  • Digit that were formerly assessed as non replantable may now be replanted with the help of salvage procedure. In case that, venous repair is either marginal or technically impossible and postoperative venous congestion developed following replantation, are treated with the application of medical leeches. From July 1997 to April 1998, the authors performed arterial anastomosis and venous drainage using medical leeches in 3 children(The age of the patients ranged from 13 months to 6 years.) to have a result of aesthetic and functional success with minimizing the complications. Leech therapy has many advantages, to avoid injuring of finger tip, to decrease focal capillary coagulation, to prevent severe bleeding, and to prevent thromboembolism. The authors conclude that the use of medical leeches shows promise as a safe and effective method of providing temporary venous drainage in replanted digits.

  • Dorsal and ventral epithelium of leech, Whitemenia edentula, were observed, using both light and electron-microscope. Results are as follows. Epithelia are composed of simple columnar or irregularly-shaped epithelium, the transveral folds were seen in the cross-sectioned dorsal and ventral epithelia, but only longitudinal folds(depth $500{\mu}m$, width $350{\mu}m$) were discovered in the ventral epithelium. As to muscular tissue under the dorsal epithelium of Whitemenia edentula, that of longitudinal muscle layer is thicker and more developed than that of circular muscle layer. Seven gland cells (type-A, B, C, D, E, F and H cells) and one pigment cell (type-G cell) were discovered in the whitemenia edentula. Those were identified as three kinds of the neutral mucopolysaccharide granoles (type-A, B and F cells), two kinds of acidic mucopolysaccharide granules (type-C and D cells), and two kinds of non-reactive granules respectively (type-E and F cells). The glanules of the type-A and type-B gland cells ae electronly high-dense, and surrounded by the muscular tissue. As to the distribution of gland cells, the type-A, type-B, type-C, type-D, type-I and type-H gland cells were discovered only between the connective tissue and the circular muscle layer, while type-F gland cells were discovered only between tile circular muscle layer and the longitudinal muscle layer.

  • Ear reconstruction is very difficult to perform and often results in a devastating deformity. The use of microsurgical replantation techniques has allowed very favorable anesthetic results. We report a case of a partial ear replantation without venous repair with the use of medicinal leeches to decompress the acute venous congestion during the postoperative care. The medicinal leech therapy can be very useful in a partial ear replantation in cases with no venous repair.

  • A kind of leeches, Trachelobdella sp was detected on the inside surface of the opercle of wild crucian carp, Carassius cuvieri (21.5 cm in length and 238.5 g in weight) at a reservoir for agriculture in ChungNam Province of Korea in March, 2002. Two or three round transparent spots on the opercle could be easily detected. The fish also showed severe anemia and dorsally darking in the gill lamellae. The parasites was identified as Trachelobdella sp. on the basis of morphological characteristics such as suckers, body segmentation and lateral diverticula. As the parasites fed on host blood after attaching on the inside surface of the opercle by means of the posterior sucker, they caused severe anemia and petechial haemorrhge on the gill of infested fish. Heavy infestation of the parasite resulted in dath of fish because of large amount of blood loss.

  • Traditionally, the Leech (Hirudo) has been used for the treatment of cerebral vascular diseases, cardiovascular diseases, women's diseases, etc. In Chinese medicine, usually Chinese medical doctors use Whitmania pigra Whitman among several species in their clinics. Because it was considered as toxic animal medicine according to related books, they used it in a parched form with Talcum powder, and this is the most general type for medication. Nowadays, however, many clinical doctors regard it as secure, so they tend to use it naturally in a capsule, in large quantities, and more frequently. We have no doubt that it is useful for diseases connected with blood stasis, especially including pulmonary diseases and allergic diseases, so we urge that many Korean oriental medical doctors use it practically in their clinics.

  • We have collected a great Quantity of leeches, comprising five species, from six different ponds and rice paddies in the south-western part of Korea. The leeches were cultured in our laboratory with special interests on the blood-suckers (Himdo nipponial in fresh water supplemented with essential ions. A number of experiments was carried out with biomedical aspects. We have observed traits which can be used as a laboratory animal. The paper reports general features obsenred from leeches with preliminary study results carried in culture systems. The paper also describes study aspects of leeches in biochemistry, neurology and developmental biology.

  • Turtle leeches have not been recorded in Korea, although they occur in geographically adjacent countries including China and Japan. This study describes a turtle leech, Ozobranchus jantseanus (Clitellata: Ozobranchidae), found from Reeve's turtle (Mauremys reevesii) in Korea. Of the 143 Reeve's turtles collected from the freshwater reservoir in Jinju City, Gyeongsangnam-do, Korea, 95 unidentified leeches were found in 8 (5.6%) individuals. The leeches had 22 somites with 11 pairs of externally exposed branchiae, body-sized posterior suckers, and spines on the dorsal surface. We identified these leeches as Ozobranchus jantseanus Oka, 1912 (Clitellata: Ozobranchidae). This species of turtle leeches found in Korea may fill the gap in the biodiversity of East Asian annulus.

  • To build a distribution model for Haemadipsa rjukjuana, we collected current occurrences of the species on Heuksando with adjacent islands. Based on current locations and 19 climate variables with DEM (digital elevation model), we built the MaxEnt (maximum entropy) species distribution model for H. rjukjuana in the islands. Then, we applied the MaxEnt model to the mainland of Korea with the current climate condition and topology. In addition to the current distribution scenario, we predicted the future distribution scenarios in Korea by Coupled Model Intercomparison Project Phase 6 (CMIP6) global climate models. Shared Socioeconomic Pathway (SSP) 585 of two CMIP6 models(GISS-E2-1 and INM-CM4-8) from 2040 to 2100 were used for the future projection.
