Segmentação bronquicopulmonar e análise microscópica da árvore brônquica em Quatis

Abstract

The coati (Nasua nasua) is a carnivore belonging to the Procyonidae family that inhabits the entire South American continent. Due to the lack of studies related to anatomical-surgical segmentation and the morphology of the bronchial tree, the objective of this work was to characterize the bronchial tree macro and microscopically for future comparisons in other studies with wild animals. For this work, four euthanized animals (coatis) were used, from CECRIMPAS / UNIFEOB- IBAMA 02027.003731 / 04-76. The bronchiopulmonary segments were identified according to their position pattern in relation to the pulmonary lobe, and the microscopic analysis of the bronchial tree was performed using a routine H.E (hematoxylin / eosin) staining technique. In the lungs of the coatis, 24 bronchiopulmonary segments were found: four in the left cranial lobe; five in the left caudal lobe; three in the right cranial lobe; three in the right middle lobe; four in the right accessory lobe and five in the right caudal lobe. It was found in this work that the lobation of the lungs of coatis are similar to that of domestic carnivores and that microscopically the bronchial tree of coatis is similar to that of the other mammals described in the literature consulted, with great variations in its architecture according to the bronchial tree. branches, decreasing in diameter and thickness of its walls.
