Involvement of the different extracts from roots of Salvia miltiorrhiza Bunge on acute hypobaric hypoxia-induced cardiovascular effects in rats--preliminary report.

The present study was carried out to investigate the protective effects of roots of Salvia miltiorrhiza Bunge on hypobaric hypoxia. Two extracts of S. miltiorrhiza (extract 1: ethanol : water - 50 : 50; extract 2: 96% ethanol) were used.

The relationship between concentrations of magnesium and oxidized low density lipoprotein and the activity of platelet activating factor acetylhydrolase in the serum of patients with type 1 diabetes.

The study was aimed at comparing the concentration of metabolic parameters, the serum concentration of oxidized low density lipoproteins (oxLDL) and the activity of platelet activating factor acetylhydrolase (PAF-AH) in the relation to the serum concentration of magnesium (Mg) in patients with type 1 diabetes (DM1). DM1 patients (n=78) were divided into 2 groups: patients with low serum Mg concentration (<0.7 mmol/L, group 1, n=34) and patients with reference levels of Mg (>or=0.

The evaluation of IL-12 concentration, PAF-AH, and PLA(2) activity in patients with type 1 diabetes treated with intensive insulin therapy.

Objectives: The aim of the study was to evaluate the concentration of interleukin 12 (IL-12), the activity of phospholipase A(2) (PLA(2)), and platelet-activating factor acetylhydrolase (PAF-AH) in type 1 diabetes (DM1) patients treated with intensive insulin therapy.

Design And Methods: Studied parameters were measured in 81 patients, who were subdivided according to the HbA(1)c value, hsCRP concentration, and presence or absence of late complications.

Results: PAF-AH activity was higher in the DM1 patients versus the control group (P=0.

Acamprosate involvement in triacylglycerol hydrolysis and transacylation with cholesterol in chronically ethanol-drinking rats.

Acamprosate (AC) is used as a drug for treating alcoholism. We evaluated the effect of AC on serum triacylglycerol hydrolysis (GEH, glycerol ester hydrolysis), triacylglycerol transacylation with cholesterol (GECAT, glycerol ester:cholesterol acyltransferase), and acylcholesterol hydrolysis (Cease, cholesterol ester hydrolysis) in an experimental model of alcoholism. Ethanol-preferring (PRF), non-preferring (NPF), and control (CR) male Wistar rats were treated with AC (500 mg/kg, p.

Effect of simvastatin on trioleylglycerol hydrolysis and transacylation with cholesterol in serum of outpatients with coronary heart disease.

At present, the most effective drugs in treating hypercholesterolemia and atherosclerosis are the statins, which are potent inhibitors of the rate-limiting enzyme 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase. Serum triacylglycerol (TAG) levels associate positively with the risk for coronary heart disease (CHD). Triacylglycerols are mainly hydrolyzed by the enzyme lipase (glycerol ester hydrolase [GEH], EC 3.

The influence of simvastatin on lipase and cholesterol esterase activity in the serum of men with coronary heart disease.

Several studies have demonstrated that any beneficial effects of 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors (statins), of which simvastatin (Merck Sharp & Dohme) is an example, on coronary events are linked to their hypocholesterolemic properties. The in vivo effects of simvastatin treatment on lipase (GEH = glycerol ester hydrolase) and cholesterol esterase (CEase) activity in the serum of men with coronary heart disease (CHD) were examined. GEH and CEase activity in the serum of men with CHD, before simvastatin treatment, was lower than in the control subjects.
