Hypertensive choroidopathy is seen in patients suffering from acute ypertension such as pregnancy-induced hypertension, renal disease, connective tissue disease, and accelerated essential hypertension, which can affect the visual acuity in many ways. Especially, retinal detachment is the most important factor in visual prognosis, so understanding its clinical course is important to the ophthalmologist. We diagnosed the 257 severe preeclampsia and eclampsia patinents at the Soonchunhyang University Hospital from January 1987 to Auguest 1996, and found 19 cases of serous retinal detachment. The fluorescein angiography showed delayed perfusion of the choriocapillaris in the earlyphase and marked pooling of dye in subretinal space in the late phase. The results of this study revealed that serous retinal detachment occured mostly binoculary (83.3%); the extent of the pathologic region ranged from 2.11DD to 7.2DD (mean 4.06DD); total bullous retinal detachment was found in one case; the duration of reattachment ranged from 8 to 43 days (mean 9.95days); and the recovery interval of visual acuity was between 21 to 35 days(average interval 18.5 days). Of 12 cases followed up 11 cases showed normal visual acuity, normal visual field and retinal reattachment without the macular degeneration.

We performed a clinical observation on the 208 cases of infectious hepatitis who were cared at the pediatric department of Fatima Hospital from July, 1, 1970, to June, 30, 1977, and obtained the following results. 1. The ratio of infectious hepatitis to the total number of in-patients was 3.25 in average. 2. There was no significant difference in seasonal incidence except spring when the incidence was lower than the other seasons. 3. The age-group of 3~8 years old occupied 69% of the total cases and sex incidence revealed mali predominence with the ratio about 2:1. 4. The frequently observed clinical manifestations included ; Anorexia(71%)Nausea/Vomiting(65%), Tiredness(53%), Dark urine(59%), Abdominal pain(54%), Fever(45%), Jaundice(75%), Hepatomegaly(71%), Tenderness on upper adbomen(40%), and Palpable spleen(12.3%). 5. In the most of the cases the hematologic findings were with-in normal limit. 6. Bilirubinuria was observed in about 65% of the tested cases during the first 2 weeks of the illness and urinary urobilinogen was decreased during the second week of the illness. 7. In the majority of the cases the serum bilirubin reached peak during the second week of the illness and ranged 2~15mg%. And by the end of the 4th week illness, they returned to less than 2mg% in the 85%of the tested cases. 8. SGOT and SGPT reached peak during the first week of the illness and by the end of 4th week, they returned to less than 100 unit in the most the tested cases. And the values of SGOTwere higher than SGOT throughout the course of the illness. 9. The electrophoresis of the serum protein revealed as follow ; 1-globulin decreased slightly and -globulin in creased. 10. We experienced 30 cases (14.4%) of anicteric hepatitis. 11. ABHg was positive in 2(3.8%) of the 52 tested cases. 12. 10 of the 208 cases complicated hepatic coma and 10 of them expired and 3 of them dischared without clinical improvement.

According to the reports, the prevalence of anti-HCV is about 1%. In past, the results of the prevalence of HBs Ag & HBs Ab in the patients of Hansen's disease were reported. But we don't know about that of anti-HCV. So we study about the prevalence of serum anti-HCV of 60 patients & PALS of Hansen's disease. And we test about Alk. Phosp., ALT, AST, Gtlc HBs Ag & HBs Ab. 1. The prevalence of anti-HCV is 8.33%. It is higher than past reports(about 1-2%). 2. The prevalence of HBs Ag is 3.4% & that of HBs Ab is 36.3%. 3. Because of the high prevalence of anti-HCV in the patients of Hansen's disease & PALS, we think that more studies are need about it.

Preadipocyte cell lines are useful models for investigating adipogenesis process. 3T3-L1 preadipocyte, which can be induced to differentiate into adipocyte in cell culture, is one of the most studied preadipocyte cell lines. When exposed to the appropriate differentiation inducer, including insulin, dexamethasone and 3-isobutyl- 1-methylxanthine, 3T3-L1 preadipocytes differentiate into adipocytes. This study was undertaken to evaluate the effect of epigallocatechin on differentiation of 3T3-L1 preadipocyte, and to test whether epigallocatechin can be useful to reduce fat deposition. Cell proliferation was determined by MTT(3,4,5-Dimethylthiazol-2,5-Diphenyl- Tetrazoliumbromide) spectro-photometry, fat content followed by cell differentiation was determined by Oil Red O staining, and the degree of differentiation into adipocytes were determined by measuring mRNA content and activity of glyceraldehydes 3-phosphate dehydrogenase (G3PDH). Epigallocatechin inhibited proliferation of preadipocytes, not into adipocytes. Fat storage during 3T3-L1 preadipocyte conversion into adipocyte was inhibited by epigallocathechin. Epigallocatechin decreased G3PDH, leptin mRNA and peroxisome proliferator-activated receptor(PPAR)gamma mRNA which were increased by differentiation of preadipocyte into adipocyte. These results suggest that epigallocatechin has a potential to serve as a fat-reducing drug.

PURPOSE: Free cancer cells exfoliated from cancer-invaded serosa contribute to peritoneal dissemination, the most frequent pattern of recurrence in patients with gastric cancer. To detect free cancer cells, CEA and CA19-9 were introduced as the markers of gastric cancer, and many methods, such as cytology, immunoassay, and reverse transcription polymerase chain reaction (RT-PCR), exist for detecting them. The aim of this study is to define the clinical significance of using immunoassay to measure the levels of CEA and CA19-9 in the peritoneal washings in patients with gastric cancer. MATERIALS AND METHODS: The peritoneal washing fluids were obtained from 130 patients with gastric cancer who received a curative gastrectomy, palliative gastrectomy or open and closure. The pCEA and pCA19-9 levels were measured by using immunoassay and cytology. The results were compared with the clinicopathological data. RESULTS: The pCEA and pCA19-9 levels were correlated with tumor invasion, lymph-node metastasis, and stage (P<0.05). CONCLUSION: A correlation was found between elevated pCEA and pCA19-9 levels measured by immunoassay and the TNM stage. Therefore, a combined pCEA and pCA19-9 assay could be a sensitive detector of peritoneal dissemination, as well as a predictor of postoperative prognosis. pCEA and pCA19-9 may also determine the adjuvant management strategy.

BACKGROUND AND OBJECTIVES: Cardiac troponins are associated with increased mortality, even among patients with no coronary artery disease. Elevated cardiac troponin levels are frequently observed in patients without significant coronary lesions, although the mechanism underlying this finding is unclear. The aim of our study was to evaluate the association between the levels of cardiac troponin and coronary flow reserve (CFR). SUBJECTS AND METHODS: We evaluated serum cardiac troponin-I in 19 patients (9 female; age 61.9+/-10.9 year-old). All patients had an ejection fraction >40% and angiographically normal coronary arteries. Simultaneous measurements of fractional flow reserve (FFR), the index of microcirculatory resistance (IMR), and CFR measurements using an intracoronary temperature- and pressure-sensing guidewire under basal conditions and during maximal hyperemia were performed in three vessels: the left anterior descending artery (LAD), left circumflex artery (LCX) and right coronary artery (RCA). RESULTS: All patients were followed for a median of 13 months. FFR, IMR, and CFR measurements were performed successfully in all subjects. Mean CFRs of LAD, LCX, and RCA were 1.98+/-1.20, 2.75+/-2.11, and 4.44+/-2.51, respectively. Mean IMRs of LAD, LCX and RCA were 33.28+/-18.78, 29.11+/-26.70, and 30.55+/-23.65, respectively. There was a poor correlation between CFR and troponin-I values in each vessel. In selecting the lowest value of CFR in each patient as the corresponding value, the lowest CFR was not associated with troponin-I levels (r=-0.219, p=0.367). CONCLUSION: In patients without significant coronary lesions, the correlation between CFR and troponin-I level was not significant using a thermodilution technique. Further study of a larger population with longer-term follow-up may be needed to more fully understand microvascular dysfunction.

A 38-year-old woman with twin pregnancy was referred after detection of hydrocephalus in one fetus at 23+1 weeks' gestation. Sonography showed hydrocephalus, a scalloping of the frontal bone giving a lemon-like configuration, and meningocele. The affected twin was terminated by ultrasonographically guided intracardiac injection of 4 ml (8 mEq/L) potassium chloride solution at 24+5 weeks' gestation. Chromosomal analysis of the other fetus showed normal findings (46, XX). Serial ultrasound scans and coagulopathy tests were unremarkable. Preterm premature rupture of the membrane was developed at 33+3 weeks' gestation, and emergency Cesarian section was done. A healthy 1360 g female was born, with Apgar scores of 7 and 8 at one and five minutes, respectively.

Various venous approaches are available for chemoport insertion. The subclavian vein and jugular vein are commonly used. The cephalic vein has several advantages for chemoport insertion. The authors introduce chemoport insertion using cephalic vein. Operation methods were as follows: patient was placed in supine position. Under local anesthesia, the incision was made in the infraclavicular portion, dissection was performed along the deltopectoral groove and the cephalic vein was identified and isolated. Dissection was performed between the subcutaneous fat layer and the muscle layer to make space for chemoport placement. The cephalic vein was incised and the catheter was introduced to the cephalic vein directly and examined by fluoroscopy. Chemoport insertion using cephalic vein is a useful method of chemoport insertion.
