Abstract

The in vivo model of the chick embryo chorioallantoic membrane (CAM) was used to study the involvement of nitric oxide (NO) in angiogenesis. The nitrovasodilator sodium nitroprusside (NaNP) and the amino acid, L-arginine, inhibited angiogenesis, assessed as both collagenous protein biosynthesis and vascular density. NG-monomethyl-L-arginine (L-NMMA), an NO synthase inhibitor, increased both collagenous protein biosynthesis and vascular density, indicating that this agent promotes angiogenesis. These results suggest that NO may participate in the regulation of angiogenesis. Manipulation of NO synthesis therefore, may prove to be another approach for controlling angioproliferative diseases.

摘要

采用鸡胚绒毛尿囊膜(CAM)的体内模型来研究一氧化氮(NO)在血管生成中的作用。硝血管扩张剂硝普钠(NaNP)和氨基酸L-精氨酸抑制血管生成,这通过胶原蛋白生物合成和血管密度来评估。NO合酶抑制剂NG-单甲基-L-精氨酸(L-NMMA)增加了胶原蛋白生物合成和血管密度,表明该药物促进血管生成。这些结果表明,NO可能参与血管生成的调节。因此,操纵NO合成可能被证明是控制血管增殖性疾病的另一种方法。
