ABSTRACT
Objective To investigate the expressions of intermedin /adrenomeduliin 2 (IMD/AM2) and its receptor calcitonin receptor-like receptor (CRLR) in the kidney of rats after renal ischemia reperfusion injury(IRI). Methods Male Wistar rats were divided randomly into two groups sham group and operation group. Renal IRI model was induced by clamping both renal arteries. Blood and kidney were harversted at 0 h, 6 h, 12 h, 24 h, 48 h, 72 h after reperfusion, respectively. Renal histological changes were semi-quantitated. Expressions of IMD and CRLR in the kidney were detected by Western blot, and the content of IMD in serum was measured by radioimmunity at 12 h, 48 h, 72 h after repeffusion. Results Kidneys of renal IRI model rats displayed significant pathologic changes, and the changes were much severer at 48 h after reperfusion. The expressions of IMD and CRLR in kidney were significantly up-regnlated at 12 h, 48 h, 72 h after renal IRI (P<0.01). The level of IMD in serum increased at 12 h, 48 h, 72 h after renal IRI (P<0.05). Conclusion The expressions of IMD and its receptor are up-regulated in the kidney after renal IRI, which may participate in the pathophysiological changes induced by renal IRI.
