摘要: 目的: 研究中华眼镜蛇毒活性组分的抗血管生成作用。方法: 采用拟血管生成三维培养法, 观察活性组分对体外血管生成的抑制效应。结果: 活性组分可抑制内皮细胞在培养基质中生成血管网状三维结构的反应, 0. 6 、1. 2 、2. 4 μg·ml-1的不同浓度组分抑制程度不同。在0. 6 μg·ml-1 浓度组, 培养基质Matrigel 中的内皮细胞团只形成局部的、不完整的空间网状结构;在1. 2 μg·ml-1 浓度组, 悬浮于凝胶中的细胞团所形成的管芽不能相互连接而形成空间网状结构;在2. 4 μg·ml-1 浓度组, 细胞散在悬浮于胶层中大部分不能粘聚, 且随培养时间的延长无明显的结构变化。结论: 中华眼镜蛇毒活性组分具有体外抑制血管生成的生物活性。

Abstract: AIM: To study the anti-angiogenesis effects of the active fraction separated from Naja Atra venom.METHODS: The inhibiting effect of active fraction in angiogenesis was detected by the three-dimensional angiogenesis model. RESULES: The active fraction in different concentrations inhibit the action that vascular endothelial cells (ECs) developed into three-dimensional capillary-like networks in vivo. ECs in matrigel only developed into incomplete capillary-like networks in 0. 6 μg·ml-1 dose group, the sprouts differentiated from ECs did not spread and contract each other and form the nets in 1. 2mg·L-1 dose group, ECs did not adherent together and alternate in 2. 4 mg·L-1 dose group.CONCLUSION: The active fraction separated from Naja Atra venom has the anti-angiogenesis effect in in vitro.
