Neutrophil-gelatinase associated lipocalin (NGAL) is an iron-transporting this website protein with increased renal excretion in nephrotoxic
or ischemic kidney injury. We aimed to test the hypothesis that urinary NGAL measurement is useful to monitor acute kidney injury in cholemic nephropathy. Methods: Chow-fed (controls) or norUDCA (0.125% w/w)-treated CL57/BL6 mice were subjected to CBDL for 8 weeks. Urinary NGAL levels were determined at time of harvesting using a commercially available ELISA kit (Lipocalin-2/NGAL DuoSet Mouse, R&D Systems, DY1857). In brief, samples were incubated with detection antibody, labeled with streptavidin-HRP and subsequently measured at 450 nm. Results: Chow-fed CBDL mice exhibited significantly elevated
urinary NGAL levels (29.6 ± 4.2 ng/ ml) compared to norUDCA-treated CBDL mice (9.4 ± 1.8 ng/ ml, p<0.05). NorUDCA treatment significantly ameliorated the degree of selleck compound nephritis and kidney fibrosis and consequently to a significantly reduced renal hydroxyproline content (466 ± 107 μg/g vs. 797 ± 160 μg/g in controls, p<0.05). Conclusions: Urinary NGAL measurement represents a suitable readout for monitoring the degree of cholemic nephropathy in CBDL mice and reflects the therapeutic effects of norUDCA. Future studies should determine urinary NGAL levels in patients with cholemic nephropathy.

Rosenkranz Patients with cirrhosis develop hyperdynamic circulation with an increase in cardiac output (CO) and a decrease in systemic vascular resistance (SVR). Patients with hyperdynamic circulation can develop circulatory dysfunction(CD) when this compensatory mechanism is insufficient. Although this takes place theoretically in decompensated patients, namely in patients with ascites, its prevalence has never been specifically analysed.
