    Abstract Simultaneous measurement of tritium and (14)C would provide an added tool for tracing organic compounds through environmental systems and is possible via beta energy spectroscopy of sample-derived methane in internal-source gas proportional counters. Since the mid-1960's atmospheric tritium and (14)C have fallen dramatically as the isotopic injections from aboveground nuclear testing have been diluted into the ocean and biosphere. In this work, the feasibility of simultaneous tritium and (14)C measurements via proportional counters is revisited in light of significant changes in both the atmospheric and biosphere isotopics and the development of new ultra-low-background gas proportional counting capabilities for small samples (roughly 50 cc methane). A Geant4 Monte Carlo model of a Pacific Northwest National Laboratory (PNNL) proportional counter response to tritium and (14)C is used to analyze small samples of two different methane sources to illustrate the range of applicability of contemporary simultaneous measurements and their limitations. Because the two methane sources examined were not sample size limited, we could compare the small-sample measurements performed at PNNL with analysis of larger samples performed at a commercial laboratory. These first results show that the dual-isotope simultaneous measurement is well matched for methane samples that are atmospheric or have an elevated source of tritium (i.e. landfill gas). However, for samples with low/modern tritium isotopics (rainwater), commercial separation and counting is a better fit.

    Title translation Correction of chronic disorders of duodenal patency in the prevention of postoperative complications of peptic ulcer.
    Abstract Experiments on dogs demonstrated the role of chronic disorders of duodenal patency (ChDDP) in the development of immediate and late-term postoperative complications of gastric and duodenal ulcer, like incompetence of the duodenal stump, reflux gastritis, progression of duodenostasis existing before the operation, the afferent loop syndrome, postresection cholecystitis and pancreatitis, the dumping syndrome. The formation of valvar anastomoses and early recognition and correction fo ChDDP in resection of the stomach (554 patients) made it possible to reduce significantly both the mortality rates (0.18%) and the percentage of other complications.

    Title translation Evaluation of abdominal treatment with magnetite suspension in peritonitis.
    Abstract The work discusses the results of the effect of intraoperative treatment of the abdominal cavity with a magnetite suspension on the T-cell link of the immunological reactivity of the organism of patients with diffuse forms of peritonitis. The preparation intensified lymphocyte proliferative activity. It was found that increase of the lymphocyte stimulation index in intraoperative treatment of the abdominal cavity with magnetite suspension in peritonitis was consequent upon increased production of interleukin-1 and other growth factors by macrophages.

    Abstract The enteral probe feeding was used in 60 patients operated on organs of the abdominal cavity in planned order. The individual nutrition media were composed with special reference to metabolic disorders and the functional state of the gastro-intestinal tract. It helped to make an adequate correction of metabolic disorders and facilitated early normalization of motor activity of the gastro-intestinal tract.

    Title translation Principle of plotting the age distribution of persons with hereditary diseases at various ages of onset and differential mortality.
    Abstract A method for ascertaining the mode of current age distributions is suggested for accurate quantitative assessment of some genetic parameters of hereditary diseases, such as age-specific penetrance, frequency of heterozygotes in the general population, fitness. The method is based on estimating the age-specific proportion of affected among the total number of heterozygotes, which seems more reasonable than the common methodology, considering the age-specific proportion of affected among all cases of the disease indicated.
