Resumo: Sloths of the genus Bradypus have been suffering considerably from anthropic pressure, which highlights the importance of knowing the peculiarities of these animals. Therefore, a detailed analysis of the heart of the species Bradypus variegatus was performed. To identify the macroscopic, topographic, biometric and vascular characteristics of the organ, dissections and measurements of 15 cadavers and digital chest radiographs of four healthy animals were performed. In order to clearly observe the coronary profile of B. variegatus, three specimens received an arterial injection of latex with red pigment, and in one of them, an intravenous injection, in blue, was also performed. For the microscopic description, the hearts of four specimens were used. Organs were fixed in 10% buffered formaldehyde with 0.01M sodium phosphate buffer (PBS) at pH 7.3 and subjected to paraffin embedding processing, followed by 4μm thick sagittal sections stained in hematoxylin-eosin. Electrocardiographic profiles of five sloth animals in good health were also obtained. In view of the collected results, the heart of the species in question is conical, located obliquely in the middle mediastinum, displaced to the left, presenting varied skeletonpies. The organ is covered by the pericardium and the atria are internally, predominantly smooth, while pectineal muscles are seen in the atria. The ventricles have fleshy trabeculae and papillary muscles, from which tendinous chords depart, which attach to the valves. Two coronary arteries, one right and one left, were described. According to the histopathological findings, necrosis of different cell types was seen in the hearts. Endocardiosis and inflammatory and degenerative, processes have also been described, with a lower prevalence. Based on electrocardiographic recordings, sloth animals demonstrated sinus rhythm, with heart rate between 67 and 100bpm. In general, the heart of B. variegatus does not show large discrepancies in relation to other quadrupeds.

Sendo assim, realizou-se uma análise detalhada do coração da espécie Bradypus variegatus. Para identificar as características macroscópicas, topográficas, biométricas e vasculares do órgão, efetuaram-se dissecações e mensurações de 15 cadáveres e radiografias digitais do tórax de quatro animais saudáveis. A fim de se observar claramente o perfil coronariano de B. variegatus, três espécimes receberam a injeção arterial de látex com pigmento vermelho, e em um deles, também se fez a injeção venosa, em azul. Para a descrição microscópica, utilizou-se os corações de quatro espécimes. Os órgãos foram fixados em formaldeído tamponado a 10% com tampão fosfato de sódio (PBS) 0,01M e pH de 7,3 e submetidos ao processamento de inclusão em parafina, seguindo-se com os cortes sagitais de 4μm de espessura, corados em hematoxilina-eosina. Foram ainda obtidos, perfis eletrocardiográficos de cinco bichos-preguiça com boa saúde. Diante dos resultados coletados, o coração da espécie em questão é cônico, situado obliquamente no mediastino médio, deslocado para a esquerda, apresentando esqueletopias variadas. O órgão é revestido pelo pericárdio e os átrios são internamente, predominantemente lisos, enquanto que nas aurículas são observados músculos pectíneos. Os ventrículos possuem trabéculas cárneas e músculos papilares, dos quais partem cordas tendíneas, que se prendem as válvulas. Foram descritas duas artérias coronárias, uma direita e uma esquerda. De acordo com os achados histopatológicos, nos corações foram visualizadas necroses de diferentes tipos celulares. Endocardiose e processos, inflamatório e degenerativo também foram descritos, com menor prevalência. Com base nos registros eletrocardiográficos, os bichos-preguiça demonstraram ritmo sinusal, com a frequência cardíaca entre 67 e 100bpm. De modo geral, o coração de B. variegatus não apresenta grandes discrepâncias em relação aos demais quadrúpedes.Submitted by (ana.araujo@ufrpe.br) on 2024-07-22T13:17:37Z No. of bitstreams: 1 Priscilla Virginio de Albuquerque.pdf: 11272631 bytes, checksum: 233c2e7555a250d9768a1b2aa91e8324 (MD5)Made available in DSpace on 2024-07-22T13:17:37Z (GMT).
