There are several parameters employed to evaluate lung growth or development in
biopsies. The simplest method is the radial alveolar count (RAC), which is the number of …

The radial count method of Emery and Mithal was applied to the lungs of 37 infants of
gestational age 19-42 weeks. The method could be used satisfactorily to evaluate airspace …

A total of 53 normal fetuses with a gestational age ranging from 15 up to 39 weeks was
investigated and the radial alveolar count (RAC) was estimated as a parameter for lung …

In a recent issue of the European Respiratory Journal, HIND AND MADEN [1] reported a
series of well-designed experiments conducted to further enlighten the role of retinoic acid in …

Lung morphometry was introduced over 50 years ago to provide quantitative evaluation of
the lung structure. The existing parameters, such as mean linear intercept and destructive …

Aging is associated with changes in the structure and function of the lung that may increase
susceptibility to chronic lung diseases. The aim of this study was the morphometric …

The aging process causes anatomical changes in the lungs, as well as a reduction in
function. Some pulmonary metrics change depending on the species and strain. The mouse …

We studied the volumetric fraction of the respiratory portion (respiratory bronchioli, alveolar
ducts, alveolar sacs and alveoli) for nine autopsied lungs aging from the fourth day after birth …

INTRODUCTION: Oxygen exposure models in rodents have been shown to mimic important
features of human bronchopulmonary dysplasia (BPD). 1 However, the pathophysiology of …

Alveolar, the smallest structural and functional units within the respiratory system, play a
crucial role in maintaining lung function. Alveolar damage is a typical pathological hallmark …
