The present study would identify the toxic effect of lactational exposure to low level of TCDD on mice offspring by observing body weight, thymus and spleen development, the histological changes and expression of cytochrome P450 1A1 enzyme (CYP1A1), apoptosis gene B-Cell lymphoma/leukemia 2 (Bcl-2) and Bcl-associated x protein (Bax) in thymua and spleen tissue.
