Abstract Using death as an endpoint, it has been demonstrated that tetrachloroethylene (TCE) produces a greater-than-additive effect when given orally in combination with several other compounds. We have attempted to determine more sensitive indicators which would respond in a synergistic fashion when animals are exposed by inhalation to combinations of organic solvents. Male rats were exposed for 4 hr to various concentrations of TCE, dioxane, butyl ether (BE), acetonitrile (ACN), trichloropropane (TCP), and dichloropropane (DCP). The serum enzymes, glutamic oxalacetic transaminase (SGOT), glutamic pyruvic transaminase (SGPT), glucose-6-phosphatase (G-6-Pase), and ornithine carbamyl transferase (OCT) were measured in rats prior to exposure, immediately after exposure, and at 24 and 48 hr after exposure. The enzymes, SGOT, SGPT and OCT, were markedly elevated as a result of exposure to the above compounds, whereas G-6-Pase was only occasionally altered. Neither TCE in combination with dioxane, BE, or ACN nor TCP with DCP resulted in a greater-than-additive effect. On the contrary, in many instances the effects were significantly less-than-additive when tested for interaction.
