Variablity of chromosomal radioadaptive response in human lymphocytes.
Background : There are growing evidences for chromosomal radioadaptive response in human lymphocytes . Highly variable inter- and intra-individual responses have been reported. Some individuals are non-responders and even in some donors the frequency of chromatid aberrations induced by a challenge dose increases by pre-exposure to an adapting dose. It has been proposed that the lack of radioada...
متن کاملIMMUNOSUPPRESSION IN HUMAN UTERINE TISSUES THROUGHOUT THE REPRODUCTIVE CYCLE
The purpose of this study was to investigate and compare whether the explant supernatants prepared from endometrial tissues during the proliferative phase, secretory phase and early pregnancy differ in immunosuppressive activity. Specimens of nonpregnant endometrium from hysterectomies and normal first trimester decidua following elective aspiration termination of pregnancy were obtained. ...
متن کاملActivation of Human Lymphocytes
Lectins and other polyclonal lymphocyte stimulants have been used extensively both to analyze early events in cellular activation and clinically as aids to the assessment of immunocompetence (1-5). Earlier studies of the response of human blood lymphocytes to lectins provided suggestive evidence for heterogeneity of responding lymphocyte populations (6, 7). Chessin et al. (6) showed that the ly...
متن کاملRegulation of human gut B lymphocytes by T lymphocytes.
The aims of this study were first, to assess whether or not immunoglobulin secretion from human gut mucosal B lymphocytes can be modified by T lymphocytes, and second whether human gut mucosal T lymphocytes are capable of regulating mucosal B lymphocyte function. T and B lymphocyte enriched cell populations were isolated from gut mucosa and co-cultured in varying proportions. Addition of T lymp...
متن کاملHuman Bocavirus in Tonsillar Lymphocytes
M. setense is an emerging organism of the M. fortuitum group that must be added to the growing list of rapidly growing mycobacteria isolated from humans. The initial gram-positive rod appearance of M. setense may delay its accurate identifi cation. Determination of antimicrobial drug susceptibility needs to be conducted by the reference broth dilution method. Further reports are warranted to ch...
