The study was conducted to find out the concentrations of sex hormones and the contents of metabolites in serum, and the changes of weights and tissues on ovary, thyroid gland and adrenal gland according to gestation period in rabbit. The results were summarized as follows: 1. The ovary weights were increased significantly with the time e lapse after gestation and recovered normally at 5 days after parturition. In the histological changes of ovary, the lutein cells were hypertrophied and the secretory granules were increased actively until 3 weeks after gestation, and then a trophied thereafter. 2. The thyroid gland weights at all observation times were higher than those in control group, and the significance was recognized at 1, 3 and 4 weeks after gestation. The histological features of the secretory epithelium were the hyper trophic and columnar condition stimulating the functional state from 1 week after gestation. 3. The adrenal gland weights in experimental group were recognized significantly at 4 weeks after gestation, but showed higher than those in control group at all observation times. The zona fasciculata and zona reticularis of the gland showed the slight hypertrophic condition, but the zona glomeerulosa and adrenal medulla did not find out any particular changes. 4. The serum concentrations of progesterone and LH reached a peak level at 2 weeks and 1 week after geestation respectively, and rapidly began to decline thereafter. 5. The serum concentrations of estradiol-$17{\beta}$ and FSH were not detected below 20.0 pg/ml and 1.3 mIU/ml respectively. 6. The contents of total protein and non-protein nitrogen nitrogen were decreased gradually with the time elapse after gestation, but the significant differences were recognized from 3 weeks. 7. The total lipids were not changed markedly until 3 weeks, but increased significantly at 4 weeks after gestation and at 5 days after parturition. 8. The serum cholesterol tended to be decreased until 3 weeks, but increased at 4 weeks after gestation and at 5 days after parturition. 9. The serum calcium showed a continuous decrease during the gestation period, but the significant differences were recognized at 3 and 4 weeks. The serum phosphorus also had a significant decrease at 4 weeks after gestation.

Objectives：For the purpose of obtaining the more vivid present status and prevention program of teenage pregnancy, this survey was done by Obstetricians, as study subject, who manage the pregnant teenager in real clinical situation. Methods：Structured survey form about teenage pregnancy was sent to 2,800 obstetricians. That form contained frequency, characteristics, decision making processes, and psychiatric aspects of the teenage pregnancy. 349 obstetricians replied that survey form and we analysed these datas. Results：(1) The trend of teenage pregnancy was mildly increased. (2) The most common cases were unwanted pregnancy by continuing sexual relationship with boyfriends rather than by forced, accidental sexual relationship with multiple partners. (3) The most common reason of labor was loss the time of artificial abotion. (4) Problems of pregnant girls' were conduct behaviors and poor informations about contraception rather than sexual abuse or mental retardation. (5) Most obstetricians percepted the necessity of psychiatric consultation, however psychiatric consultation was rare due to parents refusal and abscense of available psychiatric facility. (6) For the prevention of teenage pregnancy, the most important thing was practical education about contraception. Conclusions：Based on the result of this study, further study using structured interview schedule with pregnant girl is needed for the detecting risk factor of teenage pregnancy and effective systematic approach to pregnant girl.

The purpose of this study was to investigate the risk factors of pregnancy and the relationship between pregnancy experience and suicidal behavior in 284 pregnancy experienced adolescents aged 13-19 years. The suicidal ideation was 57.8%, the suicide plan was 37.7% and the suicide attempt was 37.3% among female adolescents with pregnancy experience. By multivariate logistic regression analysis, female adolescents who experienced pregnancy had 1.44 times more suicidal ideation, 2.39 times more suicide plans, and 2.38 times more suicide attempts than those without suicidal thoughts, plans and attempts. Because of the high correlation between pregnancy experience and suicidal behavior in female adolescents, school and education authorities need systematic education and countermeasures to prevent adolescents' pregnancy and risk of suicide after pregnancy. And above all, convergent support and interest in home, school and community comprehensive area should be supported.

The causes of aortic dissection are usually hypertension, connective tissue disease such as Marfan syndrome, congenital valvular abnormality such as bicuspid aortic valve, iatrogenic injury, pregnancy and drugs. Previous studies have shown that 50% of all dissections in women less than 40 years age were associated with pregnancy. Almost all aortic dissections during pregnancy occur during the third trimester or during labor and delivery. Marfan's syndrome is a particularly important predisposing factor for aortic dissection during pregnancy. We report here on a case of surgical treatment for acute type II aortic dissection in a Marfan syndrome patient who was 24 weeks pregnant, and we include a review of literature.

This study was performed to compare the status of oral care knowledge, oral care practice, and the patterns of the oral health care utilization before and during the pregnancy. It was conducted on the basis of a survey of 291 pregnant women who were in 9 post-natal care centers for post-natal care after delivery located in Daegu Metropolitan city and Changwon city of Gyeongsangnam-do from April 1st till April 29th on 2010. Forty five percent of them were experienced with the gum bleeding before pregnancy and 55.7% were experienced during pregnancy. The number of average tooth brushing per day was 3.05 times before pregnancy and 2.99 times during pregnancy in the survey. The patients who were experienced in dental health care during pregnancy out of the subjects for study were 51 for 17.5%. The score for the dental health knowledge was 7.82 for 10 grade scale and 5.38 before pregnancy and 5.14 during pregnancy for 10 grade scale in the actual performance scoring for dental care. Pre-dental care, experience in activity restriction due to dental disease, concern about oral health and regular visit to dental clinic were significant associated with use of dental care services during pregnancy.

A male infant was diagnosed with obstetric brachial plexus injury, congenital muscular torticollis and cleft palate 17 days after birth. His mother presented with gestational diabetes and premature rupture of membranes. Although it is possible that these three disorders arose independently, it is very likely that all three have the same etiologic cause, and we propose that a possible mechanism for this concurrence is related to maternal gestational diabetes. Maternal hyperglycemia mostly affects fetal structures deriving from the neural crest, including the palatine bone, and may have caused the cleft palate observed in this case. Gestational diabetes is also associated with increased frequency of large for gestational age infants and, by extension, with increased risk of birth injuries such as obstetric brachial plexus injury or congenital muscular torticollis associated with large for gestational age infants. Since the children of mothers with gestational diabetes are at increased risk for congenital defects such as cleft palate as well as being large for gestational age, precautions indicated for each respective disorder must be taken during prenatal testing and during birth. However, further studies of more cases are required to evaluate whether the concurrence of obstetric brachial plexus injury, congenital muscular torticollis and cleft palate in this case are complications specifically associated with gestational diabetes or just a simple coincidence.

보수적인 대한민국의 사회에서 성은 향상 음지에서 활동하는 영역이었다. 대부분의 사람들이 성생활이 삶에서 중요한 부분이라는 것을 인정하지만, 그에 대해 자세히 알기는 부끄러워한다. 특히 여성 당뇨병환자는 성 기능 장애와 임신성 당뇨 등 많은 위험이 존재함에도 성이라는 이름으로 교육과 치료를 미루고 있어 안타까운 실정이다.

한우의 번식에 있어서 번식효율을 증진하기 위해서는 정확한 수정적기의 선택과 수정 후 가능하면 조기에 임신감정을 실시하여 공태기간을 최소로 단축시켜 번식우의 효율을 증진하고 송아지 생산비를 줄여야 할 것이다. 임신감정은 일반적으로 인공수정사나 수의사가 직장검사를 통해 태아를 확인하는 방법이 있으나, 이 방법은 수정 후 50-60일 이후부터 가능하며 숙련자에 따라 진단율이 다르며 암소에게 스트레스를 주고 태아나 난소에 손상을 주거나 심하면 태아의 조기폐사 등의 부작용이 있으며 진단율도 2-3만원 정도 소요된다. 최근 임신진단을 현장에서 간단히 조기에 진단할 수 있는 새로운 방법이 개발되어 있어 소개하기로 한다.
