Te is likely to have direct and indirect inhibitory effects on human osteoclast formation and bone resorption, whereas the effect of E2 on osteoclast precursors and osteoclasts seems to be mediated by osteoblastic cells. Inhibitory effect of E2 is associated with the stimulated secretion of OPG by osteoblast-derived osteosarcoma cells. Mechanism of action of E2 and Te is mediated by ER and AR, respectively.

To develop an improved model of human prostate cancer, 16-wk-old Wistar rats were treated orally for 18 days with the antiandrogen, flutamide (50 mg/kg body weight [BW]/day), followed by 3 days of s.c. testosterone (100 mg/kg BW). There were the only treatments the control animals received (Group 1, n = 10). On the day after the third testosterone injection, N-methyl-N-nitorsourea (MNU) was administered via the tail vein at a dose of 50 mg/kg BW (Groups 2, n = 40 and 3, n = 20); in some rats, a second dose was delivered by the same route 22 wk later (Group 3). A smaller dose of MNU (15 mg/kg BW) was administered intraprostatically (Group 4, n = 20) to a fourth group. In Groups 2, 3, and 4, silastic capsules containing testosterone were implanted s.c. approximately every 6 wk beginning 1 wk post-MNU. Accessory sex gland tumors arose in MNU-treated rats in Group 2 (12/40, 30%). Group 3 (8/20, 40%), and Group 4 (8/20, 40%); 90% were macroscopic (25/28). There were no neoplasms in these organs in the control rats (Group 1, 0/10). These accessory sex gland neoplasms were adenocarcinomas or undifferentiated carcinomas which appeared to be derived from the prostate based on location and histological characteristics, although the size and spread of some of the tumors precluded definitive localization of the tissue of origin. The incidence of these neoplasms was similar in rats given a single dose of MNU intraprostatically or two doses of MNU i.v., but the animals treated intraprostatically maintained higher body weights and developed fewer extraneous tumors. The average (+/- SD) latent period for clinical or postmortem detection of prostate neoplasia after MNU was shortest in the rats given two i.v. doses (39 +/- 3 wk) compared with the single i.v. dose (45 +/- 6 wk) or an intraprostatic dose (56 +/- 7 wk). In 57% of the cases (16/28), the prostate tumors metastasized to distant sites. An activating point mutation was detected in codon 12 of the Ki-ras oncogene in the MNU-induced primary prostate tumors (8/10 examined), and metastases arising from these prostate tumors (2/3) but was absent in normal prostate tissue (0/6). This study demonstrates that two systemic doses of MNU increase the incidence and decrease the latency of prostate neoplasms compared with a single dose, and that a single dose of MNU injected intraprostatically induces prostate adenocarcinoma without many of the other tumors and weight loss typically found after i.v. administration.

The growth of pancreatic adenocarcinoma may be under the control of the sex steroid hormone testosterone, besides other unknown stimuli. This premise was based on the discovery of androgen receptors, together with the enzymes aromatase and 5alpha-reductase, which use testosterone as a substrate, in malignant tissue. The additional support of low circulating serum testosterone and its stimulatory role in an animal model using human tumour xenografts further enhance this suggestion. Confirmatory evidence has now come from a double-blind, placebo-controlled trial in patients with pancreatic cancer in which flutamide, the pure androgen receptor blocker, doubled survival duration over control patients. Flutamide was administered in a dosage of 250mg 3 times daily. Support for this finding has recently been presented at a meeting of the Pancreatic Society of Great Britain. It is now important for further confirmatory studies to be carried out and to use flutamide in combination with other current adjuvant therapies in patients with pancreatic cancer.

Using two different databases: MEDLINE and IDIS (Iowa Drug Information Service), we searched for published cases of liver injury induced by antiandrogens. Analysis was made of the type of hepatotoxicity, therapeutic indication, other pharmacological treatments and evolution. Mean values of latency and recovery periods of the adverse reactions and liver function tests were also evaluated.

Epithelial cells cultured from prostatic acini do not demonstrate significant (P > 0.05) growth response to the testosterone metabolite dihydrotestosterone (DHT) at concentrations of 0.001-10.0 nM. In addition, the nonsteroidal antiandrogen hydroxyflutamide (HO-F) does not influence primary epithelial cell proliferation in this concentration range.

The definitions used for refractory disease ranged from none, to "progression", to "unsuccessful second medical or surgical castration. "None of the trials included a definition for hormone-refractory disease based on objective criteria. Details were lacking on most trials with respect to the response to and specific types of hormonal therapies. Furthermore, few trials controlled for the potential contribution of the "flutamide withdrawal syndrome" on outcome.

Classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency is characterized by a defect in cortisol and aldosterone secretion and adrenal hyperandrogenism. Current treatment is to provide adequate glucocorticoid and mineralocorticoid substitution to prevent adrenal crises and to suppress excess adrenal androgen secretion. Satisfactory adrenocortical suppression often requires supraphysiological doses of hydrocortisone, which may produce an unacceptable degree of hypercortisolism. A new four-drug treatment regimen of flutamide, testolactone, reduced hydrocortisone dose, and 9alpha-fludrocortisone has been shown to achieve normal growth and development after 2 yr of therapy and may, therefore, represent a potential alternative approach to the treatment of children with classic congenital adrenal hyperplasia. We investigated the effect of flutamide and testolactone, and flutamide alone, on cortisol clearance by performing clearance studies twice in 13 children (6 males and 7 females; age range, 7.0-14.5 yr) with classic 21-hydroxylase deficiency. All studies were conducted at least 3 months after institution of the four-drug treatment regimen. In eight patients (group 1), the first cortisol clearance study was performed on the four-drug regimen, and the second study was performed after a 48-h washout period off flutamide and testolactone. In five patients (group 2), the first study was conducted 1 wk after discontinuation of testolactone and while patients were receiving flutamide, hydrocortisone and 9alpha-fludrocortisone, and the second study was performed after a 48-h washout period off flutamide. Oral hydrocortisone was held on the day of the clearance studies, and all patients received a continuous infusion of hydrocortisone (0.6 mg/m(2).h) from 1800 h to 0200 h, with cortisol concentrations measured once hourly. In addition, an in vitro study was conducted to exclude the possibility of an analytical interference of flutamide, 2-hydroxyflutamide, and testolactone with the serum cortisol immunoassay. Total body cortisol clearance was significantly lower during treatment with the four-drug regimen than during treatment with hydrocortisone and 9alpha-fludrocortisone (153.5 +/- 26.8 vs.355.4 +/- 65.8 ml/min; P = 0.001). Similar results were obtained comparing flutamide, hydrocortisone, and 9alpha-fludrocortisone therapy to hydrocortisone and 9alpha-fludrocortisone therapy (155.8 +/- 26.5 vs. 281.8 +/- 96.2 ml/min; P = 0.037). The in vitro study indicated that an interference with the serum cortisol immunoassay was unlikely. These findings indicate that the addition of flutamide and testolactone to the treatment regimen of hydrocortisone and 9alpha-fludrocortisone decreases cortisol clearance in patients with classic 21-hydroxylase deficiency, and this effect seems to be due to flutamide. Glucocorticoid replacement doses should be reduced when flutamide is added to the treatment regimen of patients receiving hydrocortisone.

Nandrolone, an anabolic androgenic steroid, reduced delta opioid receptor (DOR) mRNA and the number of DOR binding sites in two neuronal hybrid cell lines: NG 108-15 and the GT1-1 cells. Both cell lines express DOR but only GT1-1 cells express androgen receptors (AR). DOR mRNA levels were maximally decreased by approximately 45% in NG 108-15 cells and by approximately 38% in GT1-1 cells exposed for 24 h to 10(-6) M nandrolone. This action was partly due to a decrease in the rate of transcription of DOR mRNA and was not blocked by the androgen antagonist flutamide. Flutamide antagonized the repression of AR mRNA induced by nandrolone. The synthetic glucocorticoid dexamethasone (10(-6) M) did not modify DOR steady-state transcripts in either cell line. These results suggest that nandrolone presumably regulate DOR mRNA levels through mechanisms independent of the androgen and glucocorticoid receptors.

The pharmacokinetics of FLT-HPBetaCyD, FLT-suspension (FLT-SUSP), and FLT-solution (FLT-COSOLV) were compared after oral (p.o.) and intravenous (i.v.) administration, respectively. In a non-crossover design, male Sprague-Dawley rats received each formulation as a single oral dose [15 mg (54 micro mol) FLT/kg] by oral gavage, or single i.v. dose [1.6 mg (5.8 micro mol) FLT/kg] via an indwelling jugular vein catheter. FLT and its metabolite, FLT-2-OH, were determined in plasma and urine aliquots by an HPLC method.

In conventional rodent toxicity studies the characterization of the adverse effects of a chemical relies primarily on gravimetric, and histopathological data. The aim of this study was to evaluate if the use of two-dimensional gel electrophoresis could generate protein accumulation profiles, which were in accordance with conventional toxicological findings by investigating a model antiandrogen, flutamide (FM), whose toxic effects, as measured using standard approaches, are well characterized. Male Sprague-Dawley rats were orally exposed to FM (0, 6, 30, and 150 mg/kg/day) for 28 days. The expected inhibition of androgen-dependent tissue stimulation, increased luteinizing hormone and testosterone plasma levels, and Leydig cell hyperplasia were observed. Changes in testicular protein accumulation profiles were evaluated in rats exposed to 150 mg/kg/day FM. Several proteins involved in steroidogenesis (e.g., StAR, ApoE, Hmgcs1, Idi1), cell cycle, and cancer (e.g., Ddx1, Hspd1) were modulated by FM, and these data provided molecular evidence for the hormonal and testicular histopathology changes recorded. Changes in proteins associated with spermatogenesis were also recorded, and these are discussed within the context of the testicular phenotype observed following FM treatment (i.e., normal spermatogenesis but Leydig cell hyperplasia). Overall, our data indicate that the combination of conventional toxicology measurements with omic observations has the potential to improve our global understanding of the toxicity of a compound.

We present a novel application of the heteronuclear statistical total correlation spectroscopy (HET-STOCSY) approach utilizing statistical correlation between one-dimensional 19F/1H NMR spectroscopic data sets collected in parallel to study drug metabolism. Parallel one-dimensional (1D) 800 MHz 1H and 753 MHz 19F{1H} spectra (n = 21) were obtained on urine samples collected from volunteers (n = 6) at various intervals up to 24 h after oral dosing with 500 mg of flucloxacillin. A variety of statistical relationships between and within the spectroscopic datasets were explored without significant loss of the typically high 1D spectral resolution, generating 1H-1H STOCSY plots, and novel 19F-1H HET-STOCSY, 19F-19F STOCSY, and 19F-edited 1H-1H STOCSY (X-STOCSY) spectroscopic maps, with a resolution of approximately 0.8 Hz/pt for both nuclei. The efficient statistical editing provided by these methods readily allowed the collection of drug metabolic data and assisted structure elucidation. This approach is of general applicability for studying the metabolism of other fluorine-containing drugs, including important anticancer agents such as 5-fluorouracil and flutamide, and is extendable to any drug metabolism study where there is a spin-active X-nucleus (e.g., 13C, 15N, 31P) label present.

A total of 102 subjects were analyzed in this study, 34 subjects were allotted in each group. The prevalence of IR was statistically different between three groups (P-value = 0.001). After a 6-month course, metformin showed larger reduction in fasting blood sugar (FBS) level (P-value < 0.001). However, except for metformin, two other treatments reduced C-reactive protein (CRP) level significantly (both P-values < 0.001). The level of triglycerides (TGs) decreased considerably in all groups (all P-values < 0.001). Both metformin and simvastatin decreased BMI significantly (both P-values < 0.001). None of the treatments changed high-density lipoprotein (HDL) level (all P-values > 0.05).

Administration of the narcotic antagonist naloxone results in an elevation of serum luteinizing hormone (LH) levels in 10-day-old female, but not male, rats. Previous studies from this laboratory indicated a role for neonatal gonadal steroids in the development of this sex-specific response. In this study, the estrogen receptor antagonist OH-Tamoxifen or the androgen-receptor antagonist flutamide were injected on Days 1 or 9 of life, and the LH responses of male and female pups to naloxone were assessed on Day 10. Flutamide did not produce a response different from that seen in vehicle-treated pups, discounting a role for androgen receptors. OH-Tamoxifen on Day 9 caused an increase in basal levels of LH; neither sex showed a response to naloxone. However, OH-Tamoxifen treatment of 1-day-old males resulted in an enhanced release of LH upon challenge with naloxone on Day 10 of life; similar treatment of 1-day-old females resulted in a normal female-type response to the opioid antagonist. These results show that blockade of estrogen receptors in males during the "critical period" of sexual differentiation results in a female phenotypic response to naloxone. Therefore, estrogen receptors play a critical role in the sexual differentiation of the LH response to naloxone in neonatal male rats.

Although follicle-stimulating hormone (FSH) and estrogens are known to be the main physiological stimuli for the development of the ovarian follicle in mammals, their growth-promoting activity has not been clearly established "in vitro". Furthermore, experimental evidence indicates that FSH and estradiol can independently inhibit granulosa cell proliferation. The present study was aimed at examining the effect of sex steroids in combination with FSH, on DNA synthesis in rat granulosa cells cultured in completely defined medium. Estradiol and FSH, when added separately, produced a significant inhibition of [3H] thymidine incorporation. In contrast, a combination of a low dose of FSH (20 ng/ml) with estradiol (100 ng/ml) produced a shift in the period of maximal DNA synthesis from 96 to 48 h after plating. Dose response studies showed that estradiol effects were produced at physiological intraovarian concentrations (1-100 ng/ml), whereas the effects of FSH were biphasic, with high doses (200 ng/ml) being inhibitory. A similar biphasic dose response curve was observed with increasing concentrations of a cAMP derivative in the presence of maximally effective doses of either an aromatizable steroid (androstenedione), insulin or insulin-like growth factor I. Non-aromatizable androgens (5alpha-dihydrotestosterone, 5alpha-androstane 3alpha-17beta diol and androsterone) showed a potency comparable to that of estradiol. The effect of 5alpha-dihydrotestosterone was completely blocked by a specific antiandrogen (hydroxy-flutamide), indicating that it was mediated by the androgen receptor. The effects of estradiol and androgens were not additive. The interaction between estradiol and FSH was further amplified in the presence of a maximally effective dose of insulin. Data presented herein indicate that both estrogens and androgens are able to elicit a mitogenic response in purified granulosa cells, cultured in a completely defined medium, provided the cells are stimulated by a physiological dose of FSH. These results suggest that, during follicular development, the stimulus for granulosa cell proliferation is given by the concerted action of steroid and peptide hormones acting through different signalling pathways.

Using dimethylbenz(a)anthracene (DMBA)-induced mammary tumors in the rat as model, comparison was made of the effect of treatment for 20 days with the aromatase inhibitor 4-hydroxyandrostenedione (4-OH-A) (7.5 mg, twice daily) or the antiandrogen flutamide (5 mg, twice daily) on tumor growth as well as on plasma and tumor content of estrogens, androgens, and their precursors and metabolites. Tumor number and size were markedly decreased following treatment with either drug, the effect of treatment being more important on size than number, and on new tumors which developed during treatment than on tumors already present at start of treatment. Treatment with the aromatase inhibitor 4-OH-A caused a parallel decrease in plasma and tumor levels of pregnenolone (Preg), progesterone (P), and 17-OH P, while there was a marked increase in dehydroepiandrosterone (DHEA), androst-5-ene-3 beta,17 beta-diol (delta 5-diol), androstenedione (delta 4-dione), testosterone (T), androstane-3 alpha, 17 beta-diol (3 alpha-diol), and androstane-3 beta,17 beta-diol (3 beta-diol), with no significant change in dihydrotestosterone (DHT) and 17 beta-estradiol levels. The marked increase in tissue T content coupled to a decrease in P levels could well contribute to the inhibition of tumor growth induced by 4-OH-A. Flutamide, on the other hand, caused a marked fall in plasma and tissue levels of Preg, 17-OH Preg, P, and 17-OH P, with no significant change in the concentration of the other steroids, thus suggesting a possible role of the fall in tissue P levels in the inhibition of tumor growth. Since both drugs are potent inhibitors of DMBA-induced tumor growth in intact animals, better knowledge of their mechanism of action should add to our understanding of the multiple endocrine factors controlling the growth of these tumors.

We examined whether androgen receptors in the medial preoptic area (MPOA) and lateral septum (LS) are required for the expression of copulation and sexual motivation. Castrated males received testosterone-filled silastic capsules to restore behavior, and were implanted with the antiandrogen hydroxyflutamide (OHF) or blank cannulae. One group was implanted in either the anteroventral MPOA or LS (ANT group). Another group was implanted in the posterodorsal MPOA or LS (POST group). Copulation was tested on days 2, 6, 10, and 14 of OHF exposure; partner preference, a measure of sexual motivation, was tested on day 15. The results showed that sexual behavior was significantly suppressed by OHF in the MPOA of the ANT group, but not the POST group. However, sexual motivation was significantly reduced by OHF in the MPOA of the POST group, but not the ANT group. In the LS, OHF had no effect on sexual behavior and partner preference regardless of implant site. The data suggest site specificity within the MPOA for androgen receptor activation of male reproductive behaviors.

Based on an internal protocol, 14 patients (42%) did not receive AD, while 19 patients (58%) had undergone neoadjuvant and concomitant AD. The median duration of AD before plCT ranged from 0.2 to 6 months (median: 2.9 months). Although individual data were highly variable, compared to plCT volume, mean prostate gland volume change at the end of 3DCRT was similar for patients receiving (-7.3%) or not (-7%) androgen deprivation (P=0.77). However, within the group of patients treated with hormones, patients starting AD within 3 months from plCT had a significantly larger reduction in prostate volume (-14.2%) than patients with longer NAD duration (-1.1%, P=0.03). At tmtCT, on average, patients undergoing 3DCRT within 3 months from AD start showed an increase of the amount of rectum receiving 40-75 Gy compared to plCT values. At 40 Gy (V40) the mean difference between tmtCT and plCT was +7.5%. In the other two groups, average variations of V40-70 were within +/-2% of plCT values. However, these differences are not significant.

Treatment choices for metastatic prostate cancer are complex and can involve men balancing survival versus quality of life. The present study aims to elicit patient preferences with respect to the attributes of treatments for metastatic prostate cancer through a discrete choice experiment (DCE) questionnaire. Men with buy eulexin recently diagnosed localized prostate cancer were asked to envisage that they had metastatic disease when completing a survey. As expected, men with prostate cancer placed considerable importance on gains in survival; however, avoiding side effects of treatment was also clearly important. Survival gains should be considered alongside side effects when discussing treatment options in metastatic disease.

Although androgens are reported to affect stroke outcomes by altering ischemic tissue damage, their effect on post-injury repair is unknown. Since neurogenesis has recently been recognized as contributing to stroke outcomes, we investigated the role of androgens on stroke-induced neurogenesis. Adult male mice were subjected to transient middle cerebral artery occlusion (MCAO) and neurogenesis was examined 1 week later by quantifying BrdU/doublecortin-positive and BrdU/NeuN-positive neurons in brain germinal regions as well as the injured striatum. To elucidate the role of endogenous androgens, post-MCAO neurogenesis was examined in gonadally intact males, intact males implanted with the androgen receptor antagonist flutamide, and surgically castrated males. Surgical castration or pharmacologic androgen receptor blockade had no effects on post-ischemic neurogenesis, except that continuous androgen receptor blockade unexpectedly suppressed maturation of newborn neurons (BrdU/NeuN-positive cells) in the dentate gyrus. Post-MCAO neurogenesis was also examined in surgically buy eulexin castrated mice treated with continuous release implants containing testosterone or dihydrotestosterone (DHT). Testosterone and DHT robustly inhibited post-ischemic neurogenesis in the dentate gyrus, and the more potent androgen DHT virtually abolished the presence of immature newborn neurons (BrdU/doublecortin-positive cells) in the injured striatum. Our data suggest that endogenous androgens do not alter post-stroke neurogenesis quantitatively, but the presence of supra-physiological androgen stimulation profoundly suppresses early neurogenesis in germinal brain areas and reduces cellular repair in injured tissue after cerebral ischemia. These results advance the understanding of the role that androgens play in stroke outcomes.

1. Myotubes cultured from adult male Xenopus laevis laryngeal muscle have been found to express androgen receptors. 2. Using patch-clamp techniques, it was found that 5 alpha-dihydrotestosterone (5 alpha-DHT) can act directly at membranes of these myotubes to alter the kinetic properties of acetylcholine- (ACh) activated single channels. 3. When the culture medium contains 5 alpha-DHT for greater than 6 days, the androgen acts through its receptors to markedly increase ACh-activated, single-channel conductances and alter single-channel kinetics. These effects do not occur if the antiandrogen, flutamide, which prevents the androgen from combining with its receptor, is added to the medium before the addition of the 5 alpha-DHT. These effects also do not occur in myotubes cultured from quadriceps femoris muscles that have much lower levels of specific buy eulexin androgen receptor. 4. When alpha-bungarotoxin (alpha-BTX) is added to the medium for 3 h before recording, no ACh channels can be recorded from myotubes in control medium within 5 h after washout of the alpha-BTX. However, when the culture medium contains 5 alpha-DHT for greater than or equal to 6 days, ACh channels can be recorded within 8 min of the washout of the alpha-BTX. 5. The results suggest that 5 alpha-DHT may act to alter the properties of ACh-activated ion channels at multiple sites in excitable cells.

A short-term reproduction assay with the fathead minnow (Pimephales promelas) has been developed to buy eulexin detect chemicals with the potential to disrupt reproductive endocrine function controlled by estrogen- and androgen-mediated pathways. The objective of this study was to use the assay to characterize responses of fathead minnow reproductive endocrinology and physiology to the mammalian antiandrogen, flutamide. Male and female fish were exposed to nominal (target) concentrations of 50 and 500 microg flutamide/l for 21-days, following which plasma steroid and vitellogenin concentrations were determined and gonadal morphology assessed. Fecundity of the fish was significantly reduced by exposure to a measured test concentration of 651 microg flutamide/l. In addition, embryo hatch was significantly reduced at this concentration. Qualitative histological assessment of ovaries from females exposed to flutamide indicated a decrease in mature oocytes and an increase in atretic follicles. Testes of males exposed to flutamide exhibited spermatocyte degeneration and necrosis. Concentration-dependent increases in plasma testosterone and vitellogenin concentrations were observed in the females. Flutamide also altered reproductive endocrinology of male fathead minnows. Males exposed to 651 microg flutamide/l exhibited elevated concentrations of beta-estradiol and vitellogenin. In summary, the results of this study with the fathead minnow demonstrate that flutamide affects reproductive endocrine function in fish and that the type of hormonal pattern and histopathology effects observed are consistent with an antiandrogenic mode-of-action. Consequently, our findings suggest that the 21-day reproduction assay utilizing fathead minnows is a sensitive short-term screening method for the detection of endocrine-disrupting chemicals, including antiandrogens.

Since the mid-forties androgen deprivation is regarded the standard treatment of incurable prostate cancer. Antiandrogens can be given either as monotherapy or in combination with bilateral orchidectomy or gonadotropin-releasing-hormone analoga. Recently reports buy eulexin have been published that withdrawal of antiandrogens in patients with hormone-resistant prostate cancer caused reduction of PSA and clinical improvement. Thus, in patients who progress under maximal androgen blockade or antiandrogen-monotherapy the antiandrogen should first be withdrawn and-in case of monotherapy-be replaced by GnRH-analoga. In approximately 30-50% of the cases a reduction of serum-PSA can be expected lasting for approx. 6 months. In some patients an improvement of symptoms and objective remission is observed.

The effects of sodium-4-[2-(2,3-dimethyl-4-[1-(4-isobutylphenyl) ethoxy]benzolamino)phenoxy]butyrate (ONO-3805), newly developed as a non-steroidal 5 alpha-reductase inhibitor, on rat accessory sex organs was compared with chlormadinone acetate (CMA) and non-steroidal antiandrogen, flutamide (FLU). ONO-3805 demonstrated excellent antiandrogenic activity which buy eulexin was similar to that of CMA in reducing the accessory sex organ weight. Moreover this agent did not show any significant effects on the serum testosterone level, but CMA and FLU changed it significantly. We previously reported the androgenic activity of antiandrogen (CMA, FLU, AA560, cyproterone acetate, medroxy progesterone, estrogen), but ONO-3805 is free of androgenic activity.

Conventional imaging demonstrated innumerable lesions in two patients and 43 lesions in the remaining 17 patients with advanced prostate cancer. FDHT-PET was positive in 12 of 19 patients (sensitivity of 63%), including the two patients with innumerable lesions. FDHT-PET detected 24 of 28 known lesions (86%) in the remaining ten patients. In addition, FDHT-PET detected 17 unsuspected lesions in five of these ten patients. All 12 patients with positive FDHT-PET underwent a repeat PET study after receiving flutamide for 1 day (250 mg t.i.d.). In all of these patients, there was a buy eulexin decrease in tumor FDHT uptake after flutamide; the mean (+/- standard deviation) SUV and T/M decreased from 7.0+/-4.7 and 6.9+/-3.9, respectively, to 3.0+/-1.5 and 3.0+/-1.6, respectively (p=0.002). The mean PSA in patients with positive FDHT-PET was significantly higher than that in patients with negative FDHT-PET (p=0.006).

The role of androgens in the production of 20-hydroxyeicosatetraenoic acid (20-HETE) was determined in the kidney of spontaneously hypertensive rats (SHR) and Wistar-Kyoto rats (WKY). The renal production of 20-HETE and blood pressure were higher in males than in females at 9 weeks of buy eulexin age. The renal production of 20-HETE was significantly greater in male SHR than in male WKY, whereas it was significantly lower in female SHR than in female WKY. The differences in the renal production of 20-HETE were consistent with the cytochrome P-450 4A protein levels. Plasma free-testosterone levels in male SHR were twice as high as those in male WKY. Castration and treatment with the androgen receptor antagonist, flutamide, reduced blood pressure, the renal production of 20-HETE, and P-450 4A protein levels in both strains. The renal production of 20-HETE was significantly lower in castrated SHR than in castrated WKY. These results indicate that the renal production of 20-HETE and the expression of P-450 4A have gender and strain-differences, and high levels of plasma androgens induce the expression of P-450 4A and the production of 20-HETE in the kidney of male SHR. The androgen-induced production of 20-HETE may be associated with hypertension in male SHR.

A total of 80 advanced prostate cancer patients with bladder outlet obstruction were treated by transurethral electrovaporization of the prostate (TVP), plus castration and antiandrogen therapy. Preoperative individualized preparation was performed for each patient. International Zofran Normal Dose prostatic symptom score (IPSS), maximum flow rate of urine (Q(max)), prostatic-special antigen (PSA), and ultrasonography were measured before and 3 months after operation.

The median follow-up period was 9.1 years. The 10-year rate of overall survival was 62% among patients receiving radiotherapy plus short-term ADT (the combined-therapy group), as compared with 57% among patients receiving radiotherapy alone (hazard ratio for death with radiotherapy alone, 1.17; P=0.03). The addition of short-term ADT was associated with a decrease in the 10-year disease-specific mortality from 8% to 4% (hazard ratio for radiotherapy alone, 1.87; P=0.001 Lopid Tablets 600 ). Biochemical failure, distant metastases, and the rate of positive findings on repeat prostate biopsy at 2 years were significantly improved with radiotherapy plus short-term ADT. Acute and late radiation-induced toxic effects were similar in the two groups. The incidence of grade 3 or higher hormone-related toxic effects was less than 5%. Reanalysis according to risk showed reductions in overall and disease-specific mortality primarily among intermediate-risk patients, with no significant reductions among low-risk patients.

The mean follow-up was 13.5 months (ranging 6 to approximately 30). Before and after the treatment, the prostate volume, prostate specific antigen (PSA), international prostate symptom score (IPSS) and maximal flow rate (Qmax) of the patients were (36.4 +/- 16.2) ml and (20.6 +/- 11.8) ml (P < 0.05), (32.2 +/- 10.4) ng/ml and (2.4 +/- 0.8) ng/ml (P < 0.01), 20. 5 +/- 6.5 and 13.6 +/- 7.5 (P < 0.05), (10 Stromectol Pediatric Dosage .6 +/- 6.3) ml/s and (14.2 +/- 4.6) ml/s (P < 0.05), respectively. Mild hematuria and pain were noted in 5 and 8 patients respectively, and 1 patient underwent internal urethrotomy with a cold knife because of urethral stricture. er, with minimal complications.

The dose-dependent effects of daily estrogen (estradiol, ethinyl estradiol, diethylstilbestrol) administration on the activities of three hepatic androgen-dependent microsomal enzymes (3 alpha- and 3 beta-hydroxysteroid dehydrogenase and 5 alpha-reductase) in male rats were examined. Antiestrogens were then tested for their ability to block the feminizing action of 10 micrograms estradiol/day on these enzyme activities; nafoxidine and monohydroxytamoxifen were the most effective. The prevention of 5 alpha-dihydrotestosterone-induced changes in these activities in ovariectomized females was investigated. All three estrogens at a dose of 1 microgram blocked the action of 500 micrograms androgen. A similar androgenic blockade was achieved by daily administration of 5 mg flutamide or constant infusion of human GH (5 micrograms/h). Simultaneous administration of 200 micrograms monohydroxytamoxifen prevented the androgen-antagonizing action of estrogens, but not of flutamide nor of GH. Large doses of estrogens have the same repressive effect as androgens on 5 alpha-reductase activity in female castrates. Using the diethylstilbestrol-treated rat as a model, it is demonstrated that this effect can be prevented by antiestrogen, but not by GH. It is concluded that androgens and low doses of estrogens affect these enzyme Bactroban Ointment Dosage activities by acting at different levels of central regulation, whereas large doses of estrogens act directly on the liver via hepatic estrogen receptors. These conclusions are corroborated by studies of hepatic estrogen receptor concentrations.
