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.

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.

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.

유선에서 젖의 생산은 뇌하수체 호르몬인 성장 호르몬과 프롤락틴을 포함한 여러 가지 호르몬의 조절을 받는다. 최근의 연구에 따르면 이 호르몬들 중에서 성장호르몬과 프롤락틴은 유선에서도 그 유전자 전사체가 발견된다 본 연구에서는 유선에서 발현되는 성장호르몬이 유선 특이 발현 유전자의 발현에 미치는 영향을 조사하고자 유선 특이 발현 유전자인 베타-락토글로불린($\beta$-lactoglobulin :BLG)의 프로모터를 모델 시스템으로 하여 소와 사람의 성장 호르몬이 유선의 유전자 발현에 끼치는 영향을 조사하였다. 성장 호르몬은 단독으로 처리하였을 패 베타-락토글로불린 유전자 프로모터 활성을 억제하였다. 그러나 젖 분비 호르몬들인 인슐린, 프롤락틴, 글루코코르티코이드와 함께 처리하였을 때는 농도 의존적으로 BLG 프로모터 활성을 상승시키는 효과를 보였다. 성장 호르몬을 유선 세포내에서 발현시켰을때는 적정농도에서 세포 증식과 유선 프로모터 활성을 크게 증진시켰다. 반면 소의 성장 호르몬 유전자 프로모터는 유선 세포에서 뚜렷한 활성을 나타내지 않았다. 이상의 결과는 유선에서 발현되는 뇌하수체 호르몬들은 조절 누수에 의한 유전자 발현이 아니라 생리적 기능을 가지고 있음을 의미한다. 또 인위적으로 성장호르몬의 발현을 조절하여 적정한 양이 발현되도록 하면 젖의 생산을 증진시킬 수 있다는 가능성도 암시한다.

돼지에 있어서 약 115일간의 임신 기간 중 마지막 40일 동안에 유선 내에서 유액도관(duct), 분비소엽(lobules), 분비낭포(alveoli) 등의 parenchyma 조직이 현저하게 발달하게 되는데, 이는 단백질 호르몬 relaxin과 estrogen의 공동작용에 기인하여 촉진되는 것으로 알려져 있다. 최근에는 면역조직화학적 실험방법을 통해 relaxin hormone이 유선조직 세포(mammary gland parenchyma cells)에 직접적으로 작용하여 lobuloalveolar의 발달을 촉진할 수 있는 가능성을 시사하였다. 즉 Relaxin에 특이적이고 포화 가능한 Relaxin의 결합부위가 lobulo-llveolar 구조 및 유액도관(lactiferous duct)의 상피세포(epithelial cells)뿐만 아니라 혈관세포에서도 존재함을 관찰하였다. 본 연구의 목적은 유선조직 세포에 존재하는 relaxin 결합부위가 기능적으로 활성을 지닌 relaxin 수용체(functional relaxin receptor)인지를 규명하고 동시에 relaxin hormone이 유선조직 세포에 직접적으로 작용하여 lobulo-alveolar의 발달을 촉진하는 지에 대한 직접적인 증거를 제공하는 데 있다. 정상적인 생리주기를 가진 3마리의 생후 7개월 된 잡종재지에 대하여 양쪽 난소를 모두 제거하는 양측난소 절제시술(Bilateral ovariectomy)을 실시하였다.(day 0). 난소 절제시술 후 15일부터(day 15) 29일(day 29)까지 각 개체별로 estradiol benzoate(1 mg/2 ml /Com oil)를 12시간 간격으로 근육주사 하였다. 시술 후 22일째부터(day 22) 순수 정제된 relaxin을 miniature osmotic pump를 통하여 몸의 anterior end로부터 왼쪽부위의 4번째 유선에 일정한 속도(1 ug/hr)로 주입하기 시작하였으며, 동일한 개체의 오른쪽 부위의 4번째 유선에는 동일한 방업으로 생리적 식염수(대조군)을 주입하였다. 난소 절제수술 후 29일째(day 29) 각 개체를 희생하여 젖꼭지의 base로부터 1cm 떨어진 지점에서 osmotic pump의 위치로부터 가까운 parenchyma 조직 시료를 채취하여 약 5-mm cube으로 자른 다음 조직학적 분석을 위한 일반적 조직시료 처리과정을 시행하였다. 조직절편을 Weigert's iron hematoxylin과 함께 염색한 다음 Olympus AH-2 광학현미경을 이용하여 lobulo-alveolar의 발달과 세포외간 섬유사인 collagen의 밀도와 정렬정도를 조사하였다. 생리식염수로 처리된 유선조직에 있어서는 lobulo-alveolar의 발달이 거의 일어나지 못한 반면, relaxin을 처리한 유선조직은 lobulo-alveolar의 현저한 발달을 보였을 뿐만 아니라 분비낭포(alveoli) 내에서는 두드러진 분비물이 존재하였다. 또한 식염수로 처리된 유선조직에서는 비교적 조밀하고 매우 잘 발달된 collagen 섬유사 묶음을 가진 세포의 간 기질의 특징을 보였으나, relaxin 호르몬이 처리된 유선조직에서는 collagen 섬유사가 비교적 분산되어 있고 느슨하며 덜 조밀한 구조적 특징을 나타내었다. 결론적으로, 본 연구의 결과는 유선조직 내의 특이적 relaxin 결합세포가 기능적으로 활성을 지닌 relaxin 수용체를 함유하고 있으며, relaxin hormone이 유선조직 세포에 직접적으로 작용함으로써 lobulo-alveolar의 발달을 촉진함을 보여준다.

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.
