Collateral branches of the aortic arch in the greater Rhea (Rhea americana americana Linnaeus, 1758)

The greater rhea ( Rhea americana americana ) is a bird of the Rheidae family, and is known as a ratite for being a flightless bird. This animal has great reproductive and productive potential, according to the products and by-products that it can provide such as meat, leather, feathers and fat which are very popular in the world market. Given its economic importance and lack of information in the literature on its morphology, especially in regard to its cardiovascular apparatus, this study aimed to describe the collateral arteries of the aortic arch, in order to establish the origin and distribution of arteries and thus contribute information to the biology of the species. The bodies of 20 young and adult rheas of both sexes which had died from natural causes and were being stored in a freezer at CEMAS / UFERSA were used. The study was approved by CEUA /UFERSA (Opinion No. 09/2015, process No. 23091.004968 / 2015-23). The animals were thawed and had the cannulated thoracic aorta artery and the vascular system perfused with Neoprene 450 latex colored with yellow pigment. Subsequently, the animals were fixed in 3.7% aqueous solution of formaldehyde, and after 72 hours dissections were carried out, images were obtained and schematic drawings were prepared. The right and left brachiocephalic trunks emerged from the aortic arch in 100% of the specimens from the right brachiocephalic trunk origined a common trunk the thyroid arteries, syringotracheal trunk, vertebral artery, superficial lateral cervical artery, basecervical artery, and ascending esophageal artery. The left brachiocephalic trunk collaterally stemmed in the left common carotid artery, which in turn led to the left internal carotid and a common trunk which stemmed the thyroid arteries, the syringotracheal trunk, vertebral artery, superficial lateral cervical artery, basecervical artery and descending esophageal artery. At the end of its trajectory, the right and left brachiocephalic trunks give rise to the right and left subclavian arteries, which in turn, stem the sternoclavicular, axillary, and intercostal arteries, pectoral trunk, cranial pectoral arteries, pectoral caudal artery and collateral branches of the pectoral trunk. Based on the results, it was concluded that the aortic arch in rheas issued right and left brachycephalic trunks.

Morfologia das glândulas salivares maiores em cutias (Dasyprocta leporina Linnaeus, 1766)

Studies on wild animal morphology serve as theoretical basis for the management and conservation of different species, because they provide necessary information for measures to keep these animals in captivity, in their natural habitat or even to reintroduce them into their original habitat. Studies about the morphology of the red-rumped agouti, Dasyprocta leporina, approach the various organic systems, but not a single study refers to topography and structure arrangement of their salivary glands. Thus, this paper aimed to gross and microscopic description of the larger salivary glands of red-rumped agouti. Ten adult D. leporina were used to study the macroscopic aspect of the glands, as well as the microscopic aspects with light microscopy, scanning and transmission electronic microscopy. Four larger salivary glands were identified: parotid glands, mandibular glands, zygomatic glands and sublingual glands. The tubuloacinar glands contained in their parenchyma ducts of extremely varied sizes. With exception of the strictly serous parotid glands, the others were mixed, and only the mandibular glands had granulous ducts. The red-rumped agouti with four pairs of larger salivary glands may be a model for studies concerning the anatomical changes in rodents for adaptation to various habitats.

Impact of pulmonary lesions in cattle for slaughter in the Municipality of Mossoró, RN

Aimed to investigate the main pulmonary changes found in cattle intended for slaughter slaughtering and industrial Refrigerator Natal, RN, from October 2013 to January 2014. Inspection was performed post mortem advocated by Regulation inspection of products of animal origin 2386 animal animals were divided into two groups: the coming Mossoro or from other states. Data were collected through records and analyzed using descriptive statistics (percentage) and frequency of variables found by chi square test. The results showed that 71 % (n = 1695) examined the lungs were considered healthy and 29 % ( n = 691) had some type of injury . Furthermore, 48.7 % (n = 337) of the convictions were of animals from Mossley and 51.3 % (n = 354) from other states . With regard to pulmonary disorders , emphysema (28.8 %) , congestion (28 %) , aspiration of blood ( 12.3 %), pneumonia (8.8%) , aspiration of rumen contents (8 %) , hyperemia were observed ( 8%), abscess (2.7%) , edema (2.4%) and pneumonia (1.0%). Both groups showed similar results when compared to each other, except for abscess (p = 0.02) and agonal aspiration of blood ( p = 0.00 ) in the animals of the region of Natal, edema (p = 0.04) and emphysema ( p = 0.03 ) for animals from other regions of the country. It was concluded that animal stunning at slaughter is important, influencing the appearance of pulmonary changes, being related to a standard of efficiency, adequacy and accuracy training on stunning and people involved in the process.

The morphology of the pineal gland of the yellow-toothed cavy (Galea Spixii Wagler, 1831) and red-rumped agouti (Dasyprocta leporina linnaeus, 1758).

The pineal gland is an endocrine gland found in all mammals. This article describes the morphology of this important gland in two species of Caviideae, namely the yellow‐toothed cavy and the red‐rumped agouti. Ten adult animals of the two species used in current analysis were retrieved from the Center for the Multiplication of Wild Animals (CEMAS/UFERSA) and euthanized. The glands were removed and photographed in situ and ex situ. They were fixed in a paraformaldehyde solution 4% or glutaraldehyde 2.5% solution and submitted to routine histological techniques respectively for light and scanning electron microscopy. Macroscopically, the pineal gland with its elongated structure may be found between the cerebral hemispheres facing the rostral colliculi. Microscopically, pinealocytes and some glia cells were predominant. Contrastingly, to the cavys pineal gland, a capsule covered the organ in the agouti, with the emission of incomplete septa to the interior, which divided it into two lobules. Light and scanning electron microscopes failed to show calcareous concretions in the pineal gland. Based on the topography of the cavys and agoutis pineal gland, it may be classified as supra‐callosum and ABC type. Microsc. Res. Tech. 78:660–666, 2015.

Avaliação do perfil eritrocitário de jumentos nordestinos (Equus asinus) suplementados com hematínico a base de vitaminas, sais minerais e glicose

Este trabalho avaliou as alteracoes causadas pela administracao diaria de um hematinico a base de vitaminas do complexo B e K, cobre, cobalto, zinco, ferro e glicose no perfil eritrocitario de asininos da raca Nordestina. Para tanto, foram utilizados oito asininos, que durante 35 dias permaneceram estabulados recebendo alimentacao balanceada e agua a vontade, alem do suplemento em questao. Os parâmetros analisados foram hematocrito, numero de hemacias, concentracao de hemoglobina, volume corpuscular medio, concentracao de hemoglobina corpuscular media, como tambem a observacao das celulas vermelhas, atraves de esfregaco sanguineo. O hematocrito, hemacias, concentracao de hemoglobina, VCM e CHCM demonstraram aumento significativo apos a utilizacao do composto, porem nao foram observadas alteracoes nas analises dos esfregacos. O suplemento, ao termino do experimento, foi capaz de melhorar o perfil eritrocitario dos animais.
