Limitation of HIF-1α with pentoxifillyne on renal tubular ischemia result of hiperoxaluria and ESWL.
Archivos Españoles de Urología 2014 March
OBJECTIVES: To evaluate hypoxia-inducible factor 1 subunit α (HIF-1α) expression during the performance of extracorporeal shock wave lithotripsy (ESWL) and to investigate the effects of pentoxyphylline on HIF-1α expression.
METHODS: One hundred New Zealand Albino rabbit were used in the study divided in 5 groups. There were 20 rabbits in each group. The groups were divided in two parts: early (7 days) and late period (14 days) according to follow up duration. Immunohistochemical analyses were performed using nuclear staining to show HIF-1α expression in rabbit renal tissue sample.
RESULTS: HIF-1α expression was higher in rabbits undergoing ESWL (group 4). In the hyperoxaluria group taking pentoxyphylline before ESWL (group 5), HIF-1α expression was lower in both early and late period subgroups (p < 0.05) CONCLUSION: In this study we evaluated HIF-1α expression and showed that ESWL may cause renal cell injury. Our results suggest that pentoxyphylline, as a circulatory regulator agent, may prevent renal cell injury induced by ESWL.
