Effects of Melatonin on Morphological and Functional Parameters of the Pineal Gland and Organs of Immune System in Rats During Natural Light Cycle and Constant Illumination.

We studied the response of the pineal gland and organs of the immune system to melatonin treatment in Wistar rats kept under conditions of abnormal illumination regimen. The animals were kept under natural light regimen or continuous illumination for 14 days and then received daily injections of melatonin (once a day in the evening) for 7 days. Administration of melatonin to rats kept at natural light cycle was followed by a decrease in percent ratio of CD4+8+ splenocytes and CD4-8+ thymocytes.

[BEHAVIOR, MEMORY AND IMMUNOLOGICAL STATUS IN MICE MODEL OF DESYNCHRONOSIS].

Interstrain differences in behavior and parameters of the immune system of CBA and C57BL/6 mice with round the clock coverage (KO) were investigated. Open field, light/dark, acoustic startle response, forced swimming, elevated plus-maze, passive avoidance were used for measuring emotional behavior and memory. The number of lymphocyte subpopulations CD3+, CD4+8-, CD4-8+, CD4+8+, CD19+, CD3+hi spleen and thymus, the ratio of cells in different phases of the cell cycle was determined by flow cytometry.

[INTERSTRAIN AND SEASONAL DIFFERENCES IN THE RESPONSE OF BLOOD AND ORGANS OF THE IMMUNE SYSTEM TO ROUND-THE-CLOCK ILLUMINATION OF CBA AND C57/BL6 MICE].

The study of the immune system of mice of CBA (n=7) and C57BL/6 (n=7) strains was performed during a 12-hour photoperiod (12:12) and round-the-clock illumination (RI) in December and March. The numbers of CD3+, CD4+8-, CD4-8-, CD4+8+, CD19+, CD3+hi lymphocyte subpopulations in the thymus and spleen, as well as the proliferative activity of thymocytes and splenocytes were measured by flow cytometry. It was found that the most pronounced.

Chrono- and Immunocorrection of Inflammatory Disorders of Internal Reproductive Organs in Women of Reproductive Age.

We compared the effectiveness of immunomodulators used in the treatment of patients with chronic salpingitis and oophoritis with or without changes in succinate dehydrogenase (SDH) activity in blood lymphocytes at incubation with the drug. Diurnal variations in individual reaction of SDH in blood lymphocytes to thymalin or ridostin were revealed. In the groups of women receiving ridostin or thymalin during the reaction of lymphocyte SDH to it, improvement of clinical laboratory and immunological parameters was observed in the majority of the patients and no effect was found in a lesser group of patients than in the groups treated with drugs during the absence of lymphocyte SDH reaction thereto.

[THE CHANGES OF THE INTERRELATIONS OF THE PINEAL GLAND AND THE ORGANS OF THE IMMUNE SYSTEM IN RATS IN RESPONSE TO MELATONIN ADMINISTRATION IN LIGHT REGIME DISTURBANCES].

In this work the correlation analysis was applied to detect the integrated response of the pineal gland (PG) and immunocompetent organs of male Wistar rats in response to administration of melatonin (MT) in light regime disturbances. Animals were kept for 14 days under natural or continuous light (CL). Then for 7 days they received the injections of either 0.

[Interrelations of pineal gland morpho-functional indices and immune system organs in rats exposed to natural illumination regime and continuous illumination].

The objective of this investigation was to determine the complex response of the pineal gland (PG) and of the organs of the immune system in Wistar rats in response to a violation of the illumination regime in the experiment. Animals were kept under natural light regime and continuous illumination for 14 days. After that rats were sacrificed and the mass of the body, PG, gonads, thymus and spleen was measured.

The influence of experimental desynchronosis on the morphofunctional characteristics of mouse immune system.

The aim of this study is to investigate the influence of experimental desynchronosis on the immune system and estimate benzo[a]pyrene (BP) influence on the immune reactivity of mice under the condition of desyncronosis (DS) in comparison with intact organisms. Mice (CBA X C57BL)F1 were kept under constant light during two weeks and natural alternation of darkness and light (control group). Animals of the two groups received benzo[a]pyrene solution in olive oil.

Circadian variations in immune values and serum melatonin in asthmatics.

Circadian variations in the immune status and serum melatonin were studied in asthmatics during exacerbation stage before and after treatment. Deviations from the normal (donor) immunogram values at 9.00 and 21.

Circadian dynamics of cell composition of the thymus and lymph nodes in mice normally, under conditions of permanent illumination, and after melatonin injection.

The effect of melatonin on disturbed circadian variations in the lymphocyte subpopulation composition of the thymus and inguinal lymph nodes was studied in CBA mice exposed to constant illumination for 14 days. The desynchronizing effect of permanent illumination on the thymus consisted in disappearance of circadian variations in the total number of thymocytes, absolute count of thymocytes, absolute counts of CD8(+) and CD4(+) cells, and in inversion of changes in the absolute counts of CD4(+)8(+) cells from 15.00 to 20.

Circadian variations of melatonin concentration in saliva and blood content of immunocompetent cells in healthy individuals.

Salivary content of melatonin and parameters of the immune status were studied in young healthy individuals. Morning and evening levels of melatonin showed different correlations with some immunity parameters. It was assumed that the degree and type of correlation between the immune system and melatonin depend on the phase of circadian cycle, which should be considered during evaluation of immunoendocrine status.

Effects of amitriptyline on diurnal variations of oxidation-reduction enzyme activities in rat lymphocytes during experimental desynchronosis.

We studied the effects of amitriptyline on diurnal variations of oxidative-reduction enzyme activities (succinate dehydrogenase, lactate dehydrogenase, and NADPH diaphorase) in rat peripheral blood lymphocytes during experimental desynchronosis. Desynchronosis was induced by constant light exposure for 14 days and manifested in a morning shift of maximum lactate dehydrogenase activity and elevated morning NADPH diaphorase activity. Amitriptyline normalized morning lactate dehydrogenase activity and diurnal variations in NADPH diaphorase activity.

Effect of amitriptyline on daily variations in cell composition of immune organs in rats with experimental desynchronosis.

We studied the effects of amitriptyline (preparation stimulating melatonin synthesis in the pineal gland) on daily variations of cell composition in immune organs of Wistar rats with experimental desynchronosis. Amitriptyline administered in the evening restored the daily dynamics of the number of thymus cells.

Changes in thymosin-alpha(1)content in patients with nonspecific gynecologic diseases depending on inflammation type and efficacy of antiinflammatory and immunomodulating therapy.

Plasma content of thymosin-alpha(1)and its circadian variations in patients with inflammatory gynecologic diseases differ from those in healthy donors and depend on the type of inflammation and efficacy of treatment. It is concluded that not only the absolute content of thymic hormones, but also their biorhythmic variations are important for immune regulation.

[Chronobiology of immune system].

The biological rhythmological programme of the immune system is a constituent of the body's common biological rhythmological programme. Its pattern seems to be genetically determined and reflects the functional status of the system. The chronobiological mechanisms responsible for the regulation of immune functions lie in the presence of certain phasic interrelations between the biological rhythms of the synthesis and production of regulatory agents on the one hand, and those of the receptor system and metabolic potential of immunocompetent cells on the other.

[Analysis of postoperative mortality in acute cholecystitis].

The analysis of lethal outcomes in 108 (3.66%) of the 2974 patients operated on for acute cholecystitis was carried out. In 40.
