The results showed that the CD was found in 27 health donors, with its positive rate being 45% （27/60）. The CD ratio was between 0 and 0.000308%, and not affected by age and gender in sixty healthy donors. Our studies indicate that the CD ratio is low, and do not show the age-dependent accumulation and any gender difference in peripheral whole blood from the normal Chinese population.展开更多
