The objective of this study is to establish the genotyping methods of new HLA gene, TAP1 and TAP2, and determine the genetic polymorphisms for database study in Koreans before using in clinical laboratory. Polymerase chain reaction- Restriction Fragment Length Polymorphism (PCR-RFLP) and PCR-Sequence Specific Primers (PCR-SSP) techniques were used for TAP1 and TAP2 genotying, respectively. Restriction enzymes, Bcll and Accl, and 4 oligonucleotide primers were used for the PCR-RFLP analysis of TAP1. Whereas for PCR-SSP assay of TAP2, 12 oligonucleotide primers were synthesized. The results of control cells were correlated well with the types which were analyzed at Xlth histocompatibility international workshop. Arnong three and six different alleles of TAP1 and TAP2 found in 200 unrelated Korean individuals, TAP1A (84%) was the most frequent allele. TAP1B and TAP1C were 15.5% and 0.5% respectively. TAP2A represented more than a half (55.1%). TAP2B and TAP2C were 32.2% and 9.2% respectively. TAP1D, TAP2F and TAP2G were not found in Koreans.

Total knee arthroplaty has been used to treat the elderly patient who has severe arthritis but the early designs were associated with many problems, which frequently led to early failure. In 1974, the total knee arthroplasty was introduced and the reported results of this operation have improved consistantly with time. Recently the good results has been shown to treat rheumatoid patients and osteoarthritis patients less than 45 years old patients. At the department of orthopaedic surgery of Kosin Medical College, between 1984 and 1988, total knee arthroplasty was performed in 17 patients (22 kness) who had rhematioid arthritis (7 patients) and osteoarthritis (11 patients), and had followed for an average of 1 year and 8 months. The results were as follows 1. The knee that had rheumatoid arthritis had better knee scores than that of osteoarthritis. 2. The knee that remained the post cruciate lig. had better range of motion than that sacrificed. 3. The knees that had not used cement had better knee scores than that had used the cement. 4. The knees that had patella resulrfacing had better scores for pain than that had not.

BACKGROUND: Both atrophic gastritis and intestinal metaplasia may progress to gastric dysplasia. This study aimed to analyze the factors influencing progression of atrophic gastritis and intestinal metaplasia to dysplasia. METHODS: People diagnosed with atrophic gastritis and intestinal metaplasia for the first time received a follow-up endoscopy and were investigated for the cumulative incidence rate of gastric dysplasia by age, gender, smoking habit, alcohol intake, rice consumption and family history of stomach cancer. RESULTS: The cumulative incidence rate increased with age, consuming > or =3 bowls of rice per day and family history of stomach cancer. Multivariate analysis showed that the cumulative incidence rate of gastric dysplasia increased in subjects >61 years (RR=2.54, P=0.014), in those consuming > or =3 bowls of rice per day (RR=1.46, P=0.021) and in those with a family history of stomach cancer (RR=1.31, P=0.037). CONCLUSIONS: More active management, such as intensive endoscopic follow-up examinations, lifestyle change and education regarding gastric dysplasia, are required in those older than 61 years, having a higher intake of grain or with a family history of stomach cancer.

As, until now, many studies have failed to establish the clinical effect of numerous neuroprotectives, antithrombotic therapy must be emphasized as one of critical options among limited treatment strategies in acute ischemic stroke. Based on the accumulating evidences that platelets and coagulating proteins play an important role in the thrombus formation, antiplatelets and anticoagulants are served as antithrombotics. Recently, major advances have been made in understanding the effects of antiplatelets and anticoagulants. Large randomized clinical trials have highlighted the effectiveness and safety of early and continuous antiplatelet therapy in reducing atherothrombotic stroke recurrence. Urgent anticoagulation has been used often to prevent early recurrent stroke and to improve neurological outcomes, however, its formal use in acute stroke has been the subject of debate even in cardioembolic stroke. That's because anticoagulants also increase the risk of fatal or disabling intracranial hemorrhage and it is difficult to monitor proper anticoagulation. Although early administration of anticoagulants should be considered to prevent the secondary injury and the propagation of thrombosis in patients with atherothrombotic stroke, more evidences are needed especially in patients with infractions secondary to large artery thrombosis or cardioembolism. This review discusses recent advances related to antithrombotic strategies and putative neuroprotectives.

A standardized approch to serious head injury employing immediate CT scanning and aggressive medical and surgical therapy has improved outcomes in cases of intracranial lesions. Unfortunately, there is less agreement on how patients with mild head injury should be handled when first seen in an emergency department setting. The ideal policy in mild head injury would be diagnosis or rule-out intracranial lesions as quickly as possible. We reviewed the records of 126 mild head injury patients admitted during 6-month period to the Chonnam University Hospital to identify a group of mild head injury patients having lesions on brain CT scanning and to investigate the risk factors affecting abnormal lesions on brain CT scanning. All patients had alert mental status without neurological deficit and signs of skull fracture. Routine brain CT scans were obtained on all patients. Fifteen patients(12%) had 17 lesions on brain CT scans. Three patients needed surgery for their intracranial lesions. The initial Glasgow Coma Scale(GCS) was 15 in 107 patients and 14 in 19 patients. The incidence of abnormal brain CT lesions for each GCS was 9% in 15 and 26% in 14. The common symptoms of patients who had abnormal brain CT lesions was headache in 7(47%) cases, loss of consciousness in 7(47%) cases, amnesia in 4(27%) cases, dizziness in 4(27%) cases, vomiting in 3(20%) cases, and lethargy in 3(20%) cases. These data suggest that early brain CT scanning is necessary in alert patients who have GCS in 14, headache loss of consciousness, amnesia, dizziness, vomiting, or lethargy following mild head injury.

Intracranial chondroma is a rare benign tumor. Here, we present the case of a 29-year-old female who was afflicted with left eye blindness and ptosis. Brain computerized tomography and magnetic resonance imaging revealed the presence of a giant calcified mass accompanied by a solid mass in the middle and posterior fossa. A differential diagnosis regarding chordoma, chondrosarcoma, and other chondroid tumors based on radiologic information was inconclusive. The lesion was resected completely under a microscope using a combined pterional and subtemporal approach. The pathologic report confirmed the diagnosis of chondroma. No evidence of neurological worsening was observed. The tumor had a calcified mass with mature hyaline cartilage surrounded by a thick fibrous capsule. We dissected the periphery of the tumor mass and removed it via aspiration. It was readily distinguished from normal brain parenchymal tissue. The large calcified mass at the center of the tumor had relatively high vascularity, and a high-speed drill and various rongeurs were used to remove the tumor.
