DOWN\'S SYNDROME: CYTOGENETIC STUDIES IN 150 CASES IN TEHRAN
Cytogenetic studies were performed on 150 cases of Down's syndrome (DS) in Iran. The standard trisomy 21 was found in 132 (88 % ) and translocation-trisomy 21 (+21) in 18 (12%) patients, i.e., t(21,21) in 1(0.63%) and mosaicism in 17(11.33%) cases. The comparison of the frequencies for mosaicism between different populations such as Denmark, Hungary, Egypt, Iraq, India, Australia and Iran ...
متن کاملCytogenetic studies in myeloma.
Chromosomes have been studied in cultures of nucleated peripheral blood cells in 30 patients with myeloma. Both unstimulated cultures and cultures stimulated by phytohemagglutinin (PHA) were examined in all cases. Mitoses were observed in 13 unstimulated cultures of peripheral blood from 12 cases, providing evidence for the presence of circulating abnormal cells in these patients. In 19 stimula...
متن کاملCytogenetic studies in amenorrhea.
OBJECTIVE To study the frequency of the chromosomal abnormality (CA), referred for karyotyping, and counseling in individuals with primary amenorrhea (PA) and secondary amenorrhea (SA). METHODS We report on a retrospective survey of 865 women with amenorrhea (620-PA and 245-SA) at the Division of Human Genetics, Department of Anatomy, St. John's Medical College, Bangalore, India from 1973 to ...
متن کاملCytogenetic Studies in Crossbred Pigs
Karyological investigation pertaining to 30 crossbred pigs (both sexes) maintained at AICRP, Tirupati was undertaken in order to study the chromosomal profile of the crossbred pigs and their morphometric measurements. The cells had the usual diploid complement of 38 chromosomes (2n = 38) and a fundamental number of 64 as in the exotic pigs with XY complement in males and XX complement in female...
متن کاملImpact of cytogenetic and molecular cytogenetic studies on hematologic malignancies.
Conventional cytogenetic analysis of chromosome abnormalities in hematologic malignancies is hampered by the low mitotic index and poor quality of metaphases. A range of techniques based on fluorescence in situ hybridization (FISH) has greatly enhanced the identification of non-random translocations and deletions, pinpointing regions which contain genes involved in leukemogenesis. One of the ma...
