BACKGROUND & AIM: To investigate the difference of bone marrow chromosome aberrations induced by acute or chronic ionizing radiation with multicolor FISH (M-FISH) method.

Fluorescence in Situ Hybridization Applying to Investigation of Chromosomal Aberrations;

To investigate late effects of ARS,14 years continuous follow-up study of chromosomal aberrations in these 5 victims was performed to accumulate valuable data on late effect of radiation.

MATERIAL AND METHODS: Conventional chromosomal aberrations and G-banded kayrotype analysis were used.

Chromosome aberration types and reproductive humors′s level in azoospermia patients.;

Roles of dirithromycin in the chromosome aberration of CHL cell in vitro;

Effects of sparfloxacin on chromosome aberration of CHL cell in vitro;

Comparison of SCGE and chromosome aberrations for detecting genetic toxicity;

Study on Ionizing Radiation to the Workers′ Lymphocyte Micronucleus Rate and Chromosome Aberrations.;

5--200 mg/kg) have obvious protective effects on primary spermatocyte chromosome aberrations induced by 3.

Research on chromosomal aberrations in human sperm and lymphocyte cell exposed to large dose γ ray;

The recent development of scientific researches on cytogenetic toxicology of arsenic was briefly reviewed,emphasizing on induction effects of arsenic on chromosomal aberrations,sister-chromatid exchanges,and micronuclei in the vivo of human beings,animals tested,and some plants,also in cultured cells from human beings and mammalian animals in vitro.

MATERIALS AND METHODS:The samples of chromosome and CB micronucleus were prepared by using cultured whole blood,and analysis of chromosomal aberrations and CB micronuclei were made in the 6 victims exposed to 60Co radiation accident occurred in Xinxiang of Henan 1-2 years after irradiation.

Several mutant plants were generated from Impatiens balsamina seeds induced by space-flight,and chromosome mutation during meiosis and microspores were investigated in respective mutant plant.
