A Study On Paranal Sinus Micromorphometrical Parameters In Dogs Of Different Ages, Ivaylo Stefanov
A Study On Paranal Sinus Micromorphometrical Parameters In Dogs Of Different Ages, Ivaylo Stefanov
Turkish Journal of Veterinary & Animal Sciences
This study determines the micromorphometric parameters of the main structural elements of the paranal sinus in male (n = 20) and female (n = 8) mongrel dogs of different ages. Pieces of about 1 cm3 were obtained from different parts of the organ and put in 10% neutral formalin. The tissue samples were further used for the preparation of paraffin sections that were stained with hematoxylin-eosin for light microscopy measurements. In the sinus wall, the thickness of the epithelium was measured, as was that of the subepithelial and subglandular connective tissue layers, the zona with the apocrine glands, and the …

Morphological Characterization Of The Immune Organs In Ostrich Chicks, Hui Song, Ke-Mei Peng, Sheng-He Li, Yan Wang, Lan Wei, Li Tang
Turkish Journal of Veterinary & Animal Sciences
This study describes the anatomical, light microscopic, and ultrastructural characterization of the immune organs in ostrich chicks. In this study 6 healthy 8-week-old ostrich chicks were processed for light and transmission electron microscopy. Hematoxylin and eosin as well as improved Weigert staining were used for light microscopy. The small thymus, which clustered caudally along both sides of the neck, contained Hassall's corpuscles in the medulla. The cloacal bursa, which formed the hanging and lateral walls of the cloaca, enveloped the cloaca but did not form a truly independent bursa. Inside the bursa convex papillae were densely distributed on the surface …
