DIRECT ACTION OF X RAYS ON THE SPLEEN OF THE CHICKEN EMBRYO DURING MYELOGENESIS (in French)

Journal Article · · Compt. rend.
OSTI ID:4043203

The effect of x rays on the spleen during its myelogenesis was studied in chicken embryos exposed to 200, 400, 600, and 800 r on the 11th day of incubation. The results showed that the hemopoiesis is strongly affected even by 200 r. The cell progenitors show lesions with 400 r. The lymphocytic line is the most sensitive, decreasing in percentage from 200 r. The erythrocytic line is injured only by a dose of 600 r. However, even the lesions produced by a dose of 800 r do not appear definitive. Hemopoiesis recovers toward the 16th day of incubation for the lymphocytic and granulocytic lines, but the erythrocytic line is still deficient. (J.S.R.)
