В работе исследовалось гистопатологическое состояние печёночной ткани у двух видов рыб - сазана и серебряного карася, обитающих в реках Араз (Аракс) и Арпачай. Всего выловлено 26 особей: из р. Араз - 14 особей, из них 8 сазанов и 6 карасей, а из р. Арпачай - 12 особей, по 6 каждого вида. Гистологическое изучение срезов проводили после окрашивания их гематоксилинэозином. Состояние печёночной ткани рыб, выловленных в р. Араз в целом соответствовало норме. Вместе с тем были отмечены следующие изменения - у сазанов отмечается накопление в гепатоцитах крахмала, застой крови в небольших сосудах (стагнация), у карася также отмечается накопление крахмала и стагнация и в одном случае - фибросис жёлчного канала. У рыб, выловленных из реки Арпачай: у сазана отмечаются незначительные явления застоя в кровеносных сосудах, наличие единичных мелано-макрофаговых центров и выпадение гемосидерина, накопление крахмала, некроз отдельных клеток или их групп, у карася - пикноз ядра и гидропическая вакуолизация, нарушение трабекулярной организации, ацентрическое расположение ядра, стагнация, умеренная гипертрофия гепатоцитов и накопление крахмала.

We have investigated the histopathological state of the liver tissue in two species of fish - carp and goldfish caught in rivers Araz (Araks) and Arpachay. The total catch included 26 fish: 14 from the Araz river (8 crucian carp and 6 goldfish) and 12 from the Arpachay river (6 fish of each species). Histological examination was carried out after staining the sections with haematoxylin and eosin. The state of the liver tissue of the fish caught in the Araz river was generally in line with the norm. At the same time, we have observed the following changes: studies of crucian carp show accumulation of starch in hepatocytes and congestion of blood in small blood vessels (stagnation), whereas the studies of goldfish indicate accumulation of starch as well as fibrosis of gallbladder channel (one case). In the fish caught from the Arpachay river we have observed the following: crucian carp are characterized by general stagnation in the small blood vessels (stagnation), the presence of single melanoma-macrophage centers and hemosiderin deposition, starch accumulation, necrosis of individual cells or groups of cells, whereas goldfish are characterized by pyknosis of nuclei and hydropic vacuolization, impaired trabecular organization, acentric location of the nucleus, stagnation, moderate hypertrophy of hepatocytes and starch accumulation.
