Objective: The aim of this study was to establish whether differences in ovarian size exist between the right and the left ovary of the same individual in women with polycystic ovary syndrome. Methods: In total, 206 Korean women with polycystic ovary syndrome were included in this study. In all participants, a transvaginal or transrectal ultrasound examination was conducted in the early follicular phase of the menstrual cycle. Results: A significant linear correlation was found between the two ovaries with regard to antral follicle count and ovarian volume. The mean antral follicle count in the right ovary (26.75 ± 11.72) was significantly higher than that in the left ovary (23.98 ± 10.85), and the mean volume of the right ovary (11.06 ± 5.17 cm³) was significantly different from that of the left ovary (9.12 ± 4.89 cm³). Conclusion: Ovarian size is different between the right and the left ovary in women with polycystic ovary syndrome.

본 연구는 배변조영촬영 시 피폭을 받는 생식선(난소, 고환)에 대한 선량과 필터사용에 따른 선량의 차이를 측정하여 유용성을 분석한 것으로 그 결과는 다음과 같다. 난소와 고환이 받는 선량은 필터를 사용하지 않은 경우에 왼쪽 난소(Left Ovary) 23.4mGY, 오른쪽 난소(Right Ovary) 7.5mGy, 고환(Testis) 10.3mGy이었고, 부가필터만 사용한 경우 왼쪽 난소 22.4mGy, 오른쪽 난소 7.0mGy, 고환 9.5mGy이었다. 또한, 배변조영용 필터만 사용한 경우 왼쪽 난소 26.7mGY, 오른쪽 난소 8.4mGY, 고환 11.5mGy로 나타났으며, 두 가지 필터를 모두 사용한 경우 왼쪽 난소 20.5mGy, 오른쪽 난소 5.2mGy, 고환 7.5mGy이었다. 양측 난소와 고환 모두 필터의 사용에 따라 선량의 차이가 유의성이 있는 것으로 나타났다. 이는 필터의 사용 조합에 따라 필터를 사용하지 않았을 때를 기준으로 부가필터만 사용했을 때 왼쪽 난소는 선량이 10% 감소되었고, 오른쪽 난소 5%, 고환 8% 감소하였다. 배변조영용 필터만을 사용했을 때는 오히려 왼쪽 난소가 33% 선량이 증가하였고, 오른쪽 난소 9%, 고환은 12% 증가하였다. 두 가지 필터를 모두 사용하였을 때에는 왼쪽 난소는 2994 감소되었고, 오른쪽 난소 13%, 고환은 28% 감소하였다. 이와 같은 결과는 배변조명용 필터만을 사용했을 때는 오히려 선량이 증가하였으며 부가필터만 사용하거나 두 가지 필터 모두 사용하였을 때 현저히 선량이 감소하는 것으로 나타났다.

To elucidate the relationship between steroidogenesis and sex differentiation in the duck, plasma, testicular and ovarian testosterone, estradiol-$17{\beta}$ and progesterone concentration in male and female embryo of day 11 to 27 (just before hatching) of incubation and in 1- to 7-day-old male and female duckling were investigated by radioimmunoassays. Plasma estradiol-$17{\beta}$ concentration in female embryos declined from very high at days 11 and 15 of incubation and remained at low levels after hatching. Male plasma estradiol-$17{\beta}$ concentration were always lower than those of the female throughout this period. Plasma testosterone and progesterone concentrations in both sexes were low during the embryonic stage, but then increased to peaks 3 days and 1 day after hatching, respectively. Estradiol-$17{\beta}$ contents were much higher in the left ovary than the right ovary or testes throughout the experimental period. The estradiol-$17{\beta}$ content of the left ovary was very high at day 15 of incubation, and decreased gradually thereafter. Both in right ovary and testes, estradiol-$17{\beta}$ contents were always low. Testosterone and progesterone contents in the left ovary were low from day 11 to 23 of incubation, and reached a peak 1 day after hatching. Progesterone content in the right ovary and testes were low levels over time period examined. Testosterone and progesterone contents were much higher in the left ovary than the right ovary and testes. The present results clearly demonstrate that the capacity of the embryonic left ovary of duck to synthesize estradiol-$17{\beta}$ and testosterone is much higher than that of the embryonic testis. It is suggested that estrogen secreted from the embryonic ovary earlier than day 15 of incubation has an important role in female sexual differentiation in the duck, and the sex of the avian species is basically male with homozygous sex chromosome (ZZ).

1. The cows slaughtered at age of 3, 4, 6, 7, 8, and 9 years old were 1.5, 1.5, 15.0, 62.5 and 4.4% respectively. 2. The cows slaughtered at 351-450kg and more than 500kg were 60 and 28% respectively. 3. Best, very good, good and bad cows in nutritional condition were 1.6, 25.8, 62.9, and 9.7% respectively. Among the six cows which were bad nutrition, the two were with severe endometritis, the three were normal in genital function and one was on 70 days of pregnancy. 4.

Major axis, minor axis and thickness of right ovary were larger than those of left one both in Korean cattle and Holstein cows. Holstein cow had generally larger size of ovary than these of the Korean cattle.. 12. The left and right oviducts showed no difference in length, but Holstein had longer oviduct than Korean cow. 13. There was no difference in the length of uterine horn between right and left in the Korean cows, but the right was longer than the left in Holstein cows. 14. Holstein had longer horn and body of uterine than the Korean cows. 15.

A 4 year old female with acute lower abdominal pain was admitted with the diagnosis of periappendiceal abscess made by ultrasonography. At laparotomy, the appendix was normal, but the left ovary was twisted and necrotic. Appendectomy and left salpingo-oophorectomy were performed. The pathology of the appendix was normal, and the left tube and ovary were ischemic and had hemorrhagic necrosis. Pediatric adnexal torsion may be difficult to diagnosis clinically. Sonography is the preferred imaging study. It usually confirms a pelvic mass but may not establish the diagnosis. The correct diagnosis of adnexal torsion is often made at exploration. The most common erroneous diagnosis is acute appendicitis or periappendiceal abscess. Therapy for adnexal torsion remains controversial. While extirpation has been the standard of treatment in the past, there are current proponents of conservative therapy with adnexal sparing. Early diagnosis may lead to more frequent salvage of affected adnexa.

An 8-year-old Thoroughbred mare showing anestrus for longer than 6 months with left ovarian mass was referred to Veterinary Medical Teaching Hospital of Seoul National University. For 6 months, the mare had received 2 times hormonal therapies with $PGF_2{\alpha}$ and progesterone. The mare had not responded to these therapies and not shown estrous behavior. On rectal palpation, the left ovary was enlarged and contralateral ovary was small and inactive. Transrectal ultrasonographic examination of the left ovary revealed a mass composed of multiple, irregularly shaped follicles. Granulosa cell tumor (GCT) was suspected according to her history. Ovariectomy was performed through the left flank laparotomy with a standing position in a simple chute located outside of horse farm. The mass was diagnosed as GCT on histopathology. The mare was recovered without any problem and became pregnant next spring.

A 36-year old Korean woman consulted a clinic for a regular gynecological examination, and a mass was noticed in her pelvis. She was referred to the Asan Medical Center, Seoul where transvaginal ultrasonography confirmed a pelvic mass exceeding 10cm in diameter. She received total abdominal hysterectomy and bilateral salpingoophorectomy, and a borderline serous neoplasm with micropapillary features involving the left ovary and right ovarian serosa was histopathologically confirmed. In addition, a section of a nematode with numerous eggs was found in the parenchyma of the left ovary. The worm had degenerated but the eggs were well-preserved and were identified as those of Enterobius vermicularis. She is an incidentally recognized case of ovarian enterobiasis.

A case of ovarian teratoma is reported in a 11-year-old female Korean Jindo dog. Grossly, the left ovary was markedly enlarged ($5{\times}4{\times}4 cm in size$) and contained several cystic spaces filled with hairs and yellowish, fragile deratinous material on cross section. Histological observation of the hair and keratin containing cystic structures lined by stratified squamous epithelium, mature adipose tissue, and bone and cartilage is compatible with a diagnosis of ovarian teratoma, pyometra was also present in this dog. This is believed to be the first report on canine ovarian teratoma in Korea.

An elective laparoscopic ovariectomy on a healthy dog revealed a cystic structure in the left ovary. The surgical procedure was successful. Histopathological examination showed the presence of a teratoma adjacent to the ovary. To the best of the authors' knowledge, this is the first reported case of an ovarian teratoma removed by laparoscopic ovariectomy in a dog by using a multiport laparoscopic ovariectomy technique.
