Several studies have been done regarding carcass traits and growth in pigs. Recently, these have progressed to examine increases in economic traits, including meat quality and meat quantity, by using candidate genes. One of them is the pituitary-specific protein PIT-1, a member of the POU (Pit-Oct-Unc) family of transcription factors playing an important regulatory role in developmental processes. In addition, muscle development is known to be regulated in part by growth factors and cytokines locally produced. Therefore, studies were performed to analyze PIT-1 genotypes and serum cytokines (IGF-I, IGF-II, TGF-${\beta}1$, EGF, cortisol, DHEA-S, IL-2, and IL-6) in castrated male pigs for their possible involvement in the development of carcass traits. The genotypes of PIT-1 gene were analyzed by PCR-RFLP with MspI restriction enzyme. But, only CD and DD genotypes, not CC genotype, have been detected. Based on PIT-1 genotyping, a significant difference in EGF expression beween CD type (78.8 ng/ml) and DD type (46.0 ng/ml) was detected (p<0.05), whereas other cytokines did not show any statistical significance depending on PIT-1 genotypes. Collectively, these results suggest the possibility that EGF could affect the formation of carcass traits.

The Low Birth Weight infant birth rate in this country is a little more than 15 percent and is being increased. The survival rate of Low Birth Weight infant is over 90 percent and recently the rate runs is getting. However, because of the high risk of Low Birth Weight infant for handicap in growth, a preventive nursing intervention program for Low Birth Weight infant and their mother is considered to be necessary. Touch and massage, thus sensory stimulation has been considered to be important ensuring a normal growth of Low Birth Weight infant During the past decades sensory stimulation program has been used for premature and Low Birth Weight infants. Recently a study on the sensory stimulation for Low Birth Weight infants has bee n done in this country. Mother and infant relationship has a great influence on child's development. Especially, mother and infant interaction during one year after birth plays important role in child's social. affective and cognitive developments. But in the study of Low Birth Weight infants, the mother and infant interaction has been rare yet. However, there was no study effectiveness of the sensory stimulation on mother and infant interaction. In this respect, this study based on the importance of the nursing intervention, is intended to measure the effectiveness of the massage therapy in the aspects of weight, daily feeding amount, cortisolurine stress hormone and mother and infant interactions. This study has been conducted on the nonequivalent control group pretestposttest design in quasi experimental basis and Low Birth Weight infants from NICU of two Medical University Hospitals located in Taegu Metropolitan were selected in experimental group of 21 infants and control group of 20 infants. Data has been collected from May 1, 1999 to September 5, 2000. For the experimental group Field's sensory stimulation(tactile and kinesthetic stimulation) was applied 2 times a day for 10 days(10:00 - 11:00 hours in the morning and 19:00 - 20:00 in the afternoon) by nurse and mother. The electronic indicator scale (Cas Co. Korea) was used to measure infant's body weight. To determine urine cortisol concentration level under stress, rad immuno assay method was used. And to determine mother and infant interactions during feeding, tools developed by Kim Mi-Ye (1999) were used. Collected data were analyzed with SAS program using x-test, t-test, paired t-test and repeated measures ANOVA. Findings were as follows : 1. For the daily mean weight gain, the experimental group showed little higher than the control group, even though, there was no Statistically significant differences between two groups. 2. For the amount of daily mean feeding, the experimental group showed little higher than the control group, while there was no Statistically significant differences between two groups. 3. The level of wine cortisol concentration was increased in both groups, while no Statistical significance was shown between the two groups. 4. Mothers in experimental group were more likely to have higher mean scores in mother and infant interaction during feeding than mothers in the control group. Statistical significance was shown between the two groups(t= 5.78, P=.001). In conclusion, the massage therapy in this study showed with regard to even though through there was no statistically significance in the weight gain and urine stress hormone concentration. there was Statistical significantly higher in the mother and infant interaction during feeding. Based on the result of this study, it is considered that the massage therapy should be applied clinical practice and home to help a developmental growth and interaction of Low Birth Weight infants and mothers during the period of recovery.

Objective : We analyzed the clinical and endocrinological results of the transsphenoidal microsurgery for ACTH secreting pituitary adenomas. Marerials and Methods : From October 1995 to August 2000, 18 patients underwent transsphenoidal microsurgery for Cushing's disease. We analyzed the surgical results of 17 patients, one patient who was previously operated from other hospital was excluded. Age of the patients were 18 to 61 years old(mean 37.7), male to female ratio was 1 : 3.3, and follow-up period was 3 to 50 months(mean 20.3). The selection of candidates for transsphenoidal exploration was based on endocrinologic criteria. Magnetic resonance imaging was the preferred radiologic test. Selective inferior petrosal sinus sampling of adrenocorticotropic hormone futher refined the diagnosis when endocrinologic and radiologic procedures were not definitive. Results : Results of the preoperative endocrinological test were : level of serum ACTH 29.4 to $225{\mu}g/dL$(mean $93.88{\mu}g/dL$) ; serum cortisol 11.9 to $47.5{\mu}g/dL$(mean $27.49{\mu}g/dL$) ; 24-hour urine free cortisol 235 to $1019{\mu}g/day$(mean $571.0{\mu}g/day$). Inferior petrosal sinus sampling for ACTH was performed in 11 patients and all were confirmed by Cushing's disease and we could predict the laterality of the tumor in 9 of 11 patients. We performed transsphenoidal selective adenomectomy in 5 patients, adenomectomy and subtotal hypophysectomy in 2 patients, adenomectomy and partial hypophysectomy in 9 patients, and in the remaining one patient, hemihypophysectomy followed by total hypophysectomy due to remission failure. Fifteen of 17 patients(88.2%) showed endocrinological remission. Glucocorticoid replacement therapy was performed in all the patients who showed remission for 1 to 24 months(mean 5.9 months), and 6 patients received steroid over 6 months. Conclusion : We conclude that the direct demonstration of a tumor in the pituitary gland by MRI is the most important and definitive diagnostic tool and the location of a mass should be confirmed with increased level of ACTH by the inferior petrosal sinus sampling. Transsphenoidal microsurgery is effective treatment modality for Cushing's disease and the immediate postoperative evaluation of the surgical resection of the tumor is very important. The patients should show hypocortisolism, decreased, subnormal serum ACTH and cortisol levels and 24-hours urine free cortisol. We performed 18 transsphenoidal microsurgery for Cushing's disease in 17 patients and 15 patients(88.2%) showed endocrinological remission.

본 연구는 흰쥐(S.D, ♂)에 각 처리에 따라 기초사료로 시판사료(T$_1$)를 무제한 급여하면서 시험사료로 한약 증탕액 (T$_2$), 오골계 증탕액(T$_3$), 오골계 교잡종 육에 Flavourzyme을 0.1%첨가하여 가수 분해시킨 후 한약제와 혼합하여 증탕시킨 증탕액(T$_4$)을 35일간 경구 투여한 후 흰쥐의 혈청에 대한 glucose및 hormones과 면역학적 변화에 미치는 영향을 조사 한 결과는 다음과 같았다. 비만하였을 때나 과도한 스트레스를 받았을 때 insulin 함량이 증가한다고 하였으나 효소 처리 오골계 교잡종 증탕액을 급여한 처리구에서 체중 증가가 일반사료를 급여한 처리구에 비해 유의적으로(p<0.05) 증가하였어도 insulin 함량이 일반사료 급여구보다 증가하지 않은 것으로 나타나 바람직한 생리현상을 나타냈다. Aldosterone은 스테로이드 계통의 호르몬으로 물의 생리적 밸런스와 혈압조절에 관여하는데 일반사료 급여구에 비해 한약 증탕액, 오골계 증탕액,효소 처리 오골계 증탕액 급여 구에서 낮은 함량을 나타내 고농도 단백 식이의 급여에도 불구하고 aldosterone수치의 저하로 혈압 저하의 효과를 나타 낸 것은 한약을 첨가시켜 고압으로 처리시킨 증탕액의 효과와 가수분해 효소에 의한 소화가 용이하도록 처리한 결과로 사료된다 Cortisol은 스트레스 측정에 감도가 높은 호르몬으로 알려져 있는데 일반사료급여구가 0.67 nmol/L인 반면 증탕액을 급여한 구에서는 0.40∼0.49 nmol/L으로 cortisol 농도가 감소하는 경향을 나타냈는데 이는 aldosterone에서와 같이 한약제와 동물성 단백질을 섭취함에 따른 효과로 사료된다. 흰쥐에 증탕액 급여가 면역반응에 미치는 영향에서 IL-4, IFN-v 및 anti-BSA IgG의 역가는 일반사료를 급여한 처리구에 비해 오골계 증탕액 및 효소 처리 오골계 교잡종 증탕액 급여구에서 spleen과 serum두에서 증가하는 경향을 나타내었는데 앞에서 언급했던 바와 같이 한약(십전대보탕)의 효과와 소화시키기 쉬운 고농도의 단백질 가수분해 물질의 다량 섭취에 의해 면역 활성이 증가되었을 것으로 사료된다.

Objective: To investigate psychological distress and fertility quality of life (FertiQoL) in infertile Korean women, and to investigate whether a correlation exists between psychological distress and FertiQoL. Methods: Participants in this study were made up of 141 infertile women and 65 fertile women. We conducted a survey on psychological distress (using the Depression Anxiety Stress Scales [DASS]-42 questionnaire) and administered a FertiQoL questionnaire. The levels of stress hormones (adrenocorticotropic hormone [ACTH] and cortisol) in serum were assessed. Results: The scores for depression ($13.7{\pm}8.4$), anxiety ($10.7{\pm}6.4$), and stress ($18.0{\pm}8.3$) among the infertile women were significantly higher than the scores for depression ($9.4{\pm}7.5$), anxiety ($6.6{\pm}6.0$), and stress ($12.2{\pm}8.3$, p<0.001) among the fertile women. There was no difference in the scores for depression ($13.5{\pm}8.2$, $13.8{\pm}8.6$), anxiety ($10.0{\pm}6.2$, $11.5{\pm}6.6$) and stress ($17.7{\pm}8.4$, $18.4{\pm}8.1$) between younger (${\leq}34$) and older (${\geq}35$) participants. The mind-body (r =-0.495) and emotional (r =-0.590) subscales showed a higher negative correlation with stress compared with other scales of psychological distress. At the same time, the social (r =-0.537) and relational (r =-0.385) subscales showed a higher negative correlation with depression. Levels of cortisol and ACTH in infertile women were $9.1{\mu}g/mL$ and 11.9 pg/mL, respectively, which are within normal ranges. Conclusion: The levels of psychological distress and quality of life in infertile Korean women seem to require psychological intervention. This study provides a baseline measurement of psychological distress and FertiQoL in infertile women in Korea, which will be available for developing psychological interventions for infertile Korean women.

Objectives Aromatase inhibitors that block estrogen synthesis are a proven first-line hormonal therapy for postmenopausal breast cancer. Although it is known that standardized extract of Ginkgo biloba (EGb761) induces anti-carcinogenic effects like the aromatase inhibitors, the effects of EGb761 on steroidogenesis have not been studied yet. Therefore, the effects of EGb761 on steroidogenesis and aromatase activity was studied using a H295R cell model, which was a good in vitro model to predict effects on human adrenal steroidogenesis. Methods Cortisol, aldosterone, testosterone, and $17{\beta}$-estradiol were evaluated in the H295R cells by competitive enzyme-linked immunospecific assay after exposure to EGb761. Real-time polymerase chain reaction were performed to evaluate effects on critical genes in steroid hormone production, specifically cytochrome P450 (CYP11/ 17/19/21) and the hydroxysteroid dehydrogenases ($3{\beta}$-HSD2 and $17{\beta}$-HSD1/4). Finally, aromatase activities were measured with a tritiated water-release assay and by western blotting analysis. Results H295R cells exposed to EGb761 (10 and $100{\mu}g/mL$) showed a significant decrease in $17{\beta}$-estradiol and testosterone, but no change in aldosterone or cortisol. Genes (CYP19 and $17{\beta}$-HSD1) related to the estrogen steroidogenesis were significantly decreased by EGb761. EGb761 treatment of H295R cells resulted in a significant decrease of aromatase activity as measured by the direct and indirect assays. The coding sequence/Exon PII of CYP19 gene transcript and protein level of CYP19 were significantly decreased by EGb761. Conclusions These results suggest that EGb761 could regulate steroidogenesis-related genes such as CYP19 and $17{\beta}$-HSD1, and lead to a decrease in $17{\beta}$-estradiol and testosterone. The present study provides good information on potential therapeutic effects of EGb761 on estrogen dependent breast cancer.

건강과 삶의 질 향상에 대한 관심이 커짐에 따라 도시녹지가 가져다 주는 건강편익이 크게 주목되고 있지만, 이에 관한 객관적이고 과학적인 데이터는 매우 부족한 실정이다. 따라서 본 연구에서는 도시녹지가 가져다 주는 건강편익에 대한 과학적 자료를 얻기 위해 생리적, 심리적 지표를 활용하여 실험을 실시하였다. 과거병력이 없는 20대 남자 대학생 20명이 실험에 참가하였고, 자극은 녹지와 도시에서 실제의 경관을 15분간 감상하는 것으로 하였다. 이번 연구는 충남대학교 의학전문대학원 생명윤리심사위원회의 승인을 받은 후 실시되었다. 녹지와 도시에 대한 생리반응을 분석한 결과, 도시에 비해 녹지에서 심박동수가 현저히 감소하였고, 안정상태에서 증가하는 부교감신경활동이 유의하게 향상되었으며, 스트레스호르몬의 일종인 코티솔 농도가 낮아지는 경향이 보였다. 심리반응에 있어서는 부정적인 감정과 정신상태가 녹지에서 보다 유의하게 낮아진 반면, 활력은 유의하게 증가하였다. 이번 연구의 결과는, 녹지를 접하는 것이 심리적 변화뿐만 아니라 인체의 자율신경계와 내분비계 활동에 긍정적 변화를 가져다 준다는 것을 보여주는 것으로써, 녹지가 도시민의 건강증진과 관련하여 매우 직접적인 환경요인이 될 수 있음을 과학적으로 뒷받침한다고 할 수 있다.
