1. Does asporin have a role in polycystic ovary syndrome? A pilot study
SUMMARY OBJECTIVE: Asporin is secreted by theca cells in the mouse ovaries and is an effective marker at the gonadotropin-independent stage in secondary follicle development. It has an inhibitory effect on transforming growth factor beta and bone morphogenic proteins, which are involved in androgenesis process. Our aim was to compare serum asporin levels of

2. Classic and current concepts in adrenal steroidogenesis: a reappraisal
ABSTRACT Adrenal steroid biosynthesis and its related pathology are constant evolving disciplines. In this paper, we review classic and current concepts of adrenal steroidogenesis, plus control mechanisms of steroid pathways, distribution of unique enzymes and cofactors, and major steroid families. We highlight the presence of a “mineralocorticoid (MC) pat

3. Melatonin may prevent or reverse polycystic ovary syndrome in rats
RESUMO OBJETIVO Avaliar os efeitos ovarianos da melatonina (Mel) em ratas com síndrome dos ovários policísticos (SOP) antes e após a indução do estro-permanente. MÉTODOS Trinta e duas ratas com ciclos estrais regulares foram igualmente divididas em quatro grupos: 1) GCtrl - fase de estro. 2) GSOP - fase de estro-permanente. 3) GMel1 – tratadas p

5. Effect of bee venom on IL-6, COX-2 and VEGF levels in polycystic ovarian syndrome induced in Wistar rats by estradiol valerate
Background : Polycystic ovarian syndrome (PCOS) is a low-grade inflammatory disease characterized by hyperandrogenemia, hirsutism, chronic anovulation and vascular disorder. Interleukin-6 (IL-6), cyclooxygenase-2 (COX-2) and vascular endothelial growth factor (VEGF) are triggered by inflammatory stimuli and lead to angiogenesis and pathogenesis of the ovary

6. Bee venom treatment reduced C-reactive protein and improved follicle quality in a rat model of estradiol valerate-induced polycystic ovarian syndrome
Polycystic ovarian syndrome (PCOS) is a low grade inflammatory disease characterized by hyperandrogenemia and chronic anovulation. C-reactive protein (CRP), released by adipocytes, plays a key role in PCOS. Apis mellifera honeybee venom (HBV) contains a variety of biologically active components with various pharmaceutical properties. This study was designed

7. Alteração do ciclo menstrual na adolescência: manifestação precoce da Síndrome Metabólica? / Alteration on menstrual cycle in adolescence: early manifestation of Metabolic Syndrome?
Evidences have appeared throughout the last decade that the metabolic syndrome(MS) (increasingly reported among teens) begins in intra-uterine life and its signs and symptoms are already present in adolescence. Nevertheless, specific diagnostic criteria for this age group are missing. The menstrual cycle represents the result of the normal functioning not on

8. Integração entre vias metabolicas e inflamatorias durante a esteatose hepatica induzida por dieta hiperlipidica / Integration between metabolic and inflammatory pathways during hepatic steatosis induced by hiperlipidic diet
Obesity has grown as an epidemiological phenomenon that threatens millions of people worldwide, and particularly those living in western, developed countries. Besides its multiple behavioral and social problems, obesity contributes considerably to increase morbidity and mortality due to its common association with diseases that compose the metabolic syndrome

9. Transvaginal ultrasound with Doppler velocimetry to study stromal volume and thickness and vascularization of the ovaries in polycystic ovary syndrome / Ultra-sonografia transvaginal com dopplervelocimetria no estudo do volume, da espessura do estroma e da vascularização dos ovários na síndrome dos ovários policísticos
INTRODUCTION: Polycystic ovary syndrome (PCOS) is one of the most controversial conditions in gynecological endocrinology. After the symposium in Rotterdam in 2003, the importance of ovary morphology has become evident for the diagnosis and the composition of phenotypes. Transvaginal ultrasound with Doppler velocimetry can help us analyze the variables impli

10. AnÃlise histoquÃmica e morfomÃtrica de rins de neonatos nascidos de ratas tratadas com dexametasona para ovÃrios policÃsticos
A dexametasona tem sido empregada no tratamento de algumas patologias do aparelho reprodutor feminino, como por exemplo, a sÃndrome dos ovÃrios policÃsticos. No entanto, vÃrios autores relatam que a administraÃÃo de glicocorticÃides em ratas durante a prenhez induz na prole uma reduÃÃo do nÃmero de glomÃrulos e desenvolvimento de hipertensÃo na f

11. Regulação hormonal da prostata de femeas do gerbilo : avaliação estrutural, citoquimica e imunocitoquimica / Hormonal regulation of the gerbil female propstate: morphology, cytochemistry and immunocytochemistry
The female prostate is a functionally active gland found in several species of mammals, including humans and rodents. In adult female gerbils, the prostate presents a paraurethral location, showing close contact with the wall of urethra in its median and distal portions. This gland is homologue to the ventral prostate of male rodents and it is formed by a cl

12. Steroid-induced polycystic ovaries in rats: effect of electro-acupuncture on concentrations of endothelin-1 and nerve growth factor (NGF), and expression of NGF mRNA in the ovaries, the adrenal glands, and the central nervous system
Previous studies on the effect of repeated electro-acupuncture (EA) treatments in rats with steriod-induced polycystic ovaries (PCO), EA has been shown to modulate nerve growth factor (NGF) concentration in the ovaries as well as corticotropin releasing factor (CRF) in the median eminence (ME). In the present study we tested the hypothesis that repeated EA t
