IMF 시대를 맞이 하여 날로 어려워지는 국내외 현실은 동물병원을 위축되게 만들고 있다 하지만 이번 대한수의사회 차원에서 일본 수의사회의 협조로 애완고양이가 들어 온다고 하니 서울시 수의사회 달력에 고양이 그림을 게제토록 하였고 고양이를 동물 병원에서 키우고 있는 수의사로서 매우 기쁘고 또한 우려가 되어 사육의 경험을 토대로 몇가지 적어 보고자 한다. 사육의 동기는 1년에 400여명이 배출 되는 후배 수의사들과 경쟁을 하기 보다는 동업자의 선배 수의사로서 환축의 대상으로 확장하는 방안 중에 하나라 생각 되었고 일본이나 미국의 경우 내원하는 환축의 $60\%$정도가 고양이라는 사실이다. 일본의 경우 고양이는 사람들이 싫어하는 동물이었는데 개업 수의사들이 동물병원에서 키워 고객들이 보고 흥미를 느끼고 관심을 갖도록 하고 분양을 유도하여 고양이 숫자가 증가했으며 90년도에는 고양이 불임수술을 정부에서 보조지원할 정도가 되었다.

The objectives of this study were to investigate the genetic and phenotypic features of male sterile transformants by pollen-specific expression of diphtheria toxin gene and to find out inheritance patterns of transgene to the next generation. When backcrossed (BC) progenies were tested for expression of kanamycin resistance ($Km^R$), 9 lines out of 13 lines, except 4 lines ($BC_{1}5-13,\;BC_{1}5-23,\;BC_{1}5-28,\;BC_{1}5-32$), showed the ratio of $Km^R$ to kanamycin sensitive ($Km^S$), from 1:30 to all $Km^S$. As a result, they were much lower than Mendelian segregation of a dominant gene. To determine whether male sterility is a heritable and stable trait, 5 male sterile plants ($BC_{1}5-13,\;BC_{1}5-14,\;BC_{1}5-23,\;BC_{1}5-32,\;BC_{1}5-33$ lines) which had different transgene copy numbers were backcrossed as female parents with pollens from wild type. To confirm the existence of the DTx-A gene in the genome of the progenies, PCR was conducted using specific primers of the DTx-A coding region. A PCR band of 428 bp was obtained from each generation, which is the predicted size of the DTx-A gene fragment. Trangenes were inherited to the next $BC_4T_0$ progenies and showed male sterility, however, based on the copy numbers of DTx-A gene male sterile plants did not show predicted ratio. When male sterile plants were backcrossed with fertile plants, fruit capsule sizes and seed settings were relatively reduced from those of selfing wild type plants. The fruit sizes and seed settings were reduced in proportion to the increase in the copy number of DTx-A gene.

Objective: To examine determinants of successful pregnancy and evaluate COH-IVF outcomes of infertile patients after conservative surgical treatment of borderline ovarian tumor (BOT). Methods: In women of BOT (n=93), from January 1995 to December 1999, 44 of 93 women underwent conservative surgical treatment. From theses 44 women, patients characteristics, surgical and histological parameters were compared between 14 women who conceived and 30 women who failed to conceive. For 5 infertile women of 30 women who failed to conceive, 10 attempt IVF cycles were analysed; clinical pregnancy rate (CPR), implantation rate (IR) and live birth rate (LBR). Results: Women who conceived tend to be younger (25.9 vs 27.0 years) and lower serum CA-125 level (59.7 vs 72.9) compared to women who failed to conceive without significant difference. For 8 cycles out of 10 attempt IVF cycles, except for 2 cancellation cycles, the mean number of oocytes retrieved was 5.6 (range 2$\sim$16) with a mean fertilization rate of 74.4%. The CPR, IR and LBR per embryo transfer were 50.0% (4/8 cycles), 31.6% (6/19) and 50.0% (4/8 cycles) respectively. During the mean follow-up period after COH-IVF initiation, 29.6 (range 14$\sim$61) months, no recurrence was found. Conclusion: No determinant of successful pregnancy was found after conservative treatment for BOT. COH-IVF may be considered for infertile patients after conservative treatment of BOT. However, larger clinical studies with longer follow-up are necessary to evaluate the safety and efficacy of COH-IVF. All patients should be informed of the potential risks associated with ovarian hyperstimulation and close follow-up is necessary after COH-IVF.

진단적 복강경을 하지 않으면 자궁내막증의 진단이 불가능하다는 점은 의사들이 해결해야 할 과제 중 하나이다. 아직까지는 자궁내막증을 진단할 수 있는 획기적인 표지자가 없기 때문에 CA-125 같은 종양 표지자의 혈중 농도를 측정하였으나 진단 도구로 이용하기에는 한계가 있다. 이러한 이유로 초기 자궁내막증을 진단할 수 있는 방법을 연구하기 위한 여러 시도들이 있었는데 특히 자궁내막증 1, 2기 환자에서 병의 초기 상태에 복강경적 치료를 하였을 경우 자연 임신 성공률이 2배 가까이 높은 것으로 보고되었기 때문에 불임 여성에 있어 자궁내막증의 진단 시기는 임상적으로도 그 중요성이 매우 크다고 할 수 있겠다. CA-125는 자궁내막증 환자의 추적관찰에 있어 특이도가 높은 편이며 효용성이 있는데 특히 수술적 치료 후 장기적으로 병의 활성 혹은 재발을 평가하는데 있어 유용하다. 무작위적인 임상 연구 결과 자궁내막증과 관련된 불임이나 통증은 수술적 치료시 분명한 이득이 있는 것으로 보고된 바84 자궁내막증은 적절한 진단과 치료가 중요한 질환이라는 점을 다시 한번 상기해야 한다. 또한 병의 진행에 따른 여러 면역학적인 변화들이 확인되면서 자궁내막증의 진단에 있어 면역학적 표지자의 중요성이 부각되고 있다. 그 중에서도 복막액이나 혈청 내 사이토카인은 진단 도구로서 그 가능성에 주목을 받고 있으며 이에 대한 대규모 연구가 추후 필요할 것으로 사료된다. 최근의 면역학적 발견과 DNA 기술 발전은 자궁내막증의 진단에 있어 핵심적인 screening 도구의 발견에 일조할 것이며 이러한 기술적 발전을 근간으로 하여 머지 않아 획기적인 표지자가 개발될 것으로 기대한다.

In Citrus, an $F_1$ segregation population of 150 plants was constructed from a cross between 'Kiyomi' (C. unshiu ${\times}$ C. sinensis) carrying the male sterility trait and 'Jinkyool' (C. sunki). Sequence-related amplification polymorphism (SRAP) combined with bulked segregant analysis was used to develop markers linked to male fertility. In the $F_1$ population, 66 out of 150 seedlings had aborted anthers and the ratio of male sterile plants to fertile plants in the progenies matched the expected Mendelian segregation ratio of 1:1 ($x^2$ =2.16 at p=0.05). From the profiling of the 197 SRAP primer sets, three SRAP primer sets (F4/R27, F39/R60, and F15/R37) that were closely linked to the target trait were identified and successfully converted into a sequence characterized amplified region (SCAR) marker for selection of male fertility in citrus. The SCAR marker, using the pMS 33U/pMS 1462L primer set specifically, produced a single 1.4-Kb fragment that was linked to male fertility. Our results suggested that this SCAR marker can be useful for marker-assisted selection of male sterile individuals in breeding $F_1$ progenies in Citrus.

Objective: To evaluate the significance and efficacy of trans-cervical fallopian tube catheterization (TFTC) in diagnosis and optimal treatment modality for tubal blockage. Methods: The retrospective study was performed in those underwent TFTC from January 2005 to December 2009. A total of 342 fallopian tubes in 215 patients which showed tubal blockage in hysterosalpingography (HSG), were subjected to TFTC. Recanalization rate (RR) was compared according to portion of tubal blockage; proximal, isthmic and distal portion and blockage type; tapering, concave, and convex type. Results: In total, RR was 72.5% (248/342 tube). According to the portion of tubal blockage, RR was 83.8% in proximal, 45.6% in isthmic and 100% in distal portion. RR was 92.3% in tapering, 80.2% in concave and 25.5% in convex type, respectively. There were 98 pregnancies in 156 patients after successful recanalization, which shows 62.7% pregnancy rate. Conclusio: TFTC were capable of recanalizing tubal blockage in 248 of 342 tubes in 156 of 215 patients (72.5%). The RR was increased with proximal portion and tapering type tubal blockage.

본 실험은 성숙가토의 정자와 정장의 항원성을 조사하여 면역적 불임원인 규명에 필요한 기초자료를 얻고자 시도하였다. 인공질로 채취한 정액을 원심분리하여 얻은 정자와 정장을 항원으로 사용하였으며 항원성의 측정방법은 크로마토그라프에 의한 단백질 분리, SDS-PAGE, HPLC, 한천확산법, 전기영동, 수동적혈구응집방법 및 부동화시험이었다. 얻어진 결과는 다음과 같다. 1. SDS-PAGE 전기영동시 정상가토 정장에서 약 23개의 단백질이 분리되었고, 그중 분자량이 약 20,000되는 단백질부분이 정관절제 수술한 정장에서 나타나지 않았다. 2. 정상가토 정장을 HPLC를 이용한 분석에서 3개의 peaks을 볼 수 있었고, 정관절제수술한 것에서는 peak 1에 해당하는 단백질이 소실되었다. 3. 한천확산시험에서 정상정장은 이종혈청과는 4개의 침강선을 나타냈고, 전기영동에서는 7개의 침강선을 나타냈다. 4. 이종면역에서 정자 및 정장은 항체가 상승이 용이하였지만, 동종면역시는 추가면역이 필요하였으며 개체간의 역가차이를 보였다. 정자면역한 자성가토에서는 수동적혈구응집반응을 나타냈지만, 한천확산 및 전기영동반응은 보이지 않았고, 같은 처치를 받은 웅성가토에서도 역시 같은 반응양상을 나타냈다. 5. 동종 및 이종항혈청을 이용한 교차전기영동방법으로 정장의 항원적 구성요소를 구별할 수 있었다. 사출된 정액에서 분리된 정장은 일부 항원을 포함하고 있었으며 이는 성숙한 정자에서 기인한 것으로 사료되었다.

Pulmonary endometriosis is an uncommon disease, and usually detected by catamenial hemoptysis. Treatment of pulmonary endometriosis may be medical(hormone therapy) or surgical. Since hormone therapy may cause sterility, most of patients who wish to conceive usually choose surgical resection. Although video-assisted thoracic surgery(VATS) has advantage of small scar, reducing postoperative pain and shortening hospital stay, it is not easy to locate the precise lesion and resect whole endometrial tissue not to be remained. 17 years old female with catamenial hemoptysis was treated sucessfully with a partial resection of the lung using VATS, and has been asymptomatic for 7months since the operation.

A complete septate uterus with cervical duplication and a longitudinal vaginal septum is a rare uterine malformation. The dissection of the septum can be difficult because it is difficult for hysteroscopists to find out initial point, direction and final point of a complete septum. This study aimed the introduction of more efficient surgical procedure using a balloon with methylene blue. We have experienced three cases with a complete septate uterus. We performed hysteroscopic dissection of a complete uterine septum using a balloon with methylene blue and obtained good reproductive outcomes. So we report three cases with a brief review of literatures.
