The purpose of the study was to compare the results of using decellularized human amniotic membrane isolated and together with lyophilisates of conditioned media of MSCs from the human gingival mucosa and MSCs from human placental tissue and their effect on tissue regeneration in LRI. Material and methods: The study included 42 laboratory animals (white male rats of the Wistar line), randomly divided into 6 groups: K – control group without therapy, on the 21st day after irradiation, groups using: Am+LD – application of lyophilisate of the conditioned medium of MSCs of the human gingival mucosa (LD) under the decellularized amniotic membrane, Am+LP – application of lyophilisate of the conditioned medium of MSCs of human placental tissue (LP) under the decellularized amniotic membrane, Am – application of the decellularized amniotic membrane, AmCl – application of the decellularized amniotic membrane with medical glue BF-6, Kl – application medical glue BF-6. Modeling of LRI in animals was carried out on an LNK-268 X-ray unit at a dose of 110 Gy and observed until the 112th day after irradiation, monitoring of the ulcerative surface of the skin and the course of the inflammatory process of LRI was carried out with calculation of the area of ​​the total changed skin in the ImageTool software. Planimetric and histological analyzes were performed. Results: It was demonstrated that, when compared with the control, the use of decellularized amniotic membrane in LRI on days 77 and 112 after irradiation increased the healing rate by 4.6 and 18 times, respectively; decellularized amniotic membrane with lyophilisate of placental MSC conditioned medium increased the rate of wound healing by 13.5 and 27 times, respectively; and a dellularized amniotic membrane with lyophilisate of MSCs from the human gingival mucosa to 100 % healing. Healing of the ulcer surface area of the LRI in 83.5 % of animals in the Am group demonstrated the effectiveness of using isolated decellularized amniotic membrane even in the absence of human MSC lyophilisates. At the same time, healing of the ulcer surface area of the LRI in the AmCl group was 20 % of cases, where the decellularized amniotic membrane was fixed with BF-6 medical glue, which was less effective compared to other groups. Conclusion: The proposed combined use of decellularized amniotic membrane with lyophilisates of the conditioned medium of mesenchymal stromal cells (MSCs) of the placenta and mucous tissue of the human gums and the isolated use of decellularized amniotic membrane led to complete epithelization of the ulcer surface, a pronounced favorable course of grade IIIb–IV LRI in laboratory animals and a reduction in healing time , the absence of local or systemic complications can be considered as a promising method of conservative treatmen","PeriodicalId":37358,"journal":{"name":"Medical Radiology and Radiation Safety","volume":"94 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141408634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A sufficient number of works are devoted to the radioprotective properties of ribonucleoside riboxin (inosine). However, studies comparing the direct radioprotective properties of riboxin and a recognized radioprotector, for example, indralin, using a survival test in irradiated animals have not yet been carried out. Purpose: Conduct a comparative assessment of the radioprotective properties of riboxin and indralin using a survival test in mice exposed to external X-ray radiation. Material and methods: The experiment was carried out on 200 male ICR (CD-1) mice of the SPF category in duplicate. In each experiment, the animals were divided into the following groups, separated by body weight, 10 animals each: vivar control, not exposed to drugs and radiation, radiation control, with preliminary intraperitoneal administration of sterile water and exposed to external X-ray radiation in doses of 6.0, 6.5 and 6.75 Gy, experimental groups exposed to irradiation in the indicated doses with preliminary intraperitoneal administration of riboxin at a dosage of 100 ml/kg body weight or indralin at a dosage of 100 ml/kg. Survival was assessed for 30 days after irradiation. The dose change factor was determined using probit analysis as the ratio of the radiation dose causing the death of half of the irradiated animals that received the drug to the radiation dose causing the death of half of the irradiated animals without administration of the drug. Results: The use of indralin before X-ray irradiation in doses of 6.0 Gy, 6.5 Gy and 6.75 Gy led to a statistically significant increase in the survival of animals compared to the group receiving Riboxin and control irradiation (р<0,05, log-rank test). Using equations derived from Phinney probit analysis, LD50 doses were calculated for indralin and riboxin, from which dose change factors were calculated to be 1.8 and 1.07, respectively. Conclusion: Since riboxin has not demonstrated radioprotective properties, its preventive use with intraperitoneal administration under the conditions described in this paper, for leveling the effects of radiation can be considered ineffective.","PeriodicalId":37358,"journal":{"name":"Medical Radiology and Radiation Safety","volume":"88 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140778237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the successful establishment of nuclear physics medical elementology as a new scientific discipline, it is necessary to develop a clear methodology for its further development. Results: The definition of the subject of research and the main postulates of medical elementology is given. The close interrelation of knowledge about the content and metabolism of chemical elements, as well as their radioactive and stable isotopes, with the needs of medical radiology is shown. The following areas of research are considered: 1) The use of chemical elements, as well as their radioactive and stable isotopes in medicine; 2) Visualization of organs and tissues, as well as in vivo determination of the content of chemical elements in them; 3) Nuclear physical methods for determining chemical elements in samples of tissues and fluids of the human body in solving oncological problems; 4) The role of chemical elements in calculating absorbed doses during radiotherapy; 5) The use of nuclear physical methods in the formation of groups at increased risk of cancer. A range of modern nuclear physics analytical methods acceptable in clinical practice and as an adequate research tool is outlined. The need for the integrated use of nuclear physics analytical technologies to obtain reference values ​​for the content of chemical elements in various organs, tissues and fluids of the human body in normal and various pathological conditions, as well as to organize the strictest quality control of measurements and unify methodological approaches is demonstrated. The modern possibilities of using the achievements of nuclear physics medical elementology in solving the problems of medical radiology are determined and the priorities for the future are outlined.

The sample included 30 papers and covered cohorts from 6 countries plus an NW cohort from 15 countries. For the sample, in most cases based on published standardized mortality rates (SMR), the relative risks (RR) of mortality from CVD were calculated for the selected dose groups with subsequent processing of the material for outliers. Initial: n = 207; final sample: n = 199; covers very low (0–10 mSv; 15.8 % of the sample), low (>10–100 mSv; 45.8 %) and moderate (>100–1000 mSv; 36.4 %) doses; data for high doses (>1000 mSv; n = 4; 2 % of the sample), due to dubiousness, were excluded. A systematic review and pooled analysis of the RR for mortality from CVD depending on the dose on an ordinal scale was performed on the final sample. For the entire dose range (0–1000 mSv) and for moderate doses, statistically significant trends in increasing RR were found when expressed in five types of regressions (except for the logarithmic one for the entire range). Although the r values were small (0.230–0.293), the effect was clear. The ERR per 1 Gy (Sv) calculated for moderate doses using linear regression was 0.54. This value is higher than those obtained previously in meta-analyses, but should be considered as the most adequate. No dose relationship was found for the very low + low dose range (0–100 mGy); the r coefficients for the regressions were either negligible or negative at statistical insignificance. For the subthreshold dose range for CVD mortality after exposure (according to UNSCEAR and ICRP: 500 mSv), only a weak trend towards an increase in RR was found, statistically insignificant, despite the large sample size (n = 191), while for the dose range 500–1000 mSv, the highest tendency among the pooled analyzes was revealed to increase the risk depending on the level of exposure (r = 0.297–0.423; statistically insignificant due to the small sample size: n = 8). It is concluded that for mortality from CVD after irradiation, the threshold value of 0.5 Gy established by UNSCEAR and ICRP and confirmed in the present pooled analysis should be strictly adhered to. Due to the lack of effects of low doses, it is inappropriate to raise the issue of low dose effects in the context of these pathologies.","PeriodicalId":37358,"journal":{"name":"Medical Radiology and Radiation Safety","volume":"223 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140793770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
