Objectives: This study was designed to investigate the effects of Yongdamsagantang on the polycystic ovary(PCO) induced by estradiol valerate(EV) in rats. Methods: After administrating Yongdamsagan-tang to PCO induced rats, we measured the weight of body, ovaries, adrenal glands, and uterus of rats. The observation through naked eye and histopathological observation of ovaries were evaluated. Also, the number of follicle and corpora lutea and content of androstenedione(ADD) and total estrogen were evaluated. The expressions of nerve growth factor(NGF) and corticotropin releasing factor(CRF) were analyzed by immunohistochemistry. The breeding rate and number of implantation with normal male rats were evaluated. Results: - The weight(mg) of ovaries in YST treated group($73.8{\pm}7.6$) was significantly increased(p<0.001) compared with control group($54.3{\pm}4.5$). - The number of mature follicles in YST treated group($7.3{\pm}2.4$) was significantly increased(p<0.01) compared with control group($3.5{\pm}1.2$). - The number of atretic follicles in YST treated group($9.0{\pm}1.5$) was significantly decreased(p<0.01) compared with control group($13.4{\pm}3.8$). - The number of cystic follicles in YST treated group($3.1{\pm}1.1$) was significantly decreased(p<0.01) compared with control group($6.0{\pm}2.0$). - The number of corpora lutea in YST treated group($3.8{\pm}2.1$) was significantly increased(p<0.001) compared with control group($0.3{\pm}0.7$). - The expression of NGF-immunoreactive cells in the ovarian granulosa cells in YST treated group was lesser observed than control group. - The expression of NGF-immunoreactive cells in the adrenal cortex in YST treated group was lesser observed than control group. - The breeding rate in YST treated group(100 %) was significantly increased (p<0.05) compared with control group(50 %). - The number of implantation in YST treated group($6.4{\pm}4.7$) was significantly increased(p<0.05) compared with control group($1.4{\pm}2.6$). Conclusions: We concluded that Yongdamsagan-tang activates the maturation of follicles, normal ovulation, breeding rate and number of implantation. Therefore, this may be effective for the treatment of anovulation, amenorrhea and sterility of PCOS patients.

Objective: To investigate the histologic features of the uterus and adnexae extirpated from gender identity disorder (GID) patients that received depot androgen injection. Methods: We reviewed the histologic findings of the uterus and adnexae removed from sixteen GID patients, who had taken depot androgen injection for 5~168 months. Results: Fourteen patients (87.5%) showed the atrophied epithelium of exocervix and all of 16 patients (100%) showed the atrophy of endometrium. Seven patients (43.7%) showed multiple cystic follicles in the ovarian cortex and 6 patients (37.5%), 3 patients (18.7%) showed corpus albicans and corpus luteum, respectively. Conclusions: Exogenous androgen induced atrophy of cervix and endometrium. This effect was more prominent in the endometrium. In addition, PCO-like histologic features were observed in the ovary.

Adenocarcinomas (AC) are the most frequently encountered carcinomas. It may be quite challenging to detect the primary origin when those carcinomas metastasize and the first finding is a metastatic tumor. This study evaluated the role of sex hormone binding globulin (SHBG) positivity in tumor cells in the subclassification and detection of the original organ of adenocarcinomas. Between 1994 and 2008, 64 sections of normal tissue belonging to ten organs, and 116 cases diagnosed as adenoid cystic carcinoma and mucoepidermoid carcinoma of the salivary gland, lung adenocarcinoma, invasive ductal carcinoma of the breast, adenocarcinoma of stomach, colon, gallbladder, pancreas and prostate, endometrial adenocarcinoma and serous adenocarcinoma and mucinous adenocarcinoma of the ovary, were sent to the laboratory at the Department of Pathology at the Yuzuncu Yil University School of Medicine, where they were stained immunohistochemically, using antibodies against SHBG. The SHBG immunoreactivity in both the tumor cells and normal cells, together with the type, diffuseness and intensity of the staining were then evaluated. In the differential diagnosis of the adenocarcinomas of the organs, including the glandular structures, impressively valuable results are encountered in the tumor cells, whether the SHBG immunopositivity is evaluated alone or together with other IHC markers. Further extensive research with a larger number of cases, including instances of cholangiocarcinoma and cervix uteri AC [which we could not include in the study for technical reasons] should be performed, in order to appropriately evaluate the role of SHBG in the differential diagnosis of AC.

A female French Bulldog was referred to Veterinary Medical Teaching Hospital, Chungbuk National University. In case, alopecia and erythema nodosum were the main complaints in a 16 months old female dog. Ventral alopecia and dorsal erythema nodosum have been presented on skin lesions for 8 months. There were no specific change with CBC and blood chemistry but plasma estrogen concentration was 68 pg/ml and cornified superficial epithelial cells were detected above $90\%$ by cytology examination of vaginal smear preparation. Ovarian cyst was detected by ultrasonography in the left ovary. Cystic diameter was $14.2\times12.0mm$. Therefore, we diagnosed as unilateral multiple follicular cysts. The dog was treated with GnRH $50{\mu}g$ injection by intramuscularly Cyst size was decreased $7.3\times7.2mm$ after 7 days GnRH treatment and disappeared after 14 days GnRH treatment. Also dermatitis by unilateral multiple follicular cysts were recovered after 21 days GnRH treatment.

Two female Yorkshire terrier was referred to Veterinary Medical Teaching Hospital, Seoul National University. In case 1, clinical signs were vomiting, anorexia and weight loss. Cystic intraabdominal mass was identified in radiographic and ultrasonographic examination. In case 2, clinical sign was abdominal distension. In radiographic and ultrasonographic examination, cellular ascites and bilateral intraabdominal masses next to kidneys were observed. Many clusters of glandular epithelial cells with anisocytosis, anisokaryosis, high N:C ratio coarse chromatin and prominent nucleoli were shown in cytologic examination of sanguineous ascites. In all two cases exploratory laparotomy was performed and enlarged ovaries were observed (Rt: 6$\times$5$\times$5 cm and Lt: 3$\times$2$\times$1 cm in case 1 and 3$\times$2$\times$1 cm bilaterally in case 2). After ovariohysterectomy histopathologic examinations were performed. Histopathologically the masses were diagnosed as ovarian adenocarcinoma and ovarian cystadenocarcinoma in case 1 and case 2, respectively. In both dogs no further chemotherapy was carried out. These two dogs had no gross evidence of tumor recurrence at the time of 3 months after tumor resection, but long-term follow-up might be needed.
