This study was conducted to evaluate extraction properties of crude saponin and ginsenosides, and their effects on sensory properties of emulsified pork sausage. Non-dried ginseng root was boiled in 0 (e.g., 100% distilled water), 20, 40, 60, 80 or 100% ethanol, and powdered by a freezing dry method. Weight of dried powder for the 0% ethanol extraction was 20% of initial non-dried ginseng weight, while $20{\sim}80%$ and 100% ethanol extractions resulted in approximately 15 and 10% of their initial weights, respectively. On the other hand, crude saponin content in the dried powder was linearly increased for a higher ethanol content where 100% ethanol extraction resulted in 123.52 mg/g. LC/MS analysis of crude saponin for quantifying ginsenosides showed that Rb1, Rb2 and Rc were significantly (p<0.05) higher levels for both 80 and 100% ethanol extractions. In the case of Rg1 ginsenoside, 60, 80 and 100% ethanol extractions resulted in significantly (p<0.05) higher levels. Emulsified pork sausages containing 0, 1 or 2% ginseng extracts were smoked or non-smoked and their sensory characteristics and preference were evaluated. Smoking process significantly (p<0.05) decreased juiciness and tenderness, but the treatment significantly (p<0.05) improved flavor and consumer preference. It was particularly noticed that a 2% addition of ginseng extract prevented the adverse effects of smoking process on juiciness and tenderness while the 2% addition significantly (p<0.05) improved consumer preference. The current results implied that addition of ginseng extract in emulsified pork sausage could improve sensory quality.

This study was conducted to evaluate the physicochemical properties of pork loin marinated with a solution of Nan and sodium tripolyphosphate, and the sensory attributes of tomato sauce-stewed products using marinated loin. Pork loin samples were cut $(3{\times}3{\times}2cm)$ and assigned to 3 treatment groups [C; unmarinated control (100% distilled water), T1; 10% sodium chloride, T2; 10% sodium chloride + 3% sodium tripolyphosphate]. Samples were marinated for 24hr at $5^{\circ}C$. The uptake of marinade in the treatment groups was significantly greater (p<0.05) than that of C, however no significant difference between the two treatments was observed. Cooking losses were highest (p<0.05) for T1, while lowest (p<0.05) for T2. All marinated loins had a significantly higher (p<0.05) yield than the control. The pH of the marinade solution ranged from 7.00 for T1 to 8.47 for T2. The two marinated loins had a significantly higher (p<0.05) $pH_{24}$ than the control. The water holding capacity (WHC) was highest for T2, and lowest for T1. CIE $L^*,\;a^*,\;b^*$ tended to be slightly higher in the control than either treatment group. The shear force value $(kg/cm^2)$ of yaw meat did not differ between the control and marinated muscle samples. However, cooked meat had a significantly lower (p<0.05) shear force value in T2 than C and T1. Hardness values were significantly lower (p<0.05) for both treatments compared with the control. There were no differences in texture profile, except hardness, between the control and the two treatments. Regarding the sensory evaluation of tomato sauce-stewed products manufactured with marinated pork loin, the treatment groups scored marginally well in tenderness, juiciness and overall acceptability, while the flavor score of the control was significantly higher than those of T1 and T2.
Background: Lymphangioleiomyomatosis(LAM) is a very rare disease occurring in women of reproductive age and leading to progressive respiratory failure despite therapy. But the natural history of this disease is uncertain and although anti-estrogenic agents have been used for more than twenty years, it's efficacy is still in debate. This study was performed to enhance understanding of this fatal disease in Korea by examining clinical, radiological, and pathologic findings of all the previously reported cases of LAM on Korea along with four new cases of LAM whom we report in this paper. Method: Out of twlve cases of LAM previously unpublished and published in domestic papers, two cases whose diagnoses were considered doubtful after review of clinical, radiological, and pathologic findings at "Asian Congress on Lymphangioleiomyomatosis" at Kyoto, Japan in feburary of 1993 were excluded from this study. Six cases which were reported previously and four new cases of LAM whom we report in this paper were analysed for the clinical, radiological, and pathologic characteristics. Results: All ten patients were women with mean age of $33{\pm}7$. The most common symptom was exertional dyspnea and most patients had history of pneumothoraces. Pulmonary function tests showed decreased diffusing capacity. on high resolution computed tomography(HRCT), all the cases had characteristic cysts. Most of the patients did not respond to hormonal therapy. Conclusion: In women of reproductive age, presenting with dyspnea who has a history of pneumothorax, LAM should always be considered as one of the diagnostic possibilities. If suspected, HRCT should be done to look for characteristic cysts and if needed, open lung biopsy should be done to confirm the diagnosis.
Background: Mediastinal masses are not uncommon, and an overall incidence of one case per 100,000 population per year in individuals of all ages and with no difference in sex incidence may be a reasonable estimation. At least half of all mediastinal masses are asymptomatic and this proportion has increased in recent decades with wider use of screening chest roentgenography. Symptoms in patients with mediastinal mass lesions are usually due to compression or invasion of nearby intrathoracic structures. Most mediastinal mass lesions have characteristic predilectional locations. The basic focus of diagnostic evaluation is an orderly preparation for obtaining a tissue diagnosis but even lesions discovered to be benign must generally be removed. Seldom is this status known for certain preoperatively. In additaion, benign tumors may continue to enlarge, thus compromising vital organs; they may rupture, hemorrhage, become infected or have the possibility of various malignant degeneration. Therefore, all mediastinal masses must be surgically removed whether they are malignant or benign. Methods: We reviewed the medical records of 344 cases previously confirmed as mediastinal tumors or cysts from January, 1960 to August, 1992 and investigated the clinical findings. Results: Neurogenic tumors were the most common(24.7%) and thymomas were distinctively increased recently. Overall ratio between males and females was 1.1:1 and age distribution was relatively even among all age groups. Predilectional sites were posterior for neurogenic tumors, and anterior for teratodermoid tumors, thymomas and lymphomas. Dyspnea was the most common symptom in the patients of the mediastinal tumors and asymptomatic patients were 19.5%, Benign mediastinal mass lesions were 66.0% and malignant, 34.0%, Complete or partial resection was done in 42.4%. Conclusion: We could find the increasing incidence and the tendency of aggressive resection as possible in the mediastinal tumors. We expect the discovery of more mediastinal tumors with wider use of regular check-up and development of diagnostic methods.
Background : This study was designed to examine how glutathione, one of the nucleophilic sulfur compounds, effects the cisplatin cellular toxicity in the non-small cell lung cancer cell lines and normal lung epithelial cell line. Materials and Methods : Three cultured cell lines, the lung adenocarcinoma cell(NCL-H23), the lung squamous carcinoma cell(SK-MES-1) and the normal lung epithelial cell(L-132) line were exposed to various concentrations of cisplatin with or without glutathione. The relative viability was estimated as a means of measuring the cisplatin cellular toxicity using the MTT method. Results : In NCI-23, the response to cisplatin was sensitive but glutathione markedly increased the relative survival of the tumor cells by removing the antitumor effect of cisplatin. In both SK-MES-1 and L-132, the responses to cisplatin were less sensitive, and the chemoprotective effect of glutathione compared to and equal cisplatin dose was significantly higher in L-132 than in SK-MES-1(p<0.05). Conclusion : The protective effectes of of glutathione on cisplatin-induced cellular toxicity is more significant in normal lung epithelial cells than in squamous carcinoma cells.

Background : Despite the clinical clues of bronchial asthma, some chronic coughers fail to be diagnosed due to negative test results. This study was aimed at evaluating the diagnostic performance of routine objective tests and identifying a cost-effective approach for asthmatics with a chronic cough. Methods : Patients with a chronic cough of more than 3 weeks duration, and showing normal chest radiograph and spirometry were enrolled. On the first visit, objective tests, composed of serum total IgE, peripheral blood eosinophil count, spontaneous sputum eosinophil count, methacholine bronchial provocation test (MBPT) and paranasal sinus radiograph, were performed, with the simultaneous administration of oral prednisolone (0.5mg/kg) for one week. The final diagnoses were made on the basis of the test results, and the patients grouped according to their steroid responsiveness. The role of the etiologic diagnosis tests was evaluated, and the medical costs of the final management plan simulated with respect to three assumed models. Results : Sixty chronic coughers were finally analyzed. The final diagnoses were as follows: bronchial asthma 21.7%, eosinophilic bronchitis 6.7%, paranasal sinusitis 18.3%, presumptive allergy 8.3% and non-diagnostic case 45.0%. Ninety percent were steroid responder. With the bronchial asthma cases, the positive rate of MBPT was 38.5%, with sputum eosinophil count in 84.6%, serum total IgE in 38.5%, and a peripheral blood eosinophil count rate of 30.8%. When the test results and steroid responsiveness data were applied to the 3 models, the chest radiograph, spirometry, sputum eosinophil count and paranasal sinus radiograph test results, and simultaneous short term steroid treatment seemed to have acceptable diagnostic performances, which could be used as a further guide to cost-effective planning. Conclusion : Objective tests, composed of chest radiograph, spirometry, paranasal sinus radiograph and sputum eosinophil count, with simultaneous short term steroid treatment, are suggested as cost-effective approaches for asthmatics with a chronic cough.

Background: Tsutsugamushi, leptospirosis and hemorrhagic fever with renal syndrome (HFRS) are the prevalent diseases among the acute febrile illnesses in Korea. Pulmonary involvement in the patients with these diseases remains poorly recognized in endemic regions, and this is despite reports of recent outbreaks and epidemic episodes. Pulmonary involvement and a higher CRP level as clinical manifestations show a more severe form of infection. The aim of this study is to analyze the correlation of pulmonary involvement and the CRP level in patients with acute febrile illnesses. Methods: We retrospectively reviewed the clinical records of 105 patients who were diagnosed with tsutsugamushi, HFRS and leptospirosis from January 2002 to May 2008 in Chuncheon Sacred Heart Hospital. The radiographic images were retrospectively analyzed by two radiologists. We analyzed the pulmonary complications of the patients with these febrile diseases and we checked the CRP level at admission. Results: The study included 105 patients who were diagnosed with febrile diseases. Of these patients, 32 patients had hantaan, 10 patients had leptospirosis and 63 patients had tsutsugamushi disease. 42 (40%) patients had pulmonary complications, 20 patients had pulmonary edema, 20 patients had pleural effusion and 2 patients had interstitial pneumonitis. The patients with pulmonary involvement showed a more severe form of infection and a higher CRP level than that of those patients without pulmonary involvement (p=0.0073). Conclusion: Pulmonary involvement in patients with acute febrile diseases might be correlated with a higher CRP level. Identification of this factor on admission might provide useful selection criteria for the patients who need early intensive care.
Background: There are various etiologies causing bronchiectasis, but the cases without definite causes account for a quite high proportion. It is also uncertain that immunoglobulin G subclass deficiency (IgGSD) is associated with bronchiectasis. Therefore, we tried to measure the frequency of IgGSD in patients with bronchiectasis of unclear etiology, and to observe the clinical features of those patients with bronchiectasis and IgGSD. Methods: For the outpatients of a university hospital who were diagnosed as bronchiectasis by chest CT, we produced comprehensive history taking and physical examinations, and finally selected 31 patients with bronchiectasis of unclear etiology. Results: Two patients had total immunoglobulin G deficiency. The frequency of IgGSD was comparatively high (n=14). When we compared IgGSD group to normal immunoglobulin G subclass group, there were no significant differences in sex, age, and the frequency of sinusitis, bronchial asthma, and the abnormal lung function. Conclusion: In cases of bronchiectasis without definite causes, it can be considered to measure the level of immunoglobulin G subclass. It is also probably worthwhile to further evaluate the relationship between IgGSD and bronchiectasis.
Background: Nosocomial pneumonia in an intensive care unit (ICU) is associated with a high mortality rate. Diagnosing a respiratory tract infection in critically ill patients is still difficult but detailed information for the pathogens is needed to establish an adequate antimicrobial treatment. This study examined the causative organisms and their antimicrobial resistance using bronchoalveolar lavage (BAL) from patients suspected of having pneumonia in the ICU. Methods: From January 2004 to June 2006, ICU patients with diffuse lung infiltration were prospectively enrolled. The BAL was used to diagnose the respiratory infection, with 104 > or = organisms considered a positive result. The most common organisms and their antimicrobial resistances were analyzed from the quantitative BAL cultures in the burn ICU and non-burn ICU. Results: A total 72 patients were included, 35 (M 29, F 6) in the burn ICU and 37 (M 26, F 11) in the non-burn ICU. 27 patients (77.1%) in the burn ICU and 22 patients (59.5%) in the non-burn ICU met the criteria for a positive BAL culture. The major pathogens were Staphylococcus aureus, Acinetobacter species and Pseudomonas aeruginosa. All strains (100%) of Staphylococcus aureus isolated from BAL (9 cases) were methicillin-resistant (MRSA) in the burn ICU, but 5 strains (71.4%, 7 cases) were MRSA in the non-burn ICU. Regarding Pseudomonas aeruginosa, the rate of resistance to amikacin, ciprofloxacin, cefepime, imipenem, ceftazidime, piperacillin/tazobactam in the burn and non-burn ICU ranged from 45.5% to 90% and 25% to 50%, respectively. In addition, the rate of resistance of Acinetobacter species to the above drugs in the burn and non-burn ICU ranged from 81.8% to 100% and 62.5% to 100%, respectively. Conclusions: These results are expected to provide useful guidelines for choosing the effective empirical antimicrobial therapy in patients with lung infiltrations in the burn and non-burn ICU.

Background: The efficacy of the use of the interventional bronchoscope for palliation of patients with central airway obstruction has been established. In the palliative setting to alleviate central airway obstruction, the use of laser resection, electrocautery, argon plasma coagulation, photodynamic therapy and cryotherapy can provide relief of an airway obstruction. Cryotherapy is the therapeutic application of extreme cold for the local destruction of living tissue. Recently, this technique has been used for endoscopic management of central airway obstructions in Korea. We report the role and complications of the use of cryotherapy for airway obstructions in patients with advanced lung cancer. Methods: We used a flexible cryoprobe for cryotherapy using nitrous oxide as a cryogen. The cryoprobe was applied through the working channel of a flexible fiberoptic bronchoscope. The temperature of the tip was approximately $-89^{\circ}C$, and the icing time was 5~20 seconds. Results: Four patients with a central airway obstruction from advanced lung cancer were treated with cryotherapy. Three of the four patients were treated successfully and the airway obstruction was improved after the cryotherapy procedure. Dyspnea, hypoxia and atelectais were improved in three cases. Two patients experienced complications- one patient experienced pneumomediastinum and the other patient experienced massive hemoptysis during the cryotherapy procedure. However, these complications resolved and did not influence mortality. Conclusion: This technique is effective and relatively safe for palliation of inoperable advanced lung cancer with a central airway obstruction.
