Документ Morphological features of the liver parenchyma in the experimental supplementation of ration with the food additives(Aluna Publishing, 2022-07) Mustafina, H. M.; Starchenko, I. I.; Fylenko, B. М.; Koka, V. М.; Cherniak, V. V.; Roiko, N. V.; Proskurnya, S. A.; Мустафіна, Галія Міркатівна; Старченко, Іван Іванович; Филенко, Борис Миколайович; Кока, Володимир Миколайович; Черняк, Валентина Володимирівна; Ройко, Наталія Віталіївна; Проскурня, Сергій АнатолійовичThe aim: The aim of the paper was the experimental study of the morphological features of albino rat hepatocytes after the consumption of the complex of food additives (monosodium glutamate, sodium nitrite, Ponceau 4R) supplemented into the ration and consumed for four weeks. Materials and methods: The study was performed on 30 outbred albino rats of both genders, weighing 204±0.67 g. The ration of the experimental animals, supplemented with a combination of food additives, namely, monosodium glutamate, Ponceau 4R, sodium nitrate, was consumed for 1 and 4 weeks. The study of the structure of hepathocytes was carried out on traditional histological preparations and preparations stained with Best’s carmine. Results: Supplementation of ration with the complex of food additives for one week showed the phenomena of fatty degeneration that dominated in hepatocytes, and in a longer consumption of food additives in the ration (for four weeks), the number of liver cells with the phenomena of hydropic degeneration significantly increased, while individual hepatocytes had signs of irreversible destructive changes. Conclusions: Consumption of the complex of food additives supplemented into the standard ration of laboratory animals for 4 weeks leads to a significant change in the dimensions of the liver cells, a decrease in their glycogen content, and a progressive increase in the number of hepatocytes with alterations.Документ Morphological features of the stromal component of the liver in experimental supplement of rations with food additives(Полтавський державний медичний університет, 2022) Mustafina, Н. M.; Starchenko, I. I.; Koka, V. М.; Fylenko, B. М.; Roiko, N. V.; Cherniak, V. V.; Prylutskyi, O. K.; Мустафіна, Галія Міркатівна; Старченко, Іван Іванович; Кока, Володимир Миколайович; Филенко, Борис Миколайович; Ройко, Наталія Віталіївна; Черняк, Валентина Володимирівна; Прилуцький, Олексій КостянтиновичThe purpose of this study was to study in an experiment the morphological features of the structural organization of the periportal connective tissue of the liver of white rats after the introduction into the diet of a complex of food additives (sodium glutamate, sodium nitrite, Ponceau 4R) for 8 weeks. The study was performed on 30 outbred white rats of both sexes, weighing 204 ±0.67 g. The experimental animals were additionally fed a combination of food additives – monosodium glutamate, Ponceau R-4, sodium nitrate for 1 and 8 weeks. The study of the stromal component of the liver was carried out on traditional histological preparations. To differentiate immunocompetent cells of connective tissue structures, immunohistochemical reactions with antibodies to CD68 and CD3 were performed. It was established that the addition of a complex of food additives (sodium glutamate, sodium nitrite, ponzo 4R) to the standard diet of laboratory animals for 8 weeks leads to excessive development of connective tissue in the liver and changes in the relative number of CD3+ and CD68+ cellular elements.
