[Medical rehabilitation of patients with alcohol dependency at risk of parental rights deprivation]. / Meditsinskaia reabilitatsiia bol'nykh s alkogol'noi zavisimost'iu s riskom lisheniia roditel'skikh prav.

AIM: To study the efficacy of medical rehabilitation outpatient program 'Point of Soberness' with the use of prolonged injectable naltrexone for alcohol dependent parents of minor children. MATERIAL AND METHODS: One hundred and seventeen patients with severe disease form without remissions were enrolled in the study. All patients were parents at risk of deprivation of parental rights. RESULTS AND CONCLUSION: A complex approach, used during the rehabilitation, helped 87% of patients to maintain social and professional status and finish treatment program. More than 95% of patients retained their parental rights. The 'Point of Soberness' program allows achievement of remission of alcohol dependence and retaining parental rights.

Study of η and η' Photoproduction at MAMI.

The reactions γp→ηp and γp→η^{'}p are measured from their thresholds up to the center-of-mass energy W=1.96 GeV with the tagged-photon facilities at the Mainz Microtron, MAMI. Differential cross sections are obtained with unprecedented statistical accuracy, providing fine energy binning and full production-angle coverage. A strong cusp is observed in the total cross section for η photoproduction at the energies in the vicinity of the η^{'} threshold, W=1896 MeV (E_{γ}=1447 MeV). Within the framework of a revised ηMAID isobar model, the cusp, in connection with a steep rise of the η^{'} total cross section from its threshold, can only be explained by a strong coupling of the poorly known N(1895)1/2^{-} state to both ηp and η^{'}p. Including the new high-accuracy results in the ηMAID fit to available η and η^{'} photoproduction data allows the determination of the N(1895)1/2^{-} properties.

Insight into the Narrow Structure in η Photoproduction on the Neutron from Helicity-Dependent Cross Sections.

The double polarization observable E and the helicity dependent cross sections σ_{1/2} and σ_{3/2} were measured for η photoproduction from quasifree protons and neutrons. The circularly polarized tagged photon beam of the A2 experiment at the Mainz MAMI accelerator was used in combination with a longitudinally polarized deuterated butanol target. The almost 4π detector setup of the Crystal Ball and TAPS is ideally suited to detect the recoil nucleons and the decay photons from η→2γ and η→3π^{0}. The results show that the narrow structure previously observed in η photoproduction from the neutron is only apparent in σ_{1/2} and hence, most likely related to a spin-1/2 amplitude. Nucleon resonances that contribute to this partial wave in η production are only N 1/2^{-} (S_{11}) and N 1/2^{+} (P_{11}). Furthermore, the extracted Legendre coefficients of the angular distributions for σ_{1/2} are in good agreement with recent reaction model predictions assuming a narrow resonance in the P_{11} wave as the origin of this structure.

[Pychotherapy in patients with alcohol dependence and comorbid endogenous pathology]. / Psikhoterapiia bol'nykh s alkogol'noi zavisimost'iu i komorbidnoi éndogennoi patologiei.

AIM: To develop differential psychotherapeutic methods in the combined treatment of patients with alcohol dependence and comorbid paranoid schizophrenia. MATERIAL AND METHODS: Authors treated 154 patients using a specially designed psychotherapeutic program. The sample was randomized into the experimental and control groups. The experimental group received the psychotherapeutic program in contrast to the control group. RESULTS: The psychotherapeutic program based on the treatment of alcohol-dependence symptoms and patterns of coping with mental disorder symptoms was effective for the patients. Participation in the program allowed patients with alcohol dependence and comorbid schizophrenia to reduce manifestations of pathological craving for alcohol. CONCLUSION: The appropriate psychopharmacotherapy of endogenous disorder symptoms is an essential condition for successful psychotherapy, especially at the beginning of the treatment.

Measurements of double-polarized compton scattering asymmetries and extraction of the proton spin polarizabilities.

The spin polarizabilities of the nucleon describe how the spin of the nucleon responds to an incident polarized photon. The most model-independent way to extract the nucleon spin polarizabilities is through polarized Compton scattering. Double-polarized Compton scattering asymmetries on the proton were measured in the Δ(1232) region using circularly polarized incident photons and a transversely polarized proton target at the Mainz Microtron. Fits to asymmetry data were performed using a dispersion model calculation and a baryon chiral perturbation theory calculation, and a separation of all four proton spin polarizabilities in the multipole basis was achieved. The analysis based on a dispersion model calculation yields γ(E1E1)=-3.5±1.2, γ(M1M1)=3.16±0.85, γ(E1M2)=-0.7±1.2, and γ(M1E2)=1.99±0.29, in units of 10(-4) fm(4).

Measurement of the transverse target and beam-target asymmetries in η meson photoproduction at MAMI.

We present new data for the transverse target asymmetry T and the very first data for the beam-target asymmetry F in the γ[over →]p[over →]→ηp reaction up to a center-of-mass energy of W=1.9 GeV. The data were obtained with the Crystal-Ball/TAPS detector setup at the Glasgow tagged photon facility of the Mainz Microtron MAMI. All existing model predictions fail to reproduce the new data indicating a significant impact on our understanding of the underlying dynamics of η meson photoproduction. The peculiar nodal structure observed in existing T data close to threshold is not confirmed.

Between-group differences in personality changes, specifics of the alcohol-use component of the comorbid disorder and responsiveness to psychotherapy are shown.

[Adenosine deaminase in the blood cells and serum of patients with tuberculous pleurisy].

The common complication of pulmonary tuberculosis is pleurisy that requires not only special treatments, but also gives rise to difficulties in the differential diagnosis of tuberculosis. The investigation has studied the possibility of determining the activity of adenosine deaminase (ADA) as a marker of pleural effusion of tuberculous etiology. The patients with tuberculous pleurisy have been found to have higher lymphocytic and red blood ADA, and ADA, activities and a significantly increased serum ADA2 activity. Thus, the changes in the activity of ADA and its isozymes have been shown to be specific to pleurisy of tuberculous etiology and to be of diagnostic value.

[Impact of endogenous porphyrin-photosensitized exposure on peripheral lymphocytes in patients with pulmonary tuberculosis].

Peripheral lymphocytes (PL) were studied in 63 patients with pulmonary tuberculosis and 28 donors. The study revealed the elevated levels of lipid peroxidation products, altered membrane potential, and diminished PL viability in patients with pulmonary tuberculosis as compared with healthy donors. Analysis of the time dependences of cell viability and production of active tuberculosis products after endogenous porphyrin-photosensitized exposure suggests that the lymphocytes from patients with pulmonary tuberculosis are more exposed to the damaging effect of free radicals than the cells from healthy individuals. This is more apparent 18 hours of dark incubation after cell illumination in the presence of ALK-induced porphyrins in doses of 47.4 kJ/m2 or more. The findings suggest that the changes occurring in PL from patients with pulmonary tuberculosis may substantially cause immune disorders and contribute to the progression of a tuberculous process.

[Differential diagnosis significance of measuring surfactant phospholipid levels in lung diseases]. / Differentsial'no-diagnosticheskoe znachenie opredeleniia soderzhaniia fosfolipidov surfaktanta pri zabolevaniiakh legkikh.

The levels of surfactant phospholipid from bronchoalveolar lavage were measured in 70 patients with pulmonary diseases and in 10 apparently healthy individuals. The levels of surfactant phospholipid components were lower in patients with peripheral lung cancer, infiltrative tuberculosis, focal pneumonia, most significant in cancer; differential diagnostic criteria for these diseases are defined.

Natural and probe fluorescence of lymphocytes of patients with pulmonary tuberculosis exposed to radiation as a result of the Chernobyl nuclear accident.

Parameters of natural and probe fluorescence of peripheral blood lymphocytes have been studied in 25 normal persons and 72 patients suffering from extensive forms of pulmonary tuberculosis who live in various radioecological conditions. It was found that in cell suspension the intensity of fluorescence of protein and the membrane-bound merocyanine 540 dye was 2.0-3.2 and 3.9-7.1 times higher, respectively, for the lymphocytes of the examined patients. For lymphocytes of the patients who live in radionuclide-contaminated areas fluorescence of reduced pyridine nucleotides and some fluorescent probes (ANS, DPGT, the ratio of eximer to monomer fluorescence of pyrene) and the merocyanine-photosensitized cell death were also found to increase. These can indicate some changes of cell membranes and reduction of the oxidation resistance of lymphocytes. There was not any substantial dependence on the changes in the parameters determined in the patients calculated radiation doses was revealed. It was found that biophysical tests, in particular, photosensitized cell death, are informative for estimation of severity of the tuberculous process and prognosis of its outcome in patients who live in adverse radioecological conditions.
