Abstract:
Objective:To study the relation between low density lipoprotein and macrophage myeloperoxidase.Methods:Using the reaction that MPO catalyze the oxidation of o dianisidin hydrochloride,MPO activity was determined.Using reverse transcription polymerase chain reaction(RT PCR),MPO gene expression was determined.The two methods were used to observe the relationship between low density lipoprotein and macrophage myeloperoxidase activity.Results:LDL was able to accelerate the hoist of MPO activity, but its effect is less than LPS OX LDL have no this effect When the time of LDL effect was prolonged, MPO activity was enhancing little by little When the concentration of LDL effect was increased, MPO activity was enhancing to max little by little, then it come to plateau Conclusion:LDL non especially induced the hoist of MPO activity and the swelling of MPO secretion The reason of the hoist of MPO activity was likely to make MPO into action and enhance its secretion, but not MPO gene expression
