Objective: To compare oxidized low density lipoprotein(ox LDL) levels in serum and vascular wall of Sprague-Dawley rats, identify their patterns in 8 weeks and 16 weeks of dyslipidemia induced by high fat diet, compare foam cells in aorta of each group and investigate lipoprotein-associated phospholipase A_2(Lp-PLA_2) role in atherosclerosis by darapladib ***: This study generated in twenty-four Sprague-Dawley rats. Rats were divided into 6 groups, which were received normal diet(normal group), high fat diet and high fat diet plus darapladib therapy for both 8 weeks and 16 weeks. Surgeries were performed at Week 8 and Week 16 to take the blood serum and aortic tissue. Level of ox LDL in serum,ox LDL aortic tissue, foam cell amount in aortic tissue, and Lp-PLA_2 expression in aortic tissue were ***: There were significant differences in ox LDL level in serum, aortic tissue and foam cell amount(P 0.9, P < 0.05).This study also composed an equation for ox LDL level in aortic tissue prediction. Factorial ANOVA found that there was a significant difference of ox LDL level in the interactions between duration and location, location and treatment, and also duration, location and treatment(P < 0.01). Administration of darapladib was able to reduce levels of ox LDL in serum,aortic tissue and foam cell significantly(P < 0.05, P < 0.05 and P < 0.01, subsequently).Conclusions: Ox LDL level is location-dependent and duration-dependent. As a feasible early diagnosis, we can predict ox LDL level in aortic tissue by its level in serum. Though Lp-PLA_2 expression was unsignificant, Lp-PLA_2 inhibition by darapladib can reduce oxidative stress and inflammation in atherogenesis.
