MATERIALS AND METHODS: The health-preserving cigarettes were made by certain Chinese herbal medicine such as piper sarmentosum Roxb. We made these cigarettes into a smoke liquid of normal saline solution as an experimental material to do an acute toxicity test in mice. A micronucleus test of mice bone marrow polychromatophilic erythroblast and an Ames test were performed.

材料与方法：在香烟中加入中草药假药等制成中草药保健香烟，用该香烟制得生理盐水烟雾液为实验材料，进行小鼠急性毒性实验、小鼠骨髓嗜多染红细胞微核试验和Ames试验。

MATERIALS AND METHODS: The root tips of Vicia faba were treated with different concentrations of sodium sulfite and sodium nitrite (in the concentrations of 25;50;100;200;400 mg/L) with distilled water as control for four hours.The root tips of Vicia faba were stained with carbol fuchsin and examined. The micronucleus rate and the rate of chromosome aberration were determined within root tip cells of Vicia faba.
