Metabolic alkalosis following administration of an organophosphorus compound, O,S,S-trimethyl phosphorodithioate.

The oral administration of a single dose of O,S,S-trimethyl phosphorodithioate (OSSMe) to rats was found to result, 24 hours after treatment, in a dose-related metabolic alkalosis. Non-invasive indices of kidney damage revealed that during the first 4 hours after OSSMe administration there was a fourfold increase in urine flow with increases in albumin, beta 2-microglobulin and N-acetyl-glucosaminidase excretion. These results suggest that OSSMe-induced metabolic alkalosis may result from early renal functional disturbances.
