  • In this report, laparoscopic ovariohysterectomy (LOHE) was performed on two, healthy, intact female dogs. Three ports, umbilical port for placing the laparoscope and the left and right paramedian instrument ports were placed into the abdominal cavity. First, in order to isolate the right ovary, the vascular pedicle was coagulated by activating the universal bipolar forceps. Then, the pedicle and suspensory ligament were transected by the bipolar electrocauterization scissors. In the same manner, the left ovary was isolated. The uterine body and the uterine arteries were coagulated bilaterally and transected just rostral to the cervix. The isolated ovaries and uterus were exteriorized through the left paramedian instrument port, which was extended by approximately 1 cm to allow for tissue removal. The skin and subcutaneous tissue were closed in a routine manner. Surgical times for LOHE in two dogs were 35, 40 min respectively. Total length of abdominal incision was shorter than 3 cm in two dogs. No clinical complications related to the LOHE were observed during 1.5 years after surgery. The LOHE is an alternative surgical technique that deserves further investigation.

  • A necropsy of a primiparous, 4-year-old, Himalayan tahr (Hemitragus jemlahicus) was performed in September 8, 2009. Typical appearances of ovaries, oviducts, uterine horns, cervix and caruncles were well shown. Five cervical folds were present in the cervix. Cervical opening can be reached in the length of less than 15 cm from the entrance of vagina. Development of two follicles was found in the left ovary even though breeding season of this species naturally starts in late November. The reproductive organs of a primiparous, 3-year-old, Corriedale sheep showed that differences in the length and morphological appearance of cervix exist between two species. Comparative understanding of reproductive systems in Himalayan tahr and Corriedale sheep could help advancing assisted reproductive technologies in feral goats.

  • The purpose of this study was to assess for re-breeding concentrate period in postpartum in milking cows. The 48 cows aged $3.5{\sim}5.5$ years and of $400{\sim}600\;kg$ body weight were examined every 3rd day from 15 to 36 day postpartum. Blood samples for progesterone and estradiol $17{\beta}$ hormone analyses were withdrawn from the coccygeal vein every third day until the end of the experiment. The ovarian follicular numbers were verified and measured using a multi frequency probe. The least squares means are presented for each day by GLM of SAS. The results showed that ovary lengths (right ovary; $1.64{\pm}0.62\;cm$, left ovary; $1.44{\pm}0.46\;cm$) were similar in right and left ovary activity level during estrous cycle of postpartum cows. We were judged completed uterus on day at $2.31{\pm}0.17\;cm$ level of cervix diameter. And we were monitoring started at $6.44{\pm}2.03\;cm$ from day 15 after postpartum. The results showed that mean plasma concentration of progesterone (3.28 ng/ml) in large follicle gradually increased days 30 in postpartum. And, monitoring of estradiol 176 (22.18 pg/ml) hormone during postpartum period would be useful to predict the ovarian and uterus activity for re-breeding in postpartum milking cows. From these results, we conclude that cervix diameter (mean: 2.31 cm) was very important for reproductive organ recovery standard level of postpartum milking cows, hormone secretion level ($P_4$: 3.28 ng/ml, $E_2$: 22.18 pg/ml) and body condition score ($2.5{\sim}2.75$) level about 30 days in postpartum period.

  • Background: The polycystic ovary syndrome (PCOS), characterized by hyperandrogenism and chronic anovulation, is a common endocrine disorder in women. PCOS, which is associated with polycystic ovaries, hirsutism, obesity and insulin resistance, is a leading cause of female infertility. In this condition there is an imbalance in female sex hormones. All the sequelae symptoms of PCOS gradually lead to cancer in the course of time. It is heterogeneous disorder of unknown etiology so it is essential to find the exact cause. Materials and Methods: In this study both invasive and non-invasive techniques were employed to establish the etiology. Diagnosis was based on Rotterdam criteria (hyperandrogenism, ovulatory dysfunction, PCOM) and multiparameters using buccal samples and dermatoglypic analysis and cytogenetic study for 10 cases and four age and sex matched controls. Results: In clinical analysis we have observed the mean value of total testosterone level was 23.6nmol/L, total hirsutism score was from 12-24, facial acne was found in in 70% patients with 7-12 subcapsular follicular cysts, each measuring 2-8 mm in diameter. In dermatoglypic analysis we observed increases in mean value ($45.9^{\circ}$) of ATD angle when compared with control group and also found increased frequency (38%) of Ulnar loops on both fingers (UU), (18%) whorls on the right finger and Ulnar loop on left finger (WU) and (16%) arches on right and left fingers (AA) were observed in PCOS patients when compared with control subjects. Features which could be applied as markers for PCOS patients are the presence of Ulnar loops in middle and little fingers of right and left hand. The buccal micronucleus cytome assay in exfoliated buccal cells, we found decrease in frequency of micronuclei and significant increases in frequency of karyolysed nuclei in polycystic ovarian syndrome patients. Chromosome aberration analysis revealed a significant increase in frequency of chromosome aberrations (CAs) in PCOS patients when compared with controls. Conclusions: From this present work it can be concluded that non-invasive technique like dermatoglypics analysis and buccal micronucleus cytome assays with exfoliated buccal cell can also be effective biomarkers for PCOS, along with increased CAs in lymphocytes as a sign of genetic instability. There is a hypothesis that micronuclei and chromosomal aberrations could have a predictive value for cancer. From this present work it can be concluded to some extent that non-invasive technique like dermatoglypics and buccal cell analysis can also be effective for diagnosis.

  • Gastric cancer is rare during pregnancy, and often advanced upon presentation. A Krukenberg tumor presents a diagnostic and therapeutic challenge in the pregnant patient. We present a case of a 38-year-old woman at 22 weeks' gestation who presented with worsening epigastric pain, and was found to have a left pelvic mass on ultrasound, which was confirmed by magnetic resonance imaging. She went into active labor and delivered a viable infant via vaginal delivery. An exploratory laparotomy revealed a large mass originating from her left ovary and diffuse thickening of the lesser curvature of the stomach. Frozen section investigation revealed the presence of signet cell adenocarcinoma. Subsequent upper endoscopy showed linitis plastica, while biopsy confirmed the presence of adenocarcinoma. In conclusion, the occurrence of gastric cancer in pregnancy is rare despite extremely common symptoms. The management poses a challenge because of the need for early treatment, and the continuation of the pregnancy.

  • A case of schistosomus reflexes in Korean native female calf was observed macroscopically and radiographically. The results were summarized as follows. 1. The abdominal visceral organs were exposed. 2. The vertebral column bent laterally to the left, and the sacrum approached to the cranium by reflected caudal lumber vertebrae, presenting S-shaped lateral twisting of the vertebrae. 3. The right ribs reflected laterally and dorso-cranially from the 7th rib to 13th rib. The left ribs bent caudally from 8th rib to 13th rib. 4. The length of rudimentary 6th right rib was one half of normal size and the 7th right rib was one third. 5. The sternum was bifid split from the fourth sternebra through the xyphoid cartilage. 6. The diaphragm was intact and thoracic cavity was reduced in size. The lung and heart severely deformed in shape and size. 7. The liver markedly deformed in shape and thickness. 8. The pelvic cavity was reduced in size by compression laterally to the left. 9. The uterus horn, ovary, urinary bladder, and urethra were severely deformed in the shape and position.

  • A differential diagnosis between the true hermaphroditism (TH) and mixed gonadal dysgenesis (MGD) has important clinical implications for gender assignment and the decision for early gonadectomy; however, variable clinical and histological features frequently lead to the confusion of TH with MGD. A 17-month-old boy was presented with proximal hypospadias with chordee and right non-palpable testis in his scrotum. He also had right auricular anomaly including a separated tragus with skin tag. Left testis was well palpable in his left scrotum. Diagnostic right inguinal exploration showed Mullerian structures such as a gonad like an ovary and a fallopian tube with a uterus, which were removed. Repair of hypospadias and right auricular anomaly was also done. Following ultrasonography (USG) showed a normal looking testis in left scrotum. His chromosome was 45, XO/46, XY. We report a difficult case of mixed gonadal dysgenesis mimicking true hermaphroditism which combines ipsilateral congenital auricular anomaly.

  • Follicle stimulating hormone (FSH) stimulates follicle growth, and inhibits the follicle atresia in the immature rodent ovaries. The present study was carried out to know the histological changes of ovarian follicles after FSH treatment in the prepubertal mice. Ten i.u. of recombinant FSH was i.p. injected on 3 weeks old mice. After the treatment, at 1, 2 and 3 days, left ovaries were collected for the histological study. The atretic ratio of preantral follicles increased with time after FSH treatment. However, in the case of antral follicles, there was no significant change in the ratio. The degenerating follicles contained apoptotic granulosa cells, macrophage, and polymorphonuclear leukocytes in the follicular cavity. The present results suggest that follicular degeneration caused by FSH hyperstimulation could be mediated by apoptosis as well as the acute inflammation.

  • Teratomas arising from totipotential primitive germ cell are composed of 2 or 3 germ cell layers. We reviewed the records of 166 children who underwent the operation for teratoma from Jan, 1990 through April, 2007. There were 40 boys and 126 girls (average age $6.93{\pm}5.83$ years). Primary sites were ovary (n = 88), sacrococcygeum (n = 24), testis (n = 16), retroperitoneum (n = 16), mediastinum (n = 8), brain (n = 4), thymus (n = 3) and a single tumor involved the adrenal gland, neck, middle ear, oropharynx, stomach, pelvis, omentum, chest wall and scalp. Teratomas were mature in 141 patients, and immature in 25. Six patients who had ovarian immature teratomas grade 2 or 3 with peritoneal gliomatosis underwent adjuvant chemotherapy. During follow up period, 6 mature teratomas recurred at sacrococcygeal area (n = 1) and contralateral ovary (n = 5). Five patients of them underwent reoperation and diagnosed as a mature teratoma, but one who had underwent a left salpingooophrectomy with right ovary cystectomy at initial operation was observed carefully. Teratomas were dominant in female patients and developed at various organs. Complete excision was needed for good prognosis. In case of immature teratoma, complete excision and appropriate chemotherapy according to grading can contribute to favorable results.

  • Eight species of bithyniids, Bithynia leachi, B. tentaculata, B. siamensis, B. misella, B. kiusiuensis, B. striatula, Bithynia sp. from Nepal and Gabbia australis were collected from 1957 to 1988. The samples were relaxed with pentobarbital and fixed with 70% ethyl alcohol. There was no significant difference in internal structure of soft body, except the male reproductive system. The alimentary canal of the bithyniids consisted of mouth, buccal mass, esophagus, stomach, intestine, rectum and anus. The heart consisted of an auricle and a ventricle, located at left side of the stomach in the visceral hump. The ctenidium comprised 40-70 subtriangular lamellae. Eight ganglia were located around upper esophagus. The female reproductive system comprised ovary, oviduct, spermaaheca, and albumin gland. The male reproductive system was composed of testis, seminal vesicle, prostate gland, vas deferens, penial duct, and penis in order. Male was distinguished externally from the female by a bifid penis.
