The first inhibitor of NHE, amiloride, was identified in 1982. This drug is a potassium-sparing diuretic that also inhibits the sodium-calcium exchanger and the conductive Na+ channel. Not all the NHE isoforms are inhibited equally by amiloride NHE1 and 2 are responsive, NHE5 is partially responsive and NHE3, 4 and 7 are resistant. Other weak and non-specific inhibitors are clonidine and cimetidine. [Pg.811]

The formation of heavy carbonaceous compounds in 5A calcium exchanged zeolites depends on the calcium content. These zeolites are able to protonated ammonia molecules in ammonium ions. This Bronsted acidity results from the presence of CaOH+ species which are formed by water dissociation on Ca2+ ions and have an IR signature at 3515 cm"1. [Pg.108]

In addition to modification of calcium influx/efflux, other mechanisms like inhibition of slow inward current [363] and nickel-calcium exchange [364] have been suggested to explain the positive inotropic effects of nickel. Moreover, these inotropic effects might be mediated by an action of nickel on the outside surface of the cardiac cell membrane, where nickel inhibits the ATP-dependent component of the calcium extrusion, thereby causing contraction-enhancement [364, 365],...

While our data using this technique are still preliminary, we have observed that 25 yU/ml insulin inhibits the rate of calcium efflux from renal slices (28). This effect of insulin was gradually reduced at the higher concentrations of insulin. The effects of insulin on calcium exchange appear to be localized in the mitochondrial compartment. Further work is needed to determine whether insulin affects specific enzyme systems which are known to play a role in renal calcium transport, and which cellular or subcellular compartments are involved. This would substantially increase our understanding of the regulation of urinary calcium excretion, and of ways in which excessive loss of calcium by this route might be avoided. [Pg.123]
