Commu Bio:抗蛇毒血清太贵,研究者寻求更廉价毒蛇咬伤治疗方法

全世界每年有上百万人在热带地区被蛇咬伤和超过十万人因此死亡。如果有足够的对蛇种专一的抗蛇毒血清,这些死亡完全可以避免。抗蛇毒血清的昂贵和短缺的原因在于它的制造程序仍遵循上世纪的传统。

全世界每年有上百万人在热带地区被蛇咬伤和超过十万人因此死亡。如果有足够的对蛇种专一的抗蛇毒血清,这些死亡完全可以避免。抗蛇毒血清的昂贵和短缺的原因在于它的制造程序仍遵循上世纪的传统。

由于蛇种的地理分布和每种毒素的不同成分,抗蛇毒血清的制造是在不同的地区针对不同的蛇种进行。各地的研究蛇毒的机构会大量繁殖当地的蛇种,在上万次的少量收集每一种蛇毒之后,把蛇毒分别注入专门为此饲养的动物,比如马或者羊,然后进行重复的抽血。由于制作的时间较长和人力成本的因素,每个完整的抗蛇毒血清疗程的费用高达几万美金,这也导致了最容易被蛇咬伤的生活在热带农村的群体成为了最没能力负担疗程的群体。

为了降低抗蛇毒血清疗程的费用和普及其应用,英国利物浦热带医学学院的阿拉斯泰尔-里德蛇毒研究单位里由Nick Casewell博士带领的研究团队挑战了传统的制造抗蛇毒血清的策略,并于《通讯-生物学》期刊上发文(The paraspecific neutralisation of snake venom induced coagulopathy by antivenoms)。他们不再把蛇毒以地理区域划分,而是在病理层面上把蛇毒划分为四类:促凝血的,导致血流不止的,给神经系统带来损伤的,和导致细胞组织坏死的。他们设想,把抗蛇毒血清按以上四类集中生产,然后向各地输送,会大幅度地降低其生产成本。

Casewell博士的团队先集中研究促凝血的蛇毒。他们评估了57种蛇毒的促凝血活性,并比较了各种抗蛇毒血清的疗效。他们发现多数促凝血的蛇毒的分子机制都针对凝血级联通路里的几个核心的蛋白。他们还发现有些抗蛇毒血清对多种不同的蛇毒有交叉反应,这和之前的研究数据相符。这些数据支持了他们用病理把蛇毒分类的设想。沿着这个思路,他们制造出针对一种蛇毒但是能够中和多种蛇毒的抗体。最后,他们证明金属螯合剂乙二胺四乙酸(EDTA)也能够在小老鼠体内中和蛇毒。这些策略有制造抗蛇毒血清的经济替代品的潜力。

Nick Casewell博士说:“williamhill asia 希望能够发展一个可以应用于全球的、用规模经济大幅度地降低成本的模式,还有找出能够替代现在极昂贵的抗蛇毒血清的酶,从而让低收入的蛇咬伤者得到帮助。”

蛇毒让肝素治疗的患者手术更安全

对一些心肺疾病或手术,使用肝素等药物预防血栓已经是司空见惯的诊疗常规,但是使用药物抗凝的患者在术中止血就成了大问题,抗凝或抗血栓显然会导致血凝块不易形成,伤口不易愈合,出血风险增大。不过研究者已经找到了解决该问题的新方法。目前的医疗方案中,医生可以采取以下几种方法来减少使用肝素和其他血液稀释剂的患者的术中出血,包括压迫、缝合线、止血纱等。但是这些措施都存在潜在严重风险,一些会给患者带来毒副作用,导

我国科研人员在蛇毒中发现新型抗菌物质

来源:新华网   新华网记者16日从中国科学院昆明动物研究所获悉,该所科研人员在蛇毒中发现了新型蛇毒抗菌肽,可用于研发新型抗生素,具有不易产生耐药性、副作用小等优点,效果优于美国正在研制的同类药物。   该项目负责人中科院昆明动物研究所副研究员李文辉说,目前全球抗生素市场总额大约在300亿美元左右,但半个世纪以来没有开发出真正意义上的新型抗生素。随着传统抗生素的大量使用和滥用,在临床上出现了各

动物毒素研究:致命与治病的黑白两重天

几年前,巴西圣保罗市布坦坦研究所爬虫学部门负责人Kathleen Grego被巴西窝面蝰蛇(一种有毒的蝮蛇)咬伤,蛇的尖牙穿过她的手指甲,将致命毒液释放到Grego体内。Grego被送往医院并立即接受了抗蛇毒血清注射,但她的指甲仍留下一条垂直伤疤,其拇指顶端看起来向一边凹陷,这是由于毒素侵入了她的肌肉和其他组织。 巴西窝面蝰蛇毒液中的缩氨酸和蛋白质能侵袭调节血压和起凝固作用的分子,引发心
