Abstract
49 suspensions with cells of the cervix uteri exclusively taken from postmenopausal women were analysed with the pulsecytophotometer. 7 of these cases had an histologically verified invasive cancer of the cervix uteri. There were no false negative results, the percentage of false positive measurements was about 30%. This good result may arise from selecting the cell material analized exclusively from postmenopausal patients and the choice of mathematical model for histogram interpretation, which has been constructed analogously to the cycle of mitosis of cells. Comparing the different methods of preparation of the suspensions the standard procedure (RNase, pepsin, ultrasonic) before staining with ethidium bromide seems to be the best one.
