Abstract
Autoradiographic and liquid scintillation counting techniques were utilized to measure the ultraviolet (UV)-stimulated incorporation of radioactive thymidine during repair replication of the UV-damaged deoxyribonucleic acid (DNA) of irradiated peripheral blood lymphocytes from 4 patients w ith xeroderma pigmentosum (XDP) and from normal donors. Lymphocytes from 3 of the 4 patients had a markedly decreased rate of incorporation soon after irradiation in comparison with the rate obtained with normal donors' lymphocytes. However, the duration of incorporation into these 3 patients' lymphocytes was prolonged, so that XDP lymphocytes appear eventually to incorporate as much total thymidine as normal lymphocytes. Lymphocytes from the fourth patient had a rate and duration of thymidine incorporation after irradiation similar to normal lymphocytes. This patient, therefore, may have a different genetic and biochemical defect from the other XDP patients
