Abstract
Despite efforts in osteosarcoma (OS) research, the role of inductive moderate hyperthermia (IMH) in delivering and enhancing the antitumor effect of liposomal doxorubicin formulations (LDOX) remains unresolved. This study investigated the effect of a combination treatment with LDOX and IMH on Saos-2 human OS cells. We compared cell viability using a trypan blue assay, apoptosis and reactive oxygen species (ROS) measured by flow cytometry and pro-apoptotic Bax protein expression examined by immunocytochemistry in response to IMH (42 MHz frequency, 15 W power for 30 min), LDOX (0.4 μg/mL), and LDOX plus IMH. The lower IC50 value of LDOX at 72 h indicated increased accumulation of the drug in the OS cells. LDOX plus IMH resulted in a 61% lower cell viability compared to no treatment. Moreover, IMH potentiated the LDOX action on the Saos-2 cells by promoting ROS production at temperatures of <42 °C. There was a 12% increase in cell populations undergoing early apoptosis with a less heterogeneous distribution of Bax after combination treatment compared to those treated with LDOX (p < 0.05). Therefore, we determined that IMH could enhance LDOX delivery and its antitumor effect via altered membrane permeabilization, ROS generation, and a lower level of visualized Bax heterogeneity in the Saos-2 cells, suggesting the potential translation of these findings into in vivo studies.

Abstract
Magnetic nanoparticles (MNs) are typically used as contrast agents for magnetic resonance imaging or as drug carriers with a remotely controlled delivery to the tumor. However, they can also potentiate the action of anticancer drugs under the influence of applied constant magnetic (CMFs) and electromagnetic fields (EMFs). This review demonstrates the role of magneto-mechanochemical effects produced by MNs alone and loaded with anticancer agents (MNCs) in response to CMFs and EMFs for modulation of tumor redox state. The combined treatment is suggested to act by two mechanisms: spin-dependent electron transport propagates free radical chain reactions, while magnetomechanical interactions cause conformational changes in drug molecules loaded onto MNs and generate reactive oxygen species (ROS). By adjusting the parameters of CMFs and EMFs during the magneto-mechanochemical synthesis and subsequent treatment, it is possible to modulate ROS production and switch redox signaling involved in ERK1/2 and NF-κB pathways from initiation of tumor growth to inhibition. Observations of tumor volume in different animal models and treatment combinations reported a 6%-70% reduction as compared with conventional drugs. Despite these results, there is a general lack of research in magnetic nanotheranostics that link redox changes across multiple levels of organization in the tumor-bearing host. Further multidisciplinary studies with more focus on the relationship between the electron transport processes in biomolecules and their effects on the tumor-host interaction should accelerate the clinical translation of magnetic nanotheranostics. This article is categorized under: Therapeutic Approaches and Drug Discovery > Nanomedicine for Oncologic Disease Therapeutic Approaches and Drug Discovery > Emerging Technologies Nanotechnology Approaches to Biology > Nanoscale Systems in Biology.

Abstract
OBJECTIVE This study aimed to determine whether texture parameters could be used in differentiation between the tumor and the peritumoral tissues based on hybrid 18F-Fluorodeoxyglucose positron emission tomography/computed tomography imaging for patients with rectal cancer. METHODS Seven parameters, including heterogeneity, entropy, energy, skewness, kurtosis, standard deviation, and average brightness, were extracted from positron emission tomography/computed tomography scans of 22 patients (12 male and 10 female; mean age, 61 ± 2 years). RESULTS The peritumoral tissue had a significantly lower value of the heterogeneity parameter (23%) than the tumor. Tumor size (r = -0.48, P < 0.05) and extramural venous invasion scores (r = 0.64, P < 0.05) correlated with heterogeneity in the peritumoral tissue. There were significant differences (P < 0.05) in the correlation coefficients between men and women. CONCLUSIONS Therefore, we provided additional quantitative information to differentiate the tumor from the peritumoral tissue and indicated possible application for extramural venous invasion evaluation in rectal cancer.

Abstract
We compare the effects of an extremely low-frequency electromagnetic field (EMF) with the chemotherapeutic agent doxorubicin (DOX) on tumor growth and the hepatic redox state in Walker-256 carcinosarcoma-bearing rats. Animals were divided into five groups with one control (no tumor) and four tumor-bearing groups: no treatment, DOX, DOX combined with EMF and EMF. While DOX and DOX + EMF provided greater inhibition of tumor growth, treatment with EMF alone resulted in some level of antitumor effect (p < .05). Superoxide dismutase, catalase activity and glutathione content were significantly decreased in the liver of tumor-bearing animals as compared with the control group (p < .05). The decreases in antioxidant defenses accompanied histological findings of suspected liver damage. However, hepatic levels of thiobarbituric acid reactive substances, an indicator of lipid peroxidation, were three times lower in EMF and DOX + EMF groups than in no treatment and DOX (p < .05). EMF and DOX + EMF showed significantly lower activity of serum ALT than DOX alone (p < .05). These results indicate that EMF treatment can inhibit tumor growth, causing less pronounced oxidative stress damage to the liver. Therefore, EMF can be used as a therapeutic strategy to influence the hepatic redox state and combat cancer with reduced side-effects.

Abstract
Although nanotechnology advances have been exploited for a myriad of purposes, including cancer diagnostics and treatment, still there is little discussion about the mechanisms of remote control. Our main aim here is to explain the possibility of a magnetic field control over magnetic nanocomplexes to improve their delivery, controlled release and antitumor activity. In doing so we considered the nonlinear dynamics of magnetomechanical and magnetochemical effects based on free radical mechanisms in cancer development for future pre-clinical studies.

Abstract
BACKGROUND The resection of metastases within healthy parenchyma improves significantly the long-term outcome in metastatic colorectal cancer. Until now, the resection technique involves Pringle maneuver, which allows reducing blood loss during transsection of liver parenchyma. However, the classical Pringle maneuver has restrictions due to ischemia/reperfusion (I/R) effect, in particular increasing risk of tumor recurrence after liver surgery. AIM To study the pathological impact of surgical intervention and I/R effect on healthy liver tissue in the experimental setting by evaluating the markers of redox-homeostasis and oxidatively induced mutage-nesis, and also to assess the current possibilities of their correction by application of drag-reducing polymers (DRPs). MATERIALS AND METHODS MC38 mouse colon adenocarcinoma cells were transplanted intrahepatically to C57Bl/6 mice. The influence of warm ischemia on metastatic potential of MC38 cells, the speed of superoxide radicals (SR) generation and 8-hydroxydeoxyguanosine content were studied. RESULTS In case of modeled liver metastases, the surgery initiates an increase in the rate of SR generation into the remaining liver tissue and, consequently, provokes its ischemic injury. The application of DRPs protects liver tissue under I/R conditions. CONCLUSIONS The warm I/R can promotes metastatic lesions in the healthy part of the organ with underlying increase in the rate of SR generation and oxidatively induced damage of guanine in DNA. The hemorheological effects of DRPs ensure increase of microcirculatory perfusion and oxygenation of liver tissues with the reduction of the rate of SR generation and decrease of 8-hydroxydeoxyguanosine as a marker of oxidatively induced mutations in DNA of hepatocytes. The intraperitoneal administration of nanomolar doses of DRPs prevents the activation of the growth of dormant metastatic MC38 cells in the liver. Further experimental and clinical study of these substances will allow reducing the risks of activation of uncontrolled tumor growth in the liver due to the pathological effect of post-operative I/R.

Abstract
Chaos theory (nonlinear dynamics) defines cancer as a complex adaptive system in which each cyclic point corresponds to the bifurcation at which changes in signaling pathways emerge. Quantitative assessment of chaos in digital medical images such as electron microscopy, histology and cytology sections collected from patients with malignant cutaneous melanoma employed the following calculation parameters: the irregularity of external contours, internal heterogeneity based on brightness distribution of macromo-lecules, chromosomes, organelles, inclusion bodies, cells and tissues, kurtosis, entropy and the asymmetry coefficient. The present study undertook a nonlinear analysis of the chaotic hierarchy of malignant melanoma. However, considerably more studies will need to be carried out to determine the exact interrelationship between different levels of the hierarchy in the biological system. Multidisciplinary collaborations are therefore essential to find evidence to answer questions that remain open to researchers and oncologists.

Abstract
PURPOSE To evaluate the efficacy of neoadjuvant chemotherapy in combination with regional inductive moderate hyperthermia for patients with locally advanced breast cancer. PATIENTS AND METHODS 200 patients with stage IIB-IIIA breast cancer received neoadjuvant chemotherapy (control group, n = 97) or chemotherapy combined with hyperthermia (experimental group, n = 103). Inductive hyperthermia was set at 27.12 ± 0.16 MHz and the 50 W output power. RESULTS Thermal and color Doppler ultrasound imaging demonstrated that hyperthermia increased the surface temperature on the breasts to < 4°С while the mean values for systolic blood flow were 3.5 times as high as those prior to treatment. Assessment of tumor size and response found a (31.24 ± 3.85)% reduction in the size of the primary tumor in patients receiving chemotherapy + hyperthermia, while chemotherapy alone showed a (22.95 ± 3.61)% decrease on average (p = 0.034). The rate of objective response increased by 15.9% in the experimental group (р = 0.034) compared with the control group. The patients in the experimental group also had axillary lymph node regression of 14.17% greater than in the control group (p = 0.011). Moreover, the combination treatment allowed to increase the proportion of women eligible for breast-conserving and reconstructive surgery by 13.63% in the experimental group. The viable tumor volume was lower in patients receiving neoadjuvant chemotherapy + hyperthermia (24.4 ± 0.2)% compared with those given chemotherapy alone (30.4 ± 0.25)%. The 10-year overall survival rates were higher (log-rank: p = 0.009) in breast cancer patients who underwent chemotherapy combined with hyperthermia than in patients receiving chemotherapy only. CONCLUSION The combination neoadjuvant chemotherapy and the technology of regional inductive moderate hyperthermia improved the efficacy of treatment for patients with locally advanced breast cancer staged IIB-IIIA.

Abstract
The paper aims to compare zeta potentials, magnetic properties, electron spin resonance, photoluminescence (PL) spectra and antitumor effect of magneto-mechano-chemically synthesized magneto-sensitive nanocomplexes loaded with the anticancer drug doxorubicin (DOXO) during nanotherapy of Walker-256 carcinosarcoma carried out by a magnetic resonance system. Diamagnetic DOXO acquired the properties of a paramagnetic substance after synthesis. MNC comprising superparamagnetic nanoparticles (NP) and DOXO had different g-factors, zeta potentials, a lower saturation magnetic moment, area of the hysteresis loop, and a higher coercivity compared to similar MNC with ferromagnetic NP. The main PL peak of MNC spectrum was defined by DOXO at 598 nm. MNC composed of superparamagnetic NP and DOXO showed a lower standard deviation of the normal PL spectral distribution than MNC based on ferromagnetic NP in relation to conventional DOXO. MNC containing superparamagnetic NP responded to resonance conditions leading to a more pronounced antitumor effect compared to MNC with ferromagnetic NP in the course of magnetic nanotherapy for Walker-256 carcinosarcoma bearing animals (temperature inside the tumor did not exceed 40 °C). Therefore, these findings are associated with differences in chemotherapeutic effect between MNC due to a different surface charge and conformational changes in DOXO molecules during its magnetoelectric interaction with single- and multidomain NP.

Abstract
Modulation of reactive oxygen and nitrogen species in a tumor could be exploited for nanotherapeutic benefits. We investigate the antitumor effect in Walker-256 carcinosarcoma of magnetic nanodots composed of doxorubicin-loaded Fe3O4 nanoparticles combined with electromagnetic fields. Treatment using the magnetic nanodot with the largest hysteresis loop area (3402 erg/g) had the greatest antitumor effect with the minimum growth factor 0.49 ± 0.02 day-1 (compared to 0.58 ± 0.02 day-1 for conventional doxorubicin). Electron spin resonance spectra of Walker-256 carcinosarcoma treated with the nanodots, indicate an increase of 2.7 times of free iron (that promotes the formation of highly reactive oxygen species), using the nanodot with the largest hysteresis loop area, compared to conventional doxorubicin treatment as well as increases in ubisemiquinone, lactoferrin, NO-FeS-proteins. Hence, we provide evidence that the designed magnetic nanodots can modulate the tumor redox state. We discuss the implications of these results for cancer nanotherapy.

Abstract
PURPOSE Regional inductive moderate hyperthermia in combination with chemotherapy can improve the therapeutic efficacy in patients with breast cancer with multiple liver metastases. METHODS The study included 103 patients with breast cancer with multiple liver metastases: 53 patients (main group) who received a combined chemotherapy (TC drug combination) and regional inductive moderate hyperthermia treatment and 50 patients (control group) who received chemotherapy (TC drug combination) alone. Regional inductive moderate hyperthermia exploited electromagnetic fields with an operating frequency of 27.17 ± 0.16 MHz and output power of 75 W. Treatment results were assessed by computed tomography and ultrasound imaging. RESULTS Partial regression was defined as a 30% decrease in the sum of the maximum diameters of investigated tumors. In the current study, partial regression was described in 8 (15.1%) patients assigned to the main group and 2 (4%) patients in the control ( P < .05). The process stabilization was reported in 32 (60.4%) patients receiving the combined treatment and 19 (38%) in the control ( P < .05). Equally important, tumor progression was observed in 13 (24.5%) patients representing the main group and 29 (58%) in the control. During a 30-minute treatment session, a temperature increase overlaying greater than 90% of the liver projection exposed to electromagnetic irradiation was not exceeding 40°C. CONCLUSION The combined regional inductive moderate hyperthermia and chemotherapy treatment increased the overall therapeutic efficacy by 33.9% (χ2 = 12.182; P < .01).

Abstract
While local hyperthermia application the intratumoral blood flow is enhancing, leading to oxygenation and vascular permeability for antitumoral medicines. The work objective was to investigate the dependence of the development kinetics in carcinoma Gereni (CG) from combined action of doxorubicin (DR) and the kind of thermal impact, a contact one--due to a contact delivery of heat from a water heater and without contact - due to the tumor electromagnetic irradiation (EMI) using heterogenous electromagnetic field (EMF). DR was injected to the animals in a mass concentration of 1,5 mg on 1 kg of their body mass. The DR injection, a contact heating and EMI were started on the 8th day after the tumor reinoculation and kept on conducting once a 2 days. The course had included 5 injections and/or 5 seances of a contact heating and/or EMF. The combined action of DR and EMI, using spatially heterogenous EMF of applicator in environment of physiological hyperthermia, have had influenced mostly the inhibition of a nonlinear dynamics in CG development. Antitumoral action of DR in the animals with CG was influenced by thermal and nonthermal effects, which were initiated by spatially heterogenous EMF. Nonlinear dynamics of a CG development in animals did not depend from horizontal direction of isolines of a spatially heterogenous EMF of inductive applicator towards the tumor and duration of the irradiation procedure (15 or 30 minutes) after DR injection. The data obtained were exploited in clinical practice for the inductothermy optimal regimes elaboration while conducting complex treatment of patients, suffering oncological diseases.

Abstract
Targeting of mechanochemically activated doxorubicin (MA DOXO) nanoparticles, conventional doxorubicin, and electromagnetic irradiation (EMI) at A-549 lung carcinoma cells in vitro was investigated. Conventional DOXO was micronized using an input energy of 20 W/g for 5 min resulting in positively charged MA DOXO particles 10 times smaller than conventional DOXO. Mechanochemical activation gives rise to additional free quinone radicals. High performance liquid chromatograph analyses demonstrate that conventional and MA DOXO are quantitatively similar. Tumor cells were exposed to 40 MHz electromagnetic irradiation at a power density of 2 W/cm2. The lethal dose LD50 values of MA DOXO were 5 times greater than conventional doxorubicin. MA DOXO in combination with EMI at 37 degrees C demonstrates improved drug delivery to A-549 human lung carcinoma and greater cell kill than does conventional DOXO.

Abstract
AIM To examine the effects of electromagnetic field with amplified magnetic component and local inductive hyperthermia (IH) on nonlinear dynamics of the growth of animal tumors. MATERIALS AND METHODS Guerin carcinoma, Lewis lung carcinoma, sarcoma 45, Walker 256 carcinosarcoma and Pliss lymphosarcoma were studied. The animal tumors were exposed inside of loop aerial, 3 cm in diameter locally for 30 min. Parameters of electromagnetic irradiation (EI): frequency 40 MHz, magnetic intensity 72 A/m, electric intensity 200 V/m and the output power 50 W. The temperature measured by immersion of thermocouple inside the center of the tumor didn't exceed 38.5-39.5 degrees C. Nonlinear dynamics of the growth of animal tumors was analyzed by autocatalytic equation. The heterogeneity of ultrasonic image of the tumor was analyzed by Moran spatial autocorrelation. RESULTS The strongest inhibition effect under the influence of EI was in Pliss lymphosarcoma and sarcoma 45. The growth stimulation of animal tumors after EI was recorded in Walker 256 carcinosarcoma. The use of mild IH increased the blood flow in the tumor of Guerin carcinoma. CONCLUSION These results are important for clinical application because they testify the necessity of optimization of schemes for local EI during anticancer neoadjuvant therapy with the use of drugs or magnetic nanoparticles. The use of mild IH as a basis for the monotherapy of malignant tumors is not expedient.

Abstract
AIM To study in vitro influence of mechanochemically activated (MA) doxorubicin (DOXO) and electromagnetic irradiation (EMI) on human lung carcinoma A-549 cells. METHODS Solid state DOXO was MA by input energy 20 W/g during 5 min. Tumor cells were exposed to 40 MHz EMI with power density 2 W/cm(2) at temperature 37 degrees C. RESULTS Particles of MA DOXO have sizes 10 time smaller than officinal DOXO, high performance liquid chromatography analysis showed that parameters of officinal and MA DOXO were quantitatively equal. Mechanochemical activation initiated in the drug formation of free radicals with g = 2.005, g = 2.003 and g = 1.97. LD(50) values of MA DOXO were 5 times lower than that of officinal drug. Cell survival decreased in the following way after effects EMI --> officinal DOXO --> MA DOXO --> officinal DOXO + EMI --> MA DOXO + EMI. CONCLUSION Treatment by MA DOXO and drug with EMI at 37 degrees C showed better targeting of drug in human lung carcinoma A-549 cells outcomes than officinal DOXO.

Abstract
The mechanoemission (ME) of blood is developed as a result of mechanochemical activation of a sample which is layered onto chromatographic paper. This paper describes computer-controlled device, aimed for generation, detection and analysis of ME data in the blood of the persons investigated. The original algorithm for estimation of ME chaos in blood is developed. For gastric cancer patients an increase of ME chaos is observed in comparison with healthy individuals and patients with inflammation of gastric mucosa. The concept of deterministic chaos is biohierarchical for the host of a cancer patient. In the light of this we have calculated that spatial chaos for gastric cancer patients is also increased in the geometrical structure of tumor cells and magnetic resonance imaging of the stomach. The concept of deterministic chaos may find an application in the development of new multi-computer organizations for medical diagnostic equipment.

Abstract
Lymphocyte mechanoluminescence (ML) develops as a result of mechanochemical activation of cells. This paper describes devices (tribogenerators) and techniques for lymphocyte mechanoluminescence analysis. At different stages of the cellular cycle the ML of non-irradiated peripheral blood lymphocytes (PBL) showed characteristic differences. After (60)Co gamma -irradiation of PBL in vitro at 0.25 Gy and 1 Gy an alteration of ML was observed with a relationship between ML values of lymphocytes, and also of mitochondria (MT), and the dose of ionizing radiation used. By using bioluminescence techniques it was shown that gamma-irradiation reduces the amount of ATP synthesized by PBL in the stationary phase.

Abstract
The April 1986 Chernobyl Nuclear Power Plant accident caused ecological changes in the Ovruch State forests in the Zhytomir oblast in the Ukraine. The highest radioactivity existed in moss, followed by the pine-forest substrate and soil. During 1984-1985, the pine needles were primarily surface contaminated, whereas during 1986-1988, they were contaminated secondarily. Radioactivity in air was highest (1.07+/-0.185 Bq/l) during dry and sunny weather and when trees were felled; the lowest levels (0.196+/-0.044 Bq/l) occurred during periods of stable snow coverage. Between 1987 and 1989 (i.e., after the Chernobyl accident), the caesium levels in forestry employees exceeded by 13.9-fold the average levels found in the Ukrainian Polessje population. Ovruch forest guards and woodcutters had the highest effective equivalent doses of radiation, and they therefore exhibited the highest carcinogenic risk.

Abstract
Mechanoemission (ME) of rat peripheral blood lymphocytes (PBL) over the radio-frequency range has characteristic peculiarities in various stages of the cell cycle, both in unirradiated cells and in cells exposed to 0.25 or 1 Gy of gamma radiation. After 52 h incubation of irradiated and unirradiated lymphocytes, ME PBL indices take values equivalent to initial ones in the G0 phase. Increase of radiation dose from 0.25 to 1 Gy was followed by a decrease of the value of the ME PBL kinetic parameter after 24, 40 and maximum 48 h incubation.

Abstract
A comparative study of chemiluminescence and triboluminescence of endothelium of the thoracic aorta in the intact rabbits and in ones with experimental hypercholesterolemia 3, 6, 24 hours after single total influence of low doses of ionizing radiation allowed us to conclude that higher fluctuation of the examined parameters is characteristic feature of the rabbits with hypercholesterolemia. At the same time it was found that the changes in chemiluminescence and triboluminescence of endothelium of the thoracic aorta three hours after irradiation with a dose of 0.25 Gy were different in the experiments in vitro and in vivo.

Abstract
Haemodynamic factors activate mechanochemiemission between the surfaces of vessels and blood cells, i.e. optical, acoustic, heat and radioemissions which initiate formation of lipid peroxide radicals causing vascular wall damage. Subsequent development of mechanochemiemission reactions in lipids results in formation of atherosclerotic plaques in the arterial intima.

Abstract
Mechanic emission is an effect observed in dissipation of mechanical energy due to mechanochemical reactions and electrophysic processes at tension, deformation or friction of blood samples dried on the chromatographic paper. The effect is accompanied by electron emission and electromagnetic radiation. The physical principles of mechanic emission were technically realized while developing and designing a microcomputer approximate analyzer (MPA) for spectral analysis of blood mechanic emission when it was recorded in the optical, electric, and radio channels of information conversion. The arrangement of MPA and analytical methods for its technical parameters are given in the paper. MPA may be useful in supplementary non-invasive differential diagnosis of cancer and inflammatory diseases, as well as in the solution of some diagnostic goals of radiology and cardiology.

Abstract
Accumulation of cholesterol esters and triglycerides in peritoneal mice macrophages in the course of their interaction with lipoproteins of very low density (VLDL) is shown to grow considerably under conditions of hypercholesterolemia. A decrease of triboluminescence intensity characterizing the surface charge has been revealed at hypercholesterolemia both in VLDL and in the blood plasma. It is supposed that the triboluminescence method may be used for testing of the atherosclerotic process development.

Abstract
Triboluminescence (TrL) is optical radiation, arising at the expense of energy of free radical oxidation (in mechanochemical influence) and electrophysical processes in the cell membranes of blood. Under the influence of immunization a decrease of cell membrane polarization is observed. Administration of thymic agents (vilosen and tactivin) into intact and immunized animals decreases the TrL intensity as well, that could be considered as manifestation of their antioxidant effects.

Abstract
The spectrum of triboluminescence by dried blood on a TPA-2 triboluminometer was shown to display four bands of emission with maximum levels at 262, 321, 422 and 649 nm, which are due to the processes of gas discharge in nitrogen and oxygen and to the luminescence of polytetrafluorochlorethylene probe, triboelectriating the samples under study. The intensity of triboluminescence of dried blood and its components depends on the value of pO2 in the liquid phase of the samples.

Abstract
There are variations in the radiation response of lipid peroxidation (LPO) indices. The initial rise of spontaneous chemiluminescence (SCL) immediately after whole-body irradiation (8 Gy) is followed by its rapid drop below the initial level. A considerable increase of the LPO level in the blood, spleen and thymus occurs 24 hr or 2 days after irradiation. The decrease on day 7 is followed by the increase on day 14. The periods of LPO inhibition (15 to 60 min and 7 days after irradiation) correspond to two waves of the hypersecretion of catecholamines and glucocorticoids that have antioxidant activity. With local irradiation of rat skin (a single exposure to 50 Gy) the SCL and malondialdehyde intensity peaks in blood serum are the same as those observed after whole-body irradiation, whereas in the spleen and thymus, these indices regularly decrease. There are peculiarities in the dynamics of triboluminescence in rat blood and organs that is attributed, in addition to LPO, to the effect of radiation on the electric parameters of tissues.

Abstract
On the material of 5 strains of transplanted rat tumours (sarcoma 45, carcinoma Guérin, carcinosarcoma Walker, lymphosarcoma Pliss, erythromyelosis Shvets) and also mice tumours induced by Moloney and Rauscher viruses and on the models of chemical carcinogenesis of rats: lung (intratracheal injection of 3,4-benz(a)pyrene), breast (DMBA) and liver DENA) was shown that tumorous processes of various origin are accompanied by either elevation or inhibition of blood serum spontaneous chemiluminescence (SChL). In all investigated cases the extreme points of SChL curve coincide with the moment of change of tumour growth kinetics.

Abstract
Rat blood triboluminescence resulting from the effect of triboelectrization and activation of free-radical oxidation was studied 15 min to 14 days following gamma-irradiation with doses of 1, 2, 4, 6, 8. and 16 Gy at an original device (triboluminometer TPA-1) in standard conditions of luminescence generation with a contact of the blood sample with a rotating cylinder. Triboluminescence of blood decreased 1-3 days following irradiation and was restored up to the initial level after 7-14 days. Triboluminescence intensity somewhat increased 1-3 days following 1 Gy irradiation.

Abstract
Reliability of biosystems in processes of adaptation and homeostasis after whole-body irradiation of rats with different doses was determined in terms of the stochastic process theory developed for the autoregulatory systems with random parameters. Fluctuations in the rate of spontaneous chemiluminescence of blood serum and accumulation of lipid peroxidation products by erythrocyte membranes of rat blood were taken as the initial material. The analysis of fluctuations of peculiar parameters permitted to predict the adaptability of the system and to make timely corrections.

Abstract
Kinetics of spontaneous chemiluminescence (CL) and electrochemiluminescence (ECL) and resistance of blood serum and its protein, lipid and carbohydrate components under the effect of X-rays (3 to 1622 Gy) and the indirect effect of radiation initiated by the addition of hydrogen peroxide (1.5 X 10(-5)-1.5%) was studied to estimate the contribution of each of the serum components to cumulative changes in the kinetics of free radical oxidation initiated by the effect of radiation. There was a parametric dependence between the absorbed dose, the rate of ECL and the resistance of blood serum and its components. As the absorbed dose or hydrogen peroxide concentration increased ECL contribution to the cumulative luminescence signal regularly decreased. Changes in CL and ECL of blood serum induced by ionizing radiation and H2O2 were qualitatively similar. The kinetics of free radical oxidation of blood serum initiated by irradiation was determined integrally (according to CL and ECL parameters) by a complex of changes in its components.

Abstract
High and low temperatures, physical exercises and acute hypoxia are studied for their effect on indices of peroxide lipid oxidation in highly trained persons under alpine conditions (2100-5600 m). Temperature effects (-15 degrees C and +100 degrees C, for 30 minutes) as well as their combination with acute hypoxy cause an increase (by 10-30%) of malonic dialdehyde and a decrease (by 46-70%) of spontaneous chemoluminescence of blood serum in nonadapted people. Adaptation to alpine conditions in combination with physical exercises and low-caloric diet decreases shifts of these indices, considerably increasing the organism stability to the action of such extreme stress agents as high and low temperatures and acute hypoxy.
