Production of cloned pigs by somatic cell nuclear transfer (SCNT) has unlimited value for developing critical biotechnology such as xenotransplantation. Various efforts have been made to establish this technology, and several litters of live piglets have been produced after transfer of SCNT embryos. However, the efficiency is very low compared to piglet production by artificial insemination or natural mating. So far, most studies have been limited to in vitro production of SCNT embryos. This study was conducted to standardize a surrogate recipient (gilts) for transfer of SCNT embryos to improve pregnancy rate. Potential surrogate gilts over 7 months of age were checked for their estrous status by observing external signs; vaginal fluid, vulva redness, vulva swelling, and standing response to back pressure. Viscosity of vaginal fluid was evaluated and classified as none (0), medium (1), and strong (2). Vulva redness and swelling was respectively assessed by none or shrink (0), medium (1), strong (2). Back pressure was estimated by an immediate move (0), standing less than 10 sec (1), and standing over 10 see (2). And then ovulation status of each surrogate was classified as pre-ovulation (PO-17 surrogates), just prior to ovulation (JPO-20 surrogates), in ovulation (IO-12 surrogates), just after ovulation (JAO-14 surrogates) and after ovulation (AO-24 surrogates) at the time of surgery for embryo transfer (ET). Real-time ultrasonographic scanners have been used for pregnancy diagnosis by observing amniotic vesicles. The first pregnancy diagnosis was done on Day 30 after ET and then repeated 2-week interval. In the results, SCNT embryos transferred into JPO surrogates gave better pregnancy rates (45%) than others (4% to 11%) on Day 30 after ET. These result indicates that surrogate gilts in a status just prior to ovulation can offer optimal condition to establish pregnancy by transfer of SCNT pig embryos.

Sector scanner which has a conical end is used to image through the intercostal space because heart is protected by the ribs. Cardiac data published all around the world were also obtained by sector scanner. Although scanners being used in every small animal practice and animal hospital at college in Korea include convex ape and linear type, linear type is not appropriate f3r cardiac scan because of a wide contact surface. The purpose of this study is to establish ultrasonographic images of normal cardiac structures by measuring shape, size of reflectable cardiac structure according to restraint position in scanning normal heart of the puppies with 6.5 MHz convex scanner(SonoAce 4500, Medison, Korea) used in our veterinary teaching hospital, Seoul national university. Seventeen male and female puppies considered having healthy hear by X-ray and clinical examination are used feom April to July 1994. Scanning point selection of probe head and the distinction of imaged cardiac structures were accomplished by necropsy and cardiac scanning performed through thoracotomy under general anesthesia. At 10 o'clock position of transducer(at an angle of 30$^{\circ}$ between imaginary line from elbow joint to 3rd sternum and probe head, 60$^{\circ}$ from body surface, 4th intercostal space of right thorax) with the marker of scanner toward the head of dogs right atrium, left atrium and left ventricle were observed in 2, 3, 4, 5 intercostal space(2cm from the sternum) of experimental dog positioned ventrodorsally under general anesthesia. Under these conditions, the numerical values of imaged diastolic hear are as follows : the distance from skin to apex(mean$\pm$S.D) 47.53$\pm$6.94mm, thickness of left ventricular wall 6.00$\pm$1.60mm, length of left ventricle 16.27$\pm$5.31mm, width of left ventricle 15,33$\pm$4.25mm, length of left atrium 12.33$\pm$3.82mm, width of left atrium 11. 33$\pm$3.94mm, length of right atrium 1.00$\pm$2.41mm, width of right atrium 11.21$\pm$2.76mm and the area of left ventricle 270.92$\pm$109.81mm$^2$, area of left atrium 98.00$\pm$41.08mm$^2$, area of right atrium 62.75$\pm$21.04mm$^2$.

We experienced a case of nephropathy in chronic lead poisoning. The patient was 43-year-old male who has been working in secondary lead smelting plant for 14 years. On admission, blood pressure was 160/90 mmHg and the others were non-specific. In past history, he received chelating agent administration for lead poisoning irregularly and medicated for gout, and the blood lead concentration was $180.0{\mu}g/dl$ on 2 months before admission. Smoking habit has been 1 pack per day for 15 years and drinking habit has been 1 bottle of Soju per day but less flow. In liver function test, AST/ALT were 27/28 IU/l and $\gamma-GT$ was 456 IU/l. In blood test, Hb : 11.5 g/dl, Hct : 34.0% and basophilic stipplings were found in peripheral blood smear. Chest PA was normal and abdominal ultrasonographic finding was non-specific except fatty liver. In the test of lead exposure indices, $PbB:83.0{\mu}g/dl,\;PbU:28.3{\mu}g/l$, and blood ZPP was $300.0{\mu}g/dl$. And in renal function test, BUN : 31.4 mg/dl, blood creatinine : 2.7mg/dl, blood uric acid. 9.1 mg/dl, urinary albumin : 100.0 mg/g creatinine, urinary $\alpha_1-microglobulin$ : 120.5 mg/g creatinine, urinary $\beta_2-microglobulin$ : $183.8{\mu}g/g$ creatinine, and 24 hours urinary creatinine clearance was 31.9 ml/min. The ultrasonoguided renal biopsy showed the global sclerosis of glomerulus, moderate atrophy and loss of tubule, and interstitial fibrosis in light microscopy. There were diffuse losses of brush border of proximal tubule in electronmicroscopy.

For the study of the hemodynamic changes of the cranial pancreaticoduodenal arterial flow(cPDAF) in the dog with acute pancreatitis, acute pancreatitis was experimentally induced in 10 dogs by the injection of oleic acid into the accessory pancreatic duct. The parameters of cPDAF were measured by transcutaneous pulsed-wave Doppler ultrasonography. The hemodynamic changes included resistive indexe(RI), pulsatility index(PI) and maximum velocity (Vmax). Ultrasonographic scans were performed before the induction of pancreatitis and once daily for five days after the induction. The RI, PI and Vmax were increased with day as follows; the RI prior to induction was 0.625$\pm$0.096 (mean$\pm$SD), the PI was 1.117$\pm$0.289 and the Vmax was 0.349$\pm$0.094 m/s. After five days, the RI was 0.727$\pm$0.051 (p<0.0l), the PI was 1.480$\pm$0.284 (p<0.0l) and the Vmax was 0.585:$\pm$0.114 m/s (p<0.00l). These results show that there is some relation between the increase of the RI, PI and Vmax of cPDAF and the progress of acute pancreatitis in dogs. Therefore, the measurements of the hemodynamic changes of cPDAF may be a valuable technique for the evaluation of acute pancreatitis in dogs.

Objective: Ovarian reserve tests are commonly used to predict ovarian response in infertile patients undergoing ovarian stimulation. Although serum markers such as basal follicle-stimulating hormone (FSH) or random $anti-M{\ddot{u}}llerian$ hormone (AMH) level and ultrasonographic markers (antral follicle count, AFC) are good predictors, no single test has proven to be the best predictor. In this study, we developed appropriate equations and novel nomograms to predict the number of oocytes that will be retrieved using patients' age, serum levels of basal FSH and AMH, and AFC. Methods: We analyzed a database containing clinical and laboratory information of 141 stimulated in vitro fertilization (IVF) cycles performed at a university-based hospital between September 2009 and December 2013. We used generalized linear models for prediction of the number of oocytes. Results: Age, basal serum FSH level, serum AMH level, and AFC were significantly related to the number of oocytes retrieved according to the univariate and multivariate analyses. The equations that predicted the number of oocytes retrieved (log scale) were as follows: model (1) $3.21-0.036{\times}(age)+0.089{\times}(AMH)$, model (2) $3.422-0.03{\times}(age)-0.049{\times}(FSH)+0.08{\times}(AMH)$, model (3) $2.32-0.017{\times}(age)+0.039{\times}(AMH)+0.03{\times}(AFC)$, model (4) $2.584-0.015{\times}(age)-0.035{\times}(FSH)+0.038{\times}(AMH)+0.026{\times}(AFC)$. model 4 showed the best performance. On the basis of these variables, we developed nomograms to predict the number of oocytes that can be retrieved. Conclusion: Our nomograms helped predict the number of oocytes retrieved in stimulated IVF cycles.

목 적: 조기난소부전 환자의 10$\sim$20%에서 난소기능이 회복될 수 있다고 하며 간헐적으로 배란이 되고 심지어는 임신이 가능할 수 있다는 보고가 있다. 그러나 한국의 조기난소부전 여성의 임상적 특징과 배란가능성은 논의된 적이 없다. 이 연구의 목적은 한국인 조기난소부전 환자에서 자연 난포의 발생 빈도와 배란유도의 가능성을 평가하는 것이다. 연구방법: 특발성 조기난소부전으로 진단된 15명 여성의 전체 진료기록을 후향적으로 연구하였다. 환자별로 6번 이상의 초음파 검사를 시행하였고 36개월 이상의 기간 동안 추적관찰을 하였다. 또한 4명의 환자에서 6주기의 배란유도시도를 하였다. 조사항목은 초음파 검사에서 난포의 발견율, 자연 난포 성장률과 배란유도를 시행한 경우에 그 반응을 평가하여 결과를 분석하였다. 결 과: 15명 중 6명은 초음파상 난포가 발견되었나 (40%) 초음파 검사 당 난포 발견 빈도는 7%였다 (115회 중 8회). 6명 중 한 명은 초음파 추적관찰 상 배란이 확인되었고 나머지 5명은 크기에 변화가 없었다. 배란유도를 시도한 6명 중 성공적인 난포 성장이 관찰된 예는 없었다. 결 론: 한국인 조기난소부전 환자에서 난포의 발견율은 이전 서양 연구에 비하여 낮다고 생각되지만 관찰 방법에 차이가 있어 직접비교는 불가능하다. 배란유도의 성공율은 0%로서 이전 연구에서 발표된 수준보다 낮았다.
