چکیده

In vitro radiation survival of peripheral blood T lymphocytes was studied in 1 5 clinically normal adults and 4 patients with Fanconi’s anemia. Tritiated thymidine incorporation in a whole blood lymphocyte stimulation test (1ST) and a newly developed whole blood T-lymphocyte colony assay were used to measure lymphocyte blastogenesis and colony formation in response to phytohemagglutinin (PHA) or concanavalin-A (Con-A) stimulation. Lymphocyte colony formation was found to be consistently more sensitive than the LST for detection of low-level radiation effects using both normal cells and lymphocytes from Fanconi’s anemia patients. Lymphocytes from patients with Fanconi’s anemia were significantly more

Effects of radiation on survival and recovery of T lymphocyte subsets in C3H/HeN mice.

The aims of this study were to determine the radiosensitivities of murine thymic and splenic CD4+ and CD8+ lymphocytes and to evaluate the regeneration of these cells in a model of radiation-induced hematopoietic and immune suppression. CD4+ and CD8+ cells were quantitated using two-color flow-cytometric analysis. Cells obtained from C3H/HeN mice 24 hours after exposure to 0.25-8.0 Gy (0.4 Gy/m...

Fanconi Anemia Concurrent with an Unusual Thumb Polydactyly: A Case Report

  This case report presents a case of Fanconi’s Anemia with an unusual thumb polydactyly in a 2-year old boy. The extra thumb had no nail, nail bed and distal phalanx. The extra thumb had no active motion.The duplication of the thumb occurred at the carpometacarpal joint but its morphology did not match with any classification described for thumb polydactyly. Although his thumb polydactyly was ...
