Monosodium glutamate is one of the most common dietary supplements (E621), approved for use in many countries worldwide, and is considered relatively safe. However, numerous scientific studies have reported various toxiceffects of food additive E621 on organs and tissues, manifested in structural organization and dysfunction changes.The effect of monosodium glutamate, particularly on the structure of blood vessels, requires further study, given the
sometimes contradictory available data in the scientific literature and its prevalent, virtually uncontrolled use. Thisstudy aimed to analyze the morphological changes of the carotid sinus in the early stages of exposure to monosodium glutamate when administered orally in the experiment. The carotid sinus area of 10 laboratory white male rats,which received sodium glutamate orally at a dose of 10 mg/kg/day for four weeks, was studied by morphological
methods at the macro- and microstructural levels. The obtained data are compared with the results of a morphological examination of the same area in 10 animals of the control group. In the early stages, regular consumptionof sodium glutamate may be associated with changes in the structural organization of the carotid sinus, the morphology of the carotid glomus, and the structure of the carotid artery wall, which can lead to cerebral circulatory disorders and functional changes in the carotid glomus. Further study requires the degree of morphological changes with prolonged consumption of monosodium glutamate and features of the structural organization of the sinus in the conditions of its withdrawal.
