Metabolic activation and lung toxicity: a basis for cell-selective pulmonary damage by foreign chemicals.

abstract：:[35S]t-Butylbicyclophosphorothionate or [35S]TBPS is an improved radioligand for the picrotoxinin binding site in rat brain synaptic membranes. The toxic isomers of the hexachlorocyclohexanes, polychlorobornanes, and chlorinated cyclodienes displace [35S]TBPS with a stereospecificity and potency generally correlated w...
