Abstract: Objective To investigate the partial safety of the recombinant adenovirus containing the triple-point mutants HIF-1αgene (Ad-HIF-1α-Trip)transfection in a rabbit model of hind limb ischemia. Methods After ligation of left femoral artery, 22 New Zealand whites rabbits were randomly divided into 3 groups: saline group(n=6), Ad-Null group(n=6) and Ad-HIF-1α-Trip group(n=10). After operation, saline, Ad-Null and Ad-HIF-1αwere injected intramuscularly respectively. The expression of transferred HIF-1αat mRNA level in the ischemic skeletal muscle and other important organs were detected by Real-time PCR 10 days after gene transfection. The body temperature, weight, blood, liver and renal function, as well as the myocardial enzymes were detected before operation, and on the 3th, 7th, 14th and 28th day after gene transfection, so that pathological changes could be observed. Results On the 10th day after gene transfection, obvious expressions of HIF-1αat mRNA level in the ischemic limb were found, but no expression in other important organs was detected in Ad-HIF-1α-Trip group. The blood routine, liver and renal function were all in the normal range (P > 0.05). No abnormalities were found in heart, liver, kidney, and lung HE transfection in Ad-HIF-1α-Trip group. Conclusion Single intramuscular injection of Ad-HIF-1α-Trip can be expressed obviously in the ischemic limb without detected damage of liver , cardiac and kidney.%
