Expression of tissue factor (TF) by activated monocytes may initiate thrombotic episodes associated with diseases, such as thrombosis and atherosclerosis. In this study, steps in the regulatory pathways of lipopolysaccharide (LPS)-induced monocyte TF activity and released TNF-alpha in human whole blood were probed for using an array of inhibitors, comprising specific inhibitors of cytosolic phospholipase A(2) (PLA(2)) (AACOCF(3)), secretory PLA(2) (SB-203347), protein kinase (PK) (staurosporine), PKC (GF-109203; BIM), and serine protease (Pefabloc SC), antagonists of thromboxane prostanoid (TP) receptor (R) (SQ-29548), platelet activating factor (PAF) R (BN-52021), leukotriene B(4) R (SC-41930), serotonin R (cyproheptadine), fibronectin/fibrinogen R (RGDS), and finally, creatine phosphate/creatine phosphokinase (CP/CPK) which removes ADP. Whereas when added alone neither of these agents significantly inhibited LPS-induced TF or TNF-alpha, when presented as a reference cocktail comprising all the agents, TF activity and TNF-alpha were reduced by 77% and 49%, respectively. By subsequently testing a series of incomplete inhibitory cocktails equal to the reference except for deleted single agents or combinations of two or three active agents, the inhibitory effect of the reference cocktail could be shown to depend on the presence of the protease inhibitor and the thromboxane A(2) and PAF antagonists.

Nephrotic dyslipidemia is a risk factor for the development of systemic atherosclerosis, and may aggravate glomerulosclerosis and enhance progression of glomerular disease. The greatest and most consistent reductions in LDL-cholesterol are achieved with HMG-CoA reductase inhibitors but their efficacy and safety in long-term therapy need to be evaluated. In this study, we gave fluvastatin to 21 nephrotic patients and followed then up clinically, neurophysiologically and by laboratory tests. There was an improvement in the lipogram, with reductions of triglycerides (TG) (33%) and LDL (35%) at three months. There was no clinical manifestation of myopathy and CPK was normal. Electromyographic data showed significant decreases in the amplitude and duration of motor unit action potentials in the proximal muscles with statin therapy, but these changes did not amount to classic myopathy. We conclude that fluvastatin is a safe drug for long-term use in dyslipidemic nephrotic patients. However, we suggest further studies to verify whether the early electromyography (EMG) changes observed in this study may progress or not on its longer term use.

Epidemiological studies have shown that there is a positive correlation between the incidence of coronary heart disease (CHD) and the blood cholesterol level. To study the effect of plant derived triterpene, lupeol and its ester lupeol linoleate, on blood lipid status and oxidant stress in heart and hemolysate, male albino Wistar rats were fed high cholesterol diet (normal rat chow supplemented with 4% cholesterol and 1% cholic acid; HCD) for 30 days. A significant increase (p<0.05) in plasma total cholesterol (4.22 fold) and triglycerides (1.7 fold) was observed in HCD fed rats, along with elevated LDL (3.56 fold) and VLDL (1.99 fold) cholesterol and decreased HDL cholesterol (34.14%). Treatment with lupeol and its derivative normalized the lipid profile. The significant increase (p<0.05) in lipid peroxidation (LPO) was paralleled by significantly diminished (p<0.05) activities of antioxidant enzymes (SOD, CAT and GPx) and decreased (p<0.05) concentration of antioxidant molecules (GSH, Vit C and Vit E) in cardiac tissue and hemolysate of HCD fed rats. The oxidative tissue injury in hypercholesterolemic rats was substantiated by the increase in cardiac marker, serum CPK and the drop in its activity in the heart tissue. Lupeol and lupeol linoleate treatment decreased the LPO levels and increased enzymatic and nonenzymatic antioxidants. CPK activity in the treated group was comparable with that of the control. These observations highlight the beneficial effects of the triterpene, lupeol and its linoleate ester derivative, in ameliorating the lipidemic-oxidative abnormalities in the early stage of hypercholesterolemic atherosclerosis.

The study ob]ective was assessment of pathogenetic and prognostic significance of gynecologic and obstetrical pathology and the concentrations of sex steroids in adult women with acute coronaty syndrome (ACS). The study group included 120 postmenopausal women with ACS treated in the Clinic of Cardiology, University Hospital "Alexandrovska" between 2011 and 2013. Sex hormones were measured in 57 patients. Enzyme, electrochemiluminescent, enzyme-linked immunologic and immunoturbodimeric methods were used for the examined indices assessment. The history for gynecologic disorders and pregnancy complications was associated with coronaiy atherosclerotic burden (SYNTAX score - 4,6+/-8,8 vs 8,5+/-9,3, p=0,003), gynecologic history only - with lower 17Beta-estradiol levels (139,01+/-167,66 vs 113,51+/-304,1, p=0,004) and coronaly atherosclerosis severity (5,5+/-9,3 vs 8,0+/-10,3, p=0,058). Abnormally high endogenous concentrations of androgens were found among the patients with ACS with ST elevation, STEMI (27,5% vs 77,8%, p=0,004), with significantly more intense acute infiammatoty response (8,7+/-3,21 vs 11,07+/-2,85, p=0,044 3a WBC) and more extensive acute myocardial damage (57,8+/-12,6 vs 45,3 ml, p=O,OO8 for e]ection fraction 33,7+/-37,4 vs 117+/-144,22 U/L, p=0,031 for CPK-MB; 0,89+/-8 18 vs 1,87+/-0,4 ng/ml, p=0,009 for hsTnT). The gynecologic and obstetrical history and hyperandrogenism are related to the extent and severity of coronary atherosclerosis, occurrence of STEMI, more intense acute inflammatory response and myocardial injury among postmenopausal women with ACS.
