目的:探讨外源性基质金属蛋白酶9(MMP-9)抑制剂巴马司他对高血压小鼠血压及其血清中MMP-9水平和活性的影响。方法将36只高血压小鼠(高血压组)平均分为3个亚组,每组12只,连续3 d分别以巴马司他30 mg/kg(高剂量亚组)、10 mg/kg(低剂量亚组)和生理盐水(对照亚组)对小鼠腹腔进行注射,依次在最后1次注射后0 h、2 h、4 h、6 h对各组小鼠血清中MMP-9及其mRNA水平进行检测;应用明胶酶谱法检测各组小鼠血清中MMP-9活性。选择健康小鼠36只为健康对照组,检测血清MMP-9、mRNA水平,并与高血压组比较。结果(1)血压变化:与健康对照组比较,高血压组用药前血压较高,差异有统计学意义( P <0.05),用药后,与对照亚组及低剂量亚组比较,高剂量亚组血压降低,差异均有统计学意义( P <0.05)。(2)血清MMP-9浓度:与健康对照组比较,用药前高血压组MMP-9蛋白浓度显著高( P <0.01),用药后,组内比较:高剂量亚组和低剂量亚组小鼠血清中MMP-9蛋白表达水平均随着药物作用时间的延长而降低,差异均有统计学意义( P <0.05, P <0.01);与低剂量亚组、对照亚组比较,高剂量亚组在2 h、4 h、6 h血清MMP-9浓度均较低,差异均有统计学意义( P <0.05, P <0.01);低剂量亚组与对照亚组比较,2 h、4 h、6 h差异亦均有统计学意义( P <0.05)。(3)MMP-9 mRNA表达:与健康对照组比较,高血压组MMP-9 mRNA水平显著升高( P <0.05);用药后,高剂量亚组和低剂量亚组小鼠血清中MMP-9 mRNA水平均随着药物作用时间的增加而降低,差异均有统计学意义( P <0.05, P <0.01);对照亚组、低剂量亚组、高剂量亚组两两比较差异均有统计学意义( P <0.05, P <0.01)。(4) MMP-9活性测定:随着巴马司他给药剂量的增加,Pro-MMP-9和Active-MMP-9活性呈减弱趋势。结论巴马司他能够降低高血压小鼠血压水平及其血清中MMP-9水平和活性。
目的:探討外源性基質金屬蛋白酶9(MMP-9)抑製劑巴馬司他對高血壓小鼠血壓及其血清中MMP-9水平和活性的影響。方法將36隻高血壓小鼠(高血壓組)平均分為3箇亞組,每組12隻,連續3 d分彆以巴馬司他30 mg/kg(高劑量亞組)、10 mg/kg(低劑量亞組)和生理鹽水(對照亞組)對小鼠腹腔進行註射,依次在最後1次註射後0 h、2 h、4 h、6 h對各組小鼠血清中MMP-9及其mRNA水平進行檢測;應用明膠酶譜法檢測各組小鼠血清中MMP-9活性。選擇健康小鼠36隻為健康對照組,檢測血清MMP-9、mRNA水平,併與高血壓組比較。結果(1)血壓變化:與健康對照組比較,高血壓組用藥前血壓較高,差異有統計學意義( P <0.05),用藥後,與對照亞組及低劑量亞組比較,高劑量亞組血壓降低,差異均有統計學意義( P <0.05)。(2)血清MMP-9濃度:與健康對照組比較,用藥前高血壓組MMP-9蛋白濃度顯著高( P <0.01),用藥後,組內比較:高劑量亞組和低劑量亞組小鼠血清中MMP-9蛋白錶達水平均隨著藥物作用時間的延長而降低,差異均有統計學意義( P <0.05, P <0.01);與低劑量亞組、對照亞組比較,高劑量亞組在2 h、4 h、6 h血清MMP-9濃度均較低,差異均有統計學意義( P <0.05, P <0.01);低劑量亞組與對照亞組比較,2 h、4 h、6 h差異亦均有統計學意義( P <0.05)。(3)MMP-9 mRNA錶達:與健康對照組比較,高血壓組MMP-9 mRNA水平顯著升高( P <0.05);用藥後,高劑量亞組和低劑量亞組小鼠血清中MMP-9 mRNA水平均隨著藥物作用時間的增加而降低,差異均有統計學意義( P <0.05, P <0.01);對照亞組、低劑量亞組、高劑量亞組兩兩比較差異均有統計學意義( P <0.05, P <0.01)。(4) MMP-9活性測定:隨著巴馬司他給藥劑量的增加,Pro-MMP-9和Active-MMP-9活性呈減弱趨勢。結論巴馬司他能夠降低高血壓小鼠血壓水平及其血清中MMP-9水平和活性。
