To the question about the state of the liver of a parrot corella under exposure to a toxic agent

Abstract

The liver is the main detoxification organ in the body of both animals and birds. When exposed to any external toxic agent, hepatocytes are damaged. Objective: to study the morphological state of the liver of a cockatiel parrot when exposed to a toxic agent. Materials and methods of research: The research was carried out at the Department of Anatomy and Physiology of the State Agrarian University of the Northern Trans-Urals. The objects of research were the corpses of cockatiel parrots, aged 3-5 years. Under the action of the toxic agent, a light brown liver staining with red stripes was noted. The consistency of the organ is loose, easily torn. Parrot liver mass is increased. A histological study of the structure of the structures of the liver of a parrot revealed that the veins of the central, portal and sinusoidal capillaries are not filled with blood, they are dilated. The structure of the hepatic lobules and most of the hepatocytes is impaired. As a result of the studies, it was found that when exposed to an endogenous toxic agent, serious morphological changes occur in the liver, which is manifested by the development of toxic hepatitis with massive necrosis of hepatocytes.
