Microalbuminuria is an early sign of nephropathy and an independent predictor of end-stage renal disease. The purpose of this study was to assess microalbuminuria prevalence and its contributing factors in Korean hypertensive patients. This cross-sectional study enrolled male and female patients of ⩾35 years old with an essential hypertension diagnosis as(More)
BACKGROUND Idiopathic focal segmental glomerulosclerosis (FSGS) occurring at young age is known to predispose to poor graft outcome, but the outcome of adulthood-onset FSGS (A-FSGS) has not been thoroughly investigated. Here, we compared the graft outcomes between kidney recipients with A-FSGS and childhood-onset FSGS (C-FSGS). METHODS We enrolled 47(More)
Pulmonary fibrosis is a potentially life-threatening disease that may be caused by overt or asymptomatic inflammatory responses. However, the precise mechanisms by which tissue injury is translated into inflammation and consequent fibrosis remain to be established. Here, we show that in a lung injury model, bleomycin induced the secretion of IL-6 by(More)
Race and ethnicity are influential in estimating glomerular filtration rate (GFR). We aimed to find the Korean coefficients for the Modification of Diet in Renal Disease (MDRD) study equations and to obtain novel proper estimation equations. Reference GFR was measured by systemic inulin clearance. Serum creatinine (SCr) values were measured by the alkaline(More)
BACKGROUND AND PURPOSE Restless legs syndrome (RLS) is a sleep disorder that frequently occurs in dialysis patients, which disturbs the sleep and reduces the quality of life. The aim of this study was to determine the risk factors for RLS in dialysis patients. METHODS Patients who visited any of four outpatient dialysis clinics between September 2005 and(More)
Matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) are important in the endometrial remodeling process during embryonic trophoblast invasion. Previous studies, using in situ hybridization, revealed that the predominant proteinase expressed by the implanting mouse embryo is matrix metalloproteinase-9 (MMP-9), and the major tissue inhibitor(More)
BACKGROUND Wide variation in tacrolimus concentrations and low tacrolimus exposure have been reported to be associated with poor renal graft outcomes in non-Asians. The CYP3A5 polymorphism is a representative genetic factor that might affect this association, together with environmental factors. We investigated whether tacrolimus variability or the mean(More)
BACKGROUND Oxidative stress is a major mediator of adverse outcome after kidney transplantation. Bilirubin is produced by heme oxygenase-1 (HO-1), catalyzed by UDP-glucuronosyltransferase (UGT1A1), and has potential as an antioxidant. In this study, we investigated the effects of HO-1 and UGT1A1 sequence variations on kidney allograft outcomes. METHODS(More)
BACKGROUND Tacrolimus is a major immunosuppressant, which has a narrow therapeutic range and wide interindividual variation. The effects of genetic polymorphisms of cytochrome P450 3A (CYP3A) 5 and Adenosine triphosphate-binding cassette subfamily B member 1 (ABCB1) genes on the achievement of target tacrolimus trough levels and clinical outcomes in renal(More)
BACKGROUND Chronic psychological stress-induced alterations in visceral sensitivity have been predominantly assessed in male rodents. We investigated the effect of acute and repeated water avoidance stress (WAS) on the visceromotor response (VMR) to colorectal distension (CRD) and the role of opioids in male and cycling female Wistar rats using a novel(More)
