OBJECTIVE: To observed the chromosome damage of human bronchial epithelial cells induced by glycidyl methacrylate (GMA).
METHODS: Chromosome aberration analysis of human bronchial epithelial cells treated with GMA at different dosages (4, 8, 12, 16 and 20 microg/ml), times (1, 2 and 3 times), and phases (10th, 30th genetation) was detected.
RESULTS: In the dosages range from 4 to 20 microg/ml, the aberration rates (3%, 6%, 7%, 11% and 14%) were demonstrated increasingly with the increase of exposure doses, and dose-effect relationship was found. Significant differences were observed when treated with GMA three times (6%, 7% and 10%). Structure aberrations were found in the transformed 10th-generation cells, while number aberrations were mainly manifested in the transformed 30th-generation cells.
CONCLUSION: The chromosome aberration can be induced by GMA in the human bronchial epithelial cells, from the structure aberration at the beginning to the lack of normal nuclear style.
