1. Quantification of collagen fibers in canine uteri treated with medroxyprogesterone acetate
ABSTRACT: Collagen plays essential roles in remodeling uterine tissue during decidualization, implantation, pregnancy and involution. To understand whether the progestational agent medroxyprogesterone acetate (MPA) can modify the organization and deposit of collagen in the uteri of normal bitches (Canis Tlupus familiaris), we assessed uterine tissues by hist

2. Gene expression of estrogen and oxytocin receptors in the uterus of pregnant and parturient bitches
In the canine species, the precise mechanisms of pregnancy maintenance and the initiation of parturition are not completely understood. The expression of genes encoding the receptors for estrogen (ERα mRNA) and oxytocin (OTR mRNA) was studied in the endometrium and myometrium during pregnancy and parturition in dogs. Real-time PCR was performed to quantify

3. Ablação endometrial com ácido tricloroacético em ratas: estudo histomorfométrico e histológico / Endometrial ablation using trichloroacetic acid in rat model: histomorphometric and histologic evaluation
INTRODUCTION: Dysfunctional uterine bleeding is one of the most prevalent causes of uterine bleeding and it is related to hormonal variations without organic causes. Endometrial ablation is a therapeutic option but the methods are frequently expensive and dependent of high cost technologies. The objective of the present study is to develop an animal model of

4. Aspectos morfológicos do útero de Macaco Rhesus (Macaca mulatta - Zimmermann, 1780) em fêmeas nulíparas, primíparas e pluríparas / Morphological aspects of uterus in nulliparous, primiparous and pluriparous Rhesus Macaques (Macaca mulatta - Zimmermann, 1780)
Foram utilizados 15 úteros de macacos Rhesus (Macaca mulatta), sendo 5 fêmeas nulíparas, 5 primíparas e 5 pluríparas. Todas as fêmeas eram maduras sexualmente, tinham de 38 a 87 meses de idade e pesavam entre 4,9 a 7,39 Kg. Em todos os animais foram feitos o estudo topográfico, biometria dos órgãos, microscopia de luz e quantificação de colágeno

5. xpression of estrogen and progesterone receptor genes in endometrium, myometrium and vagina of postmenopausal women treated with estriol
CONTEXT AND OBJECTIVE: Estriol is an estrogen with considerably weaker stimulatory effects on endometrial proliferation than estradiol. A study was conducted to determine the level of estrogen receptors (ERs) and progesterone receptors (PRs) in women who received 14-day vaginal estriol therapy, compared with those who did not receive this therapy. ER and PR

6. Characterization of proteoglycans in the mouse uterus during the estrous cycle and in ovariectomized animals: analysis of the effects of castration and hormone replacement. / Caracterização de proteoglicanos do útero de camundongos durante o ciclo estral e em animais ovarectomizados: análise dos efeitos da castração e da reposição hormonal.
A matriz extracelular (MEC) dos tecidos uterinos é altamente remodelada na gestação de camundongos. Os objetivos deste estudo foram avaliar a influência dos hormônios ovarianos estrógeno (E2) e progesterona (P4) sobre a estrutura dos tecidos uterinos de camundongo e a deposição dos proteoglicanos decorim, biglicam, fibromodulim, lumicam, perlecam e v

7. eCG e densidade vascular em úteros bovinos / eCG and vascular density of bovine uterus
Follicle dynamic, as well as the uterus preparation for gestation, is dependent of an adequate vascularization establishment. Currently, many studies point towards the importance of eCG treatment following fixed-time artificial insemination (FTAI), in a manner to improve ovulation and gestational rates. Moreover, eCG have been implicated in angiogenesis, lea

8. Expression of the canine estrogen and oxytocin receptor genes in the endometrium, myometrium and placenta during pregnancy and parturition / Expressão gênica dos receptores de estrógeno e ocitocina no endométrio, miométrio e placenta durante a gestação e parto em cadelas
As diversas interações hormonais durante e gestação e parto na espécie canina são parcialmente conhecidas. A resposta dos tecidos frente ao estímulo hormonal é dependente da expressão gênica de seus receptores, bem como da concentração local dos hormônios. Desta maneira, o presente estudo apresentou como objetivos: caracterizar a expressão gên

9. Efeitos do ultra-som pulsado de baixa intensidade sobre a musculatura lisa e sobre o epitélio endometrial em úteros de ratas adultas, após uterotomia: estudo experimental / Effects of the pulsed ultrasound of low intensity on the flat musculature and on the epithelium endometrial in uteruses of adult female rats, after uterotomia: experimental study
Esta investigação experimental teve como finalidade de avaliar os efeitos do ultra-som pulsado de baixa intensidade sobre a regeneração do miométrio e do endométrio de ratas submetidas à uterotomia. Foram utilizadas neste experimento 20 ratas adultas da raça Wistar, submetidas a uma uterotomia mediante incisão longitudinal de 1,5 cm total de uma das

10. Involvment of nitric oxide, prostaglandins and tumor necrosis factor on the development of ectopic endometrial implants (peritoneal) and its repercussions on pain and fertility in rats / Envolvimento de óxido nítrico, prostaglandinas e fator de necrose tumoral no desenvolvimento de implantes endometriais ectópicos (peritoneais) e suas repercussões sobre a dor e infertilidade em ratas
Endometriosis is a disease characterized by the presence of endometrial glands and stroma out of the uterine cavity and of the myometrium. It may cause tumor, pain (chronic pelvic pain, dyspareunia and dysmenorrhea) and infertility. Currently available evidence indicates that endometrial cells misplaced during menses into the peritoneal cavity in women with

11. Galactosaminoglycans from normal myometrium and leiomyoma
In many tumors, the amount of chondroitin sulfate in the extracellular matrix has been shown to be elevated when compared to the corresponding normal tissue. Nevertheless, the degree of chondroitin sulfate increase varies widely. In order to investigate a possible correlation between the amount of chondroitin sulfate and tumor size, several individual specim

12. Experimental toxoplasmosis in Balb/c mice. Prevention of vertical disease transmission by treatment and reproductive failure in chronic infection
In a study of congenital transmission during acute infection of Toxoplasma gondii, 23 pregnant Balb/c mice were inoculated orally with two cysts each of the P strain. Eight mice were inoculated 6-11 days after becoming pregnant (Group 1). Eight mice inoculated on the 10th-15th day of pregnancy (Group 2) were treated with 100 mg/kg/day of minocycline 48 h aft
