Sparganosis is a parasite infestation caused by the larval stage of Spirometra erinacei. Ingestion of raw or undercooked flesh of numerous intermediate hosts results in human infection. Sparganum infestation of human body was reported over 120 cases including urogenital lesions in Korean literatures since 1924. But, no case of sparganosis in the spermatic cord was reported until now. We experienced a case of sparganosis in the spermatic cord.

BACKGROUND: Small-cell carcinoma of lung has a tendency of rapid growth and early wide metastasis. In spite of high response rate of combination chemotherapy alone or with radiotherapy, overall long-term survival rate is very disappointed. According to autopsy findings, the common cause of failure is local recurrence in primary cancer site. So, surgical resection with combined chemotherapy has been recently attempted for very early stage of small-cell carcinoma of lung. METHODS: 10 patients (TNM I: & II: 5 cases) undergoing surgical resection for small-cell carcinoma of lung with adjuvant chemotherapy in an attempt to prolong survival. Of these, 9 patients received chemotherapy, and retrospective study was undertaken for survival (Kaplan-Meier analysis). RESULTS: Median survival time was 26 months, 2-, 5-year survival rate was 68.6%, 46.7%. If 1 patient without chemotherapy was excluded, 2-, 5-year survival rate was 76.2%, 50.8%. No survival difference was seen between patients with TNM I, II stages. CONCLUSION: Adjuvant chemotherapy after surgical resection results in prolonged survival for patients with TNM stage I, II small-cell carcinoma of lung.

PURPOSE: The purposes of this study were to investigate the effect of Korean Red Ginseng(KRG) extract on the relaxation of the clitoral corpus cavernosal smooth muscle in rabbit. MATERIALS AND METHODS: Rabbit clitoral corpus cavernosal smooth muscle strips were mounted in organ chambers to measure isometric tension. The strips were contracted with phenylephrine(5 x 10(-6) M), and the responses to KRG extract(1~20 mg/ml), nitric oxide inhibitor(N omega-nitro-L-arginine methyl ester, L-NAME), vasoactive intestinal peptide(VIP) receptor antagonist, KCl were examined. The cGMP content of the strips was measured by radioimmunoassay after various dose of KRG extract. RESULTS: The KRG extract(1~20 mg/ml) relaxed the clitoral corpus cavernosal smooth muscle in a dose-dependent manner up to 95%. The relaxation effect of KRG extract was significantly inhibited by L-NAME(10(-4) M) in clitoral corpus cavernosal smooth muscle. The KRG extract also inhibited the contraction induced by depolarization with 10, 20, 40 mM of KCl. The KRG extract(1, 5 mg/ml) increased the accumulation of cGMP in clitoral corpus cavernosal smooth muscle. CONCLUSIONS: These data suggest that KRG extract has a relaxing effect on the clitoral corpus cavernosal smooth muscle in rabbit. These effects are in part mediated by the NO-cGMP pathway and a hyperpolarizing action.

BACKGROUND: The possibility of developing pulmonary tuberculosis usually increases with increasing age. Therefore, the incidence of endobronchial tuberculosis in older people may increase. We evaluated the clinical characteristics in patients with endobronchial tuberculosis above the age of 70 years. METHODS: We enrolled 74 patients (12 males and 62 females; mean age 64.6+/-16.2 years) that were diagnosed with endobronchial tuberculosis from March 2003 to July 2006 at Gyeongsang University Hospital. We retrospectively evaluated the clinical characteristics of endobronchial tuberculosis for patients 70 years or older (older group) and for patients below the age of 70 years (younger group). RESULTS: The number of patients in the older group was 41 (55%). Cough was the most common symptom in the two groups of patients and dyspnea on exertion was more common in the older group of patients than in the younger group of patients (31.7% vs. 12.1%). The actively caesating type of disease was more common in the younger group of patients than in the older group of patients (66.7% vs. 39%). The edematous type of disease was more common in the older group of patients than in the younger group of patients (53.7% vs. 27.2%) (p<0.05). Tracheal and main bronchial involvement of lesions were more common for the younger group of patients than for the older group of patients (30.3% vs. 9.7%) (p<0.05). CONCLUSION: Endobronchial tuberculosis was commonly observed in patients older than 70 years and this group of patients had some clinical characteristics that were different from the younger group of patients.

BACKGROUND: Airway inflammation and hyperresponsiveness are recognized as major characteristics of bronchial asthma. Airway inflammation has usually been assessed by invasive methods, e.g. BAL or bronchial biopsy, but recent studies proposed induced sputum as another reliable and non- invasive tool to investigate airway inflammation in asthmatic patients. Thus, the relationship between airway inflammation assessed by induced sputum and airway hyperresponsiveness was investigated in asthmatic patient. METHOD: Airway responsiveness was determined by the concentration that caused a 20% decrease in FEV1(PC20) after inhaling incremental concentrations of methacholine. The numbers of inflammatory cells and the concentration of eosinophilic cationic protein(ECP) were assessed in induced sputum obtained by inhalation of hypertonic saline(3%). RESULT: We analyzed sputum induced in 15 stable asthmatic patients. 1. The differential cell count(%) of macrophages, neutrophils, eosinophils and lymphocytes in induced sputum were 39.1 +/- 27.0%, 29.6 +/- 21.0%, 28.8 +/- 18.8%, 1.3 +/- 3.1% respectively. 2. The mean value of baseline FEV1 (Predicted) and ECP were 76.3 +/- 30.3% and 1,101 +/- 833 micro gram/L respectively. The geometric mean value of PC20 was 0.56mg/mL. 3. The relationships between the sputum eosinophil and ECP in induced sputum, and between sputum eosinophil and degree of airway responsiveness(PC20) were found be significantly correlated (r=0.81, p<0.05 and r=-0.78, p<0.05, respectively). 4. Sputum neutrophils and PC20 were not correlated to each other (r=0.11, p=0.69) and a significant negative correlation was found between ECP and baseline FEV1(predicted) (r=-0.62, p<0.05). CONCLUSION: The results of this study suggest that an induced sputum via a inhalation of hypertonic saline is useful to determine a patient's status of airway inflammation, and airway inflammation is one of the major causal factors in the development of bronchial hyperresponsiveness in asthmatic patients.

BACKGROUND: Vitamin C has been reported to have a role in the decrease of airway hyperresponsiveness in animal models. This data is based on some metabolic actions of vitamin C, such as promotion of histamine degradation, producing mote PGE2 than PGE2 alpha in cyclooxygenase pathway, decrease of smooth muscle contraction, and acting as reducing agent of oxidant. It has been also known that heavy smokers have lower blood levels of vitamin C than nonsmokers and this deficiency in heavy smokers have been explained by several mechanisms, such as increased oxidation by oxidants and free radicals, increased biosynthesis of catecholamine and serotorim released by nicotine, and inadequate dietary intake. In this study, We attempted to assess effect of vitamin C on bronchial hyperresponsiveness in heavy smokers who have bronchial hyerresponsiveness and role of vitamin C on bronchial hyperresponsiveness. METHOD: To assess acute effect of vitamin C on airway hyperresponsiveness, blood sample for vitamin C level and spirometry, methacholine challenge test were done in 17 smokers and 8 nonsmokers, and one hour after oral administration of vitamin C 3 g, blood sample for vitamin C level and spirometry, metliacholine challenge test were repeated. To assess chronic effect of vitamin C on airway hyperreeponsiveness after daily administration of vitamin C 1 g for one week in 17 smokers, blood sample for vitamin C level and spirometry, methacholirie challenge test were done. To assess role of vitamin C, after oral administration of vitamin C 3 g plus indomethacin 100 mg in 12 of 15 smokers who were reactive to methacholine challenge test, spirometry and methacholine challenge test were done and after oral intake of indomethacin 100 mg in 12 smokers who were reactive to methacholine challenge test, spirometry and metbachoine challenge test were repeated. RESULT: There were no significant differences in whole blood vitamin C levels between smokers(1.17+/-0.22mg/dL) and nonsinokers(1.14+/-0.19 mg/dL) (p>0.05). Fifteen of the 17 smokers(88.2%) were reactive to metbacholine chaflenge test amd 10 of the 15 smokers who were reactive to methacholine challenge test were less than 8 mg/dL in PC20FEV1, and 7 of the 8 nonsmokers(87.5%) were nonreactive to methacltoline challenge test There were significant decrease in bronchial responsiveness after oral administration of xitamin C 3 g in 13 of the 15 smokers who were reactive to methachoine challenge test. This significant decrease persisted with maintenance daily administration of 1 g for one week. PC20FEV1 were not correlated to vitamin C levels in smokers. After oral administration of indomethacin 100 mg, significant reduction of bronchial responsiveness that occured after oral administration of xdtamin C 3 g in smokers were attenuated. CONCLUISON: Although there were no significant differences in whole blood vitamin C levels between smokers and nonsmokers, heavy smokers have significant increase in bronchial responsiveness than nonsmokers. This bronchial hyperresponsiveness of heavy smokers can be attenuated by vitamin C supplement Disappearance of vitamin C effect by indcrnethaein supplement may suggest that vitamin C exert its effect via alteration of arachidonic acid metabolism.

OBJECTIVE: We assessed the prognostic factors and the efficacy of adjuvant therapy and reviewed randomized studies carried out on patients receiving adjuvant therapy with early endometrial carcinoma. METHODS: One hundred and five patients that received primary surgical treatment for stage IB, IC and II endometrial cancer were enrolled in this study. The clinical outcomes were compared among the patients with variable prognostic factors and adjuvant treatments. RESULTS: One hundred and five patients fulfilled the eligibility criteria and 46 patients (43.8%) underwent adjuvant therapy. Disease recurrence occurred in nine patients within a median time of 24 months. Cervical involvement was an independent prognostic factor for the disease-free survival rates. Eight of 16 patients with FIGO stage II disease received adjuvant chemotherapy consisting of cisplatin and etoposide (or cyclophosphamide) or combined chemoradiation. The 5-year disease-free survival rate for these patients was 87.5%, a value significantly higher than for patients that received radiation therapy alone (30%). CONCLUSION: Adjuvant chemotherapy or combination chemo-radiotherapy might be superior to radiation therapy alone in high-risk early endometrial cancer patients.

Approximately half of the patients with systemic lupus erythematosus(SLE) develop localized or diffuse lymphadenopathy during the evolution of the disease. But hilar and mediastinal lymph node enlargement due to SLE is rare. The histologic findings of lupus lymphadenitis range from nonspecific lymphadenitis with variable degrees of cellular necrosis to the less common but more specific appearance of extensive necrosis. Advanced lesions are characterized by hematoxylin bodies and condensation of DNA on the vessel walls. Hematoxylin bodies are amorphous homogeneous violet or lilac colored structures composed of partially depolymerized DNA, mixed with protein, carbohydrates and globulins which may be seen deposited on vessel walls and within the paracortex of lymph node. They are virtually diagnostic of SLE and would exclude malignant lymphoma. SLE with mediastinal lymphadenopathy is rare so we report this case with a review of literatures, which was diagnosed by hematoxylin bodies on pathologin findings of cervical lymph node.
