Macroscopic changes of the cats liver during diseases

The main and most accessible part of pathomorphological research is the macroscopic method, which makes it possible to effectively diagnose various animal diseases. Changes in the liver, as an organ involved in the process of digestion and metabolic reactions, are important in examining the pathogenesis and diagnosis of diseases. A macroscopic study of the liver of 15 cats with various diseases was performed. Among the animals subjected to a pathoanatomic autopsy there were 9 cats and 6 cats, from 2.5 months to 18 years old. The most common changes were liver dystrophy: protein, fat, protein-fat, which were registered in many diseases. The main diseases diagnosed at the autopsy were infectious cat peritonitis, dipylidiosis, liver lipidosis, dis eases of the digestive canal and kidneys, and bone tumors of the lower jaw. Alterative hepatitis was observed in an animal with infectious cat peritonitis. This disease was also accompanied by fibrinous perihepatitis. Cysts in the liver were observed with a similar lesion of the kidneys. The mechanisms of development of identified dystrophies are infiltration of substances entering the liver with blood, and decomposition - the breakdown of complex chemical compounds. Fibrinous perihepatitis is associated with the activity of macrophages that cause high permeability of the wall of small blood vessels, which makes it possible for large fibrinogen molecules to pass through, followed by the formation and accumulation of fibrin. Alterative hepatitis with numerous small foci of necrosis is obviously also associated with the activity of these inflammatory cells. Liver cysts, combined with similar changes in the cortical layer of the kidneys, and in one case, the mucous membrane of the bladder, indicate the innate nature of this pathology
