[Changes in human cerebral cortex in various areas of concussion in severe cranio-cerebral injury].
In 23 patients with a severe cranial-cerebral trauma the operative material (pieces of the cortex, obtained from the destructive, transitional and relatively preserved zones in the bruise foci with crushing, localized in various lobules of the cerebral hemispheres) has been studied. From 2 h up to 9 days after trauma, changes, characterizing the state of the vascular bed, nervous and glial cells have been followed. ⋯ Only in the destructive zone in all 23 patients and in the whole transitional zone in 8 patients neurons in all cortical layers are deeply injured and unviable. Certain considerations on differential surgical tactics, when treating the bruise foci with crushing at a severe cranial and cerebral trauma are presented.

[Functional significance of the left adrenal vein and the gonadal veins].
Owing to the investigation of changeability variants of the left adrenal, anastomosis of the inferior diaphragmatic and ovarian (testicular) veins--tributaries of the human left renal vein, three variants in inflow of the left adrenal vein in comparison to the left ovarian (testicular) vein have been revealed. In the first variant, that occurs in 70% of cases, the left adrenal vein flows into the left renal vein by 15 cm more medially from the ostium of the ovarial (testicular) vein. The second variant occurs in 11%. ⋯ The second variant, when the left adrenal vein gets into the left renal vein, contributes to appearance of the primary varicocele at the left. When the operation for nephrectomy is made at the left, our data make it possible to recommend a purposeful ligation of the left renal vein more laterally to the ostium of the ovarian (testicular) vein. In 80% this ligation will not disturb the function of the left adrenal vein.
