[The formation of the School of Military Neurosurgery of the Military Medical Academy].

The article is devoted to stages of formation of the school of military neurosurgery. Famous pioneers of this school were Vsevolod Galkin and Boris Samotokin. Their scientific works were based on personal experience of treatment for the battle scull and brain injuries during the Great Patriotic War.

[Change in the width of the preischemic and late myocardial zones].

A new approach to the determination of the boundaries of the preischemic zone and zones compensating for the focal disorders of the contractile activity of the hepart is described. During 30 minutes of inschemia, the width, localization, and intensity of functioning of the borderline and compensation zones changed. On the 15th minute of disturbed coronary blood flow the compensation zone was widest.

[Presystolic change in the length of the ischemic, border and distant myocardial areas in experimental coronary insufficiency and the action of inderal and metacin].

Changes in the presystolic length in the phase of late diastole and in the size of active shortening in the phase of ejection were determined in the ischemic area and in areas of the myocardium bordering upon and in those remote from the focus of ischemia in acute experiments on the 20th and 60th seconds of reversible clamping of the coronary artery. Marked increase in the presystolic length and size of active shortening of the remote areas was noted by the 20th second. In the ischemic zone these values decreased.

[Comparison of the blood plasma depressor prostaglandin content and the indicators of hemodynamics in dogs with experimental myocardial infarct and cardiogenic shock].

The quantitative composition of depressor prostaglandins PGE1 and PGA1 in the plasma of arterial and venous blood and blood from the great cardiac vein was studied in comparison with the values of hemodynamics in dogs with experimental myocardial infarction and cardiogenic shock. The content of prostaglandins in blood plasma was determined by the radioimmune method. The development of acute coronary insufficiency was attended with changes in the quantitative composition of the depressor PGE1 and PGA1 in the plasma of arterial and venous blood and blood from the great cardiac vein.
