Reactive human mesothelial cells were examined by immunocytochemical stain with intermediate fiiaments (cytokeratin [CK1, CK7, CK8, CK18, CD19], vimentin, desmin, actin), epithelial membrane antigen, carcinoembryonic antigen (CEA), MHC class II antigen (HLA-DR), LeuM-1 (CD15), alpha1-antitrypsin(ACT), alpha1-antichymotrypsin(ACMT), CD68(KP-1) and FcyRIII(CD16). The mesothelial cells were isolated from patients with liver cirrhosis and pleural effusion, and short-term cultured in RPMI 1640 media containing 10% heat inactivated fetal calf serum and 1% identical supernatant fluid of the patients transudates. The results obtained are as follows. 1. The cultured-reactive mesothelial cells were positive for the protein of cytoskeleton such as cytokeratin and vimentin, but negative for desmin and actin. The resting mesothelial cells showed positive reactions for cytokeratin, but negative for vimentin, desmin and actin. 2. The primary antibodies to the cytokeratin were strongly reactive for CK1, CK8 and CK18 but negative r CK7 and CK19 in both reactive and resting mesothelial cells. 3. Resting mesothelial cells showed negative reactions for CEA, but strong positive reactions in cultured-reactive mesothelial cells. 4. The markers for the monocytes/histiocytes(CD11b, CD14, CD16, CD68, lysozyme and alpha1-antitrypsin and alpha1-antichymotrypsin) were nonreactive in resting mesothelial cells, but lysozyme and alpha1-antitrypsin were weakly reactive in reactive and proliferative mesothelial cells. 5. MHC Class II molecule(HLA-DR antigen) was negative in both resting and reactive mesothelial cells. These results suggest that the short-term cultured, reactive mesothellal cells show a newly aberrant expression of the vimentin and carcino-embryonic antigen. The reason of the aberrant expression of the intermediate filament and oncofetal antigen in reactive and proliferative mesothellal cells should be further evaluated.

OBJECTIVE: Moyamoya disease (MMD) is an uncommon cerebrovascular disorder, characterized by progressive occlusion at the terminal portion of the internal carotid artery. Incidence of the disease is high in East Asia and familial MMD accounts for about 15% of the disease. Although the pathogenesis is unknown, association of HLA class I or II alleles with MMD has been reported with conflicting results. We investigated whether there is a difference in HLA class II association between familial and non-familial forms of the disease. METHODS: A total of 70 Korean children with MMD, including 16 familial cases (10 probands), and 207 healthy controls were studied. Among familial cases, only 10 probands were used for the HLA frequency analysis. High resolution HLA-DRB1 and DQB1 genotyping was performed using polymerase chain reaction (PCR)-sequence specific oligonucleotide hybridization and PCR-single strand conformation polymorphism methods. RESULTS: The phenotype frequencies of HLA-DRB1*1302 (70.0%) and DQB1*0609 (40.0%) were significantly increased in familial MMD compared to both controls [vs. 15.5%, corrected p (pc) = 0.008, odds ratio (OR) = 12.76; vs. 4.3%, pc = 0.02, OR = 14.67] and non-familial MMD patients (vs. 14.8%, pc = 0.02, OR = 13.42; vs. 1.9%, pc = 0.02, OR = 35.33). The frequencies of DRB1 and DQB1 alleles in non-familial MMD patients were not significantly different from those in controls. CONCLUSION: Our findings suggest that the genetic polymorphism of HLA class II genes or other closely linked disease relevant gene(s) could be a genetic predisposing factor for familial MMD.

BACKGROUND: Propofol and ketamine had been used for anesthesia induction and for total intravenous anesthesia. The nature of any hypnotic interactions occurring between propofol and ketamine are unknown. A comparison of maternal and neonatal effects among propofol-ketamine combination, ketamine and propofol were studied when used for anesthesia induction in Cesarean section. METHODS: Forty five patients in ASA class I or II scheduled for Cesarean section randomly assigned to either propofol 2 mg/kg (n=15), ketamine 1 mg/kg (n=15) or propofol 1 mg/kg - ketamine 0.5 mg/kg combination group (n=15) as an induction agent. Maternal systolic and diastolic blood pressure, heart rate, Apgar score and umbilical blood gas analysis were measured. RESULTS: Before intubation, systolic and diastolic pressure were decreased in propofol group but increased in ketamine and propofol-ketamine combination group. Heart rate were increased in all three groups. But there were no significant differences among three groups (p<0.05). After intubation, there were significant increase in systolic, diastolic pressure and heart rate in three groups but no significant differences among three groups (p<0.05). And there was no significant neonatal depression as assessed by Apgar scores and blood gas analyses. CONCLUSIONS: Propofol-ketamine combination was found to be similar to propofol or ketamine only in the effects on the mother and neonate. But propofol-ketamine gained more stable hemodynamic change than propofol or ketamine before intubation. Therefore propofol-ketamine appears to be a suitable alternatives to propofol or ketamine as an induction agent for anesthesia in Cesarean section.

An asymptomatic 26-year-old man was initially admitted with a suspicious mediastinal mass. On the basis of the contrast-enhanced chest CT findings, aneurysm formation involving the left cervical aortic arch associated with subaortic left innominate vein was diagnosed. The aneurysm was confirmed by MR angiography and DSA. The arch aneurysm was surgically removed. We describe this case, and review the literature.

PURPOSE: To compare the Hong's grading method, utilized for slit-lamp grading of the mid-peripheral angle, with other conventional grading methods. Actual angle was measured by ultrasound biomicroscopy (UBM) for comparison. METHODS: Fifteen eyes with narrow angles and eighteen eyes with wide angles were studied. The average age of thirty-three subjects was 46.8+/-19.2, and the male to female ratio was 1:3.7. The mid-peripheral angle was graded by Hong's, van Herick's and Spaeth's grading system. The actual anterior chamber angle was evaluated by UBM and the correlation between each grading system and actual angle was investigated. RESULTS: The results from the Hong's grading (r=0.802, R2=0.643, p<0.01), Spaeth's grading (r=0.728, R2=0.530, p<0.01) and van Herick's grading (r=0.618, R2=0.382, p<0.01) methods correlated significantly with the actual angles. CONCLUSIONS: The Hong's grading method was an easy and effective tool to evaluate anterior chamber angle. In addition, the results of the Hong's grading method were closer to the actual angle than the other methods.

BACKGROUND: Evaluation of clinical performance is an essential area of Medical Licensure Examination. Yet, clinical skills has been neither uniformly well taught nor adequately assessed. This study was done as a part of preliminary study to introduce clinical performance assessment to Korean Medical Licensure Examination. The goals of this study were to identify the potential logistic problems and to examine the feasibility of OSCE to Medical Licensure Examination. METHODS: 48 minutes long OSCE, which consist of eight 5-minute stations, was developed. The same examination was administered to students over a four-week period. RESULTS: Total 26 volunteer fourth-year medical students were tested. 11 students were examined at the first administration and the rest of them were evaluated four-week later. Cronbach alpha of the total stations was 0.52. Any big administration problems were not revealed. There was no significant total score difference between early examinee and later ones. Students evaluated the OSCE contents and process positively. CONCLUSION: To acquire more reliable and valid examination, we need to develop more objective checklist and evaluator and SP training.

BACKGROUND: Calcium plays a key role in vascular contraction and regulates receptor sensitivity to certain neurotransmitters. Calcium channel blockers are useful in the treatment of both clinical and experimental hypertension. The present study was designed to examine whether there is an alteration of the activity of calcium channels in association with the development of hypertension. METHODS: Deoxycorticosterone acetate(DOCA)-salt hypertension was made by subcutaneous implantation of DOCA(200mg/kg)strip plus saline drinking(1%) and 2-kidney, 1 clip(2KIC)hypertension by clipping the left renal artery with a silver clip(internal gap of 0.2mm). They were used 4 weeks later. Age-matched normal rats served as a control. Mean arterial pressure(MAP) and heart rate(HR) were continuously recorded from the right femoral artery. The drugs were administered intravenously. RESULTS: Vehicle alone was without effect on MAP or HR. In normotensive rats, nifedipine infusion(5 and 10ug/kg/min)caused a dose-dependent decrease in MAP without significant changes in HR, while Bay k 8644(Bay K, 5 and 10 ug/kg/min) increased MAP transiently. Both the depressor response to nifedipine and the pressor response to Bay k were more marked in DOCA-salt hypetensive rats than in normotensive rats. The maximal changes in MAP indced by nifedipine(5 and 50 ug/kg) or Bay K(5 and 50 ug/kg) were also enhanced in 2KIC hypertensive rats as compared with control rats. CONCLUSION: These results indicate that calcium channel inhibitors and activators can affect on the regulation of blood pressure in an opposite fashion. It is also suggested that the activity of calcium channels might be altered in the developement of experimental hypertension.
