Endothelin-1 (ET-1) has been implicated in many cardiovascular diseases, including acute heart failure (AHF) due to myocardial ischemia. Previously we described the oral endothelin-converting enzyme (ECE) inhibitor, PP36, and in this study, we investigated its cardioprotective effect in more detail, and examined the role of PP36 in the neurohormonal(More)
The VerifyNow assay is based upon the ability of activated platelets to cross-link beads coated with fibrinogen. However, fibrinogen is an abundant protein of blood, and therefore it may affect test results by competing with fibrinogen of beads for binding to platelets. To test this assumption, we assessed the influence of artificial alteration of(More)
The protein C activator detectable in the venom of the Southern Copperhead snake (Agkistrodon contortrix contortrix) was isolated by a combination of chromatofocusing on PBE-94 in the range pH9-7 and gel-filtration on Sephadex G-100 column. The peak protein C activator from Sephadex G-100 column appeared as double diffuse bands with apparent molecular(More)
The activity of tissue plasminogen activator (TPA), its rapid inhibitor (TPAL), C protein (Cp), plasminogen, alpha 2-antiplasmin, antithrombin III was evaluated and the levels of fibrinogen-fibrin degradation products and fibrinogen (F) were measured in 51 males with persistent coronary heart disease (CHD) and 16 without coronary atherosclerosis and(More)
Activated C protein (ACP) is a physiological anticoagulant enzyme that is capable to inactivate factors Va and VIIIa, thereby having a wide spectrum of antithrombotic effects. Low-dose ACP was tested for its ability to affect anodic current-induced arterial thrombosis in the rat. ACP given in low doses (15 micrograms/kg, 7% of total C protein in the rat)(More)
We studied action of a nitric oxide donor, dinitrosyl complex of iron (DNIC) with glutathione as a ligand on the hemodynamics of normotensive Wistar rats, spontaneously hypertensive rats (SHR), and monkeys. Intravenous DNIC introduction (2-120 mg/kg) rendered fast (1-2 min) hypotensive effect combined with increased heart rate by 10-25%. Second phase of the(More)
To study complex of pathogenetic changes arising during VVI mode single chamber ventricular pacing we temporarily (for 1 hour) switched pacing mode from dual (DDD) to single (VVI) chamber stimulation in 11 patients. Parameters studied were cardiac output (CO), total peripheral vascular resistance (TPVR), levels of precursors of atrial and inactive fragment(More)
The levels of plasminogen activator inhibitor (PAI), protein C (pC), total cholesterol (TC), high and low density lipoprotein cholesterols (HDLC and LDLC), apolipoproteins A1 (apoA1) and B (apoB) were measured in 45 patients with coronary heart disease angiographically documented and 10 healthy subjects without coronary heart disease and coronary(More)
Elevated levels of fibrin peptide A were found in venous occlusion only in the patients unconsuming C protein, which indicates that there is a relationship between the thrombin production processes during venous occlusion and the C protein system functioning, the anticoagulant function of the endothelium in particular. Moreover, this makes it possible to(More)
The authors examined the activities of plasminogen activator, its inhibitor, the levels of C protein, antithrombin III, alpha 2-antiplasmin, plasminogen, fibrinogen, fibrinogen/fibrin degradation products in 22 patients with unstable angina by using the vein occlusive test. No significant differences were found in the examined parameters while comparing the(More)
