En Colombia, Bothrops asper (mapaná) es la especie causante del 70 al 90% de los cerca de 3.000 accidentes ofídicos informados cada año. Durante varios siglos, la medicina tradicional ha utilizado plantas para el tratamiento de la mordedura de serpiente. En nuestro país, el 60% de las mordeduras son atendidas inicialmente por curanderos o chamanes, que usan al menos 100 especies de plantas medicinales en diferentes formas, de acuerdo al estado clínico del paciente. En este estudio se evaluó la capacidad inhibitoria de tres especies de la familia Heliconiaceae, H. latispatha Benth, H. wagneriana Petersen y H.curtispatha Petersen, sobre los efectos proteolítico, coagulante y hemolítico indirecto inducido por el veneno de Bothrops asper. La primera indujo un mayor porcentaje de inhibición del efecto hemolítico indirecto del veneno de B. asper que la Heliconia wagneriana, así como una reducción en la intensidad en las proteínas del veneno con masa molecular de 14 KDa, mientras que el extracto de la segunda planta mostró una mayor inhibición del efecto proteolítico inducido por el veneno de B. asper, así como mayores cambios en las bandas de proteína del veneno con masas moleculares entre 95 y 110 KDa. El extracto de Heliconia curtispatha, mostró la mayor capacidad inhibitoria de los efectos hemolítico, proteolítico y coagulante; además indujo una degradación de todas las proteínas del veneno completo de B. asper, como había sido reportado previamente.Downloads
