In this article, a phyllidiid nudibranch which is distributed widely in the Indo-Pacific region, Phyllidia varicose Lamarck, 1801, is reported based on a specimen collected from Seopseom Islet, Jeju Island, Korea. This species is characterized by bluish-gray dorsal tubercles with a yellow cap and three distinct ridges consisting of dorsal tubercles going from the anterior to posterior region, the presence of bluish-black pigment between the dorsal ridges, and a characteristic black longitudinal stripe along the midline of the sole. In this study, we provide a key to species belonging to the genus Phyllidia discovered in Korea, the morphological descriptions, photographs, and a sequence of partial mitochondrial cytochrome c oxidase subunit I of P. varicosa. Currently, four species of the genus Phyllidia have been reported to be present in Korea, including P. varicosa.

A total of 21 patients were operated. Via a columellar labial incision, the upper lateral cartilages were separated from the septum. A submucous resection of the septal cartilage was carried out. After rasping the convex lateral nasal wall of the unaffected side, a low-to-low lateral nasal osteotomy was conducted. Along the deviated dorsal line at the bony vault passing the submucous tunnel, a paramedian nasal osteotomy was performed. The convex side of the nasal bone flap was contoured by rasping. The convex side of the "T"-shaped dorsal septum was trimmed. A total direct septal extension graft of the septal cartilage was done and the alar cartilages were suspended to it. The postoperative results were evaluated by photogrammetric analysis processed by a "neon glow" filter in Adobe Photoshop. The distance from the nasal midline to the most deflective point at 5 levels was measured, and the proportion indices were obtained in regard to intercanthal distance. The results revealed improvement in all levels (p < 0.05), although not perfect. In summary, this technique can result in a clinically good-looking in spite of a slight deflection that still exists

The objective of this study was to investigate the effects of implanted chitosan applied to surgically created wound in Japanese Macaque monkeys. 4 healthy Japanese Macaque monkeys were used. A 4 cm straight skin incision was made and undermined skin ($4{\times}4cm$) over on the 2 monkeys both sides of the dorsal midline, and a 4 cm circular skin incision was made on 2 monkeys both sides of the dorsal midline. One wound (left side) was implanted 1 mg (straight incision) and daily 0.2 mg (circular incision) of cotton type chitosan and the other wounds were treated with normal saline (3 ml) in monkeys. Each straight wound was closed with two interrupted sutures of 2-0 sutures. The monkey's circular skin incision is opened. At 14 days after initial wounding, each wound was taken for histological observations in monkeys. The inflammatory cells in the chitosan group are observed less than the control group, the collagen and the fibrin in the chitosan are observed more than the control group in monkeys. So the wound healing is moderately enhanced for chitosan treatment. The fibroblasts and the capillaries increased for chitosan treatment. The treatment of chitosan in wound is to promote healing.

Background Myelomeningocele is a frequently seen condition at tertiary care hospitals. Its treatment involves a variety of plastic reconstructive techniques. Herein, we present a series of myelomeningocele patients treated using keystone flaps. Methods We gathered information regarding soft tissue reconstruction and the use of bilateral keystone flaps to treat myelomeningocele patients. We obtained data from clinical records and recorded the demographic characteristics of mothers and children with the condition. The size, level of defect, and complications detected during the follow-up were analyzed. Results A series of seven patients who underwent bilateral keystone flaps for myelomeningocele closure was analyzed. There were no cases of midline or major dehiscence, flap loss, necrosis, surgical site infections, or cerebrospinal fluid leakage. No revision procedures were performed. Minor complications included one case with minimal seroma and three cases with areas of peripheral dehiscence that healed easily using conventional measures. Conclusions The use of keystone flaps is an adequate option for closure of dorsal midline soft tissue defects related to myelomeningocele. This technique offers predictable results with an acceptable spectrum of complications. Robust blood flow can be predicted based upon anatomical knowledge.

An 8-year-old, castrated male, Schnauzer dog was presented for evaluation of gradually worsening erythematous papules. Physical examination revealed multiple erythematous papules having a firm, gritty texture located in bilateral ears, dorsal midline, perianal and inguinal area. Skin biopsy revealed aberrant structure, characterized by atrophic epidermal-dermal layer structure with granular materials which was presumed as calcinosis cutis secondary to iatrognic hyperadrenocotricism. By initiating minocycline for 14 days, there was reduction in size, number of calcium deposit with remarkably decreased erythema. This case report presents the clinical trial of minocycline as a potential agent in treating dogs with calcinosis cutis.

Gynaecotyla squatarolae (Digenea: Microphallidae) adult flukes were recovered from experimental chicks at day 4-6 post-infection and their tegumental ultrastructure was observed with a scanning electron microscopy. They were pyriform in shape, and their anterior halves were concaved ventrally. The whole body surface was covered with tegumental spines, which were wide and 16-17 digitated between oral and ventral suckers. The density of spines and number of digits decreased posteriorly. The oral sucker was subterminal and the excretory pore was at the posterior end of the worm. Two ventral suckers were similar in appearance and protruded near midline of the worm. The genital atrium was dextral to the small ventral sucker. The dorsal surface was covered with tegumental spines, but the spines were sparser than on the ventral surface. On the middle portion of the dorsal surface, a small opening presumed to be the Laurer's canal was seen. From these findings, it has been confirmed that the adult G. squatarolae has unique characteristics in the surface ultrastructure.

Purpose: Since spinal tuberculosis is increasing in prevalence, it appears that a repair of spinal soft tissue defect as a complication of spinal tuberculosis can be a meaningful work. We report this convenient and practical reconstructive surgery which use bilateral latissimus dorsi musculocutaneous advancement flap. Methods: Before the operation, $13{\times}9.5$ cm sized skin and soft tissue defect was located on the dorsal part of a patient from T11 to L3. And dura was exposed on L2. Under the general endotrachel anesthesia, the patient was placed in prone position. After massive saline irrigation, dissection of the bilateral latissimus dorsi musculocutaneous flaps was begun just upper to the paraspinous muscles (at T11 level) by seperating the paraspinous muscles from overlying latissimus dorsi muscles. The plane between the paraspinous muscles fascia and the posterior edge of the latissimus dorsi muscle was ill-defined in the area of deformity, but it could be identified to find attachment of thoracolumbar fascia. The seperation between latissimus dorsi and external oblique muscle was identified, and submuscular plane of dissection was developed between the two muscles. The detachment from thoracolumbar fascia was done. These dissections was facilitated to advance the flap. The posterior perforating vasculature of the latissimus dorsi muscle was divided when encountered approximately 6 cm lateral to midline. Seperating the origin of the latissimus dorsi muscle from rib was done. The dissection was continued on the deep surface of the latissimus dorsi muscle until bilateral latissimus dorsi musculocutaneous flaps were enough to advance for closure. Once this dissection was completely bilateraly, the bipedicled erector spinae muscle was advanced to the midline and was repaired 3-0 nylon to cover the exposed vertebrae. And two musculocutaneous units were advanced to the midline for closure. Three 400 cc hemovacs were inserted beneath bilateral latissimus dorsi musculocutaneous flaps and above exposed vertebra. The flap was sutured with 3-0 & 4-0 nylon & 4-0 vicryl. Results: The patient was kept in prone and lateral position. Suture site was stitched out on POD14 without wound dehiscence. According to observative findings, suture site was stable on POD55 without wound problem. Conclusion: Bilateral latissimus dorsi musculocutaneous advancement flap was one of the useful methods in repairing of large spinal soft tissue defect resulting from spinal tuberculosis.

This study was designed to examine therapeutic effect of bee(Apis mellifera L.) venom in calves with bacterial diarrhea. Calves with bacterial diarrhea were administered with bee venom and therapeutic drug, respectively. In the bee venom-treated group, 69 calves were acupunctured once a day for 3 conseutive days. Two local acupoints of Jiao-chao(GV-1, at the indentation between the base of tail and the anus) and Bai-hui(GV -20, in the dorsal midline of the lumbo-sacral space) were stung by the bee. In the therapeutic drug-treated group, 55 claves were intramuscularly injected with a standard dosage of antibiotic (ciprofloxacin, 2.5 mg/kg of body weight) and antidiarrheal drug (berberine cholride, 10mg/head) once a day for 3 consecutive days. At post-treatment, 81.2% of the bee venom-treated calves and 76.4% of the therapeutic drugtreated calves were recovered from bacterial diarrhea. Bee acupuncture therapy showed in calves without side effects such as allergy hemorrhage, or infection. It might be concluded that apitherapy was affective in controlling of calves with bacterial diarrhea.
