The angiotensin II (AII) antagonistic action of 2-ethoxy-1-[[2'-(1H-tetrazol-5-yl)biphenyl-4-yl]methyl-1H-benzi mid azole-7 - carboxylic acid (CV-11974) was examined in in vitro assay systems, including AII receptor binding assay using membrane fractions of bovine adrenal cortex or rabbit aorta and AII-induced contraction assay using rabbit aortic strips,(More)
The effects of chronic treatment with an angiotensin II receptor antagonist, candesartan cilexetil (TCV-116, 0.1, 1, 10 mg/kg), and an angiotensin converting enzyme inhibitor, enalapril maleate (enalapril, 10 mg/kg), on the development of end-organ damage were examined in stroke-prone spontaneously hypertensive rats (SHRSP). The control SHRSP developed(More)
The angiotensin II (AII) antagonistic action of CV-11974 (2-ethoxy-1-[[2'-(1H-tetrazol-5-yl)biphenyl-4-yl]methyl] benzimidazole-7-carboxylic acid) was investigated in an AII-receptor binding assay using rabbit aortic membranes and an AII-induced contraction assay using rabbit aortic strips. A single class of [125I]AII-(Sar1,Ile8) binding sites was found in(More)
The mechanisms of the insurmountable antagonism of 2-ethoxy-1-[[2'-(1H-tetrazol-5-yl)biphenyl-4-yl]methyl]1H-benzimid azole -7-carboxylic acid, candesartan (CV-11974), an angiotensin AT1 receptor antagonist, on angiotensin II-induced rabbit aortic contraction were examined in contraction and binding studies. Preincubation of the rabbit aorta with CV-11974(More)
The antihypertensive effects of (+-)-(cyclohexyloxycarbonyloxy)ethyl2-ethoxy-1-[[2'-(1H- tetrazol-5- yl)biphenyl-4-yl]methyl]-1-H-benzimidazole-7-carboxylate (TCV-116), an angiotensin II (AII) subtype-1 receptor antagonist, were studied in various hypertensive and normotensive rats, using 2-n-butyl-4-chloro-5-hydroxymethyl-1-[(2'-(1H-tetrazol-5-yl)bip hen(More)
Antihypertensive effects of an angiotensin (Ang) II receptor antagonist, candesartan cilexetil (TCV-116), were compared with those of an angiotensin converting enzyme (ACE) inhibitor, enalapril, in spontaneously hypertensive rats (SHR), 2-kidney, 1-clip hypertensive rats (2K, 1C-HR) and 1-kidney, 1-clip hypertensive rats (1K, 1C-HR). CV-11974, the active(More)
In dispersed rabbit adrenocortical glomerulosa cells, a non-peptide angiotensin II (AT1) receptor antagonist, CV-11974 (10(-10)-10(-5) M), competitively inhibited angiotensin II- or angiotensin III-stimulated aldosterone production, whereas PD123177, an angiotensin AT2 receptor antagonist, did not. CV-11974 inhibited aldosterone production induced by 4 mM(More)
Spiral computed tomography (SCT), which consists of rapid volumetric data acquisition and planar image display, was performed on 12 patients with biliary dilatation after excisional procedure. The technique was evaluated for image quality and impact on clinical practice. All patients safely underwent SCT scanning after intravenous cholangiography (IVC)(More)
To clarify the risk factors contributing to postoperative complications in the elderly patients (over 70 years) undergoing esophagectomy and/or gastrectomy, 364 patients with primary cancer seen were evaluated. As a result, some characteristic patterns of stress response in the elderly could be detected as follows: the disorders of the vital organs were(More)
In April 1984, a 49-year-old male underwent a partial gastrectomy for advanced gastric cancer. At that time, many metastatic foci were found, for example, in the rib, the lumbar vertebrae, the cervical vertebrae, and in the abdominal lymph nodes. Approximately one year later, he suddenly became disturbed and lost consciousness. A metastatic brain tumor was(More)
