Analysis of micronucleus frequency and micronucleated cell frequency of lymphocytes in peripheral blood in Foshan Nanhai area

Objective To study micronucleus frequency (MF) and micronucleated cell frequency of lymphocytes in peripheral blood in Foshan Nanhai area. Methods 700 normal physical examination people with different ages and sexes in Nanhai area were selected. According to the resident addresses, the samples were assigned to the seven townships under the jurisdiction of the Nanhai District. Using micro-blood cultures to prepare the samples, the micronucleus frequency and micronucleated cell frequency of lymphocytes in peripheral blood were analyzed. Results The male micronucleus rate was 0.016 2% and micronucleated cell frequency was 0.118%. The micronucleus rate of female was 0.015 7% and micronucleated cell frequency was 0.121%. There was no significant difference between males and females(P>0.05). The upper limit of 95% normal value of micronucleus rate for male and female was 0.184% and that of micronucleated cell frequency was 0.569%. The micronucleus rate in 20-30 years old group and > 30-40 years old group were 0.009
