Comparative effects of N-acetyl-L-cysteine and ramipril on arterial hypertension, insulin resistance, and oxidative stress in chronically glucose-fed rats.

abstract：:The purpose of this study was to elucidate the mechanism whereby a potassium infusion led to an elevation in the urine minus blood (ohm-B) PCO2 difference in alkaline urine of the rabbit. Rabbits given 9alpha-fluorohydrocortisone 16 h prior to study had a significantly high olm-B PCO2 than control rabbits. However, th...
