Parstatin prevents renal injury following ischemia/reperfusion and radiocontrast administration.
BACKGROUND/AIMS Parstatin is a 41-mer peptide formed by proteolytic cleavage on activation of the protease-activated receptor 1. Parstatin was recently found to be cardioprotective against myocardial ischemia/reperfusion (IR) injury. In the present study, it was hypothesized that parstatin would protect the kidneys in acute renal failure. METHODS We investigated the effects of parstatin on th...
متن کاملChanges in intrarenal oxygenation as evaluated by BOLD MRI in a rat kidney model for radiocontrast nephropathy.
The pathogenesis of radiocontrast nephropathy is poorly understood. In an animal model, inhibition of the synthesis of nitric oxide and prostaglandins appears to predispose rats to severe renal injury following the administration of radiocontrast. Here we have investigated whether administration of radiocontrast, as well as changes in renal medullary oxygenation following pharmacologic inhibiti...
متن کاملRenal Medullary Carcinoma; A Rare Entity
AbstractRenal medullary carcinoma (RMC) is an uncommon aggressive neoplasm of the kidney. RMC is biologically aggressive with a very poor prognosis, and metastasis is seen in up to 95% of the patients at diagnosis or shortly thereafter. The common sites of metastasis are respectively lymph nodes, lungs, livers, and adrenal glands in order of frequency. The presence of poorly differentiated eosi...
متن کاملFacilitation of human osteoblast apoptosis by sulindac and indomethacin under hypoxic injury.
Hypoxic-ischemia injury occurs after trauma causes consequential bone necrosis. Non-steroid anti-inflammatory drugs (NSAIDs) are frequently used in orthopedic clinics for pain relief. However, the underlying mechanism and outcome for usage of NSAIDs is poorly understood. To investigate the damage and loss of osteoblast function in hypoxia, two hypoxia mimetics, cobalt chloride (CoCl(2)) and des...
متن کاملAcute renal failure with selective medullary injury in the rat.
Since human acute renal failure (ARF) is frequently the result of multiple rather than single insults, we used a combination of treatments to induce ARF in rats. Uninephrectomized, salt-depleted rats injected with indomethacin developed ARF after administration of radiocontrast. After 24 h, the plasma creatine rose from 103 +/- 3 to 211 +/- 22 mumol/liter (mean +/- SE) and the creatinine cleara...
