摘要
目的 :观察小牛血去蛋白提取物注射液(deproteinizedextractofcalfblood ,DECB)对培养的心肌细胞缺氧再给氧损伤的保护作用。方法 :以培养的心肌细胞为模型 ,在缺氧再给氧损伤细胞后 ,观察心肌细胞活力及搏动频率的变化 ,测定培养液上清乳酸脱氢酶的含量。结果 :DECB 0 .1及 0 .3g·L-1可以提高损伤后心肌细胞的活力 ,提高心肌细胞的搏动频率 ,并使培养液上清乳酸脱氢酶的含量明显降低。结论 :DECB对缺氧再给氧损伤培养的心肌细胞具有保护作用。
AIM : To explore the effects of DECB (deproteinized extract of calf blood, DECB) on hypoxia-reoxygenation-induced injury in cultured cardiac myocytes. METHODS : By using cultured myocardial cells as models, thenumber of death cells, beating frequency and the content of LDH were observed after hypoxia-reoxygenation-induced injury. RESULTS : 0.1 and 0.3 g·L -1 of DECB decreased the number of death cells and the content of lactate dehydrogenase (LDH), and restored the cellular beating frequency in the supernatant. CONCLUSION : DECB can protect the cultured myocardial cells against hypoxia-reoxygenation-induced injury.
