Radiation-induced aging on five serum components which were total cholesterol, inorganic phosphorus, albumin, glucose and GOT and considered to depend on age were measured sequentially in SAM-P/1 which was the senescence accelerated mouse.The regression equations of each observed value on age of week were calculated by each groups whose radiation dose were 0, 2, 3 and 4 Gy. The equality and dose-dependency of each regression coefficients were tested between groups.In inorganic phosphorus, radiation-induced aging was observed, and the type of aging was the accelerated aging, which changed the slant in regression line.In total cholesterol, albumin, glucose and GOT, radiation-induced aging were not observed.From these results, it was considered that the radiation-induced aging was different by items.
