Cases of folliculogenesis in the rat’s thyroid gland in norm and under experimental conditions

Objective: identification and characterization of the stages of formation of new follicles, as well as the frequency of folliculogenesis in various parts of the thyroid gland in the norm and in the experiment. Material and methods. The experiment was carried out on 36 mature white rats divided into three groups: control (I), 60-day exposure to sodium benzoate at a dose of 1000 mg/kg (II) and administration of mexidol at a dose of 50 mg/kg against the background of 60-day administration sodium benzoate (III). The stages of folliculogenesis were studied using light microscopy followed by a statistical analysis of its frequency.
