摘要
【目的】寻找用于治疗尖吻蝮(Agkistrodon acutus)咬伤的中草药石柑子(Pothos chinensis)的药效实验证据。【方法】将制备所得石柑子水提物与尖吻蝮蛇毒混合孵育40min,检测混合液中蛇毒的磷脂酶A2活性、透明质酸酶活性、蛋白水解酶活性、出血活性、凝血活性和致死活性。【结果】石柑子水提物对尖吻蝮蛇毒的磷脂酶A2活性、透明质酸酶活性、蛋白水解酶活性、出血活性、凝血活性和致死活性都有明显抑制作用。【结论】研究结果初步证实了石柑子对尖吻蝮咬伤具有治疗效果。
[Purposes]To look for the experimental evidences for the efficacy of P.chinensis,a Chinese herbal medicine,used to treat the envenomings snake bitten by A.acutus.[Methods]After the aqueous extracts were prepared from P.chinensis,and they were incubated with A.acutus venom for 40 min,the activities of PLA2,hyaluronidase,protease and cagulationin the snake venom of the mixtures were examined in vitro assays,as well as hemorrhage activity and lethality activity in the snake venom of the mixtures were detected in vivo assays.[Findings]The aqueous extract of P.chinensis had obvious inhibition against the activities of PLA2,hyaluronidase,protease,hemorrhagic,coagulation and lethality of A.acutus venom.[Conclusions]Preliminary results revealed that P.chinensis has some treatment effects on A.acutus snakebites.
