Abstract
To analyze the changes in CD8(low) T lymphocyte subsets in patients with occupational chronic lead poisoning. Flow cytometric analysis was used to count the numbers of CD8+ cells. 23 patients with occupational chronic lead poisoning and 20 controls were examined. Compared with control group (8.21% ± 3.02%), the CD8(low) T lymphocyte (12.98% ± 5.62%) were significantly increased in patients with occupational chronic lead poisoning. Although the ratio of CD+ T lymphocyte is normal, the CD8 level is significantly decreased. The increase of CD8(low) T lymphocyte may be an important phenomenon of immuno-injury induced by lead. CD8(low) T lymphocyte could be an new direction for research of lead immuno-toxicity.
