Characteristics

Low mammary tumours, some lung tumours in older mice (Staats, 1976). Ovaries often appear pale and enlarged and have an infiltration of amyloid. Thought to be due to necrotising arteritis in which there is a thickening of the walls of the vessels to duodenum and ovaries due to a deposition of eosinophilic material within the intima and media (Deringer, 1959b). Aseptic necrosis of bone in 22% of females often resulting in fracture of femoral neck and other complications, so that the animals are severely crippled (Sokoloff and Haberman, 1958).
