[en] Sorption of heavy metal compounds from aqueous media is studied using a chemisorption fibrous material, Vion KH-1, containing carboxylic groups. The results of chromatographic and photometric analyses are indicative of a high efficiency of iron, copper, cobalt, zinc, cadmium, and lead mixture sorption from water when the concentration of each component is about 50 MPCV.

[en] Results of investigations into extraction from solutions of the most genetically dangerous long-lived isotopes - cobalt-60, cesium-134, strontium-90, on low-base anionite (sorption exchange capacity is 5.7 mg x eq/g) are presented. Sorption dependence on low-base anionie of cesium-134, cobalt-60, strontium-90 from pH of solution is studied. It is shown that in 4-8 pH range sorption achieves its maximum value (99.8%). The effect of changes of CsNO₃ microconcentration on the degree of cesium-134 extraction from solution on low-base anionite is studied. It is established that increase of CsNO₃ concentration from 10^-5 to 10^-3 g x eq/l brings about the rise in the amount of isotope absorbed by 100 g of sorbent (q) and the degree of extraction practically does not change

[en] Concentration of uranium, aurum, platimun and palladium ions in bog waters using chemisorption vion fibers is treated. Sorbents are compared, dependence of uranium sorption from exposure time and pH value of solutions is established. High chemisorption ability of vion to uranium is noted, that makes possible using the fiber for detect of industrial concentrations of mentioned elements

[en] The report discusses early-onset radiation injuries in the urinary bladder of more than 1000 patients with cancer of the cervix and corpus uteri. Clinical symptoms of such injuries were observed in 487 patients (44.3%). In 47 (10%), the lesions were pronounced. The degree of radiation-induced cystitis was evaluated on a 6-point scale used by WHO classification (1982). Said lesions mainly occurred at stage III of tumor and predominantly in cases of cancer of the corpus uteri. Complications development was stimulated by vascular lesions, diabetes mellitus and inflammatiry processes in pelvic organs. Radiation injuries were treated by standard procedures as well as with immobilised trypsin administered in a cellulose powder vehicle. this method proved the immobilised trypsin adminstered in a cellulose powder vehicle. This method proved the most effective. Since patients suffering early-onset radiation-induced destructive injuries are at high risk of further exacerbation at later stages, they should be followed-up closely

[en] At present the problem of bladder injuries and methods of their therapy are very urgent in view of a wide use of radiation therapy of cancer of the uterine body, bladder and rectum. None of the existing methods of therapy of local radiation cystitis is sufficiently effective. To obtain better therapeutic results and immobilizaed trypsin preparation on a powder like cellulose matrix was used. Therapy was provided to 34 patients with symptoms of acute radiation cytitis. The therapy in all the cases proved to be effective. It was confirmed by the disappearance of clinical symptoms and cytoscopic findings

[en] For objective palpation, visual and morphological evaluation of tumoral affection borders of patients with nonresectable tumors of pancreato-duodenal localization the radiotherapy method during palliative biliodigestive anastamozes has been used. The method of intraoperative labeling of the whole affected organ, tumoral infiltrate and regional metastatic spreading zones is described in the paper. It is stressed that application of the suggested method contributes to the choice of most optimal conditions at individual radiotherapy planning

[en] In the natural waters of mining regions, for example, Karelia, there are uranium and noble-metal ions, whose concentration amounts to 10^-8-10^-10 g/liter, which is close to or above the sensitivity threshold of methods employed for their analysis. Existing methods of concentration are laborious to carry out and require transportation of large volumes of samples and do not always guarantee detection of elements of interest. It was of interest to carry out studies using Vion chemisorptive fibers, which have high values for specific surface and static-exchange capacity. Thanks to this, a considerable shortening in duration of the process for sorbing the elements and a more complete trapping of these from low-concentration solutions was expected. As chemisorbents the authors used the fibrous materials Vion KN-1 (in the Na-form), AN-1, and AN-3, which are characterized by static-exchange capacities of 5.3; 2.3; and 2.7 meq/g, respectively. Investigations of the sorption of uranium and of noble metals by the indicated chemisorbents was carried out under laboratory and field conditions

[en] 139 patients with stomach and esophagus cancer have been studied to shoW the adVisability of a combined treatment including preoperative irradiation and the following operation. Radiotherapy has been carried out on a betatron with the 25 MeV boundary generation energy. Everyday single doses have been 180-250 rad. The integral focal dose on the tumor and zones of regional metastasis have become 3000-4500 rad within 3-4 weeks. It is established that a combined treatment of patients with stomach and esophagus cancer permits to improve the immediate results of treatment
