Most of malignant tumors in the urinary bladder is transitional cell carcinoma (TCC) deriving from the urothelium. Clinical stage and histopathologic grading of the TCC of the urinary bladder is important in the determination of the patient's prognosis. To investigate the correlation between the prognostic factors and the expression of the various oncoproteins and growth factors in each grade of the TCC, immunohistochemical stains for c-erbB2, c-myc, c-fos, bcl-2, p53, proliferating cell nuclear antigen (PCNA), and transforming growth factor-alpha (TGF-alpha) were performed in the formalin fixed paraffin embedded tissues of the TCC (Grade I; 15 cases, Grade II; 20 cases, Grade III; 15 cases) of the urinary bladder. The immunoexpression rate of c-erbB2 was immunoexpression 78.0% in the grade I, 85.0% in the grade II, and 95.0% in the grade III TCC. The immunoexpression rate of c-myc, c-fos and bcl-2 was below 5% in each grades of TCC. The p53 immunoexpression was identified in 11.5%, 24.3% and 30.6% of the grade I, II, and III TCC, respectively. The PCNA and TGF-alpha expression was 53.0% and 27.6% in the grade I, 77.3% and 32.7% in the grade II, and 78.2% and 37.3% in the grade III TCC, respectively. These results suggest that the expressions of c-myc, c-fos, bcl-2, and TGF-alpha are similar in each grade of the TCC and the positivity of c-erbB2, p53, and PCNA shows an increasing tendency for the higher grade TCC of the urinary bladder. Therefore, c-erbB2, p53, and PCNA are clinically useful predictors of the patient's prognosis.

3.Two Cases of Squamous Cell Carcionoma of Upper Eyelid.
Journal of the Korean Ophthalmological Society 1968;9(2_3):27-30
The authors present 2 cases of squamous cell carcinoma which occurred primarily in the eyelid. One is a 33-year-old Korean female who had the carcinoma in the right upper palpebral Conjunctiva, and the other is a 75 year-old Korean female who had the carcinoma at the margin of the left upper eyelid. These two cases were more likely to be confused with chalasion and were confirmed to be squamous cell carcinoma by the gistopathological examination.

BACKGROUND: In order to evaluate the prevalence of enterovirus and cytomegalovirus infections to terminally failing hearts, the presence of enteroviral RNA and cytomegaloviral DNA was screened in the explanted hearts of transplantation recipients. METHODS: RNA and DNA extractions were performed from explanted failing hearts (N=22) and normal hearts (N=5). Reverse transcription-polymerase chain reaction (RT-PCR) of enterovirus and polymerase chain reaction (PCR) of cytomegalovirus were performed. In situ RT-PCR and in situ PCR were performed with positive nucleic acids of viruses. RESULTS: The positivity of enterovirus in failing hearts was 4.4% (1/22) and 0% (0/5) in normal hearts in nested RT-PCR. There was no significant difference in positivity of enteroviral RNA between failing and normal hearts. Nuclei of myocardium was stained in dark-violet color with in situ RT-PCR. The positivity of cytomegalovirus in failing hearts was 45% (10/22) and 40% (2/5) in nested PCR. There was no significant difference in positivity of cytomegaloviral DNA between failing and normal hearts. Nuclei of myocardium was stained in dark-violet color with in situ PCR. Positive chambers of cytomegalovirus were in decreasing tendency according to increasing patient's age. CONCLUSION: Enterovirus was very rarely observed in explanted terminally failing hearts and cytomegalovirus was frequently found both in explanted failing hearts and normal. These viruses have little direct causal relationship with the development of heart failure.

Yoon Kyeong OH ; Keun Hong KEE
The Journal of the Korean Society for Therapeutic Radiology and Oncology 1999;17(3):203-208
PURPOSE: To evaluate whether spontaneous apoptosis has prognostic value among patients with squamous cell carcinoma of lung. MATERIALS AND METHODS: Material from 19 patients who received thoracic irradiation between 1990 and 1994 was analyzed. Their stages were II (1), IIIa (8), IIIb (5), and IV (5). Patients were observed from 5 to 67 months (median : 17 months). The spontaneous apoptosis index (AI) and p53 mutation were measured by immunohistochemical stains. RESULTS: AI was found to range from 0 to 1% (median 0.4%). Patients with low AI (AI< or =median) had a much higher distant metastasis rate at diagnosis than patients with high AI. By analysis of prognostic factors for survival, M stage was significant in univariate analysis. AI, chemotherapy, M stage, T stage, and stage were significant in multivariate analysis. The correlation between the AI and p53 mutation was not seen. CONCLUSION: AI was related with distant metastasis at diagnosis and not with p53 mutation. Also low AI group tended to have shorter survival time than high AI group.

PURPOSE: To correlate histologic subtypes with MR signal intensity in meniagioma and to find etiologic factors responsible for the signal characteristics of T2WI. MATERIALS AND METHODS: We. reviewed MRIs and histopathologic studies in 35 cases of meningioma. MR signal intenisty was measured with respect to cerebral cortex(gray matter) as hypointense, isointense, or hyperintense. Pathologically, meningioma was classified into subtypes, acording to the new WHO classification of brain tumors. The degree of cellularity, collagen, and vascularity was graded from 1 to 3, and presence or absence of psammoma bodies, microcysts, micronecrosis and microhemorrhage was obeserved. Multiple linear regression analysis was done to find relationship between the pathologic findings and MR signal intensity of T2WI. RESULTS: Even in the same subtype, cellularity, collagen and vascularty of the tumor were different. T1WI was not useful in discriminating pathologic subtype because most tumors were isointense or hypointense to the cortex regardless of histologic type. Most tumors showed various signal intensity on T2WI, but T2WI were not useful, either. Exceptionally, all five cases of microcystic meningiomas were hyperintense on T2W1. In analysing the relationship between MR signal intensity and pathologic factor, increased collagen content produced decreased signal intensity(P<0.01) and the existence of microcyst resulted in high signal intensity(P<0.01). Cellularity, vascularity, microcalcification, micronecrosis and microhemorrhage had no relationship with signal intensity on T2WI. CONCLUSION: Except for the five microcystic meningiomas with hyperintenty on T2WI there was no relationship between MR signal intensity and subtype of meningiomas. Pathologic factors influencing T2 signal intensity were microcyst and collagen. Even in the same subtypes of meningiomas, the T2 signal intensity was different. This may be due to different ratio of microcyst and collagen.

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.

Intracranial involvement by adenoid cystic carcinoma (ACC) is very rare and there is no report of intracranial extension from the palate ACC in Korea. Intracranial involvement can occur in one of three ways : direct extension, perineural spread, and hematogenous spread. A case report of a 35-year-old woman with intracranial ACC is presented. Initially she had ACC of the right palate and was treated by surgery and postoperative radiation therapy. Three years and 10 months later, the paresthesia in the distribution of ophthalmic and maxillary branch of right trigeminal nerve developed without evidence of recurrence in CT scan. Ptos and total ophthalmoplegia developed sequentially and the second operation was performed. It was suggested that the tumor was spread perineurally along the trigeminal nerve into the Gasserian ganglion and then cavernous sinus and orbit. Seven years and 6 months after the first operation, direct intracranial extension into the right temporal lobe developed via sphenoid bone, sphenoid sinus and temporal bone and the third operation was done. And then lung metastasis was diagnosed. She is alive for 9 years 5 months after first operation.

The real time high resolution mechanical neurosonographic sector scanner is a convenient and useful instrumentfor detection of intracranial lesions in premature infants as well as low birth weight. From this experience,authors report with 104 neonates and infants who had been suspected intracranial hemorrhage and had been detectedand graded by sonography. The results were as followed: 1. The incidence of intracranial hemorrhage is 20 of 46(43.5%) neonates who had been studied before 3 days of age. But 7 of 16(43.7%) neonates showed ICH between the 4-7days of age. 2. There was no difference of prevalence in sex ratio in neonates with ICH. 3. There was closerelationship between ICH and gestational weeks. 15 of 27 (55.6%) neonates who were born under 32 gestational weeksshowed ICH was graded as 3 or 4 in 7 of 10. 4. 10 of 16(62.5%) neonate who were born under 1,500 gram body weighthad ICH within first 4 days. The severity of ICH was graded as 3 or 4 in 7 of 10. 5. The mode of deliveryinfluenced neonatal ICH incase of difficulty delivery such as forcep(4/4, 100%), vacuum (7/10, 70%), breech (3/3,100%), and C/S(13/33, 39.4%). 6. Incidence of ICH in neonates with pathologica lung conditions (29/40, 72.5%) washigher than ICH with normal chest findins(15/64, 23.4%). 7. For frequent follow up study of brain, neurosonographywas very helpul and economic in case of ICH, and could find congenital glioblastoma multiformed(1), and low gradeastrocytoma(1) incidentally.
