These slides were observed under microscope (Olympus BX 41) (oil immersion) for the presence of micronuclei in 2000 polychromatic erythrocytes (Fig.
The following parameters were analyzed in each specimen: a) the frequency of PCE among the first 100 NCE observed in each slide (PCE/NCE ratio); b) the frequency of micronucleated polychromatic erythrocytes (MNPCE) within 2,000 polychromatic erythrocytes counted; c) the frequency of micronucleated normochromatic erythrocytes (MNNCE) within 2,000 normochromatic erythrocytes counted; d) the frequency of dead cells (DC; erythrocytes with [is greater than] 3 micronuclei in the bone marrow) within 2,000 cells; e) the frequency of micronucleated peripheral blood erythrocytes (MNPBE) within 4,000 erythrocytes; f) the frequency of metaphases among 2,000 cells (MI); and g) the frequencies of cells with chromosome aberrations among 100 metaphases.
To detect MNPCE frequency, we fixed the smears with Giemsa (1:30) (Heddle, 1973), prepared two slides for each mouse, and scored 1000 polychromatic erythrocytes (PCE) per slide.
