1. Protective effects of abdominal electroacupuncture on oxidative stress and inflammation due to testis torsion/detorsion in rats
PURPOSE:To evaluate the effects of acupuncture (Ac) and electroacupuncture (EAc) on oxidative stress and inflammation in testis torsion/detorsion (T/D) model in rats.METHODS: Thirty male Wistar rats were randomized into five groups. G1 Group (Sham) served as control. The remaining groups were submitted to spermatic cord torsion (720°) for 3 hours, followed

2. USO DE DILUENTES ALTERNATIVOS A BAIXAS TEMPERATURAS NA MANUTENÇÃO DA QUALIDADE ESPERMÁTICA DO SÊMEN SUÍNO / USE OF ALTERNATIVE SOLVENTS AT LOW TEMPERATURES IN THE MAINTENANCE OF SPERM QUALITY OF SWINE SEMEN
Countless studies have been conducted with the purpose of improving the conservation of boar semen, either with the use of diluents or alternative temperature ranges, or adding antioxidants or amino acid to the diluent. The present study aimed to define an alternative diluent and temperature preservation of boar semen and evaluate the effects of adding trolo

3. Complemental tests in semen and evaluation of the anionic proteins and peptides differentially synthesized in seminal plasma of Nelore bulls classified as sound and unsound for breeding / Testes complementares em sêmen e avaliação da síntese diferencial de proteínas e peptídeos aniônicos em plasma seminal de touros da raça Nelore classificados em aptos e inaptos à reprodução
The main analyses performed routinely to assess the sperm quality are the spermatic motility and morphology for the measurement bulls fertility. Several complementary techniques are used to improve bulls fertility evaluation. Each technique is related to different aspects of sperm quality and their results are not yet fully understood. Four experiments were

4. Criopreservação de sêmen canino com um diluidor à base de água de coco na forma de pó (ACP-106): Efeito da temperatura de adição do glicerol e da adição de antibiótico. / Cryopreservation of canine semen with a diluent based on coconut water as a powder (ACP-106 ): Temperature effect of adding glycerol and the addition of antibiotic.
Researches have been developed aiming to improve the already existing protocols for canine semen freezing. In this way, this work was divided in two experiments, aiming: 1) to compare the effect of glycerol addition at two temperatures (27 and 4C) on canine semen extended and frozen with powdered coconut water extender (ACP-106); 2) to analyze the effect of

5. Diferentes concentraÃÃes espermÃticas na inseminaÃÃo artificial intra-uterina em suÃnos / Different spermatic concentrations on the intrauterine artificial insemination in swine
The aim of this work was to evaluate the efficiency of the intrauterine insemination (IUI) in swine, considering the conception rate, farrowing rate, litter size (alive, stillborn and mummified) and pig born weight. In the IUI, the females had been inseminated at 24 and 48 hours after the oestrus detection, and had been used the inseminating doses with 500 m

6. Efeito de diferentes suplementaÃÃes dietÃticas sobre os perfis metabÃlico e lipÃdico em caprinos adultos
Twenty-seven mature male goat adult were used in order to examine the effect of dietary supplementation with sunflower oil (2%, 4% and 6%) in different protein levels (12%, 15% and 18%) for 60 days, on the metabolic profile, including animals clinical biochemical parameters evaluation, lipid profile and testosterone levels. The experiment was developed in th

7. Ativadores e concentraÃÃes de metanol e dimetilsulfÃxido na qualidade do sÃmen criopreservado de curimba (Prochilodus lineatus) / Activators and concentrations of methanol and dimethyl sulphoxide in quality of cryopreserved sperm of curimba Prochilodus lineatus
This trial was carried out from November 2005 to January 2006, in order to compare toxicity and the effect of the addition of cryoprotectant and activator solutions to curimba Prochilodus lineatus semen, before and after freezing. Semen samples of 10 breeders were analyzed and diluted in eight cryoprotectants solutions (1:4). These were composed for methanol

8. Estudo experimental das alterações agudas na glicemia e concentrações testiculares de ATP e glicose induzidas por torção unilateral, in vivo / In vivo acute changes in ATP and glucose concentrations in the rat testicles following unilateral torsion: experimental study
A torção do cordão espermático é a emergência geniturinária mais comum na idade pediátrica. Foram estudadas as alterações metabólicas agudas nas concentrações testiculares de ATP e glicose após uma hora de isquemia induzida por torção do cordão espermático. Sessenta ratos wistar machos pré-púberes, foram distribuídos em 2 grupos de 30 an

9. Secretion of Unconjugated Androgens and Estrogens by the Normal and Abnormal Human Testis before and after Human Chorionic Gonadotropin
The secretion of androgens and estrogens by normal and abnormal testes was compared by determining the concentrations of dehydroepiandrosterone (DHEA), androstenedione (Δ4A), testosterone (T), estrone (E1), and 17β-estradiol (E2) in peripheral and spermatic venous plasma samples from 14 normal men and 5 men with unilateral testicular atrophy. Four normal m

10. Estradiol and Testosterone Secretion by Human, Simian, and Canine Testes, in Males with Hypogonadism and in Male Pseudohermaphrodites with the Feminizing Testes Syndrome
The role of the human testis in the production of 17β-estradiol (E2) was investigated by determining the concentration of E2 and testosterone in peripheral and spermatic vein plasma samples. Specimens were obtained from eight normal men, three men with hypogonadism, and two patients with the incomplete form of the feminizing testes syndrome. For comparison,
