A 15 months old male pit bull terrier was shown submandibular swelling, which was extended from left submandibular area through mandibular symphysis to right submandibular area and toward around left neck. In history taking, recurrence of swelling was recorded after conservative surgical incision, drainage and dressing. Palpation revealed no pain and heating, partial flutuation and hardness. By paracentesis, it was showed blood-tinged tenacious exudate without bad-smelling. Left submandibular salivary gland was able to be movable freely and the size decreased to half of that of right submandibular salivary gland. It was diagnosed as cervical salivary mucocele. In operation, rostral portion of left sublingual salivary gland was observed to be damaged transversely, showed black color and leaked saliva. Submandibular gland and rostral portion of sublingual salivary gland were resected, after ligation of ducts of submandibular and sublingual salivary glands. At 15 days postoperation, serosanguineous exudate from operation wound was dramatically decreased and stable granulation tissue mass at this area was first palpated. At 39 days after operation, outline of left and right mandibular was appeared normal and skin tenderness of mandibular area was equal to that of the other body wall.

Aspirin has usually been taken for pain relief originating in the nidus of osteoid osteoma, however it takes too long to become effective. Because of the protracted painful course and the unpredictability of regression, osteoid osteoma is usually removed. And then, the defective host bone is internally fixed by plate and screws and augumented by autogenous bone graft. However, the common intracortical location and exuberant periosteal reaction hinders the exact intraoperative localization of the nidus. The authors managed 6 patients by computerized tomography-guided percutaneous nidus excision with a relatively small skin incision, small cortical window, short operation time and no bone graft. It may be one of the best options for removal of the nidus of osteoid osteoma with certainty.

Endoscopic spine surgery is an advanced surgical technique for spinal surgery since it minimizes skin incision, muscle damage, and blood loss compared to open surgery. It requires, however, accurate positioning of an endoscope to avoid spinal nerves and to locate the endoscope near the target disk. Before the insertion of the endoscope, a guide needle is inserted to guide it. Also, the result of the surgery highly depends on the surgeons' experience and the patients' CT or MRI images. Thus, for the training, a number of haptic simulators for spinal needle insertion have been developed. But, still, it is difficult to be used in the medical field practically because previous studies require manual segmentation of vertebrae from CT images, and interaction force between the needle and soft tissue has not been considered carefully. This paper proposes AI-based automatic vertebrae CT-image segmentation and haptic rendering method using the proposed need-tissue interaction model. For the segmentation, U-net structure was implemented and the accuracy was 93% in pixel and 88% in IoU. The needle-tissue interaction model including puncture force and friction force was implemented for haptic rendering in the proposed spinal needle insertion simulator.

We report a case of polycythemia vera combined with coagulation disorder. The patient was 54 years old man who complained of continuous bleeding after incision of skin abscess 20days ago. Laboratory tests were revealed prolonged aPTT and slightly prolonged PT. Coagulation factor, I, VIII, IX, XI and fibrinogen decreased, however FDP did not increased. It appears that patient with polycythemia vera have chronic activation of coagulation system, probably initiated by activation of factor XII. Platelet aggregation test to ADP, collagen, epinephrine was also revealed poor response.

We examined the in vivo efficacy of ultra-high molecular weight poly-γ-glutamic acid (UHMW γ-PGA) for wound healing. The wound area was measured by a ruler and documented by digital photography before the animals were sacrificed at days 8 and 16 post wounding. The areas of wounds treated with UHMW γ-PGA were significantly decreased on days 8 and 16, as compared with those receiving a control treatment, and more than 70% of the UHMW γ-PGAtreated area was repaired by day 8. Hematoxylin and eosin staining confirmed that the epidermis had regenerated in the UHMW γ-PGA-treated wounds. At 16 days post wounding, collagen pigmentation and cross-linking were increased as compared with the control groups, and greater regeneration of blood vessels had occurred in UHMW γ-PGA-treated groups. Increased levels of transforming growth factor-beta and β-catenin were also observed in skin samples collected from UHMW γ-PGA-treated animals on days 8 and 16 post incision. Taken together, these findings suggest that UHMW γ-PGA promotes wound healing in vivo.

Objective : The purpose of this study is to investigate the clinical results of anterior and posterior stabilization by one stage posterolateral approach for the unstable fracture of thoracolumbar and lumbar spine. Methods : By posterolateral approach with curved skin incision, unilateral facet and pedicle were removed. Through this route, corpectomy was performed, and then this space was replaced with mesh cage filled up with autologous bone graft. Both side pedicle screw fixation was followed to upper and lower levels. Results : Six of seven patients of this study showed neurological improvement. The other one patient showed no neurological change. One patient had postoperative infection, another patient had postoperative kyphosis. The other patient had epidural hematoma on operation site after surgery. And all patinets on this study made to have spinal stability except one patient happened postoperative kyphosis. Conclusion : In the unstable fracture of thoracolumbar and lumbar spine, one stage anterior and posterior stabilization and fusion by posterolateral approach seems to be an effective procedure, if we have more care and supplementation.

A 120 kg, 3-year-old, male ostrich (Struthio camelus) was submitted to the veterinary teaching hospital, Chonbuk national university, for chronic weight loss, anorexia, small hard fecal pellets, and lethargy. Illness was first noticed approximately 2 weeks before submission. Although the bird was able to stand, he was extremely weak and cachectic. Blood examination indicated that the bird was dehydration (PCV: 55%). Fluoroscopic and lateral abdominal radio-graphic view indicated impaction of distended proventriculus with bigger rocks than normal. Anesthesia was induced with ketamine (10 mg/kg, IV)-xylazine (1 mg/kg, IV) combination and maintained with ketamine (10 mg/kg, IV) at intervals of 8 to 15 minutes during the entire procedure. After induction of general anesthesia, the bird was positioned in dorsal recumbency. The skin was incised approximately 15cm caudal to the caudal margin of the sternum and extended 20 to 25 cm caudally. After the proventriculotomy was peformed, the impacted material that weighed 3kg contained rocks in 4 to 6cm diameter was removed. The incision of proventriculus was closed in 2 layers. Cephalothin sodium (30 mg/kg, IV, q12hrs) and dexamethazone (2 mg/kg, IM, q24hrs) was administered before and after 5 days of the operation. The bird was eating well and defecating normal feces after 3 weeks of the surgery

Bacopa monnieri is being used in the traditional system of medicine for a variety of ailments. In the present study, the ethanolic extract of Bacopa monnieri aerial parts has been studied for its wound healing activity using various models in rats. Significant increase in wound contraction and skin breaking strength were observed in the excision and incision wound models respectively. There was also significant increase in hydroxyproline content, DNA content, superoxide dismutase activity, catalase activity, glutathione level and decrease in the level of thiobarbituric acid reactive substances in the $12^{th}$ day post wounding tissue of experimental rats in the ethanol extract treated groups with respect to the control group. The effect of the extract was found to be comparable with the standard drug nitrofurazone. From the results it may be concluded that the plant Bacopa monnieri is endowed with significant wound healing activity, thereby justifying its use in the traditional medicine. Saponins may be responsible for the observed wound healing activity.

The epicanthal fold is common natural finding in Asian eyes. It is very common that patients, who look for oriental blephaloplasty for double eye lid, request correction epicanthal fold. It is very often difficult to achieve satisfactory results if the correction of the epicanthal fold is not corrected concomitantly. Many authors described surgical procedures for correction of epicanthal folds. But most of them leave additional scars which tend to be hypertrophic and noriceable. We achieved satisfactory result in epicanthoplasty with invisible scar, using combination of procedures, such as upward incision, double eyelid operation, anchoring suture of the medial upper lid skin to the medial canthal tendon, trans-nasal root subcutaneous mattress suture of the epicanthal fold itself and combined rhinoplasty. For past six years (1998 to 2003) 17 patients have been operated with one of these mentioned procedures. The mean follow up was 4months (2weeks to 6months). All patients were satisfied and no major complication was noted. This method can be one of the effective procedures for correcting the Asian epicanthal fold for avoiding potential visible scar and ancillary procedure in double eye lid blephaloplasty.

The characteristics of the cleft lip nasal deformity is defined in this article in three planes. The alar flaring is explained in X axis, the lower positioning of the alar free margin is imagined in Y axis and the short hemicolumella is in Z axis. Most cleft surgeons have focused on the malposition of the lateral crus of alar cartilage while the author defined it in X and Y axises and tried to correct that deformity of short hemicolumella in Z axis. For the last 13 years the author applied that method in 818 cases of secondary cleft lip nose deformity. Through the columellar splitting incision extended to free margin of the alar not beyond the nasal dorsum, the skin and soft tissue of the webbing deformed the nasal tip was excised in crescent fashion. The dissected short hemicolumella including the medial crus was thus elevated and advanced into the space of the deformed nasal tip after the crescent excision. This procedure should be followed by the correction of the deformities in X and Y axis. The medial crus elevation is more effective and critical way to have the constant and nice outcome than the lateral crus reposition in secondary cleft lip nasal deformity
