SummaryTympanic plethysmography is a simple non-invasive diagnostic technique which is used to differentiate between intra-temporal carotid aneurysms and glomus jugulare tumours and to predict the degree of extension of the tumour. It is performed by the indirect recording of volume pressure changes of pulsating tympanic masses using a pressure transducer. The volume pressure change of the pulsating mass is transmitted to the pressure transducer through a saline-filled system.Medical technology has undergone considerable progress with the introduction of new techniques in medical diagnosis less harmful to the patient and with a reduced risk of complications. The collaboration of doctors, scientists and bioengineers has resulted in the evolution of such changes, thereby trying to replace the more aggressive or invasive diagnostic techniques. The ideal diagnostic technology is one without pain, harm or complications to the patient.Medical diagnostic technology may be classified as invasive or noninvasive. Non-invasive diagnostic technology is either active, using an external source of energy such as ultrasound (ultrasonography) or a small dose of X-rays, as in computerized axial tomography; or passive, using the energy emitted by human structures, as in plethysmography.Plethysmography is the recording of volume pressure changes. Oculoplethysmography is used to monitor extracranial occlusive carotid disease (Kartchner and McRae, 1973). The use of sound energy as an internal energy emitted by the human body has proved effective as a passive, non-invasive diagnostic technique (Tewfik, 1976, 1977).Volume pressure changes of intra-temporal carotid aneurysms have been recorded, using a pressure transducer (Tewfik, 1974).In this article the volume pressure changes of glomus jugulare tumours have been recorded and the findings compared with those obtained, and previously published, for intra-temporal carotid aneurysms. Volume pressure changes of pulsating tympanic masses may be called tympanic plethysmography. A trial of this simple non-invasive diagnostic technique for differentiating pulsating tympanic masses is here reported, together with an assessment of the technique in its ability to predict the degree of extension of glomus jugulare tumours.

The aim of this study was to observe the influence of electromagnetic radiation (EMR) on the structure and ultrastructure of the rat’s liver. The pregnant rats used in the experiment were exposed to a pulsed microwave radiation (frequency of 2.45 GHz; mean power density of 2.8 mW/cm2) daily for 2 h, throughout their pregnancy. After delivery, the offspring was not exposed to EMR. Samples of the liver of 5-week-old offspring were subjected to histopathological evaluation. They were processed for light and transmission electron microscopy. Our results indicated that EMR did not cause pronounced changes in the structure of the liver of the investigated offspring. The size and shape of liver lobuli was preserved and the amount of connective tissue in the liver parenchyma did not increase. However, electron microscopy revealed changes in the shape and number of microvilli at the vascular pole of hepatocytes, and formation of vesicles of various shapes and sizes. The endothelial cells were swollen with larger fenestrations compared to the control group. The spaces of Disse were irregular and dilated. Even though these changes were only mild, further studies are needed to determine the effect of EMR and clarify its potential risk during pregnancy.

564 Background: Currently endoscopy examination takes an important role in the diagnosis of colorectal cancer, and there are no other clinically viable non-invasive diagnostic methods. In this investigation, a newly developed, novel IVD cancer diagnostic technology named Cancer Differentiation Analysis (CDA) Technology was investigated for colorectal cancer diagnosis. CDA is a new technology using multi-level and multi-parameter information which measures information relating to both protein fragments and cellular signals in blood samples in one single test. Methods: Peripheral blood was drawn in EDTA tubes for CDA tests. Intravenous blood samples from individuals with colorectal cancer (n = 193), as well as control samples (n = 705) were collected. Cancer group has been clinically diagnosed, and individuals in control group have been confirmed by physical examinations free of cancer. All blood samples were tested using a CDA device, and collected data were analyzed in the SPSS Packages. Results: Data analysis (using T test) showed a significant statistical difference with P value < 0.05 between colorectal cancer group and control group. Details of CDA test results were given in Table 1. Based on initial data, the area under curve (AUC), sensitivity and specificity of CDA technology for colorectal cancer were determined to be 0.861, 76.7% and 76.7% (cut-off value was set at a level at which sensitivity and specificity are comparable), respectively. Conclusions: CDA technology is able to statistically distinguish control group from colorectal cancer group with reasonably high sensitivity and specificity (both above 75%). As a non-invasive and potentially cost effective method capable of large population screening, CDA technology could be a very promising approach for the screening and diagnosis of colorectal cancer.

Summary. Diseases of the respiratory organs of children, occurring with obstructive syndrome, represent one of the most serious problems in terms of transition to chronic forms. The chronic process is accompanied by a decrease in pulmonary ventilation, which leads to the search for effective methods of complex therapy of diseases. The purpose of this study was to evaluate the dynamics of acoustic indicators of pulmonary ventilation in children with bronchial asthma, against the background of non-invasive non-thermal microwave radiation. Materials and methods. 122 children with bronchial asthma aged from 3 to 17 years were examined. 113 patients underwent a single session of non-invasive microwave therapy with the Aster device. Comparison of acoustic characteristics of pulmonary ventilation was carried out taking into account the severity of the disease and the age of children with bronchial asthma. Acoustic assessment of ventilation function was performed using the computer bronchophonography complex Pattern-01 before the Aster procedure, after 5 and 15 minutes. In 20 (16.4%) patients with bronchial asthma, the dynamics of cough was evaluated against the background of Aster therapy for 7 days. Results. Improvement of bronchial patency was registered in all age groups with mild bronchial asthma. In the group of moderate asthma, exposure to electromagnetic radiation led to a significant reduction in ventilation disorders in children aged 711 years. As patients grow older, as well as with severe bronchial asthma, the smallest dynamics of the parameters of pulmonary ventilation was observed against the background of Aster therapy. The use of electromagnetic radiation in addition to traditional basic therapy for 7 days leads to a faster regression of cough in patients with bronchial asthma. Conclusion. The combination of traditional basic therapy with electromagnetic non-thermal radiation in patients with bronchial asthma reduces obstructive pulmonary ventilation disorders and promotes faster cough regression.

The problems connected to propagation of a gravitational field are considered. The law of electromagnetic radiation frequency change in gravitational field is shown. The problem of a gravitational field quantization is investigated. Energy of a graviton is found by two ways. First, on the basis of use quantum gravitational eikonal and Lagrangian of a gravitational field the energy of a solitary graviton is found. It is shown that graviton has the mass proportional to its frequency. Second, due to refusal from symmetric stresses tensor in structure of an energy-impulse tensor the quantum form of the energy-impulse tensor in Einstein's equation is found. It has allowed found the energy of a solitary graviton. Both ways of an energy graviton finding has given the identical result. It is shown that the solution of the Einsteins equation with use of the quantum form of an energy-impulse tensor for the certain direction represents the sum of a gravitational wave and a graviton. It is found out that at approach of a graviton to the massive bodies (double stars) radiating gravitational waves there is a resonant pumping of the gravitational field energy of these bodies to the gravitons with increase in their mass and frequency. It enables registration of the gravitons with the help of the detector located near to massive bodies. The assumption is made that dark energy of a gravitational field is all set of the graviton energies of a space.
