Effects of HgCl2 (100 microM) para-chloromercuribenzene sulfonate (PCMBS) (1 mM), and oxophenylarsine (OPA) (250 microM) were determined on (a) the rate of Na pump activity in intact winter flounder intestine; (b) activity of Na-K-ATPase in tissue homogenates; and (c) Na-dependent and Na-independent uptake of tyrosine in brush border membrane vesicles.

Moreover, the abundance of the alpha-1 subunit of the Na-K-ATPase was decreased in the cortex/OSOM and ISOM but remained unchanged in the inner medulla.

Since in several tissues including myocardium Hg2+ inhibits the activity of Ca2+ and Na (+)-K (+)-ATPases the results described here suggest that Hg2+, at lower concentrations, could increase force by inhibiting Na (+)-K (+)-ATPase, while at higher concentrations Hg2+ would decrease relative PRC potentiation by inhibiting sarcoplasmic reticulum Ca (2+)-ATPase.

The inhibitory action of Hg2+ on ATP hydrolysis and on Ca2+ and Na (+)-K+ ATPases suggested to occur in other tissues could be the mechanism responsible for the observations reported here.

Pretreatment of cells with 10 microM FCCP, a metabolic inhibitor and a proton ionophore, 0.5 mm DIDS, an anion transport inhibitor, or 0.5 mM ouabain, a Na+/K+-ATPase inhibitor, resulted in 72, 60, and 57% reduction in Hg uptake, respectively.

The effects of HgCl2, CH3HgCl, p-chloromercuribenzene sulfonate (PCMBS), and CdCl2 on plasma membrane and cell metabolic functions of skate (Raja erinacea) hepatocytes in suspension culture were assessed by measuring (a) the rates of Na+-dependent and -independent L-[14C] alanine uptake, (b) Na+-dependent 86Rb+ uptake, a measure of Na-K-ATPase activity, (c) 86Rb+ efflux, a measure of K+ permeability, (d) the difference between the 3H2O and [14C] inulin distribution spaces, a measure of intracellular water volume, (e) cellular ATP concentrations, and (f) glutathione (GSH) and glutathione disulfide (GSSG) levels.
Mercuric chloride also impaired volume regulatory mechanisms in skate hepatocytes: cells treated with 50 microM HgCl2 swelled slowly over a 60-min interval to volumes nearly double those of control cells.

Chronic potassium loading protects against mercuric chloride, uranyl nitrate, and gentamicin models of acute renal failure.
In the gentamicin model, protection is associated with a stimulation of renal cortical Na-K-ATPase activity and a reduction in the level of gentamicin accumulated in cortical tissue.
