An open trial was carried out to investigate the efficacy and tolerance of isosorbide 5-mononitrate(Elantan(R)) in 30 patients diagnosed as angina pectoris at Pusan national university hospital. Drugs were given 20mg two times daily for 2 to 3 weeks and the results were assessed in terms of effects on anginal pain and untoward side effects experienced during administration of medication. Treament resulted in an overall improvement in 25 patients(83.4%), complete abolition of anginal attacks in 17 patients(56.7%) and reduction in frequency of attacks in 8 patients(26.7%). So called "Nitrated headache" was observed in 5 patients(16.6%) but improved with proceeding of administration in 3 patients. This trial indicates that isosorbide 5-mononitrate should be efficacious as well as tolerated in patients with coronary heart disease.

OBJECTIVES: The aim of this study are clinical application of perfusion computed tomography (perfusion CT) in hydrocephalus and comparison its cerebral blood flow parameters with transcranial doppler (TCD) and clinical outcome. METHOD: 25 patients with hydrocephalus took pre- and postoperative perfusion CT and TCD. 15 patients without neurologic deficit were also examined with same protocol as a control. Blood flow parameters of perfusion CT, such as cerebral blood flow (CBF), cerebral blood volume (CBV) and mean transit time (MTT) were analyzed according to clinical status and postoperative outcome. So did the TCD parameters, mean flow velocity (mFv) and pulsatility index (PI) with regard to clinical outcome. RESULTS: Perfusion CT parameters of the hydrocephalus showed decrease in CBF (gray matter P=0.035, periventricular region P=0.042) and increase in MTT (gray matter P=0.039, periventricular region P=0.045) compared to control. In postoperative improvement group, there noted reversal of perfusion parameters close to those of the control. TCD parameters showed increase in mFv (P=0.047), and decrease in PI (P=0.042) in cases with improvement. CONCLUSION: Perfusion brain CT and TCD can used as clinically useful tools to predict the postoperative outcome on hydrocephalus.

PURPOSE: Telomerase is a ribonucleoprotein enzyme that synthesizes telomeric DNA onto the ends of chromosomes, thereby preventing the replication-dependent shortening of those ends. This enzyme is essential for stability of eukaryotic chromosomes and may be necessary for cell immortalization. Telomerase activity is detected in a wide range of cancers of various tissues, and its expression may be a critical step in tumor progression. METHODS: The telomerase activity was measured using a telomeric repeat amplification protocol (TRAP) assay in 65 cases of breast cancers, 9 cases of fibroadenomas, and 7 cases of normal breast tissues. To compare the telomerase activity with cell cycle regulators, we measured the expression of the cyclin D1 and the p53 proteins by using immunohistochemical analysis. To compare the telomerase activity with traditional prognostic indicators, we measured the ER, PR, c-erbB-2 and ki-67 expression by using immunohistochemical analysis. Disease-free survival and overall survival in relation to telomerase activity were studied by using the Kaplan-Meier method. RESULTS: Telomerase activity was detected in 42 (64.6%) of the 65 breast cancers, 4 (44.4%) of the 9 fibroadenomas, and in none of the 7 normal breast tissues. There was no significant relationship between telomerase activity and cell cycle regulators such as cyclin D1 or p53. There was no statistical correlation between telomerase activity and tumor size, lymph nodal status, or histopathological prognostic parameters, such as ER, PR, p53, c-erbB-2 and ki-67, but a significant correlation was found (p=0.006) between telomerase activity and histologic grade. The telomerase activity was not significantly correlated with either the overall survival or the disease-free survival. CONCLUSION: These results suggest that telomerasemay play a role in the malignant transformation of breast tissue and that this enzyme was more activated in cancers of a poor histologic grade. However, the telomerase activity was not related to cell cycle regulators and traditional prognostic parameters. The possible significance of telomerase activity in breast cancer remains open to further investigation.

The purpose of this study was to evaluation of occurrece and characteristics in lid lesion, all lid lesions submitted during the five- year period between March 1, 1991 and December 31.1995,were studed. There were 118 cases. The sexual distribution revealed53 males and 65 females. The mean age were 51.6-year-old. The occurrence in benign lid tumors included intradermal nevus(32 cases, 40%),chronic inflammation(9 cases, 11.3%),and seborrheic keratosis(8 cases, 10.0%). Malignant tumors were basal cell carcinoma(14 cases, 36.8%),sebaceous cell carcinoma(16 cases, 42.4%),squamous cell carcinoma(4cases, 10.5%) and malignant melanoma(4cases,110.5%),in order. From the results of this study, we hope that this report provides a basic source for diagnosis and therpy if the lid tumors.

Polypeptide growth factors belong to a class of potent biologic mediators which regulate cell differentiation, proliferation, migration and metabolism. IGF-I is polypeptides secreted by skeletal cells and is considered as regulators of bone formation. The purpose of this study is to evaluate the effects of IGF-I on bone nodule formation and alkaline phosphatase activity of MC3T3-E1 cells. MC3T3-E1 cells were seeded at 1x10(4) cells/well, 1x10(5) cells/well in alpha-modified Eagle medium containing 10% fetal bovine serum, 10 mM beta-glycerophosphate and 50microgram/ml of ascorbic acid. Before 48 hours of indicated time, medium were changed with serum free medium. After 24 hours, 0.1, 1, 10 ng/ml IGF-I were added to the cells and cultured for 3, 7, 14, 21, 28 days. And histochemical analysis was done and ALP activity was measured and was expressed as nmol/min/mg of protein. The bone nodule formation in MC3T3-E1 cells of IGF-I was seen at 21, 28 days, but there were no difference between control group and experimental groups. The ALP activity decreased when it is compare to control 2 group except for 1 ng/ml, 10 ng/ml IGF-I of 21-day-groups and 1 ng/ml IGF-I of 28-day-groups. Dose response effects of IGF-I of ALP activity in MC3T3-E1 cells were seen the highest ALP activity at 1ng/ml until 21days and the highest ALP activity at 10 ng/ml of 28 daygroups. The peak times were seen at 7-day group, 14-day group on control group and experimental group respectively, and 1 ng/ml group was the highest ALP activity. From the above results, IGF-I was not seen notable effect on bone nodule formation and decreased ALP activity of MC3T3-E1 cells but the use of IGF-I to mediate biological stimulation of MC3T3-E1 cells shows promise for future therapeutic application.

One hundred sixty three patients were hysteroscoped for various reasons at our department over 10 year period. Ninety eight patients out of 163 who were diagnosed and treated for their intrauterine adhesions(IUAs) by hysteroscopy were analysed retrospectively. Patients were classified as having mild, moderate or severe stage of IUAs according to American Fertility Society classification. Twenty nine patients(29.6%) had mild IUAs, 43 patients (43.9%) had moderate IUAs, and 26 patients(26.5%) were classified as having severe stage IUAs. The predisposing causal factors of IUAs were abortion, full-term delivery, H. mole, pelvic tuberculosis and myomectomy in order of frequency but in eight cases no cause was identified. After hysteroscopic surgery, although high rate(83.9%) of restoration of normal menstruation was attained but term pregnancy rate was only 53.3% and rather high rate (32%) of preterm or abortion were identified and those pregnancy outcomes were correlated with the stage of IUAs. Complications of surgery consisted of uterine or bladder perforation, pulmonary edema and hemorrhage.

Hypertrophic pachymeningitis is a rare disorder, with idiopathic, tuberculosis, syphilis and sarcoidosis being the most commonly considered etiology. We experienced a case of hypertrophic pachymeningitis caused by tuberculosis a 34-year old female. She had complained of consistent headache and diplopia for 20 days. The characteristic finding on magnetic resonance imaging was marked thickening of the unilateral cerebellar tentorium with gadolinium-DTPA enhancement. There was no significant changes on adjacent brain parenchyma. Histologic investigation of the left cerebellar tentorium disclosed chronic granulomatous inflammation with central caseous necrosis. The patient was successfully managed with anti-tuberculosis drugs.
