The study of the distribution of Ca{sup 45} with time in the newborn rat by the autoradiography method at - 195 deg; Etude de la distribution du {sup 45}Ca en fonction du temps chez le rat nouveau-ne par la methode d'autoradiographie a -195 deg

Abstract

Ca{sup 45} metabolism has been studied as a function of time by autoradiography at -195 deg. C in the new-born rat after sub-epidermal dorsal injected of 20 micro-curies per animal. This study confirms: 1) The existence of a rapidly exchangeable calcium bone fraction; 2) A considerable intestinal excretion of radio-calcium, much greater than the urinary elimination; 3) A gradual transfer of the activity for the long bones of the epiphyseal to the diaphyseal regions during growth, together with secondary modifications during ossification.

C, chez le rat nouveau-ne apres injection sous-epidermique dorsale de 20 microcuries par animal. Cette etude confirme: 1) l'existence d'une fraction calcique osseuse rapidement echangeable; 2) une excretion intestinale considerable du radiocalcium, tres superieure a l'elimination urinaire; 3) un transfert progressif de l'activite pour les os longs des regions epiphysaires aux regions diaphysaires au cours de la croissance, ainsi que les remaniements secondaires au cours de l'ossification.
