13. Effects of the association of cadmium chloride and guarana (Paullinia cupana) on the testis of wistar rats : morphometry, structure and ultrastructure / Efeitos da associação de cloreto de cadmio e guarana (Paullinia cupana) no testiculo de ratos Wistar : analise morfometrica, estrutural e ultraestrutural
Guaraná (Paullinia cupana Mart. var. Sorbilis) is a Brazilian plant, found in the Amazon basin. Previous studies have demonstrated the antioxidant properties of guaraná and its potential to neutralize free radicals. This plant is traditionally used for several therapeutic purposes and, recently, has been investigated to ascertain the potential of guaraná

14. Efeitos da oxigenoterapia hiperbárica após isquemia hepática segmentar normotérmica e reperfusão, em coelhos:: Avaliação bioquímica, morfológica e da microcirculação hepática pelo ultra-som contrastado
Interruption of blood flow to an organ or tissue (ischemia) and subsequent reperfusion lead to an acute inflammatory response that may cause significant cellular damage and organ dysfunction. It is called ischemia/reperfusion injury. Hepatic ischemia/reperfusion injury is characterized by circulatory and metabolic derangements, liver dysfunction and tissue d

15. Testicular morphometry and morphology in insectivorous bat (Molossus molossus Pallas, 1776) (Chiroptera, Molossidae) / Morfologia e morfometria testicular em morcego insetívoro (Molossus molossus Pallas, 1776) (Chiroptera, Molossidae)
Testicular morphometric analysis have been implemented in order to infer on the gonadal dynamics and reproductive capacity of the insectivorous bat Molossus molossus in the southeast of Minas Gerais, Brazil, collected during the four annual climatic seasons, from 2007 to 2008. After euthanasia animal tissues were collected and included in methacrylate, and h

16. Morphology of the reproductive system of male thorny lobster Panulirus argus (Latreille, 1804) (Crustacea: Decapoda: Palinuridae) of coastline of the State of Cearà / Morfologia do sistema reprodutor masculino da lagosta espinhosa Panulirus argus (Latreille, 1804) (Crustacea: Decapoda: Palinuridae) do Litoral do Estado do CearÃ
The fishery of the spiny lobster Panulirus argus, found in the coast of the state of CearÃ, has been declining in the last years. Studies about the reproductive aspects of lobsters are still scarce, mainly for the males, needing investigations in the area of reproductive biology. The present study describes the morphology of the male reproductive system of

17. Morfologia dos órgãos reprodutores masculinos da ema (Rhea americana americana) / Morphology of the organ reproductive masculine of the ema (Rhea americana americana)
A ema (Rhea americana americana) é uma ave que pertence ao grupo das Ratitas, ordem Rheiforme e a família Rheidae. Neste trabalho foram analisadas as características morfológicas, macroscópicas e microscópicas, dos órgãos do aparelho reprodutor masculino (testículos, epidídimos, ductos deferentes e falo) e a cloaca em 23 emas, quatro filhotes com d

18. Relationship between the maternal diabetes and the sexual development of the male rat offspring / Relação entre o diabete materno e o desenvolvimento sexual da prole masculina de ratos
Diabetes melllitus is a group of metabolic disorders of multiple etiology, characterized by defects in the secretion and/or action of insulin. The causes of the disease can be genetic and/or environmental. Diabetes is one of the most common metabolic complications during pregnancy and is associated with an increased risk of maternal and neonatal morbidities.

19. Testis and vas deferens morphology of the red-clawed mangrove tree crab (Goniopsis cruentata) (Latreille, 1803)
Caranguejos são um importante recurso econômico para a população litorânea e o conhecimento dos aspectos reprodutivos fornecem base para o manejo das espécies. O presente estudo descreve a estrutura do testículo e do vaso deferente do caranguejo Goniopsis cruentata, e discute aspectos relacionados à formação do espermatofóro. O testículo é um ó

20. Macro and microscopical aspects of the male genital organs in the Pantanal alligator (Caiman crocodylus yacare) - DAUDIN 1802 / Aspectos macro e microscópicos dos órgãos genitais masculinos no jacaré-do-Pantanal (Caiman crocodylus yacare) - DAUDIN 1802
Ten Young-aged male Pantanal alligators (Caiman crocodylus yacare) were used; seven specimes were destinated to macroscopic study and the other three were used in the study of light microscopy. After the opening of the pleuroperitoneal cavity, we observed and identified that testes are in pairs and adhered to the dorsal wall of the pleuroperitoneal cavity. T

21. Morphometric evaluation of the testis and spermatogenesis in adult oncelot (Leopardus pardalis, Linnaeus, 1758) / Avaliação morfométrica do testículo e da espermatogênese de jaguatiricas (Leopardus pardalis, Linnaeus, 1758) adultas
To study the spermatogenetic cycle in ocelots, were used, three adult males, proceeding from the Centro de Triagem de Animais Silvestres the Federal University of Viçosa and two adult males proceeding from the Fundação Zoobotânica of Belo Horizonte/MG/Brazil, authorized by the IBAMA-MG. These animals were submitted to general anesthesia, weighed and its

22. Parametros reprodutivos masculinos e fertilidade de ratos adultos expostos ao inseticida fenvalerato / Male reproductive parameters and fertility of adult rats exposed to fenvalerate
Fenvalerate is a synthetic pyrethroid insecticide widely used in agriculture to control a variety of insects. Although it is considered to be of low acute toxicity to mammals, studies have showed that pyrethroids can have estrogenic activity and can act as endocrine disruptors, causing important reproductive impairment in males. It is documented in the liter

23. ESTUDO MORFOFUNCIONAL DAS CÉLULAS DE SERTOLI DE RATOS ALBINOS TRATADOS COM ETOPOSIDE NA FASE PRÉ-PÚBERE. / Morphological and functional evalution of Sertoli cells from albino treated with etoposide during preopubertal phase. / ESTUDO MORFOFUNCIONAL DAS CÉLULAS DE SERTOLI DE RATOS ALBINOS TRATADOS COM ETOPOSIDE NA FASE PRÉ-PÚBERE. / Morphological and functional evalution of Sertoli cells from albino treated with etoposide during preopubertal phase.
Spermatogenesis is a complex and controlled process in which Sertoli cells play a key role. In the testis, endocrine, paracrine and autocrine mechanisms that control spermatogenesis occurrence. The Sertoli cells synthesize substances which are essential for these mechanisms. Among them is transferrin. This protein is an important iron transporter that binds

24. Morphofunctional analysis of the testis and spermatogenesis in adult African lions (Panthera leo, Linnaeus, 1758) / Análise morfofuncional do testículo e espermatogênese de leões africanos (Panthera leo, Linnaeus, 1758) adultos
The study of the testis morphology and the spermatogenetic process in wild animals is fundamentally important for the knowledge about the physiologic patterns by which the assisted reproduction protocols are established. The following objectives were proposed in this study: to describe the data of both testis morphometry and seminiferous tubule; to quantify
