A macroanatomic study on lung vessels in hasak sheep

Özüdoǧru, Zekeriya ( Aksaray, Yazar )The aim of this study was to investigate the macroanatomical examination of lung vessels in Hasak sheep. In this study, 8 Hasak sheep lungs from Konya Bahri Dağdaş International Agricultural Research Institute, Unit of Experimental Animals Unit were used. Corrosion casting technique and latex injection were applied to the materials. Corrosion casting technique and latex injection materials were photographed and presented in the study. The lungs were found to be wrapped with pleura visceralis (pleura pulmonalis) in the cavum thoracis. The venae pulmonales, carrying the clean blood to the heart, left the lobes of the lung. Later, cranial root was formed by the merger of the v. pulmonalis lobi cranialis dextri ve v. pulmonalis lobi medii and also caudal root was formed by the merger of the v. pulmonalis lobi caudalis dextri, ramus lobi accessorii, v. pulmonalis lobi cranialis sinistri and v. pulmonalis lobi caudalis sinistri. These two roots were opened to the atrium sinister. It was observed that truncus pulmonalis (arteria pulmonalis) was a vessel that carries the venous blood in the right ventricle to the lungs and 3 semilunar valvula found in its origin. Truncus pulmonalis ended with divided of a. pulmonalis dextra ve a. pulmonalis sinistra at the level of bifurcatio trachea. In this study, anatomical features of lung vessels and similarities and differences with other species were revealed

A morphological, morphometrical and histological investigation of the interdigital gland in Hasmer and Hasak sheep

*Özüdoǧru, Zekeriya ( Aksaray, Yazar )Background: The interdigital glands of sheep perform various functions including those pertaining to sexual behaviours. Morphological and histological structure of the gland demonstrates differences among species. The aim of this study is to examine the morphological and histological structure of Hasak and Hasmer sheep's interdigital glands and to determine the differences with other sheep breeds. Materials and methods: For this research, we selected 7 Hasak and 7 Hasmer female sheep. After scarification, the feet were obtained and used for anatomical and histological examinations. For the histological examination, the interdigital gland tissues were stained with Crossman modified triple, periodic acid Schiff (PAS) and Alcian blue (AB) staining. Results: The morphometric analysis results, mean values of weight, body length, body diameter, flexura, ductus length, ductus diameter, were observed as 0.80 mm, 14.61 mm, 5.98 mm, 5.62 mm, 26.58 mm, and 3.25 mm, respectively in Hasak and 0.8 mm, 15.46 mm, 6.37 mm, 5.70 mm, 24.52 mm, and 3.52 mm in Hasmer sheep. The histochemical staining revealed that the apocrine secretion of this gland was PAS positive and AB negative. Conclusions: The weight, body length, body diameter, flexura, ductus length and ductus diameter in the forefoot's interdigital glands of both Hasak and Hasmer sheep were higher in a statistically significant manner than those of the hindfeet's glands
