After irradiation, the mice were given TJ-48 (1.25 g in 100 ml drinking water). Study of the mechanism of Corynebacterium parvum ... We report here for the first time that stable chimerism achieved in NOD mice using a sublethal radiation-based conditioning approach is sufficient to prevent beta-cell destruction and abrogate insulitis in prediabetic NOD mice. Mice were divided into the irradiated WT mice (n=16) and irradiated SRC-3 −/− mice (n=16). 46, No. At 4 and 12 h following irradiation, there was a modest 1.5 fold (p = 0.0530) and twofold (p = 0.0309) reduction in the number of γ-H2AX positive foci in CBCs of FLASH irradiated mice compared to . Differential Recovery of Antibody Production Potential ... The enhancement of committed hematopoietic stem cell ... Irradiated control mice received only propylene glycol. After the lapse of 18 to 25 days all mice, including control batches which had received irradiation but not . the blood cell content in mice of different strains after irradiation revealed most pronounced differences in the of stab and segmented neutrophils and lymphocytes (Fig. Bone marrow transplantation. Developmental Immunology, 1995, Vol 4, pp. In this setting, there was a mortality of 40%, although this could likely be either a result of GvHD or of the irradiation . The percentage of NOD mouse recipients (8 wk of age) that engrafted with donor bone marrow correlated with the dose of . All animals (except controls) were sub-lethally irradiated using Gamma-radiation produced by IRCM irradiator type J.L. Whole body irradiation causes premature frailty. Drug-treated mice also demonstrated increased erythropoiesis, as CFU-e/BFU-e concentrations from both marrow (9% to 581%) and spleen (15% to 797%) were elevated. Doses of 700 to 1300 cGy are myeloablative 2 (Duran-Struuck, R. and Dysko, R., 2009). SUMMARY-RF mice were irradiated with a high sublethal dose (530 rads) of X rays and treated with CS7BL spleen cells, bone marrow, or both. Adult mice [ CBA/J (H-2k) ], which received either a single sublethal dose of x-radiation (500 rad) or urethan plus 500 rad, were given intravenous injections of C3H/HeJ (H-2k) spleen or bone marrow cells (18 to 42 x 106 cells per mouse) or both, for 3 days. The observed invasive effect of sublethal irradiation in U87-Fluc cells in vivo may have clinical relevance. We examined the significance of a polyherbal medicine called "EMSA Eritin" on immunological responses in sublethally irradiated mice focusing on the involvement of Treg, naïve T cell, and also the development and differentiation of T cells in thymus. Effects of Sublethal Irradiation on Patterns of Engraftment after Murine Bone Marrow Transplantation. On days 2 and 3, the blood from two animals was culture positive, but after day 3, blood cultures were negative. The mice were randomly divided into the Control (non -irradiated mice fed a standard diet without LF), IR (irradiated mice fed a standard diet) and IR+LF (irradiated mice fed LF) groups. Total body irradiation (TBI) of mice was performed using 60 Co γ-radiation [4.5 Gy total dose; 0.934 Gy/min at room temperature (25±2°C)]. To examine whether sublethal irradiation of growing tumors improves tumor rejection by a recombinant anticancer vaccine regimen, we vaccinated mice with a diversified prime and boost regimen with CEA/TRICOM . The mice were randomly divided into the Control (non‑irradiated mice fed a standard diet without LF), IR (irradiated mice fed a standard diet) and IR+LF (irradiated mice fed LF) groups. In sublethal dose-irradiated mice, Clod-Lip reduced the survival rate, the total number of bone marrow and hematopoietic stem cells, delayed peripheral blood recovery of red blood cells and platelets. Flow cytometric analysis showed that sublethal doses of total body irradiation (TBI) significantly increased long-term (14 weeks) donor chimerism in the bone marrow compared with . As shown in Fig. CBA and C57B1 mice were exposed to LD50/30 doses of γ-radiation and at intervals after irradiation the numbers of haemopoietic colony-forming units (CFU) and of antibody-producing cells in the spleen were determined. Prophylactic effect of sublethal irradiation as a result of abrogation of suppressor T cell generation in mice genetically susceptible to leishmania tropica . Specifically, irradiation and treatment with CsA in NSG mice was previously reported in a xenogeneic model, where human PBMCs were injected between sublethal irradiation and intraperitoneal administration of CsA [22, 23]. Indeed, sublethal irradiation can increase Fas expression on tumor cells , potentially rendering insulinomas in dual-conditioned mice more sensitive to Fas-mediated apoptosis than tumors in αCD40-only conditioned mice. Recipients were sacrificed 3 and 7 days after bone marrow transplantation to assess total cell counts isolated from the right femur using a . In line with a protective role of Parp-2 against irradiation-induced apoptosis, loss of p53 or the pro-apoptotic BH3-only . In the absence of Parp-2, inefficient DNA damage response increases apoptosis of hematopoietic cells. The vitamin protected these cells by a factor of 1.7 when cell count per tibia was taken as the biological end point. the fact that irradiated mice treated with anti-IL-1 receptor antibodies before such irradiation manifest increased radiosensitivity (2). Radiation source: X-rays may require lower dosages than gamma irradiation.The power output of the X-ray tube and the presence of shielding may affect this. Specify mouse identity, number, dose and use of a Lucite pie. The increased rate of VEGF level was higher in the irradiated group than in the unirradiated cells and correlated with the growth rate of tumor size. (from 4 ± 1 days for not irradiated to 11 ± 1 days for locally irradiated mice . Specifically, irradiation and treatment with CsA in NSG mice was previously reported in a xenogeneic model, where human PBMCs were injected between sublethal irradiation and intraperitoneal administration of CsA [22, 23]. Doses of radiation used were consist-ently sublethal for other strains of mice. The age of the mouse is important as well, older mice being more resistant. However, it could increase the number of CMP, MEP and myeloid cells, which suggested that Clod-Lip could induce HSC to myeloid differentiation in . The enriched T cells were incubated with 2 × 10 5 splenocytes irradiated at 15 Gy from various strains of mice including donor (B6) mice, recipient (BALB/c) mice and third-party (C3 H) mice as .
