  • Galla Rhois is a gallnut of Rhus javanica Linne used for treatment of diarrhea, hemorrhage, cough, leukorrhea and toxic tumor etc in oriental medicine. For the evaluation of antitumor effect of Galla Rhois, activity based fractionation was done. We isolated an effective compound and identified 1,2,3,4,6-penta-O-galloyl-β-D-glucose(PGG) by photometric analysis such as NMR and MASS. Then, we studied the angiogenic activity of PGG. It showed a cytotoxicity against SK-OV-3, SK-OV-3, HT1080 with IC/sub 50/ of 50 ug/ml approximately. It also effectively inhibited proliferation of HUVEC cells treated by bFGF to 30% of control at 20 ug/ml and cell migration to 80% at 10 ug in a dose dependent fashion. Tube formation of HUVEC cells on matrigel was effectively suppressed from 2.5 ug/ml of concentration by PGG. Moreover, it effectively recovered the dysfunction of gap junctional intercellular communication in WB-F344 rat liver epithelial cells caused by hydrogen peroxide at 4 ug/ml suggesting it potently can inhibit tumor promotion. Taken together, it indicates 1,2,3,4,6-penta-O-galloyl- β -D-glucose has antiangiogenic activity.

  • This study was performed to generate basic data to establish a health promotion plan for residents of Chungcheongbuk-do by identifying characteristics of discharged patients residing in the Chungcheongbuk-do area from an In-Depth Post-Discharge Injury Survey reported by the Korea Centers for Disease Control and Prevention(KCDCP). The Report provided data on demographic characteristics, medical institution use characteristics, medical use characteristics, and disease characteristics of patients discharged from medical institutions with 100 or more beds from 2013 to 2017. The total number of Chungcheongbuk-do residents who were admitted and discharged from 2013 to 2017 was estimated to be 1,656,590, and the discharge rate was 21,089, which was higher than the national average of 13,882 in 2016. The regions where the discharge rate increased during this period include Goesan, Yeongdong, Boeun, Okcheon, Jeungpyeong, and Eumseong-gun, which are mainly rural areas. Among the patients hospitalized and discharged from hospitals outside the Chungcheongbuk-do area, the discharge rate of patients who used hospitals in Incheon/Gyeonggi areas and Daejeon/Chungnam areas increased slightly. Among the malignant tumor patients, the number of lung cancer(included trachea & bronchial cancer) patients was the highest. In addition, the discharge rate was highest for patients with respiratory diseases. This study suggests that efforts need to be made to lower the discharge rate for infection, circulatory disease, genitourinary disease, and musculoskeletal disorder patients

  • In this study, the anti-inflammatory effect of supercritical carbon dioxide selective extracts, which extract decursin and decursinol angelate, the vital active ingredients of Angelica gigas Nakai, in high yield, was measured compared to that of ethanol extracts. To measure the anti-inflammatory effect, the production of nitric oxide(NO), an inflammatory mediator, and interleukin(IL)-6 and IL-8, inflammatory cytokines, was measured. NO production was measured by Griess assay on Raw 264.7 cells induced inflammatory response by lipopolysaccharide(LPS), and IL-6 and IL-8 production was measured by enzyme-linked immunoadsorbent assay(ELISA) on human keratinocyte cell line(HaCaT) cells induced inflammatory response by tumor necrosis factor(TNF)-α. The amount of NO production was suppressed outstandingly by the supercritical carbon dioxide extracts compared to the ethanol extracts. The amount of IL-6 and IL-8 production was increased by the ethanol extracts, whereas statistically significantly inhibited by supercritical carbon dioxide extracts at the concentration of 6.25 ㎍/mL(P<0.01). Through these results, we confirmed that the supercritical carbon dioxide selective extracts of Angelica gigas Nakai could be used as an anti-inflammatory cosmeceutical material to alleviate atopic dermatitis.

  • The anti-inflammatory and antioxidant activities of the Ulva lactuca Linnaeus extracts were measured. As a result of the MTT assay of the extract, it was found that the cell viabilities were higher than 90% at all concentrations, and the cell promotion rate exceeded 100% at a certain concentration. Therefore, in all subsequent experiments, the highest concentration was set at 500 ㎍/ml. In the nitric oxide (NO) assay, one of the anti-inflammatory experiments, the Ulva lactuca Linnaeus extracts exhibited inhibitory effects of 16%, 19%, and 62% at concentrations of 5, 50, and 500 ㎍/ml, respectively, compared with the LPS-only group. In tumor necrosis factor-α (TNF-α) assay, the extracts showed inhibitory effects of 16%, 17%, and 27% at concentrations of 5, 50, and 500 ㎍/ml, respectively, compared with the LPS-only group. In the interleukin-6 (IL-6) assay, the extracts also showed inhibitory effects of 15% and 28% at concentrations of 50 and 500 ㎍/ml, respectively, compared with the LPS-only group. In the total polyphenol content assay, the extracts exhibited 8.02, 9.90, and 23.8 mg GAE/g at concentrations of 0.3, 3, and 30 mg/ml, respectively. In the ABTS assay, the extracts exhibited scavenging activities of 2.6, 12.6, and 77.3% at concentrations of 0.3, 3, and 30 mg/ml, respectively. Therefore, it is considered that Ulva lactuca Linnaeus extracts can be used as anti-inflammatory and antioxidant substances for the development of functional foods.

  • Background: The aim of this study was to investigate clinicopathologic features of type 3 gastric neuroendocrine neoplasm (NEN) by treatment modality. Methods: The Korean Society of Gastrointestinal Cancer conducted the Korean Gastroenteropancreatic Neuroendocrine Tumor Registry, a retrospective registry database of gastroenteropancreatic neuroendocrine tumors from 16 hospitals in Korea. The normal serum gastrin level range was defined as <100 pg/mL, and gastric NEN patients with normal gastrin level were selected for analysis. Results: Among 358 patients with gastric NEN, 21 (5.9%) patients were classified with type 3 gastric NEN. The median age was 53 years (range 30-74). According to the WHO 2010 classification, 13 (61.9%) patients had grade 1, and 8 (38.1%) patients had grade 2 or 3. Endoscopic treatment was performed in 14 (66.7%) patients, and surgery was performed in 7 (33.3%) patients. The tumor size was smaller in the endoscopic treatment group than in the surgery group (0.6 cm vs 1.3 cm, p=0.006). After treatment, there was one recurrence in the surgery group. Conclusion: In small size Type 3 gastric NEN, endoscopic treatment was associated with a good prognosis, compared to surgery. Thus, endoscopic treatment can be used an alternative modality in selected cases of type 3 gastric NEN.

  • This study was conducted to examine community residents' knowledge level and related factor on electronic wave in order to provide basic data for development of education and publicity program. 2,000 people, who lived in five big cities and five small and medium cities, were selected ad subjects of this study. The data were collected from May 1, 200 I to August 31, 2001. The results of this study are as follows. According to the average knowledge level of harmful affect of electronic wave on health in general characteristics, female was higher(37.40 ± 5.24 points) than male; ‘forties’ was highest(37.77 ± 5.69 points); ‘married spouse’ was high(36.84 ± 5.59 points); ‘living in small-ta-medium city’ was high(36.84 ± 5.32 points). ‘university graduate’ was highest(37.41 ± 5.32 points) in education level, ‘middle class’ was high(36.61 ± 4.96 points) in economic status, ‘professional technician’ was higher(36.68 ± 6.55 points) than other occupations in occupational type. According to the knowledge level of harmful affect of electronic wave on health in health condition by self-judgment, ‘good health condition’ was highest(36.77 ± 4.99 points). In the case of the knowledge level of those who visited medical institutions for last one year, ‘never visited’ was highest(37.19 ± 5.02 points). In the kind of medical institutions, ‘those who visited general hospital’ was highest(36.58 ± 5.63 points). In the way of knowledge obtainments of electronic wave through education and publicity media, ‘school education’ was highest(37.55 ± 5.19 points). According to the score of awareness level of disease incidence related to electronic wave, allergy and erethism was highest(57.8 points on the basis of 100 points). It appeared in order of leukemia, skin disease or skin cancer, dementia, various cancers, cataract, and brain tumor. The variables which significantly influenced knowledge level of harm of electronic wave were knowledge obtainments of electronic wave, age, economic status, daily TV watching period, sex, period of daily cellular phone use, period of working with computer, and daily VTR watching period. The knowledge of community residents concerning harmful affect of electronic wave on health is needed because people's opportunity of exposing to electronic wave is increasing. Especially, it is the demands of the times to provide information on knowledge of each equipment which generate electronic wave. The government, the product manufacturing companies, related social organizations, and education institutions must make efforts to develop the education program which is needed to make people have right knowledge and attitude.

  • Objectives: The purpose of this study was to identify the major influencing factors of breast cancer death and to suggest policy measures to promote the health of breast cancer patients. Methods: The method of this study performed statistical analysis by applying weights to 2,300 cases of breast cancer registration statistics in Korea collected in 2018 due to the relatively small number of mortality data compared to survival. Statistical processing of the collected data was analyzed using SPSS 26.0. Results: The epidemiologic characteristics of death in breast cancer patients were 31.8% in those aged 70 years or older, and the mortality rate was 5.25 times higher in patients aged 70 years or older than those aged 39 years or younger. The anatomical site code was 36.4% in C50.4~C50.6, and the mortality rate was 1.82 times higher in C50.4~C50.6 than in C50.0~C50.1. The tumor size was 40.4% and larger than 4cm, and the mortality rate was 4.53 times higher in tumors larger than 4cm than those smaller than 1cm. The degree of differentiation was 13.9% in the poorly differentiated group, and the mortality rate was 4.38 times higher in the poorly differentiated group than in the highly differentiated group. In the hormone receptor test, non-triple negative cases were 59.6%, and the mortality rate was 0.57 times lower in non-triple negative cases than in triple negative cases. As for lymph node involvement, the presence or absence of lymph node involvement was 78.8%, and the mortality rate with lymph node involvement was 1.36 times higher than that without lymph node involvement. The survival period of 13 to 24 months was the highest at 26.5%, and the average survival period was 25.68 months (±14.830). Conclusion: A policy to advance the timing of national health examinations for early detection of breast cancer is necessary. In addition, a bill for the mandatory placement of health educators in medical institutions for patients with special diseases such as breast cancer should be prepared.

  • Inhibition of gap junction-mediated intercellular communication (GJIC) has been considered as an important factor in the tumor promotion phase of carcinogenesis. Recovery effects of natural products on gap junctional intercellular communication are measured by scrape-loading and dye transfer method using Lucifer yellow after administration of phorbol-12-myristate-13-acetate (PMA) on WBF344 cells. Among tested natural products, the hexane fraction and subfractions (F-01 and F-04) of Setaria italica were relatively effective for recovery of GJIC. The hexane fraction of Setaria italica $(EC_{25},\;12.14\;{\mu}g/ml)$ and subfractions $(F-01:EC_{50},\;10.74\;{\mu}g/ml;EC_{25},\;1.58\;{\mu}g/ml,\;F-04:EC_{50},\;11.03\;{\mu}g/ml;\;EC_{25},\;3.12\;{\mu}g/ml)$ revealed dose-dependent recovery effects on GJIC. Our data show GJIC activity measurement by Lucifer yellow spread on cells can be an effective tool for the screening of natural products with possible cancer chemopreventive effects.

  • Breast cancer is the most frequent cancer of women worldwide, with considerable geographic and racial/ethnic variation. Data are generally derived from population based cancer registries in the developed countries but hospital data are the most reliable source in the developing countries. Ten years data from 1st Jan 2000 to 31st Dec 2009 of a cancer hospital in Pakistan were here analyzed by descriptive statistics to evaluate the clinicopathologic profile of local breast cancer patients. Among 28,740 cancer patients, 6,718 were registered as breast cancer. The female to male ratio was 100:2. Breast cancer accounted for 23% of all and 41% of female cancers. Some 46% were residents of Lahore, with a mean age of $47{\pm}12$ years. Less than 1% were at Stage 0 and 10%, 32%, 35% and 23% were at Stage I, II, III and IV respectively. Histopathology was unknown in 4% while 91%, 2% and 1% had invasive ductal carcinoma (IDC), invasive lobular carcinoma (ILC) and mucinous carcinoma respectively. Rare carcinomas accounted for the rest. Tumor grade 1, 2 and 3 was 11%, 55% and 34% among the known. Profile of breast cancer patients in Pakistan follows a pattern similar to that of other developing countries with earlier peak age and advanced disease stage at presentation. The male breast cancer accounts for higher proportion in the local population. Local women have higher frequency of IDC and lower frequency of ILC and DCIS, owing probably to a different risk profile. Use of hospital information systems and establishment of population based cancer registry is required to have accurate and detailed local data. Promotion of breast health awareness and better health care system is required to decrease the burden of advanced disease.

  • Cyclosporine A is an immunosuppressant commonly used for patients receiving organ transplants. Gingival overgrowth is an adverse side-effect seen in about 8-26% of patients taking cyclosporine A which have been shown to increase the DNA synthesis of gingival fibroblast at the concentration of $10^{-9}g/ml$ in vitro. Glycyrrhetinic acid is the active pharmacological ingredients of licorice which exerts steroid-like action and anti-viral activity. Oleanolic acid, which were isolated from Glechoma hederacea, has been shown to act as inhibitors of tumor promotion in vivo and to be less cytotoxic retinoic acid. This study has been performed to evaluate the effects of glycyrrhetinic acid and oleanolic acid on cyclosporine A induced cell activity in vitro. Human gingival fibroblasts were isolated from explant cultures of healthy gingiva of orthodontic patients. Gingival fibroblasts were trypsinized and transferred to the walls of microtest plates. Fibroblasts were cultured in growth medium added $10^{-9}g/ml$ cyclosporineA and $50{\mu}l/ml$ lipopolysaccharides. Cells between the 4th and 6th transfer in culture were used for this study. The morphology of gingival fibroblst were examined by inverted microscope. The effects of cyclosporine A on the time course of DNA sythesis by human gingival fibroblasts were assessed by $[^3H]-thymidine$ uptake assays. Cyclosporine A was found to stimulate DNA synthesis of human gingival fibroblast at a concentration of $10^{-9}g/ml$. In the presence of lipopolysaccharide derived from Fusobacterium nucleatum, addition of cyclosporine A results in reversal of inhibition at the concentration which normally inhibits gingival fibroblast proliferation. The cell acitivities in the presence of glycyrrhetinic acid and oleanolic acid were decreased, and increased cell acitivities by cyclosporine A were decreased by glycyrrhetinic acid and oleanolic acid at the concentration of $200{\mu}g/ml$. These results suggested that the increased cell activities by cyclosporine A modulated by glycyrrhetinic acid and oleanolic acid.
