[Compensatory role of the external carotid artery in vascularization and revascularization of the brain following occlusion of the homolateral internal carotid artery].

An examination of 33 patients with internal carotid occlusion showed that this was a group of grave patients who had suffered an ischemic stroke with the lesion localization in the basin of the carotids. By using additional examination methods it has been found that it is also the homolateral external carotid which performs (along with the contralateral internal carotid) the principal compensatory function in the revascularization of the stroke-affected hemisphere. In patients with the internal carotid occlusion complicated by a stenosis of the external and an affection of the general carotids, sparing operations of applying a vascular prosthesis connecting the subclavicular and external carotid arteries were performed.

[Myocardial hypertrophy in stenosing arteriosclerosis of the abdominal aorta].

In 57 patients with stenosis or occlusion of the terminal segment of abdominal aorta the authors measured the myocardial mass and the end diastolic volume of the left ventricle before the operation and 15-20 days after it (shunting or prosthesis of bifurcation of the abdominal aorta). Prior to operation increase of the myocardial mass of the left ventricle was found in 77.2% of patients.

[Collateral circulation syndromes in the brachiocephalic artery system].

In 56 patients qualitative and quantitative characteristics of variants of collateral circulation in the system of occluded brachiocephalic arteries were studied. The objects of the studies were angiographic and clinical appearance of the variants of retrograde blood flow and the latter's connection with cerebral circulation. It was shown that the reversion of the blood flow from the Willis circle system was observed in 25% of patients with occlusive affections of the brachiocephalic arteries.

[Effect of retinol and alpha-tocopherol on the stability of phosphatidylcholine bilayer membranes].

The modifying action of retinol and alpha-tocopherol on the stability of bilayer phosphatidyl choline membranes was studied under control of their oxidation. The membranous stability was determined by the time during which the value of the ionic conduction of the membrane in a stationary condition remained unchanged. It was shown that the stability of the membranes modified by the addition of retinol and alpha-tocopherol was not a monotonous function of the modifier concentration in the membrane (but it was achieved through maximum).

[Morphology of fibromuscular dysplasia of the renal arteries].

Fibromuscular dysplasis of the renal arteries was revealed in 35 patients with renovascular hypertension. Histological examination revealed the following forms of this lesion: fibroplasia of the intima, hyperplasia and fibroplasia of the media, subadventitial fibrosis, as well as their combination. It was found that not only the main branch of the renal artery but also the small intrarenal branches are affected.

[Principles of the surgical treatment of combined lesions of the brachiocephalic and renal arteries in nonspecific aorto-arteritis].

The presented work is founded on the analysis of the results of the surgical treatment of 43 patients with combined injuries to the brachycephalic and renal arteries, manifested clinically as syndromes of cerebral ischemia and vasorenal hypertension. 50 operations were carried out upon 43 patients. 45 of these 50 operations were reconstructive ones.

[Soluble milk protein concentrates, casecites, for infant and dietetic nutrition].

A soluble form of caseins, so-called casecites for an infant and dietetic nutrition, is obtained from separated milk by way of solving casein through using freshly precipitated lactic acid terment of 0.1 n HCl, mixed with solts-solvents. The lactoproteinic concentrates-casecites have an elevated biological value, called forth by the content of large amounts (80.

[Method of determining and the makeup of the aliphatic hydrocarbon fractions of sunflower, cottonseed and soya oils and of oil cakes].

To determine the content and composition of aliphatic carbohydrates in vegetable oils and oil cakes a method including alkaline hydrolysis, partition and thin-lower chromatography, gas-liquid chromatography and chromate-mass-spectrometry was devised. The content of n-isoalkans, isoprenoids, monocycloparaffins, bi-and tricyclic naphthenes, steranes and terpenes, olifines, squalene and other polyenes in sunflower, cotton, soya oils and oilcakes was measured.

[Effect of tocopherol and protein deficiency on the activity of enzymes and their isoenzymatic spectra in rat testes].

The symptoms of E-avitaminosis against protein deficiency in the ration become manifest much earlier, i. e. in 12--16 weeks of the experiment instead of 24--36 weeks with the primary-deficient ration.
