TAILIEUCHUNG - Micrometrical studies of bronchi and bronchiole in prenatal gaddi (Breed) sheep lung

The present study was conducted to investigate various micrometric parameters of bronchiole and bronchi in prenatal Gaddi sheep lung. A total of n=18 Gaddi sheep fetuses were collected from various slaughter houses in and around Palampur town for one year. The prenatal lung samples were divided into three groups which included group-I (0-50 days of gestation), group-II (50-100 days of gestation) and group-III (100-150 days of gestation) based on their age in days. The overall diameter of bronchiole increased from group-I to group-III. However, the diameter of bronchi decreased significantly in right apical, left apical and left cardiac lobe but it increased significantly in right cardiac and left diaphragmatic lobe from group-II to group-III. The epithelial height of bronchiole decreased from group-II to group-III in left apical and right diaphragmatic lobes. While, the height of nucleus of bronchiole decreased significantly from group-II to group-III in left apical, left cardiac and left diaphragmatic lobes. The epithelial height of bronchi decreased significantly from group-II to group-III in apical and accessory lobes of right lung. However, the nucleus height of bronchi decreased significantly from group-II to group-III in right apical and right diaphragmatic lobes. | Micrometrical studies of bronchi and bronchiole in prenatal gaddi (Breed) sheep lung
