中文摘要:

目的研究丹参多酚酸对心肌缺血损伤大鼠心肌酶与炎症因子水平的影响。方法按照体重将SD雄性大鼠随机分为4组:假手术组、模型组和低高2个剂量(丹参多酚酸18,36mg·kg^-1)实验组,每组15只,腹腔注射给药。假手术组和模型组按同等剂量注射蒸馏水,给药第4天,结扎冠状动脉左前降支建立心肌缺血模型。术后6h,眼内眦取血,以酶联免疫吸附法检测血清肌酸激酶(CK)、肌酸激酶同工酶(CK-MB)和乳酸脱氢酶(LDH)水平;于24h取心脏,苏木素一伊红(HE)染色,光学显微镜下观察心肌组织病理变化,酶联免疫吸附法检测血清血肌肌钙蛋白(CT胛)、肿瘤坏死因子α(TNF-01)和心肌组织匀浆髓过氧化物酶(MPO)含量。结果心肌缺血6h后,假手术组CK为(529.61±141.93)U·L^-1,CK-MB为(708.12±385.93)U·L^-1,LDH为(330.12±158.38)U·L^-1;模型组CK为(996.42±413.42)U·L^-1,CK-MB为(1346.11±558.30)U·L^-1,LDH为(520.12±154.76)U·L^-1;低高2个剂量实验组CK分别为(499.45±159.33),(514.91±98.82)U·L^-1,CK-MB分别为(831.42±385.11),(592.10±206.32)U·L^-1,LDH分另4为(462.62±229.68),(437.72±175.80)U·L^-1与假手术组相比,模型组大鼠血清CK、CK-MB、LDH水平明显升高,差异有统计学意义(P〈0.05);与模型组比较,低高2个剂量实验组能明显降低大鼠血清CK、CK-MB的含量,差异有统计学意义(均P〈0.05)。心肌缺血24h,假手术组和模型组cTnT分别为(294.12±55.10),(513.00±69.71)Pg·mL^-1,差异有统计学意义(P〈0.05);给药后,低高2个剂量实验组cTnT分别为(431.12±106.00),(338.80±76.92)Pg·mL^-1,与模型组比较,高剂量实验组差异有统计学意义(P〈0.05)。术后24h,假手术组和模型组TNF-α分别为(118.90±17.58)?

英文摘要:

Objective To investigate the protective effects of Salvianolic acid on myocardial ischemic injury of rats from the aspect of inhibiting inflammatory reaction. Methods Sixty Sprague Dawley (SD) male rats were randomly divided into four groups (n= 15 per group) : sham operation group, model group, experimental - high (36 mg · kg^-1 ) group, experimental - low ( 18 mg · kg^-1) group with intraperitoneal injection dosing. Same amount of distilled water was injected to sham operation group and model group, lasting for 4 days. Myocardial ischemia model was established by coronary artery ligation of left anterior descending (LAD) branch after the last administration. Six hours after the operation, the blood of eye canthus was collected to assay the levels of creatine kinase( CK), MB isoenzyme of creatine kinase (CK -MB) and lactate de- hydrogenase (LDH) in serum. The heart was collected 24 h after the operation, stained by hematoxylin eosin (HE) and checked the pathological change of the cardiac muscle tissue, assayed the cardiac troponin ( cTnT), tumor necrosis factor α (TNF -α) in serum and myeloperoxidase (MPO) was measured in myocardial tissue homogenate. Results After 6 hours' myocardial ischemia, the serum CK in sham operation group was (529.61 ± 141.93 ) U · L^-1, CK-MB was (708.12±385.93) U · L^-1, LDH was (330. 12 ± 158.38) U · L^-1 and cTnT was (294. 12±55.10) pg. mL-lafter 24 hours' myocardial ischemia. The serum CK in model group was (996. 42 +413.42) U · L^-1, CK-MB was (1346. 11 ±558.30) U · L^-1, LDH was (520. 12±154.76) U · L-land cTnTwas (513.00 ±69.71) pg · mL^-1 after 24 hours' myocardial ischemia. The serum CK in experimental- low and experimental -high groups were (499.45 ±159.33),(514.91±98.82)U · L^-1, CK-MB were (831.42 ±385.11),(592.10 ±206.32) U.L^-1 LDHwere (462.62±229.68) (437.72±175.80)U. L^-1 and cTnTwere (431.12±106.00) (338. 80±76. 92)pg · m
