본 연구의 목적은 발거된 기성 금관 수복 유구치를 대상으로 변연 적합도를 관찰 분석하는 것이다. 서울대학교 치과 병원 소아치과에서 수거한 3M사의 기성 금관 수복 유구치를 대상으로 하였다 상악 제 1유구치 42개, 상악 제 2유구치 25개, 하악 제 1유구치 37개, 하악 제 2유구치 28개를 대상으로 기성 금관의 변연에 따라 치근 절단한 후 단면을 Fine Pix S602 디지털 카메라로 촬영한 후 Kappa image base program을 이용해 두각 부위 및 임의로 20 부분의 변연 간격과 전체 기성 금관 면적 중 변연 간격의 면적이 이루는 비율을 측정하여 다음과 같은 결과를 얻었다. 1. 평균 변연 간격은 상악 제 2유구치, 하악 제 1유구치, 하악 제 2유구치, 상악 제1 유구치 순으로 높았다 (P<0.05). 2. 평균 변연 간격 면적의 비율은 치아의 종류에 관계없이 약 20%를 상회하는 값을 보였다. 3. 상악 제 1,2유구치에서는 근심면의 변연 간격이 가장 컸고, 하악 제 1유구치에서는 원심 설면, 하악 제 2유구치에서는 협면에서 변연 간격이 가장 큰 값을 보였다. Stainless steel crowns are invaluable restorative material for the treatment of badly broken down primary teeth in pediatric dentistry. But it is difficult to fit margin because selection of size is not easy and they are not adjusted for Korean children. The purpose of this study was to examine and analyze the marginal adaptation of stainless steel crown of posterior primary tooth. Marginal surface was taken by Fine Pix S602 digital camera and measurements of crown were recorded at 20 points that were randomly selected for marginal gap evaluation by Kappa image base program. 1. Mean marginal gap were large upper 2nd primary molar, lower 1st primary molar, lower 2nd primary molar, upper 1st primary molar in order(p<0.05). 2. Mean marginal surface dimension ratio was more than 20% irrespective of tooth. 3. Largest amount of marginal gap was shown at mesial surface in upper 1st, 2nd primary molar and distolingual surface in lower 1st primary molar, buccal surface in lower 2nd primary molar.

In our experiments we made use of male and female Swiss albino rats weighing about 60gm each for the sake of investigating the duodenal goblet cells which mostly bring about secretory work. The mice fed on three unbalanced diets consisting mostly of carbohydrate, protein and fat were the chief objects of study. on the 20th day after feeding, and after one or three-day fasting, Specimens were taken from the upper, middle and lower portions of the duodenum. tne specimens were fixed in 10% formalin and made into paraffin sections of 5μ and stainings were done with Hematoxylin-eosin. all of the goblet cells in each 20 crypts and villi, baths of which were cut in the axial directions were counted and averaged numbers were considered as total relative number of one animal. The results were gained as follows: 1. The relative number of the goblet cells in the duodenum of the mice fed 'on normal food averaged 22.5. these cells were found more in the villi than in the crypts. 2. The relative number of the goblet cells in the mice fed on fat was larger than the normal value, and was tne largest in the three groups fed on unbalanced diets. 3. The protein diet group was the smallest value among three groups. 4. The group's goblet cells fasting 1-day increased a little in number relative to the normal. 5. The group's goblet cells fasting 3-days increased the most in number of all groups.

In our experiments we made use of male and female Swiss albiro rats weighing about 60gm each for the sake of investigating the duodenal goblet cells which mostly bring about secretory work. The mice fed on three unbalanced diets consisting mostly of carbohydrate. protein and fat were the chief objects of study. on the 20th day after feeding, and after one or three day fasting, Specimens were taken from the upper, middle and lower portions of the duodenum the specimens were fixed in 10% formalir and made into paraffin secuions of 5μ and stainings were done with Hematoxylm-eosin. all or the goblet cells in each 20 crypts and villi, boths of which were cut in the axial directions were counted and averaged numbers were considered as total relative number of one animal.

In present study, we tested antifungal effects of 11 different kinds of compounds isolated from Phellodendri Cortex (PC), Lonicerae Flos (LF), Lonicerae Folium et Caulis (LFC) and Araliae Continental is Radix (ACR). These herbal medicines are generally applied for the treatment of inflammations. Prior to the test, antifungal effect of 70%-ethanol extracts of the medicines was examined. Results showed that the three extracts of PC, LF and LFC, but not ACR extract, inhibited Candida albicans growth, in-vitro. Among the 11 compounds, berberine and palmatine isolated from PC showed the most antifungal activity (P < 0.05). Lonicerin and loganin from LF and chlorogenic acid from LFC also retarded growth of C. albicans at high dose of 250 ㎛/ml, but their activity was much less than berberine or palmatine. However, ent-Pimara-8(14),15-diene-19-oic acid and 16α,17- Dihydroxy-ent-kauran-19-oic acid from ACR had no antifungal activity as expected. All together, these data imply that most of oriental herbal medicines having anti-inflammatory activity could have anticandidal effect, suggesting that PC, LF and LFC be effective for the treatment of septic arthritis by killing of C. albicans.
