Radial alveolar count as a tool for the estimation of fetal age. Betz P1, Nerlich A, Bussler J, Hausmann R, Eisenmenger W.
Explanation:The radial alveolar count method of Emery and Mithal has been re-evaluated on 76 normal postnatal lungs. Results of reproducibility assessments suggest that. --------------------------------------------------Note added at 9 mins (2012-03-16 22:05:16 GMT)--------------------------------------------------Lung weight: body weight ratios (LW:BW) were calculated, and morphometry was determined by the radial alveolar count (RAC) (Emery and Mithal, 1960).
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 maturation. Values lower than 2. 0 could only be found in lungs of fetuses aged less than 18 weeks. Between 18 and 25 weeks of gestation, relatively constant levels of RAC were observed but with considerable interindividual variation.
Radial alveolar counts. Radial alveolar counts (RAC) were performed on hematoxylin and eosin-stained tissue sections from conditionally targeted (n = 7) and littermate control (n = 8) mice at 8 weeks of age. There is a significant 17% reduction in the number of alveoli in conditionally targeted mice (mean number of 8. 2 vs. 9. 9, p = 0.
