The Ethiopian endemic snake of the species recognized for its colorful patterns, might be more interesting as we look deeper into the venom activity. We assayed the effects of venoms from the most widespread venomous African and closely related species using The Hen's Egg Test-Chorioallantoic membrane test (HET-CAM) and Chicken embryotoxicity screening test (CHEST), acetylcholinesterase (AChE) analysis, cytotoxicity assay performed on cell lines and protein analysis of selected venoms. Our results indicated that venom contains vasoactive compounds that have a direct effect on blood vessels. The AChE analysis showed significant ability inhibiting AChE activity in embryonic tissue. Cytotoxicity observed on A549 ATCC CCL-185™ cells indicates the possible presence of cytotoxic agents in venom. We proved previously described differences in the composition of venom obtained from and by using electrophoresis and total protein concentration. Based on similarities in vasoactive effects observed after administration of venoms onto a chicken chorioallantoic membrane, we suggest that venom from and might share certain venom proteins responsible for haemotoxicity. The main active components of venom are unknown. Our results suggest that it might be worth performing proteomic analysis of venom as it might contain medically valuable compounds.
埃塞俄比亚特有的蛇种因其丰富多彩的图案而引人注目,而深入研究其毒液活性可能会更有趣。我们使用鸡胚绒毛尿囊膜试验(HET-CAM)和鸡胚毒性筛选试验(CHEST)、乙酰胆碱酯酶(AChE)分析、细胞系细胞毒性试验以及对选定毒液的蛋白质分析,检测了分布最广泛的非洲毒蛇和密切相关的蛇种毒液的作用。我们的结果表明,该蛇种的毒液含有血管活性化合物,对血管有直接影响。AChE 分析表明,毒液对胚胎组织中 AChE 活性具有显著的抑制能力。在 A549 ATCC CCL-185™细胞上观察到的细胞毒性表明,毒液中可能存在细胞毒性物质。我们通过电泳和总蛋白浓度分析,证明了从和获得的毒液在组成上存在先前描述的差异。基于在鸡绒毛尿囊膜上给药后观察到的血管活性效应的相似性,我们推测和的毒液可能共享某些负责血液毒性的毒液蛋白。的毒液的主要活性成分尚不清楚。我们的结果表明,对毒液进行蛋白质组学分析可能是值得的,因为它可能含有有医学价值的化合物。
