The goal of the paper is to assess changes in the regional differentiation of life expectancy in Russia for 2003–2017, to consider the features of the level and growth rate of life expectancy, gender differences in the indicator, the difference between urban and rural areas, the structure of mortality due to death, the level of infant mortality in the regions of Russia; the paper also defines regional reserves for further increase in life expectancy. The relevance of the topic is due to significant regional differentiation, Russia’s significant lagging behind developed countries, and the goals associated with this field. We arrange Russian regions into nine groups with annual intervals of the indicator and evaluate the changes in the groups in 2003–2017. We find out that in the conditions of growing life expectancy there has been a marked convergence of regions; they approached the Russian average level according to this indicator. Regional convergence has occurred at the expense of the extreme groups in terms of the indicator, and primarily due to the lagging regions getting closer to the leaders; i.e. we observe the catch-up nature of convergence. This suggests that over the period of 2004–2017, the relatively easy-to-implement life expectancy growth reserves, which are typical for low-indicator regions, have been used quite well, while further growth in high-indicator regions is not an easy task, since the possibilities of first-order factors, such as gender differentiation, the difference between urban and rural indicators, the share of mortality from external causes, and infant mortality rate, have been largely implemented. Nevertheless, all nine groups of regions still have reserves to increase life expectancy, due to certain growth factors of the first order. The groups with the most unfavorable level of the indicator have the greatest reserves. However, factors such as the lag in the rural indicator and the value of infant mortality in the group with very high life expectancy provide opportunities for further increase due to growth factors of the first order

The paper presents findings of a research, the goal of which was to evaluate the effectiveness of state measures aimed to promote the birth rate in Russia and its northern regions, their impact on the increase of birth rate intensity in 2007–2015. The relevance of choosing these territories for the study is determined by the high migration outflow of the population of reproductive age in most regions of the North, aggravating the growing adverse effects that the changes in the age structure have on fertility, the changes are due to the country’s demographic history. Scientific novelty of the study consists in the fact that it determines the total demographic effect of current measures of pro-family policy, evaluates the results of enhancing its activities and makes a contribution to scientific studies on identifying the impact of the behavioral component of fertility on the formation of the final number of children in the family in terms of government incentives provided to families. This goal was achieved with the use of the method of standardization by age-specific birth rates for 2006. The authors have found out that in all of the territories the intensity of the birth rate increased most significantly in the women of middle and older reproductive age, but there exist regional specifics and differences in the nature of the transformation of the age-specific birth rate pattern. A 1.3-fold increase in the total fertility rate that was planned to coincide with the second phase of action of the Demographic Policy Concept of the Russian Federation until 2025 has reached the target indicators before the deadline nationwide and in the majority of Russia’s northern regions. In the conditions of implementation of the demographic policy the number of births in Russia’s northern regions was bigger by 195.6 thousand people or 18.8% compared to the number that would have been observed if the intensity of birth rate remained at the level of 2006. The article makes an attempt to substantiate the differences in the increase in the birth rate intensity in the context of Russia’s northern regions. In the period from 2010 to 2015, when there was a growing negative impact of the age structure factor on the one hand, and the intensification of demographic policy measures on the other, an increase could be observed in the contribution of a behavioral component to the formation of the resulting birth rate. The increase in birth rate intensity is associated with the fact that families with children are in need of improving their living conditions, the subjective assessment of these conditions as poor is the factor constraining the number of births in societies where small families prevail

The study aims to analyze the impact of different types of national cultures on the effectiveness of anti-corruption measures implemented by the states, expressed in the change in the Corruption Perceptions Index for the period from 2016 to 2020. The methodological basis was such scientific methods as dialectical, logical, prognostic, and systems analysis. The methods of statistics were also used to achieve the research objectives. The study attempts to analyze the relationship between the cultural area of the country and its place in the international rating, compiled annually based on the results of the research conducted by the international organization Transparency International. The result of the study was the conclusion regarding the predominance of the countries of the Western European cultural area in the leaders of the rating as the countries with the lowest corruption perceptions index, the countries of the African cultural area as the countries predominating in the composition of the states with the highest corruption perceptions index and proportional representation of the countries of the Eastern European, South Asian and Latin American cultural area in the median values of the rating. The novelty of the work lies in the division of the countries existing in the modern world into eight cultural areas based on the value attitudes, traditions, and beliefs formed in them, which enabled to analyze the representation of countries of a particular area in a certain group of ratings – the countries with a low corruption perceptions index, the countries – with a high corruption perceptions index and the countries, in the corresponding analyzed period, occupying the median position in the rating.

The task of creating a single supranational payment market is to ensure its maximum independence, which correlates with the tasks of the competitive leading economic development of countries - the transition to a digital technological structure. To increase the efficiency of the generation of payment innovations with their subsequent diffusion into the agricultural sector, to strengthen the economy’s resistance to risks, a transfer of innovative institutional, organizational and informational forms of activity is necessary. The strategy of integration of payment markets of interstate economic associations in time and space should be based on the consolidation and symbiosis of innovative technology platforms of sovereign payment systems of the participating countries. For this, a conceptual model of a supranational transfer of digital innovations to the agricultural sector through the transmission mechanisms of payment systems is proposed. The model characterizes the mega-economic system, which provides for the heterarchical and hierarchical interaction of payment systems of donor countries and recipient countries in the framework of economic associations, in which the transfer of forms of innovative development to the agricultural sector is carried out. Digital innovations are transferred to the subjects of the agricultural market horizontally and vertically. The transfer of digital innovation occurs through institutional, organizational and informational communications with the parallel creation of structures for the subsequent evolution of the model.

Based on the unsaturated derivatives of polyfluoroalkanols chemical products are used to protect solid and fibrous materials surface from the effects of water, oils and other pollutants. A method for obtaining allyl ethers of polyfluoroalkanols (polyfluoroalkoxypropenes) is based on the Williamson ether reaction. This method is a heterophase process. The use of solvents to improve mass transfer requires complementary measures to ensure industrial and environmental safety. It is more preferable to obtain the target ethers in water with PTC. A series of experiments using different chain length polyfluoroalkanols was studied by GLC. Kovats retention indexes of the target ethers were determined. It was found that in the case of lower homologues (CF3CH2OH, (CF3)2CHOH, HCF2CF2CH2OH), the addition of 5-15 vol.% 1,4-dioxane as a solubilizer provides a high yield of products. The application of PTC (tetrabutylammonium bromide) is indispensable for using polyfluoroalkanols with a longer carbon chain (C≥5). PTC invariably provides the almost complete conversion of polyfluoroalkanols. The decomposition process of TBAB becomes noticeable (GLC method) upon completion of the main reaction. Polyfluoroalkoxypropenes form azeotrope with water, which can be used in the work up process.

Efficiently transmitting data in wireless networks requires joint optimization of routing, scheduling, and power control. As opposed to the universal dual decomposition we present a method that solves this optimization problem by fully exploiting our knowledge of active constraints. The method still maintains main requirements such as optimality, distributed implementation, multiple path routing and per-hop error performance. To reduce the complexity of the whole problem, we separate scheduling from routing and power control, including it instead in the constraint set of the joint optimization problem. Apart from the mathematical framework we introduce a routing and power control decomposition algorithm that uses the active constraint method, and we give further details on its distributed application. For verification, we apply the distributed RPCD algorithm to examples of wireless mesh backhaul networks with fixed nodes. Impressive convergence results indicate that the distributed RPCD algorithm calculates the optimum solution in one decomposition step only.

The use of pulmonary rehabilitation reduces symptoms, improves life quality and exercise tolerance. The article presents indications for physical training, their characteristics and assessment of their effectiveness in the rehabilitation of patients with chronic lung diseases. It was noted that the execution of exercise tests (a monitoring with a progressive load increase on a bicycle ergometer or treadmill, a test with a constant load, a 6-minute walk test, a shuttle test with an increasing load and a shuttle test with a constant load) is appropriate for physical training before rehabilitation course. Physical endurance training programs are an essential component of pulmonary rehabilitation. Strength training, flexibility training and upper limb exercises give a good additional effect. To assess the effectiveness after rehabilitation programs, it is advisable to perform tests with physical activity. To assess the effectiveness of rehabilitation, the constant load exercise test and the constant load shuttle test are more sensitive to changes than the increasing load tests.

The ECG stress test allows to determine possible presence of obstructive coronary atherosclerosis. The more severe the atherosclerotic lesion of coronary arteries the more likely a ST segment depression during the stress test. The article provides a description of a negative result of a stress test in a patient with multivessel coronary disease.

A growing body of data demonstrates that exercise capacity is a potentially stronger predictor of mortality than established risk factors such as smoking, hypertension, obesity, high cholesterol, and type 2 diabetes mellitus. Individuals who maintain a regular program of PA that is longer in duration, of greater intensity, or both are likely to derive greater benefit than those who engage in lesser amounts. In this review, the authors have shown the possibility of assessing physical activity and the main provisions of the appointment of physical training to improve and preserve the cardiorespiratory fitness.

The present work was aimed at studying the state of the inferior vena cava system according to the findings of duplex scanning in dynamics of acute cerebral circulation impairments (ACCI). Amongst 100 patients with ACCI, lower limb vein deep thrombosis (LLVDT) was revealed in 57% of cases. The incidence of LLVDT in patients with intracerebral haemorrhage was higher than in those with ischaemic stroke, however there were no statistically significant differences between the type of ACCI (p=0.06) and subtypes of ischaemic stroke (atherothrombotic, ceardioembolic) (p = 0.68). The main risk factors for LLVDT are the presence of pronounced motion deficit in the extremities, induced by the underlying disease (p=0.02) and immobilization. In the overwhelming majority of patients (81%) thrombosis localized isolatedly in the crural veins. Ascending thrombosis and the development of a floating thrombus were represented mainly on the side of motility deficit in the extremities. We have confirmed a strong association between positive dynamics in the neurological status of patients and frequency of recanalization of thrombi (p=0.043). Ultrasonographic examination of lower limb veins in dynamics of ACCI is an important component of preventive and therapeutic process.

Here we report on novel quantitative approaches for protein structural characterization using deep UV resonance Raman (DUVRR) spectroscopy. Specifically, we propose a new method combining hydrogen-deuterium (HD) exchange and Bayesian source separation for extracting the DUVRR signatures of various structural elements of aggregated proteins including the cross-beta core and unordered parts of amyloid fibrils. The proposed method is demonstrated using the set of DUVRR spectra of hen egg white lysozyme acquired at various stages of HD exchange. Prior information about the concentration matrix and the spectral features of the individual components was incorporated into the Bayesian equation to eliminate the ill-conditioning of the problem caused by 100% correlation of the concentration profiles of protonated and deuterated species. Secondary structure fractions obtained by partial least squares (PLS) and least squares support vector machines (LS-SVMs) were used as the initial guess for the Bayessian source separation. Advantages of the PLS and LS-SVMs methods over the classical least squares calibration (CLSC) are discussed and illustrated using the DUVRR data of the prion protein in its native and aggregated forms., (Copyright (c) 2010 Elsevier Inc.

Understanding fibrillogenesis at a molecular level requires detailed structural characterization of amyloid fibrils. The combination of deep UV resonance Raman (DUVRR) spectroscopy and post mortem hydrogen-deuterium exchange (HX) was utilized for probing parallel vs antiparallel beta-sheets in fibrils prepared from full-length Abeta(1-40) and Abeta(34-42) peptides, respectively. Using previously published structural data based on solid-state NMR analysis, we verified the applicability of Asher's approach for the quantitative characterization of peptide conformation in the Abeta(1-40) fibril core. We found that the conformation of the parallel beta-sheet in the Abeta(1-40) fibril core is atypical for globular proteins, while in contrast, the antiparallel beta-sheet in Abeta(32-42) fibrils is a common structure in globular proteins. In contrast to the case for globular proteins, the conformations of parallel and antiparallel beta-sheets in Abeta fibril cores are substantially different, and their differences can be distinguished by DUVRR spectroscopy.

PAPf39 is a 39-residue peptide fragment from the sequence of human prostatic acidic phosphatase. This peptide was shown to form amyloid-like fibrils, which have been implicated in facilitating semen-mediated HIV transmission. Thus understanding molecular details of PAPf39 peptide fibril formation may aid in elucidating the mechanism of how PAPf39 fibrils are involved in HIV etiology. To this end, the kinetics of PAPf39 peptide fibrillization was studied using a battery of biophysical methods (atomic force microscopy, ThT fluorescence assays, far-UV circular dichroism spectroscopy, deep-UV resonance Raman spectroscopy, size exclusion chromatography, analytical ultracentrifugation, and small-angle X-ray scattering). It has been shown that fibril formation follows a nucleation-dependent elongation mechanism. Several critical factors for fibrillization have been identified. It was shown that agitation and/or seeding is required for fibril formation at 37 degrees C and neutral pH, with an additional requirement of a salt concentration above approximately 100 mM. Fibril formation by the PAPf39 peptide is inhibited by low pH or by low salt concentration at neutral pH. These observations suggest that the nucleation and fibrillization of the PAPf39 peptide are a tug-of-war between the interactions formed upon agitation and the electrostatic interactions, modulated by pH and salt concentration.

A de novo 687-amino-acid residue polypeptide with a regular 32-amino-acid repeat sequence, (GA)(3)GY(GA)(3)GE(GA)(3)GH(GA)(3)GK, forms large beta-sheet assemblages that exhibit remarkable folding properties and, as well, form fibrillar structures. This construct is an excellent tool to explore the details of beta-sheet formation yielding intimate folding information that is otherwise difficult to obtain and may inform folding studies of naturally occurring materials. The polypeptide assumes a fully folded antiparallel beta-sheet/turn structure at room temperature, and yet is completely and reversibly denatured at 125 degrees C, adopting a predominant polyproline II conformation. Deep ultraviolet Raman spectroscopy indicated that melting/refolding occurred without any spectroscopically distinct intermediates, yet the relaxation kinetics depend on the initial polypeptide state, as would be indicative of a non-two-state process. Thermal denaturation and refolding on cooling appeared to be monoexponential with characteristic times of approximately 1 and approximately 60 min, respectively, indicating no detectable formation of hairpin-type nuclei in the millisecond timescale that could be attributed to nonlocal "nonnative" interactions. The polypeptide folding dynamics agree with a general property of beta-sheet proteins, i.e., initial collapse precedes secondary structure formation. The observed folding is much faster than expected for a protein of this size and could be attributed to a less frustrated free-energy landscape funnel for folding. The polypeptide sequence suggests an important balance between the absence of strong nonnative contacts (salt bridges or hydrophobic collapse) and limited repulsion of charged side chains.

In 91 patients with chronic obstructive lung disease (COLD), the severity of this disease according to the Classifications of the European Respiratory Society (ERS) and the Global Initiative on Chronic Obstructive Lung Disease (GOLD) was compared with that of pulmonary dysfunction according to the data of a comprehensive study, involving the determination of bronchial patency, lung volumes, capacities, and gas-exchange function. This follows that the ERS and GOLD classifications are to be positively appraised as they provide an eligible group of patients for clinical practice in terms of the severity of pulmonary dysfunction and that of COLD. However, the concomitant clinical use of both classifications cannot be regarded as justifiable due to that there are differences in the number of detectable grades (stages) of COLD and borderline (COLD differentiating grades (stages) values of EFV1). In this connection, both classifications have approximately equally significant merits and shortcomings and it is practically impossible to give preference to one of them as the best one. The optimal way out of the established situation is to develop a new (improved) classification of the severity of COLD on the bases of these two existing classifications.

VC, FVC, FEV1, FEV1/VC%, PEF, MEF25, MEF50, MEF75, TCL, TGV, RV, Raw, Rin, Rex, DLCO-SS, PaO2, and PaCO2 were determined in 36 patients with severe chronic obstructive lung disease (FEV1 < 50% of the normal value). All the patients were found to have impaired bronchial patency and changes in lung volumes and capacities; 83.3% of the patients had pulmonary gas exchange dysfunction. Impaired bronchial patency mainly appeared as decreased FEV1, FEV1/VC%, PEF, MEF25, MEF50, MEF75, Raw, Rin, Rex; altered lung volumes and capacities manifested by increased RV, TGV, and TLC, and by decreased VC and FVC; pulmonary gas exchange dysfunction showed up as lowered PaO2 and DLCO-SS, as decreased or increased PaCO2. The observed bronchial patency disorders varied from significant to severe; functional changes in lung volumes and capacities were mild to severe.

VC, FVC, FEV1, FEV1/VC%, PEF, MEF25, MEF50, MEF75, TCL, TGV, RV, Ravt, Riin, Rex, DLCO-SS, PaO2, and PaO2 were determined in 33 patients with mild chronic obstructive lung disease (FEV1 > 70% of the normal value). All the patients were found to have impaired bronchial patency; most (63.6%) patients had lung volume and capacity changes, almost half (45.5%) the patients had pulmonary gas exchange dysfunction. Impaired bronchial patency mainly appeared as decreased MEF50, MEF15, and FEV1/VC%; altered lung volumes and capacities manifested chiefly by increased RV and decreased VC; pulmonary gas exchange dysfunction showed up primarily as lowered PaO2. The magnitude of the observed functional changes was generally slight. MEF50, MEF75, FEV1/VC%, and VC dropped to 59-20 and 79-70% of the normal value, respectively. RV increased up to 142-196% of the normal value; PaO2 reduced up to 79-60% mm Hg.

VC, FVC, FEV1, FEV1/VC%, PEF, MEF25, MEF50, MEF75, TLC, TGV, RV, Raw, Rin, Rex, DLCO-SS, paO2 and paCO2 were determined in 22 patients with moderate chronic obstructive bronchitis (FEV1, 79-50% of the normal value). All the patients were found to have impaired bronchial patency, 90.9% of the patients had lung volume and capacity changes; pulmonary gas exchange dysfunction was present in 72.7%. Bronchial patency impairments were manifested by a decrease in FEV1, FEV1/VC%, PEF, MEF25, MEF50, MEF75, and an increase in Raw, Rin, Rex. Changes in the lung volumes and capacities appeared as higher RV, TGV, TLC, lower VC and FVC. Pulmonary gas exchange dysfunction showed up as a reduction in pO2 and DLCO-SS a reduction and an increase in paCO2. The magnitude of the functional changes observed in most patients was low. Significant and pronounced disorders were seen in one third of the patients.

In 51 patients with recurrent tuberculosis and ineffective primary treatment in intensive controlled chemotherapy, VC, FVC, FEV1, FEV1/VC%, PEF, MEF25, MEF50, MEF75, Pa02, PaCO2 were measured before, during, and after intensive controlled chemotherapy. Lung function improved in 51.0% of the patients and deteriorated in 19.6%. There was a combination of better and worse lung function in 9.8% of the examinees. The improvement of lung function was observed only during effective chemotherapy, its deterioration was seen mainly during ineffective chemotherapy, rarely during successful chemotherapy. The main cause of better lung function was the resolution of fresh inflammatory changes and that of worse lung function is the cicatricial transformation of lung tissue.

The results of a long-term (5-10 year) follow-up were studied in 109 patients with alveolitis, including 89 with EAA and 20 with IFA. A variety of treatments were applied. The predominant treatments were hormonal therapy supplemented by plasmapheresis, physiotherapy, oxygen therapy, etc. A follow-up of patients with alveolitis was made by 3 groups. Group 1 was compensated--Stage 0; Group 2, subcompensated--Stage II; Group 3, decompensated--Stage III. The control periods and scope of examinations were defined for each group. The Regulations governing the prophylactic medical examination of patients with alveolitis were worked out. Among patients with EAA, good results, such as improvement and stabilization of the process, were observed in 34.8% of cases, poor results, such as recurrences were in 53.6%, death rates were 3%. Among patients with IFA, good results were achieved in 15% of cases, recurrences and progression were in 10 and 30.7%, respectively, death rates were 40%.

VC, FVC, FEV1, FEV1/VC%, PEF, MEF25, MEF50, MEF75 were registered in 24 sarcoidosis patients before and after inhalation of 1 dose of berotec and 1 dose of atrovent. Bronchospasm took place in 20.8% patients. Bronchospasm was the only cause of bronchial obstruction in 16.7%, one of the causes in 4.2%. Contribution of bronchospasm to development of bronchial obstruction was essential in all the examinees (91-100%).

In 22 patients with exogenous allergic alveolitis, VC, FVC, FEV1/VC%, PEF, MEF25, MEF50, MEF75 were determined before and after inhalation of berotec in 1 dose and antrovent in 1 dose. Bronchospasm was detected in 50% of patients. Bronchial spasm was the sole cause of bronchial obstruction in 18.2% of patients and a cause of this disorder in 31.8%. The contribution of bronchospasm to the development of bronchial obstruction was decisive in most patients. In 42% of patients, the proportion of the former in bronchial obstruction amounted to 61-100%.

VC, FVC, FEV1/VC%, PEF, MEF25, MEF50, MEF75 were studied in 254 patients with lung diseases with bronchial obstruction before and after berotec and antrovent inhalation. Bronchospasm was detected in most patients with bronchial asthma, in a half with exogenous allergic alveolitis, in more than a third with chronic bronchitis and pulmonary tuberculosis, and in a fifth with pulmonary sarcoidosis. In most examinees with bronchospasm, the proportion of the latter in bronchial obstruction amounted to 61-100%.

In 54 new cases of tuberculosis, VC, FVC, FEV1, FEV1/VC%, PEF, MEF25, MEF50, MEF75, PaO2, PaCO2 were measured before, during, and after a short-term intensive controlled chemotherapy. Lung function improved in 57.4% of patients and deteriorated in 22.2%. There was a combination of better and worse lung function in 7.4%. The direction of functional changes depended on the form of tuberculosis, the extent of a tuberculous process, the duration and efficiency of chemotherapy.

The study has established that pulmonary dysfunctions in bronchial asthma are less marked in children and teenagers than in adults. The magnitude of pulmonary dysfunctions are chiefly determined by the severity of bronchial asthma. There was a less close relationship of pulmonary function to the duration of bronchial asthma. There was no association of the severity of pulmonary dysfunctions with the duration of bronchial asthma.

Lung capacity (LC), functional lung capacity (FLC), FEV1, FEV1/LC%, CO25, CO50, CO75 were measured in 56 patients with bronchial asthma in attach-free period before and after inhalation of one-dose berotec and one-dose atrovent. Bronchospasm was registered in 66% of the patients. It was the only cause of bronchial obstruction in 12% of the patients and one of the causes in 54% of them. Contribution of the bronchospasm to development of bronchial obstruction was, as a rule, dominating. This contribution reached 81-100% in 60% of the patients.

The paper focuses on the history and sources of origin of sanology as science, with its brief characterization being given, relating to such items as definition, object and subject of investigation, methodological approaches and tasks, with special emphasis being placed on the significance of sanology in the elaboration of general theory of medicine.

The examination of 100 patients with tuberculosis and exogenous allergic alveolitis showed it expedient to study pulmonary elastic pressure in patients without or with or X-ray signs of pneumosclerosis and pulmonary emphysema. Its exploration could diagnose initial (pre-X-ray) manifestations of pneumosclerosis and pulmonary emphysema in the former patients and specify the extent and relatively significant manifestations of these abnormalities at the subsequent (X-ray detected) stages in the others.

It is demonstrated that tuberculin electrophoresis in chemoprophylaxix for M.tuberculosis infection in adolescents with a marked of hyperergic reaction to the Mantoux test (2TU) contributes to enhancement of nonspecific immunological reactivity, to a decline in immunospecific reactions, and reduction in the response to the Mantoux test (2TU).

The complex study of the indices of local immune and natural resistance in the parietal mucus of the gastroduodenal zone and general immunity in 174 patients with duodenal ulcer disease before and after surgical treatment was performed. Pronounced suppression of local immunity, presence of autoimmune processes having influence on its indices were noted. After the organ-preserving operations with an ulcer excision, the immune indices restored more rapidly than after gastric resection and vagotomy without an ulcer excision.

The incidence of podagric nephropathy in different age groups was studied on a large populational material (41,452 persons over 30 years). The number of patients suffering from podagra was shown to increase with each decade of life. In 122 patients with podagric nephropathy, deviations in urinalyses were recorded in 80 cases (65.5%). Of these, 53 patients (72.6%) were ot 60 years of age and older. In patients over 60, derangement of nitrogen-excretory renal function was seen more frequently (in 64.4%) than in other age groups. The greater incidence of podagra and podagric nephropathy over the recent decade may be related not to the changes in the nutrition pattern and hypodynamia but also, and possibly to a larger measure, with deterioration of the environmental conditions and alterations in radiation background.

Overall 38 patients suffering from exogenous allergic alveolitis of tobacco growers including 28 with alveolitis running its course by the type of bronchitis, 8 with alveolitis which ran its course by the type of bronchial asthma, and 6 with alveolitis running its course by the type of recurrent pneumonia were examined. In all the three variants of alveolitis, the obstructive syndrome associated with pulmonary hyperinflation was predominant in the picture of the functional parameters. Marked restriction of the lungs was recorded in rare cases, the decrease of the diffusion lung capacity was mainly detected by the steady state method. Arterial hypoxemia was detectable at rest and during physical exercise. Distributive disorders turned out to be the main cause of hypoxemia.

Desympathization of the uterus in albino rats increased the intensity of 3H-estradiol inclusion into its tissues, while division of the parasympathetic nerves on the contrary, reduced it. Both types of denervation prevent increase of the cAMP and cGMP content in the organ under the effect of estradiol. Thus, the neural influences and the effect of estradiol in the uterine tissues are related. Neuromediator mechanisms evidently play a role in realization of the late cAMP- and cGMP-dependent effects of estrogens.
