and cAMP are not...
