Ischemia/reperfusion injury is the leading cause of acute tubular necrosis. Nitric oxide has a protective role against ischemia/reperfusion injury; however, the role of asymmetric dimethylarginine (ADMA), an endogenous inhibitor of nitric oxide synthase, in ischemia/reperfusion injury remains unclear. ADMA is produced by protein arginine methyltransferase(More)
Phosphate binders are useful for the treatment of hyperphosphatemia in hemodialysis (HD) patients. This study was performed to examine the effects of switching from calcium carbonate (CC) to lanthanum carbonate (LC) on bone mineral metabolism and inflammatory markers in HD patients. We conducted 29 stable HD patients receiving CC, which was replaced by LC(More)
BACKGROUND/AIM Matrix metalloproteinase-2 (MMP-2) has been implicated in chronic kidney disease (CKD) and cardiovascular disease. However, there is no knowledge about the correlations between serum levels of MMP-2, proteinuria and atherosclerosis in patients with CKD. We investigated whether serum MMP-2 levels were associated with proteinuria, intima media(More)
1. Regulatory T cells (T(reg)) and cytotoxic T cells (CTL) are involved in various immune diseases. However, the prognostic impact of T(reg) and CTL in patients with myeroperoxidase anti-neutrophil cytoplasmic antibody-associated glomerulonephritis (MPO-ANCA-GN) is not well known. Therefore, in the present study, we examined the relationship between(More)
In order to investigate otitis media with effusion from the systemic perspective, we have studied histological reactions of the mucous membrane in the both middle ears in the sensitized animals. Guinea pigs were initially immunized by injection of BSA conjugated with alum (BSA-alum) into unilateral tympanic cavity. The second challenge of BSA-alum was(More)
Peritoneal protein loss due to high peritoneal permeability may contribute to hypoalbuminemia and early withdrawal from peritoneal dialysis (PD) therapy in end stage renal disease (ESRD) patients. We have found that pigment epithelium-derived factor (PEDF) has anti-vasopermeability properties both in cell culture and animal models by counteracting the(More)
It is known that bacterial endotoxin on the outer surface of most gram-negative bacteria (GNB) is not only biologically active material, but also the modulator of the immune response. The earlier experiment documented that the endotoxin of killed Haemophilus influenzae was responsible for induction of chronic otitis media with effusion (OME). Recent study(More)
