Objectives : These experiments were undertaken to evaluate the effect of the administration on Korean herbal medicines, Kyoaekungkue-tang, Bojungykki-tang, Kungso-san, Antae-eum, and Antaegumchul-tang, on the reproductive functions in pregnant mice. Methods : Prepared herbal medicines(Kyoaekungkue-tang, Bojungykki-tang, Kungso-san, Antae-eum, Antaegumchul-tang) were administered to three different pregnant staged mice. We designed 3 experiments as follows; prepared herbal medicine administered from ovulation to embryo implantation (Experiment I), or administered after implantation to fetal organogenesis (Experiment II) and lastly administered from end of organogenesis to parturition (Experiment III). At day 14 of pregnancy, the whole uteri of half of the treated mice were retrieved from the Experiment I and in the Experiment II the implantation and mean weight of the fetuses were examined. The mean numbers of offspring, sex ratio and mean birth weight were examined in the other half of the mice. Results : The results from these studies were summarized as followed; 1. From the experiment I (administered from ovulation to embryo implantation), the no. of implantation between control and herbal medicine treated groups were shown similar results. Litter size after parturition was significantly decreased in the herbal medicine treated groups, except for Antaegumchul-tang. However, the mean weight of offspring after parturition showed a tendency to increase in the three herbal medicine treated groups. 2. From the experiment II (administered after implantation to fetal organogenesis), the implantation rates from the herbal medicine treated groups increased more significantly than that of the control Also, litter size and birth weight in the herbal medicine groups, except Antaeeum, increased more significantly than that of the control group. 3. From the experiment III group (administered after organogenesis to parturition), the mean number of offspring in Kyoaekungkue-tang and Antaegumchul-tang treated groups were significantly increased than that of control However, the litter size of the Kungso-san treated mice was significantly decreased compared with that of the control group. Compared with the control and other herbal treated groups, the mean weight of fetuses after parturition in the Kyoaekungkue-tang and Antaegumchul-tang treated groups increased significantly. Conclusions : From these results, it can be concluded that Antaegumchul-tang showed more beneficial effects on the reproductive functions, implantation, maintenance of pregnancy, litter size and mean weight than other herbs.

체색의 변화가 다양하여 관상용으로 가치가 높은 Hippocampus coronatus의 안정적인 번식기술을 개발하기 위하여 가막만과 여자만 부근해역의 잘피밭에서 채집 한 후 실험실에서 사육하면서 어미의 출산특성, 자치어의 성장 및 초기자어사육에 알맞은 먹이조건을 조사하었다. $7{\sim}11$월에 가막만과 여자만에서 출현한 체장(SL) $53.91{\sim}87.31 mm$ (평균 $77.76{\pm}9.84 mm$, n=12) 범위의 개체들이 실험실내에서 $6{\sim}75$ 개체(평균 39 ind./male/time)를 출산하였다. 출산 직후 자어의 크기는 $11.69{\sim}15.81 mm$(평균 $13.7{\pm}1.3 mm$, n=15)였고 몸통과 꼬리의 체륜수는 10 그리고 39개였으며 가슴지느러미, 등지느러미 그리고 뒷지느러미 줄기수는 각각 12, 14 그리고 4개였다. 출산 후 60일에는 $23.48{\sim}25.29 mm$ (평균, $24.65{\pm}0.83 mm$, n=4)로 성장하였고 일간성장률은 0.18 mm/day였다. Copepod와 Artemia를 혼합 공급하여 포식량을 조사한 결과 출산 후 5일째에 copepod nauplii의 포식량은 평균 21 ind./larva/hour였고 Artemia napulii의 포식량은 평균 3 ind./larva/hour로 copepod nauplii에 대한 선호도가 높았고 출산 후 30일째에는 copepod nauplii에 대한 포식량이 평균 5 ind./larva/hour, 그리고 Artemia napulii의 포식량이 평균 9 ind./larva/hour로 성장함에 따라 Artemia napulii에 대한 포식량이 증가하였다. 생존율을 고려한 먹이 공급방법에 있어서 Artemia nauplii와 copepod nauplii를 혼합 공급할 경우 생존율은 출산 후 50일에 48.9%로 향상된 결과를 얻을 수 있었다.

광주기와 수온의 인위제어에 따른 조피볼락, S. schlegeli의 교미 및 출산 조절을 번식생물학적으로 조사하였다. 어미의 출산유도 사육실험은 자연조건의 대조구와 광.수온 조절의 실험구로 나누어 사육하였다. 실험구에 있어서 광주기 조절은 교미시기에 9L:15D, 출산시기에는 14L:10D로 조절하였다. 수온 조절은 교미시기 12~13$^{\circ}C$, 출산시기에 14~15$^{\circ}C$로 조절하였다. 수컷의 GSI는 1996년 4월에서 8월까지 딱 0.12로 낮은 값을 유지하였고, 대조구는 11월에 1.36$\pm$0.10, 실험구에서는 10월에 1.27$\pm$0.05로 각각 최대값에 달하였다. 암컷의 GSI는 1996년 1월에서 11월까지 약 1.82로 낮은 값을 유지하였고, 대로구는 4월에 46.5$\pm$5.72, 실험구는 1997년 2월에 42.0$\pm$4.24로 각각 최대값을 가졌다. 광주기와 수온을 조절한 실험구는 정소와 난소의발달 양상이 대조구와 유사하였으나, 교미와 출산은 2~3개월 앞당길 수 있었다.

본 연구는 체세포 복제란 이식우의 분만에 있어서 혈중 스테로이드호르몬, TGF-${\beta}_1$ 농도와 분만지연의 상관 관계를 살펴보고자 실시하였다. 대조군으로는 인공수정(AI)을 통하여 임신한 암소(cow)들을 사용하였다(AI-R). 모든 AI-R들은 자연분만(n=5, 임신 $284{\pm}0.71$일)을 하였다. 분만징후를 보이지 않는 체세포 복제란 이식우(n=5, SCNT-R)들은 분만 예정일보다 10일 정도 지난 임신 292일째에 제왕절개(Caesarean section, C-sec)를 실시하여 분만하였다. 혈액 및 태반 샘플을 분만 전.후에 채취하여 형태 및 중량 등을 측정하였다. 혈장호르몬인 Progesterone(P4)와 Estradiol-$17{\beta}$(E2) 농도는 방사선동위원소 면역 분석 시험(RIA) 방법을 이용하여 측정하였다. 혈장 및 태반분엽의 TGF-${\beta}_1$ 농도는 ELISA 방법으로 측정하였다. SCNT-R에서 회수한 태반의 무게는 AI-R의 것과 비교하여 유의적으로 무거웠다(p<0.05). 분만 직전 SCNT-R들의 혈장 내 P4 농도는 AI-R들의 그것과 비교하여 유의하게 높았다(p<0.01). 하지만 SCNT-R들의 혈장 내 E2 농도는 AI-R과 비교하여 상대적으로 낮게 나타났다(p<0.01). 한편, 분만 전.후 SCNT-R들에서 혈장 또는 태반분엽의 TGF-${\beta}_1$ 단백질 발현 수준은 AI-R들과 비교하여 각각 유의적으로 높은 수준을 유지하였다(p<0.01). 이상의 결과를 종합하여 보면, 분만 시 P4 및 E2의 이상 발현과 높은 수준의 혈장 및 태반 내 TGF-${\beta}_1$ 단백질은 체세포 복제태아의 분만지연을 야기하는 중요한 요인들 중의 하나일 것이라 사료된다.

Postpartum depression is a kind of serious problem which influences on the postpartum woman, her family and infant. It has been known to be caused by many factors and some depression scales have been used to assess the degree of postpartum depression. Edinburgh postnatal depression scale(EPDS) is simple and efficient method. Because of the difficulty of diagnosis and valuation on the postpartum depression, there has been a few case report on oriental medical treatment. I report one postpartum depression case which was valuated by EPDS and had objective evidence. In this case herbal treatment and acupuncture was efficacious on the postpartum depression. I think, though six month has passed from parturition, there need to be treated after parturition weakness and deficiency point of view.

The variation in the diet of Rhinolophus ferrumequinum was investigated through analysis of feces collected before and after parturition. The results shows a high use of Coleoptera, which accounted for 30-77% in diet. Diptera(total 27.38%), and Lepidoptera(total 13.31%) was also consumed for the most part. Prey types recovered also included small numbers of Hymenoptera, Neuroptera. The diet of R. ferrumequinum varies before and after parturition. In lactating period, Coleoptera was mainly consumed(77%), but the use of Diptera significantly increased in post-lactating period.(51%)

The purpose of this study was to measure the serum content of progesterone, estradiol 17${\beta}$ and cortisol. Blood samples collected from day 20 prepartum to day 20 postpartum in 8 sows. Progesterone and estradiol-17${\beta}$ were assayed by radioimmunoassay methods and cortisol was determined by competitive protein-binding methods. Progesterone levels began to decline on day -4, reached 1.9ng/ml by day +2 and remained quite constant thereafter. Progesterone levels remained fairly constant(18.4 to 20.0 ng/ml) from 20 to 6 days before parturition. Estrdiol-17${\beta}$ increased from 205 pg/ml at day 6 prepartum to 425 pg/ml at the time of parturition. Cortisol reached a peak level of 86.5 ng/ml at day 0.

This study was conducted to investigate optimal time of artificial insemination (AI) to Hanwoo female after natural estrus. AI was occurred 12 and 24 hours after natural estrus in both heifer and multiparous recipient then pregnancy and parturition rates were estimated. Results indicated that AI performed at 24 hours after natural estrus showed significant (p<0.05) higher pregnancy rate in both heifer and multiparous recipient groups with significantly (p<0.05) higher abortion rate. However, there are no significant differences of parturition rate, twin birth and sex ratio in both heifer and multiparous recipient groups. Therefore, our results may suggest that performance of AI at 24 hours after natural estrus promise higher pregnancy rate than AI at 12 hours after natural estrus in both heifer and multiparous recipient.

A 2-year-old, intact female, mixed breed dog with depression, anorexia, poor mothering, and uterine prolapse was referred to the Haemaru Referral Animal Hospital. The prolapse(Y-shaped uterus) was detected on the fifth day of normal parturition(eight live pups). Depending on physical examination, bilateral uterine horns and uterine body were prolapsed into the vagina. The ovariohysterectomy was performed after the uterus with manual reduction through the vulva. In this case, uterine prolaspe was occurred in a primiparous bitch has been through normal parturition.
