Abstract
Ketamine is an N-methyl-D-aspartate receptor antagonist with rapid antidepressant effects. Studies suggest that inhibition of nitric oxide synthesis plays a role in the mechanism of action of ketamine. This randomized, placebo-controlled study investigated whether co-administration of sodium nitroprusside, a nitric oxide donor, compared to placebo, would attenuate the antidepressant and dissociative effects of ketamine. Sixteen ketamine responders were randomized to a double-blind infusion of ketamine co-administered with placebo or sodium nitroprusside. Our findings show no difference between the two conditions suggesting that the nitric oxide pathway may not play a primary role in ketamine's antidepressant or dissociative effects. The study is registered at clinicaltrials.gov (NCT03102736).

Abstract
Potassium adaptation involves the development of the ability of the kidneys to secrete large amounts of potassium into the urine. This is accompanied by an adaptive increase in the specific activity of sodium-potassium-ATPase in the kidney, predominantly in the medulla and the papilla, but also involving the cortex. It is likely that these changes are localized to the distal tubule and are especially marked in the collecting ducts although there is no direct evidence bearing on this. Net secretion of potassium in isolated kidneys taken from chronically potassium loaded animals is completely eliminated when ouabain, a specific inhibitor of sodium-potassium-ATPase, is added to the perfusion medium. The secretion of potassium appears also to depend critically on the availability of glucose as substrate.
