[Infrared irradiation of the anterior abdominal wall in pathology of the gastroduodenal area (mechanisms of formation of the radiation foci and clinical evaluation)].

The data obtained during endoscopy, thermography electromyography, myotonometry and electroalgesimetry were compared in patients with gastroduodenal pathology. It was established that in patients with peptic ulcer, the times of the appearance of the foci of intense infrared radiation in the projection areas did not coincide completely with the period of ulcerous defect revelation by means of endoscopy and indicated the phases of the disease activity more precisely. The foci of intense infrared radiation agreed with the zones of protective muscular tension. Since as a result of muscular contraction the skin temperature above the muscles rises, the data obtained should be taken into account in the design of the theory of thermography. The complex of the studies proposed is conducive to an objective differential diagnosis and to better results in the observation over patients suffering from gastroduodenal diseases.

[The differential diagnosis of various forms of hypertrophic cardiomyopathy and hypertension with inadequate left ventricular hypertrophy].

In order to develop the tentative criteria of the differential diagnosis, 18 patients with obstructive hypertrophic cardiomyopathy (OHCMP), 3 with nonobstructive hypertrophic cardiomyopathy (NOHCMP), 8 with essential hypertension (EH) with inadequate left ventricular hypertrophy (LVH) and 10 normal persons were subjected to clinical examination and to ultracardiosonography. The patients with OHCMP mainly complained of dizziness and syncopes. Since childhood they had systolic murmur and ECG abnormalities. Ultracardiosonography showed asymmetrical LVH, a considerable decrease of the ventricular cavity as well as abnormalities of the localization and function of the papillary muscles. NOHCMP was marked by the combination of the good well-being of the patients with gross abnormalities on the ECG. Ultracardiosonography demonstrated moderately pronounced and asymmetrical LVH. The group suffering from EH with inadequate LVH was characterized by the early development of severe circulatory failure with arterial hypertension of moderate intensity. The changes in the architectonics of the left ventricle and its subvalvular structures turned out to be similar to those in OHCMP but were less remarkable.

[Characteristics of cardiac structure and function in young persons with so-called functional murmurs (clinical echocardiographic research)].

As many as 70 males aged 14 to 28 years with functional systolic murmur and 16 young persons of the same age, in whom murmur failed to be detected both at rest and after 15 squattings and the hyperventilation test. It was shown by echocardiography that in addition to the proneness to the hyperdynamic type hemodynamics, the patients with functional murmurs manifested, in different anatomicofunctional heart zones, definite characteristics of the heart structure which in the majority of the examined (77.1%) were marked by deformity of the left ventricular contours. Therefore, the left ventricular chamber is the main area where in young persons there occurs functional systolic murmur. Frequent combination with each other of heart structure characteristics in persons with functional systolic murmur attests to the diversity of the causes and mechanisms by which it forms.

[Fungus invasion in the morphogenesis of gastro-duodenal ulcers].

The goal of the study was the clarification of the role of the fungus Candida in the course of the ulcer. The combination of morphological, cultural and immunological methods was used for the diagnosis of the fungus involvement. Inhibition of the reparative processes by the fungus Candida was shown in the experiment on the model of the chronic gastric ulcer. It is concluded that in patients with chronic ulcers histological examination of the biopsies for fungi should be performed.
