Summary: The work deals with the study of the detection possibility of the malignant tumors, particularly sarcoma C-180, in biological objects (mice) by applying a new contactless diagnostic method developed on the basis of acoustic modulation spectroscopy. The comparative analysis of registered amplitude-frequency acoustic spectra of the studied healthy and sick objects allows us to detect and determine the dissemination of malignant tumors.
Key words: Acoustic field modulation, malignant tumors, sarcoma of C-180 type, acoustic spectroscopy, anisotropy of tissues.
Summary: It is shown that a daily intake of MSG at a dose of 30 mg / kg body weight for 28 days led to increased glucose and glucose-6-phosphatase activity and reduced lactate and lactic-dehydrogenase activity at a constant level of glycogen in the rats’ liver, which may indicate metabolic changes in the glucose metabolism.
Key words: MSG, carbohydrate metabolism, liver, rats.
Summary: The features of the structure and catalysis of the enzyme glutathione peroxidase.
Key words: glutathione peroxidase, vitamin E, α-tocoferol, glutathione, lipid peroxidation, antioxidant.
