Metabolic Regulation

Obstetrics and Gynecology

The elucidation of pathophysiology and physiological mechanism on reproductive medicine, perinatology, and gynecologic oncology, are the purposes of the reproductive medicine and gynecology course. Using the molecular biology techniques, the graduate students are able to master the advanced assay techniques and how to handle the biomaterials for the most suitable preparation of DNA, RNA and proteins to various experiments. In succeeding human FSH and LH receptor gene cloning, we are investigating their downstream signal transduction pathways, and their relation of sex maturation and abnormality.

Research & Education

Research content

In reproductive medicine field, the relation with human FSH receptor and LH receptor abnormality, and the disease, e.g. precocious puberty, are investigated. We are also studying about relation between ovarian response and FSH receptor polymorphisms with human samples. In gynecologic oncology field, the followings are investigated: mutation analyses of some tumor suppressor genes; cloning of disease related genes; ovarian cancer gene therapy. In perinatal medicine field, amnion culture system has been established in our group, and the correlation between adrenomedullin and abnormal pregnancy is investigated.

Business education

The medical school: Reproductive physiology, reproductive endocrinology, physiology of pregnancy and parturition, pathophysiology, diagnoses and therapy of gynecology are lectured. On the basis of the experimental medicine such as endocrinology and pathology, students can understand reproductive physiology and disease state of the woman, etc., and they can reach the accurate diagnosis and treatment.

The graduate school: The graduate students are researching to discover new biologically active substance and elucidate hormonal effect and interaction on hypothalamus-hypophysis-ovary pathway at molecular level. The correlation between hormones and their receptors, and between hormone receptor structure and function are now our main themes. The ovulation mechanism, hormone and cell growth factor in cancer cells, and cytokine and uterine contraction of pregnancy are also studied.

Clinical Activities

In clinical field, the doctors are arranged to three specialist groups; perinatal medicine, gynecologic oncology, and reproductive medicine group. We are bearing in mind to give optimum medical treatment to each patient. In reproductive medicine, the medical level of in vitro fertilization and embryo transfer including the micro-fertilization is reaching top class in Japan. In perinatal medicine, the medical levels of management of gestational diabetes complicated with pregnancy and multiple pregnancy is quite satisfactory. In gynecologic oncology, clinical researches are carried out to minimal invasions which do not hurt the QOL of the patients, while multimodal therapy which appropriately combined operation, chemotherapy and radiotherapy is carried out. The cooperation between radiology, internal medicine, surgery, pediatrics, urology is also close, and medical integration with the high specialty is established.

Citizenship Activities

The extension lectures (adult education university courses) are held every year. Themes taken up until now are puberty, infertility, pregnancy and diseases, uterine cancers, ovarian cancer, and hormones and diseases. The participation of public health nurses, middle and high school teachers, are also frequent, and they contribute to community health. We hold the academic congresses cooperating with Gunma brunch of Japan society of obstetrics and gynecology several times a year. Some special workshops and seminars in the reproductive medicine, osteoporosis and menopause, gynecologic oncology and chemotherapy, and perinatal medicine are also promoted every year. Education lectures are carried out, and the lecturers are invited from another university, not only our staffs. We participate to sex education in high school and medical consultations via Internet.
