ABSTRACT
Objectives To observe the frequencies of mutations at glycophorin A(GPA)of erythro-cytes in patients with high arsenic coal poisoning(HACP)in comparison with normal controls.Methods The peripheral erythrocytes were isolated and immunolabelled,and were detected by flow cytometry in40patients and18normal adults.Results The mutation frequencies(MF)were(21.23?13.97)?10 -6 for type NN,(33.13?25.72)?10 -6 for type NO,(110.90?63.58)?10 -6 for type MM,and(20.35?21.26)?10 -6 for type MO of erythrocytes in patients with HACP,which were significantly higher than those in normal controls.The mutation frequencies were(31.50?16.13)?10 -6 for type NN,(54.50?38.13)?10 -6 for type NO,(159.33?66.22)?10 -6 for type MM,and(45.16?12.69)?10 -6 for type MO of erythrocytes in tumor group of HACP patients,which were significantly higher than those of non-tumor group of the patients.Conclusions Arsenic poisoning may induce the mutation at the glycophorin-A locus of erythrocytes,sug-gesting that arsenic may be one of potential mutagens.GPA-MF may serve as a parameter for the detection of patients with HACP.
