mortality/aging
• over 50% of mice die within 2-3 weeks after the start of tamoxifen treatment

digestive/alimentary system
• frequent apoptotic figures in small intestine after tamoxifen treatment
• small intestinal atrophy

growth/size/body
• transiently lose about 20% of body weight within 1 week of tamoxifen injection

immune system
• expansion of myeloid cells spreads to peripheral tissues in mice that survive more than 2 weeks after tamoxifen treatment
• expansion of monocytes is accompanied by profound reduction in B lymphocytes and/or their progenitors
• accumulation of monocytes in the spleen and bone marrow

neoplasm
• expansion of myeloid cells is histopathologically reminiscent of histiocytic sarcoma

cellular
• frequent apoptotic figures in small intestine after tamoxifen treatment
• small intestinal atrophy
• frequent apoptotic figures in small intestine after tamoxifen treatment

hematopoietic system
• expansion of myeloid cells spreads to peripheral tissues in mice that survive more than 2 weeks after tamoxifen treatment
• expansion of monocytes is accompanied by profound reduction in B lymphocytes and/or their progenitors
• accumulation of monocytes in the spleen and bone marrow
