1. Effects of folic acid administration on testicular ischemia/reperfusion injury in rats
Abstract Purpose: To determine the effect of folic acid (FA) on experimental testicular ischemia/reperfusion (I/R) in rats. Methods: Sixty male Wistar rats were randomly divided into 6 groups. The control group received physiologic saline orally. The sham-operated group received physiologic saline orally then exposed to midline laparotomy without clamping

2. MAPK immunoreactivity in streptozotocin-induced diabetic rat testis
PURPOSE: To evaluate the alterations of two mitogen-activated protein kinases (MAPK)s, extracellular signal regulated kinase (ERK) and c-Jun NH2 terminal kinase (JNK), in the testes of male rats with experimental diabetes. METHODS: Twenty males Sprague-Dawley rats were randomly divided into a control group (n=8) and a diabetes group (administration of

3. The effects of carvedilol on ischemia-reperfusion injury in the rat testis
Objective: To analyze the oxidative damage and histopathological alterations caused by ischemia-reperfusion (I/R) injury and ameliorative effects of carvedilol (CVD) in the rat testis. Materials and Methods: Twenty-one male rats were randomized into 3 groups as follows: Group I (n = 7); control (sham) group, Group II (n = 7); I/R group, in which I/R injur

4. Colon cancer and swimming exercise: effect on wistar rat testes
This study was undertaken to determine whether colon cancer (CC) and chronic swimming exercise alter rat testis. Eleven weeks old rats were distributed into control group (n=6) and the groups that were induced to develop CC by dimethylhydrazine injections (nEG, EG0, EG2 and EG4; n=10 each group). In the group nEG, the rats did not swim, whereas groups EG0, E

5. Danos oxidativos e histológicos crônicos causados pelo cádmio no fígado e na espermatogênese de ratos / Oxidative and histological chronic damage caused by cadmium in the liver and in spermatogenesis of rat
Diversos estudos demonstram que o cádmio induz efeitos prejudiciais nos sistema reprodutivo e hepático, porém estudos sobre alterações causadas por baixas doses ainda estão pouco descritos. Este estudo investigou os danos oxidativos e histológicos crônicos em testículo e fígado de ratos expostos a baixas concentrações de cádmio. Cinco grupos exp

6. Post-partum testosterone administration partially reverses the effects of perinatal cadmium exposure on sexual behavior in rats
This study investigated the effects of perinatal cadmium exposure on sexual behavior, organ weight, and testosterone levels in adult rats. We examined whether immediate postpartum testosterone administration is able to reverse the toxic effects of the metal. Forty pregnant Wistar rats were divided into three groups: 1) control, 2) 10 mg kg-1 cadmium chloride

7. Ações da epitestosterona através de um mecanismo de membrana em células de Sertoli : implicações no desenvolvimento sexual
Introduction: Epitestosterone is the 17¿-epimer of testosterone. It seems to possess an antiandrogenic activity, as well as a neuroprotective effect. The mechanism of action of epitestosterone has not been elucidated. Objective: The aim of this work is to investigate the non-classical effect of epitestosterone on the membrane of Sertoli cells from testis of

8. Vias de sinalização intracelular envolvidas no efeito proliferativo de relaxina em células de sertoli / Intracelular signaling pathways involved in the proliferative effect of relaxin in rat Sertoli cells
Relaxin is an insulin-related peptide that activates the G-protein coupled receptor RXFP1. Although relaxin plays an important role in female reproduction its physiological role in the male reproductive system is still unclear. We have previously demonstrated that relaxin and RXFP1 are expressed in testis (FILONZI et al., 2007; CARDOSO et al., 2010). Both re

9. The effect of microgravity on tissue structure and function of rat testis
To explore whether an environment of weightlessness will cause damage to the reproductive system of animals, we used the tail-suspension model to simulate microgravity, and investigated the effect of microgravity on the tissue structure and function of the testis in sexually mature male rats. Forty-eight male Wistar rats weighing 200-250 g were randomly assi

10. Mastócitos no lobo ventral da próstata, no epidídimo e no testículo de ratos UChB (consumidores voluntários de etanol a 10%) / Mast cells in the ventral prostate, epididymis and testis of UchB - ethanol preferring rats (10% v/v high ethanol voluntary intake)
Alcoholism has reached alarming proportions throughout the world, but there is little research on the inflammatory effect of ethanol in the reproductive organs. The mast cell, which is one of the main cells involved in inflammatory processes, is known to have two subtypes in rodents, connective (CTMC) and mucosal (MMC) tissue. Hence, the aim of this work is

11. Oxidative stress and reproductive disorders in hyperglycemic male rats : antioxidant potencial of vitamins C and E / Relação entre estresse oxidativo e desordens reprodutivas em ratos machos hiperglicemicos : potencial antioxidante das vitaminas C e E
The hyperglycemia is related to disorders in the male reproductive system. When induced chemically, it can reduce the sexual hormones level, reproductive organs weight, sperm concentration, and fertility as well as the male rat sexual behavior. In men, the hyperglycemia can lead to sexual impotence, libido and spermatogenesis reduction. However, the main

12. Analysis of the expression profile and distribution of EFHC1 gene transcript during rodent brain development and in the adult animal / Analise da expressão e localização do transcrito do gene EFHC1 no cerebro de roedores durante o desenvolvimento e no animal adulto
Epilepsy is a frequent condition that affects around 1.5% of general population and is considered worldwide as a public health problem. The term epilepsy refers to a group of chronic neurological disorders with different etiologies and prognostics. However, a common characteristic of all epilepsies is the recurrence of seizures. Juvenile myoclonic epilepsy (
