Comparative reduction of 1-nitro-3-nitrosopyrene and 1-nitro-6-nitrosopyrene: implications for the tumorigenicity of dinitropyrenes.

abstract：:When injected into female NMRI mice tumour necrosis factor-alpha (TNF) produced a dose-related weight loss over the first 24 h, which was accompanied by and directly proportional to a decrease in both food and water intake. Body composition analysis after the first 8 h revealed that the weight loss was associated with...
