There are vascular changes in the skin of patients in the combined antihypertensive therapy with β-blockers, vasodilators and indirect anticoagulants. Coagulation and the character of pharmacotherapy directly affect physical parameters of the skin and the formation of rosacea.

The pathogenesis of the arteriosclerosis in the acute myocardial infarction is the matter of the extensive survey with the transmission electron microscopy in experimental and clinical materials. In the previous communication,the authors have clarified that the two types of the coronary vascular changes could exist. The first category is the case in which we had failed to observe no occlusive changes of the coronary vessels which eventually form the myocardial infarction. The next category is the case in which occlusive -thrombotic changes are observed in which the myocardial infarction will be taken placed as the final event. The authors incline to designate the former category as the non-occlusive-non thrombotic lesions. The most important findings in both cases are the “mechanical destruction of the vascular wall and imbibition of the serous component” which are most frequently observed at the proximal portion of the coronary main trunk.

Цель - изучение сывороточных уровней LIF, sLIr и их соотношение с гемодинамическими параметрами (ЧСС, САД, ДАД, ПАД, ЦАД, срАД, УО, МОК, ОПСС, СПВ) и содержанием вазоактивных веществ (AT II, ET-1, NO, ADMA, SDMA, eNOS, iNOS, NT-proСNP, NT-proBNP) у пациентов с эссенциальной артериальной гипертензией (ЭАГ) II стадии. Методы: количество LIF, sLIF-R/gp190 и вазоактивные вещества в сыворотке определяли иммуноферментным методом. Результаты: у пациентов с ЭАГ II стадии вне зависимости от проведения гипотензивной терапии была более высокая концентрация LIF (7,54 (2,8) пг/мл, 7,5 (2,1) пг/мл), по сравнению с условно здоровыми - 1,25 (0,5) пг/мл, р<0,001. При этом у пациентов, не получавших гипотензивные препараты, увеличивался уровень sLIr - (5800 (1470 pg/ml)) по сравнению с больными на фоне гипотензивной терапии (4100 (1380) пг/мл, р<0,001) и условно здоровыми (3800 (1100) пг/мл, р<0,001). При уровне sLIF-R выше 4800 пг/мл обнаруживали связь с увеличением содержания в сыворотке iNOS, NT-proBNP, ADMA, SDMA, (r = 0,5-0,8, р<0,05-0,001) и уменьшением уровня eNOS (r = -0,56-0,86, р<0,05-0,001), что соответствует прогрессированию заболевания. Корреляции между LIF и указанными вазоактивными веществами выявлено не было, что дает основание предполагать, что sLIFr вызывает собственные патогенетические эффекты помимо антагонистической активности по отношению к LIF. Aim. To study levels of serum LIF and sLIF-R and their correlations with hemodynamic parameters (heart rate, systolic BP, diastolic BP, pulse pressure, central BP, mean BP, stroke volume, total peripheral resistance, and pulse wave velocity) and vasoactive substances (AT II, ET-1, NO, ADMA, SDMA, eNOS, iNOS, NT-proСNP, and NT-proBNP) in patients with stage II essential arterial hypertension (EAH). Methods. Serum levels of LIF and sLIF-R/gp190 were measured using ELISA in 180 patients with stage II ЕAН. Results: Patients with EAH II (with or without antihypertensive therapy) had higher serum levels of LIF (7.54 (2.8) pg/ml and 7.5 (2.1) pg/ml, respectively) compared to healthy individuals (1.25 (0.5) pg/ml), р<0.001. Patients not receiving a therapy had higher serum levels of sLIF-R (5800 (1470 pg/ml) than patients receiving antihypertensive drugs (4100 (1380) pg/ml, р<0.001) and healthy individual (3800 (1100) pg/ml, р<0.001). In patients with EAH, sLIF-R levels higher than 4800 pg/ml correlated with increases in iNOS, NT-proBNP, ADMA, and SDMA (r = 0.5-0.8, р<0.05-0.001) and decreases in eNOS (r = -0.56-0.86, р<0.05-0.001), which corresponded to disease progression. LIF did not show any significant correlations with these vasoactive substances, which suggested that sLIF-R exerted its own pathogenetic effects besides antagonizing LIF. Generally, this trend was typical for patients with EAH (II stage) without antihypertensive therapy.
