ABSTRACT
The capacity of an organophosphate to elicit the acute phase response (APR) was assessed by studying the effects of acute soman intoxication on two major processes which characterize inflammation, cytokine production in macrophages and the expression of acute phase protein (APP) genes in the liver. It was established that the concentration of lymphostimulatory substances secreted by the macrophages of soman-intoxicated rats was increased to a level characteristic of the primary inflammatory reaction. Macrophage activation was followed by increased transcription rates of APP genes and the corresponding mRNA and protein synthesis in the liver. The pattern of the DNA-protein complexes obtained with nuclear extracts and the cis-element of the rat haptoglobin gene in the gel-retardation assay suggested that the molecular events which underlie the expression of APP genes of intoxicated rats are similar to those that occur during the APR. From these findings we concluded that soman intoxication was a metabolic injury which elicited the typical APR.
