Abstract


This study was conducted in a postgraduate labs in college of veterinary Medicine in Al-Muthanna University to investigated the comparative histological , histochemical and scanning electron structure of the lung in male mynah and starling birds . Twelve individuals' birds (6 mynah and 6 starling birds) were subdivided into groups (8 birds for histological and histochemical study) and (4 birds for scanning electron examination). The histological and histochemical study were carried out by Routine Histological Technique and Histochemistry analysis. Histological Results showed that the lungs of both mynah and starling had distinct characteristics. The histological sections of the lungs of both birds reveals the absence of a pleura. The lung tissue is composed of numerous lobules that are separated by trabeculae. The lungs are composed of secondary bronchi, para bronchi, atria, infundibula and air capillaries, all lined with simple squamous epithelium. The histochemical results of lungs in both birds revealed positive response to Masson's trichrome stain, indicating the existence of connective tissue. Conversely, a positive response to van Gieson's stain suggests the presence of collagen fibers that are stained red. The elastic inter-parabronchial septa of mynah birds and the outer wall of the lung of the starling bird are observed using scanning electron microscopy.
