In order to determine the knowledge of, attitudes to, and practice of housewives toward health care in a rural area, a survey with questionnaire was carried out with 87 housewives who were sampled randomly from 6 villages in Sudong Myun, from April 16th to 21st, 1979. The following results were obtained. 1. Of the housewives studied, 61.5% knew that B.C.G. is a vaccine for T.B prevention and 12.3% knew that D.P.T. is a vaccine for diphtheria, pertussis, and tetanus. 2. The vaccination rate of the children under six-year of the housewives studied was: polio 83.1%, B.C.G. 75.4%, D.P.T. 66.2%, and measles 55.4% respectively. 3. The vaccination rate was higher in children in the area near from the health subcenter than in there of the area further away. 4. Out of 87 respondants, 87.5% knew one or more methods of contraception for spacing children. These were: loop 69.0%, oral pill 66.7% and condom 14.9% respectively. 5. Out of 87 respondants, 82.2% knew the methods of contraception for sterilization. These were: laparascopy 87.5% and vasectomy 16.9%. 6. Out of 87 respondants those who had experience using contraceptive methods were 70.1% and present users were 47.1%. 7. Contraception practice rate was higher in the group of housewives having middle school education or above than those having primary school education or less. 8. Functions of the health subcenter listed by respondants were: patients care 72.4%, family planning 31.0%, vaccination 23.0%, T.B. control 3.4%, health education 3.4%, infant birth delivery assistance 1.1% respectively. 9. Housewives who knew that there is a village health voluntary worker in their own village were 63.2%(55), and 58.2% of those who knew appreciated her activities. 10. Purposes of expenditure of Myun community health development funds listed by respondants were: aid for patient care 34.5%, aid for health subcenter operation 16.1%, and aid for Myun health development 6.9% respectively. 11. It seems that both of the distance from the health subcenter and the utility rate level of the village health voluntary worker are co-related to the B.C.G. vaccination rate of children. 12. It seems that both of the distance from the health subcenter and the utility rate level of the village health voluntary worker are not co-related to the rate of contraception practice.

Atopic dermatitis (AD) is a chronic inflammatory skin disease of mainly infants and children. Currently, the development of safe and effective treatments for AD is urgently required. The present study was conducted to investigate the immunomodulatory effects of yeast-extracted β-1,3/1,6-glucan and/or Lactobacillus plantarum (L. plantarum) LM1004 against AD-like symptoms. To purpose, β-1,3/1,6-glucan and/or L. plantarum LM1004 were orally administered to AD-induced animal models of rat (histamine-induced vasodilation) and mouse (pruritus and contact dermatitis) exhibiting different symptoms of AD. We then investigated the treatment effects on AD-like symptoms, gene expression of immune-related factors, and gut microbiomes. Oral administration of β-1,3/1,6-glucan (0.01 g/kg initial body weight) and/or 2 × 10¹² cells/g L. plantarum LM1004 (0.01 g/kg initial body weight) to AD-induced animal models showed significantly reduced vasodilation in the rat model, and pruritus, edema, and serum histamine in the mouse models (p < 0.05). Interestingly, β-1,3/1,6-glucan and/or L. plantarum LM1004 significantly decreased the mRNA levels of Th2 and Th17 cell transcription factors, while the transcription factors of Th1 and Treg cells, galactin-9, filaggrin increased, which are indicative of enhanced immunomodulation (p < 0.05). Moreover, in rats with no AD induction, the same treatments significantly increased the relative abundance of phylum Bacteroidetes and the genus Bacteroides. Furthermore, bacterial taxa associated with butyrate production such as, Lachnospiraceae and Ruminococcaceae at family, and Roseburia at genus level were increased in the treated groups. These findings suggest that the dietary supplementation of β-1,3/1,6-glucan and/or L. plantarum LM1004 has a great potential for treatment of AD as well as obesity in humans through mechanisms that might involve modulation of host immune systems and gut microbiota.

배경 : Anorexia-cachexia syndrome은 말기 암 환자에서 흔한 증상이며, 암 환자의 주린 사망 원인이 되기도 한다. 이들 증상들은 주로 암 세포 성장과 암세포에서 분비되는 cytokines이 중요한 역할을 한다고 한다. 일부 의사들은 비타민 C가 선택적인 항암 효과를 가지고 있을 뿐만 아니라 여러 가지 말기 암 환자에서 임상 증상을 호전시키는 데 도움이 된다고 보고하였다. 이에 저자 등은 비타민 C가 anorexia-cachexia syndrome을 유발시키는 기전 중의 하나인 사이토카인에 어떤 영향을 주는 지를 알아보고자 한다. 방법 : 2002년 3월 1일부터 2002년 8월 31일까지 국민건강보험공단 일산병원 가정의학과에 입원한 환자 49명을 대상으로 22명은 비타민 C를 1주일동안 지속적으로 10 g을 정맥 주사하였고, 나머지 27명은 비타민 C를 주사하지 않았다. 대상이 된 환자의 비타민 C를 주기 전과 주고 1주일 지난 후의 혈액을 채취하여 cytokine의 변화가 있는 지를 wilcoxon rank sum test를 이용하여 비교분석하였다. 결과 : 대상이 된 총 49명의 환자 중 22명(남자 12명, 여자 10명)이 비타민 C를 사용하였고, 27명(남자18명, 여자 9명)이 비타민 C를 사용하지 않았다. 비타민 C를 사용한 환자에서 $IL-1{\beta}$는 사용 전에는 $6.19{\pm}5.47$이고, 사용 1주일 후에는 $8.76{\pm}5.72$로 $2.94{\pm}7.29$만큼 증가하였고, IL-6는 사용 전에는 $3.07{\pm}8.09$이고 사용 1주일 후라는 $1.31{\pm}2.36$로 $-1.57{\pm}7.96$만큼 감소하였으며, $TNF-{\alpha}$는 사용 전에는 $2.74{\pm}14.24$이고 사용 1주일 후에는 $0.50{\pm}2.00$로 $-4.13{\pm}18.74$만큼 감소하였다. 비타민 C를 사용하지 않은 환자에서는 $IL-1{\beta}$는 사용 전에는 $1.00{\pm}2.19$이고, 사용 1주일 전에는 $17.16{\pm}81.55$로 $16.50{\pm}81.71$만큼 증가하였고, IL-6는 사용 전에는 $2.50{\pm}3.58$이고, 사용 1주일 후에는 $6.49{\pm}12.01$로 $4.11{\pm}12.14$만큼 증가하였으며, $TNF-{\alpha}$는 사용 전에는 $1.19{\pm}2.98$이고, 사용 1주일 후에는 $1.27{\pm}1.52$로 $-0.07{\pm}4.36$만큼 감소하였다. 비타민 C를 사용한 환자와 사용하지 않은 환자에서 사이토카인 변화는 모두 비타민 C를 사용한 환자가 사용하지 않은 환자보다 감소하거나 더 적게 증가하였지만 각각 통계학적인 의미는 없었다($IL-1{\beta}$에서는 P=0.06, IL-6에서는 P=0.166, $TNF-{\alpha}$에서는 P=0.54). 결론 : 비타민 C 사용여부에 따른 cytokines의 변화는 비록 통계학적인 차이는 없지만 비타민 C를 사용한 환자의 cytokines이 모두 사용하지 않은 환자에 비해 감소하였음을 보였다. 비타민 C는 부작용이 거의 없는 안전한 약으로서 말기 암 환자에서 비타민 C사용은 임상 증상을 호전시키는 데 도움이 될 것이라 생각된다.

A survey of 113 children, aged 4 to 6 years, of the San Cheon a day care center, located in the upland, over populated, poor area of Seoul City, was conducted from July 28 to September 6, 1982, to investigate the dietary and nutritional status, and prevalence of parasitic inpection. House size was 10.1 Pyung; number of households per house, 3.1; number of family member per household, 4.8; and number of family members living together per room, 3.7; on the average. Only 49% of households possess own houses and the others live in the rented houses. About 40% of mothers were engaged income-producing activities within or outside of the home. Mean values of height, weight, arm circumference, girth of chest, and girth of head ranged from 98.4 to 102.2% of KIST mean. However, 13% of the subjects were assessed as undernutrition for 'weight for height'. Mean value of hemoglobin was $12.9{\pm}2.9\;g/dl$ and mean hematocrit value was $35.2{\pm}5.5%$; 17.9% of the subjects were proven to be anemic according to the criteria of the WHO. The positive prevalence of parasitic inpection was 3.3%, significantly lower than that observed in any other area, probably because of community parasitic control project. Intakes of energy and nutrients except thiamin and ascorbic acid were far below RDAs. Carbohydrates for energy provided 71. 2 to 73.8% of total energy intake; protein accounted 11.3 to 12.2%; fat provided 14.5 to 16.6%. Energy intake was divided among breakfast, lunch, evening meal and snack, on the average, in a percentage of 22.0; 23.4; 24.4; 30.2. There was significant correlation between pattern of food consumption and nutrient intakes. The nutrient intakes and quality of foods were highly correlated to the maternal factors, especially mother's educational level. The study suggested that development of nutrition guides for mother and children would be needed to improve nutritional status of those young children.

UHRF2 is a member of the ubiquitin plant homeo domain RING finger family, which has been proven to be frequently up-regulated in colorectal cancer cells and play a role as an oncogene in breast cancer cells. However, the role of UHRF2 in glioma cells remains unclear. In this study, we performed real-time quantitative PCR on 32 pathologically confirmed glioma samples (grade I, 4 cases; grade II, 11 cases; grade III, 10 cases; and grade IV, 7 cases; according to the 2007 WHO classification system) and four glioma cell lines (A172, U251, U373, and U87). The expression of UHRF2 mRNA was significantly lower in the grade III and grade IV groups compared with the noncancerous brain tissue group, whereas its expression was high in A172, U251, and U373 glioma cell lines. An in vitro assay was performed to investigate the functions of UHRF2. Using a lentivirus-based RNA interference (RNAi) approach, we down-regulated UHRF2 expression in the U251 glioma cell line. This down-regulation led to the inhibition of cell proliferation, an increase in cell apoptosis, and a change of cell cycle distribution, in which S stage cells decreased and G2/M stage cells increased. Our results suggest that UHRF2 may be closely related to tumorigenesis and the development of gliomas.

편도적출은 우리 이비인후과 임상에서 평소에 다반사로 행해지는 수술의 하나이라 하겠다. 수술술기의 개량, 마취의 발달과 더불어 각종 항생제의 발견등은 편도 적출술에 따르는 여러 가지 합병증을 감소시켰지만, 이중 수술중 또는 수술후에 왕왕 당하는 출혈문제는 가장 흔한 합병증의 하나이며 술자에게는 골치거리의 하나이기도 하여 아직껏 국내외에서 그 보고가 끊어지지 않고 있다. 특히 본증례에서와 같이 본태성 질환으로 인한 출혈의 해결에 있어서는 더욱 복잡곤란한 문제가 많을 것으로 생각된다. 혈우병은 1950년대에 이르러 각 Factor가 발견되어 현재는 혈우병 A.B.C.로 나뉘고 있다. 본증례는 11세의 남아로서 편도 척출술전에는 혈우병의 유무가 인지 못되었던 예로서 수술후 수술창에서 계속되는 출혈로 혈액응고장애를 가진 질환이라고 생각되어 여러 가지 검사결과 P.T.C의 결여로 오는 혈우병 B란 진단을 얻었기에 교훈적이고 귀중한 체험을 얻었다고 생각되어 보고하는 바이다. 환자는 수차의 수혈과 비인강탐폰 등의 방법으로 겨우 지혈되어 수술 20일만에 수술창이 치유되어 퇴원하였다.

Sex-related genes expressed in vitellogenic ovaries of the giant tiger shrimp, Penaeus monodon, were identified by an EST approach. A total of 1051 clones were unidirectionally sequenced from the 5 terminus. Nucleotide sequences of 743 EST (70.7%) significantly matched known genes previously deposited in the GenBank (E-value <$10^{-4}$) whereas 308 ESTs (29.3%) were regarded as newly unidentified transcripts (E-value >$10^{-4}$). A total of 559 transcripts (87 contigs and 472 singletons) were obtained. Thrombospondin (TSP) and peritrophin (79 and 87 clones accounting for 7.5 and 8.3% of clones sequenced, respectively) predominated among characterized transcripts. everal full length transcripts (e.g. cyclophilin, profillin and thioredoxin peroxidase) were also isolated. A gene homologue encoding chromobox protein (PMCBX, ORF of 567 nucleotides encoding a protein of 188 amino acids) which is recognized as a new member of the HP1 family was identified. Expression patterns of 14 of 25 sex-related gene homologues in ovaries and testes of P. monodon broodstock were examined by RT-PCR. Female sterile and ovarian lipoprotein receptor homologues were only expressed in ovaries whereas the remaining transcripts except disulfide isomerase related P5 precursor and adenine nucleotide translocator 2 were higher expressed in ovaries than testes of P. monodon broodstock. A homologue of ubiquitin specific proteinase 9, X chromosome (Usp9X) revealed a preferential expression level in ovaries than testes of broodstock-sized P. monodon (N = 13 and 11, P<0.05) but was only expressed in ovaries of 4-month-old shrimp (N = 5 for each sex).

Neurokinin B (NKB) and neurokinin B related peptide (NKBRP) belong to tachykinin peptide family. They act as a neurotransmitter and/or neuromodulator. Mutation of NKB and/or its cognate receptor, NK3R resulted in hypogonadotropic hypogonadism in mammals, implying a strong involvement of NKB/NK3R system in controlling mammalian reproduction. Teleosts possess NKBRP as well as NKB, but their roles in fish reproduction need to be clarified. In this study, NKB and NKBRP coding gene (tac3) was cloned from Nile tilapia and sequenced. Based on the sequence, Nile tilapia NKB and NKBRP peptide were synthesized and their biological potencies were tested in vitro pituitary culture. The synthetic NKBRP showed direct inhibitory effect on the expression of GTH subunits at the pituitary level. This inhibitory effect was confirmed in vivo by means of intraperitoneal (ip) injection of synthetic NKB and NKBRP to mature female tilapia (20 pmol/g body weight [BW]). Both NKB and NKBRP had no effect on the plasma level of sex steroids, E2 and 11-KT. However, NKBRP caused declines of expression level of GnRH I, Kiss2 and tac3 mRNAs in the brain while NKB seemed to have no distinct effect. These results indicate some inhibitory roles of NKBRP in reproduction of mature female Nile tilapia, although their exact functions are not clear at the moment.

Objectives : To assess the seroprevalence and risk factors of toxoplasmosis in high school students in Cheju Province, Korea. Methods : A total of 4,570 high school students from 18 schools in Cheju Province were investigated for Toxoplasma gondii antibodies(IgG) by enzyme linked immunosorbent assay (ELISA). Risk factors for toxoplasmosis, such as place of residence, type of house, contact with cats and other pets, and rare meat consumption, were examined by questionnaire. Results . The overall antibody positive rate was 5.5% and ranged from 2.6 to 11.5% by school. There was no significant difference between males and females. Statistical analyses of the questionnaire data indicated that the risk factors for seropositivity were: (1) birth place (Cheju/others), (2) place of residence (rural/urban), (3) dietary habits (vegetarian/non vegetarian), (4) eating rare meat, (5) exposure to pets and (6) hepatitis B. Conclusion : We confirmed that the prevalence of the anti-Toxoplasma gondii antibody in a population of high school students in Cheju Province was to the previously reported prevalence.
