摘要
目的探讨儿茶酚胺对大鼠血管内皮分泌功能的影响。方法利用大鼠异丙肾上腺素(ISP)心肌损伤模型,采用放免的方法测定血中内皮素(ET-1),前列腺素代谢产物6-酮前列腺素F1α(6-keto-PG1α)和血栓素B2(TXB2)的含量。结果试验组ISP导致血浆中ET-1明显增高;6-keto-PG1α含量明显降低而TXB2的含量明显增高。结论异丙肾上腺素损伤血管内皮分泌功能,从而可能影响血管的舒缩功能、血小板的凝血与止血的平衡状态,进一步导致心肌损伤及其他脏器的损伤。
Objective The effect of Isoproterenol on endocrine function of endothelial ceils in rat had been studied in the paper. Methods The radio-immunology assay was used to detect the radio-immune activity of ET- 1,6 - keto - PG1α and TXB2 in the plasma in the ISP myocardial damage model. Results ISP ean increase the radio - immune activity of ET - 1,6 - keto - PG1α and decrease the radio - immune activity of TXB2 in rat serum. Conclusion ISP can result in endothelial function damage that may play an important role in the development of thromohlic and vascular disease.
