[Use of the micronucleus test in the screening and monitoring of mutagens].

Data from literature on the use of micronuclear test to determine mutagenicity in agents of physical, chemical and biological nature are presented. The objects on which this method is used most frequently are enumerated. Great attention is paid to the analysis of micronuclei in blood erythrocytes and bone marrow of animals. It is shown that the animal sex, age and the way of mutagen injection are of great importance in micronuclear testing of mutagens. Methodical papers concerning the peculiarities of fixation colour, analysis and mathematical testing are given. Mutagen factors tested by the method of micronuclear analysis are enumerated. A high resolution and small labour input of the micronuclear test are shown.
