    • Vasoactive polypeptide fractions having biological activity isolated in purified form from animal lungs induce peripheral vasodilation and systemic hypotension. One of the peptides exhibits the property of relaxing isolated non-vascular smooth muscle organs while the other peptide contracted these tissues. The peptide fractions are obtained from the lungs of animals by procedures involving boiling and mincing the lung, extracting the peptides into acetic acid, adsorbing by alginic acid, eluting with HCl and salting out, extracting into alcohol, again adsorbed with alginic acid, fractionating by gel chromatography, e.g. on Sephadex G-25, and by ion exchange chromatography, e.g. on carboxymethyl cellulose, followed by further ion exchange chromatography and, optionally, countercurrent distribution.
    • 具有从动物肺中纯化形式分离的生物活性的血管活性多肽部分诱导外周血管舒张和全身性低血压。 其中一种肽表现出放松分离的非血管平滑肌器官的性质,而另一种肽则缩小了这些组织。 通过涉及沸腾和切碎肺的方法从动物的肺获得肽级分,将肽提取到乙酸中,用藻酸吸附,用HCl洗脱并盐析,提取到醇中,再次吸收藻酸,通过 凝胶色谱法,例如 在Sephadex G-25上,并通过离子交换色谱法,例如 羧甲基纤维素,然后进一步离子交换层析和任选的逆流分布。
