  • Direct carotid-cavernous fistula [CCF] is a common post-traumatic disease. However, pseudoaneurysm formation after balloon occlusion is a rare complication. The author present such a case with review of the literature. A 26-year-old man involved in a motor vehicle accident as a driver. Only mild conjunctival injection and minimal exophthalmos on the right eye were noted after trauma. However, angiography revealed a direct CCF and dissection of the proximal intracranial internal carotid artery [ICA]. After first balloon occlusion of the CCF, the patient redeveloped fistula due to early deflation of the balloon. After the second balloon occlusion, pseudoaneurysm and diplopia were developed with the change of balloon position and shape. However, visual symptom spontaneously resolved and pseudoaneurysm was also decreased within 6 months after balloon occlusion.

  • Double-chambered right ventricle [DCRV] is a rare congenital heart disease caused by anomalous muscle bundle traversing the sinus portion of the right ventricle well beneath the infundibulum. Recently we have experienced a case of DCRV with ventricular septal defect in 7-year old male patient. Preoperative cardiac catheterization and cineangiography revealed 80 mmHg pressure gradient between the proximal and distal chamber of the right ventricle and diagonal shape filling defect by the anomalous muscle bundle in the sinus portion of the right ventricle. Resection of the anomalous muscle bundle and patch closure of the ventricular septal defect was performed with cardiopulmonary bypass. The postoperative course was uneventful and excellent.

  • Lobohalacarus weberi (Romijn and Viets, 1924) is added to the halacarid fauna of Korea as the third member of freshwater halacarid species. Both the genus and species are newly recorded from Korea. Halacarid mites were collected from two hillside wells and a streamside hyporheic zone in the southeastern region of South Korea. Lobohalacarus weberi is characterized by a well-developed frontal spine-like process, seven dorsal setae, the fourth segment of palp with a short distal and three long proximal setae, and tibiae of legs II to IV with two, one, two pectinate setae, respectively. A few minor individual variabilities were observed in the number of perigenital seta and genital acetabula, the setal armature on genua of legs, and the shape of spinule row on lateral claws.

  • A four months old, 3.6 kg intact female Miniature Dachshund dog was referred for non-weight bearing lameness at right hind limb due to car accident. On physical examination, the patient was non-weight bearing on the right hind leg and had moderate swelling in the proximal to middle tibia region. There was palpable crepitus. Radiographs revealed a slightly displaced, spiral, oblique fracture involving the proximal diaphyseal region of the right tibia. Fibular fracture was also noted. Internal fixation was performed to repair the fracture. Due to bowed shape of fractured tibia, it was not possible to apply K-wire, containing appropriate diameter ($60{\sim}80%$ of bone marrow diameter) for intramedullary fixation. We fixed the bowed tibia fracture using a smaller diameter (30% of bone marrow diameter) K-wire with cross pins and cerclage wires. Four weeks after the operation, radiographs demonstrated healing of the tibia fracture as well as the fibular fracture.

  • Purpose: The purpose of this study was to evaluate the frequency of troughing and stress fracture, which are the major complications of scarf osteotomy, and to suggest methods to prevent these complications. Materials and Methods: We reviewed 243 cases of 137 patients treated with the scarf osteotomy for hallux valgus from January 2005 to December 2012. The mean follow-up period was 2.8 years. During the scarf osteotomy, a long oblique longitudinal osteotomy was performed in order to decrease the possibility of troughing and stress fracture. Radiographs of lateral view of the foot were obtained and the thicknesses of the first metatarsal base at the sagittal plane were measured and compared. Results: There was no troughing during fragment translation and screw fixation intraoperatively. Radiographs of lateral view of the foot taken preoperatively and at the last follow-up showed that the mean thickness of the first metatarsal was 22.4 mm preoperatively and 21.6 mm at the last follow-up, with a mean difference of 0.8 mm. And no stress fracture was observed. Conclusion: To prevent troughing and stress fracture, a long oblique longitudinal cut, parallel to the first metatarsal plantar surface, was performed, making both ends of the proximal segment truncated cone-shape, and securing the strong bony strut of the proximal segment. No troughing or stress fracture was experienced with scarf osteotomy.

  • Leucosia anatum, also known as the pebble crab, is a species of crab that belongs to the family Leucosiidae. Crabs are the most conspicuous and abundant components of the epibenthic macrofauna of the mangrove ecosystems. The present investigation was carried out with the objective of enlightening the reproductive system of L.anatum through histological and histochemical studies. Histological analysis of the epithelial cells of vas deferens, the luminal size and shape of the vas deferens was carried out, since the spermatophore material is secreted and molded by the vas deferens. Histochemical analysis of the blood plasma, testis, proximal vas deferens, middle vas deferens, distal vas deferens, seminal plasma and spermatophore was done to reveal the possible transformation of their secretory materials into the spermatophoric components. Biochemical components present in the blood plasma, testis, proximal vas deferens (PVD), median vas deferens (MVD) and distal vas deferens (DVD) regions seminal plasma and spermatophore of pebble crab were analyzed to find out the quantity of free sugars, proteins, and fats. Thus the current study focuses on the histological and histochemical analysis of Testis and Vas Deferens and their secretions in L.anatum.

  • Two stichotrichid ciliates, collected from marine waters in Jeju Island, were identified as Afroamphisiella multinucleata Foissner et al., 2002 and Pseudokahliella marina (Foissner et al., 1982) Berger et al., 1985. They are recorded for the first time in Korea. The descriptions are based on examinations of living as well as protargol-impregnated specimens. These species are characterized as follows. Afroamphisiella multinucleata has a body size in vivo of $70-95{\times}20-35{\mu}m$; elongate rectangular in shape; contractile vacuole located slightly above mid-body. The adoral zone is bipartited into 3 distal and 13-17 proximal membranelles and occupies 28-35% of the body length. The frontal row comprises 1-4 cirri and one buccal cirrus. The amphisiellid median cirral row is composed of 14-21 cirri, 10-19 left marginal cirri, and 21-30 right marginal cirri. Cortical granules are yellowish. 11-20 globular/ellipsoidal macronuclear nodules arrange proximally along the cell margins. Pseudokahliella marina has a body size in vivo of $110-195{\times}40-110{\mu}m$ and broadly elliptical in shape. The adoral zone of the membranelles occupies 50-60% of the body length, and is composed of 41-70 membranelles. A prominent frontal scutum is present. The contractile vacuole is located below the mid-body. There are 11-13 frontoventral rows, including marginal rows. Caudal cirri and transverse cirri are absent. Three invariable non-fragmented bipolar dorsal kineties are present. The left and right marginal rows are composed of 22-35 and 28-40 cirri, respectively. Colourless cortical granules are present. 8-11 spherical/ellipsoidal macronuclear nodules are connected with each other by thread-like tructures, forming an inverted C-shape.
