Computed tomography with contrast medium is a common diagnostic tool in emergency and critical medicine. Contrast- induced nephropathy (CIN) is one of the leading causes of hospital- acquired acute kidney injury. Focus on renal tubule protection may be a hope to improve the effectiveness of current strategies.
We used HK-2 human renal proximal tubule cells to evaluate the therapeutic potential of resveratrol, a polyphenol phytoalexin produced naturally by several plants, for contrast ioxitalamate-induced toxicity in vitro. Cytotoxicity was determined by MTT assay. Patterns of cell death were observed by flow cytometry. Cytoplasmic DNA fragmentation was examined by ELISA. Western blots were used to analyze the expression of related proteins.
Resveratrol ameliorated apoptosis induced by contrast medium ioxitalamate in human renal proximal tubule cells. Investigations using animal models will be conducted in the future.
