28세 남자가 내시경적 점막절제술을 통해 저등급 위MALT 림프종으로 진단되었다. 병기설정을 위해 18F-FDG PET 검사를 시행하였고 우측 쇄골상부, 우측상/하부 기관주위, AP window 부위에 강한 섭취가 관찰되어 전이성 림프절로 판단하였다. 그러나, 우측 쇄골상부 림프절에서 시행한 절제생검에서 만성육아종성염증소견이 관찰되었고 조직의 결핵 중합효소연쇄반응에서도 양성 반응을 보였다. 2개월간 항결핵제의 사용 후 시행한 추적 컴퓨터단층촬영 검사에서 림프절 크기의 감소를 보여 최종적으로 위 MALT 림프종에서 광범위 림프절 전이로 오인된 동시성 림프절 결핵으로 진단되었다. A 28-year-old man was diagnosed as gastric MALT lymphoma in diagnostic EMR (endoscopic mucosal resection). He subsequently underwent an 18F-FDG PET. 18F-FDG PET showed intense multifocal uptake in right supraclavicular, right upper and lower paratracheal, and AP window areas that was considered radiologically to represent widespread metastatic lymphadenopathy. Excisional biopsy of a supraclavicular lymph node, however, revealed chronic granulomatous lymphadenitis with a positive reaction of Tb-nested PCR. After antituberculosis treatment for 2 months, a follow-up CT scan showed complete resolution of the lesions. Intense 18F-FDG uptake could be due to an infectious process such as synchronous tuberculous lymphadenitis. Therefore, this could mimic a malignant condition such as lymphoma with extensive lymph node metastasis due to a false-positive finding, which may lead to a misdiagnosis.

점액낭종은 소타액선 분비관의 폐쇄나 파열로 타액이 저류되어 발생하는 연조직 부종이고, 비교적 높은 빈도로 발생하는 구강내 가성 낭종으로 스스로 파열되어 치유되기도 하지만 대개는 만성적으로 진행되어 몇 주에서 몇 달간 지속되기 때문에 치료가 필요하다. 점액 낭종의 발생시, 주변에 이환된 소타액선을 포함하여 제거하는 완전절제술 외에 재발율을 낮추기 위한 스테로이드의 국소적 주입, 냉동동결요법(cryotherapy), 미세조대술(micromarsupialization) 등의 여러 가지 치료방법이 제시되고 있다. 완전절제술의 한 방법으로 생검펀치(biopsy punch)를 이용할 수 있는데, 조작이 간편하고 출혈이 적으며 술 후 처치가 거의 필요없다는 장점이 있다. 이 증례는 점액낭종이 있고 행동 조절이 힘든 소아에서 생검펀치를 사용하여 점액낭종을 완전히 제거한 경우로, 양호한 결과를 얻었다. Mucocele is a clinical term of the localized superficial mucosal swelling caused by salivary retention after the obstruction or the rupture of minor salivary ducts. Various treatment methods have been suggested to lower its recurrence rate, including complete excision of lesion Biopsy punch can be used easily and simply for complete excision of mucocele. It has several advantages, such as convenience in use, low bleeding tendency, and nearly no requirements for post-operative management. In this case, biopsy punch was used for the removal of mucocele in an uncooperative child, which enable fast, simple and safe procedure, with a good result.

Campbell Early(Vitis labruscana B.) grape shoot tips derived from cuttings were cultured on modified basal media of Murashige and Skoog(MS) differing in pH, nitrogen strength, N-source(NO3 - N and NH4- N), Cl- and SO42-, and their responses to nutrient uptake were investigated. 1.Optimal pH for mineral absorption except P was 5.0. 2.Maximum nutrient uptake was obtained with 0.50 - (0.50N) to 0.75-fold nitrogen (0.75 N) media. 3.Increase in total mineral contents of P, K, Ca, and Mg in shoot mass derived from one initial shoot tip was proportional to NO3-N level while N absorption was enhanced with 75 : 25 to 50 : 50(NO3-N : NH4-N) media. 4.MS medium with both Cl- and SO42- was favorable for N uptake. Absorption of P, K, and Mg was greater with the media composed only with SO42-, while Ca uptake was stimulated with Cl- media.
햄스터 구강암 발생 과정에서 Heat Shock Protein에 관한 면역조직화학적 연구

A IMMUNOHISTOCHEMICAL STUDY ON HEAT SHOCK PROTEIN IN ORAL CARCINOGENESIS IN HAMSTER Heat shock protein (HSP) expression is unto·emulated in tumor cells and, HSP expression is likely marker of the malignant potential of oral epithelial lesion. Furthermore, the 70kDa HSP is implicated in the degree of tumor differentiation, the rate of tumor proliferation and the magnitude of the anti-tumor Immune response. Accordingly, the distribution and intensity of HSP70 and HSP47 expression was assessed in the DMBA induced oral carcinogenesis in hamster. Golden Syrian hamsters which were 3 months-age and 90∼120g were collected. 9,10-dimethyl -1,2-ben-zanthracene (DMBA) in a 0.5% solution in mineral oil was painted on the buccal pouch mucosa 3 times per week in the study group. In each control and experimental groups of 6, 8, 10, 12, 14, 16, 18, 20 weeks, specined for immunohistochemical study with anti-HSP47 and anti-HSP70 antibody. The following results were obtained. 1.HSP47 positive cells were race or negative of normal oral mucosa, increased mildly in basal and suprabasal basal layer, and spinous cell layer after experimental 6 weeks (dysplastic or CIS stage). In CIS stage, HSP47 expression is prominent in dysplastic free or normal adjacent epithelium. 2.HSP47 positive cells in connective tissue were mainly inflammatory cells, which is gradually increased from control to precancerous and cancer stage. But HSP47 positive cells after 14 weeks were decreased, especially normal and cancer adjacent epithelium. 3.The positive staining cells of HSP70 in control, dysplastic, and CIS stage were not seen. But they were mild findings in basal layer and moderate findings in spinous layer after experimental 14 weeks (cancer stage). 4.HSP70 positive cells were increased in precancerous and cancer stage than control group in connective tissue. After experimental 16 weeks, we could not find the HSP expression in cancer cells according to cancer differentiation or cancer stage. It is concluded that HSP70 or HSP47 expression is not a definitive marker of oral malignancy or malignant potential. However, with further development, HSP immunoreactivity may be valuable as an adjunct to conventional histology for assessing the malignant potential of oral mucosal lesions.
HL-60 세포주를 이용한 결핵균항원의 세포성면역반응의 분석

Most persons who become infected with M. tuberculosis mount a protective immune response and remain clinically well, the only evidence of infection being development of a positive tuberculin skin test. Five to 10% develop tuberculosis disease within the first 2 years after infection (primary tuberculosis) or thereafter (reactivation tuberculosis). Acquired resistance against tuberculosis paradigmatically rests on cell-mediated immunity, with the major factors being mononuclear phagocytes and T Lymphocytes. While the former cells act as the principal effectors, the latter ones serve as the predominant inducers of protection. The usefulness of the single dose of BCG routinely given in childhood in many developing countries in preventing far more commonly occurring tuberculosis in adults is in doubt. An effective and safe vaccine against tuberculosis is sorely needed. A subunit vaccine are capable of inducing protective immunity and could have substantial advantages over BCG or other whole-bacterium vaccines. The human promyelocytic cell line HL-60 adopted characteristic macrophage-like properties, including adherence and CD14 expression after a period of continuous culture at high ambient CO_(2) concentration. When HL-60 cells were cultured with 1,25-dihydroxyvitamin D_(3) for 4 days, the cells acquired the activity to potentiate T cell proliferation by the 30 kDa or 38 kDa antigen of Mycobacterium tuberculosis H37Rv Therefore, vitamin D-treated HL-60 cells showed the function of the antigen presenting cells.
