2.Studies on Fibrinolytic System Behavior in Women with Polycystic Ovary Syndrome.
Korean Journal of Obstetrics and Gynecology 2003;46(8):1481-1485
OBJECTIVE: To evaluate the plasma concentration of plasminogen activator inhibitor 1, main regulator of fibrinolytic system in women with polycystic ovary syndrome and to clarify whether it may be involved in the pathogenesis of chronic anovulation. METHODS: Fibrinolytic system (plasma fibrinogen, plasminogen, plasminogen activator inhibitor 1 concentration) was assayed in women with polycystic ovary syndrome and compared to normal controls. RESULTS: Women with polycystic ovary syndrome had significantly higher plasminogen activator inhibitor 1 and fibrinogen concentration compared to normal controls. CONCLUSION: Women with polycystic ovary syndrome may have an imbalance in the fibrinolytic system that is tilted towards a reduced production of the proteolytic enzyme plasmin. It may result in impaired follicular rupture and anovulation at cellular level in the ovaries.

Clomiphene citrate is the simplest and least expensive from of ovulation induction therapy. In most cases, women who fail to ovulate in response to maximal doses of clomiphene became candidates for treatment with gonadotropins or pulsatile GnRH. Recently, as an alternative to the use of gonadotropins and ovarian surgery, there are some studies of the effectiveness of extended duration clomiphene among the anovulatory women who were resistant to a standard 5-day course of treatment with clomiphene. We have experienced a case of successive ovulation induction and pregnancy with an extended 10-day course of clomiphene in women with clomiphene-resistant anovulatory disorders and reproted with brief reviews of related literatures.

In the context of the new era, paying attention to maternal and child health and advocating prenatal and postnatal care can effectively improve the quality of the birth population. Traditional Chinese medicine has a long history of prenatal and postnatal healthcare with rich content, which is the theoretical basis of modern related services. With the social development and the improvement of people's awareness of prenatal and postnatal healthcare, people have gradually shifted the focus of prenatal and postnatal healthcare to the peri-pregnancy stage at present, namely that couples of childbearing age are guided to prepare for pregnancy under the premise of solving their basic diseases. Infertility is a common and refractory disease for women of childbearing age. Ovulation disorder is one of its common pathological mechanisms. Traditional Chinese medicine believes that kidney deficiency is the main cause and pa-thogenesis of anovulation infertility and blood stasis is an important factor throughout the disease course. In clinical practice, therapies for invigorating kidney and activating blood are safe and reliable to treat anovulatory infertility mainly by adjusting the hypothalamus-pituitary-ovarian axis, improving ovarian function, uterine environment and gamete quality and increasing endometrial volume. Under the guidance of the thought of prenatal and postnatal healthcare, the authors tried to explore the effect of therapies for kidney-tonifying and blood-activating in the treatment of anovulatory infertility in eugenics, with the purpose of providing ideas and basis for subsequent relevant clinical studies and contributing to prenatal and postnatal healthcare services.

OBJECTIVE: Polycystic ovarian syndrome (PCOS) is a heterogenous dysfunctional endocrinologic disorder with unknown etiology, clinically characterized by obesity, chronic anovulation, masculinization and infertility. Recently, the association between polycystic ovarian syndrome and insulin resistance have been brought up and insulin resistance is one of the most important factor related to the development of obesity. However, not all polycystic ovarian syndrome patients are obese, it would give a clue to understanding pathophysiology of obesity and PCOS if insulin resistance could be classified according to the degree of obesity in PCOS. Thus, we performed this prospective study to know the relationship between insulin resistance and obesity in the patients with PCOS. METHODS: Fourty eight polycystic ovary patients were included at Samsung Cheil Hospital from April to October 2002. These patients were grouped according to obeseness. HOMA index was used to evaluate insulin resistance calculated by using fasting blood sugar and serum insulin level. RESULTS: Twenty patients (41%) were classified as obese group, twenty eight patients (59%) had normal body mass index. Increased insulin resistance was observed in the patients with polycystic ovarian syndrome. And it was significantly higher in the obese patients compared to the patients with normal body mass index (6.8+/-2.8 vs. 2.7+/-0.9, t-test, p<0.01). CONCLUSION: For increased insulin resistance, immediate management would be needed in the patients of polycystic ovarian syndrome, especially combined with obesity.

Polycysytic Ovary Syndrome (PCOS) is a common endocrine disorder characterized by chronic anovulation and hyperandrogenism. The etiology of PCOS is complex and incompletely understood. Accumulating data conclude that hyperinsulinemia and hyperandrogenemia may cause hormonal abnormalities that lead to disturbance of ovarian function. Although insulin resistance is not a part of the diagnostic criteria for PCOS, its importance in its pathogenesis can not be ignored. Excess insulin is capable of stimulating steroidogenesis and therefore excessive androgen production occurs from the theca cell system. Recently, the effects of insulin sensitizer in PCOS patients are being reported and they include the improvement of menstrual pattern, improvement in hyperandrogenism, increased response in ovulation induction and prevention of cardiovascular diseases. Understanding the relation of PCOS and insulin resistance will offer an improvement in treatment of PCOS in the future.

Ovulation induction in hypothalamic amenorrhea using gonadotropin- releasing hormone(GnRH) pulse therapy is complicated by widely variant patient responses ranging from anovulation to multiple pregnancy. Route of administration(intravenous vs subcutaneous), pulse therapy, GnRH dose, infusion interval, or hormone preparation may contribute. We evaluated the bioactivity of 4 GnRH preparations(Relisorm,Serono; Lutrelef,Ferring; Factrel,Ayerst; GnRH,Sigma) in a rat anterior cell bioassay. Dispersed rat anterior pituitary cells were placed for 48 hrs at 5x105 cells/well, washed and incubated with GnRH. The GnRH was diluted according to the manufacturer's culture medium(10(-12) to 10(-5)M). GnRH stimulated immunoreactive luteinizing hormone(LH) production was assested in culture medium after 4 hrs by radioimmunoassay(RIA). A linear dose-response relationship was exhibited by all preparations from 10(-10) to 10(-7)M. Msximal LH production was 249+/-24 ng/ml/4hrs(mean+/-SEM) and was not different among the preparations tested(ANOVA, p>0.05). The minimal effective dose of GnRH was 10-10M for all preparations(basa1=27+/-4ng/ml/4hrs:mean+/-SEM). No significant differences were noted for MED, or dose-response slope(p<0.05, ANOVA and slope test for parallelism, respectively). In addition, bioactive LH and immuno and bioactive follicular stimulating hormone(FSH) dose responses were confirmed. We concluded that the principal variability of patient response seen with GnRH pulse therapy cannot be attributed to the bioactivity of these commercial GnRH preparations. But rather, most of the variability is due to the inherent individualism in patient response or other factors of the treatment protocol.

9.Abnormal Uterine Bleeding.
Journal of the Korean Medical Association 2006;49(10):927-936
The average length of menstrual cycle is 28 days, and duration of flow is 4 days, and an average blood loss is 35cc. Abnormal uterine bleeding is defined as bleeding at abnormal or unexpected times or by an excessive flow at the time of expected menses. Any bleeding should be considered abnormal in premenarchal girls and in postmenopausal women. The etiology of abnormal uterine bleeding encompasses a wide range of disorders that can be secondary to pregnancy-related disorders, anatomic changes of the female genital tract, infection, endocrinologic disorders, malignancies, and systemic illnesses. Dysfunctional uterine bleeding (anovulatory or ovulatory) is diagnosed by exclusion of these causes. An appropriate workup is guided by age-related differential diagnoses for abnormal bleeding. Modern diagnostic tools can readily reveal the underlying pathology and allow timely intervention. Most abnormal genital tract bleeding occurs in the form of uterine bleeding, which is one of the most common gynecologic problems that health care providers encounter with, accounting for approximately 19% of office visits and 25% of gynecologic operations. The author will review the categories of abnormal uterine bleeding and the diagnostic tools needed to establish the correct diagnosis and treatment strategy.

Endometrial cancer is a rare condition in women under 40 years of age. However, patients with anovulatory polycystic ovary syndrome are at risk of developing endometrial cancer due to unopposed and prolonged effect of estrogen on the endometrium. Polycystic ovary syndrome (PCOS) is the most common endocrinopathy in women of reproductive age resulting from insulin resistance and the compensatory hyperinsulinemia. This has adverse effects on multiple organ systems and may result in alteration in serum lipids, anovulation, abnormal uterine bleeding and infertility. In addition, PCOS may place the patients at risk for the development of type 2 diabetes, hypertension, endometrial cancer and cardiovascular disease. We report a case of endometrial cancer in a young patient with PCOS with brief review of the literatures.
