Biometry and histom~rphometry,of prenatal lung' in Indian buffalo

Abstract

Biometrical and histomorphometrical studies were conducted on lungs of 17 Indian buffalo fetuses ranging from 3.8 em to 110.6 cm crown rump length (CRL). The foetuses were divided into 3 groups based on their CRL. Gross morphological features oflungs were distinct by 10.1 cm CRL. The weight and volume ofboth the lungs increased with concominant increase in CRL. Micrometrical observations revealed that epithelial height decreased, whereas thickness ofarterial wall and bronchial cartilage increased with increase in CRL. The thickness ofinterlobular septa and bronchiolar diameter decreased with increase in CRL.
