Study of the systemic and regional blood pressure in various parts of the maxillofacial area and of microcirculation in tissues and fundus oculi in patients with maxillofacial injuries showed that such traumas involve brain injuries in 100% of cases and are therefore combined. The authors emphasize that this patient population is to be treated for brain injuries.
Morphological study of the hepatic lymph vessels in 16 patients with diseases of the liver and biliary tract and the thoracic duct in individuals of different ages showed that the number and diameter of the lymphatic vessels and the diameter of the thoracic duct increase in the phase of inflammation, Proliferation of connective tissue in cirrhosis reduces the number of lymph vessels, induces valvular incompetence in the thoracic duct attended by ascites. Sixteen patients with diseases of the liver and biliary tract underwent operation for drainage of the thoracic duct. Biochemical parameters and the flow of lymph indicated that the diminished lymph issue is attended on the second day by decrease of the intoxication indices by one third, which is revealed by endotoxin--bile acids, bilirubin, the liver reduces in size and pruritus disappears. The results of the study substantiate the operation for drainage of the thoracic duct and show its importance as a method for the prevention of hepatic insufficiency and for detoxification.
Experimental and clinical substantiation of the use of an original alloyed staple with shape memory allowed it to be recommended for closure of deep wounds of the liver when all other known methods and constructions are ineffective. The staple causes a lesser zone of necrosis than that produced by catgut in closure of a similar wound, and it can be removed with no loss of blood. Consequently, its application is a method of today, causes little injury, and is promising.

Anatomical preparation, Pirogov's saw-cuts and serial histotopographic sections, made across the atlantooccipital and atlantoaxial joints in the sagittal, frontal and horizontal planes in 35 corpses have been used in reconstructing and studying the meniscoid structures in the area of the joints mentioned. The meniscoids are composed of fine fibrillar connective tissue with a large amount of fat and vessels. The meniscoid has a triangle form, its base consisting of collagenous fibers, gradually transfers into the articular capsule, and its apex is directed into the articular cavity. The meniscoid, surrounding the tooth of the axial vertebra, at the sides passes into the medial parts of the atlantoocipital and lateral atlantoaxial joints, forming a single meniscoid complex of the joints studied. A tight connection is stated between the meniscoids and the perineural formations of the I and II cervical nerves and with the vertebral vessels.
The work presents clinico-anatomical grounds of the mechanism of blunt trauma of the kidneys. The variant anatomy of the venous system of the left kidney, adrenals and gonadal veins was studied in 100 adults and children. Morphofunctional investigations were performed in 20 dogs in order to study adrenal functions in left-side nephrectomy. Recommendations for prevention of adrenal insufficiency in left-side nephrectomy are given concerning the level of ligation of the renal vein.

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 left adrenal and ovarian (testicular) ostia are situated at the same level. The distance from the hilus renalis to the place, where the ostia mentioned get into the renal vein, is about 39 mm. In the third variant (19%) the left adrenal vein gets into the left renal vein nearer to the hilus renalis than the ovarian (testicular) veins. An average distance from the hilus renalis to the ostium of the left adrenal vein is 33 mm. 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.
