title: Aryl hydrocarbon (benzo[a]pyrene) hydroxylase in guinea pig lymphoid tissue.
abstract: Aryl hydrocarbon hydroxylase (AHH) activity was detected in a variety of guinea pig lymphoid tissues and was increased by intradermal or ip administration of 3-methylcholanthrene AHH levels were generally greater in spleen than in lymph node, bone marrow, or thymus. Similar AHH activities were observed in lymphoid tissues from Sewall-Wright inbred strain 2 and strain 13 guinea pigs. Greater AHH activities were associated with peritoneal and alveolar macrophages than with lymph nodes lymphocytes in the absence of mitogens.
