Antibacterial Mode of Action of the Essential Oil Active Compounds against and Efflux-Mediated Drug Resistance in Gram-Negative Bacteria.

Today, an alarming rise of bacterial gastroenteritis in humans resulting from consuming -tainted foods is being observed. One of the solutions for mitigating this issue may be the antibacterial activity of essential oils. In the present research, we propose to study the antibacterial activity against and other Gram-negative bacteria of essential oil and its active molecules.

[Theoretical substantiation and experience in vibromechanical dilatation of hollow organs].

The paper analyzes the principle of operation of a dilatation catheter, a device designed for expanding hollow organs. The organs (blood vessels, esophagus, cervix uteri through the cervical canal, uterine tubes) were the subject of investigation. The effective energy of action on the hollow organ wall in different catheter operations and the safety index for dilatation of hollow organs were defined.

[Hemodynamics and load tolerance in pregnant women with mitral heart defects].

Changes in the hemodynamic parameters under conditions of physical load on a bicycle ergometer were studied in 107 pregnant women among whom 73 had mitral valvular disease and 34 did not have a somatic disease. Three groups of tolerance to physical load and the criteria of an adequate or inadequate reaction to it were determined. This method of examination of the reserve potentialities of the heart reveals the preclinical stage of cardiac insufficiency and borderline conditions, owing to which the most rational predelivery therapy and the method of delivery may be chosen in advance.

[Use of the bicycle ergometric test in the differential diagnosis of climacteric cardiopathy].

Bicycle ergometry on the "Elema" electrical bicycle ergometer was conducted on 6, patients of climacteric age (41 to 55 years) with pain in the region of the heart and ECG changes. The method made it possible to confirm the diagnosis of climacteric cardiopathy in 39 and to reveal climacteric cardiopathy and concurrent ischemic heart disease in 23 patients. It was noted that physical load had a favourable effect on processes of repolarization in the myocardium of patients with climacteric cardiopathy.

[Characteristics of the course of pregnancy in women with heart defects].

In 33 patients with different forms of the cardiac valves lesion the specificity marking the course of atriomegalia was studied on the ground of clinical, roentgenological and functional findings. Unlike non-pregnant women with similar forms of the malady here intercurrent pulmonary hypertension during gestation was ascertained, this increasing the hazard of developing edema of the lungs. The authors give preference to delivery in these patients via natural maternal passages by employing the operation with application of obstetrical forceps.
