We compared liver volume and function kinetics after partial hepatectomy according to extent of resection and severity of coexisting liver disease in 57 adults with uneventful postoperative courses. Liver volume and massiveness of resection, or resection rate, were estimated on computed tomography. Patients were categorized into three groups on the basis of(More)
OBJECTIVE This study reports further refinement of a prediction scoring system, which was established in 1980 as a guide to determine a safe limit for hepatectomy, based on 10 years of use. SUMMARY BACKGROUND DATA In the past, whether major resection was safe was judged empirically from the net resection volume or the residual hepatic volume combined with(More)
1. We tested the effects on systemic haemodynamics and renal function, of inhibition of endopeptidase (EP) 24.15 (E.C. 3.4.24.15), in conscious uninephrectomized rabbits in which the activities of angiotensin converting enzyme (ACE, E.C. 3.4.15.1) and neutral endopeptidase (EP 24.11, E.C. 3.4.24.11) were already inhibited. To test the role of bradykinin(More)
To examine the utility of the single-dose captopril test in detecting renovascular hypertension (RVHT), the authors measured peripheral plasma renin activity (PRA), before and thirty and sixty minutes after an oral dose of captopril (25 mg), in 28 patients with RVHT and 22 patients with high-renin essential hypertension (EHT) without renal artery stenosis(More)
BACKGROUND Mesangial cell functions are critically regulated by platelet-derived growth factor receptor (PDGFR)-β signals. In contrast to the well-established role of PDGFR-β in the development of kidney glomerulus, its role in adult kidney glomerulus remains controversial. METHODS We deleted the PDGFR-β gene postnatally using the Cre-loxP system and(More)
This study was designed to investigate the changes in plasma and tissue endothelin-1/endothelin-2 (ET) after liver ischemia and to assess the protective effect of anti-ET 1/ET 2 monoclonal antibody (ET antibody) against ischemia-reperfusion injury. The ET levels in the liver tissue, hepatic venous blood of the ischemic and non-ischemic sides, and in the(More)
To examine the efficacy and usefulness of captopril-enhanced renal vein renin (RVR) measurements in detecting the functional significance of renal artery stenosis found in hypertensives, we compared these values in 22 patients with arteriographically documented renovascular hypertension due to unilateral (URVH: 14 patients) or bilateral renal artery(More)
PURPOSE Although autotransfusion is used in a wide variety of surgical procedures, it is largely unexplored for use in oncologic operations. This study evaluates the impact of autotransfusion in hepatectomy for hepatocellular carcinoma. PATIENTS AND METHODS Fifty-four patients with hepatocellular carcinoma underwent hepatectomy by receiving autologous(More)
To determine whether platelet response to mental stress is altered in essential hypertension, platelet aggregability and plasma beta-thromboglobulin were determined in 24 patients with essential hypertension (11 patients with World Health Organization (WHO) stage I and 13 patients with stage II) and 14 normotensive controls before and after a 10-min(More)
