The authors studied oncologic mortality among the workers exposed to some acryl monomers. The oncologic risk was estimated for the individuals exposed to acrylonitrile, methyl methacrylate, methyl- and butyl acrylate, methacrylic acid. Occurrence of the malignancies appeared to depend on the dose of methyl methacrylate. 相似文献

Management of chronic pain is now not only medical but a very important social and economic problem. The approaches to its management in specialized pain control centers are discussed basing on the 20-year experience of the first such center in Russia: pain control clinic with therapeutic and diagnostic center "Integrative Medicine" at Research Center of Surgery. The problems of personnel for such pain control centers, cost-effect issues, diagnostic and therapeutic methods including an advanced technique, resonance electropuncture analgesia and therapy, are reviewed. 相似文献

In comparing the results of glucose tolerance tests conducted against the background of cortisone action and without it the former one proved to have advantages over the latter one in studying the incretory function of the pancreas. A biphasic character of insulin secretion in glucose loading was revealed with the aid of this test. Secretion of insulin by the pancreas was better reflected by the dynamics of insulin content in the blood of the pancreatic-duodenal vein that by the dynamics of its content in the blood of the peripheral veins. 相似文献

The effect of ketamine administered to 20 rabbits in a single dose and in fractionated doses on the blood clotting system was studied. The following blood clotting indices were determined: thrombelastography (TEG), plasma thrombin time, platelet count, euglobulin lysis time. No statistically significant differences were observed in the activity of clotting and fibrinolysis systems in the group of animals receiving a single dose of ketamine and in the group receiving fractionated doses. The obtained results suggest that ketamine as an agent used for dissociative anaesthesia can be administered safely in serious conditions associated with disturbances in the haemostasis system. 相似文献
