Abstract

Addition to tobacco of phenylmethyloxadiazole (PMO) protects rats against some of the adverse effects of exposure to cigarette smoke. Two groups of 15 rats were exposed to 25 cigarettes a day for 24 days; the group whose cigarette included PMO showed less immediate distress after exposure, a smaller tracheal goblet cell count, less thickening of the tracheal epithelium, and less cells in mitosis than those exposed to ordinary tobacco.

摘要

在烟草中添加苯甲基恶二唑(PMO)可保护大鼠免受接触香烟烟雾的一些不利影响。两组各15只大鼠每天暴露于25支香烟中,持续24天;香烟中含有PMO的组在暴露后表现出的即时痛苦较轻,气管杯状细胞计数较少,气管上皮增厚较少,处于有丝分裂的细胞也比暴露于普通烟草的组少。
