| 中文摘要: |
| 本实验用体重7.5～11kg 犬18只,随机分成4组,用5%牛磺胆酸钠1 ml/kg逆行胰管注射制作 AHNP 模型,然后分别给予丹参（5g/Kg）、654-2（5mg/kg）和盐水静脉滴注。发现 AHNP 组早期 PaO2、PaCO2、pH 无明显改变,支气管肺泡灌洗浪 LDH、白蛋白、LPO 明显高于丹参组（P<0.05）,透射电镜下见肺血管内皮细胞坏死,连接中断和血管壁缺损,而丹参组肺血管内皮细胞和肺Ⅱ型上皮细胞正常,提示丹参具有保护肺毛细血管内皮细胞和肺Ⅱ型上皮细胞作用,可能是一种氧自由基的清除剂;654-2有保护细胞膜、减少白细胞溶酶体酶释放的作用,对急性出血坏死性胰腺炎致肺早期损伤有一定的保护作用。 |
| 英文摘要: |
| Experimental study had been conducted on 18 healthy adult mongral dogs of both sex,weighting from 7.5～11 kg,randomly divided into four groups.Experimental models of acute hemorrhagic necrotizing pancreatitis（AHNP）were established by retrograde injecting i ml/kg of sodium tauro- cholate directly into the pancreatic duct.The dogs were treated respectively with intravenous infusion of Salviae miltiorrhizae（5 g/kg）,654-2（5 mg/kg）or normal saline.The results showed that PaO2,PaCO2 and pH did not change in early stage of AHNP.The contents of lactic acid dehy- drogenase（LDH）,albumin and lipid peroxide（LPO）of bronchoalveolar lavage fluid in the AHNP group were significantly higher than that of Salviae miltiorrhizae group（P<0.05）.The necrosis and disruption of conjunction of endotheliai cells resulting from the defects of vascular wall were noted under transmission electron microscope.Both pulmonary vascular and type Ⅱ pneumocyte were normal in the Salviae miltiorrhizae group.These results suggested that Salviae miltiorrhizae possess the effect of protecting endothelial cells of pulmonary vascular and type Ⅱ pneumocyte,which could function as scavenger of oxygen-derived free radicals. |
