HISTOLOGIC FEATURES OF THE DOG'S MAMMARY GLANDS BLOOD SUPPLY

Abstract

The purpose of this study was to establish and characterize the kinds and types of blood vessels micro-circulation from parenchyma of the dog's mammary glands. The incoming blood vessels in mammary complexes and their branches in inter- and perilobular connective tissue septs, as so the following smaller blood vessels in glandular parenchyma were investigated. These vessels presented on histological slides from bitches’ mammary gland in diestrous cycle were obtained and prepared by conventional histological method and was observed. The samples were fixed in solution 10 % neutral formaldehyde, then cut by microtome at 7 μm and stained with Hematoxylin and Eosin. Myotypical arteries and arterioles in specific position as rosette were established in mammary teats and postarteriolar capillaries as so venules and small myotypical veins in inter- and perilobular connective tissue septs were observed. Capillaries decrease their number in correlation of glandular parenchyma involution. The established blood vessels morphologic features in bitches’ mammary glands are important for glandular functional characteristic in norm and as so frequently happened pathological conditions, especially in mastitis and neoplasms.
