xperimental autoimmune prostatitis (EAP) is an experimental model of autoimmune disease, developed in Wistar rats against prostatic components. The 12-and 18-month-old rats with EAP show a higher cellular autoimmune response and lower humoral autoimmune response compared to 3-month-old rats. The analysis of NO· and O2 production by peritoneal exudate cells (PECs) resulted in a higher NO· and O2 production in EAP rats at all ages, compared to control animals. PECs from 12- and 18-month-old rats produced more NO· and less O2 than PECs from 3-month-old rats. However, lipopolysacharide (LPS) did not stimulate PECs from aged rats for NO· production as much as in 3-month-old rats and thus, turning out in a lower index of LPS-stimulation of PECs from aged rats, compared to 3-month-old rats. Furthermore, the mast cells number in prostates of EAP rats, especially the number of degranulated cells, was higher than in control animals, but no significant differences were found bet
