  • To obtain information about the structure of the human phenylethanolamin N-methyltransferase (PNMT) and to further define the extent of the evolutionary relationships among PNMT molecules of several spesies, a full length cDNA clone for bovine adrenal PNMT was used to screen a charon 4A genomic library. One phage was isolated and identified, which included the entire PNMT gene. The length of inserted genomic DNA was 13.1-Kilobase (Kb) containing two internal EcoRI sites. Construction of a restriction map and subsequent Southern and dot blot analysis with 5'-and3'-specific cDNA probes allowed the identification of exon-containing fragments. This is the first report of the cloning of gene for human epinephrine synthesizing enzyme.

  • Objective : Two famous medical doctors, Yoo Itae(以泰, 爾泰) and Riu Euitae(義泰), have been well known in academic world and public in Sancheong-gun. Yoo Itae is the progenitor of Majinhak which is the therapy for measles, he wrote a "Majinpyun" as the first book of therapy for measles in Chosun. Riu Euitae, meanwhile, is a fictional medical doctor and a teacher of Heo Jun who became real without confirmation of historical truths by Roh Jeongwoo who heard about a name, Yoo Itae. Roh's assertion was quoted in the report of literatures, papers, novel, and telecast without verification. His assertion is exposed in novel and media and it has seriously distorted the history. The purpose of this study is to rectify the historical distortion. Methods : Various references study was performed. Confirmed a family tree, birth and death year, birthplace, sepulture, words on a tombstone, writing, collections of works anthology and the existence of keepsake. Investigated records of royal family, Sancheong-gun papers, Sancheong Hyanggyo papers, Dongyuhagan, Chosun Hanryuseungram and the record of Sawoo Munjip(anthology). Analyzed Roh Jungwoo's conversation that tells Riu Euitae is a teacher of Heo Jun and contents of an encyclopedia. Listened to testimony of descendants and assertions of historian in rural area. Verified voice recording on books taken from at birthplace and the space of activity. Results : Yoo Itae is well shown in various records and medical writing books, whereas Riu Euitae does not. Riu Euitae is not a real person in the history. Roh Jeongwoo who asserts Riu Euitae is a teacher of Heo Jun admits his mistake. But, the encyclopedia record describing Riu Euitae is a teacher of Heo Jun, government official at Sancheong district office, historians in rural area, historians in rural area who made a family shrine, gravestone, a statue, memorial, historic site of Riu Euitae on Jinju Rui could not suggest any evidences for the existence of Riu Euitae and for record Riu Euitae is a teacher of Heo Jun. Conclusion : Riu Euitae is neither a real person in the history nor a teacher of Heo Jun. Riu Euitae came from pronunciation confusion between 'I' and 'Eui' in Kyungsang province. Riu Euitae is Yoo Itae on Geochang Yoo who was a medical doctor of King, Sukjeong and wrote medical books including , , .

  • Kaposi's sarcoma was first descrided by Kaposi in 1872 as an idiopathic multiple hemorrhagic sarcoma. Its clinical features revealed to be erythematous red or purple macule started out, and developing into palpable dome-shaped nodules. Etiology is not defined to detail at present. Kaposi's sarcoma is classified to 4 categories; Classical, African, Epidemic and Immunosuppressive type. Epidemic categories is found approximately 20% of all AIDS patients and has strong predilection for head and neck region. The first case of immunosuppresive type Kaposi's sarcoma in patients with kidney transplants was reported in 1969. Kaposi's sarcoma accounts for 5% of all tumors associated with transplanted patients. The most common site of Kaposi's sarcoma in immunosuppressed patients are extremities, but rare in head and neck area. A 42 years old woman who had systemic lupus erythematosus visited to our clinic because of gingival hyperplasia, and excisional biopsy revealed Kaposi's sarcoma. We experienced a case of favorable results using excision and chemotherapy, so we report with review of literatures.

  • Burning mouth syndrome(BMS) refers to a chronic orofacial pain disorder usually unaccompanied by mucosal lesions or other clinical signs. Tongue(anterior and lateral border) is found to be the most common site for the burning sensations in the oral cavity, and various oral sites may be affected including hard palate and lips. The etiology of this disorder remains poorly understood, but the various factors might be related with the pathogenesis of the BMS. These factors have been devided into local, systemic and psychological. Recently, there have been increasing reports that the pain of BMS may be neuropathic in origin. The complex and multifactorial etiology of BMS necessitates multidisciplinary approach for the management of these patients. Recently, several studies have reported that oral parafunctional habits could be related the pathogenesis of BMS, and tried to control the symptom of BMS with various methods. We reported the cases who had the symptom of burning mouth syndrome with removable anti-nociceptive appliance in the lower dentition.

  • Arthroscopic anterior cruciate ligament(ACL) reconstruction using four-strand hamstring tendon with looping around transfixing screw in femoral tunnel requires osteointegration between the grafted tendon and bone for stability of the knee. Authors have experienced a histologic finding of osteointegration between the grafted autogenous hamstring tendon and bone in femoral tunnel after arthroscopic ACL reconstruction. A patient received arthroscopic ACL reconstruction with autogenous four strand hamstring tendon for the ACL injury. Traumatic re-rupture of mid-substance of ACL graft was developed at thirteenth week after operation. During the procedures of arthroscopic revision at fifteenth week after initial ACL reconstruction, biopsy was performed at the site of interface between grafted tendon and bone in femoral tunnel. Integration between the grafted tendon and bone was evident by demonstrating the continuity of collagen fiber between bond and tendon. This histologic finding and the low incidence of early graft failure suggest that free tendon autograft attached to bone by looping around a transfixing screw in femoral tunnel undergoes adequate osteointegration between 12 and 15 weeks after surgery and authors thought that insertion of bone chip into the femoral tunnel would accelerate osteointegration procedure.

  • Implant-fixed prostheses and removable partial dentures are widely used as a traditional treatment method for partially edentulous patients who have lost multiple teeth. Recently, there has been increasing interest in implant-assisted removable partial denture (IARPD), which additionally obtains retention and support using a small number of implants. The IARPDs have higher retention, stability, and aesthetics than conventional removable dentures. It also has the effect of reducing the cost as well as the burden of surgery by placing a small number of implants at the edentulous site. In this case, the patient with a partial edentulous state that has multiple numbers of tooth loss in maxilla initially planned to be treated with implant fixed prosthesis. However, the treatment plan was changed to IARPD using Bar and Locator due to several factors. The clinical results were satisfactory on the aspect of esthetic and masticatory function.

  • In the case of the impacted teeth, the clinician has to consider development of tooth, site of impaction, eruption path, and cooperation of patient. If there are genetic or general factors to effect the eruption of tooth, the clinician treats these first and then takes the early treatment for eruption guidance. If there are physical factors to intercept eruption, the clinician put them off first. However, if there are no factors to effect eruption of tooth and enough space for eruption, the clinician can consider extraction of deciduous teeth, forced eruption and surgical reposition. In case of surgical repositioning, proper time for root development, proper socket formation, and minimal trauma are important for success. This case presents displaced impacted maxillary central incisor with dilacerated root. The development of root is Nolla's stage 7, and the tooth was treated by surgical repositioning. We can observe no root resorption and good healing pattern.

  • Stem blight symptom of soybean was severely developed in 2016 in Hwaseong and Yeoncheon. During the seedling period, the damping-off of seedlings and the brown or black spots of cotyledons were observed. After August, the leaves began to be yellowed, and partially browned areas on leaves began to develop. After September, microsclerotia began to form even on the surface of the stems that had exhibited water-soaking symptom. After mid-October of the harvest season, the epidermis of the stem was peeled off, resulting in the formation of a large number of microsclerotia in the cortex. The pathogens isolated from these symptoms were the best in mycelial growth at 32-35℃, and the formation of microsclerotia was the most at 20-28℃. The pathogen was identified as Macrophomina phaseolina through the morphological characteristics of the pathogen and the sequencing of the internal transcribed spacer region gene. In addition, when inoculated with a soybean stem using toothpicks cultured with the pathogen, the same symptoms as seen on the soybean field occurred. When the pathogen was re-isolated at the lesion site, the same pathogen was isolated and identified as Macrophomina phaseolina. Based on the results, the disease is reported as soybean charcoal rot.

  • Osteosarcoma is the most common tumor in malignant bone tumors. The peak age incidence in osteosarcoma is between 10 to 14 years of age. This tumor rarely develops under 6 years of age and the youngest patient in the previous literature was a 13 months old girl who had an osteosarcoma involving the second metacarpal bone. We report a case of an 8 month old male infant, who had an osteosarcoma involving the right proximal tibia. This patient was treated by wide excision with transepiphyseal resection and reconstruction with allograft. At 20 months after operation, the varus deformity was developed at the proximal junctional site of allograft. Thereafter, the revision was performed with correction of deformity and augmentation with the proximal fibula transfer. At 51 months after operation, he has been remained as free of disease, and he has recovered the knee motion ranged from 15 degree to 75 degree. The osteosarcoma in infant is very rare but it should be considered the osteosarcoma in the differential diagnosis of any bone lesion. Instead of amputation, the limb sparing operation and the solutions for limb length inequility in growing period should be carefully considered in the infantile osteosarcoma.
