Morphometric study of the remaining lungs of rats submitted to lobectomy or bilobectomy

The present study has been carried out in order to analyse the morphometry of remaining lungs of rats bearing in mind the average weight and volume of these lungs. Forty-five female adults Rattus novergicus albinus, Wistar were utilized. The animals were divided into three groups. Group I was submitted to middle lobectony of the right lung. Group II was submitted to upper and middle bilobectomy of the right lung and the control group did not undergo operation. The groups were subdivided into subgroups for post operatory evaluation at 30 and 60 days. The comparison between the groups operated on and the comparison between these two groups with the control group did not show major differences regarding average weight and volume of the lungs.
