Title in Portuguese
Modelo experimental de indução de enfisema pulmonar por exposição à fumaça de cigarro.
Keywords in Portuguese
Doença pulmonar obstrutiva crônica
Enfisema pulmonar
Fumo
Ratos
Tabagismo
Abstract in Portuguese
A Doença Pulmonar Obstrutiva Crônica (DPOC) destaca-se como um grave problema de saúde no mundo. O enfisema pulmonar, dentro do espectro das DPOC, caracteriza-se pelo alargamento dos espaços aéreos distais resultante da destruição do parênquima pulmonar. O tabagismo é considerado o principal fator relacionado ao surgimento da patologia. Considerando a escassez de aparelhos comercializados para exposição à fumaça de cigarro, bem como o elevado custo dos existentes, o presente projeto propôs um modelo experimental de enfisema por exposição à fumaça utilizando um novo aparato. Foram realizadas avaliações morfométricas e funcionais nos pulmões de ratos expostos à fumaça ou ao ar ambiente. Além disso, o peso dos animais foi aferido semanalmente. Os resultados indicaram alargamento dos espaços aéreos pulmonares, além de redução do ganho de peso nos animais expostos. Não houve diferenças funcionais entre os grupos controle e experimental. O trabalho objetivou o desenvolvimento de um aparato eficiente e menos custoso para estudos relacionados ao enfisema pulmonar.

Abstract in English
The Chronic Obstructive Pulmonary Disease (COPD) stands out as a serious health problem in the world. The pulmonary emphysema, in the spectrum of COPD, has as main feature the enlargement of the airspaces distal resulting from destruction of lung parenchyma. Smoking is considered the main factor related to the development of pathology. Considering the lack of machines marketed for exposure to cigarette smoke, as well as the high cost of devices available, the currently project has proposed a experimental model of pulmonary emphysema induced by the use of a new apparatus. Were performed morphometric and functional measurements in the lung of rats exposed to cigarette smoke or clean air. Further, the animal weight was measured weekly. The results indicated enlargement of the pulmonary airspaces, as well as reduction of weight gain in animals exposed. There were no functional differences between control and experimental groups. The current study aimed to the development of an efficient and less costly apparatus for experimental studies related to the pulmonary emphysema.
