Background : Cervical tuberculous lymphadenitis(CTL) is one of the most common extra-pulmonary tuberculosis. Recently overall incidence of pulmonary tuberculosis has decreased, but the incidence of tuberculous lymphadenitis has not decreased. Its duration of treatment is still controversial and the pathogenesis, prognosis and relationship with other site tuberculous are poorly published. So we did a retrograde study of 120 cases of confirmed CTL about its clinical manifestations. Method : All patients were applied fine needle aspiration(FNA) of palpable enlarged cervical lymph nodes and 114 patients were examined for AFB smear and 34 patients for TB culture with aspirated fluid. 57 patients were examined Mantoux test(5TU with PPD-S). With above methods, a total of 120 patients was diagnosed as having CTL. Results : 1) CTL is most prevalent in young women between the age of 20~30 years and the incidence of CTL in female is 2.5 times higher than that of male. It is located most commonly in the posterior cervical area. The most common presenting symptom is painless palpable enlarged cervical lymph nodes. 2) With FNA of enlarged cervical lymph nodes, the percentage of histopathological positivity is 82.3%. The percentage of AFB smear positivity is 38.6%, and that of TB culture positivity is 17.6%(p<0.001). 3) Pulmonary tuberculosis is noted in 79 cases(65.8%). And 42 cases(53.5%) of them had minimal pulmonary tuberculosis. In 14 cases(11.7%), other extrapulmonary tuberculosis coexsisted and pleural tuberculosis was most Common in the order. 4) CTL was treated with anti-tuberculous medication(first line drug) and median treatment duration was 18.5months. During treatment, the size of involved lymph nodes decreased gradually in 62 cases(75.8%), newly developed lymph nodes were found in 25 cases(30.4%), fluctuation formation in 22 cases(26.8%) and fistula formation in 14 cases(17.0%). Conclusion : CTL is prevalent in women between the age of 20~40 years and it involves posterior cervical area most commonly. CTL is treated with long-term anti-tuberculous chemotherapy. We think it is one manifestation of systemic disease and frequently coexisting with pulmonary tuberculosis. Despite anti-tuberculous chemotherapy, the size of involved lymph nodes was increased, new lymph nodes were developed or fluctuation and fistula formed in involved lymph nodes. After sufficient medication, when the patient felt pressure discomfort from enlarged lymph node or fistula was formed, we recommended total excision of involved lymph nodes.

Various methods for the isolation of salmonellae were compared by examining mesenteric lymph nodes and faeces of 395 pigs at slaughter. The conclusions were as follows. (i) Tetrathionate broth was significantly superior to selenite broth for the examination of mesenteric lymph nodes. (ii) There was no significant difference between tetrathionate broth and selenite broth for the examination of faeces. The use of both tetrathionate broth and selenite broth as enrichment media for faeces produced far better results than the use of any single enrichment medium. (iii) Brilliant green agar was significantly superior to SS agar for the examination of mesenteric lymph nodes. (iv) There was no significant difference between brilliant green agar and SS agar when faeces were examined. The use of both media produced far better results than the use of either singly. (v) Brilliant green MacConkey broth was much inferior to tetrathionate broth as an enrichment broth. Direct culture of faeces on brilliant green MacConkey agar yielded less isolates than prior enrichment in tetrathionate or selenite broth. (vi) The optimum incubation period of enrichment was 24 hours for faeces and 48 hours for mesenteric lymph nodes when either tetrathionate broth or selenite broth was used as enrichment media.

Local excision and axillary dissection followed by radiation therapy to the breast has been shown to achieve equivalent local control and survival as mastectomy in an prospective randomized trials. We analyzed 28 cases of early breast cancer in order to evaluate the therapeutic effects of conservative surgery and definitive radiotherapy in the management of early breast cancer as possible alternative of simple mastectomy, retrospectively. Obtained results were as follows : 1. Treatment related acute side reactions are more prominant in the case of chemoradiotherapy group than radiotherapy alone group. 2. There were no cases of primary, regional or systemic failures on the last follow up examination. 3. Cosmetic results after treatment were satisfactory in 26 cases out of 28 cases on the last follow up examination. 4. There were no demonstrable differences of tumor control and cosmetic results between the treatment groups. Although, these results suggested that definitive radiotherapy after local excision would be a possible and desirable alternative instead of total mastectomy in the management of early breast cancers, analyzed cases were too small and follow up period was too short to evaluate the therapeutic effect of primary radiotherapy after local excision, exactly.

Bovine tuberculosis is generally detected postmortem because it is a chronic debilitating disease. Since tuberculosis is mainly found in the lungs, clinical signs including coughing, nasal discharge, and difficulty breathing can occur in severe instances. In the present study, specimens were collected from the heart, liver, kidney, lung, pleural cavities, lymph nodes and intestines of carcasses found in an abattoir. According to post-mortem examination and inspection of carcasses, tuberculosis lesions were varied in appearance and size. Tubercles of a white cream color were disseminated throughout the pleural cavity including the lymph nodes, lungs and mesentery containing pus. Gram and Ziehl-Neelsen's acid-fast staining for the lung and lymph nodes revealed a highly positive histochemical reaction. The acid-fast organisms were observed histologically in the lesions under a microscope. This report demonstrated the histopathology of bovine tuberculosis based on the histological findings of Mycobacterium bovis, which is a suspected causative agent.

The interpretation of observed waveform characteristics identified in refraction and wide-angle reflection data increases confidence in the crustal structure model obtained. When calculating traveltimes and raypaths, wavefront methods on a regular grid based on graph theory are robust even with complicated structures, but basically compute only first arrivals. In this paper, we develop new algorithms to compute traveltimes and raypaths not only for first arrivals, but also for fast and later reflection arrivals, later refraction arrivals, and converted waves between P and S, using the modified wavefront method based on slowness network nodes mapped on a multi-layer model. Using the new algorithm, we can interpret reflected arrivals, Pg-later arrivals, strong arrivals appearing behind Pn, triplicated Moho reflected arrivals (PmP) to obtain the shape of the Moho, and phases involving conversion between P and S. Using two models of an ocean-continent transition zone and an oceanic ridge or seamount, we show the usefulness of this algorithm, which is confirmed by synthetic seismograms using the 2D Finite Difference Method (2D-FDM). Characteristics of arrivals and raypaths of the two models differ from each other in that using only first-arrival traveltime data for crustal structure analysis involves risk of erroneous interpretation in the ocean-continent transition zone, or the region around a ridge or seamount.
