Data characterizing the kinetics of the contraction of trabeculae and the intertrabelcular tissue have been obtained. It has been concluded that trabeculae can act as conductors/transmitters of contraction across the myocardium and play a leading role in this process, while the functional role of the intertrabelcular tissue is secondary and more passive, and consists in the optimization and support of the contractile process.

Virological and molecular genetic studies of the field material collected in the epicenter of epizooty with high mortality rates among the wild birds on the coast of the Ubsu-Nur lake (Republic of Tyva, 51 degrees NL, 93 degrees EL, June 2006) revealed the etiological role of highly pathogenic avian influenza (HPAI) H5N1. Seven HPAI/H5N1 strains were isolated from the tracheal/cloacal swabs of clinically healthy, ill and recently dead great-crested grebes (Podiceps cristatus), cormorants (Phalacrocorax carbo), balt-coots (Fulica atra), and common terns (Sterna hirundo) collected on June 24, 2006, and incorporated to the RF State Collection of Viruses (with the July 3, 2006 priority). Full-length genome nucleotide sequences were incorporated to the GenBank (with the July 23, 2006 priority) (DQ852600-DQ852607).

The character of immune disturbances was studied in women with tuboperitoneal infertility associated with a chlamydial infection. The immunological methods included a study of the population and subpopulation composition of peripheral blood lymphocytes (CD3, CD7, CD22, CD4, CD8, ratio CD4/CD8). The general hemolytic activity of the complement and main components of the complement (C1-C5), the level of IgA, IgM, IgG, the concentration of CIC, the content of IL-2 and its soluble receptor (sIL-2R) were determined in blood serum and in peritoneal fluid before and after treatment.

The population and subpopulation composition of peripheral blood lymphocytes of 33 women was studied in the dynamics of non-complicated pregnancy by the method of flow cytofluorometry with the use of equipment and reagents supplied by Becton Dickinson, Inc. This study revealed that the non-complicated course of pregnancy was characterized by the adequate reaction of the mother's immune system ensuring the physiological development of the fetus during pregnancy and timely labor.

The etiological structure of the inflammatory diseases of genitals at different levels of the reproductive tract of women with tuboperitoneal sterility was studied. The study revealed the prevalence of cocci in the cervical canal, anaerobes in the endometrium and chlamydiae in the abdominal cavity (peritoneal fluid, the ovarian capsule, fimbriated ends), as well as the presence of mixed infection in 27% of the patients under study. The specific features of immunity in women with tuboperitoneal sterility were established, which determined the main trends of the subsequent pathogenetically oriented immunocorrection.

A total of 145 women with chronic inflammatory diseases of uterus and appendages (IDUA) were examined. Bacterioscopy of smears and culture of vaginal, cervical canal and uterine cavity contents were performed in all patients. Direct immunofluorescence and PCR were used for detection of chlamydiae in scrapes and smears and in biopsy specimens taken from endometrium.

The character of microflora, directly causing inflammatory process in tuboperitoneal infertility, was studied. The study revealed the prevalence of microbial associations, Chlamydia infection was detected in half of the women, and in 17% of the patients this infection was for the first time detected in the upper section of their reproductive apparatus, which was indicative of the role of Chlamydia infection in the occlusion of the uterine tubes. Opportunistic microflora persisting in persons with defective antimicrobial protection was found.

Local immune reactions in 107 women with Chlamydia-associated chronic endometritis and salpingo-oophoritis were studied on endometrial biopsy specimens. Of these women, group 1 consisted 45 patients with Chlamydia-associated chronic endometritis and salpingo-oophoritis and group 2 consisted of 62 such patients having, in addition, bacterial vaginosis and candidiasis. Among associated bacteria, epidermal staphylococci, Escherichia coli and their combinations prevailed.

The correlation between the characteristics of K(+)-transport across the mitochondrial and bilayer lipid membranes formed form mitochondrial lipids has been demonstrated. It has been shown that different modes of K(+)-efflux activation in mitochondria result in the appearance of K(+)-transporting phospholipid forms. The experiments described in this work suggest that current fluctuations similar to those observed for biological channels can be registered in unmodified bilayer lipid membranes containing no protein components.

Using the procedure of lysis by ammonium chloride followed by differentiation centrifuging, the fraction of cells containing polymorphonuclear leucocytes was isolated from the whole rat blood to study the conditions of optimal production of oxygen forms was determined from the chemiluminescent cell response in the presence of luminol. It was shown that chemiluminescent cell response depends on the temperature, pH and osmolarity of the medium as well as on the presence of various concentrations of Ca2+ in the incubation medium. The maximal chemiluminescent response of polymorphonuclear leucocytes was observed at 35-37 degrees C, pH 7,6, osmolarity of 0,15 and Ca2+ concentration of 5-10 mM.

Immunologic homeostasis was studied in 272 women suffering from sterility of a tuboperitoneal and mixed origin. The detected drastic disorders of immunologic homeostasis were characterized by predominant disorders of primary immunity mechanisms (leukopenia, monocytopenia, lymphopenia, reduced concentrations of IgA and IgM, lysozyme and complement in the blood serum). Types II, III, and IV immunopathologic reactions to uterine tube tissue homologous antigen suggest their contribution to a chronic inflammatory process.

The incidence of chlamydial infection in women with tuboperitoneal sterility is 49.5%. Clinically inflammatory diseases of the pelvic organs in such an infection are characterized by a primary chronic course with frequent recurrences and involvement of the cervix uteri, urethra, internal genitals, with moderately manifest clinical symptoms.

Analysis of the diagnostic and prognostic potentialities of measurements of blood serum medium molecules and medium-molecular peptides in women with inflammatory diseases of the small pelvis organs has been carried out, involving 60 patients and 10 healthy women. Medium molecule levels were estimated with the use of Gabrielyan and Lipatova's method, the level of medium-molecular peptides by the biuret method. The results recommend these measurements to be included in the complex of clinical laboratory investigations carried out in patients with pelvic inflammations for the early detection of purulent ++tubo-ovarian inflammations, endogenous intoxication, and a more rational treatment.

This paper presents a scale for the evaluation of severity of late toxemia using 15 clinical and laboratory indices as well as central and regional hemodynamic parameters obtained by whole-body rheography and poly-rheography. Interpretation of the severity of late toxemia involved findings of functional postural and pharmacological tests. The scale is recommended for its use in the obstetric practice.

Partusisten was examined for effects on uterine contractility in 28-36- or 38-42-week pregnant women and parturients. The agent was shown to result in inhibited uterine contractility in the pregnant and parturient females, the contractility was decreased before and particularly during labor, which was indicative of lower beta-adrenoreceptor inhibitory mechanism force.

In order to reveal endogenous beta-adrenomimetic in the blood the authors proposed the biological testing of the serum and plasma on the isolated myometrium of the rat. For this purpose obsidan was used as a beta-adrenoblocker. It was shown that endogenous beta-adrenomimetic different from adrenaline was present in the blood of males, nonpregnant and pregnant females and parturients.
