A gobiid fish , Istigobius hoshinonis (Tanaka) is described from one specimen collected at Hanrim-p, Cheju-do , on August 2, 1986. This is the first definitive record of the species in Korean waters. This species is distinguish from its congeners by the combination of the following characters ; uppermost pectoral fin ray unbranched, 12 or more predorsal scales, 7-9transverse scales and no scales on cheek and operculum. Pidan-mang-dug' is proposed as Korean name of this species.

Radiography, ultrasonography with hydrogram, and contrast studies using radiopaque markers were applied to evaluate alimentary lymphoma in two cats. The hydrogram facilitated the differentiation of pseudo-thickening from true wall thickening, and enabled an evaluation of wall layering and lymph nodes. In case 1, mechanical obstruction of the duodenum was confirmed with barium-impregnated polyethylene spheres (BIPS), a radiopaque marker; however, results obtained in case 2 were not as definitive. We expect that hydrograms and BIPS can be used as valuable alternative methods to evaluate the gastrointestinal (GI) tract although further studies in cases involving GI tumors are needed.

Between January 1990 and June 1993, the retrospective analysis was done in 48 consecutive patients with hemoptysis. According to clinical condition of patients, managements were divided into 3 subgroups; group 1[percutaneous bronchial artery embolization, group 2[operation after percutaneous bronchial artery embolization],group 3[delayed and emergency operation]. It was characterized that recurrence of hemoptysis was very frequent and most frequent underlying cause was pulmonary tuberculosis. In 40 patients[83%] urgent examination with flexible broncoscope was done and localization of the bleeding source was possible only in 24[60%] patients. The amount of hemoptysis was variable but there are no difference between groups and 22 patients[45%] had a prior episode of hemoptysis usually within 3 months of their admission. The recurrence was limited only in group 1[3/22] and the mortality rate was 6%[3/48]. We suggest that percutaneus bronchial artery embolization may be effective in recurrent massive hemoptysis but definitive management was operation.

Phlegmasia cerulea dolens (PCD) is one of the most critical disorders of acute deep vein thrombosis in that it can cause permanent disability secondary to the compartment syndrome. Although several etiological factors have been proposed, PCD after coronary artery bypass surgery is extremely rare and its definitive pathophysiology is still under debate. We herein present a case of PCD that resulted in the compartment syndrome after coronary artery bypass surgery. Early recognition and decompression of PCD are crucial for saving the affected limbs.

Leiomyosarcoma may occur anywhere in the body but rarely occurs in the heart or great vessels. Leiomyosarcoma may be managed by surgical resection with or without chemotherapy or radiotherapy. Owing to the high rate of metastasis and poor prognosis, a definitive treatment modality for leiomyosarcoma has not yet been suggested. This case study reports the surgical management of the recurrent leiomyosarcoma of the heart and the great vessels in a 63-year-old woman.

Conventional implant protocols required a load-free healing period of three to six months between placement and functional loading of the implants. Many efforts have been made to minimize the duration of treatment time. Several literatures have documented immediate function with provisional or definitive prosthesis within a week of the placement in response to these demands. In addition, immediate implant placement has advantages such as shortened treatment time and preservation of soft tissue architectures. This article presents immediate implant placement into fresh extraction sockets followed by functional immediate loading with provisional prosthesis on canine and premolars for a patient having canine protected occlusion.

Teeth that have short clinical crown, which are not alone enough to support the definitive restoration can be best treated using the post and core system. The advantages of fiber post over conventional metallic post materials have led to its wide acceptance. In addition to that the combination of aesthetic and mechanical benefits of fiber post has provided it with a rise in the field of dentistry. Also the results obtained from some clinical trials have encouraged the clinicians to use the fiber posts confidently. Fiber posts are manufactured from pre-stretched fibers impregnated within a resin matrix. The fibers could that be of carbon, glass/silica, and quartz, whereas Epoxy and bis-GMA are the most widely used resin bases. But recently studies are also found to be going on for polyimide as possible material for the fiber post resin base as a substitute for the conventional materials.

Rupture of the esophagus is an uncommon condition that can be a formidable challenge to treat. Unless early treatment is applied, life-threatening complications, such as mediastinitis, sepsis, occurs and continue to be associated with a mortality rate of more than 20%. Definitive repair of esophageal perforation is considered the preferred treatment in the past. In the present study, conservative treatment acquired a good results by help of the development of antibiotics and nutritional supportive methods. Iatrogenic causes constituted most of the injuries, followed by external trauma, spontaneous, ingested foreign bodies, and malignancy. The incidence of perforation following ingestion of foreign bodies is very rare, so recommendations regarding treatment remain controversial. We analyzed the course of 31 patients with esophageal perforation by foreign bodies, concentrating on the diagnostic & treatment delay and methods of treatment, complications.

Korea has rapidly increased R&D investment over the last few decades and the intensity of R&D investment is among the highest in the world; however, there are serious concerns about R&D performance and R&D efficiency. This study is to improve the economic assessment methodology regarding a feasibility study for national R&D programs that are thought to be one of the most prominent ways to enhance R&D efficiency. In order to improve the methodology of economic assessment, a few of important factors such as technical or market uncertainty, spillover effect, and R&D contribution ratio should be covered in the model. The focus of this article is technological and market uncertainty that has a close relation with strategic flexibility and utilization potential to increase the value of R&D programs. To improve the current linear and definitive R&D process, a new framework with strategic flexibility is suggested, in which the result of economic assessment that considers technological and market uncertainty is reflected in planning. That kind of feedback process is expected to enhance the value of the program/project as well as R&D efficiency.

Objectives: This study aimed to review the general features of drug induced liver injury (DILI) and the important factors in consideration of herbal drugs and DILI. Methods: We reviewed general aspects of DILI such as classification, inducible factors, diagnosis methods, prevention, and the status of herbal drug-associated DILI via literature. Results: Besides the drug itself, genetic and environmental factors affect hepatic toxicity. There is a lack of definitive diagnoses of DILI by drugs, including herbal remedies. The possibility of herbal drug-associated DILI is exaggerated, and majority of herbal drug-derived hepatic injury could be easily prevented if Oriental doctors pay attention to this issue. Conclusion: This study can provide Oriental doctors an overview and be helpful in minimizing the episodes of hepatotoxicity in use of herbal drugs.
