DNA-PLOIDY ANALYSIS OF BREAST-TUMOR CELL BY THE SYSTEM OF HADAMARD-TRANSFORM MICROSCOPIC IMAGE-ANALYSIS

Normal human lymphocyte was used as standard diploid cell, acridine or ange was used as fluorescence probe for DNA in cell, and DNA ploidy of six cases of human breast tumor was analyzed by the system of Hadamar d transform microscopic image analysis, Some parameters were employed to evaluate tumor malignancy, the results are concordant with patholog ical diagnosis, this indicates that the above instrument may be applie d in diagnostic and prognostic study on human breast cancer, The resul ts also show that significant positive correlation exists between tumo r cell nuclear DNA ploidy and its area (pixels).
