2. Androgen insensitivity syndrome: a review
ABSTRACT Androgenic insensitivity syndrome is the most common cause of disorders of sexual differentiation in 46,XY individuals. It results from alterations in the androgen receptor gene, leading to a frame of hormonal resistance, which may present clinically under 3 phenotypes: complete (CAIS), partial (PAIS) or mild (MAIS). The androgen receptor gene has 8

3. Deficiency of sex hormones does not affect 17-ß-estradiol-induced coronary vasodilation in the isolated rat heart
The relaxation of coronary arteries by estrogens in the coronary vascular beds of naive and hypertensive rats has been well described. However, little is known about this action in gonadectomized rats. We investigated the effect of 17-ß-estradiol (E2) in coronary arteries from gonadectomized rats, as well as the contributions of endothelium-derived factors

6. Efeitos neuroendócrinos da interação entre hormônios sexuais e manipulação neonatal em ratos machos e fêmeas adultos
Influências de secreções endógenas e estímulos ambientais durante o período neonatal parecem ser determinantes para programar a atividade neuroendócrina e comportamental na vida adulta. O propósito do presente trabalho foi estudar a interação entre os hormônios gonadais e a manipulação durante o período neonatal sobre a concentração plasmáti

7. Determination of the Sexual Phenotype in a Child with 45,X/46,X,Idic(Yp) Mosaicism: Importance of the Relative Proportion of the 45,X Line In Gonadal Tissue. / Determinação do Fenótipo Sexual em uma Criança com Mosaicismo 45,X/46,X,Idic(Yp): Importância da Proporção Relativa da Linhagem 45,X no Tecido Gonadal.
We report here on a girl who, despite her 45,X/46,X,der(Y) karyotype, showed no signs of virilization or physical signs of the Ullrich-Turner syndrome [UTS], except for a reduced growth rate. After prophylactic gonadectomy due to the risk of developing gonadoblastoma, the gonads and peripheral blood samples were analyzed by fluorescence in situ hybridization

9. 5 alfa - reductase type 2 deficency : importance of hormonal evaluation in the diagnosis, including anti-mullerian hormone levels / Deficiencia da 5 alfa - redutase tipo 2 : importancia da avaliação hormonal no diagnostico, incluindo dosagem do hormonio anti-mulleriano
The clinical features of 5a-reductase 2 deficiency patients are hardly distinguishable from those of the other causes of pseudohennaphroditism, especially androgen insensitivity syndromes; the diagnosis becomes even more difficult when family history is unremarkable and there are no clues to a pattem of inheritance. The aim of this study was to eValuatethe h

10. Investigações preliminares sobre as alterações sexo-dependentes da glicemia produzidas por canatoxina em ratos
1. The chronical administration of canatoxin (0.1mg/kg of ac:tive protein) to intac:t maIe and femaIe rats induced a pronounced sex-reIated dependent aIteration upon the bIood glucose Ievels of the animaIs. Thus, whiIe the males exhibited hypergIycemia the femaIes showed hypoglycemia. 2. A rise in the circuIating glucose IeveIs comparable to that seen in maI

11. Influence of Gonadal Factors on Skin Test Reactivity of CFW Mice to Candida albicans
Sex differences in the delayed skin test response to Candida albicans were studied in gonadectomized and control CFW mice sensitized either actively with sonically treated antigen or passively with lymphoid cells. In mice actively sensitized with antigen, the responses to candida skin testing were larger in the female. In both sexes, the skin test responses

12. Influence of Gonadectomy on Candida albicans Urinary Tract Infection in CFW Mice
Candida albicans appeared in the urine of approximately 80% of CFW mice of both sexes within 2 weeks after intraperitoneal inoculation. During a follow-up period of 10 weeks, candiduria tended to clear, but persisted in 37% of males as compared to only 16% in females. Autopsy kidney cultures yielded candida in 53% of males as compared to 25% of females. Urin
