Changes of bone mineral density in vertebrae of rats subjected to hindlimb unload

The suspension of rats by the tail model is used to investigate the behavior of bone in animals unable to move around. Bone is an adaptative tissue that develops in structure and function, among other factors, in response to mechanical forces applied to it and metabolic demands that it will suffer. The absence of mechanical forces and deformation of bone that occurs causes a decrease in calcium deposition in th...

Congenit anomaly in vessels of base in a foal heart

Anomalias congênitas do coração e de grandes vasos estão entre as mais comuns encontradas em animais, porém são raras em eqüinos. Este relato descreve uma anomalia cardíaca que apresenta confluência entre a parede da aorta e do tronco pulmonar, ramificação da veia cava caudal no átrio esquerdo com presença de válvula e conseqüentemente posição errônea do coração na cavidade torácica de um potro da raça Quarto-d...

Morphological analysis of ovaries of Nelore bovine fetuses (Bos primigenius ind...

In this research, twenty Nelore female fetuses in different phases of gestation were collected. The right and left ovaries were dissected and measured for verification of the length and width and soon after that, the entire ovaries were fixed in 4.00% tamponed paraformaldeido, processed and enclosed in paraplastic. The histological sections with 5 mm were stained with hematoxilin and eosin, Masson's trichrome (...

Caracterização morfológica do útero e tubas uterinas de fetos bovinos da raça N...

For the accomplishment of this research, twenty Nelore female fetuses in different phases of gestation were collected. The uterine horns and oviducts were dissected, measured and fragments were fixed in 4.00% tamponed paraformaldeid, processed and enclosed in paraplastic. The sections of 5mm were stained with hematoxilin and eosin, Masson's trichrome (to colagens fibers), Verhoeff (to elastic fibers) and with r...

Lienales artery and vein of bovines of Nelore breed

The splenic artery describes two behaviors before penetrating into the hilus, constituting the group I (90%) with an extrahilar branch, and the group II (10%), having two of these branches, originating an average of 13 branches to the cranial edge, and 10 directed to the caudal edge. The splenic vein frequently (96.6%) is represented by a unique vessel stretching longitudinally in the dorso-ventral axis, where ...

Morfology study of the spermatic cord in Corriedale sheeps (Ovis aries, L. 1758)

We have been studied histological aspect of 40 pairs of spermatic cord in adults Corriedale sheep. It was observed that structures were wrapped up a thin layer of dense fibroelastic connective tissue with variable thickness and folding, recovered by mesotelium, which involves all the neurovascular cord, and forms the mesoductus deferents. Under this arrangement there was a layer of loose fibroelastic tissue inv...

Irrigation of equine testis of the English Thoroughbreds

The testicular arteries, as well as the number of branches, and the distribution of its penetrating branches were studied in 30 pairs of adult equine testis of the English Thoroughbreds, provided from São Paulo Jockey Club, by using vascular corrosion models after injecting the vinyl acetate into the testicular arteries. In this species, the testicular arteries presented 5 distinct types of vascular arrangement...

The distribution of the ramus principalis sinister of lhe biliary ducts of 40 adult females of Jaffarabadi breed buffaloes was studied after latex Neoprenie 650 and Celobar injections through theductus choledochus. Following fixation in 10% formaldehyde solution, radiograms were taken from the specimens and then dissected. The ramus principalis sinister is formed usually by several roots, ramus medialis lobi si...

Morfologia e inervação do diafragma de veados (Manzana americana, Manzana simpl...

The morphology and innervation of the diaphragm in 3 species of deers (Manzana americana, Manzana simplicicornis and Blastoceros bezoarticus) were dissected after having been fixed in 10% formaldehyde solution. The diaphragm in 3 species appeared thin, having a reduced peripheral muscular portion, a large centrum tendineum and thick pillars. The phrenic nerves presented a terminal trifurcation (45% on the right...
