[Results of dynamic assessment of melatonin receptor expression in lymphocytes in patients with acute mild and severe pancreatitis].

The authors present results of the investigation of melatonin receptors expression in lymphocytes in dynamics in 102 patients with acute pancreatitis of mild and severe form and in 50 volunteers. A correlated analysis was made between obtained results of laboratory and instrumental researches and clinical course of acute pancreatitis. The decrease of MT1 receptors expression was noted on 25% in patients with acute pancreatitis.

[Determination of melatonin receptors in human blood mononuclear cells: clinical and experimental rationale].

Melatonin is a mammalian hormone that has a great variety of effects. At present there is evidence that this hormone considerably reduces the manifestations of many gastrointestinal inflammatory diseases. The biological effects of melatonin are realized through the receptors located on the membranes of different animal cells.

[Activity of chymotrypsin-like proteinases in patients with ischemic heart disease, arterial hypertension and nonspecific aortic arteritis].

Aim: To analyze activity of chymotrypsin-like plasma proteinases (CTP) in patients with various cardiovascular diseases.

Material And Methods: CTP activity was studied in 82 patients with various cardiovascular diseases: 13 coronary heart disease patients with normal arterial pressure, 49 patients with essential hypertension (EH) and secondary arterial hypertension, 20 patients with nonspecific aortic arteritis. 28 donors served control.

[Left ventricular function in patients with arterial hypertension during the performance of acute drug tests with captopril and nifedipine].

An examination was made of 22 hypertensive patients with clinical and echoCG symptoms of left ventricular hypertrophy. All the patients underwent coronary angiography, transvenous multiphase left ventriculography and acute captopril (11 patients), nifedipine (11 patients) tests. A single oral 25 mg dose of captopril increased energetic efficacy of cardiocycle, restored diastolic function of the left ventricle, aroused myocardial contractility.
