Cell-mediated immunity (CMI) response to different antigens was examined in healthy women, in patients with cervical precancerous lesions, and in patients with cervical cancer. Cervical lesions were diagnosed by cytological (PAP) smears, from examination by colposcopy, and from “punch” biopsy material by histology. CMI response is related to specific processes in healthy and cancer cells. CMI was investigated by leukocyte adherence inhibition (LAI) assay using specific antigen (prepared from cervical carcinoma tissue) and non specific antigen (prepared from blood of mice infected by LDH—lactate dehydrogenase—virus). The CMI responses of healthy women and cancer patients to the antigens used are different: the majority of T lymphocytes display adherence and non adherence, respectively (but the CMI responses elicited by the antigens are not equal and small quantitative differences are observed). Regardless of the CIN (cervical intraepithelial neoplasia) grades, CMI responses correspond either to healthy women or to cervical carcinoma patients (at about similar ratio of cases in all the CIN groups). Effect of non specific antigen suggests that cervical carcinoma transformation may be connected with reduction of mitochondrial activity similar to processes in LDH virus infection.

Biological systems are hierarchically self-organized complex structures characterized by nonlinear interactions. Biochemical energy is transformed into work of physical forces required for various biological functions. We postulate that energy transduction depends on endogenous electrodynamic fields generated by microtubules. Microtubules and mitochondria colocalize in cells with microtubules providing tracks for mitochondrial movement. Besides energy transformation, mitochondria form a spatially distributed proton charge layer and a resultant strong static electric field, which causes water ordering in the surrounding cytosol. These effects create conditions for generation of coherent electrodynamic field. The metabolic energy transduction pathways are strongly affected in cancers. Mitochondrial dysfunction in cancer cells (Warburg effect) or in fibroblasts associated with cancer cells (reverse Warburg effect) results in decreased or increased power of the generated electromagnetic field, respectively, and shifted and rebuilt frequency spectra. Disturbed electrodynamic interaction forces between cancer and healthy cells may favor local invasion and metastasis. A therapeutic strategy of targeting dysfunctional mitochondria for restoration of their physiological functions makes it possible to switch on the natural apoptotic pathway blocked in cancer transformed cells. Experience with dichloroacetate in cancer treatment and reestablishment of the healthy state may help in the development of novel effective drugs aimed at the mitochondrial function.

Fröhlich electromagnetic radiation from human leukocytes: Implications for leukocyte adherence inhibition test

J. Pokorný; Anna Jandová; Jitka Kobilková; K. Heyberger; T. Hraba

The Fröhlich coherent vibrations may be a source of an electromagnetic field generated by living cells in the frequency range from 0.1 to 10 THz. The electromagnetic field may cause the time dependent orientation (i.e. rotation or rocking) of the polar molecules of the ambient liquid medium and may attract them. The attracted molecules move together with the cell and the friction coefficient of the cellular motion, therefore, may depend on the field. The cell-generated electromagnetic field may interact with the surface charge of various solid-state materials causing attractive forces. These interaction attractive forces may be significant in the process of the leukocyte adherence to the surfaces of various materials. The hypothesis presented in this paper assumes that the exposition of leukocytes from immune individuals to antigen causes changes of the Fröhlich coherent vibrations resulting in decrease of the leukocyte adherence observed in the leukocyte adherence inhibition test.

The leucocyte surface properties manifest the cell-mediated immunity. The response of the cell-mediated immunity to external magnetic field was examined by observing leucocyte adherence to solid state surfaces. In the presence of antigen, leucocytes taken from cancer patients exhibit decreased adherence in contrast with adherence of leucocytes from healthy humans. After 1 h exposure to a sinusoidal magnetic field of 50 Hz and of 1 mT or 10 mT, adherence of leucocytes taken from cancer patients is strongly increased. The 1 mT magnetic field has stronger effect than the 10 mT field.

Abstract Human and animal diseases are brought about by pathological alterations of production, composition, and conformation of macromolecules and structures in cells. Additional contributing factors include changes in physiological states caused by disturbances of energy supply, energy transduction, energy dissipation in moving or oscillating parts, and parasitic energy consumption. Disturbances of energy states may endanger existence of the system. The cell-mediated immunity (CMI) response of T lymphocytes correlating with their adherence properties was examined using antigen prepared from the serum of inbred laboratory mice strain C3H H2k infected with lactate dehydrogenase elevating (LDH) virus. LDH virus is a parasite on the cellular energy system. Significant CMI response was elicited in T lymphocytes prepared from the blood of patients with cancer of different phenotypes, acute myocardial infarctions, schizophrenia, and recurrent spontaneous abortions in early pregnancy from unknown reasons. The CMI response is assumed to monitor transferred information about decreased levels of energy states and decoherence in the cells caused by mitochondrial malfunction, parasitic consumption, production of lactate, and possibly other disturbances. The LDH virus infection or similar pathological processes caused by different agents might be connected with the diseases and monitored by the examined CMI response. A large amount of mitoses with chromosome defects in aborted fetuses suggest increased mutability of genomes caused by defective energy states.

CANCER — PATHOLOGICAL BREAKDOWN OF COHERENT ENERGY STATES

Jiří Pokorný; Jan Pokorný; Jitka Kobilková; Anna Jandová; Jan Vrba

The fundamental property of biological systems is a coherent state far from thermodynamic equilibrium excited and sustained by energy supply. Mitochondria in eukaryotic cells produce energy and form conditions for excitation of oscillations in microtubules. Microtubule polar oscillations generate a coherent state far from thermodynamic equilibrium which makes possible cooperation of cells in the tissue. Mitochondrial dysfunction (the Warburg effect) in cancer development breaks down energy of the coherent state far from thermodynamic equilibrium and excludes the afflicted cell from the ordered multicellular tissue system. Cancer lowering of energy and coherence of the state far from thermodynamic equilibrium is the biggest difference from the healthy cells. Cancer treatment should target mitochondrial dysfunction to restore the coherent state far from thermodynamic equilibrium, apoptotic pathway, and subordination of the cell in the tissue. A vast variety of genetic changes and other disturbances in diffe...

Changes of Leukocyte Adherence Ability Under the Influence of Magnetic Field in the Course of a Treatment of Patients with Laryngeal and Pharyngeal Carcinoma

Aleš Čoček; Ales Hahn; Miloslav Ambruš; A. Dohnalová; Anna Jandová; Jiří Pokorný

The authors were monitoring adherence ability of T lymphocytes in vitro in patients with laryngeal and pharyngeal carcinoma at the presence of tumor=specific and viral LDH antigen. The results were assessed and expressed in percent of non adherent T lymphocytes (NAL). First, NAL in patients before initiating the treatment was compared with NAL control group (voluntary blood donors). The ability of the adherence in T lymphocytes in the control group is statistically significantly higher. Further on, NAL in the course of a successful oncological treatment was monitored at the interval of 6 months folowing the treatment, and further on at yearly intervals. NAL level drops statistically significantly within 6 months and then hold on at levels with no statistical difference unlike the control group, however, the ability of T lymphocyte in patients to adher remains statistically significantly lower. Statistically significantly higher levels of NAL are at the presence of LDH viral antigen. Further on, the authors were following the influence of magnetic sinusoidal field of power frequency (50 Hz) of a low induction (0.5, 0.1, and 0.05 mT) on NAL. NAL values under the influence of an experimental magnetic field before initiating the treatment as well as in the course of a successful oncological treatment are statistically significantly lower. It means that magnetic filed increases the adherence ability of T lymphocytes in patients with laryngeal and pharyngeal cancer in vitro.

STUDY OF THE INTERACTION FORCES IN HUMAN CD4LY

Anna Jandová; Jitka Kobilková; Martina Nedbalová; Jana Šorfová; A. Dohnalová; Stanislav Trojan; Jiří Pokomý

Abstract The cluster formation of CD4Ly cells (a subpopulation of T lymphocytes) in suspension was examined. CD4Ly cells were prepared from blood taken from cancer patients and from healthy counterparts (blood donors). CD4Ly cells taken from cancer patients formed tightly bound clusters in suspension with corresponding tumour antigen or LDH (lactic dehydrogenase) virus antigen. Cluster formation was a rare event in suspensions with CD4Ly cells taken from healthy humans. Cluster formation coincides with decreased adherence of CD4Ly to solid state surfaces and suggests strong mutual interaction between CD4Ly. A tentative theoretical explanation based on the Frohlich coherent vibration hypothesis is given.

Energy parasites trigger oncogene mutation.

Jiří Pokorný; Jan Pokorný; Anna Jandová; Jitka Kobilková; Jan Vrba

Abstract Purpose: Cancer initialization can be explained as a result of parasitic virus energy consumption leading to randomized genome chemical bonding. Materials and methods: Analysis of experimental data on cell-mediated immunity (CMI) containing about 12,000 cases of healthy humans, cancer patients and patients with precancerous cervical lesions disclosed that the specific cancer and the non-specific lactate dehydrogenase-elevating (LDH) virus antigen elicit similar responses. The specific antigen is effective only in cancer type of its origin but the non-specific antigen in all examined cancers. CMI results of CIN patients display both healthy and cancer state. The ribonucleic acid (RNA) of the LDH virus parasitizing on energy reduces the ratio of coherent/random oscillations. Decreased effect of coherent cellular electromagnetic field on bonding electrons in biological macromolecules leads to elevating probability of random genome reactions. Results: Overlapping of wave functions in biological macromolecules depends on energy of the cellular electromagnetic field which supplies energy to bonding electrons for selective chemical bonds. CMI responses of cancer and LDH virus antigens in all examined healthy, precancerous and cancer cases point to energy mechanism in cancer initiation. Conclusions: Dependence of the rate of biochemical reactions on biological electromagnetic field explains yet unknown mechanism of genome mutation.

The Comparison of Methods for Determination of Humoral and Cell-Mediated Immunity in Patients with Breast Cancer

Martina Nedbalová; Stanislav Trojan; A. Dohnalová; Anna Jandová

We observed the immunological answer to antigens obtained from the human malignant breast tumor and from the blood of inbred mice strain C3H/H2K infected by LDH virus. We compared the modified ELISA method for humoral immunity with the leukocyte adherence inhibition (LAI) assay for cell-mediated immnunity. The modified ELISA method is suitable for early diagnosing and monitoring antibodies in a malignant breast tumor simultaneously with senological examinations which include mammography and clinical examinations, because the antibodies are determined in a high number of samples by single application.
