[Abstract]ObjectiveToinvestigate the efects of acetazolamideonatherosclerotic plaque formationand vascularcalcification in mice. MethodsFour-week-old Apoe-/-（n=3） and wild-type （ n=3 ） C57BL/6 mice were fed for 21 weeks，and subsequently，body weight and serum lipid levels were compared. Twelve l2-week-old Apoe-/- mice were divided into control group （ n=8 ，given normal saline） and experimental group （ ，given acetazolamide at 40mg/kg .After 2 weeks of treatment，aortic tissues wereharvestedtoevaluate plaquearea withHEstaining，characterizelipidcomposition withOilRedOstaining，measure calcium content using calcium assay kits，and determine the expression of carbonic anhydrase I （CA2）by Western blot. Results Apoe-/- mice exhibited significantly higher body weight and serum lipid levels than wild-type mice （F=24.15-61.24，t=2.891- 7.229，P<0.05） . At 3 months of age， plaque area，calcium content，and CA2 expression in aortic tissues were significantly increased in Apoe-/- mice （t=2.872-13.360，P<0.05） .Compared with controls，acetazolamide-treated Apoe-/- mice showed significantly reduced CA2 expresson，lipid-rich necrotic core area，and calcification severity （t=3.820-9.701，P<0.05） .ConclusionAcetazolamide attenuates atherosclerotic plaque formationand caleification by suppressing CA2 expressioninmice.
