Limy bile is a rare condition characterized by excessive precipitation of calcium carbonate in the gallbladder or bile duct. Recently we experienced two cases with obstructive jaundice in which limy bile in the common bile duct but not in the gallbladder for one case, and in the common bile duct and intra hepatic duct but not in the gallbladder for another case. The patients were treated by endoscopic sphincterotomy. Here, we report the cases and review the literature.

舊東獨地域의 私有化 方案에 관한 硏究

裵相斌,李字炯 東新大學校 1996 論文集 Vol.8 No.-

The purpose of this study is to invastigate the methods of privatization in Former East Germany. The contents of the research are summarized as follows: Trust administration agency executed the privatization of state enterprise and private-ownership of land till its task is completed on Dec. 31, 1994. Executing policies are the eviction of the land to original possessor and the method of sales to general public. But, the problems such as ambiguity of legal possession, the lack of management personnel and legal basis are imposed in the eviction method and there are the problems of low purchasing income, outflow of investment capital from capital market and rare potential to purchase the objects by the residents in the former East Germany with weak economic strength in the methods of sale. Moreover, the income from sale is low due to the factors inherent in the measures of the privatization and private management policies of trust administration agency such as remaining of economic structure of socialism, disagreement of stock-flow, credit limitation of purchaser and etc., and the sale of privatization objects is delayed. The methods to settle the above problems and foster the conversion of economic structure in the former East Germany region are as follows. In fostering methods of privatization and private-ownership of land, the problem of fund raising and the resurrection of enterprise which is the decisive weakness of free distribution should be settled. To overcome these problems, the suggestion of proportion division pattern can be theoretically referred. The core of this pattern is that the proportion of enterprise is distributed to investors and people, but government divides the proportion of enterprise which is equivalent to its own value of enterprise which supported for technical accumulation and its normalization to investors and the reamining is distributed to people not to government. This Pattern has such advantages as (1) possibility of early income supply of residents, (2) overcome of credit limitation, (3) solution of flow, stock problem, (4) relaxation of the eviction principle of tenant to original possessor and (5) availability of it to delayed negotiation of wage increase.

Dietary composition is a major determinant of cancer risk in human and experimental animals. Major and minor components of the diet may enhance or suppress the metabolism of carcinogens. In this study, the methanol layer, methanol and hexane partition layers of compositae species including Artemisia princepa var. orientalis, Arctiem lappa, Chysanthemum coronarium, Lactucascariola and Carthamis tinctorius were screened for the cytotoxicity on human hepatocellular(HepG2) and human cervix epitheloid carcinoma (HeLa) using MTT method. The methanol partition layer of Artemisia princeps var. orientalis(APMM) showed the strongest cytotoxic effects on HepG2 and HeLa cells among the other compositae species extracts. The cytotoxicity of APMM on HepG2 and HeLa cells were 94% and 95%, respectively a dose of 50㎍/ml of extracts.

당귀 추출물이 liposome 의 안정성 및 유동성에 미치는 영향

배송자,김경옥,노승배 신라대학교 자연과학연구소 1997 自然科學論文集 Vol.4 No.-

인지질 liposome의 안정성과 유동성에 대한 당귀 추출물의 영향을 알아보기 위해 여러 종류의 인지질을 만들어 실험한 결과 PC계 인지질 중 DPPC를 사용하여 인지질 liposome을 만들고, 막안 정성에 대한 영향을 calcein을 봉입한 liposome에 fluorescence self-quenching방법으로 측정하였으며, 막유동성에 대한 영향은 fluorescence polarization방법으로 P값을 측정하였고 그 결과를 다음과 같이 요약한다. 1. Phosphatidylcholine(PC)계 인지질 중 acyl chain의 C수가 14개인 dimyristoyl phosphatidylcholine(DMPC)과 C수가 16개인 dipalmitoyl phosphatidylcholine (DPPC) 및 여러 인지질의 혼합물인 egg phospatidylcholine(egg PC)을 사용하여 liposome 형성의 안정화와 막안정화에 대한 비교 실험을 하였다. 이중 liposome의 안정성이 가장 좋은 것은 egg PC였고, DPPC 그리고 DMPC의 순으로 calcein의 leakage %가 저하하였다. 2. 막 안정성에 미치는 당귀 추출물의 영향 : DPPC liposome에 당귀의 ethyl alcohol과 hexane 추출물을 가한 결과, DPPC만으로 만든 liposome보다 calcein leakage%가 감소하였으며, 추출용매에 다른 막안정화에 미치는 영향은 거의 유사하였다. 이와 같은 경향은 또한 인지질 liposome에 다른 약물을 첨가했을 경우 calcein의 leakage%정도보다 훨씬 그 영향이 탁월함을 보여주었다. 즉 당귀 추출물의 소수성 부분은 인지질 liposome의 상전이온도 이하(Tm. 41∼42℃)인 25℃에서 지질 이중 층의 rigid한 부분의 공간 속으로 깊숙히 들어가 막안정성 증가에 의한 인지질막의 condensing effect에 현저한 영향을 미침을 알 수 있었다. 3. 막 유동성에 미치는 당귀 추출물의 영향 : DPPC로 만든 liposome에 DPH로 labeling한 후 온도 증가에 따른 DPH의 fluorescence polarization값(P)의 측정에서 DPPC만으로 만든 liposome의 경우 상전이온도 이전의 gel 상태에서 상전이온도(phase transition temperature, Tm)로 되면서 P값이 현저히 저하하였으며, 당귀의 ethyl alcohol과 hexane추출물을 농도 별로 첨가했을 때는 35℃에서 시작하여 상전이온도 이전까지 현저히 P값의 저하가 일어남으로서 인지질 막의 유동성 증가를 알 수 있었으며 상전이온도 근처에서는 P값의 저하 경사가 완만해져서 온도의 증가에 따른 P값의 변화는 미미하였으나 상전이온도 이후에서는 DPPC liposome의 P값보다 당귀 추출물 첨가의 경우가 상대적으로 그 정도가 훨씬 증가된 상태였다. 이 결과에서 상전이온도 이전에서의 당귀 추출물의 막유동성 증가 효과를 읽을 수 있었고, 상전이를 전후해서 증가된 유동성은 상전이온도 이후에서는 온도 증가에 따라 미미하였으며, 오히려 상전이온도 이후에서는 DPPC만의 liposome보다 상대적으로 추출물의 농도 증가에 따른 P값의 변화가 미미하여 막유동성의 감소를 볼 수 있었다. 이상의 결과에서 당귀의 ethyl alcohol과 hexane 추출물의 소수성 부분은 DPPC의 상전이온도 이전에서는 인지질 liposome의 이중층으로 깊숙히 들어가서 막안정성과 막유동성을 증가 시키므로써 옛부터 보혈강장 및 정혈제로서 민간약제로 쓰이던 당귀 추출물이 인지질 세포막에 대한 생리적 활성을 일으킬 수 있는 촉진제로서의 가능성을 시사해 주었다고 볼 수 있다. We investigated the effects of the Angelica Radix extract on the physicochemical properties of biological membranes such as membrane stability and fluidity employing the phospholipid liposomal membranes as a biomembrane-mimetic system. The leakage of encapsulated calcein from the liposome and the fluorescence polarization of DPH labelled in the liposomal membrane were employed as the parameters of the stability and fluidity of the liposomal membrance. The results of the experiments showed that the addition of the Angelica Radix extract to the phospholipid exerted some effects stabilizing the barrier function of the membrane and increasing the fluidity of the membrane in proportion to the concentration of additive. These results suggest that the activities of the Angelica Radix extract to enhance stability and fluidity of the liposomal membrane might have implication in their biological activities.

To evaluate the antitum or activity and immune response Bujungikgibang(BJ1GB) studies were done experimentally. The results were obtained as follows: 1. BJIGB extracts exhibited a weak cytotoxicity against SK-OV-3, and SK-MEL-2 cell lines. While it showed cytotoxicity against B16-Fl0 cell line up to 30% of control at concentration of 0.5 mg/ml. 2. BJIGB extracts significantly showed inhibitoty effect on DNA topoisomerase 1 from calf thymus in a dose-dependant manner. 3. BJIGB extracts showed antiadhesive rates against A549, at 30% at 0.5 mg/ml, 60% at 1 mg/ml 4. BJIGB extracts inhibited CAM angiogenesis up to 60%. 5. BJIGB extracts prolonged life span of ICR mice bearing S-180 sarcoma cells up to 130.5%. 6. In FACS analysis, the population of helper T cell was increased weakly, while cytotoxity T cell was decreased insignificantly. 7. The production of nitric oxide in RAW cell stimulated by LPS was incresed at 0.5mg/ml or more in dose dependant fashion as compared with control. 8. Proliferation rate of splenocyte was increased at 0.5mg/ml or more a dose dependant fashion as compared with control. These results suggested that BJIGB extracts might be usefully applied for treatement of cancer and also it was nesessary to do more studies about its mechnisms.

The purpose of this study was to evaluate the effect of systemic oral health education on the improvement of knowledge levels and patient hygiene performance(PHP) for elementary school students. The randomly selected 1st and 5th grade students in a public elementary school of Taegu city were divided by education group(118 students) and non-education group(122 students). The oral health education lesson was systematically held on the education group once a month for 4 months. The questionnaire queried all the subjects about their knowledge and attitudes before and after oral health education, and PHP was also tested at the same time. Corresponding p-values were significantly considered at values less than 0.05. The obtained results were as follows: Due to the oral health education lesson, the education group of both 1st and 5th grade students came to have a higher knowledge level than the non-education group. There was high improvement of items such as toothbrushing time, toothbrushing method, cause of dental caries, treatment after tooth damage, and tongue-brushing. Therefore, these items should be educated to all the elementary school students. By increasing the knowledge level of oral health after education, the PHP index in the education group was significantly decreased in comparison to the non-education group and hence the capability of oral health education system for elementary school students can improve the knowledge level and capability of oral health management. Further study will be required to develop an easy and acceptable systemic oral health education program for elementary schools.

Endometriosis is the abnormal growth of endometrial tissue outside the uterine cavity. Endometriosis in the abdominal scar following cesarean section is very rare condition among the extrapelvic endometriosis. The frequency of abdominal wall endometriosis secondary to cesarean section is from 0.03% to 0.8% in some reports. It is difficult to diagnosed in spite of the typical symptoms. The typical symptom is aching swelling in the area of the surgical scar, which is influenced by the phases of menstruation. The definitive diagnosis is established by pathologic analysis. Surgical excision remains the treatment of choice. The majority of patients presented from 1 to 2 years after the precipitating operation. We experienced an unusual case of abdominal wall endometriosis presented over 10 years after cesarean section, who was admitted to our hospital complaining of recurrent left lower abdominal pain. So, we report this case with a brief review of the concerned literatures.

Juvenile polyp, also known as a retention polyp because they contain mucin cysts, is a relatively common hamartomatous lesion in chlidhood. It occurs in 1-2% of children and young adults; however it is uncommon in adulthood. Juvenile polyp is rare in the first year of life and is thus presumed to be acquired and not congenital. It is pedunculated, 2-3 cm in size, red-tan in colour, smooth and always shows fluid filled cystic spaces on cut surface. Histologically, Juvenile polyps are hamartomatous with distended, mucus-filled glands, often with cystic dilatation and edematous lamina propria containing abundant vasculature. The most common manifestation is rectal bleeding produced by auto-amputation of the polyp. Juvenile polyp has been considered not to be at increased risk of developing carcinoma. However, atypical epithelium is observed in some lesions, especially in larger polyps, which may give rise to adenoma and subsequent malignant transformation. Therefore the diagnosis of solitary juvenile polyp should not be made only with colonoscopy and biopsy, but should be totally resected endoscopically for pathologic evaluation. About 90% of the lesions are solitary and localized within 20cm from anal verge. In Korea, there are some reports of juvenile polyps located in the rectosigmoid colon. We report one case of juvenile polyp in adolescent that presented as a hematochezia & abdominal pain, which is located at right colon.
