[Activities of the Department of Radiation Diagnosis of the Central Scientific Research Roentgenoradiology Institute].

The main stages in the activities of the scientific units of the Institute since its foundation up to now were represented. The role of Prof. M.I. Nemenov, the founder of the Institute, as a scientist and organizer, and investigations of the staff-members, conducted in different periods, were described. The essence of some researches, carried out at the Institute, was briefly reported.

[Shape of the left ventricular cavity during ejection in patients with ischemic heart disease].

Different types of left-ventricular wall movement were demonstrated in normal subjects and coronary patients, the differences being due to different degrees of reduction in the equatorial diameter of the cavity in the ejection phase. Rationale are given for using the mean diameter for left-ventricular volume calculations. A linear relationship has been demonstrated between the degree of diameter reduction and the ejection fraction. The latter is shown to be dependent on left-ventricular end diastolic volume. Regional myocardial contractility, a parameter of high diagnostic value, based on segmental ejection fraction, is introduced.

[Pharmacolymphography].

With the goal of accelerating the contrast-medium injection at the lymphography and improving the contrasting of the vessels and node conduction system the authors applied a variety of pharmacological preparations: Ridol (G. Richter), Nospanum (Quinoine, HPR), Arfonadum (Hoffman-La Rochet, Switzerland), Xavinum (Quinoine) etc. in 110 cases of various malignant neoplasms. All the selected drugs are, to a greater or lesser extent, of a vasodilative effect. It has been found that Ridol together with the combination of Novocaine and Nospanum produce a pronounced lymphotropic effect. Pharmacolymphography with these preparations contributes to the shortening of the time necessary for the injection of contrast-medium and also improves the image of the intermediate node sinuses and of the thoracic duct.

[Informative value of the indicators obtained during catheterization and ventriculography of the left heart ventricle].

It is found that the main indices determined in catheterization and ventriculography of the left ventricle still provide insufficient information. This is displayed by their considerable variations under normal conditions (conventional normal values). The functional left ventricular volumes vary least in adults; the ejection fraction is most informative. Contraction of the longitudinal axis of the left ventricle and of its transverse diameters and the circular rate of myocardial contraction are most variable. It is necessary to generalize a great scope of material to obtain the normal sex and age values of all indices.
