title: [Possible difference in elastin content between the right and left lung in rats].
abstract: Elastin and collagen were measured on separate right and left lungs of rats, within two age-groups : 3 months and 8-15 months. The elastin content was significantly higher in the left series. An explanation based upon the bronchovascular density was tested and the results suggest a difference in regard to the development of the parenchyma surrounding the left bronchovascular tree. The knowledge of such peculiarities, if they are confirmed, may help understanding the structural basis of function, by the means of separate tests of mechanical properties.
