| Abstract: | The activity of natural killers from the mouse spleen was determined by 51Cr clearance from labeled target cells (YAC-1) at different times after resection of the two-thirds of the spleen. In the early periods after operation, there was a decrease in the natural cytotoxic activity of splenocytes followed by a relatively rapid rise for 8 days until the maximum exceeding the cytotoxicity of intact spleen cells was reached. However, the total lytic potential of the regenerating spleen did not return to normal during 28 days. |
