Abstract
Introduction. The kidney suffers ischemia-reperfusion (I/R) injury during transplanta-
tion. The purpose of the present study was to investigate the therapeutic effect of artificials
cells on renal I/R injury through biochemical assays and histological examination.
Methods. We prepared artificial cells using cross-linked hemoglobin (Hb), superoxide
dismutase (SOD), and catalase. Normal male Sprague-Dawley rats were divided into 6
groups: the sham-operated control group, the group treated with polyHb, and the group
treated with polyHb-SOD-catalase (PSC) (per groups were subjected to ischemia for 1
hour or 2 hours). After reperfusion for 4 hours, kidney and blood samples were obtained.
Results. The levels of SOD and catalase in the PSC group were 15 and 50 times higher
than those of the control group, respectively. In the polyHb group, the levels of blood urea
nitrogen (BUN), serum creatinine, renal hydrogen peroxide, and renal malondialdehyde
were increased. However, their levels were significantly decreased by PSC administration.
Renal SOD activity did not show any significant changes in the polyHb group, but renal
catalase activity was decreased by polyHb treatment in comparison with the control group.
The activities of renal SOD and catalase were increased using PSC treatment. In the
histological findings, the PSC group showed no evidence of acute tubular necrosis in
proximal convoluted tubules; their microvilli and cytoplasmic microorganelles were
relatively well preserved.
Conclusions. These results show that PSC effectively reduces renal damage via dimin-
ished oxygen free radical-mediated injury after I/R.
