苯并(a)芘(B(a)P)是煤焦油、煤烟及其它不完全燃烧(如汽车尾气、吸烟等)的产物,是广泛存在于环境中的污染物,研究B(a)P的免疫毒性,对深入了解其对机体的远期危害及致癌机理,寻求B(a)P安全评价的指标具有一定的意义。本文仅就一次腹腔注射B(a)P后对小鼠体液免疫功能、细胞免疫功能及巨噬细胞功能影响做一初步报道。 Benzo (a) pyrene (B (a) P) is a product of coal tar, soot and other incomplete combustion (such as automobile exhaust, smoking, etc.) and is a pollutant widely existing in the environment. P immunotoxicity, to understand their long-term damage to the body and carcinogenic mechanism, to seek B (a) P safety evaluation of the indicators have a certain significance. This article only for a single intraperitoneal injection of B (a) P on the humoral immunity, cellular immune function and macrophage function in mice to do a preliminary report.
