Abstract

Leeches are widely used as model organisms in scientific studies and medical treatments. Medical leeches are hematophagous parasites that usually feed on the blood of their hosts. Some leeches show deformities, usually after feeding. This causes both medical and economic losses as it reduces the effectiveness of leeches in cultivation and medical treatment. The aim of this study was to investigate the effects of morphological deformations after feeding in Hirudo verbana, Carena 1820 (Annelida, Hirudinea), an important species in medical leech treatments. For this purpose, both histopathological and scanning electron microscopy examinations of starved and fed leeches were performed. The causes of deformities in medical leeches were found to be due to overfeeding, which caused cracks on the intestinal surface and therefore deterioration of the tissues. It is also thought that the immunological agents in the fed blood destroyed the medical leech tissue in these regions. In addition, it was determined that the cellular structure of the shaped blood elements stored in the cavity after feeding was preserved for a long time (months) without deterioration. It is certain that revealing the mechanism by which this occurs will inspire the preservation of blood for a long time in blood transfusion.

水蛭1820（环节动物，水蛭目）摄食后的形态和解剖畸形：光镜和电镜分析。

水蛭被广泛用作科学研究和医学治疗的模式生物。医用水蛭是食血寄生虫，通常以宿主的血液为食。有些水蛭通常在喂食后会出现畸形。这会造成医疗和经济损失，因为它降低了水蛭在种植和医疗中的有效性。本研究旨在探讨水蛭医学治疗中重要的水蛭种——水蛭（Hirudo verbana, Carena 1820）摄食后形态变形的影响。为此，对饥饿和喂食的水蛭进行了组织病理学和扫描电镜检查。医学水蛭畸形的原因被发现是由于过度喂食，导致肠道表面出现裂缝，从而导致组织恶化。也有人认为，喂食血液中的免疫因子破坏了这些区域的医学水蛭组织。此外，我们还确定了喂养后储存在腔内的定型血元的细胞结构保存时间较长（月），没有变质。可以肯定的是，揭示这种情况发生的机制将有助于在输血中长期保存血液。
