| Abstract: | After I. V ~(85)Sr, the whole body ~(85)Sr-retentions in rats were fit totwo compartment exponential equations. The equation parameters showed a sigificantlydifference between the young group and both the adult and old groups (p<0 .01). butthere is no significant difference seen between the latter two groups. The biologicalhalf life(Tb_2) for ~(85)Sr in the slow compartment decreased in regular order from theyoung to the old groups. 1n the bone ~(85)Sr-retention equations Tb_2 of the slow compa-rtment for ~(85)Sr in the young group was sigificantly lower than the adult and oldgroups. The doses of the whole body and red-marrow for young rats were 4.2 timesas much as those of adult rats, and 6.2 and 5.9 times as much as those old rats. Thedose-cumulative speeds was most quick in the young groups and similar in the adultand the old. |
