Background: Residual pleural thickening (RPT) is the most frequent complication of tuberculous pleurisy (TP), and this can happen despite of administering adequate anti-tuberculous (TB) therapy. Yet there was no definite relation between RPT and other variables. The aim of this study was to examine matrix metalloproteinases (MMPs) and the inhibitors of metalloproteinases (TIMPs) and to identify the factors that can predict the occurrence of RPT. Methods: The patients with newly-detected pleural effusions were prospectively enrolled in this study from January 2004 to June 2005. The levels of MMP-1, -2, -8 and -9, and TIMP-1 and -2 were determined in the serum and pleural fluid by ELISA. The residual pleural thickness was measured at the completion of treatment and at the point of the final follow-up with the chest X-ray films. Results: The study included 39 patients with pleural fluid (PF). Twenty-three had tuberculous effusion, 7 had parapneumonic effusion, 7 had malignant effusion and 2 had transudates. For the 17 patients who completed the anti-TB treatment among the 23 patients with TP, 7 (41%) had RPT and 10 (59%) did not. The level of PF TIMP-1 in the patients with RPT ($41,405.9{\pm}9,737.3ng/mL$) was significantly higher than that of those patients without RPT ($29,134.9{\pm}8,801.8$) at the completion of treatment (p=0.032). In 13 patients who were followed-up until a mean of $8{\pm}5$ months after treatment, 2 (15%) had RPT and 11 (85%) did not. The level of PF TIMP-2 in the patients with RPT ($34.4{\pm}6.5ng/mL$) was lower than that of those patients without RPT ($44.4{\pm}15.5$) at the point of the final follow-up (p=0.038). Conclusion: The residual pleural thickening in TP might be related to the TIMP-1 and TIMP-2 levels in the pleural fluid.

In order to use the excellent features of saponin and phenolic compounds in the leaf and fruit of ginseng, ginseng fruit Yakgwa (GFY), ginseng leaf Yakgwa (GLY) and ginseng root Yakgwa (GRY) were made via adding the fruit, leaf and root powder in the process of making Yakgwa, and the properties were investigated. When making Yakgwa, GFY and GLY had superior expansion compared to GRY. 2.5-GFY (added 2.5% ginseng fruit powder) and 2.5-GLY (added 2.5% ginseng leaf powder) increased about 1.68 times and had better expansion than the control; however, when more amount of fruit and leaf were added, the expansion was decreased. The GFY and GLY showed green and red color, and the brightness and yellowness were decreased. Oil absorption during making Yakgwa showed to increase as the amount of fruit and leaf powder were increased regardless of the ginseng parts. Hardness of Yakgwa increased as the root additives were increased, and it decreased when leaf and fruit were added. The results of sensory evaluation on ginseng-based Yakgwa showed that oily taste was lowered as the amount of fruit and leaf additives were increased, which had increased the preference. On the overall preference of Yakgwa, 5.0-GFY, 2.5-GLY and 7.5-GRY was high, which contained 2.30 mg/g, 1.02 mg/g, and 0.91 mg/g of saponin, respectively.

Dopamine(DA), norepinephrine(NE), and epinephrine(E) belong to a class of neurotransmitters known as catecholamine (CA) which are synthesized and secreted by mammalian brain and adrenal medulla. CA regulate several behavior patterns connected with breeding, and regulate GnRH-gonadotropin hormone axis' vitality between hypothalamus-pituitary gland linking with reproduction freeze. The present study examined effects of sex steroid hormone on the transcriptional activities of CA biosynthesis enzymes, tyrosine hydroxylase(TH), dopamine $\beta$ -hydroxylase(DBH), and phenylethaolamine-N-methyl transferase(PNMT). Mature female rats were ovariectomized(OVX) and implanted with 17 $\beta$-estradiol(E$_2$: 500 $\mu\textrm{g}$/ml) or sesame oil. Forty-eight hours after implantation all the animals were sacrificed. Total RNAs were extracted immediately and were applied to semi-quantitative reverse transcription-polymerase chain reaction(RT-PCR). The expression level of TH was appeared by hypothalamus > SNc> adrenal medulla orders in OVX＋Oil group, and by SNc > hypothalamus) adrenal medulla orders in OVX+E$_2$ group. Treatment with E$_2$ significantly increased TH expression in SNc and adrenal medulla but in hypothalamus, the reduced TH expression was observed. The expression level of DBH was appeared by adrenal medulla > SNc > hypothalamus orders in OVX＋Oil group and in OVX＋E$_2$ group. Administration of E$_2$ significantly reduced DBH expression in SNc, and increased in adrenal medulla. Two cDNA products, large(PNMT1) and small(PMNTs) species of 110bp difference, were amplified in SNc and hypothalamus, but only PNMTs was observed in adenal medulla. The PNMTs expression level was in the order of adrenal medulla > hypothalamus > SNc in both OVX＋Oil and OVX＋E$_2$ group. The PNMTs expression in SNc and adrenal medulla was significantly increased byE$_2$. The present report demonstrated that estrogen effects on transcriptional activities for CA biosynthethic enzymes were tissue specific in adrenal medulla as well as different region of brain. These results suggest that it might be crucial relationship between the type of estrogen receptor and CA enzyme gene expression.

The objective of this study was to improve the flavor of Cheonggukjang prepared by the culture optimization of starter with the fibrinolytic activity. After 25 strains isolated from the commercial Cheonggukjang and Doenjang in different regions were compared, 7 Bacillus strains with proteolytic and slime-producing activities were selected. When the fibrin plate method for fibrinolytic activity was applied, CJJN-4 and 5 showed the higher activity in tripticase soy broth (TSB). All Cheonggukjang prepared with CJJN-4 and 5 also had the fibrinolytic activity, regardless of culture temperature or time. Especially, Cheonggukjang prepared at $40^{\circ}C$ showed higher activity than $45^{\circ}C$, and Cheonggukjang prepared with CJJN-4 for 48 hr at $40^{\circ}C$ showed the highest fibrinolytic activity. Although there was no significant difference in pH of Cheonggukjang prepared with CJJN-4 or 5 during 72 hr at $40^{\circ}C$, Cheonggukjang prepared with CJJN-4 at $45^{\circ}C$ had lower pH until 60 hr than $40^{\circ}C$ or CJJN-5. The total amino type nitrogen contents of Cheonggukjang were 1,139.6 (CJJN-4) and 1,027.6 mg% (CJJN-5) for 72 hr at $40^{\circ}C$, and their producing rates were also higher at $40^{\circ}C$ fermentation than $45^{\circ}C$. Meanwhile, the contents of ammonia type nitrogen induced unpleasant flavor were lower in Cheonggukjang with CJJN-4 and 5 at $40^{\circ}C$ than CJJN-5 at $45^{\circ}C$. Therefore, Cheonggukjang fermented with CJJN-4 starter at $40^{\circ}C$ had the improved flavor, such as change of amino or ammonia type nitrogen production, and higher fibrinolytic activity.

We investigated the anti-obesity effects of Foeniculum fructus water extract on body weight, epididymal adipocyte size, plasma lipid levels and activities of key enzymes such as lipoprotein lipase (LPL), acyl-CoA synthetase (ACS) in high fat diet-induced obese mice. Experimental groups were normal diet group (ND), high fat diet group (HFD), high fat diet with 0.05% orlistat group (HFDO), and high fat diet with 0.5% Foeniculum fructus group (HFDF). Eleven-weeks feeding with HFD resulted in significant increase in lipid levels, body weight, liver and epididymal adipose tissue weight, compared with the ND group. Diet containing Foeniculum fructus water extract significantly reduced plasma total cholesterol, triglyceride and glucose concentrations as well as body weight, liver and epididymal adipose tissue weights. Plasma LDL cholesterol levels were significantly lower in the HFDF group than those in HFDO group. LPL activities elevated by a high fat diet were significantly decreased by Foeniculum fructus water extract administration. ACS activities decreased in the high fat diet group and markedly increased in the Foeniculum fructus water extract administered group. All things considered, Foeniculum fructus water extract efficiently inhibits the inflow of fatty acid into the cell, and activates metabolic process that uses fatty acids flowing as an energy source. Thus, Foeniculum fructus water extract may have great potential as a novel anti-obesity agent.

Backgroud: Pneumonectomy carries the possibility of numerous dangerous complications as well as the vast effect the operation itself has on the cardiopulmonary function. Most of operations are done with the insertion of the chest tubes upon completion, but because of the high incidence of pyothorax as its complications, we have tried to analyze and compare the cases without inserting the chest tubes. Material and Method: During a 5 year period from January, 1996 to December 2000, 100 cases, which were operated at the Hanyang University Hospital, were selected using the patient's charts. The age, gender, indication of operation, associated diseases, and operation site(left or right) were classified accordingly and the postoperative complications and mortality were statistically analyzed using the $\chi$ 2-test. After resecting the lung, the intrathoracic pressure was set at -15 ~ -20cm $H_2O$ using the nelaton catheter, and the thoracotomy site was then closed. The gradual collection of the fluid and blood in the thorax of the operated side, as well as the mediastinum location, were observed carefully for 4~5 days postoperatively with the aid of the simple chest x-rays. Result: Of the 100 cases, 16 cases of pulmonary tuberculosis(16%), 81 cases of lung tumor(81%), 2 cases of bronchiectasis(2%), and 1 case of aspergilloma associated bronchiectasis were noted. There were 8 mortality cases(8%), and of the 34 cases(34%), 44 complications were noted. The age, sex, and operation site(left or right) were not statistically significant with the complications. 7 of the 16 cases of pulmonary tuberculosis(44%) and 27 of the 81 cases of lung tumor(33%) had complications, but they were found not to be statistically significant. The increase of the complication rate in the pulmonary tuberculosis patients was 3.86. The evidence of postoperative bleeding was observed in 6 cases with the 3 cases being the pulmonary tuberculosis patients and the 3 cases were others. This shows that the increase in postoperative bleeding in the pulmonary tuberculosis is statistically significant(p=0.019). Of the 100 cases, there were 8 mortality cases(8%), with 5 cases from the 81 cases of the lung tumor group(6.1%), 3 cases from the 16 cases of pulmonary tuberculoses group(18.7%).

From July 1983 to December 1993, total 112 consecutive mitral valve replacements in 107 patients were performed in patient with mitral valvular abnormalities. To estimate the risk factor related to operative death, all patient's perioperative data were reviewed retrospectively. Except 20 patients received concomitant aortic valve replacement and 2 patients had incomplete data, 85 patients were included in this study. Mean age were $37.3\pm$ 13.1 years ranging from 13 to 72 years. Thirty-seven patients were male and fourty-eight patients were female. Mean follow-up durations were $51.1\pm33.8$ months ranging from 6 months t 11 years. Patients in this study showed improvement in mean NYHA functional clssification, from $3.02\pm0.73$ to 1 $78\pm0.55,$ and also in cardiothoracic ratio, from 0.61 $\pm0.09$ to $0.58\pm0.08$ at 6 months follow-up after operation. Operative complications were detected in 23 patients(27.1 %) and common postoperative complications were rhythm disturbance in 7 cases, pulmonary complications in 6 cases and low cardiac output syndrome in 6 cases. Early mortality was 10.6%(n=9) and the most common cause of death was a congestive heart failure due to low cardiac output syndrome. Main cause of our higher operative mortality than other study was that operative mortality in the initial period of our mitral surgery was high(5 operative deaths among 19 mitral valve replacement from July 1983 to December 1985). Actuarial survival was 80.8% at 5 years, 71.8% at 11 years including operative deaths. Actuarial freedom from anticoagulant-related bleeding was 85.3% at 5 years, 78.3% at 11 years. 95.1% at 5 years and 88.8% at 11 years among the patient in this study were free from thromboembolism, and 97.5% at 5 years and 75.1% at 11 years were free from reoperation. Preoperative cardiothoracic ratio and patient's age were statistically significant operative risk factors.

There has been great success for making transgenic animals using somatic cell nuclear transfer(SCNT) up to this time. However, the success rates of the production of live transgenic animals are still very low. The current research has been carried out for delineation of differentially expressed genes between SCNT and normal placenta in cattle. In the present observations, high expression has been observed for CTSZ, LOC509426 and ELF1 genes in normal placenta. On the other hand, TIMP2, PAG1B, PAG-21, LOC782894, SERPINB6 and mKIAA2025 protein were highly expressed in SCNT placenta. Five genes, which were highly expressed in SCNT placenta, have been further investigated using semi-quantitative real-time PCR. The results were similar to that we observed using ACP. In the future, all genes affecting the SCNT and normal placenta have to be discovered and their networks will be fully investigated. The genes were identified in this study would be great help for identifying differential gene expressions in SCNT placenta.

Purpose: The characteristics of hospitalized patients in neonatal intensive care units (NICUs), including hospitalization costs (HC) and National Health Insurance (NHI) status were studied. Methods: We gathered the following data from 7 hospitals in Korea during 2006: the distribution of patients according to birth weight (BW), and the duration of the hospital stay according to BW and He. Results: The patients who were admitted to the NICU consisted of high-risk neonates, including low birth weight or premature neonates, which comprised 50% of all neonates admitted to the NICU. The duration of hospitalization was 75-90 days for neonates with BW <1,000 g, 45-60 days for neonates with BW between 1,000 and 1,499 g, and approximately 15 days for neonates with BW between 2,000 and 2,499 g. The portion of the HC covered by the NHI was 77.1%, 22.9% of the total HC was not covered by the NHI (19.5% was included in the list, but not covered by the NHI and 3.4% was not listed, but covered by the NHI). The average total HC per person was 4,360,000 won, and the HC covered and not covered by the NHI were 3,677,000 won and 1,007,000 won, respectively. The mean HC were as follows; 35,000,000 won for a BW <500 g, 18,000,000 won for a BW between 500 and 999 g, 16,000,000 won for a BW between 1,000 and 1,499 g, and 4,200,000 won for a BW between 1,500 and 1,999 g. Conclusion: Not only premature, but also ill neonates were under the care of the NICU. The HC increased as the BW decreased and the hospitalization period increased. The proportion of the patient's financial burden is >25% of the total He. For this matter, additional NHI is needed.
