  • 목 적: 일중선호도는 하루 중 어느 시간대에 각성도가 높고 활기찬 지에 대한 경향으로 아침형-저녁형이라고도 알려져있다. PER3 유전자는 일중선호도에 영향을 주는 것으로 알려져 왔다. 본 연구에서 우리는 젊고 건강한 피험자들에서 환경과 혼란요인들을 통제하고 PER3 유전자 다형성과 일중선호도간에 연관을 연구하였다. 방 법: 연구에 참여한 대상자는 299명의 의과대학생들(남자 299, 여자 191명)이며 평균연령은 22.9세였다. 일중선호도는 13개 문항의 Composite Scale for Morningness (CSM)로 측정하였다. PER3 VNTR(rs57875989)의 유전자형분석은 중합효소연쇄반응법을 사용하여 이루어졌다. 양측검정으로 유의수준은 p<0.05로 하였다. 결 과: 전체 대상자에 대한 CSM 점수는 31.90${\pm}$6.39 (평균${\pm}$표준편차)였다. 남녀간에 CSM 총점에 유의한 차이는 없었다. PER3 5R/5R에서 CSM 점수가 높은 경향을 보였으나, PER3 VNTR(rs57875989) 유전자형과 대립유전자에 따른 CSM 점수의 유의한 차이는 없었다. 결 론: 본 연구는 젊은 건강한 한국인에서 PER3 V- NTR과 일중선호도간의 연관을 입증하지 못했다. 향후 보다 대규모의 피험자들을 대상으로 PER3의 여러 유전자들에 대해 다형성과 일중선호도간의 연관에 대한 연구가 필요할 것으로 생각된다.

  • This study aimed to analyze the expression and clinical significance of cyclin G2 (CCNG2) in thyroid carcinoma and the biological effects of CCNG2 overexpression in a cell line. Immunohistochemistry and Western blotting were used to analyze CCNG2 protein expression in 63 cases of thyroid cancer and normal tissues to allow the relationship with clinical factors to be assessed. CCNG2 lentiviral and empty vectors were transfected into the thyroid cancer K1 cell line. Reverse transcription-polymerase chain reaction (RT-PCR) and Western blotting were applied to detect the mRNA and protein levels of CCNG2. MTT assay and cell cycle were also conducted to assess the influence of up-regulated expression of CCNG2 on K1 cell biology. The level of CCNG2 protein expression was found to be significantly lower in thyroid cancer tissue than normal tissues (P<0.05). Western blot: The relative amount of CCNG2 protein in thyroid cancer tissue was respectively found to be significantly lower than in normal tissues (P<0.05), correlating with lymph node metastasis, clinic stage and histological grade (P<0.05), but not gender, age or tumor size (P>0.05). Loss of CCNG2 expression correlated significantly with poor overall survival time on Kaplan-Meier analysis (P<0.05). The results for biological functions showed that K1 cell transfected CCNG2 had a lower survival fraction, a greater percentage in the G0/G1 phases, and lower cyclin-dependent kinase 2 (CDK2) protein expression compared with K1 cells non-transfected with CCNG2 (P<0.05). CCNG2 expression decreased in thyroid cancer and correlated significantly lymph node metastasis, clinic stage, histological grade and poor overall survival, suggesting that CCNG2 may play important roles as a negative regulator in thyroid cancer K1 cells by promoting degradation of CDK2.

  • The objective of this study was to evaluate the effect of exogenous ghrelin on the behaviors, weight gain, and feed intakes of weanling piglets. A total of 25 pairs of Duroc$\times$Landrace$\times$Large White piglets weaned at 21 days of age were used in this experiment which finished on day 36. Each pair of healthy piglets from the same litter with similar body weight and of the same gender were selected and randomly arranged to ghrelin or control groups. Thus, there were 50 piglets (ghrelin 25; control 25) kept in 10 pens (ghrelin 5; control 5) and 5 piglets per pen. Initial body weight of the pigs did not differ between the control and ghrelin treatment ($7.43{\pm}0.17kg$; p = 0.81). Experimental pigs were infused with ghrelin ($1{\mu}g/d$ pig) via the marginal ear vein between 0750 and 0800 h at 22, 23, 24 days of age. Control pigs were infused with 0.9% saline. Feed consumption was measured on days 23, 24, 25, 29 and 36. Body weight was measured on days 22, 23, 24, 25, 29 and 36. Behavior data of individual piglets were collected by real-time observation from 0800-1500 h through remote supervisory equipment at 22, 23 and 24 days of age. The results indicated that ghrelin infusion could increase drinking (p<0.05) and lying behaviors (p<0.01) and decrease mounting behaviors (p<0.05). No significant influence of ghrelin was found on average daily weight gain (ADG) and average daily feed intake (ADFI) in this experiment (p>0.05). In conclusion, exogenous ghrelin by the method above and at the dosage of $1{\mu}g/d$ pig could cause a variety of behavioral effects, but not improve performance of weanling piglets.

  • Background: This study was carried out to investigate the interaction of p53 codon 72 polymorphism, dietary and tobacco habits with reference to risk of stomach cancer in Mizoram, India. A total of 105 histologically confirmed stomach cancer cases and 210 age, sex and ethnicity matched healthy population controls were included in this study. Materials and Methods: The p53 codon 72 polymorphism was detected by PCR-RFLP and sequencing. H. pylori infection status was determined by ELISA. Information on various dietary and tobacco related habits was recorded with a standard questionnaire. Results: This study revealed that overall, the Pro/Pro genotype was significantly associated with a higher risk of stomach cancer (OR, 2.54; 95%CI, 1.01-6.40) as compared to the Arg/Arg genotype. In gender stratified analysis, the Pro/Pro genotype showed higher risk (OR, 7.50; 95%CI, 1.20-47.0) than the Arg/Arg genotype among females. Similarly, the Pro/Pro genotype demonstrated higher risk of stomach cancer (OR, 6.30; 95%CI, 1.41-28.2) among older people (>60 years). However, no such associations were observed in males and in individuals <60 years of age. Smoke dried fish and preserved meat (smoke dried/sun dried) consumers were at increased risk of stomach cancer (OR, 4.85; 95%CI, 1.91-12.3 and OR, 4.22; 95%CI, 1.46-12.2 respectively) as compared to non-consumers. Significant gene-environment interactions exist in terms of p53 codon 72 polymorphism and stomach cancer in Mizoram. Tobacco smokers with Pro/Pro and Arg/Pro genotypes were at higher risk of stomach cancer (OR, 16.2; 95%CI, 1.72-153.4 and OR, 9.45; 95%CI, 1.09-81.7 respectively) than the non-smokers Arg/Arg genotype carriers. The combination of tuibur user and Arg/Pro genotype also demonstrated an elevated risk association (OR, 4.76; 95%CI, 1.40-16.21). Conclusions: In conclusion, this study revealed that p53 codon 72 polymorphism and dietary and tobacco habit interactions influence stomach cancer development in Mizoram, India.

  • Bed rest is recommended to prevent postlumbar puncture headaches(PLPHA), but the period of bed rest varies in the literature from 6 hours to 24 hours. In clinical practice the period of bed rest varies but nursing methods for adults and children have little difference. In Seoul National University Hospital, children have been given at least 6 hours bed rest after a lumbar puncture. Pediatric oncology patients require a lumbar puncture for an initial diagnosis, follow up treatment or administration of chemotherapeutic agent. But it is difficult for young children to lie supine or to refrain from their usual activities in any way, and unpleasant problems related to a shortage of beds often occurs during discharge or in an outpatient setting. The purpose of this study is to substantiate the preventive effect of PLPHA by the period of bed rest, to identify the other factors that influence PLPHA, and to use the nursing methods proper to children. The subjects were 65 children, ages 1-17, undergoing treatment in the children's cancer center at SNUCH during the period June 1, 1995, to Aug. 31, 1995. The team nurses asked questions about PLPHA of the parents and children in order to fill out a questionnaire. The data were evaluated by percent, t-test, Chi-square test and Mann-Whitney U test. Result; 1. There was no significant difference relating the bed rest time spent to the occurrence of postspinal headaches (t-test). 2. There was a significant risk of PLPHA in the children who were irritable before procedure and/or had experienced previous PLPHA(p<0.05, ${x^2}-test$). 3. The following factors were not found to be associated with increased risk of PLPHA: previous puncture experience, giving analgesics, the choice of puncturist, inpatient/outpatient status, gauge of needle, purpose, the amount of CSF removed, gender, diagnosis, the number of peripheral WBCs, previous lumbago experience after LP, position after bed rest, age, the number of aural puncture at the time. A longer period of bed rest is unlikely to be more effective to prevent PLPHA and seems impractical. A shorter period will save time and effort. Perhaps it will also allay some of the fears which surround LP. So 1 hour bed rest after LP is suggested and nursing methods for emotional support should be investigated to reduce PLPH.

  • This study was a descriptive research in search of a nursing intervention scheme to improve stroke patients' quality of life by understanding the relationship of stroke patients' ADL, depression, self-efficacy and quality of life with various variables and identifying factors that affect their quality of life. Each subject was interviewed one to one based on a structured questionnaire. With regard to research tools, Modified Barthel Index (MBI: Fortinsky et al., 1981), which was translated by Choi, Hye-sook (1996), was used in measuring ADL, Randloff's (1977) tool, which was translated by Choi, Soon-hee, was used in measuring depression, and the tool developed by Sherer et al. (1982), which is to measures self-efficacy under general conditions not limited to specific conditions, and modified by O, Bok-ja (1994) was used in measuring self-efficacy. The quality of life was measured using the scale of satisfaction of life developed by Diener et al. (1985). The results of this study were as follows: 1. The means of ADL of the subjects was $79.5{\pm}31.9$, depression $26.8{\pm}10.4$, self-efficacy $47.1{\pm}25.7$, and the quality of life $12.3{\pm}4.9$. 2. The subjects' quality of life showed a statistically significant difference according to gender (t=7.9, p= .006), satisfaction with income (F=5.8, p= .004), the burden of medical fee (F=3.7, p= .028) and the period of disease (F=2.8, p= .042). 3. With regard to relationship among ADL, depression, self-efficacy and the quality of life, ADL was in a relatively low positive correlation (r= .293, p= .003) with and the quality of life, depression in a high negative correlation (r=- .634, p= .000) with the quality of life, and self-efficacy in a positive correlation with the quality of life (r= .388, p= .000). 4. Factors that made a significant influence on the quality of life were depression (B=- .309, p= .001) and satisfaction with income (B=-2.611, p= .001). Based on these results, this study made following suggestions: 1. It is necessary to run rehabilitation programs to improve stroke patients' ADL, depression and self-efficacy. 2. It is necessary to perform research of monitoring stroke patients' quality of life in various areas using measuring tools.

  • The purpose of this study was to examine the relationship of the general characteristics of dental patients to their total O'Leary index and individual plaque indexes in a bid to check the oral hygiene state of citizens and evaluate their plaque management ability. The subjects in this study were 288 patients at dental hospitals and clinics in Busan and South Gyeongsang Province. A survey was conducted from September to November 2008. The findings of the study were as follows: 1. Overall, the O'Leary index of the patients investigated stood at 72 percent. By age and gender, the O'Leary index was highest among those in their 30s(83%) and among the women(75%)(p<.05). As to the influence of toothbrushing frequency, the patients who did it twice or more a day had the highest O'Leary index(75%)(p<.001). By the use of oral hygiene supplies, the patients who used oral hygiene supplies had a higher O'Leary index(76%) than the others who didn't(p<.01). 2. As for plaque index for each tooth, 28 percent of their teeth were given zero point, and 52 percent were given one mark. 13 percent were given two marks, and 6.3 percent were given three marks. Thus, the teeth that were given one mark were largest in number(p<.001). 3. As for plaque index for labial posterior mandibular, 43 percent of their teeth were given one point, and 36 percent were given zero mark. 14 percent were given three mark, and 5 percent were given three marks(p<.01). 4. As for plaque index for buccal posterior maxilla, 57 percent of their teeth were given one point, and 20 percent were given zero mark. 16 percent were given two mark, and 6.3 percent were given three marks(p<.01). 5. As for plaque index for lingual posterior mandibular, 56 percent of their teeth were given one point, and 27.8 percent were given zero mark. 9 percent were given three mark and 6 percent were given three mark(p<.001).
