On the basis of the latest advances in Mayer's cluster-based approach, the reduced forms of the well-known virial expansions are derived in terms of scaled reducible and irreducible cluster integrals. This transformation minimizes the dependence on temperature and the effect of parameters specific for each thermodynamic system, thus making the resulting reduced expansions indeed universal on the quantitative level. In particular, the scaling of isotherms and saturation curves for various systems (the Lennard-Jones model, different lattice gases, and real substances with simple nonpolar molecules as well as complex polar ones) confirms the approximate universality of the proposed reduced variables for temperature, pressure, and density at subcritical gaseous states up to the saturation point.

Practically healthy persons of both genders, 23-45 years of age, with the chronic stress disorder were examined. Adaptation status was evaluated with a computer software "Anti-stress", features of bioelectric brain activity were detected by means of spectral and coherent EEG analysis, also the character of motor and sensory asymmetries was determined.

The phage-induced specific changes in the EO parameters of cell suspensions were ascertained to occur only in the E.

The effect of kanamycin on the electrophysical parameters of cell suspensions of Escherichia coli K-12 and pMMB33 was investigated. Incubation of the sensitive K-12 strain with kanamycin resulted in significant changes in the orientation spectra (OS) of the cell suspensions; these changes were not revealed in the case of the resistant pMMB33 strain. In the case of the sensitive K-12 strain incubated with different kanamycin concentrations, changes in the OS of the cell suspensions occurred within the 10-1000 kHz frequency range of the orienting electrical field.

Comparison of the obtained values with the values characteristic of healthy women and with the levels of the above reactants in patients with subacute inflammatory diseases of the uterine appendages indicated that females with IVF failures had elevated levels of lactoferrin and circulating alpha2-macroglobulin-IgG complexes and decreased concentrations of IgG as in women with a localized pyodestructive process in the appendages, but in women having effective IVF, the levels of the study proteins did not differ from those in healthy donors. The authors recommend that the above indices should be used as criteria substantiating the need for additional sanitation and anti-inflammatory therapy before initiating the IVF program.

Influence of chloramphenicol on electrophysiologic charateristics of Escherichia coli strains susceptible (K-12 strain) and resistant (pBR-325 strain) to it has been studied. It has been shown that incubation of susceptible bacteria with chloramphenicol leads to significant change of magnitute of electrooptic (EO) signal. Significant changes in orientantional spectra of suspensions of susceptible to chloramphenicol cells incubated with different concentrations of antibiotic were observed only on first five frequencies of orienting electric field (10 - 1000 kHz).

Amplipulse-magnetotherapy was used as monotherapy and in combined treatment of 110 patients with chronic nonspecific salpingo-oophoritis (CNSO). Clinical assessment shows that transcerebral amplipulse-megnetotherapy (TAMT) has a positive effects on the course of CNSO, reproductive system and psychoemotional status of the patients. The addition of physical and balneological factors to TAMT enhances and prolongs neurotropic, endocrine, analgetic and anti-inflammatory effects of TAMT.

The change in the electrooptical signal of the ampicillin-susceptible cells was maximum at an ampicillin concentration of 50 microg/ml and did not depend on the exposure time.

Essential changes in the orientation spectra (OS) of cell suspensions incubated at different concentrations of kanamycin, were found to occur only in the first 5 frequencies of the orienting electrical field (10-1,000 kHz)). The maximum change in the intensity of the electrooptical signal occurred at a concentration of kanamycin of 10 microg/ml. Antibiotic concentration of 5 microg/ml caused no changes in OS.

The study included 105 women of a reproductive age with chronic nonspecific salpingooophoritis. The women were transcerebrally exposed to interference currents (IC). The immunological examination revealed that IC have an immunocorrecting effect on both cellular and humoral links of the immune system, correct imbalance of the immunoregulatory subpopulations confirmed by increased immunoregulatory index.

The effects of transcranial electrostimulation on medical students with different types of adaptive responses (training, activation, stress, reactivation), levels of reactivity, and psychophysiological and autonomic status were studied. These experiments showed that transcranial electrostimulation was effective for subjects with adaptive responses of the training and activation types but not in those with stress combined with marked vagal tension. Transcranial electrostimulation facilitated improvements in psychophysiological parameters of the students and increased the level of body reactivity.

Neurotropic interference therapy (NIT) was studied as monotherapy and in combination with iodine-bromide water in 50 patients with chronic nonspecific salpingoophoritis. NIT was found effective in the above disease as it improved clinical picture, reproductive function, psychoemotional condition of the patients. The addition of iodine-bromide water to NIT potentiates and prolongs neurotropic, endocrine, analgetic and anti-inflammatory effects of NIT.

The influence of transcranial electrostimulation was studied in medical students considering their adaptation response type (training, activation, stress), reactivity level, psycho-physiological and vegetative status. The transcranial electrostimulation was effective in subjects with the adaptation response involving training and activation, and had no effect when stress was combined with vagotonic prevalence. The transcranial electrostimulation assists to improvement of the students' psycho-physiological indexes and to increase of their reactivity level.

74 patients with chronic salpingo-oophoritis (CS) in remission were assessed as to effects of classic massage of the uterine and epoöphoronic reflexogenic zones on clinical pattern of the disease, bioelectric activity of the abdominal muscles, spine and pelvis, blood coagulation. The combined massage produced a more potent effect on electric activity of the above muscles and blood coagulation than massage on a single area. It is better to start massage from the abdomen and continue in the lumbosacral area.
