Hiperplasia em túnicas de artérias coronárias de beijupirás criados em sistema offshore

Abstract: RESUMOAs lesões coronarianas já foram relatadas em espécies de peixes anádromos, com características semelhantes às observadas em aterosclerose humana, mas não em peixes cultivados sem interferência de padrões reprodutivos. Objetivou-se descrever lesões coronarianas em beijupirá (Rachycentron canadum) criado em sistema offshore, em 54 exemplares coletados ao longo do cultivo de oito meses. Amostras de tecido cardíaco de alevinos e juvenis foram submetidas à análise histopatológica e à microscopia eletrônica de… Show more

“…The coronary artery hyperplasia in beijupirá (Rachycentron canadum, Linnaeus, 1766) was reported from our laboratory [16]. The present work aimed to establish the relationship between tunics and luminal obstruction through morphometry, evaluating the thickening of the tunic during from offshore cultivation period, with the growth of the animal.…”

“…The specimens of beijupira were obtained from offshore cultivation situated 5 km away from the coast, in the state of Pernambuco/Brazil, for seven months of farming. The animals were transported alive under constant aeration and renovation of water to the port of Recife/PE [16], where sedation was carried out followed by euthanasia, by immersion in benzocaine hydrochloride (p-Aminobenzoic acid ethyl ester) [17]. Then, the fish were subjected to external examination and necropsy with left side opening and heart samples collection for histopathological and morphometric examination [18].…”

“…Embora qualquer artéria possa ser afetada, os principais alvos são as artérias aorta, as artérias coronárias e cerebrais, tendo como principais consequências o infarto do miocárdio, a isquemia cerebral e o aneurisma aórtico 11 .…”

“…Quando o endotélio vascular perde a capacidade de manter um equilíbrio entre as túnicas, a camada íntima fica exposta e doenças evoluem, provocando um espessamento da camada média, desencadeando uma série de alterações fisiológicas que podem refletir em lesões vasculares, com possível aumento de pressão arterial 11 .…”
