BACKGROUND: IL-8 is a potent chemotactic cytokine that plays an important role in the host defense mechanism against M. tuberculosis by recruiting inflammatory cells to the site of the infection. Lung epithelial cells, as well as alveolar macrophages are known to preduce IL-8 in response to M. tuberculosis. IL-8 gene expression is mainly regulated on the level of transcription by NF-κB. This study investigated whether or not A549 cells produce IL-8 in NF-κB dependent mechanism in response to macrophages phagocytosing M. tubersulosis. METHODS: Peripheral blood monocytes that were obtained from healthy donors were cultured for 24 h with M. tuberculosis and a conditioned medium(CoMTB) was obtained. As a negative control, the conditioned medium without M. tuberculosis (CoMCont) was used. A549 cells were stimulated with M. tuberculosis, CoMCont and CoMTB and the IL-8 concentration in the culture media was measured by ELISA. The CoMTB induced IL-8 mRNA expression in the A549 cells was evaluated using RT-PCR, and CoMTB induced IκBα degradation was measured using western blot analysis. CoMTB induced nuclear translocation and DNA binding of NF-κB was also examined using an electrophoretic mobility shift assay(EMSA), and the CoMTB induced NF-κB dependent IL-8 transcriptional activity was measured using a luciferase reporter gene assay. RESULTS: CoMTB induced IL-8 production by A549 cells(46.8±4.8 ng/ml) was higher than with direct stimulation with M. tuberculosis (6.8±2.9 ng/ml). CoMTB induced IL-8 mRNA expression increased after 2 h of stimulation and was sustained for 24 h. IκBα was degraded after 10 min of CoMTB stimulation and reappeared by 60 min. CoMTB stimulated the nuclear translocation and DNA binding of NF-κB. The CoMTB induced NF-κB dependent IL-8 transcriptional activity(13.6±4.3 times control) was higher than either CoMCont(2.0±0.6 times control) or M. tuberculosis (1.4±0.6 times control). CONCLUSION: A conditioned medium of peripheral blood monocytes phagocytosing M. tuberculosis stimulates NF-κB dependent IL-8 production by the lung epithelial cells.

Ureteral stricture is a problem that always has confronted urology. The development of balloon dilatation has introduced new modalities for the management of ureteral stricture disease. We experienced the ten patients of the ureteral stricture from July 1988 to April 1990. The following results were obtained. 1. Transluminal balloon dilatation is simple, safe technique for ureteral stricture. 2. After dilatation. most cases of stricture were improved on urography immediately. but follow up results were not so much improved. 3. Success rate of ureteral balloon dilatation was low (40% ). Therefore, we felt that secondary therapy modalities should be considered if first attempt was failed.

BACKGROUND: Phagocytosis is probably the first step for mycobacteria to be virulent in host because virulent strains are more readily phagocytosed by macrophage than attenuated strains. According 13 the traditional concept, multi-drug resistant strains have been regarded as less virulent. However, this concept has been challenged, since recent studies(reported) showed that the degree of virulence and drug-resistance is not related. The purpose of this study is to evaluate whether the phagocytic activity of M. tuberculosis by peripheral blood mononuclear cells(PBMC) is different according to drug-resistance or host factor. To evaluate this, we estimated the difference of phagocytic activity of drug-resistant and drug-sensitive M. tuberculosis and also estimated the phagocytic activity of PBMC from intractable tuberculosis patients and healthy controls. METHODS: PBMC from ten intractable tuberculosis patients and twelve healthy control and three different strains of heat-killed M. tuberculosis, ie, ADS(all drug sensitive), MDR(multi-drug resistant), and ADR(all drug resistant) were used. After incubation of various strains of M. tuberculosis with PBMC, the phagocytic activity was evaluated by estimating proportion of PBMC which have phagocytosed M. tuberculosis. RESULTS: Drug-resistant strains of M. tuberculosis were phagocylosed easily than drug sensitive strains(Percentage of PBMC phagocytosed M. tuberculosis in healthy control : ADS : 32.3α2.9%, ADR : 49.6α3.4%, p=0.0022, Percentage of PBMC phagocytosed M. tuberculosis in intractable tuberculosis patients : ADS : 34.9α3.6%, ADR : 50.7α4.5%), p=0.0069). However, there was no difference in phagocytic activity of PBMC from healthy control and intractable tuberculosis patients. CONCLUSION: Drug-resistant strains of M. tuberculosis were phagocytosed easily than drug sensitive strains and host factors does not seems to influence the phagocytosis of M. tuberculosis.

PURPOSE: The aim of our study was to identify the CT features helpful in the differential diagnosis of Iobar consolidation. MATERIALS AND METHODS: We evaluated the CT findings in 52 consecutive patients with Iobar consolidation which were proved to be pulmonary tuberculosis(n=24), malignant obstructive pneumonitis due to bronchogenic carcinoma(n=21), and lung abscess(n=7). We retrospectively reviewed CT scans with respect to 1) number of cavities or low attenuation area suggesting necrosis(we described these as cavity), 2) the contour of cavity, 3) enhancement of the cavity wall, 4) enhancement of pleura, 5) small nodules adjacent to the consolidation, 6) similar lesion in other location in lung, 7) air-bronchogram 8) mediastinal lymph node enlargement, and 9) extrapleural change. RESULTS: The helpful CT fingings in the patients with pulmonary tuberculosis were multiple cavities(more than three;79.2%), small nodules adjacent to the Iobar consolidation(75.0%), similar lesion in another lobe or lung(91.7%), air-bronchogram(91.7%), and mediastinal lymph node enlargement(58.3%). Although extrapleural change had low sensitivity it was highly specific for pulmonary tuberculosis(sensitivity, 43.5%;specificity, 91. 7%). Multiple cavities(61.9%) and mediastinal lymph node enlargement(52.4%) were common findings of malignant obstructive pneumonitis. In the patients with lung abscess, the common findings were small number of cavities(one or two, 85.7%) and air-bronchogram(85.7%). However, other findings of pulmonary tuberculosis were rarely seen in the patients with malignant obstructive pneumonitis or lung abscess. CONCLUSION: The CT findings of Iobar consolidation may be used as useful adjuncts in the differential diagnosis of Iobar consolidation.

Nucleolar organizer regions(NORs) are intranucleolar segments of DNA coding for ribosomal RNA and contribute to the regulation of cellular protein synthesis. Since NOR-associated proteins are argyrophilic, silver staining method has been used for demonstration of NORs. The numbers of argyrophilic NORs(AgNORs) have been shown to be correlated with DNA ploidy and have prognostic value in diverse human neoplasms. However, the prognostic value of AgNORs in renal cell carcinoma(RCC) remain ill defined. We herein investigated the prognostic value of AgNORs in 39 patients with RCC. There was no significant relationship between mean number of AgNORs (m AgNORs) per nucleus and Robson stage and Fuhrman nunlear grade. However, there was significant relationship between the percentage of tumor cells with more than five AgNORs per nucleus (p AgNORs) and Robson stage and nuclear grade (p<0.05). There was significant difference in survival rate between patients with RCC in whom AgNORs were two or less and in whom AgNORs were greater than two(p<0.05). The patients with a low p AgNORs(less than 8%) have a better prognosis than those with a high p AgNORs. These results suggest that number of AgNORs may be a clinically useful prognostic marker for patients with RCC.

Because most of modern peoples are busy with many their task according to specialization and complexity of society, it is impportant to determine optimal and comfortable time of colonoscopy. So this study was designed to compare efficacy of colonic cleansing and patient acceptance according to the time of colonoseopy. Among 140 peoples who underwent colonoscoyy in Busan St. Benedict Hospital between March 1995 to August 1995, two groups of 70 peoples were randomly assigned to undergo colonoscopy either at A.M. or ~P.M. The results were as follows: 1) In view of efficacy rate of colonic cleansing, the group at P.M, was superior to the group at A.M.. 2) In view of patients acceptance and side effects, the group at P.M. showed better acceptance and less side effects than the group at A.M.. In conclusion, this study showed that the colonoscopy at P.M. is better than at A.M., especially when patient is poor systemic condition or low acceptance to colonoscopic cleansing preparation. However, it may be also acceptable undergoing colonoscopy at A.M. if patient condition is good and patient is busy with his task.
