[Possibilities of general x-ray studies in the diagnosis of wounds of the diaphragm].

To define the value and potentialities of general X-ray study in the diagnosis of diaphragmatic wounds, the X-ray findings were analyzed in 124 victims with punchred and incised wounds of and in 15 patients with gunshot ones of the diaphragm. The paper outlines X-ray procedure and roentgenological signs of damages to the diaphragm in its single and combined injury. Four groups of victims in whom the frequency and magnitude of X-ray changes were related to the predominant wound of either organs of the chest or abdomen were identified.

[Effect of long-term ambulatory hypotensive treatment on the structural and functional status of the myocardium].

Changes in myocardial function and the possibility of a regression of left-ventricular hypertrophy were examined in patients with stable hypertension during a year of effective hypotensive treatment. Ninety-seven patients with essential hypertension, stage IIB (by Myasnikov's classification) and aged 35 to 56 years, were studied. Echography was conducted before the onset of treatment and after one year of regular hypotensive therapy.

[Characteristics of left ventricular hypertrophy in patients with different forms of arterial hypertension based on echocardiographic data].

Echocardiographic investigation of 110 patients with different forms of stable arterial hypertension demonstrated a moderately close correlation between left-ventricular myocardial weight, and systolic and diastolic arterial blood pressure in patients with essential hypertension and chronic diffuse glomerulonephritis, and a weak correlation between left-ventricular myocardial weight and systolic pressure in patients with renovascular hypertension and chronic unilateral or predominantly unilateral pyelonephritis. Inadequate left-ventricular hypertrophy has similar incidence (15-20%) in patients with different forms of arterial hypertension, whereas excessive hypertrophy only occurs in patients with essential hypertension. The frequency of asymmetrical hypertrophy differs in the two groups.

[Effect of physical load adaptation on the age-related dynamics of the contractile function and weight of the human left ventricle].

Echocardiographic investigation of the mass and function of the left ventricle was undertaken on 110 trained to endurance and 100 nontrained young individuals 10 to 30 years of age. It is established that in the nontrained group aged from 10--12 up to 20--30 the mass of the left ventricle increases approximately by 50 g, which is over 70%. Correspondingly the end diastolic volume of the ventricle rises by 50 ml i.
