Abstract: S., Objective: To study an influence of the adamantane derivative hemantane on the electrical activity of the brain structures of mice at the early and late (severe) stages of experimental modeling of Parkinson's disease (PD)., Material and Methods: For experimental modeling of PD in C57BL/6J mice, 30 male C57BL/6J mice weighing 25-32 g were systemically (intraperitoneally) administered proneurotoxin MPTP in two modes corresponding to different clinical stages of the disease: 1-methyl-4-phenyl-1.2.3.6-tetrahydropyridine (MPTP) at a dose of 12 mg/kg, 4 times and 20 mg/kg, 4 times with an interval of 2 hours, respectively., Results: At the early and late clinical stages of experimental modeling of PD in the brain structures of mice (sensorimotor cortex, substantia nigra, caudate nucleus), EEG desynchronization, an increase in wave amplitude, and an increase in the power spectrum in the range of delta frequencies and beta frequencies are observed at the late symptomatic stage experimental model of PD along with a decrease in electrical activity in the range of 4-12 Hz. Preliminary application of the adamantane derivative hemantane at a dose of 20 mg/kg, both in the early and late clinical stages of PD, prevented an excessive increase in the amplitudes of all groups of waves, normalized theta activity in the range of 4-12 Hz, reduced pathological slowing and dysregulation activity in the ranges delta and beta waves, with the prevalence of these effects in the substantia nigra of the brain of animals., Conclusion: The effect of hemantane is more pronounced at the early clinical stage of experimental modeling of PD than at the later (full-scale) stage.

Aim: Study the frequency of occurrence of antibiotics resistant strains of various species of Corynebacterium non diptheriae., Materials and Methods: C.pseudodiphtheriticum, C.pseudo- tuberculosis, C.xerosis, C.amycolatum, C.striatum, C. ulcerans strains isolated from patients with pathologies of respiratory and urogenital tract, as well as individuals taking prophylaxis ex- amination were used. Sensitivity to antibacterial preparations was determined by the serial dilution method., Results: The highest number of Coryniebacterium non diptheriae strains dis- played resistance to benzylpenicillin (54.8%) and lincomycin (50.7%), and lowest - to cefotaxime, cefazolin (6.8%) and vancomycin (13.7%). The highest number of antibiotics resistant strains were detected among members of C.pseudotuberculosis (100%), C.xerosis (96.0%) and C. pseudodiphtheriticum (81.0%) species. Polyresistant strains were detected most frequently among C.xerosis, C.amycolatum and C.striatum species. Strains of Corynebacterium non diptheriae most frequently displayed resistance to 1 or 2 antibacterial preparations (24.7%), less frequently - to 3 (20.5%); 4 (13.7%), 5 (4.1%) and 6 (1.4%) preparations., Conclusion: The amount of antibiotics resistant strains of Cdrynebacterium non diptheriae is large (89.0%) and non-similar in various species.

In a review of the features of the bacterial cells are Corynebacterium structure: characterized by an upper layer, highly organized cell wall, cytoplasmic membrane, cytoplasm, nucleoid. Described in detail the structure of the upper layer containing pili (fimbriae), microcapsule surface proteins - PS-2, DIP1281, 67-72r protein (hemagglutinin), porins, sialidase (neuraminidase). These components are the ability to initiate a serial of Corynebacterium work with the host cell, followed by colonization. It submitted a detailed description .of the structure and functions of cell wall structures - cord factor, which is a second barrier permeability; arabinogalactan, peptidoglycan, lipomannan and lipoarabinomannan. The structure and function of the cytoplasmic membrane as the main diffusion barrier cell cytoplasm and the genome of Corynebacterium. Presented differ- ent molecular genetic methods for the identification and differentiation of closely related species of Corynebacterium.

The purpose of study is to analyze sensitivity of various species Corynebacterium non diphtheriaе to antibacterial pharmaceuticals. The strains of C. non diphtheriae are separated from patients with pathology of respiratory and urogenital tract and also from individuals subjected to preventive examination. The sensitivity to antibacterial pharmaceuticals was determined using technique of serial dilution in fluid growth medium on the basis values of minimal inhibitory concentration (mg per l). It is established that the most efficient antibacterial pharmaceuticals in the case of strains C. non diphtheriae proved to be Vancomycin, Cefazolin and Cefotaxime in general. In case of such particular species as С. pseudodiphtheriticum -- Cefazolin, Cefotaxime and Gentamycin; С.pseudotuberculosis -- Vancomycin, Cefazolin, Cefotaxime and Gentamycin; C. xerosis -- Cefotaxime; С.striatum -- Cefazolin and и Rifampicin. The least efficiency was manifested for strains C. non diphtheriae by Benzylpenicillin and Lincomycin in general. In case of such particular species as С. pseudodiphtheriticum and С. pseudotuberculosis -- Lincomycin and Erythromycin; C. xerosis and С. striatum -- Benzylpenicillin, Lincomycin and Erythromycin. In case of various species of C. non diphtheriae Сephalosporins (Cefotaxime and Cefazolin) can be recommended as pharmaceuticals of choice and Gentamycin and Vancomycin as reserve pharmaceuticals., Competing Interests: The authors declare no conflict of interest.

Pathogenicity factors of Corynebacterium non diphtheriae - pili, microcapsule, cell wall, pathogenicity enzymes, toxins, that determine the ability of microorganisms to consequentially interact with epithelium of entry gates of the organism, replicate in vivo, overcome cell and hu- moral mechanisms of protection, are examined in the review. Particular attention in the paper is given to species of non-diphtheria corynebacteria, that are pathogenic for human and able to produce toxins - Corynebacterium ulcerans and Corynebacterium pseudotuberculosis. Mechanisms of expression regulation of PLD-exotoxins, its interaction with immune system cells are described.

The proper identification of Corynebacterium non diphtheriae is complicated by their wide species variety, variable biochemical activity, large spectrum of diseases at which they are isolated and also by their presence in normal human micro-flora. The bacteriological method is a traditional basis for identification of corynebacteria though long (7-14 days), produces ambiguous results at cultivation of lipophilic and biochemically variable species. For final identification of nondescript species of Corynebacterium non diphtheriae it is recommended to carry out molecular genetic study using golden standard - sequencing on 16S pRNA (DNA), genes rpoB and PLD.In case of receiving of ambiguous responses of sequencing on 16S pRNA precise identification is achieved by sequencing of secondary gene rpoB that permits discovering unique differences in sequences of genomes in different species of corynebacteria (presence of genes of virulence; absence of cluster of genes responsible for production of number of saccharolytic enzymes; presence of genes coding synthesis of particular pigments, etc.). The mass-spectrometric analysis (MALDI-ToF-MS) applied for screening identification of Corynebacterium, is simple in implementation, though requires further development for more accurate differentiation of closely-related species. The poly-phase approach to identification of Corynebacterium non diphtheriae is needed which is to include chemotaxonomic, phenotypic, genotypic information required for reliable description of new clinically significant species of corynebacteria.

The comparative analysis was carried out concerning effectiveness of three techniques of identification of Corynebacterium non diphtheriae: bacteriological, molecular genetic (sequenation on 16SpRNA) andmass-spectrometric (MALDI-ToFMS). The analysis covered 49 strains of Corynebacterium non diphtheriae (C.pseudodiphheriticum, C.amycolatum, C.propinquum, C.falsenii) and 2 strains of Corynebacterium diphtheriae isolated under various pathology form urogenital tract and upper respiratory ways. The corinbacteria were identified using bacteriologic technique, sequenation on 16SpRNA and mass-spectrometric technique (MALDIToF MS). The full concordance of results of species' identification was marked in 26 (51%) of strains of Corynebacterium non diphtheriae at using three analysis techniques; in 43 (84.3%) strains--at comparison of bacteriologic technique with sequenation on 16S pRNA and in 29 (57%)--at mass-spectrometric analysis and sequenation on 16S pRNA. The bacteriologic technique is effective for identification of Corynebacterium diphtheriae. The precise establishment of species belonging of corynebacteria with variable biochemical characteristics the molecular genetic technique of analysis is to be applied. The mass-spectrometric technique (MALDI-ToF MS) requires further renewal of data bases for identifying larger spectrum of representatives of genus Corynebacterium.

Objective: to analyze two female cases of Vogt-Koyanagi-Harada (VKH) syndrome., Material and Methods: The first patient presented with bilateral panuveitis and unilateral keratomalacia (left eye). For the latter, blepharorrhaphy was performed. Methylprednisolone (Metypred) and azathioprine pulses, subsequently switched to oral therapy, caused regression of uveitis. In 1 month the patient was operated for retinal detachment and associated cataract in her right eye. The second patient presented with bilateral detachment of neuroepithelium. Complete reattachment in both eyes was achieved with Metypred pulses followed by oral prednisolone and azathioprine. Bilateral panuveitis with pupil occlusion developed 6 months after the cessation of prednisolone, however, began to resolve as soon as the treatment was resumed., Results: Timely diagnosis and combination pulse therapy (methylprednisolone and azathioprine) enabled rapid resolution of acute condition., Conclusions: Pulse Metypred is the mainstay of the treatment of VKH syndrome. Supplementing the treatment of autoimmune uveitis with low doses of azathioprine slows progression of the disease and minimizes prednisolone-induced side effects. It is important that VKH patients are treated with pathogenetic therapy in close cooperation with an immunologist. Long-term monitoring (not less than 2-3 years) is also necessary.

Aim: To elucidate the safety profile and symptom-modifying effect of Alflutop and diacerein in the treatment of Kellgren-Lawrence Stages II-III knee osteoarthrosis (OA) in patients with oxalate nephropathy and Stages I-II chronic kidney disease (CKD) and to refine the effect of these drugs on urinary syndrome and renal function as compared to a response to nonsteroidal anti-inflammatory drugs--cyclooxygenase inhibitors (diclofenac)., Subjects and Methods: This open-label comparative randomized trial enrolled 86 female patients with Kellgren-Lawrence Stages II-III primary gonarthritis concurrent with oxalate nephropathy and Stages I-II CKD. The patients were randomized into 3 groups: 1) 20 patients took diclofenac sodium 100 mg/day; 2) 30 received a complex pharmaceutical on the basis of glycozaminoglycans Alflutop injection 1 ml per day for 20 days, then 2 ml intraartricular twice weekly in the following month; 3) 36 had diacerein (diaflex, "Rompharm Company") in a dose of 50 mg twice daily for 3 months. On day 30 and day 90 of treatment, the symptom- modifying effect was evaluated from changes in the joint pain and morning stiffness domains of the WOMAC index. Renal function was measured using the estimated glomerular filtration rate (GFR), uric acid clearance (C(ua)), and urinary sediment., Results: On day 30 of treatment, the patients taking diclofenac were found to have nephrotoxic effects (lower GFR, C(ua), evolving secondary hyperuricemia, progressive proteinuria, emerging microhematuria, elevated urinary levels of total lipid hydroperoxides, and enhanced calcium oxalate crystalluria). Alflutop and diacerein exerted no negative effects on renal function. On day 30 day of treatment, all the patient groups showed a reduction in the WOMAC pain score. The diclofenac group displayed a more marked decrease in the pain score than did the two other groups by day 30. Otherwise by day 90 of therapy with Alflutop and diacerein, the pain scores were reduced by 60 and 67%, respectively, which was similar to those in the diclofenac group by day 30 of a follow-up. By day 30 day of treatment, the stiffness score was also observed to fall in all the groups and achieved even lower values in the Alflutop and diacerein groups compared with diclofenac group., Conclusion: Alflutop and diacerein used by patients with knee OA do not produce nephrotoxic effects and by day 90 demonstrated similar to diclofenac symptom-modifying effect by reducing pain and stiffness scores. Diclofenac administration contributed to oxalate nephropathy progress.

Aim: Determine the ability of Corynebacterium non diphtheriae to induce phagocytosis and apoptosis of macrophages and evaluate regulatory effect of nuetrophilokines (NPK) induced by Corynebacterium non diphtheriae on these processes., Materials and Methods: The ability of Corynebacterium non diphtheriae, isolated from upper respiratory tract, skin and urogenital tract (UGT) were studied for the ability to induce phagocytosis and apoptosis of mice macrophages (MP; in vitro during staining by May-Grunwald with additional staining by Romanowsky-Giemsa) before and after the addition of NPK induced by Corynebacterium non diphtheriae., Results: Phagocytic index (PI) was the same for all the Corynebacterium non diphtheriae species, phagocytic number (PN) and index of phagocytosis completion (IPC)--were minimal relative to corynebacteria isolated from UGT. All the studied corynebacteria species induced MP apoptosis; the most pronounced apoptogenic effect was detected in Corynebacterium pseudotuberculosis isolated from UGT. NPK increased PN against corynebacteria isolated from the studied biotopes, IPC--only during studies of corynebacteria isolated from skin. The effect of NPK resulted in a reduction of apoptogenic effect for almost all the Corynebacterium non diphtheriae, regardless of the isolation location., Conclusion: A pronounced apoptogenic effect and insufficiency of phagocytosis processes induced by corynebacteria are the means of realization of Corynebacterium non diphtheriae pathogenic effect. NPK use is possible for immune correction of immune deficiency conditions developing against the background of diseases determined by Corynebacterium non diphtheriae.

The article deals with the results of study of sensitivity of strains of Corinebacterium non diphtheriae circulating in Rostov-on-Don and Rostov oblast to antibacterial preparations. The strains of Corinebacterium non diphtheriae isolated from urogenital tract (C. xerosis, C. pseudotuberculosis. C. amycolatum, C. striatum) are analyzed. The sample of 41 strains of C. non diphtheriae was used to detect the sensitivity to 9 antibacterial preparations. The technique of serial dilutions in liquid growth medium was applied. The range of variations (minimal suppressive concentration) of preparations as related to C. non diphtheriae made up 0.003-20.0 mkg/ ml. The results demonstrated that C. non diphtheriae are: highly sensitive to gentamycin, vancomycin and cefotaxime: sensitive to rifampicinum; and resistant to lincomicyn. In all analyzed strains of Corinebacterium non diphtheriae the greatest indicators of minimal suppressive concentration are detected in lincomicyn and at that the maximal indicator was for C. striatum and consisted 11.52 +/- 2.26 mkg/ml.

Aim: Characterize persistence properties and antibiotic sensitivity of Corynebacterium non diphtheriae circulating in Rostov-on-Don and Rostov Region., Materials and Methods: DNase, anti-immunoglobulin activity, hemagglutinating activity, antagonistic properties and antibiotic sensitivity of Corynebacterium non diphtheriae strains isolated from patients with inflammatory diseases of urogenital tract, pregnant women and individuals undertaking prophylactic examination were studied., Results: Lack of antagonistic interactions of C. non diphtheriae with members of opportunistic microorganisms, high anti-immunoglobulin activity against IgM and IgA, lack of hemagglutinating activity were established. Cefazolin and benzylpenicillin had the highest antibacterial activity against C. non diphtheriae, azithromycin and lincomycin--the lowest., Conclusion: Population level of C. non diphtheriae during urogenital tract disease diagnostics is necessary. Determination of their sensitivity to a wide specter of antibacterial preparations is reasonable for optimal selection of therapeutic agents.

The aim of the study is to make an integrated hygienic assessment of the alimentary status of pre-conscripts going to various educational establishments. Two hundred and sixty seven male leavers of general educational school and lycees were followed up. Energy needs and actual nutrition were estimated by calculation methods. Their physical development was evaluated using the standard tables. The Quetle index was used to assess the nutritional status in the youths. The daily energy needs were ascertained to be 1.64 x total metabolism unit (TMU) for schoolboys and 1.84 x TMU for lycee youths. The recommended energy expenditures were 3000 and 3350 kcal/day, respectively. The actual nutrition was shown to be inadequate to meet the energy requirements in the youths and unbalancing in the major ingredients, and characterized by the carbohydrate directionality. The Quetle index in the school and lycee leavers was 20.2 and 19.8 kg/m2, respectively. Worse physical development parameters were associated not only with inadequate nutrition, but also a static component increase in the lifestyle of the present-day youths. According to the results of the integrated assessment of the youths' alimentary status, this contingent was assigned to a risk group. A package of prophylactic measures to rationalize nutrition in studying youths is recommended.

The connection between the efficiency of phenolic lipids (PL) and their hydrophobic property (solubility) and hydrophobic property of microorganisms' cell structure is shown. The mixture of amphiphilic di(oxiphenil)-phenil-methanes, which act bacteriostatically under 15 mg/l, possesses maximal efficiency against Staphylococcus aureus. Against Mycobacterium smegmatis with hydrophobic cell wall, hydrophobic 2,4-dialkylocibenzol 70 mg/l was the most effective. Hexylresorcin (HR) stops the development of gram-positive bacteria in concentrations 20-50 mg/l, that of gram-negative bacteria in concentration 65 mg/l, that of M. smegmatis at 70 mg/l, and that of yeast and fungi at 300 mg/l. HR prevails bacteria spores germination in the concentration 25-100 mg/l. The dependence of antibacterial action of isomers and homologues of alkylresorcins on their structure--number, position, and length of alkyl substituents--is studied.

Nitrogenous metabolism, vitamin provision and anthroponietric indices were inventigated in 1560 Uzbek youths (18-21 years old) with diverse alimentary status. Changes cheatinine in urine, insufficient vitamines content and violations of authropometric indices were revald in patients with protein-calorie deficiency.

The growth characteristics of an algo-bacterial community (Chlamydomonas reinhardtii and bacterial satellites) were studied, as well as the mechanism and patterns of bacterial effect on algae. Four strains of predominant bacteria were isolated and partially characterized. They were assigned to the following taxa: Rhodococcus terrea, Micrococcus roseus, and Bacillus spp. A pure culture of the alga under study was obtained by plating serial dilutions on agarized media with ampicillin. Within the algo-bacterial association, the alga had a higher growth rate (0.76 day(-1)) and yield (60 microg chlorophyll/ml culture) than in pure cultures (0.4 day(-1) and 10 microg chlorophyll/ml culture, respectively). The viability of the algal cells within the association was retained longer than in pure culture. Among the isolated bacterial satellites, strains B1 and Y1, assigned to the species Rhodococcus terrae, had the highest stimulatory effect on algal growth. The culture liquid of bacteria incubated under the conditions not permitting growth stimulated algal growth; the culture liquid of actively growing bacteria had an opposite effect.

Energy expenditures were studied in young men when the latter performed their professional activities under extreme living conditions (strenuous exercises, a combined exposure to natural factors: high environmental temperature, longer exposure to solar ultraviolet radiation, complex piedmont relief, etc:). The average daily energy expenditure calculated by metabolic constants was 4570 kcal or 19070 kJ and the recommended calorie content of a diet is 5250 kcal.

Unilateral adrenalectomy in mice on pregnancy day 14 stimulates activity of alkaline phosphomonoesterase in placenta on pregnancy day 21. This is often accompanied with changes in the enzyme activity in fetal liver, kidneys, bone, intestine. Additional isoforms of alkaline phosphomonoesterase appear in the electrophoretic spectrum.

A clinical study showed that 2 types of changes in electrophoretic spectrum of alkaline phosphatase (AIP) isoforms are distinguished in the chorion of delivered placenta after gestosis. In type I new AIP isoforms appear, while in type II some AIP isoforms disappear or are united in one, which reflects the development of adaptation or pathological processes in the fetoplacental system.

Two stress factors, hypoxia (microaerobic conditions) and a high salt concentration, if applied simultaneously to aerobic microorganisms, display an antagonistic mode of interaction. As a result, the NaCl level that is usually optimal for moderate halophiles (5-6%) becomes optimal for the growth of weak halophiles (Rhodococcus erythropolis and Shewanella sp. CN32); the halotolerant yeast Yarrowia lypolytica acquires halophilic properties (with a growth optimum at a NaCl concentration of 10%), and the growth rate of the extremely halophilic Halobacterium salinarum increases at supraoptimal salt concentrations (25-34%). This phenomenon is apparently due to multiple changes in metabolic reactions. In particular, high salt concentrations suppress respiration and the formation of enzymes (superoxide dismutase and catalase) that protect the cell from toxic oxygen species. Therefore, establishment of microaerobic conditions compensates for the loss of these protective mechanisms and enables cell growth at higher salt concentrations than under aerobic conditions. Of some importance can also be the increase in the intracellular concentrations of osmoprotectants caused by the suppression of their intracellular oxidation. The implications of this phenomenon for the ecophysiology of microorganisms (including oiloxidizing species) and for the classification of weak and moderate halophiles are discussed.

The levels of phosphomonoesterases (acid and alkaline) in chorions of born placenta, measured by the histochemical method, reflect various phases of the pathological process in gestosis. Adaptive changes in the structure and function, paralleled by increased phosphomonoesterase activities, are replaced by decompensation, formation of destructive and necrobiotic processes, combined with suppressed phosphomonoesterase activities in stubborn severe complications of pregnancy.

The capacity of microorganisms from different taxa to adapt to stress conditions with the help of extracellular factors exhibiting similar mechanisms of action was demonstrated. The action of adaptation factors synthesized by the enteric bacterium Escherichia coli, the soil bacterium Bacillus subtilis, and the yeast Candida utilis was characterized in biological tests. It was demonstrated that the factor of accelerated adaptation to new media (FAANM) and the growth-rate-reducing factor (factor X(II)), which decreases the rate of exponential culture growth, were synthesized by all microorganisms tested. Antilysin (factor X(I)), which accelerates cell adaptation to N-ethylmaleimide, was not produced by C. utilis.

The paper shows that alkaline phosphatase activity tends to decrease in the hepatic extracts, in the intestine, significantly in the blood serum and to increase in the kidneys and significantly in the bone in mice 7 days after adrenalectomy, which coincides with the changes in the amount and activity of rapidly migrating alkaline phosphatase isoforms during polyacrylamide gel electrophoresis. Pregnancy in animals enhances alkaline phosphatase activity in the extracts of organs and tissues; adrenalectomy made on day 13-14 of pregnancy does not cause so noticeable differences as in the control group.

Evaluation of daily anergy expenditures was made on the basis of study of schoolchildren's time budget and their energy expenditures at the main body postures and during various types of activity. The data were used for substantiation of the physiological energy requirements to schoolchildren of different age and sex. Recommendations on the rations for schoolchildren with consideration for age and sex were made.

Analysis has shown that the ration of pupils mastering tractor driver profession is insufficient. Excretion of vitamins with urine in 20-68% pupils is lower than the standard. Blood protein and protein fractions content indicated a decreased protein synthesizing function of the liver. Energy expenditures of pupils are 3040-3200 kcal/d.

The peculiarities of the clinical picture in acute pneumonia in patients with sensibilization of an organism (pronounced rhino-conjunctival syndrome and more prolonged hyperthermic reaction in acute period, frequent aggravations of allergic process) require application of antiallergic therapy. Depending on the character of immunopathological reactions the complex treatment can be provided using administration of desensibilizing drugs, medications of non-specific desensibilization, natrium chromoglicate, corticosteroids, and sometimes plasmapheresis and hemosorption.

The pulmonary tissue of rats exposed to prolonged (8 days) intensive (-7 degrees C) cold was examined for the intensity of lipid peroxidation and activity of pulmonary macrophages. The data obtained during cold exposure attest to activation of the pulmonary compartment of the system of mononuclear phagocytes. Activation of lipid peroxidation in the lungs (days 1-8) associated with inhibition of the antioxidant systems (tocopherol, glutathione) is regarded as a possible mechanism of pulmonary tissue injuring by cold which stimulates the macrophagal response. A possible role of the activated forms of oxygen produced by macrophages during lipid peroxidation stimulation is discussed.

Two, twenty-four and 48 h after hydrocortisone treatment in a dose of 125 mg/kg bw the blood clearance rate for colloidal carbon particles in rats turned to be 2, 2.1. and 1.6 times less whereas that for 51Cr-SRBC in CBA mice 2.1, 2.2 and 1.7 times less as compared to untreated controls. Within 24 and 72 h after hormone injection the efficacy of red blood cell uptake by Kupffer cells decreased 1.35 and 1.8 times whereas the similar uptake by lung or spleen macrophages changed but insignificantly and that by bone marrow cells was even greater than in controls. Toward the 5th day after zymosan treatment the uptake capacity of Kupffer cells was the greatest whereas the plasma 11-OHCS content was 1.3-fold less versus the control values.

Intensive physical loading (swimming for 3.5 hours with a load amounting to 4% of body weight for rats and for 1 hour without a load for mice) reduced 5-6-fold the clearing function of the mononuclear phagocyte system of untrained animals. The absorption function of Kupffer's cells diminished 2-fold, whereas clearance through macrophages of the lung interstitium was activated. Kupffer's cells of trained animals (daily swimming for 1 hour for 10 days) acquired tolerance to loading. Preliminary administration of zymosan (3-14 days before intensive physical loading) increased the animals' resistance to stress 2-3-fold.

The effect of intensive physical exercise (swimming for 3 hours with a load of 4% body weight) on the function of hepatic, pulmonary and peritoneal macrophages has been studied in rats and mice. NBT values in alveolar and peritoneal macrophages of the experimental animals proved to be 1.5 and 1.6 times higher than in the controls. The activity of cathepsin D in the liver, lung and Kupffer cells was greater than the control values. The data obtained indicate that intensive physical exercise caused depression in phagocytic activity of Kupffer cells, the major compartment of the reticuloendothelial system, whereas a similar function in lung macrophages was even greater than in the controls and in peritoneal macrophages changed but insignificantly.

A study was made of postmortem changes in the activity of "antioxidative" enzymes and in the content of primary and secondary products of lipid peroxidation in rabbit tissues (aorta, liver). It was found that the content of primary and secondary products of lipid peroxidation in the liver sharply rises already 1.5 h after the animals were sacrificed whereas no significant changes developed in the aorta over 9 hours. The activity of the "antioxidative" enzymes in the aorta or liver remains unchanged during these hours. Possibilities are discussed of studying the activity of superoxide dismutase and glutathion peroxidase, and the products of lipid peroxidation in cadaveric material obtained on rapid autopsy of suddenly deceased people.

A study was made of lung and liver mononuclear phagocytes of rats exposed to severe cold (-7 degrees C). The data indicate the depression of mononuclear phagocytes under short-term (2 h) exposure to cold followed by activation of phagocytes, which was more demonstrable in the lungs. The phase modifications in the activity of mononuclear phagocytes were associated with accumulation of lipid peroxidation products (LPP) and destruction of alveolocytes. The different accumulation of LPP in the test organs of animals exposed to cold is regarded by the authors as a possible reason for functional differences of lung and liver macrophages.
