[Experimental inflammation after subchronic treatment with Nabam in the rat].

Inflammatory response to turpentine-induced granuloma components was studied in rats receiving 100 ppm Nabam (N,N'--ethylene--bis)dithiocarbamate) disodium) with food for one month. Results of nutritional, clinical and histopathological studies showed no modification. However, administration of Nabam modified the amounts of various mucopolysaccharides, which are important components of the inflammatory response; the amounts of total mucopolysaccharides, glucuronic acid mucopolysaccharides and sialic acid mucopolysaccharides were obviously lowered in treated animals, a symptom of impairment of the inflammatory response. When most classical means of investigation provide only little information, this test could allow toxicologists and nutritionists to evaluate the organisms reactivity to insidious toxic aggression.
