Abstract

Natural, sulfated and recombinant, non-sulfated hirudin preparations re-isolated from urine after kidney passage were compared with the corresponding administered preparations by reversed-phase high-performance liquid chromatography, and by amino acid sequence and composition analysis. It could be demonstrated that the hirudins were excreted in unmodified form. Natural hirudin could be fractionated by the chromatographic system used into a large number of isoinhibitor forms, some of which were shown to differ from each other in their amino acid sequence.

Резюме

Natural sulfated and recombinant non-sulfated hirudin re-isolated from urine excreted in unmodified form; multiple hirudin isoinhibitor forms differentiable by HPLC.

Почему это важно для гирудотерапии

This study compared natural, sulfated and recombinant, non-sulfated hirudin preparations re-isolated from urine after kidney passage with the corresponding administered preparations, using reversed-phase HPLC and amino acid sequence and composition analysis. The findings demonstrated that both hirudin forms were excreted in unmodified form, and that natural hirudin could be fractionated into multiple isoinhibitor forms, some differing in amino acid sequence. Hirudin is an anticoagulant substance from medicinal leeches, making this study relevant to understanding the structural stability and heterogeneity of a leech-derived anticoagulant. However, the abstract does not specify the species studied, the investigation examines isolated hirudin rather than whole leech therapy, and there is no direct hirudotherapy or leech application component described, so its relevance to clinical practice is indirect.
