To evaluate the in-vivo effects of mitomycin-C-polyglycolic acid composite(MMC-PGA) the disk: shaped composite were implanted into the peritoneal cavity of the Sprague-Dawley rats. The pathologic changes were examined at various time points up to 12 weeks. Initially the soft tissue around the inserted disks showed capillary congestion at 3 days. Inflammatory infiltrates with foreign body giant cells appeared from the 2nd week and reached peak response at 6-8 weeks. These reaction diminished prominently at 12 weeks. No specific pathologic change was found in the liver, the kidneys, and the heart. The above results suggest that the MMC-PGA composite can serve as a new device for intraperitoneal chemotherapy of various types of cancers.

The purpose of this study was to find out a scheme to reduce a job stress of dental technicians and to increase and operation efficiency with the improvement of working environment. The method of study was by the questionnaire-survey from dental technicians working in the dental clinics or the dental department of clinics or hospitals in DaeguㆍKyungbuk, for the period of Jul 1 - Aug 2, 2002. Here 246 ones answered relative faithfully among 300 questionnaires were used. The results of study were as follows; 1. In the stress degree of dental technicians, stress by work load, job conflict, and pay showed significant results in crown jobs(p<0.001), long-time workers(p<0.0001) and discontinuing workers(p<0002), and technicians(p<0.007), respectively. 2. From looking over facility for improvement of working environment conditions of dental technicians, it's found that most of illumination and noise protection facilities and a part of respiratory protection facilities are not installed for dental technicians satisfactorily. 3. In relationship between installation for work environment improvement and stress, technicians who worked in good environment condition had lower stress degree than workers with unsatisfied work enrironment in most of all characteristics. Especially the result showed that installation for respiratory system is very important for reduction of factors causing stresses.

송준영,이규석,정재봉 啓明大學校 醫科大學 1994 계명의대학술지 Vol.13 No.4

Epidermal growth factor(EGF) and transforming growth factor alpha(TGFα) are important keratinocyte mitogens. Their effect are mediated by a cell membrane receptor(EGFR), quantitive and qualitive abnormalities of which may be responsible for deranged keratinocyte proliferation and differentiation. We have therefore examined EGFR expression immunohistochemically in a variety of benign and malignant epithelial neoplasms using monoclonal antibodies to the extracellular and intracellular receptor domains, In benign tumor(seborrheic keratosis), there was an ordered pattern of EGFR expression. In malignant tumors(basal and squamous cell carcinoma), there was loss of membrane labelling and cytoplasmic accumulation of the receptor. In premalignant prolifertation(Bowen's disease), there was loss of membrane receptor with absent cytoplasmic EGFR. In slot-blot analysis, the levels of EGFR mRNA in sguamous cell carcinoma and basal cell carcinoma revealed 3 fold elevation when compared to normal skin. We suggest that dysregulation of the EGFR may be important in the development of cutaneous epithelial malignancies.

계승영구치가 선천적 결손된 유치의 치근 흡수

유치의 정상적인 치근 흡수는 계승 영구치의 맹출 압력으로 단핵구 세포가 방출되어 파골세포로의 분화가 촉진되어 일어나며, 계승 영구치의 맹출 경로를 따라 유치의 치근이 흡수되어서 유치가 탈락하게 된다. 계승 영구치가 선천적으로 결손되었을 때에도 유치의 치근은 흡수될 수 있는데, 유치의 비정상적 치근흡수는 외상이나 염증, 교합압의 증가, 지지조직의 약화 등으로 발생할 수 있다. 치아의 선천적 결손은 인간에서 가장 흔한 발육이상이며, 영구치가 결손되었을 때 유치는 만기 잔존할 수 있다. 영구치의 선천적 결손은 전신질환이 있는 경우뿐만 아니라 국소적 원인이나 인류 진화에 따른 영향 등에 의해서도 발생한다. 이 증례들은 계승 영구치가 선천적으로 결손된 어린이에서 유치의 치근이 비정상적으로 흡수된 경우로 계승 영구치가 결손 된 유전치와 유견치, 유구치의 치근이 1/2 ~ 3/4정도까지 흡수 되었으며 흡수 부위는 불규칙적인 형태를 보였다. 원인으로는 흡수에 감수성이 높은 유치의 치주인대, 그리고 성장에 따라 증가되는 저작근육과 저작력, 혼합치열기에 유발되는 비정상적 교합 등을 생각할 수 있다. 계승 영구치가 결손된 유치가 비정상적인 치근 흡수를 보이는 경우에 유치는 유지될 수도 있지만, 여러 요인에 의하여 탈락될 경우에는 공간을 유지 할 것인지 판단해야 하며, 향후 보철치료나 교정치료를 요하므로 장기적인 치료계획을 수립해야 한다. Root resorption of primary teeth usually occurs as the succeeding permanent teeth erupt, which induces differentiation of the hemopoietic cells into osteoclasts. Their root resorption pattern reflects the eruption path of the succeeding permanent teeth, and eventually the primary teeth shed as their succeeding permanent teeth erupt. Even when a permanent tooth germ is congenitally missing, root resorption of the corresponding primary tooth may still occur due to various factors, such as inflammation, traumatic occlusal force, and weakness of periodontium etc. Such congenital missing of permanent teeth is a commonly observed phenomenon in human be ing, and it often accompanies delayed retention of primary teeth. The etiologic factors for congenital missing in elude not only systemic diseases, but also local factors and human evolution process. In the radiographs of the cases in this report, the primary teeth without succeeding permanent teeth show pathologic root resorption. Root resorption progressed about 1/2~3/4 of the roots, and the surfaces of the resorption area were irregular. Considering high susceptibility of the periodontal ligament of primary teeth to root resorption, pathologic root resorption of primary teeth with delayed retention can be explained by the increased masticatory muscle force and abnormal occlusion developed during the mixed dentition. When the primary teeth without succeeding permanent teeth are lost, decision for space maintenance is required and long-term treatment plan for further prosthetic or orthodontic treatment should be establsihed.
