Sister chromatid exchange points (SCE points) on individual chromosomes were studied in cultured lymphocytes from 11 monozygotic (MZ) and nine dizygotic (DZ) same-sexed pairs by means of sequential Q-banding and BUdR-Giemsa techniques. No statistically significant variation between unrelated individ

β¦ Synopsis
The SCE frequency was studied in cultures of peripheral lymphocytes from three subjects before and after vaccination against measles. The immunological vaccination reactions were monitored by antibody titration and by measurement of DNA synthesis in peripheral lymphocytes. In two of the subjects, on the 14th day after vaccination, there was a marked decrease of the SCE frequency coinciding with common clinical vaccination reactions and an increase of DNA synthesis in the peripheral lymphocytes. The increase of antibody titers started on the 17th day. One month later, when the immunological reactions had subsided, the SCE frequency was increased by 25% over the prevaccination level. Third subject displayed a delayed vaccination response due to a simultaneous influenza infection. This subject showed a 50% increase in the SCE frequency on the 14th day as well as 6 weeks after vaccination. These results suggest that significant changes in the SCE frequency may be related to immunological vaccination reactions.
