Jugular plasma concentrations of luteinizing hormone, prolactin, estradiol-17\ulcorner and 13, 14-dihydro-15-keto-prostaglandin-F2봬(PGFM) were meausred prepartum during the last 12 days of pregnancy, at parturition, then 1 day after parturition in 16 goats. Plasma samples were analyzed for luteinizing hormone(LH), estradiol-17\ulcorner(E2), prolactin(PRL) and prostagladin F2봬(PGF2봬) concentrations by radioimmunoassay. 1. The concentrations of plasma luteinizing hormone in Korean native goats remained fairly constant(0.20 0.02\ulcorner0.38 0.04 mlu/ml) from 12 days prepartum to 1 postpartum but the concentrations of plasma prolactin rose slightly from 1 day prepartum. 2. The estradiol-17\ulcorner concentrations increased rapidly after day 1 before partum, reaching a peak at parturition(74.8 77.5 pg/ml), and falling to 63.8 2.8 pg/ml at day 1 postpartum. 3. Starting at 323.2 69.6 twelve days before parturition, the concentrations of plasma prostaglandin F2봬 rose during the 1 day preceeding parturition(650.7봬57.8 pg/ml) and peaked at 1081.4 164.9 on the day of parturition. At day 1 postpartum, the concentrations of PGF2봬 decreased to 425.3 60.4 pg/ml. Finally, these results show that changes in prostaglandin F2봬 concentrations before parturition were closely related to changes in estradiol-17\ulcorner concnetrations, but after parturition they remained elevated whereas estradiol-17\ulcorner concentrations fell abruptly.

From May, 1979 to October,1987, 38 patients with endometrial carcinoma were treated with radiotherapy at Seoul National University Hospital. Of these, 32 patients received radiotherapy Postoperatively, one received radiotherapy preoperatively, and five received radiotherapy only. Relative frequencies of obesity, nulliparity, late menopause, diabetes mellitus, and hypertension were all higher than those reported in normal women in Korea, and those of obesity, diabetes mellitus, and nulliparity were significantly high. The overall actuarial five-year survival rate was $75.6\%$. The overall actuarial five year survival rates of stage I (22 cases), stage II (six cases), and stage III (10 cases) were $90.0\%,\;80.0\%,\;and\;44.4\%$, respectively, and were significantly different from each other. Among various factors, stage only proved to be prognostic by multivariate analysis. There were two local failures, three local failures combined with distant metastasis, and three distant metastasis. Stages I and II could be adequately controlled by local modalities without severe complications, stage III endometrial carcinoma might need more aggressive treatment for better survival.

This study was conducted to compare the aspects of behavior between miniature pigs and conventional sows during gestation and lactation periods. Miniature pigs and conventional sows at 3 parity were used in this experiment with 4 pigs per treatment. The behavioral patterns and stereotyped behaviors were observed on day 60 and 90 of gestation, at farrowing, and on day 10 of lactation before and after the feeding. On 60 and 90 days of pregnancy, both treatments showed the tendency of frequent lateral lying rather than other postures. On ventral lying, eating and drinking, miniature pigs spent more time than conventional pigs at day 90 of gestation (P<0.01, P=0.0539, P<0.05, respectively). The occurrence of stereotyped behaviors included bar biting and bar mouth chewing. At 90 day of pregnancy was observed, conventional pigs was higher than miniature pigs (P<0.05). At farrowing, miniature pigs spent more time on ventral lying, standing and walking than conventional sows (P<0.05), however, there were more frequency of drinking and eating. And on day 10 of lactation, there was no significant difference in stereotyped behaviors between miniature pigs and conventional sows. In conclusion, miniature pigs were generally more sensitive than conventional sows although sows were reared in stall during gestation and lactation period and the behavioral pattern during lactating period showed the similarity between miniature pigs and conventional sows for protection of nursing pigs. In consideration of the general reproductive performance of conventional sows, the high sensitivity and stress of miniature pigs did not affect the reproductive performance of miniature pigs.

체세포 핵이식에 의한 복제기술은 매우 낮은 성공률 나타내고 있어 실용화에 지장을 초래하고 있다. 이것은 후생적인 유전현상인 reprogramming이 불완전하게 이루어지기 때문인 것으로 추측되어지고 있다(Reik et al., Theriogenology 2003, 59: 21-32; Han et al, Theriogenology 2003, 59: 33-44). 체세포 핵이식 후에 태아사망의 원인이 태반의 비정상적인 기능과 관계가 있는 것으로 추정되는데 복제시 태아사망의 원인을 찾기 위해 본 연구를 시행하였다. 한우에서 체세포 복제 후 임신 말기에 태아가 사망한 태반조직 3개와 IVF 수정란 이식 후 동일한 시기에 제왕절개술을 실시한 태반조직 2개를 실험에 이용하였다. 태반 protein을 Two-Dimensional electrophoresis와 Mass spectrometer를 이용하여 분석 비교하였다. IPG-system을 이용하여 pH 4~7, pH 6~9에서 1차 전기영동을 한 후, 8~l6%의 SDS-PAGE gel에 2차 전기영동을 실시하였고 G-250 Coomassie로 염색하였다. gel 이미지는 Malanie III program을 이용하여 분석하였다. 전체 gel에서 약 1800개의 구분 가능한 protein spot이 나타났다. pH 4~7 범위에서 양적으로 차이나는 것 15개 중 복제한우 태반에서 증가되는 protein spot 5개와 감소하는 protein spot 10개를 골라 protein identification을 실시하였다. MALDI-TOF-MS를 이용하여 동정한 결과 phosphatidylinositol transfer protein-$\alpha$와 interleukin-18 등의 protein이 복제태반에서 발현이 증가되었고, 복제한우에서 발현이 감소되는 것으로는 vimentin, Rho-GDI-$\beta$, TRAST $\beta$-chain, ovarian sterol carrier protein 2, triosephosphate isomerase, tropemyosin beta chain, Aldose reductase 등으로 나타났다. 이러한 protein들은 inositol 지질 신호전달과 면역시스템, 세포분열, 산소 운반, steroidogenic 세포에서의 콜레스테롤 이동, 촉매 작용, 대사 작용 등에 중요한 역할을 하는 것으로 알려져 체세포 복제에 의한 태아사망 원인은 태반에서 이러한 protein들의 비정상적인 발현에 기인된 것으로 추정된다.

본 연구에서는 1.7kb 및 3.1kb bovine $\beta$-casein promoter의 유전자 발현 조절능력을 알아보기 위해 1 7kb 및 3.1kb bovine $\beta$-casein promoter에 human Type II Collagen 유전자를 연결해서 DNA microinjection으로 형질전환생쥐를 생산하였다. 총 8마리의 founder생쥐(1.7kb collagen : 5마리, 3.1kb collagen 3마리)를 생산하였고 이 founder생쥐와 wild type 생쥐를 mating시켜서 $F_1 및 F_2$ 새끼를 얻었다. $F_1 및 F_2$새끼들에서 human Type II collagen 유전자의 transmission rate는 약 50%로 Mendel의 법칙에 따라 분리되어 안정적으로 유전자가 염색체에 정착되어 있음을 확인하였다. 이들 $F_1 및 F_2$새끼 중 암컷들을 임신시켜 분만 후 5-10 일경에 유선조직을 포함하여 여러 조직으로부터 RNA를 추출하여 Northern blotting 및 RT-PCR 방법을 이용하여 Type II collagen mRNA의 발현을 분석하였다. 유선에서의 발현은 1 7 kb 및 3.1 kb line별로 각각 1 line씩 발현되지 않았고, 그 외 line에서는 모두 발현되는 것으로 확인되었다. 유선에서의 Type II collagen mRNA 발형양은 1.7 kb 및 3.1 kb bovine $\beta$-casein promoter사이에서는 큰 차이를 나타내지 않았으나 1.7 kb promoter 형질전환생쥐의 경우 유선 이외 조직에서도 발현되는 양상을 나타내었고, 3.1kb promoter line에서는 유선특이적으로 발현시키는 양상을 나타내었다. 그러므로 bovine $\beta$-casein promoter의 1.7 kb와 3.1 kb 사이에 유선특이적 발현을 유도하는 조절부위가 있을 것으로 추정된다.

Catamenial hemoptysis is a rare condition caused by thoracic endometriosis that presents as tracheobronchial or pulmonary endometriosis. While hormonal treatment may cause virilization and sterility, due to the antiestrogenic effect, its surgical removal via thoracotomy is a particularly invasive procedure and is not recommended as the first choice treatment in young woman. Successful surgical removal by video-assisted thoracoscopic surgery (VATS) has recently been reported, and may be indicated for young patients who at some stage would like to become pregnant. Herein, a case of a 25-year-old unmarried woman with catamenial hemoptysis, cured by VATS, is reported.

A study was conducted to improve the reproductive performance of Korean native goats. The length of estrous cycle and plasma progesterone concentrations during each cycles were determined by both radioimmunoassay and estrus behaviours, and the results were used in the early pregnancy diagnosis. The estrous cycles were classified into the short(l8 days or shorter, average 16.7 days), normal(19 to 22 days, average 20.9 days) and long(23 days and longer, average 23.8 days)cycle. The average length of the 19 estrous cycles was 20.8 days. Plasma progesterone concentrations in 12 normal cycles were the lowest(0.10 ng/ml) at estrus, remained high from 6 to 16 days(range : 4.43~7.93 ng/ml) and drastically decreased thereafter to reach minimal concentrations at the next estrus. Plasma progesterone concentrations were measured for early pregnancy diagnosis at 0, 10 and 20 days after mating in the 12 Korean native goats. Plasma progesterone concentrations in the pregnant goats at 20 days after mating were significantly higher than in the non-pregnant goats(p<0.001). Of the 12 goats, 10 were confirmed pregnancy by both progesterone concentrations and kidding. The accuracy of the pregnancy diagnosis based on plasma progesterone concentrations was 100% for positive as well as for negative.

The purpose of the present study was to examine the in vivo activity of oxytocin antagonist I (AI)in the nonpregnant estrous rat. Cannulas were placed in the jugular vein for infusing compounds and a water-filled balloon-tipped cannula placed in one uterine horn for assessing uterine activity. Uterine contractions were monitored with a Grass Polygraph and contractile activity determined as the integrated area for 10 minutes. Five minutes after infusing 5 ${\mu}\textrm{g}$ of AI, 100mU of oxytocin was given as an in bolus injection and repeated every hour for 5 hours. At five minutes, 1 and 2 hours after injection AI the uterine contractile response to 100 mU of oxytocin was significantly inhibited compared to controls(p<0.05). At 3, 4 and 5 hours no differences in response were detected compared to controls(p>0.05). These results in conjunction with other reports from our laboratory suggest that AI has the potential of being a potent and specific tocolytic for prevention of preterm labor in humans.
