Aniline induces lipid peroxidation and protein oxidation in the spleen and that oxidative stress plays a role in the splenic toxicity of aniline. The hematopoietic system is the primary target of aniline insult in rats which is characterized by methemoglobinemia, hemolysis, and hemolytic anemia and by the development of splenic hyperplasia, siderosis, fibrosis, a variety of sarcomas, and, most commonly, fibrosarcomas on prolonged exposure. Many of the characteristics of splenotoxicity in rats, such as hyperplasia, hyperpigmentation, and/or formation of highly malignant tumors such as fibrosarcomas, are not restricted to aniline exposure, but also occur when animals are exposed to substituted anilines such as chloroaniline. Studies with aniline hydrochloride in rats indicate an association between erythrocyte damage and the severity of the splenotoxicity. Since one of the major functions of the spleen is to remove damaged erythrocytes, aniline-damaged erythrocytes would be expected to be scavenged by the spleen, especially by phagocytes. The deposition and subsequent breakdown of damaged erythrocytes will not only release aniline and/or its metabolites, but, most importantly, will also result in accumulation of iron in the spleen which may catalyze the generation of tissue-damaging oxygen radicals which can subsequently cause oxidation of biomolecules and result in lipid peroxidation and protein oxidation. It is also possible that during the scavenging of damaged erythrocytes, the splenic phagocytes, especially macrophages themselves, can become activated and release reactive oxygen species (ROS) which could further contribute to the oxidation of biomolecules leading to tissue injury.
