The 5 year-survival rates were examined to evaluate the prognositic significance of the expression of the p53 protein and the positivity of the PCNA in 108 cases of advanced gastric carcinoma. The p53 protein and PCNA were stained by immunohistochemistry in the tissue of the gastrectomized specimen. The results were as follows. 1) The overall 5 year-survival rate of advanced gastric carcinoma was 42.3 % and the significant prognostic factors were a pathologic stage and p53 protein(p<0.005). 2) The expanding or infiltrating type by Ming's classification and the intestinal or difftise type by Lauren's classification had similar prognosis. 514_ @@l %R-t 3) The 5 year-survival rate of the p53-positive group was 25.1% and that of p53-negative group was 56.1%(p<0.005). 4) The 5 year-survival rate of the PCNA low-grade tumors by PCNA stain(<50%)was 48.7% and that of the high-grade tumor(>=50%)was 29.9%(p>0.1). 5) There was a tendency to have a good prognosis in the p53-negative group and low grade tumors in the stage 11, III, and IV. There was a significant difference between p53 protein positive and negative groups in the stage III(p<0.005), but no significant differences were found in the other groups. The above results indicate that the p53 protein is an another useful tool for prediction of the prognosis in advanced gastric carcinoma.

BACKGROUND: Antibiotic therapy has proven an effective method of treatment on the majority of patients with pyogenic lung abscess and infected bulla. When medical therapy has failed, pulmonary resection is the current generally recommended therapy. But nowdays complications of percutaneous tube drainage has decreased with the use of small catheter. So we evaluated the effect of percutaneous tube drainage as an alternative therapy to the pyogenic lung abscess and infected bulls refractory to medical therapy in preference of the pulmonary resection. METHOD: Nine cases of the lung abscess and three cases of infected bulls which has large cavity size over 6cm, and has underlying diseases such as lung cancer, diabetes mellitus, refractory to over 1 week of antibiotics, were performed percutaneous tube drainage with All Purpose Drainage catheter(Medi-tech, Watertown, USA) under fluoroscopy. RESULTS: All the cases except one case which complicated empyema was improved clinically. Fever was down within 4days of percutaneous tube drainage(mean : 1.9days). Mean duration of tube drainage was 9.9days. CONCLUSION: Percutaneous tube drainage is an effective and relatively safe procedure in the management of lung abscesses that do not response to medical therapy We speculate this procedure should be considered as an alternative therapy for the lung abscess refractory to medical therapy in preference to the surgery. The safety and effectiveness of this procedure in infected bulla should be evaluated with an additional study.

All-ceramic restorations have become an attractive alternative to porcelain-fused-to-metal crowns. In-Ceram, and more recently IPS Empress 2 were introduced as a new all-ceramic system for single crowns and 3-unit fixed partial dentures. But their strength and marginal fit are still an important issue. This study evaluated the fracture resistance and marginal fit of three systems of 3 unit all-ceramic bridge fabricated on prepared maxillary anterior resin teeth in vitro. The 3 all-ceramic bridge systems were: (1) a glass-infiltrated, sintered alumina system (In-Ceram) fabricated conventionally, (2) the same system with copy-milled alumina cores (copy-milled In-Ceram), (3) a heat pressed, lithium disilicate reinforced glass-ceramic system (IPS Empress 2). Ten bridges of each system with standardized design of framework were fabricated. All specimens of each system were compressed at 55degree at the palatal surface of pontic until catastrophic fracture occurred. Another seven bridges of each system were fabricated with standard method. All of the bridge-die complexes were embedded in epoxy resin and sectioned buccolingually and mesiodistally. The absolute marginal discrepancy was measured with stereomicroscope at x50 power. The following results were obtained: 1. There was no significant difference in the fracture strength among the 3 systems studied. 2. The Weibull modulus of copy-milled In-Ceram was higher than that of In-Ceram and IPS Empress 2 bridges. 3. Copy-milled In-Ceram (112micrometer) exhibited significantly greater marginal discrepancy than In-Ceram (97micrometer), and IPS Empress 2 (94micrometer at P=0.05. 4. The lingual surfaces of the ceramic crowns showed smaller marginal discrepancies than mesial and distal points. There was no significant difference between teeth (incisor, canine) at P=0.05. 5. All-ceramic bridges of three systems appeared to exhibit sufficient initial strength and acceptable marginal fit values to allow clinical application.

PURPOSE: To evaluate the usefulness, patterns and appearances of false positive lesions, and technical problems of CTAP(CT Arterioportography). MATERIALS AND METHODS: CTAP was done in 45 patients in whom hepatic lesions were suggested on other radiologic studies. CTAP findings were compared with the informations obtained by operations, biopsies, and follow-up imagings. Additional findings, which were not detected in other radiologic studies, false positive manifestations, and technical errors were analyzed. RESULTS: CTAP detected 51 additional hepatic lesions which are not detected in other imaging studies. Of the 51 lesions, ten were true positive hepatic tumors, 2 were inflammatory lesions and 39 were false positive .lesions. False positive lesions included perfusion defects of periportal and perifissural areas, subcapsular perfusion defects and nonlobar, nonsegmental geographic perfusion defects. In 2 cases, CTAP aided in deciding the surgical strategy. On the other hand, there were 4 cases causing interpretational confusion and 6 cases of improper imaging due to technical errors. CONCLUSION: CTAP was valuable in detection of additional hepatic cancer lesion as well as in making the treatment plan. However, since many false positive lesions and improper imaging due to technical error occur during the examination, the understanding of such problems is essential for correct interpretation of CTAP.

A 4-year-old boy has had a solitary sclerotic depressed plaque on the right anterior chest since birth. The histopathologic findings are consistent with morphea profunda: thickening, hyalinization, and homogenization of collagen bundles in the dermis and subcutaneous tissues, admixture with a prominent lymphocytic and plasma cell infiltrate, and sweat glands en-trapped between the thickened collagen bundles. We report a case of congenital solitary morphea profunda.

Usually the histologic response of muscle to the ischemia range from mild, reversible change to extensive necrosis and fibrosis in the case of anterior tibial compartment syndrome. But dystmphic calcification in the late stages is very rare condition.Only three cases were previously reported by Gallie and Broder et al in the literature. We are reporting six cases of dystrophic calcification following anterior tibial compartment syndrome in late stages. Onsets of dystrophic calcifications after original injuries ranged from twelve years to thirty-two years. Two out of six cases revealed painless maas in the anterior tibial compartment and remaining four cases revealed painful aases. At surgery, tooth-paste like, calcified material was evacuated in one of five operated cases and yellowish grey, brittle materials were evacuated in the remaining four cases.

The purpose of this study was to compare the fracture resistance of copy-milled and conventional In-Ceram crown. Four groups of ten uniform sized all-ceramic crowns were fabricated. In-Ceram Spinell and In-Ceram Alumina crowns were fabricated as control group, Celay In-Ceram Spinell and Celay In-Ceram Alumina crowns were fabricated as test group. All specimen were cemented on stainless steel master die with resin cement, and stored in 37degrees C water for 1 day prior to loading in Instron testing machine. Using a steel ball at a crosshead speed of 0.5mm/min, the crowns were loaded at 30degree angle until catastrophic failure occurred. The results obtained were as follows : 1. With the value of 984.8N+/-103.67N, the strength of Celay In-Ceram Alumina crowns had a significantly higher fracture strength than conventional In-Ceram Alumina crowns(876.2N+/-92.20N) (P<0.05). 2. The fracture strength of Celay In-Ceram Spinell crowns(706.3+/-70.59N) was greater than that of conventional In-Ceram Spinell crowns(687.4+/-90.26N), but there was no significant difference(P>0.05). 3. The In-Ceram Alumina crowns had a significantly higher fracture strength than In-Ceram Spinell crowns in both methods(P<0.05). 4. Ther order of fracture strength was as followed : Celay In-Ceram Alumina, In-Ceram Alumina, Celay In-Ceram Spinell and In-Ceram Spinell crowns

The discovery of C-T scan have facilitated the detection of post-traumatic hydrocephalus cases. Of those, 6 cases of hydrocephalus of non-parenchymatous in origin, in other words, normal pressure hydrocephalus were presented. They were diagnosed by repeated brain C-T and cisternography with Iodine 131-labeled human serum albumin. The symptomatology, diagnosis procedure and surgical results were discussed. Followings are the results. 1) The RIHSA cisternogram taken after 6 hrs, 12 hrs, 24 hrs and 48 hrs from lumbar injection showed abnormal features in all cases. 2) Surgical results were thought that there is much correlation with the age and improvement of mental impairments were seen, more or less, in all cases and improvement of gait disturbance and incontinence were seen in 5 cases and 4 cases respectively. 3) In those who sustained severe head injury with delayed recovery, the authors think, repeated check of brain C-T and cisternography is necessitated to perform the V-P shunt or V-A shunt to relieve the symptomatology of normal pressure hydrocephalus.

BACKGROUND: Motion sickness is one of the major problems of aerospace medical concern. Vestibule plays an important role in giving rise to motion sickness. Drugs preventing motion sickness have a suppressive effect on the vestibular function through the antagonistic effect to some receptors in vesibular nuclei and vomiting center of central nervous system. We identified and quantified the effects of anti-motion sickness drugs on vestibule-ocular reflex in healthy human subjects. METHODS: Fourty-five healthy male subjects were grouped to one of placebo, dimenhydrinate 50 mg, scopolamine (1 patch), or both scopolamine and dimenhydrinate group, and received rotation chair test before and after drug administration to obtain Vestibulo-ocular reflex (VOR) gain and phase in sinusoidal harmonic acceleration (SHA) with frequencies of 0.01, 0.02, 0.04 and 0.08 Hz. The delta gain and the delta phase by the drug administration were obtained and analyzed as pharmacodynamic effects. RESULTS: Baseline gain and phase data were not different by the groups in all SHA frequencies. VOR gains were significantly decreased by 0.15~0.17 after dimenhydrinate administration. In the scopolamine group, there were significant decreases in 0.04 and 0.08 Hz by 0.14 and 0.15, respectively, but no difference in 0.01 and 0.02 Hz was observed. Increasing tendency in VOR phase lead was observed, especially in dimenhydrinate, but not significantly. There was no additive effect on the reduction of VOR gain when the two drugs were co-administered. CONCLUSION: We quantitatively characterized how much the VOR parameters were changed by the drugs with different kinds of mechanism. Dimenhydrinate reduced the VOR gain by around 0.16. However, scopolamine probably has a minimal or no additive effect on VOR suppression.
