Testicular feminization syndrome (TFS) is a genetic disorder due to androgen insensitivity of the target organs. The most common clinical presentation of complete TFS is inguinal hernia in the infant or primary amenorrhea in the adolescence. A 7-year old phenotypically female patient was seen with a complaint of a right inguinal mass. Under the diagnosis of right inguinal hernia, high ligation was performed. Six months later, the patient showed a left inguinal mass. On operation, the mass looked like a testis. The external genitalia were normal female, but a uterus and ovary were not identified. Chromosome study showed a 46, XY karyotype and the levels of serum testosterone and dihydrotestosterone were increased after HCG stimulation. The patient was diagnosed as complete TFS and underwent bilateral gonadectomy 6 months later.

A total of 301 Thoroughbred mares were investigated the characteristics of breeding in the local areas in Jeju during the period from February 2000 to July 2001. The pregnancy rate and foaling rate in 143 mares were 93.0%, 72.0%, respectively, and mean gestational length was 339.3 days in 2000. The pregnancy rate in 158 mares was 86.7% in 2001. Mature follicles were ovulated in right(46.0%), left(45.2%), and bilateral(7.8%) ovary. The incidence of multiple pregnancies in 158 mares between 15 days and 45 days after mating were 89.3%(single), 10.1%(twin), and 0.6%(triple). The incidence of EED was 13.3%. Also uterine cyst and fluid had an bad influence on mare's pregnancy. These results suggest that regular monitoring of the pregnancies and maintaining of good uterine condition improve the pregnancy rates and foaling rates during breeding season.

A six-year-old, female Jin-do dog was referred for the recurrence of vaginal prolapse. Less than 7 months previously, the dog with the vaginal prolapse had been treated with hormone therapy because ultrasonography had identified a single follicular cyst in the left ovary. Three months after the first visit, the dog came into heat and the vaginal prolapse recurred. Ultrasonography showed multiple follicular cysts in both ovaries and radioimmunoassay detected a plasma estradiol-$17{\beta}$ concentration of 13.3 pg/ml. Treatment involved the repositioning of the vaginal prolapsed, ovariohysterectomy and the resection of the protruding tissue. The dog had been completely recovered two months later after the treatment.

A 11-year, 9-month-old female Shih-tzu was referred for evaluation of the body conditions. According to the physical examination and ultrasonography, the left ovarian mass was detected. For the removal of ovarian mass, an ovariohysterectomy was performed. Grossly, the ovarian mass was full of hairmatrix on the cut surface of the mass. Histopathological findings revealed a characteristic of teratoma, such as laminated keratines, hair, sebaceous glands, neuron tissue, differentiated bone and cartilage. The ovarian mass was well-differentiated components of 2 germ layers, and diagnosed as a mature teratoma.

During three months from December 1967 to February 1968, 1867 Korean native cows slaughtered in pusan abattoir were investigated for studying the incidence of cystic ovaries. The results obtained in this experiment are summarized as follows: 1. The average frequency of cystic ovaries in 1867 Korean cows was 17 cases, or 0.91%. 2. In 17 cases 1, or 0.3%, occurred in cattle from 1 to 3 years of age; 4 or, 1.02% in four; 7 or, 2.02% in five; 2 or, 0.63% in six; and 3, or 0.63% occurred between 7 and 9 years of age. 3. The incidence of cysts in the respective ovaries, the left ovary was cystic in 23.5% of the cases, the right one in 41.2% and both ovaries in 35.3%. 4. According to the histological findings of cystic ovaries, follicular cysts were 88.2% and luteal cysts 11.8%.

A total of 1200 Korean native cow and 240 dairy cow genitalia were collected during the slaughtering process in Seoul and Kwang Ju abattoir and were examined from July 1985 to March 1986. Ovarian follicles were classified as cystic if the diameter was greater than 2.5cm or if follicles were multiple. In order to investigate the ovarian cysts, anatomical and histological examinations were performed. In addition progesterone and estrogen level in different types of cystic follicular fluid and serum were measured by radioimmunoassay. The results were summerized as follows: 1. The incidences of ovarian cysts were 2.0% in Korean native cow and 7.9% in dairy cow. 2. In distribution of cysts in the left, right and both ovaries, the most encountered ovary was right one. The frequency was 45.8% in right ovaries, 33.4% in left ovaries and 20.8% in both ovaries in Korean native cow. On the contrary the frequency was 42.1% in right ovaries, 31.8% in both ovaries and 26.3% in left ovaries in dairy cow. 3. Six speciemens (25.0%) of Korean native cow and six specimens (31.6%) of dairy cow were associated with corpora lutes in both ovaries. 4. The luteinization of theca layer was most significant in the group 2Aa (71.4%) and 2Ba (38.5%) which associated with no granulosa cell and corpora lutea in the same cystic ovaries. 5. Correlation of progesterone concentration between cystic fluid and serum was found only in the group 2Aa and 2Ab (r=0.86). Progesterone and estrogen concentrations in cystic fluid were closely related to the degree of degeneration of granulosa cell layer. The cystic follicles that consist of thickened theca and degenerated granulosa cell layers contained a large amount of progesterone, and small amount of estrogen. In conclusion, various types of ovarian cysts with various levels of progesterone and estrogen were observed in Korean native cow.

This study is a retrospective analysis of 1244 cases of the inguinal hernia in children under the age of fifteen years who were operated at the department of pediatric surgery, Inje University Busan Paik Hospital from March, 1997 to February, 2007. The ratio of male to female was 3.6:1. The type of hernia was indirect in all of the cases. The hernia was on the right side in 656 cases (53.9 %), left side in 467 cases (37.5 %), and bilateral in 121 cases (9.7 %). The hernia presented most frequently in infants under age 12 months; 364 cases (29.2 %). Fifty-nine cases (21.7 %) were in female and 305 cases (31.3 %) in male. There were 428 cases (33.6 %) in 1-3 years age group, 295 cases (23.7 %) in 4-6 years, 112 cases (9.0 %) in 7-9 years, 39 cases (3.1 %) in 10-12 years and 16 (1.2 %) in 13-15 years. The content of hernia sac was small bowel (59 %), omentum (31 %) in males and the ovary and tube (54 %) and small bowel (26 %) in female. The incidence of combined operation at the time was 3.2 %, and consisting of orchiopexy (67.5 %), frenulotomy (12.5 %), appendectomy (10 %), circumcision (5 %), and fistulotomy (5%). The incidence of combined disease was 2.8 % and consisting of undescended testis, Hirschsprung's disease, idiopathic hypertrophic pyloric stenosis, imperforate anus, and congenital heart disease. After unilateral inguinal hernia repairs, contralateral hernias developed in 34 patients. The laterality of the primary site of hernias were left in 19 cases (55.8 %), and right 15 cases (44.1 %). The 936 cases (75.2 %) were operated under general anesthesia; Mask bagging 663 cases (53.2 %), endotrachea intubation 257 cases (20.6 %), and laryngeal mask 16 cases (1.2 %).

Stellantchasmus falcatus (Digenea: Heterophyidae) is first reported from Cambodia through recovery of the metacercariae from mullet fish and adult flukes from an experimentally infected hamster. We purchased 7 mullets, Chelon macrolepis, in a local market of Phnom Penh, Cambodia, and each of them was examined by the artificial digestion method on May 2010. The metacercariae of S. falcatus were detected in all mullets (100%) examined, and their average density was 177 per fish. They were elliptical, $220{\times}168{\mu}m$ in average size. They were orally infected to an hamster to obtain adult flukes. Adults recovered at day 10 post infection were observed with a light microscope and a scanning electron microscope (SEM). They were small, $450{\times}237{\mu}m$ in average size, had a small oral sucker ($41{\times}50{\mu}m$), subglobular pharynx ($29{\times}21{\mu}m$), slender esophagus ($57{\mu}m$), long and thick-walled expulsor ($119{\times}32{\mu}m$), spherical ovary ($58{\times}69{\mu}m$), and 2 ovoid testes (right: $117{\times}74{\mu}m$; left: $114{\times}63{\mu}m$). Eggs were small, yellow, and $23{\times}12{\mu}m$ in average size. In SEM observations, tegumental spines were densely distributed on the whole tegument, and single small type I sensory papillae were distributed around the lip of oral sucker. The small ventral sucker was dextrally located and had 8 type I sensory papillae on the left margin. It has been first confirmed in the present study that the mullet, C. macrolepis, is playing the role of a second intermediate host of S. falcatus in Cambodia.
