Background: The purpose of this study is to find out to how much influence religion had on the quality of life in patients admitted to the hospice facility at Saemmul's House. Terminal cancer patients were assessed one to two weeks after admittance to Saemmul's House. Metohd: The subjects of this study were numbered at 75 patients and were admitted to the hospice facility at Sammul's house between January 2002 and July 2002. The data regarding quality of life was collected using a questionnaire prepared by the sammul Hospice and were analyzed by means of ANOVA and T-test. Result: As a result of this study, there was no noticeable difference in quality of physical, psychosocial life between the patients with conviction of salvation and the other patients. However, it shows that the former enjoyed a higher spiritual quality of life than the latter. In case of baptized patients and unbaptized patients, there were no differences in terms of physical and psychosocial quality of life, but the baptized patients demonstrated a higher spiritual quality of life. After admittance, patients were grouped by duration of conviction of salvation I.e., those that believed more than 5 years and those that believed less than 5 years. In terms of physical, psychosocial quality of life, there was little difference between the two groups. However, those who believed more than 5 years demonstrated a higher spiritual quality of life. However, there was no difference in quality of life among patients, regardless of their belief in God, after receiving spiritual care at the hospice. Conclusion: We got a few conclusions in accordance with result gained by this study. First, spiritual support is very important to improving quality of patients' lives in hospices. Second, hospice programs are needed keenly and spiritual support for patients from trained experts is needed 24 hours a day. Third, because trained experts(ministry) are urgently needed to lend spiritual support, hospice courses must be taught at all colleges of theology. Fourth, a hospice program must provide a proper atmosphere that can give spiritual support and therefore all hospices must build such as environment. Fifth, a tool for spiritual support of hospice must be developed.

The aim of this study was to assess the people's need for visiting health services in a rural area. In recent years, the great concern for the visiting health services has aroused in Korea. Stratified cluster sample for a household survey was used to select 1,255(8.4%) Households from Yonchon county. This study was undertaken from July 26 to August 7 in 1993. Medically defined need, usually expressed by the prevalencies or rates of specific disease, was evaluated with the use of criteria established by medical and nursing professors and expressed by the percent of specific objects for the visiting health services. Perceived need represented by the acceptability for the visiting services and willingness to paying for it, also, evaluated. The major results were as follows : 1. Of the 348 patients with hypertension, 201 were the non-compliant patients, the rate of the non-compliant hypertension patients in 4,577 study population was 7.4%. 2. Of the 141 diabetic patients, 73 were the non-compliant patients, the rate of the non-compliant hypertension patients in 4,577 sample population was 2.7%. 3. The number of patients with severe musculo-skeletal disease was 24, the rate was 0.9% above the age 30. 4. Of the 514 elderly, 33 were the elderly without any family member, the rate was 8.4%. Those with severely decreased activity of daily living were 13. 5. Infants with high risks were 12, pregnant women and neonates were 5, patients discharged within 1 week and with special equipments such as peritoneal dialysis, stoma, TPN etc. were 17, and patients with cancer were 5. Total number of the objects needed visiting health services was 752(18.43%) of the 4,577 study population. Perceived need evaluated were as follows; The acceptance rate of visiting health services was 74.9%, The kinds of visiting health services such as family health protection and promotion, early detection of hypertension, physiotherapy, health education and counseling were needed in the order of high rate The price willing to pay for visiting health services per visit was about 3,000-5,000Won. In conclusion, Visiting health services programme to be developed should have priority to the prevention of complications of chronic disease such as hypertension, diabetes milletus, elderly disease and health promotion.

Probiotics have many effects such as antihypertensive, prevention of cancer, antioxidation, reduction of dermatitis symptoms, improvement of mineral absorption, reduction of allergic symptoms, and decrease of cholesterol, However, the main role of probiotics is that they balance intestinal microbials proportion. L. acidophilus is one of probiotics and microflora in intestine. It has an acidification activity, aroma production, texture formation and probiotics properties. We studied on the roles of L. acidophilus in mice. In this study, body weights of mice were decreased when administration of L. acidophilus ($1{\times}10^{10}$ CFU) and swimming ability has been raised than a normal group after feeding on L. acidophilus ($1{\times}10^{10}$ CFU). After taking L. acidophilus ($1{\times}10^{10}$ CFU), total white cells were increased than a normal group; hemoglobin and thrombocytes were increased. The level of cholesterol and triglyceride were decreased in blood analysis. We knew L. acidophilus is related to innate immune system. We found out the secretion of cationic peptide was increased in the Lysoplate assays as a result of L. acidophilus ($1{\times}10^{10}$ CFU) administration. Appearance rate of lysozyme was also increased than the normal group on an immunohistochemistry stain. We confirmed L. acidophilus contributes to host health through innate immune system stimulation. L. acidophilus more than $1{\times}10^{10}$ CFU are thought to be beneficial for the host health and prevention of intestinal diseases in field condition.

Much of the interest on the chemopreventive properties of herbs and plants has been raised, whereas little is regarding to anti-tumor effect of farming and aquatic products. In the present study, the anti-tumor effect of hot-water extract of a seaweed, BLC (Sargassum fulvellum) and BLC/HEN egg was investigated using MCF-7 cells in vitro and in vivo systems. We found that the BLC extract and BLC/HEN egg inhibited cell proliferation in a dose-dependent manner, which might be mediated through up-regulation of p53. Furthermore, this test compound can directly induce apoptosis in MCF-7 cells, which might be mediated through up-regulation of a pro-apoptotic Bax protein and down-regulation of a anti-apoptotic Bcl-2 protein, not by immune system. Nude mice bearing established breast tumors (with exogenous estradiol) were treated with BLC extract and BLC/HEN egg. Treatment BLC extract and BLC/HEN egg caused a 42% and 71% inhibition of tumor growth, respectively. Both agents caused a significant inhibition of volume and weight growth of estrogen independent human breast tumors established from MCF-7 cells. Our results suggested that BLC extract and BLC/HEN egg have the efficacious effect of human breast cancer not only in vitro but also in vivo.

Cytochrome P4501B1(CYP1B1) is known to be inducible by xenobiotic compounds such as policyclic aromatic hydrocarbon(PAH) and dioxins such as 2,3,7,8-tetrachloro-dibenzo-p-dioxin(TCDD). And these induction of CYP1B1 is also regulated by many categories of chemicals. In order to investigate the effects of several chemicals on CYP1B1 gene expression in Hepa-I and MCF-7 cells, 5' flanking DNA of human CYP1B1 was cloned into pGL3 basic vector containing luciferase gene, and then transfected into these cells. After treatment of chemicals, the luciferase activity was measured. CYP1B1 enzyme metabolize PAHs and estradiol. CYP1B1 metabolize estradiol to 4-hydrozyestradiol that is considered as carcinogenic metabolite. Recent industrialized industrialized society, human has been widely been exposed to widespread environmental contaminants such as PAHs(polycyclic aromatic hydrocarbon) that are originated from the imcomplete combustion of hydrocarbons. PAHs are known to be ligands of the AhR(aryl hydrocarbon receptor). Induction of cytochrome P4501B1(CYP1B1) in cell culture is widely used as a biomarker for PAHs. Therefore we have studied the effect of PAHs in the human breast cancer cells MCF-7 to evaluate bioactivity of PAHs. We have used the United State of America EPA selected 13 different PAHs, PAHs mixtures and extracts from environmental samples to evaluate the bioassay system. We examined effects of PAHs on the CYP1B1-luciferase reporter gene and CYP1B1 mRNA level. Benzo(k)fluoranthene and dibenzo(a, h)anthracene showed strong response to CYP1B1 promoter activity stimulation, and also CYP1B1 mRNAs increase in MCF-7 cells in a concentration-dependent manner. RT-PCR analysis indicated that PAHs significantly up-regulate the level of CYP1B1 mRNA. Some flavonoids such as genistein, daidzein, chrysin, naringenin and morin were also investigeted. These flavonoids decreased B(k)F infuced luciferase activity at low concentration. But, these flavonoids exhibited stimulatory effect at high concentration.

최근 급속한 경제 성장과 함께 국내 산업기반 시설과 국민생활기반 시설과 같은 국내 건축물 고급화로 천연석재 마감재 수요 증가와 동시에 국내 채석장 수도 증가하고 있다. 이에 따라 채석장의 증가와 함께 채석장에서 발생하는 환경오염으로 주변 지역 피해가 주목받고 있다. 예를 들자면, 채석장으로부터 흘러나온 석면이나 분진이 응집되어 생기는 고체와 같은 발암물질로부터 지역 주민들은 위협받고 있다. 특히 석면에서 방출되는 라돈가스는 지구상 어디에나 존재하고 토양과 암석에서 방출되는 자연방사능 물질로 흡연에 이어 폐암 발병의 주요 원인이다. 실내 환기량이 부족한 상태에서 실내공기 오염원이 지속적으로 순환될 경우, 두통, 현기증 등의 인체반응이 나타나면서 거주자의 건강을 위협하기 때문에 유해물질 저감이 시급한 실정이다. 주택 실내공기질의 오염원 중 하나인 라돈가스의 경우 방출원에서 반감기를 거쳐 계속해서 방출되는 특성을 가지고 있으므로 완벽한 제거보다 방출원에 대한 제어가 필요하다. 라돈가스와 같은 유해물질 흡착 성능을 가진 버미큘라이트의 첨가율을 10%로 고정하고 현무암 폐석을 50, 60, 70, 80% 첨가하여 실험을 진행하였다. 실험의 결과로 'KS F 4035,기성 테라죠'에 의거하여 종합적으로 고려할 때 현무암 폐석의 첨가율 70%에서 최적의 인조석재를 제조할 수 있는 것으로 판명되었다.

Purpose: Abnormalities in the p53 gene are regarded as the most consistent genetic abnormalities detected in head and neck squamous cell carcinogenesis. Two new members of the p53 gene family, p73 and p63 have recently been identified. They share considerable sequence homology with p53 in the transactivation, DNA binding, and oligomerization domains, indicating possible involvement in carcinogenesis. Disruption of the homeostatic balance between proliferation and apoptosis is widely believed to contribute to human oral carcinogenesis. The aim of this study was to analyze expression of p63 in squamous cell carcinogenesis and to compare with immunochemical markers representing cell proliferation and apoptosis. Materials and Methods: Using the Syrian hamster oral cancer model, the fraction of apoptotic (apoptotic index-AI), proliferating (mitotic index-MI) and p63 expressing keratinocytes were examined at normal, dysplastic and malignant oral epithelium using the TUNEL assay, PCNA and p63 immunostaining. Results: p63 significantly increased between normal and dysplastic epithelium and between dysplastic and malignant epithelium. PCNA significantly increased between normal and dysplastic epithelium and between normal and malignant epithelium. However, increase between dysplastic and malignant epithelium, though still increasing, was not statistically significant. The percentage of TUNEL positive cells increased from normal to dysplastic epithelium and returned to normal keratinocyte level in the malignant epithelium. However, differences between tissue types were not significant. The ratio of MI:AI increased significantly only in the dysplastic-malignant epithelial transition. The increase of p63 expression closely reflected the change in the MI:AI ratio during oral carcinogenesis. Conclusion: The p63 may be associated with the regulation of epithelial proliferation and apoptosis in DMBA-induced hamster buccal pouch squamous cell carcinogenesis. Further study is required to investigate which p63 isoforms are involved in hamster buccal pouch carcinogenesis.

This study was to evaluate the expression of vascular endothelial growth factor receptors (VEGFRs) in tumor and stromal cells of tougue squamous cell carcinoma (SCC). We also wanted to characterize the differences, from the angiogenic aspect, between cancer-associated stromal cells and non-malignant stromal cells. Paraffin-embedded tumor specimens from eleven patients with tongue SCCs were studied. Immunohistochemical staining for VEGFR-1,-2, and -3 was performed on the tumor cells, stromal fibroblasts and tumor-associated macrophages of the specimens. The expression of all 3 receptors was detected in the tumor cells themselves of the biopsy specimens. All 3 receptors were also expressed on stromal cells, except that VEGFR-2 was not expressed in stromal fibroblasts. In radical excision specimens, the staining intensity for VEGFR-1, -2 in the tumor cells and VEGFR-1,-3 in the tumor-associated macrophages was significantly lower than that in the biopsy specimens (P < 0.05). By using the general marker of fibroblast and macrophage, 5B5 and CD68, respectively, we performed double immunofluorescence staining for 5B5 and each VEGFR in the stromal fibroblasts and for CD68 and each VEGFR in the tumor-associated macrophages of the radical excision specimens. We used 4 cases of fibroma and 4 cases of chronic inflammation tissue as the controls. It was found that only each marker was expressed in the control group, however, 5B5/VEGFR-1 and 5B5/VEGFR-3 in the stromal fibroblasts, and CD68/VEGFR-1 and CD68/VEGFR-3 in the tumor-associated macrophages were double stained in the radical excision specimens. Although our study used small number of specimens, the results of our study showed that in tongue SCC, in association with the angiogenesis, the stromal cells showed the activated phenotype and this was different from the nonmalignant stromal cells.
