MORPHOLOGICAL FEATURES OF THE SPLEEN IN RATS DURING EARLY POSTNATAL ONTOGENESIS UNDER MATERNAL EXPOSURE TO FIPRONIL

The spleen is one of the key organs of the immune system, playing an important role in the formation of immune status in mammals [2–5]. A number of studies describe the morphological structure of the spleen in adult animals under normal conditions and under acute toxic exposure to pesticides. However, the morphological features of the spleen during postnatal development under chronic exposure to fipronil through the maternal organism remain insufficiently studied [1,6–10].
