Objective: To estimate the efficacy of sequential treatment of bladder endometriosis (BE) of the vesicoureteric junction using transurethral resection (TUR) and hormonal therapy. Design: Case report. Setting: Private multispecialty hospital. Patient: A multiparous woman presented with perimenstrual lower urinary tract symptoms, cyclic chronic pelvic pain, and left loin pain. Intervention[s]: Ultrasonography revealed marked left renal dilatation. Computed tomography confirmed the presence of a bladder mass. A diagnostic cystoscopy revealed compression of the left vesicoureteral junction. Complete TUR BE with release of chocolate material during resection, followed by ureteric double J stent insertion for 3 months, was performed. Histopathology confirmed the diagnosis of BE, followed by adjuvant hormonal therapy (dienogest) for 3 months. Follow-up for about 2 years revealed complete relief of the symptoms without any recurrence. Main Outcome Measure[s]. Success and recurrence rates of sequential TUR and hormonal therapy of BE of the vesicoureteric junction. Result[s]. TUR BE followed by adjuvant hormonal therapy was very effective in eradicating BE of the vesicoureteric junction in a safe manner without recurrence on follow-up for 2 years. Conclusion[s]. BE of the vesicoureteric junction can be properly treated by sequential TUR and hormonal therapy without recurrence over a 2-year follow-up.

Purpose: The purpose of this study was to investigate the levels of knowledge and medication adherence to hormonal therapy (HT) and to identify the factors influencing medication adherence for patients with breast cancer. Methods: Data were collected from 136 patients undergoing adjuvant HT for breast cancer in 3 general hospitals from July 1 to August 14 in 2014 using self-report questionnaires. Data were analyzed using descriptive statistics, independent t-test, ANOVA, $Scheff{\grave{e}}$ test, and multiple regression. Results: The average of knowledge about HT was $5.15{\pm}2.22$ (Max 9), and that of medication adherence was $5.76{\pm}1.65$ (Max 8). Younger age, shorter duration of HT, more active participation in decision making for treatment, positive perception for impacts of HT, and stronger belief in cure were influencing factors on higher adherence level. Age, duration of HT, and perception on the impacts of hormonal therapy, and belief in cure explained 25.2% of the adherence. Conclusion: To improve the treatment adherence to hormonal therapy, patient education and involvement in decision making, and the tailored intervention for the patients with older age, and long treatment period of HT are needed. Additionally, the strategies for diminishing unintentional forgetting is necessary to be developed.

The purpose of this study was to evaluate effects of hormonal treatments on corpus lutea, follicles and development stage of embryos for enhancing the production efficiency of in vivo porcine embryos suitable to introduce fo foreign genes. Hundred and twenty gilts were allocated to 6 experimental group in different combinations of hormones PG 600, PMSG, hCG and altrenogest. When gilts were treated with chorionic gonadotrophin 200 IU and serum gonadotrophin 200 IU(PG 600), altrenogest, serum gonadotrophin (PMSG) 1,000 IU, and chorionic gonadotrophin(hCG) 750 IU (PAPh), the numbers of corpus luteum (30.4) were significantly higher than those of other treatment groups (P<0.05). The number of corpus luteum from ovary in either right (9.1) or left (10.1) side was not significantly changed with hormone treatments. Number of follicles in control was 20.7, which was higher than those of hormonal treatment groups. The average numbers of 1, 2, 4 and 8 cell staged embryos were 8.1, 1.4, 1.6 and 1.0 in control, but the numbers of 1-cell stage in PAPh treatment group was 24.2, which was significantly higher than those of treatment groups (P<0.05). Therefore, these data indicated that hormonal treatment, especially PAPh, enhanced the developments of follicles, corpus lutea and embryos and increased the collection rate of the 1-cell stage embryos to introduce of foreign genes.

Objective: The purpose of this study was to evaluate and compare the effects of metformin and rosiglitazone in overweight or obese women with polycystic ovarian syndrome. Methods: Twenty Six overweight or obese patients with polycystic ovarian syndrome were randomly treated with either metformin (500 mg three times daily, n=13) or rosiglitazone (4 mg once daily, n=13) for 6 months. Hormonal studies were performed before and after treatment. Insulin resistances were calculated by computerized HOMA 2 Calculator v2.2. Results: Testosterone decreased while SHBG increased after 6 months treatment in both metformin and rosiglitazone treatment groups. Fasting glucose decreased after metformin or rosiglitazone treatment. HOMA insulin resistance improved after treatment with either drug. There was no differences in hormonal changes and insulin resistance between 2 treatment groups. Conclusions: This study shows that metformin and rosiglitazone are effective in improving insulin sensitivity and ameliorating hyperandrogenism in overweight/obese polycystic ovarian syndrome women.

Since cancer is one of the leading causes of death worldwide, and there is an urgent need to find better treatment. In recent years remarkable progress has been made towards the understanding of proposed hallmarks of cancer development and treatment. Treatment modalities comprise radiation therapy, surgery, chemotherapy, immunotherapy and hormonal therapy. Currently, the use of chemotherapeutics remains the predominant option for clinical control. However, one of the major problems with successful cancer therapy using chemotherapeutics is that patients often do not respond or eventually develop resistance after initial treatment. This has led to the increased use of anticancer drugs developed from natural resources. The biodiversity of venoms and toxins makes them a unique source from which novel therapeutics may be developed. In this review, the anticancer potential of snake venom is discussed. Some of the included molecules are under clinical trial and may find application for anticancer drug development in the near future.

A on-off study was designed to evaluate the effects of addition of transdermal esrtradiol to tricyclic antidepressants on depression level, vasomotor symptom(hot flush), sexual functions and hormonal status, plasma 5-hydroxyindoleascetic acid(5-HIAA) level in postmenopausal women with depression. Plasma level of estradiol, progesterone, LH, FSH, prolactin and 5-HIAA was measured by Time-resolved fluoroimmunoassay and HPLC(High Performance Liquid Chromatography). To asses their symptoms, the BDI(Beck Depression Inventory) and modified symptom scale, extracted from women's health questionnaire were used. Depression score, sexual function score were decreased by the last 4-weeks of addition of transdermal estradiol to antidepressant treatment, not Significant, but vasomotor symptom (hot flushes) score was decreased significantly(p<0.05) by the last 4-weeks of the given treatment. Thus, during addition of transdermal estradiol to antidepressants treatment, only vasomotor symptom(hot flushes) was improved significantly, but depression level was not changed in postmenopausal women with depression. Plasma FSH, estradiol and prolactin level was not changed in postmenopausal women with depression. Plasma FSH, estradiol and prolactin levels were increased by the last 4-weeks of the treatment. There were not significant correlations between clinical symptoms and plasma hormonal status and 5-HIAA level in baseline. After the last 4-weeks of transdermal estradiol treatment, the change of depression score was correlated significantly with change of serum prolactin and 5-HIAA level and the change of vasomotor symptom score was correlated significantly with the change of plasma prolactin level.

Acetyl-CoA carboxylase (ACC) is the enzyme that controls no devo fatty acid biogynthesis, and this enzyme catalyzes the carboxylation pathway of acetyl-CoA to malonyl-CoA. Acetyl-CoA carboxylase gene expression was regulated by nutritional and hormonal status. The present study was performed to identify the regulation mechanism of ACC gene promoter I. The fragments of ACC promoter I -1.2-kb region wert recombined to pGL3-Basic vector with luciferase as a reporter gene. The primary hepatocytes from the rat were used to investigate the hormonal regulation of ACC promoter I activity. ACC PI (-1.2)/Luc plasmid was trtransferred into primary hepatocytes using lipofectin. Activity of luciferase was increased two-fold by 10-9M, three-fold by 10-8M, 10-6M, 3.5-fold by 10-6M, and 4.5-fold by 10-7M insulin treatment, respectively. In the presence of dexamethasone (1 $\mu$M), the effects of insulin increased about 1.5-fold, showing the additional effects of dexamethasone. Moreover, the activity of luciferase increased with insulin+dexamethasone, insulin+T3, dexamethasone+T3, and dexamethasone+insulin+T3 treatment approximately 6-, 4-, 6.5-, and 10-fold, respectively. Therefore it can be postulated that 1) these hormones coordinately regulate acetyl-CoA caroxylase gene expression via regulation of promoter activity, 2) the -1.2-kb region of ACC promoter I may have the response element sequences for insulin, dexamethasone, and T3.

Hormonal induction of sex reversal was examined by using sex steroid hormones in serranid fish, Epinephelus septemfasciatus. Young fish were collected from the coastal area of Cheju Island, and reared for 2 years before fish were used for the experiments. Without any hormonal treatment, gonads of fish ($1,000\~2,800$ g in body weight) were occupied by oocytes of the perinucleolus stage and bundles of protogonial cells in the area of germinal epithelium. When the induction of sex reversal was attempted by daily oral administration of $17\alpha$-methyltestosterone (0.5 mg/kg fish) for 90 days, active spermatogenesis was induced, and spermatogonia and spermatocytes and spermatids were appeared in all gonads we examined. However, after daily, oral treatment of $17\beta$-estradiol (0.5 mg/kg fish) to. 50 days with the following injection of human chorionic gonadotrophin ($1,000\~1,500$ IU/kg fish) mature oocytes were not induced in fish gonad.

To investigate changes of estrus signs and genital organs in the bitch by hormonal induction of estrus, fourteen bitches of nulliparous and multiparous(2nd-5th) were grouped into diestrus and anestrus according to their estrus cycle. The hormonal treatments were divided into four groups: group A($PGF_2{\alpha}+PMSG+hCG$) and group B(PMSG+hCG) in diestrus bitches and group C(GnRH+FSH+hCG) and group D(PMSG+hCG) in anestrus bitches. The external signs of proestrus and estrus as well as the vaginal smear findings and natural breeding as estrus detection were investigated in all the experimental groups. Also, genital organs were examined at two months after the hormone treatment. The bitches in anestrus showed 100% of male attraction, vaginal bleeding and vulvar swelling as proestrus signs after the hormonal treatment for estrus induction and they showed higher numerical value of signs than the bitches in diestrus. The group A showed the lowest value in proestrous signs of all the groups. The bitches in anestrus treated with GnRH+FSH showed 100% of positive estrus by vaginal smear findings and 75% of natural breeding as estrus detection index and these values were the highest of all the groups. Pregnancy was recognized in only group C and the conception rate was 7.14% in al the experimental animals. Of the side effects after the hormone treatment, external findings of continous male attraction, continous external swelling and purulent exudate were recognized in all the experimental groups and the bitches in diestrus showed higher value of the findings than the bitches in anestrus. Of the changes of genital organs after the hormone treatment, hypertrophy of uterine horn, sanguineous exudate and purulent exudate as uterine findings were recognized in all the groups and these findings were shown more in the bitches in diestrus than in those in anestrus. These results indicated that group C showed the highest value of all the experimental groups in external signs of estrus and estrus detection and also pregnancy was recognized only in that group, consequently, that the hormonal treatment of group C would be the most effective for estrus induction, and also indicated that bitches in anestrus were more suitable than bitches in diestrus for the induction of estrus. In addition, side effects in external genital organs and uteri after hormone treatment were shown more in the bitches in diestrus than in those in anestrus, indicating that bitches in anestrus would be of choice for estrus induction.

Here, we evaluated the mode of programmed cell death during porcine oocyte maturation by comparing the two major pathways associated with programmed cell death, apoptosis (type I), and autophagy (type II). We investigated the expression and localization of major genes involved in autophagy and apoptosis at mRNA and protein levels. Furthermore, the effect of hormonal stimulation on autophagy and apoptosis was analyzed. We found that the activity of autophagy-associated genes was increased in the cumulus-oocyte complexes (COCs) following follicle-stimulating hormone (FSH) treatment, while the addition of luteinizing hormone (LH) reversed this effect. The expression of proteins associated with autophagy was the highest in FSH-treated COCs. On the other hand, caspase-3 protein level was maximum in COCs cultured with LH. The treatment with rapamycin resulted in the effect similar to that observed with FSH treatment and increased autophagy activity. Thus, hormonal stimulation of pig oocytes resulted in distinct patterns of maturation. The high-quality oocytes majorly relied on the type II pathway (autophagy), while the type I pathway (apoptosis) was more prominent among poor-quality oocytes. Further investigation of this distinction may allow the development of techniques to produce high-quality oocytes in porcine in vitro fertilization.
