Objectives: To investigate therapeutic mechanisms of Gyejibokryeong-hwan (GJBRH) against gynaecological diseases, articles on biological assay were gathered and analyzed. Methods: The articles were classified as being from domestic or international journals, and by their year of publication. The mechanisms of the biological effects against gynaecological diseases were noted. Results: Of the 14 articles analyzed, 13 were published in China and 1 was from Japan. GJBRH showed therapeutic effect against uterine and mammary gland diseases. Uterine-related diseases such as endometriosis, hysteromyoma, adenomyosis, cancer, and inflammation can be improved by the administration of GJBRH through anti-angiogenesis, anti-inflammation, the modulation of immune cell and immunoglobulin, and the regulation of hormone secretion. GJBRH also reduced mammary hyperplasia by regulating hormone and cytokine release. Conclusions: We speculate that the inhibitory effect against uterine and mammary gland diseases could be related to the therapeutic efficacy of GJBRH in improving gynaecological diseases.

A case of mammary gland adenocarcinoma is reported in a 22-year-old female Mandril (Mandrillus sphinix). The veterinarian noted a fast growing mass, which was inflammed and perforated, involving both mammary gland during the last 4 months. Supplement antibiotic and chemotherpay were unsucessful and the monkey was found dead. On necropsy, both right and left mannary gland were replaced by firm, tan, perforating neoplastic mass.

Effects of anthranilic acid on normal mammary gland growth were examined in SHN/Mei female virgin mice. Anthranilic acid was given to the experimental groups as drinking water at the concentrations of 0.01, 0.02 or 0.04% for 21 days beginning 2-3 months of age. The control group received tap water only. RNA content and RNA/DNA ratio in mammary glands were significantly higher in mice given 0.04% anthranilic acid than in the control, while not mammary DNA content. The results indicate that chronic ingestion of anthranilic acid can induce an enhancement of proliferation and differentiation of mammary cells.

We examined expression patterns of imc-415 gene in mammary gland and in HC11 mammary epithelial cells in culture. mRNA levels of imc-415 gene were higher at pregnancy and involution stages of mouse mammary gland compared with lactation period. Expression of imc-415 gene was induced with serum starvation or treatment with Fas monoclonal antibody in HC11 mammary epithelial cells in culture.

A bitch was presented for investigation of the mass in left 5th mammary gland. The partial mastectomy was performed and submitted for the histopathological diagnosis. The mammary mass was firm and white colored. The cut surface was separated with several lobules and developed vessels. The central area of the mass formed the cavity filled with inflammatory exudates. The dominant component of the tumor was the bundles of spindle-shaped cells. Some tumor cells possessed atypical nuclei and were arranged in a solid nest. Cysts were microscopically composed of hemorrhage, necrosis, and exudates, partially surrounded by tumor cells and granulation tissues. Histopathologically, the mammary mass revealed spindle cell carcinoma. The bitch made a complete recovery following the mastectomy. This case was a rare mammary spindle cell carcinoma in a dog.

Lactogenesis in mammary gland is under the control of various lactogenic hormones including hypophysial growth hormone and prolactin. Recent studies reported that such pituitary lactogenic hormones are also expressed in mammary cells as well as in pituitary. For the purpose to analyze the role of these non-pituitary hormones in mammary cells, $\beta$ -lactoglobulin (BLG) gene promoter was selected as a model system. The growth hormone suppressed BLG promoter activity when it was applied alone on cultured mammary HCll cells. Along with lactogenic hormones such as insulin, prolactin and glucocorticoid, however, it significantly enhanced expression of BLG promoter activity in a dosage- dependent manner. Exogenous expression of the growth hormone gene in cultured mammary cells also strongly promoted cell proliferation and BLG promoter activity. Bovine growth hormone promoter, on the contrary, did not revealed any notable activity. Above results suggest that endogenous expression of the pituitary hormone genes in mammary cells is not a regulation leakage but a physiological control. Moreover, artificial overproduction of the growth hormone in mammary gland may help increase milk production.

Our previous studies demonstrated that relaxin in concert with estrogen promotes development of the mammary parenchyma during the last third of gestation in gilts, and the specific relaxin-binding sites were present in the mammary gland. This study was conducted to determine if relaxin-binding sites in the mammary gland were functional relaxin receptors. Three cycling cross-bred gilts were bilaterally ovariectomized on day 0 of the experiment. Beginning on day 15 and continuing through day 29 post-surgery, the gilt received an im. injection of estradiol benzoate at 12-hr intervals. Beginning on day 22 post-surgery, highly purified porcine relaxin was administered(lug/hr) into the left fourth mammary gland from the anterior end via miniature osmotic pump. Physiological saline was administered to the right fourth mammary gland. The gilt was sacrificed on day 29 post-surgery and histological characteristics of the mammary parenchyma were examined. The mammary glands treated locally with saline showed little, if any, lobulo-alveolar development, whereas the mammary glands treated with relaxin showed not only marked lobulo-alveolar development but also prominent secretions in the alveoli. The saline-treated glands were characterized by relatively dense and highly organized collagen fiber bundles. Whereas, in the relaxin-treated mammary glands, collagen fiber bundles were dispersed and loosely organized. In conclusion, relaxin-binding sites in the mammary gland are functional relaxin receptors and relaxin acts directly on the pig mammary gland to promote development of the alveoli and remodeling of the extracellular matrix.

Thirty lactating Javanese thin-tail ewes (12 ewes had been injected, prior to mating, with 700 IU pregnant mare serum gonadotropin, and 18 ewes with saline as a control) were used to evaluate the effect of superovulation on milk production during lactation and mammary chemical indices at the end of lactation. Thirteen ewes (9 control and 4 superovulated ewes) were fed at low and the other 17 ewes (9 control and 8 superovulated ewes) were fed at high quality ration. Superovulated ewes, either fed at low or high quality ration, had dramatically higher milk yields (57%). At the end of lactation, superovulated ewes had higher mammary dry fat-free tissue, mammary DNA concentration, total mammary DNA and RNA contents than nonsuperovulated ewes. Superovulation did not affect mammary RNA and collagen concentrations, and total collagen content. Ration quality did not significantly increase milk production during lactation and mammary chemical indices at the end of lactation. The observed increase in milk production in the superovulated ewes was probably due to the increased mammary secretory cell number and their synthetic activities during lactation as a result of the increased endogenous hormonal stimulation of mammary growth and development during pregnancy.

Mammary gland tumors are the most common neoplasms occurring in female dogs. The treatments of mammary gland tumors are surgery, chemotherapy, hormonal therapy and radiational therapy, but surgical removal remains widely accepted treatment option for mammary gland tumors. The purpose of this study is to evaluate clinical outcomes of dogs which are performed surgical excision. Medical records were reviewed for dogs(79 cases) with mammary gland tumors treated surgically at Veterinary Medical Teaching Hospital in Seoul National University from 2001 to 2005. While 49 cases(62.0%) were benign, 30 cases(38.0%) were malignant tumors. The mean age of these dogs was 10.4 years old(range $1{\sim}16$ years). The maximal diameter of malignant tumors were various, whereas most of the benign tumors were smaller than 3cm(36 cases, 73.5%). In 12 cases(15.2%), regional lymph nodes were enlarged and lymph nodes of 3 cases had resected surgically. The performed techniques were total mastectomy, regional mastectomy, simple mastectomy, lumpectomy and unilateral mastectomy in order. Twenty-eight cases(35.4%) had postoperative complications consisted of recurrence of tumors, necrosis, dehiscence, delayed healing and edema of limbs. The recurrence rates of benign and malignant mammary gland tumors were 8 cases(16.3%) and 6 cases(20.0%). Metastasis rate was 7 cases(8.9%). Although postoperative complications were no remarkable difference in recurrence rates among surgical techniques in this study, other complications such as edema of limbs, necrosis, dehiscence and delayed healing were remarkable difference as surgical techniques. Therefore, this result suggest that choice of appropriate surgical techniques should be determined according to each patient's physical status and characteristics of tumors.

Mammary analogue secretory carcinoma (MASC) has histologic similarities to not only acinic cell carcinoma but also other low grade cystadenocarcinoma, and has similar features to breast secretory carcinoma. MASC was not described through the existing classification system previously. But, MASC was distinguished from other salivary gland tumors by Skalova et al. in 2010, MASC has ets variant gene 6-neurotrophic tyrosine kinase, receptor, type 3 (ETV6-NTRK3) translocation. So far, there are 4 cases of MASC recognized in the head and neck region in Korea. One of the four is a tumor from the submandibular gland, and the other three are of the parotid gland. In this case report, we report a 40-year-old man with a MASC of the parotid gland, who presented with right infra-auricular mass.
