BACKGROUND AND PURPOSE Arterial remodeling may enable atherosclerotic disease without luminal stenosis. We sought to assess the prevalence and characteristics of atherosclerosis in angiographically normal carotid arteries. MATERIALS AND METHODS Forty-six arteries with 0% stenosis by MRA were evaluated with multicontrast carotid MR imaging at 3T. For each(More)
By means of Langendorff method and standard microelectrode techniques the effects of Ciwujia on reperfusion induced arrhythmias and action potential alterations were studied in isolated rat heart with transient coronary occlusion. Inclusion of Ciwujia extract (equivalent to 1.2 and 2.4 mg crude drug/ml) was found helpful in reducing reperfusion induced(More)
By means of microelectrode techniques the electrophysiological effects of a new class III antiarrhythmic agent, UK-68798 (Dofetilide), were investigated on atrionodal (AN), nodal (N), nodal-His (NH) and His (H) cells in the AVN area of rabbit heart. UK-68798 (5 x 10(-9) to 5 x 10(-6) mol/L) had no effect on APA and RP of the 4 kinds of cells but caused a(More)
OBJECTIVE To study the protective effect of alcohol extract of Plumula Nelumbini (AEPN) on carbon tetrachloride (CCl4) induced hepatic fibrosis rats and to explore its possible mechanism. METHODS Totally 32 male SD rats were randomly divided into four groups, i.e., the normal control group, the model group, the high dose AEPN group, and the low dose AEPN(More)
The effect of the new antiarrhythmic drug lorcainide was studied on the specialized conducting system of isolated canine ventricle. Transmembrane action potentials were recorded simultaneously from three subendocardial sites within the ventricular basis, free wall and apex. At concentrations of 3 x 10(-6) and 2.4 x 10(-5) M, lorcainide caused a(More)
By means of Langendorff method the isolated rat heart was perfused with Krebs Henseleit solution. Following ligation of the left descending coronary artery for 10 min the heart was reperfused for 3 min. The incidence of ventricular fibrillation in the reperfusion period was 100%, and the normal sinus rhythm time was shortened to 29 s within 3 min of(More)
