Nevertheless, we were able to rescue less than half of the mice from the radiation exposure in that model (40% survival). Comparison of hBMSC-Luc/GFP persistence in the femurs of mice with and without 2 Gy sub-lethal irradiation prior to transplant. Al filtration, maximum output 470 . Presented at the Thirty-ninth Annual Meeting of the Radiological Society of North . The investigators inactivated Listeria with lethal doses of gamma radiation and then vaccinated a group of 10 mice twice with the irradiated bacteria. Authors John S Thompson 1 , Yanxia Chu, Judith Glass, Andrea A Tapp, Stephen A Brown. Lethally irradiated mice, which otherwise die from complete hematopoietic failure, can be rescued with as few as 20 selected stem cells. Thus, even a full day after irradiation, the joint lethal effect was as great as when no time had been allowed for recovery. 2010 May;44(5):529-40. doi: 10.3109/10715761003649578. Countermeasures against radiation are critically needed. Determinations of the number of nucleated cells present in bone-marrow and spleen showed a continuous increase in lethally-irradiated mice treated with syngeneic cells and in supralethally-irradiated mice treated with allogeneic cells. In mice irradiated at a dose of 1 Gy, mtDNA copy number in nucleated blood cells was reduced by 50% within 1 h post-irradiation and was not restored during a 3-day period of observation.
Biol., Vol. of irradiation leading to 50 % lethality at 30 days in 8 week old BALB/C mice is 50 cGy less than that for 3 month old mice of the same strain. INTRODUCTION. The manganese superoxide dismutase mimetic, M40403, protects adult mice from lethal total body irradiation @article{Thompson2010TheMS, title={The manganese superoxide dismutase mimetic, M40403, protects adult mice from lethal total body irradiation}, author={John S. Thompson and Y. Chu and J. Genetically marked mesenchymal stem cells, found in bone marrow, will "in sublethally irradiated animals . The irradiation procedure, itself, is painless. Int.
Twenty-eight days after the first vaccinations, all the mice were . In lethally-irradiated mice treated with allogeneic bone- An interval of 1 h between the the irradiated group of animals (Fig.
irradiation only 15% of 40 mice survived. One donor strain 2. In this paper there will be presented pertinent data on mice, collected during the years 1949-53. After lethal irradiation long-lived, immunologically vigorous C3Hf mice were produced by treatment with syngeneic fetal liver cells or syngeneic newborn or adult spleen cells.
The tumor volume of mice treated with metformin plus X-irradiation was significantly smaller than that of mice treated with X-irradiation alone (Figures 7A and 7B).
Moreover, the days required for 2-fold increase of tumor volume in mice treated with X-irradiation alone and metformin plus X-irradiation were 18 (13-22) and 25 (21-29) days . In experiments with chemical mutagens, 101/Hf strain was most
Irradiation . RAD SOURCE Technolgies RS2000 is an excellent device to accomplish this.
Depletion of T cells in donor bone marrow. More than 80% of the transgenic mice survive long term (more than 3 months) when subjected to a routine lethal preconditioning regimen for bone marrow or stem cell transplantation, fractionated irradiation of 9.5 Gy (two doses of 4.75 Gy, 3 hours apart; Fig 3B).
2b,c). To assess the effects of MSCs on survival after lethal irradiation, we infused syngeneic MSCs (either as immortalized MSCs clones or primary MSCs) intravenously into wild-type C57/Bl6 mice within 24 hours of lethal total body irradiation (TBI).
Dose reduction factor (DRF) for REC-2001 was also analyzed in mice to observe its potential against supra lethal radiation. Genetics. 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 use of DietGel76A™ has significantly improved the recovery of C57BL/6 mice after sub-lethal irradiation.
The maximum tol.
BALB/c mice were irradiated with 7.5 Gy and treated post-irradiation with rhGH intravenously at a once daily dose of 20 microg/dose for 35 days.
Lethal Irradiation of Mice with High Doses of Roentgen and Gamma Rays 1 P. Bonét-Maury and F. Patti Paris , France ↵ 1 From the Institut du Radium, Paris. 3. A similar difference is noted for BL/6 mice, though the dose values for the BL/6 mice are greater by about 100 cGy. tance to lethal irradiation, to I1:1- and TNF-induced recovery from lethal irradiation, to induction of ACTH 1 by I1:1, and to TNF-induced hypoglycemia. After lethal irradiation long-lived, immunologically vigorous C3Hf mice were produced by treatment with syngeneic fetal liver cells or syngeneic newborn or adult spleen cells.
Exposure to high lethal dose of ionizing radiation results in acute radiation syndrome with deleterious systemic effects to different organs. J. Radiat.
lethal irradiation of the recipients. Sub-lethal irradiation significantly increased donor chimerism in the bone marrow compared to non-irradiated recipients (69±5% compared to 6±3% in mice transplanted with 1×10 6 donor cells, p<0.05) 14 weeks after BMT (Figure 1A). 42 If given higher doses, BALB/c mice develop considerable radiation-induced sickness (lethargy, inappetance, diarrhea) that may lead to death.
These animals reconstitute the multiple lineages of hematopoiesis as predicted by the stem cell model.
Genetics. C3H/Sn mice are also considered radioresistant[1].
Male C57Bl/6 mice received recombinant adenovirus expressing human R-spondin1 (AdRspo1) or E.coli Lacz (AdLacz), 1-3 days before whole body irradiation (WBI) or abdominal irradiation (AIR).
RIGS was assessed by histological . Mice needed for bone marrow chimera: Recipient mice.
Compared with Tlr3 +/+ BMT mice, both diarrhea symptoms and body weight loss were significantly milder in Tlr3 −/− BMT mice (Fig. Acute lethal toxicity was observed following the administration of either 10 μg anti-CD40 MoAb (FGK45) or 0.5 μg of recombinant murine (rm)IL-12 that resulted in 100% mortality of all mice within 4 to 6 days. Affiliation 1 The Veterans . The same treatment had only limited benefits in the other two strains of mice used (CD45.1 and NRG) for the experiment, since no statistically significant difference was shown for body weight of Cd45.1 and NRG groups. C57BL/6 Thy1.1 mice were whole-body exposed to 9.5 Gy and injected with . We now report that suppression of CD47 using an antisense morpholino increases survival of mice exposed to lethal total body irradiation. 86, No.
10. Furazolidone Increases Survival of Mice Exposed to Lethal Total Body Irradiation through the Antiapoptosis and Antiautophagy Mechanism Shumei Ma,1 Zhao Jin,2 Yi Liu,1 Lin Liu,1 Hao Feng,1 Ping Li,1 Zhujun Tian,1 Minghua Ren ,3 and Xiaodong Liu 1,4 1School of Public Health and Management, Wenzhou Medical University, Wenzhou, Zhejiang 325035, China Mice receiving either of the MSC preparations had significantly improved survival when compared to . In the current study C3H/HeN mice were total body irradiated by 7.7 Gy. Whereas TBI was lethal for Tlr3 +/+ BMT mice, all Tlr3 −/− BMT mice survived at the same dose (Fig. Another group of 10 mice received two inoculations with heat-killed Listeria, while a third group of 10 received no vaccine. Genetic Variation in the Acute Lethal Response of Four Inbred Mouse Strains to Whole Body X-Irradiation. In previous studies completed in our laboratory, 2Gy conditioning of NSG mice was sufficient to facilitate human CD45 engraft-ment rates as high as 95% within the bone marrow cav-ities of femurs that had been directly injected with human HSPC 8 weeks . 2 The factors were as follows: 200 kv., 10 ma., 1.0 mm. FZD administration significantly improved the survival time of irradiated mice; moreover, higher FZD treatment showed better effect (Figure 1(c)). rhGH protected 17 out of 28 mice (60.7%) from lethal irradiation while only 3 out of 28 mice (10.7%) survived in the saline control group. , D. W. van Bekkum, and Shoshan Knaan The major limitation in bone marrow grafting is the occurrence of delayed secondary disease. The cumulative irradiation dose 5 mm below the active iodine-125 seeds was 23.0 Gy after 13 weeks (BEDtumor = 30.6 Gy). The hematological analyses showed that the numbers of almost all of hematopoietic cells in the surviving mice treated with effective medications recovered to the levels of non-irradiated mice. Glass and Andrea A. Tapp and Stephen P. A. Figure 4 Effects of PFTα in Balb/c and C57BL6 mice treated with whole-body gamma irradiation (results of representative experiments are shown). BALB/c mice were irradiated with 7.5 Gy and treated post-irradiation with rhGH intravenously at a once daily dose of 20 mg/dose for 35 days. Reproducibility of the Lethal Effect of Total-Body Irradiation in Mice 1 Friedrich Ellinger , M.D.
Lethal irradiation of C57/B6 mice: 950-1050 Rads administered in a split dose (3 hrs.
Normal mice handled frequently every day will have 10 to 15% variation, usually a loss, in weight. Hematopoietic reconstitution after lethal irradiation and bone marrow transplantation : Effects of .
Mice of each group were injected with different hematopoietic cytokines for 5 consecutive days starting immediately after irradiation or left uninjected. In the case of BMR, transplanted mice undergo a 5-10 day irradiation sickness period from which they generally recover within 14 days (Duran-Struuck, R and Dysko, R., 2009). With longer intervals survival increased steadily, 9 of 10 mice surviving when the treatments were separated by 5 days and all surviving when the interval was 7 days.
administration of REC-2001 and irradiation was found An estimation of DRF on the basis of whole body to be optimal for all of the doses of REC-2001 used in survival studies against supra-lethal dose (13 Gy) gave the present study (data not shown).
An impairment of the survival of mice subjected to whole-body gamma-irradiation with a lethal dose of 10 Gy and treated with a repeated postirradiation administration of prostaglandin synthesis inhibitors (PGSls), indomcthacin or diclofenac, was observed. rhGH protected 17 out of 28 mice (60.7%) from lethal irradiation while only 3 out of 28 mice (10.7%) survived in the saline control group. Grahn D. Acute Radiation Response of Mice from a Cross between Radiosensitive and Radioresistant Strains.
At a TBI of 9.0 Gy . Donor mice. 1. 10, October 2010, pp. sensitive and 129/J mice were most resistant to the lethal effects of irradiation.C57Bl mice are most frequently used for radiobiological research and are considered resistant. The rate of induced recessive lethals was estimated 1) by comparison of embryos survival between the irradiated and control groups in mating of the F1 males with their daughters, and 2) by . 1957 May;42(3):189-98. The mice were whole-body irradiated at a dose rate of 0.41 Gy/min using a γ-ray source (60 Co, Chisostat, Chirana, Prague, Czech Republic). Treatment of lethally irradiated mice with syngeneic or allogeneic newborn thymus cells or allogeneic newborn or adult splee …
Prophylactic intraperitoneal administration of citriphos (cysteamine adenosinetriphosphate) to male mice in a dose of 700, 500, and 300 mg/kg 15 min before irradiation of the animals with x rays in a dose of 700 R resulted in survival of 79, 90, and 95% of the animals, respectively, until the 30th day after irradiation, whereas none of the control animals survived until the 3Oth day. Depending upon radiation dose, they may lose as much as 25% of their body weight by day seven, but if successfully reconstituted will regain most of this weight during . Experimental Procedure: White mice of a heterogeneous population obtained by cross-breeding several strains were divided into groups of 10 animals each and were irradiated over a wide dosage range, under identical conditions, with a D.E.W. PFTα did not protect p53-null mice from lethal irradiation, which confirms that it acts through a p53-dependent mechanism in vivo . Two or even three different donor strains. irradiated mice.
