The purpose of this study is to verify severity of asthma in asthmatic patients through through the arterial blood gas analysis. Subjects were consisted of 103 patients (74 boys and 29 girls), between 2~13 years of ages. Clinically, asthmatic patients were classified into 6 groups, i, e., group 0(no rhonchi), group 1(rhonchi only), group 2(mild attack), group 3(moderate attack), group 4(severe attack), group 5(respiratory failure with disturbance of consciousness). PH kept normal range in the group 0, group 1, group 1 and group 3,but began decrease in the group 4.There was linear fall in Po2 and began decrease in the group 3. HCO3- maintained normal level through the whole range. BE showed acidemia on the whole, and began distinctive decrease in the group 4 and group 5, especially. Hypoxemia, hypercapnia and acidemia were common in patients in severe attacks with disturbance of consciousness.

STATEMENT OF PROBLEM: Regardless of any restoration, most of case, we used in screw connection between abutment and implant. For this reason, implant screw loosening has been remained problem in restorative practices. PURPOSE: The purpose of this study was to compare surface of coated/plated screw with titanium and gold alloy screw and to evaluate physical property of coated/plated material after scratch test in FESEM investigation. MATERIAL AND METHODS: GoldTite, titanium screw provided by 3i (Implant Innovation, USA) and TorqTite, titanium screw by Steri-Oss (Nobel Biocare, USA) and gold screw, titanium screw by AVANA (Osstem Implant, korea) - were selected for this study. Each abutment screw surface was observed at 100 times, and then screw crest, root, and slope were done more detailed numerical value, at 1000 times with FESEM. A micro-diamond needle was also prepared for the scratch test. Each abutment screw was fixed, micro-diamond scratch the surface of head region was made at constant load and then was observed central region and periphery of fine trace through 1000 times with FESEM. RESULTS: The surface of GoldTite was smoother than that of other kinds of screw and had abundant ductility and malleability compared with titanium and gold screw. The scratch test also showed that teflon particles were exfoliated easily in screw coated with teflon. Titanium screw had a rough surface and low ductility. CONCLUSION: It was recommended that the clinical use of gold-plated screw would prevent a screw from loosening.

DNA aneuploid cells are poorly characterized in both biochemical and morphological terms. This study was performed to see the relationship between DNA ploidy and morphometric and photometric nuclear features. DNA contents of tumor cells were measured by image cytometry in 46 cases of micro- or early invasive squamous cell carcinoma of the uterine cervix. Also measured were nuclear area, perimeter, maximum diameter, chromatin pattern index, and staining intensity. Among the 46 cases, 20 cases which had both DNA diploid and aneuploid cell subpopulations were selected, and the two subpopulations were discriminated statistically. Multivariate discriminant analysis seperated clearly the two subpopulations, whereas univariate analysis failed. For canonical discriminant function, nuclear area was selected first, followed by staining intensity in each case. Other variables selected afterwards were nuclear perimeter, maximum diameter, and/or chromatin pattern index in random fashion. Correlation coefficient between the canoncial discriminant function and the variables were 0.20~0.40 for nuclear area and 0.25 or less for the others. The above results suggest that DNA ploidy is a parameter more or less independent on individual morphometric and photometric parameters.

Thirteen cases of lengthening of short tubular bone by gradual axial distraction using an unilateral external fixator(Orthofix M-100, Orthofix CP0089) are reported. This study aims to prove effective- ness of gradual distraction for lengthening of short tubular bone and usefulness of the newly designed external fixator. Nine patients had brachymetatarsia and four brachymetacarpia. The etiology was consisted of post-traumatic physeal injury in two and congenital in eleven cases. The average amount of lengthening was 14.5mm(37.0%) in metacarpal bone, and 17.3mm(37.5%) in metatarsal. Complications were angular deformity in 3, pin loosening in 2 cases, and premature consolidation, nonunion and pin site infection in one case, respectively. Cosmetical and functional satisfactory results were obtained in all cases. We believe that callotasis is effective for short tubular bone lengthening. Also we confirmed the newly designed external fixa- tor(Orthofix CP0089) useful.

Indefinite-for-neoplasia is an expression used to describe lesions in which carcinoma or dysplasia cannot be clearly and conclusively established via biopsy. Gastric indefinite-for-neoplasia may represent a reactive change secondary to inflammation in some patients; however, some lesions are eventually diagnosed as dysplasia or carcinoma. Follow-up endoscopic biopsy is commonly performed in patients with gastric indefinite-for-neoplasia lesions. Nonetheless, patients may undergo resection based on a high index of clinical suspicion for dysplasia or carcinoma based on endoscopic findings. Accurate target biopsies of the lesion and effective communication with pathologists are required to improve diagnostic accuracy and avoid unnecessary re-examinations. It is important to establish endoscopic findings useful in differentiating lesions that require resection. In this review, we describe the approach for the management of indefinite-for-neoplasia lesions detected on gastric mucosal biopsy and the characteristics of lesions that require resection.

To investigate personality characteristic of dry eye patient, an investigation on objective personality characteristics of 41 dry eye syndrome patients was performed with MMPI (Minnesota Multiphasic Personality Inventory). Of 41 patients tested, 14 (34.1%)patients had at least one MMPI clinical scale more than 70 point of T-score, abnormality greater than 70 point of T-score occurred most frequently in the scales for ypochondriasis, psychasthe-nia, depression, hysteria, social introversion.In the group profile study, mean T-scores on each clinical scale were within normal range, and the highest scales in rank order were hypochondriasis, depression, psychasthenia. In the relation between results of TBUT and Schirmer test and T-scores of each clinical scale, correlation coefficient is insignificantly low (r0.4). Therefore we recommend comprehension of their emotional condition and an additional psycholgical management with classical treatment as dry eye syndrome management.

BACKGROUND: The Cobra Perilaryngeal Airway (CobraPLA) and the Laryngeal Mask Airway (LMA) Classic are supraglottic airway devices. We compared the performance of the CobraPLA and the LMA Classic devices during volume-controlled ventilation in children. METHODS: Eighty children, ASA physical status I-II, aged 1-10 years were randomly assigned with either the CobraPLA or the LMA Classic for airway management. Anesthesia was induced with 1 mg/kg ketamine and 2.0 mg/kg propofol, and muscle relaxation was obtained with the use of 0.5 mg/kg rocuronium. All patients were mechanically ventilated with a tidal volume of 10 m/kg in 1-3% sevoflurane, oxygen and air. The number of insertions, oropharyngeal leak pressure, and fiberoptic airway position were measured. Measurements of blood pressure, heart rate, oxygen saturation, end-tidal carbon dioxide, and peak inspiratory pressure were recorded every 5 minutes. Postoperative adverse events were assessed. RESULTS: There was no significant difference between the use of the two devices with respect to the number of insertions, time of insertion, and fiberoptic score. The oropharyngeal leak pressure was significantly higher for the CobraPLA than the LMA Classic (25.4 +/- 4.9 cmH2O versus 20.3 +/- 5.4 cmH2O; P < 0.001). Hemodynamic and respiratory variables were similar with the use of both devices. The incidence of adverse events was not different with the use of both devices. CONCLUSIONS: Both airway devices provided an adequate airway and effective ventilation during volume-controlled ventilation in children. The CobraPLA had a higher sealing pressure than the LMA Classic.

OBJECTIVES: The objective of this study is to measure and to compare the rate of depression, anxiety, self-esteem and the quality of life of the patients with chest pain. Based on the result of this study, the necessity of the psychiatric assessment and treatment of the patients with chest pain is emphasized. This study is a preliminary research for a larger scale investigation to be carried out in the future. METHODS: Thirty nine patients with chest pain who visited Cardiovascular Division of Dept. of Internal Medicine Pusan National University Hospital and fourty normal control group(NC) were included in this study. The patients were classified into typical chest pain group(TCP, N=19) and atypical chest pain group(ACP, N=20) based on the cause of the pain. The cause was determined by cardiac computed tomography, exercise stress test, coronary angiography, and questionaires by a cardiology specialist. The patients were assessed with Beck Depression Inventory(BDI), State-Trait Anxiety Inventory(STAI), Rosenberg Self-Esteem Scale(RSES) and Korean version of the Smith Klein Beecham 'Quality of Life' scale(KvSBQOL). RESULTS: 1) When the risk factors of cardiac disease is compared, most of the factors(Hypertension, Diabetes, Hyperlipidemia, Cerebral infarction) did not differ significantly among the two chest pain groups, except for the family history, for which TCP group showed higher risk than ACP group did. 2) As for the self-report questionaires scores, BDI score, which indicates the rate of depression, of both ACP group and TCP group was significantly higher than that of NC group in BDI for depression. STAI score, which measures anxiety, was also significantly high in both groups. Especially, STAI score was significantly higher in ACP group than TCP group. 3) In the aspect of self-esteem and quality of life, ACP group scored significantly lower than TCP group and NC group. The scores for TCP group and NC group did not differ significantly. CONCLUSIONS: The patients with chest pain showed more depression and anxiety than normal control group, regardless of the cause of the pain. However, TCP group did not show significantly larger drop in self-esteem and quality of life than ACP group did. This result implies that early psychiatric assessment and treatment is needed for the patients with such chest pain, since it is highly likely that the pain would lead to lower quality of life of the patients.
