Download or read book Mechanism of Action of Radiation Protective Agents In Vivo Distribution and Metabolism of Cysteamine S Phosphate MEAP written by Bernard Shapiro and published by . This book was released on 1969 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: The appearance of a new class of protective agents, the aminoalkyl-thio-phosphates (or aminoalkyl-phosphorothioates), provided the opportunity to re-evaluate these proposed mechanisms of action. The new compounds are less toxic than the aminoalkylthiols and provide equal or better protection. A study of the distribution and metabolism of one of these agents, aminoethylthiophosphate or cysteamine-S-phosphate (MEAP) was undertaken to test the hypotheses arrived at in the mechanism studies of mercaptoethylguanidine and bis(2-guanidoethyl) disulfide. In this study, the protective agent MEAP labelled with P-32 and S-35 was analyzed in pure solutions, in homogenates of mouse tissues in vitro and in homogenates of tissues from mice given protective doses of MEAP in vivo. A small radiation mortality study was run concurrently with the distribution and metabolism studies in order to be sure that the analyzed mice were really being studied under conditions of protection. Keywords: Radiation dosage, Protective agents, Organic compounds, Toxicity, U/A Reports. (JG).

Each chapter concludes with a "summary of pertinent conclusions" to facilitate quick review and help readers retain important information.
Download or read book The Distribution and Metabolism of the Radiation Protective Agent Aminopropylaminoethyl Phosphorothioate WR 2721 in Mice written by George Kollmann and published by . This book was released on 1978 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aminopropylaminoethyl-phosphorothioate (WR-2721) is the least toxic and most effective of the phosphorothioate class of radiation protective agents. In order to investigate the mechanism of action of this agent, distribution and metabolism studies were carried out using 35S-labelled WR-2721. In mice given WR-2721 intraperitoneally, tissue analysis showed only the unchanged compound and the protective agent bound to proteins by mixed disulfide bond. Concentration of the latter form correlated best with the time course of protection. Dephosphorylation to yield the thiol form of WR-2721, necessary for mixed disulfide formation on tissue proteins, was best demonstrated in the kidneys, both in vivo and in vitro, but also occurs in other tissues. Preliminary studies with the disulfide and thiol forms of WR-2721, which are less protective and more toxic than the phosphorothioate, suggest that the presence of the phosphate is necessary to mask the sulfhydryl group during transport to the target site. Formation of a mixed disulfide with tissue protein sulfhydryl groups at the target site appears to yield the final necessary condition for radiation protection. (Author).
Download or read book Radiation in Medicine written by Institute of Medicine and published by National Academies Press. This book was released on 1996-03-25 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: Does radiation medicine need more regulation or simply better-coordinated regulation? This book addresses this and other questions of critical importance to public health and safety. The issues involved are high on the nation's agenda: the impact of radiation on public safety, the balance between federal and state authority, and the cost-benefit ratio of regulation. Although incidents of misadministration are rare, a case in Pennsylvania resulting in the death of a patient and the inadvertent exposure of others to a high dose of radiation drew attention to issues concerning the regulation of ionizing radiation in medicine and the need to examine current regulatory practices. Written at the request from the Nuclear Regulatory Commission (NRC), Radiation in Medicine reviews the regulation of ionizing radiation in medicine, focusing on the NRC's Medical Use Program, which governs the use of reactor-generated byproduct materials. The committee recommends immediate action on enforcement and provides longer term proposals for reform of the regulatory system. The volume covers: Sources of radiation and their use in medicine. Levels of risk to patients, workers, and the public. Current roles of the Nuclear Regulatory Commission, other federal agencies, and states. Criticisms from the regulated community. The committee explores alternative regulatory structures for radiation medicine and explains the rationale for the option it recommends in this volume. Based on extensive research, input from the regulated community, and the collaborative efforts of experts from a range of disciplines, Radiation in Medicine will be an important resource for federal and state policymakers and regulators, health professionals involved in radiation treatment, developers and producers of radiation equipment, insurance providers, and concerned laypersons.

Download or read book Evaluation of Guidelines for Exposures to Technologically Enhanced Naturally Occurring Radioactive Materials written by National Research Council and published by National Academies Press. This book was released on 1999-02-25 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: Naturally occurring radionuclides are found throughout the earth's crust, and they form part of the natural background of radiation to which all humans are exposed. Many human activities-such as mining and milling of ores, extraction of petroleum products, use of groundwater for domestic purposes, and living in houses-alter the natural background of radiation either by moving naturally occurring radionuclides from inaccessible locations to locations where humans are present or by concentrating the radionuclides in the exposure environment. Such alterations of the natural environment can increase, sometimes substantially, radiation exposures of the public. Exposures of the public to naturally occurring radioactive materials (NORM) that result from human activities that alter the natural environment can be subjected to regulatory control, at least to some degree. The regulation of public exposures to such technologically enhanced naturally occurring radioactive materials (TENORM) by the US Environmental Protection Agency (EPA) and other regulatory and advisory organizations is the subject of this study by the National Research Council's Committee on the Evaluation of EPA Guidelines for Exposures to Naturally Occurring Radioactive Materials.
