[Method for determining leukocytic lipid-releasing capacity in the diagnosis of mechanisms responsible for atherogenesis in patients with coronary heart disease and ischemic stroke].

The authors have studied the mechanism responsible for neutrophilic accumulation and release of protein-lipid complexes in patients with atherosclerosis and the clinical value of this reaction. They present the results of experimental studies and clinical observations in the groups of patients with ischemic stroke, coronary heart disease, bronchial asthma, chronic obstructive pulmonary disease, and rheumatoid arthritis. Whether the process of neutrophilic and release of protein-lipid can be in vitro modulated in a 3-day culture has been demonstrated. The high diagnostic value of the method for determining the lipid-releasing capacity of leukocytes is shown. Some proteins involving in the formation of pathogenic protein-lipid complexes are identified. There is evidence for the use of new differential criteria for visceral diseases originating from atherosclerosis.

[Leucocytes' ability to accumulate and secrete cholesterol is a nonspecific factor of immune inflammation in patients with atherothrombotic stroke].

The aim of the study was investigation of nonspecific inflammation markers in atherosclerotic injury of major arteries of the head (MAH). A complex study, including duplex ultrasonography, CT, measurement of cholesterol and its fractions, has been conducted in 85 patients with atherothrombotic (72 patients) and lacunar (23 patients) stroke. The ability of leucocytes' culture to accumulate and secrete cholesterol in vitro was studied as a nonspecific inflammatory marker of lesion of atherosclerotic MAH. A high level of this index was characteristic of atherothrombotic type of stroke comparing to lacunar stroke and the control group. Furthermore, high levels of this index correlated with severity of atherosclerotic injury of MAH, in particular with plaques. The dynamics of the index after 24-day therapy by statins (vasilip) is presented. We suppose that the protective influence of statins in patients after ischemic stroke may be caused by the effects on the level of immune competent cells including reducing leucocytes ability to accumulate and secrete protein-lipid complexes.

[Endothelium dysfunction in patients with ischemic stroke].

A vasomotor endothelial function has been studied in 57 patients with ischemic stroke using ultrasound by the reaction of the brachial artery to reactive hyperemia. The duplex scanning of brachyocephalic arteries was conducted. Twenty-four patients had impaired endothelial-dependent vasodilatation. Endothelial dysfunction was associated with cholesterol blood level and smoking. Aging, positive family history and arterial hypertension did not affect this parameter. A level of vasomotor dysfunction correlated with intima-media correlation, the presence of plaques in the carotid arteries and internal carotid artery occlusion. Impaired endothelial-dependent vascular relaxation occurred more frequently in atherothrombotic than in lacunar stroke and in patients with a severe brain damage.
