To investigate the effects of recombinant human adiponectin on the metabolism of diabeticswine induced by feeding a high-fat/high-sucrose diet (HFSD),diabetic animal models were constructedby feeding swine with HFSD for 6 months.The effects of recombinant adiponectin were assessed bydetecting the change of plasma glucose levels by commercially available enzymatic method test kits andevaluating the insulin sensitivity by oral glucose tolerance test (OGTT). About 1.5 g purified recombinantadiponectin was produced using a 15-liter fermenter.A single injection of purified recombinant humanadiponectin to diabetic swine led to a 2- to 3-fold elevation in circulating adiponectin,which triggered atransient decrease in basal glucose level (P<0.05).This effect on glucose was not associated with anincrease in insulin level.Moreover,after adiponectin injection,swine also showed improved insulin sensitivitycompared with the control (P<0.05).Adiponectin might have the potential to be a glucose-lowering agentfor metabolic disease.Adiponectin as a potent insulin enhancer linking adipose tissue and glucose metabolismcould be useful to treat insulin resistance.

More over, after adiponectin injection, swine also showed improved insulin sensitivitycompared with the control (P <0.05) .Adiponectin might have the potential to be a glucose-lower ing agent for metabolic disease.
