Technical Report On Toxicology And Carcinogenesis Studies Of Methylene Blue Trihydrate Cas No 7220 79 3 In F344 N Rats And B6c3f1 Mice Gavage Studies

Methylene Blue Trihydrate (MBT) has a variety of biomedical and biologically therapeutic applications. MBT was nominated by the Nat. Cancer Inst. for carcinogenecity testing based on the numerous uses of this compound and the lack of long-term toxicity data, including epidemiological studies of MBT, as well as the inadequate animal data on this compound. Male and female F344/N rats and B6C3F1 mice were administered MBT in 0.5% aqueous methylcellulose by gavage for 1 month, 3 months, or 2 years. Genetic toxicology studies were conducted using ¿Salmonella typhimurium,¿ ¿Escherichia coli,¿ cultured Chinese hamster ovary cells, mouse bone marrow cells, and mouse peripheral blood erythrocytes.

a-Methylstyrene is used to make heat-resistant acrylonitrile-butadiene-styrene resins & polymers. This report studies the effects of a-methylstyrene on male & female rats & mice to identify potential toxic or cancer-related hazards. It concludes that exposure to a-methylstyrene in the air caused kidney tumors, & possibly mononuclear cell leukemia, in male rats. It concludes that a-methylstyrene caused liver cancer in female mice, & also possibly in male mice. Charts, tables, graphs & plates.

The latest edition of this text provides a comprehensive overview of the “natural flow of knowledge” regarding inflammatory bowel disease, with an emphasis on state-of-the art approaches that should be the basis for diagnosis and treatment of most patients. In addition to updated chapters, this volume includes new chapters on such topics as the impending biosimilar revolution, quality of care, and new challenges to previously held beliefs about IBD diagnosis, treatment, and pathogenesis. The book is also one of the first to have a chapter written specifically by and for physician extenders in the training of colleagues and the treatment of patients, which is of increasing importance moving forward in the medical profession. Written by experts in the field, Inflammatory Bowel Disease: Diagnosis and Therapeutics, Third Edition is a valuable resource for physicians, nurses, researchers, and other health care providers interested in the latest cutting-edge knowledge for treating patients with inflammatory bowel disease.
