Plasma alkaline phosphatase in mice with experimentally-induced osteosarcomas

No statistically significant difference in alkaline phosphatase levels was demonstrated in animals injected with the FBJ virus. However, there was a significant increase associated with the development of osteosarcomas in response to the iv injection of 1.0 uCi 90 Sr/g body weight into 11-18-mo-old Anl:CFl females. It was proposed that alkaline phosphatase determinations can be used as well as roentenographic analysis to detect 90Sr-induced tumors in mice.
