Chromosome counts and karyotypes were prepared from samples of dysplasia and carcinoma in situ of the uterine cervix in 14 patients with the use of tissue culture technics. The material for initial culture was identified as neoplastic epithelium in vivo by colpomicroscopy. Then a biopsy was obtained from within this area; one half was fixed for histologie examination, and in the remaining half,...

Uraeotyphlus oxyurus (Dumeril et Bibron, 1841), Uraeotyphlus interruptus Pillai et Ravichandran, 1999, Uraeotyphlus narayani Seshachar, 1939 and Uraeotyphlus menoni Annandale, 1913 were cytogenetically analysed following conventional and differential staining techniques. These species show similar karyotypes with 2n=36 (FN=58). There were no traces of species-specific features in regard to C-ba...

In chronic lymphocytic leukaemia the majority of circulating lymphocytes which responded to phytohaemagglutinin in vitro were found to have normal karyotypes. A minor population of cells in patients treated with chemotherapy had an increased number of chromosomal rearrangements as compared with cells from normal controls and untreated patients with chronic lymphocytic leukaemia. Probably bonema...
