“…situa--se ventralmente ao atlas e áxis (Bertassoli et al 2013) enquanto na Dasyprocta sp. posiciona-se na região cervical caudal devido ao maior comprimento da língua (Silva et al 2014). Enquadrou-se, portanto, na generalização de que a esqueletopia da laringe dos mamíferos terrestres se estende desde a base do occipital ou primeiras vértebras cervicais até o nível da terceira ou quarta vértebras cervicais (Harrison 1995).…”

“…Em Dasyprocta sp. a cricoide foi a mais ampla das cartilagens (Silva et al 2014). Aliado a isto, a articulação do tipo sinovial entre as cartilagens tireoide e cricoide revela que a laringe de C. thous é uma estrutura típica de espécies mamíferas mais recentes (Harrison 1995).…”

“…Um processo degenerativo que leve à calcificação seguida de ossificação em partes das cartilagens hialinas da laringe é relatado como relacionado ao envelhecimento em seres humanos (Hately et al 1965) e animais domésticos, especialmente no equino (König & Liebich 2011). Também foi encontrada na cartilagem cricoide de indivíduos machos de Dasyprocta sp., ainda que a idade não fosse relatada na metodologia (Silva et al 2014).…”

Resumo: Cerdocyon thous (cachorro-do-mato) é o canídeo silvestre mais comum em território sul-americano. Objetivou-se com o presente trabalho descrever a morfologia macroscópica, microscópica e comparada da laringe nesta espécie. Para tal, as laringes de dezesseis espécimes (quatro machos e doze fêmeas) foram analisadas quanto à topografia, forma, morfometria, musculatura intrínseca e histologia. A laringe dispôs-se ventralmente ao áxis e foi constituída por uma cartilagem tireoide e outra cricoide (hialinas), uma epiglótica (elástica) e um par de ariteoides (mistas). Um par de cartilagens sesamoides foi identificado entre os processos corniculados e a lâmina da cricoide. A morfometria revelou que a tireoide é a maior cartilagem. Não houve sinais definitivos de dimorfismo sexual na laringe de C. thous. O epitélio predominante foi do tipo pavimentoso estratificado o qual sofreu transição para pseudoestratificado cilíndrico ciliado ao nível do terço caudal da tireoide e rostral da cricoide. A laringe de C. thous mostrou semelhança com a do cão doméstico, ainda que o formato das cartilagens tenha apresentado diferenças.

“…This animal is being a rich source of protein and hunting target in the region, but is not on the list of endangered animals (BRASIL, 2016). In this way, its production in captivity is expanding, since several research groups are developing studies on its morphology, ultrasonographic and echocardiographic evaluation, as well as a biological model for alternative treatments of chronic diseases (CABRAL et al, 2012 ;CARVALHO et al, 2015 ;DINIZ et al, 2013 ;FORTES et al, 2013;SILVA et al 2014 ;SOUSA et al, 2013). Blood is responsible for transporting and micronutrient elements related to metabolism and thus its analysis reflects the physiological situation of individual.…”

ABSTRACT:The aim of this estudy was to establish the levels of serum total protein, albumin, globulin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), calcium, phosphorus, urea, creatinine, bilirubin and glucose during pregnancy in agoutis. Animals: Twelve pregnant agouti from the Center for the Study and Preservation of Wild Animals (CSPWA) of the Federal University of Piauí (UFPI) were used in this research. After identification of the estrus, the day of the coverage was confirmed by means of vaginal cytology with the visualization of spermatozoa (day zero) and confirmation of pregnancy by ultrasonographic examination after 15 days. Blood samples were collected by lateral saphenous vein puncture after physical restraint, every 10 days until the end of pregnancy, for biochemical analyzes. A completely randomized experimental design was used and the means compared by the Duncan test at 5% probability using the SAS (Statistical Analysis System). The results of the biochemical analysis of total protein, albumin, globulin, urea, creatinine, calcium, phosphorus, serum ALT, glucose, AST, total bilirubin, direct bilirubin and indirect bilirubin in pregnant agouti (Dasyprocta prymnolopha) did not differ when compared to nonpregnant females. The serum biochemical levels during pregnancy in agoutis, except for calcium and phosphorus, were unchanged compared to those found in the non-pregnant adult animal, as occurs in other species. The changes during pregnancy reflect the physiology and biology of wild species, elucidating information about the biochemical parameters during pregnancy, thus characterizing the animal as a benchmark for comparisons with other species, extolling its importance both for nature conservation and production in capivity.

Armadillos, Xenarthras representatives, known for adaptability to different ecosystems, own specific morphophysiological characteristics that are not known and deserve to be studied. The aim of this study was to describe the morphology of cartilage of the larynx of the nine-banded armadillo (Dasypus novemcinctus). Five dead armadillos were donated by the Chico Mendes Institute of Biodiversity (ICMBio-PI) to the Federal University of Piauí. The animals were fixed and dissected for removal of the larynx. The cartilages were identified and described, photodocumented, and schematized. Fragments with about 0.5 cm of each cartilage were collected and submitted to classical histology for Hematoxylin-Eosin coloring. The slides were assembled in enterlan and analyzed under a light microscope. The larynx of the armadillo (D. novemcinctus) is located in the mentonian region, ventral to the esophagus, and due to the total positioning of the tongue in the oral cavity, there is also a cranial cervical position in this species. The larynx has five cartilages, they are: a cricoid, a thyroid, an epiglottis, and two arytenoids. The corniculate process is present; however, the cuneiform process is absent. The epiglottis has a discrete bifurcation at its apex. In all cartilages epithelial variations are observed. The tissues are varied from squamoso stratified to cylindrical pseudostratified, with propria lamina rich in mucoserosas glands. With the exception of epiglottic cartilage, predominantly elastic, the rest are hyaline. The larynx of D. novemcinctus, although the same number of cartilages, differs morphologically and microscopically from the larynx of other species.
