Therefore using the acute toxicity,cumulative toxicity,mice polychromatic erythrocyte micronucleus rate(PCE MNR) and sperm abnormal rate of the genetic toxicity as markers,we tested the toxicity of the Tibet kefir milk.

This experiment was conducted to study the influence of Ascot Courage Liquid on the ejaculate volume and sperm abnormal rate in boar.

By means of making and observating some instant sections,checking percentage of misshapen spermatozoon in the seminal fluid.

MATERIAL AND METHODS: Acute toxicity test,bone marrow cell micronucleus test,mice sperm abnormality test and30d feeding study were performed to study the toxicity of pollen pini.

MATERIAL AND METHODS: The micronucleus test of mouse bone marrow cell and the sperm abnormality test in rats were used in this study.

Objective: To study the effects of astragalus membranaceus injection on sperm abnormality in Cd-induced rats.

In order to know the safety of Tai-Ke-Fen Hand Disinfectant Solution, acute oral toxicity, cumulative toxicity, skin irritation, mouse bone marrow polychromatic erythrocyte micronucleus and sperm deformity tests were carried out.

Meth-ods Sperm deformity test and testes chromosome aberration test were used in the studies.

Purpose and Methods: The mutagenicity of heavyweight aromatic hydrocarbon (HAH) was studied by Ames test, micronucleus test and sperm deformity test in mice, sister chromatid exchange test in human beings.
