Fig. 5From: Application of diffusion tensor imaging and blood oxygenation level-dependent magnetic resonance imaging to assess bilateral renal function induced by Iohexol in rabbitsHIF-1α expression following contrast injection via the right renal artery (× 400) (n = 3). The right renal HIF-1α expression increased precipitously at 24 h (*P < 0.05 vs. baseline. Baseline was normal renal tissue and the HIF-1α expression score was 0.).
