BACKGROUND Although carvedilol attenuates left ventricular (LV) remodeling in coronary occlusion-reperfusion, it is not known whether it attenuates ischemic LV remodeling because of coronary stenosis (CS) or permanent coronary occlusion (CO). METHODS AND RESULTS We administered a vehicle, carvedilol, propranolol (2, 10, and 30 mg/kg per day, each),(More)
The aim of this research was to study and compare the mechanism of action of interleukin (IL)-8, IL-1beta dehydroepiandrosterone sulphate (DHEA-S) and prostaglandin (PG)E2 on the cervix. Five equal groups of pregnant rabbits (n = 45) were tested by either placebo or tested drugs in the form of vaginal suppositories once daily for 3 days. The suppositories(More)
Nonadrenergic noncholinergic nerve fibers supposedly modulate basal coronary flow by releasing capsaicin-sensitive neuropeptides, but the physiological effects of this intrinsic action have not been clarified. We investigated the intrinsic function of nonadrenergic noncholinergic innervation in modulating basal coronary flow in rats. We administered(More)
OBJECTIVE Infarct size (IS) reduction by ischemic preconditioning (IPC) has been assessed in the heart in which coronary stenosis (CS)-induced chronic ischemia was not present. The aim of this study is to assess whether and how IS reduction by IPC is modified in the heart in which CS has occurred, and how further therapeutics, if any, modify it. METHODS(More)
