Soft denture liners or conditioners may be valuable therapeutic materials. The life of these liners is short and varies, but it can be extended by the use of a mono-poly(polymethyl methacrylate coating material). This study determined whether coating three temporary soft denture liners with mono-poly affected the resiliency of soft liners, and evaluated the ability of mono-poly to prevent water absorption and alcohol loss from the underlying soft liners. 20x12mm cylindrical specimens of Coe-Soft, Soft-Liner, Coe-Comfort soft lining materials were made and divided into two groups of mono-poly uncoated(control) and mono-poly coated specimens. Specimens were immersed in water and compressed on an instron universal testing machine and weighted at initial, 24 hours, 1 week, 2 weeks, and 4 weeks. resiliency was determined by measuring the energy absorbed by the soft liners when stressed to a specific yield point. Mono-poly coating significantly increased the resiliency of the Soft-Liner, but had no effect on the other soft liners. Among the 3 soft liners, Soft-Liner showed the hightest resiliency and modulus of elasticity. The weight loss in Soft-Liner was the least among the 3 liners, and the weight loss in Coe-Soft was decreased by monopoly coating.

BACKGROUND: Headache is a common symptom. It has not proved useful methods that the physician evaluated the alert patient who had headache. It needs the presence of predictors of intracranial pathology(ICP) which serves as influential factors in the indication of evaluation and hospitalization of patients. METHOD: So, in order to identify such factors, patient records were retrospectively analysed. 168 patients with the chief complaint of headache presented to the Emergency Department of Chonnam University Hospital during the period from January 1, 1995 to December 31, 1997. All were in an alert mental state and had no evidence of trauma and intoxication. RESULTS: 14 cases(8.3% revealed ICP. 41 cases(24.4% revealed systemic disease. The remainder of cases were divided among unclassified headaches(61 cases, 36.3%, tension headaches(30 cases, 17.9%, and migraine(22 cases, 13.1%. Comparison of ICP-positive and ICP-positive cases revealed that ICP-Positive Patients could be categorized by the following findings: (1) Presence of the focal sign through neurological examination, (2) age greater than 55 years, (3) presence of associated symptoms, (4) acute headache. These four manifestations were proven to be statistically significant as predictors of ICP. CONCLUSION: Although the positive predictive value of the above criteria is not perfect for the prediction of ICP, they are worthy of clinical consideration in alert patients presenting with headache.

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.

BACKGROUND: To investigate how many rookie pitchers suffered from injuries while playing in the amateur league without guidelines for prevention of excessive pitching, we analyzed their amateur pitching patterns based on the pitch count, use of breaking balls, and pitches during winter camp. METHODS: Forty-one rookie pitchers who graduated from high school or university in 2013 and joined professional baseball teams. Participants were interviewed by a trainer using our questionnaire. Injury inclusion criteria were 1) history of shoulder surgery, 2) history of elbow surgery, 3) shoulder pain requiring treatment, and 4) elbow pain requiring treatment. RESULTS: Mean number of pitches per game and warm-up pitches for practice was 84.5 pitches (range, 15 to 130 pitches) and 16.4 pitches (range, 2 to 210 pitches), respectively. Mean number of pitches during the last year was 906.9 (range, 80 to 2,000). Mean number of maximal pitches was 127 pitches (range, 50 to 210 pitches). Fourteen pitchers had pitched over 150 pitches. Twenty-seven pitchers (65.9%) had pitched in spite of enduring pain. During winter training (mean 1.8 months), mean number of pitches per day was 162.5 pitches, and 20 pitchers (48.8%) had practiced pitching excessively despite the cold weather. Twenty-six rookies (63.4%) had shoulder pain or history of shoulder surgery, and 31 pitchers (75.6%) had elbow pain or history of elbow surgery. Only four participants (9.8%) did not have pain and history of surgery. CONCLUSIONS: For young baseball pitchers, guidelines for prevention of excessive pitching and for regulating the winter training program may be needed.

BACKGROUND: ST segment elevation in patient with chest pain was seen in acute myocardial infarction and in numerous other non-infarction syndrome. The causes of non-infarction syndrome were left ventricular hypertrophy, BER(benign early repolarization), and left bundle branch block in cardiac origin and were hyperkalemia and hyperventilation syndrome in metabolic origin and were others. Furthermore, the differentiation of electrocardiogram between acute myocardial infarction and non-infarction syndrome was very difficult. So, we compared and analysed characteristics of ST segment elevation of acute myocardial infarction and non-infarction syndrome that suggested the clue of early diagnosis of coronary artery disease. METHOD AND MATERIALS: We retrospectively reviewed the electrocardiogram of 961 patients with chest pain who visited the emergency center from January 1999 to December 1999. Acute myocardial infarction was diagnosed by clinical finding, electrocardiogram, cardiac enzyme, echocardiogram, and myocardial spect. Left ventricular hypertrophy, BER, and left bundle branch block in cardiac origin of non-infarction syndrome were diagnosed by electrocardiographic criteria suggested by William J. Brady. Acute myocarditis, acute pericarditis, and hyperventilation syndrome were diagnosed by clinical finding. RESULTS: Among 961 patients with chest pain, 236(24.6%) patients manifested ST segment elevation who were diagnosed acute myocardial infarction in 162(68.6%) patients and non-infarction syndrome in 74(31.4%) patients. The causes of non-infarction syndrome in 74 patients were left ventricular hypertrophy(32:13.6%), BER(28:11.9%), left bundle branch block(11:4.7%), and others(3:1.3%). Three others were acute myocarditis, acute pericarditis, and hyperventilation syndrome. Electrocardiographic characteristics of ST segment elevation of non-infarction syndrome manifested almost same finding compared to William J. Brady' criteria. CONCLUSION: ST segment elevation in patient with chest with chest pain visited emergency department was seen in acute myocardial infarction(68.6%) and the other non-infarction syndromes(31.4%). Significant number of patients were not associated with acute myocardial infarction. Therefore, we must completely understand characteristics of ST segment elevation in acute myocardial infarction and the other non-infarction syndromes to diagnose fatal early coronary artery disease and to avoid unnecessary thrombolytic therapy.

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.

Growth under conditions of iron-restriction and the production of siderophore was examined in Vibrio mimicus ATCC 33653. This strain grew and multiplied in the presence of the high-affinity iron chelators ethylenediamine-di (o-hydroxyphenylacetic acid). Chrorne azurol S (CAS) agar and solution were used to detect the production of siderophore under these condition. Siderophore could be detected in the iron-rcstricted culture supernatants. The siderophore was extracted from iron-restricted culture supernatants by phenol-chloroform-ether method and purified by Dowex ion-exchange and Sephadex G-25 gel filtracton chromatography. The purified siderophore was confirmed by paper chromatography and HPLC. The Purified siderophore enhanced the growth of V. mimicus when the bacterium was grown in iron limited medium. Injection of both the siderohore and the bacteria to mice resulted in more rapid death than that of the only bacteria. However, the siderophore did not show lethality to mice and any toxicity to cell line like HeLa and U937.
