Again, immune deficient mice received either no irradiation or 2.7Gy of total body irradiation before receiving 1 × 10 6 wild type bone marrow cells intravenously from luciferase transgenic mice. studied in mice subjected to sublethal X-ray irradiation.

DNA recombination of the immunoglobulin (Ig) or T cell receptor (TCR) gene loci is an essential step in the production of lymphocytes bearing antigen-specific r The experimental approach utilized sublethally irradiated mice reconstituted with either thymus cells (thyc), or bone marrow cells (bmc) at different times after irradiation. ABSTRACT 1. 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]. Mice of the C57BL strain are more resistant to irradiation damage, whereas BALB/c mice are more . C3H/HeJ tail-skin homografts were retained (over 130 days) by these mice, whereas BALB/cJ (H-2d) homografts all were rejected within 33 days. the fact that irradiated mice treated with anti-IL-1 receptor antibodies before such irradiation manifest increased radiosensitivity (2). Effects of acute sublethal gamma radiation exposure on aggressive behavior in male mice: A dose-response study CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Many studies have already examined the hematopoietic recovery after irradiation but paid with very little attention to the bone marrow microenvironment. During the generation of these mice at Jackson Labs, 3-week-old female NSG mice were irradiated at 1.4 Gy to deplete their bone marrow and injected with CD34 + human HSCs. The survival rate at 30 d after irradiation was relatively higher in the LF group than in the control group (LF-free), (85 and 62%, respectively). 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. Radiat. 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.
Bone marrow and spleen were harvested from normal and irradiated mice on days 2, 4, 7, 10, and 14 postexposure, and cytokine mRNA levels were determined by . Compared to controls, drug-treated mice showed marked peripheral blood leuko-cytosis and more stable packed red cell volume.
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 . The influence of supplemental vitamin C on the survival of nucleated bone marrow cells was examined in Swiss Webster mice following whole-body sublethal X irradiation (3.5 Gy).
rhGH protected 17 out of 28 mice . For DT-mediated Lepr + cell depletion using Lepr-Cre;iDTR mice, 250 ng of DT (Sigma) were injected i.p. Mice were given single injections of sheep erythrocytes (SE) or polyvinylpyrrolidone (PVP) at various times after sublethal, whole-body irradiation (550 rad 60CO) and direct, antigen-specific, plaqu. body irradiation at the indicated times. / Ghetie, Maria Ana; Gordon, Brian E.; Podar, Erika M.; Vitetta, Ellen S. In: Laboratory animal science, Vol. The serum VEGF concentration in the mice with tumor formation increased after injection . The effect of CsA (7.5 mg/kg body weight) on sublethally X-ray irradiated (2 Gy) and non-irradiated NSG mice was tested. For myeloablation in preparation for BMT, total whole-body irradiation (TBI) is used. Adult mice [CBA/J (H-2 k )], whicn received either a single sublethal dose of x-radiation (500 rad) or urethan plus 500 rad, were given intravenous injections of C3H/HeJ (H-2 k ) spleen or bone marrow cells (18 to 42 × 10 6 cells per mouse) or both, for 3 days. On day 7, mice were irradiated with a sublethal dose of 5 Gy gamma rays. Immediately following sublethal total-body irradiation (500 cGy), C57BL/6 mice were reconstituted with 2×10 7 unfractionated splenocytes from naive B6 mice. 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. Res. The age of the mouse is important as well, older mice being more resistant. Female C57BL/6N mice (6-8 weeks old) were irradiated at doses of 1, 2, 3, 5, or 7 Gy from a 60Co source. 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 .
However, the process of CD4 + CD8+ double positive cell reconstitution was biphasic showing two waves of regeneration between Days 7 and 14 and after . The survival rate at 30 d after irradiation was relatively higher in the LF group than in the control group (LF-free), (85 and 62%, respectively). At 12 weeks after transplant, each mouse was tested by FACS for engraftment of human CD45 + and murine CD45 + cells. For sublethal study mice, at 6 hours and day 1 PI, B. mallei was cultured from the spleens and livers of all mice and from the blood and lung from only one of four (different) animals. However, this repression did not appear until 60 days after irradiation of .
At 3 months, the tumors were harvested to analyze the microvessel density . The stimulation of macrophage . Of the shipment received Janu-ary 28th, 62 mice were exposed to 350 r two days after arrival. The observation time-points for peripheral blood counts were on days 3, 7, 11, 14, 21 and 28 following TBI. 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]. ; Age: Dosages may need to be decreased for periods of sensitivity or increased for periods of resistance during aging 5.Of note, there are large changes in radiosensitivity . The antitumour activity of C. parvum against two different tumours, a lymphosarcoma grafted in XVII mice and a mammary carcinoma grafted in C3H mice, was a radiosensitive phenomenon.
3, 1996, p. 305-309. Bone marrow transplantation (BMT) and sublethal irradiation (XRT) cause profound long-term damage to hematopoietic stem cells. A similar difference is noted for BL/6 mice, though the dose values for the BL/6 mice are greater by about 100 cGy. Only limited protec-tion was observed in vaccinated normal mice (16.7%), whereas significantly greater . Nonetheless previous studies in a murine model of reversible radio-induced bone marrow aplasia have shown a significant increase in alkaline phosphatase activity (ALP) prior to hematopoietic regeneration. We used the competitive repopulation assay in mice to test the ability o. Shepherd Mark1-68-A-1 which has a 82 TBq Cesium . Tag mice prior to irradiation (several days in advance is best). BALB/c mice were irradiated with 7.5 Gy and treated post-irradiation with rhGH intravenously at a once daily dose of 20 µg/dose for 35 days. In this study, we investigated the ability of recombinant human growth hormone (rhGH) to mitigate against radiation injury in mice and nonhuman primates. Mice were divided into the irradiated WT mice (n=16) and irradiated SRC-3 −/− mice (n=16). One mouse had to be culled due to acute radiation sickness before the first frailty assessment. CsA was administered orally every twelve hours for nine days. Administration of spleen cells produced high mortality attributable to an acute graft-versus-host reaction and myeloid tissue depletion.
