Malignant fibrous histiocytoma rarely occurs in the jaws. Although the histogenesis of this tumor remains controversal, it is best regarded as a primitive and pleomorphic nature reflected by collagen production and occasional phagocytosis. It is common for metastatic foci to appear in lung and regional lymph node. There are variable treatments such as radiotherapy, surgical excision or combination, therapy of surgical excision, chemotherapy and radiotherapy. With the review of literatures, the authors report the clinical study of two cases of malignant fibrous histiocytoma of the jaw.

In order to study the toxic effect of adriamycin on the formation of dentin of the rat, adriamycin(5㎎/㎏ body weight) was injected intravenously, and animals were sacrificed at 1, 3, and 10 days after administration. In the light micrographic observation, aggregation of densely stained cells were observed along the wall of the pulp canal and the odontoblastic layer disappeared after 1 and 3 days. The predentin was not even thickness and irregular in boundary compared to normal predentin. The formation of osteodentin, which has cellular inclusions in the matrix, was noted after 10 days. Electron microscopic observation revealed that the cells in aggregation had long slender cytoplasmic processes and contained more profiles of endoplasmic reticulum and secretory granules. The odontoblasts showed degenerative changes such as cytoplasmic vacuolation and fragmentation of rEr. The cells in the osteodentin and on the surface of irregular osteodentin contained dilated cisternae of rEr and secretory granules. Some cells showed necrotic and degenerative changes. There were no odontoblastic processes and dentinal tubules in the osteodentin matrix, central region of which was densely packed with collagen fibers. It therefore appears that osteodentin formation was observed in the pulp of root canal after adriamycin administration and it is the result of an abnormal differentiation of pulp mesenchymal cells.

목적 : 본 연구는 지방조직과 혈청의 PCBs와 DDE 농도를 측정하고, 이에 영향을 미치는 것으로 알려진 요인들과의 관련성을 평가하고자 하였다. 방법 : 유방암, 자궁내막증 등 유기염소계 화합물의 영향이 있는 것으로 알려진 호르몬 관련 질병을 제외한 부인과 환자 52명을 대상으로 지방조직과 혈청을 분석하였으며, 설문조사를 통하여 연령, 교육수준, 직업, 비만도, 흡연과 음주, 출산력, 수유력등을 조사하였다. 지방조직과 혈청의 PCBs와 DDE 농도는 가스크로마토그래피를 사용하여 측정하였다. 결과 : 지방조직의 경우, 13개 PCBs congeners 농도의 합은 중앙값이 48.29 ng/g, 기하평균값이 56.78 ng/g이었고, DDE 농도는 중앙값이 142.89ng/g, 기하평균값이 117.06 ng/g이었으며, 혈청의 경우는 PCBs congeners 농도의 합은 중앙값이 4.67 ㎍/L, 기하평균값이 4.85 ㎍/L이었고, DDE 농도는 중앙값이 1.75 ㎍/L, 기하평균값이 2.09 ㎍/L로 나타났다. 지방조직과 혈청의 DDE 농도 사이는 높은 상관성을 보였으나(r²=0.310, p=0,0002), PCBs는 상관성이 약한 것으로 나타났다(r²=0.029, p=0.2582). 영향요인을 범주화한 후 로그변환 시킨 지방조직과 혈청의 PCBs, DDE 평균의 차이를 분석한 결과, 지방조직의 DDE만이 출산자녀수(p=0.015), 초산연령 (p=0.014), 비만지수(p=0.035)와 연관성이 발견되었다 다중회귀분석의 결과 지방조직의 DDE는 출산자녀수가 적을수록, 초산연령이 늦을수록 증가하는 경향을 보였다. 결론 : 출산자녀수와 초산연령, 비만도가 지방조직의 DDE와 관련성을 보였으며, 또한 유기염소계 화합물의 장기간의 노출에 의한 영향을 평가하는데 있어서 혈청보다 지방조직이 더 유용한 생물지표임을 알 수 있었다. Objectives : This study was purposed to determine the levels of PCBs and DDE in adipose tissue and serum and to evaluate the relations with factors affecting these levels. Methods : We analyzed adipose tissues and sera from 52 gynecologic benign disease patients aged 27-78 years, except hormonal diseases such as breast cancer and endometriosis. We also surveyed age, education, occupation, body mass index (BMI), smoking, drinking, number of children, and duration of breastfeeding by questionnaires. Tissue and serum levels of PCBs and DDE were measured using gas chromatography. Results : The median and geometric mean levels of PCBs were 48.29 ng/g, 56.78 ng/g for adipose tissue and 4.67 ㎍/L, 4.85 ㎍/L for serum, and those of DDE were 142.89 ng/g, 117.06 ng/g for adipose tissue and 1.75 ㎍/L, 2.09 ㎍/L for serum, respectively. Adipose tissue and serum levels for DDE showed high correlation (r²=0.310, p=0.0002), but those of PCBs didn't (r²=0.029, p=0.2582). In analyses of the differences of the means of log transformed adipose tissue and serum PCBs and DDE levels for groups of potential covariates, only adipose tissue DDE levels were significantly associated with number of children (p=0.015), age at first birth (p=0.074) and BMI (p=0.035). In multiple regression analysis, adipose tissue DDE levels were significantly increased with decreasing number of children and increasing age at first birth. Conclusions : This study suggested that parity and adiposity were associated with levels of DDE in adipose tissue, and adipose tissue is a better biomarker than serum for evaluating the long-term exposure of organochlorines.

약용식물내 에스트로겐성과 항-에스트로겐성을 조사하고 항암인자를 발견하기 위하여, 본연구는 에탄올추출로 제조된 9종류의 한국산 약용식물에 대하여 재조합효모와 MCF-7 사람유방암세포주를 이용하여 스크리닝하고 비교하였다. 재조합효모를 이용한 실험결과, 7종류의 약용식물에서 에스트로겐성이 나타났고, 4종류에서 안드로겐성이 나타났다. 또한 MCF-7 사람유방암세포주를 이용한 실험결과, 8종류의 추출물이 MCF-7 세포의 성장을 억제하는 것으로 확인되었으며 비스페놀 A와 동시 처치한 경우에도 유의적으로 억제하는 것으로 나타났다. 또한 Clyeyrrhiza uralensis, Cassia tora, Syringa velutina, Zingiber officinale, Malva verticillata, Panax ginseng C.A. Meyer는 식물성 에스트로겐으로서 에스트로겐에 양성인 사람유방암세포의 증식을 유의적으로 억제시티는 흥미로운 결과가 제시되었다. 따라서 이번 연구는 한국산 약용식물이 식물성 에스트로겐과 항암인자로서 이용될 수 있으며, 에스트로겐의 활성을 조사하는데 유용하게 이용될 수 있을 것으로 사료된다. To investigate whether there are estrogenic and anti-estrogenic activities in various medicinal herbs and discover prominent chemo-preventive agents, eye screened and compared the ethanol extracts of 9 plants through the recombinant yeast assay and MCF-7 human breast cancer cell assay. In recombinant yeast assay. seven medicinal herbs showed estrogenicity, and tour extracts showed androgenecity. In MCF-7 proliferation assay. the growth of MCF-7 cells was inhibited by eight extracts before and even alter co-treatment with bisphenol A. It is interesting that the extracts of Glyeyrrhiza uralensis, Cassia tora, Syringa velutina, Zingiber officinale, Malva verticillata, and Ponax ginseng C.A. Meyer exhibited inhibitory effects as phytoestrogens in estrogen-responsive human breast cancer cells. This study suggests that some Korean medicinal herbs might be considered as phytoestrooens and be useful to further analyze those plants which contain the estrogenic effect in order to identify the active principles.
Developing a Monitoring System for Toothbrushing
Ok Su Kim,Sang Woo Kim,Ji Sun Kim,Hong Ran Choi,Ok Joon Kim 대한구강악안면병리학회 2015 대한구강악안면병리학회지 Vol.39 No.2
Proper oral hygiene is required to maintain oral health and prevent oral disease. Toothbrushing is central to proper oral hygiene. Mechanical tooth cleaning is the mainstay of plaque control. A variety of toothbrushing techniques have been developed and evaluated for their efficacy. However, these evaluations are subjective. To adequately evaluate toothbrushing objectively, a novel toothbrushing monitoring system was developed. The system involves user-monitored brushing patterns including toothbrush motions using a 3-axis gyroscope, 3-axis accelerometer, 3-axis magnetic sensor, one load-cell and Bluetooth devices. To confirm the efficacy of this toothbrushing monitoring system, eight periodontist performed tooth brushing in a dental model, and their brushing motion was monitored and recorded, and evaluated by statistical means. The proposed monitoring system can be used to aid dental care personnel in toothbrushing instruction.

In order to screen the new β-lactam antibiotics for clinical use. we were compared MIC values of various β-lactam antibiotics. We also tested the influence of pH, inoculum size, stability of antibiotics in medium and some kinds of media on MIC value. As a result, cefotaxime, cefoperazone, piperacillin, cefamandole, cephaloridine, cephapirin, cefazolin, cephalothin, cephaioylycn were scored in antimicrobial activity of MIC data.
