Specific diagnosis of orthopedic disease can be diffcult in canine practice. Failure to detect the clinical signs of a disorder during physical examination of dogs with acute or chronic lameness is the most common reason for failure to make specific diagnosis. A 6-month-old, female doberman with history of swelling and non-weight-bearing lameness in the left forelimb was referred to Beterinary Teaching Hospital of Chungbuk National University. Physical examination, plain radiography, and conventional three-phase radionuclide bone scan were performed in the patient. Based on the physical exam and radiography, this case was diagnosed as elbow strain and subluxation. Conventional three-phase bone scan detected soft tissue inflammation and osteochondral lesions of elbow joint, and revealed good agreement with clinical findings. Therefore, conventional three-phase bone scan was able to provide the precise information about inflammation of soft tissue and osteochondral lesions of joint.

We report a case with dysphagia for solids. A 51-year-old man with benign esophageal stricture was transferred for endoscopic treatment. He had lye ingestion history at 9 years old and underwent esophagectomy with right colonic interposition for the treatment of the benign esophageal stricture. But his symptom was acting up 2 years ago and lasted afterward even though he had underwent endoscopic treatments for dysphagia several times, including balloon dilation and stent insertion. He had polypoid enhancing wall thickening around anastomosis site of stomach with perigastric soft tissue density and suspicious nodular extension to omentum on the small bowel computed tomography. So he had a surgical resection of small bowel and jejunojejunostomy, and the pathological result was adenocarcinoma, intestinal type with soft tissue infiltration. Later he underwent total gastrectomy with segmental resection of interpositional colon and segmental resection of duodenum and ileo-colic anastomosis revision. And recently he has been on chemotherapy.

Erwinia rhapontici causes soft-rot disease in a number of plants such as onion, garlic and hyacinth. There has been no report that E. rhapontici produces pectate lyase. Pel gene was cloned from genomic DNA of the parasitic soft-rot E. rhapontici polymerase chain reaction by using synthetic oligonulceotide primers designed from the pel 1 to E. carotovora. The recombinant plasmid pJE101 containing pectate lyase gene, when introduced into E. coli DH5$\alpha$, produced pectate lyase an macerated hyacinth tissue.

Alveolar soft part sarcoma, named by Christopherson in 1952, is a very rare soft tissue sarcoma. It reportedly accounts for 0.5 to 1.0% of all soft tissue sarcoma and no established treatment principle assists it. The relative lack of symptoms makes it easily overlooked and consequently early diagnosis is frequently impossible. Often, the metastasis to the lung or the brain is the first manifestation of the disease. In some cases wide excision is not performed because it is misdiagnosed as a benign tumor. Authors experienced 7 cases of alveolar soft part sarcoma in 20 years and found the ultimate prognosis grave and the treatment not promising. Therefore, the authors recommend the following; 1. Early diagnosis and early treatment are important for successful management of alveolar soft part sarcoma. 2. Preoperative incisional biopsy is necessary for pathologic diagnosis. 3. The recommended treatment modality is a combination of wide excision, chemotherapy and radiotherapy.

On April of 2000 and February of 2001, a disease characterized by darkening, ascites and enlargement of the spleen occurred in flounder, Paralichthys olivaceus, farmed near northern and eastern coasts of Korea. Various degree of necrosis including liquefactive-type was observed mainly in hemopoietic tissue of spleen and kindney. Certain tissue such as branchial soft tissue including epithelium showed a similar necrotic findings. But some tissues such as intentine had several necrotic clusters of wandering cells, being possibly leukocytes. Necrotic evidences of blood cells were evident in various tissues including hemopoietic tissues. Necrobiotic bodies were frequently encountered in blood smear preparations. Bullet type-virious were detected in the spleenic cells. Each virion was about 500 nm in diameter and 170nm in length. From these results, this disease was thought to be a rhabdoviral disease.

배추 무름병을 대상으로 식물병원균 감염모델을 확립하기 위하여 무름병변을 가진 배추조직으로부터 80개의 독립된 세균집락을 순수 분리하였다. 이들 균을 감염되지 않은 배추 잎의 주맥부위에 접종하여 24${\sim}$48 시간 만에 무름병변을 나타내는 8개의 균주를 1차 선별하였다. 다양한 미생물학적, 생화학적, 형태학적인 시험을 통하여 분석한 결과 서로 다른 특성을 나타내는 균이라고 여겨지는 3개의 균을 최종 선정하였고 이들은 모두 그람 음성균으로 판명되었고 RB1, RB2 및 RB6로 명명하였다. API 20E시험, VITEK 2 COMPACT 분석, 16S rRNA 염기서열 분석 등을 종합할 때 RBl 및 RB2는 Erwinia carotovorum subsp. odoriferum 아종으로, RB6는 Erwinia carotovorum subsp. carotovorum 아종으로 추정되었다. 이들 균들은 $30^{\circ}C$, 생리적 pH인 중성 pH에서 최적생육을 하였다. 이들은 배추의 상처 유무에 상관없이 초기 접종양과 비례하여 무름병을 유발하였으며, 상처가 없는 경우보다 상처가 있는 경우에 더욱 명확한 병변을 유발하였다. RBl의 경우 $8.0{\times}10^8$ CFU/ml, RB2 균주는 $10^9$ CFU/ml, RB6는$4.7{\times}10^6$ CFU/ml에서 최초로 무름 증상을 나타냈다. 이들 균의 숙주 특이성을 관찰하기 위하여 14종의 야채에 접종한 결과 배추, 가지 파프리카에서만 무름병변을 유발하는 숙주 특이성을 나타내었다. 이 연구에서 사용된 실험재료들 및 감염모델은 향후 식물병원균의 감염기작해석에 크게 기여할 것으로 예상된다.

Background: Soft-tissue sarcomas require tailored and multidisciplinary treatment and management. However, little is known about how sarcomas are treated and managed throughout the Asia-Pacific region. Materials and Methods: MEDLINE was systematically searched using prespecified criteria. Publications (previous 10 years) that reported tumour characteristics, treatment patterns, survival outcomes, and/or safety outcomes of patients with soft-tissue sarcoma were selected. Exclusion criteria were studies of patients <18 years of age; ${\leq}10$ patients; countries other than Australia, Hong Kong, Indonesia, Korea, Malaysia, New Zealand, Philippines, Singapore, Taiwan, or Thailand; >20% benign tumours; sarcomas located in bones or joints; gastrointestinal stromal tumour; Kaposi's sarcoma; or not reporting relevant outcomes. Results: Of the 1,822 publications retrieved, 35 (32 studies) were included. Nearly all patients (98%, 1,992/2,024; 31 studies) were treated with surgery, and more studies used adjuvant radiotherapy than chemotherapy (24 vs 17 studies). Survival outcomes and recurrence rates varied among the studies because of the different histotypes, sites, and disease stages assessed. Only 5 studies reported safety findings. Conclusions: These findings highlight the lack of specific data available about soft-tissue sarcomas in the Asia-Pacific region. Better efforts to understand how the sarcoma is managed and treated will help improve patient outcomes in the region.

Purpose: The purpose of this study was to preliminarily evaluate the influence of diabetes mellitus (DM) on periodontal tissue without establishment of periodontitis. Methods: Seven-week-old db/db mice were used for the diabetic experimental group and systematically healthy mice of the same age were used as controls. After 1 week of acclimatization, the animals were sacrificed for hard and soft tissue evaluation. The pattern of bone destruction was evaluated by stereomicroscope evaluation with alizarin red staining and radiographic evaluation by microscopic computerized tomography images. Histological evaluation was performed with hematoxylin and eosin stain for evaluation of soft tissue changes. Results: In both stereomicroscope evaluation and radiograph image analysis, aggressive form of bone destruction was observed in diabetic animals when compared to the systematically healthy controls. In histological evaluation, apical migration of junctional epithelium with slight inflammatory cell infiltration was observed with disarrangement of connective tissue fibers. Conclusions: Within the limits of this study, diabetic animals presented distortion in periodontal attachment and an aggressive bone loss pattern when compared to the healthy controls, suggesting that DM has an independent effect on periodontal tissue destruction irrespective of the presence or absence of periodontal disease.

Purpose Surgical correction of various occular problems which do not have visual problem in plastic surgical area is to normalize the appearance of the face by restoring the normal position of orbit and eyeball. With development of surgical technique, the orbit can be restored exactly in trauma patient and can be moved totally in hypertelorism, as an example of congenital disease. All these surgeries are based on the hypothesis that the position of oclular glove moves in the plane in a quantitatively predictable reationship to osseous orbit movement. However, no studies have critically evaluated between the change of periorbital soft tissue and the outcome of the surgical correction, because there is no method of objective, quantitave evaluation of the periorbital soft tissue. Method Author suggest the methodology for quantitative assessment of ocular and periocular fat changes using the manipulation of digital images of computed tomographic scan. Results The method was allowed to evaluate inter-dacryon distance, inter-centroid distance, movement of the medial orbital wall, movement of the lateral orbital wall, alteration of thickness of the lateral periorbital fat as indicator of movement of the orbital wall and orbit in the patient with congenital periorbital anomaly and postoperative periorbital surgery. The goal of surgical correction of various occular problems which do not have visual problem in plastic surgical area is to normalize the appearance of the face by restoring the normal position of orbit and eyeball. With development of surgical technique, the orbit can be restored exactly in trauma patient and can be moved totally in hypertelorism, as an example of congenital disease. All these sugeries are based on the hypothesis that the position of oclular glove moves in the plane in a quantitatively predictable relationship to osseous orbit movement. However, no studies have critically evaluated between the change of periorbital soft tissue and the outcome of the surgical correction, because there is no method of objective, quantitave evaluation of the periorbital soft tissue. In this report, author suggest the methodology for quantitative assessment of ocular and periocular fat changes using the manipulation of digital images of computed tomographic scan. Conclusion The method suggested is objective and accurate method in measurement of the orbital contents. It takes time and is not easy to do, however, this kind of measurement for fine structures will be more easily available in near future.
