objective to investigate whether hypoxia preconditioning exist in adipose tissue,and construct the hypoxemic model of adipose tissue.methods after injected different density cocl2 to rat's subcutaneously of groin,use immunohistochemical method detect hif-1α protein,and use rt-pcr detect hif-1α mrna.results after injected different density cocl2,the adipose tissue of rat's groin express different degree of hif-1αprotein and hif-1αmrna.,and reach the peak when the density is 20-40 mg/kg and the time is 3 h.conclusion hypoxia preconditioning exist in adipose tissue,and the effect of preconditioning is most evidence when the density is 20-40 mg/kg and the time is 3 h.
