Regenerative capacity of normal and irradiated liver following partial hepatectomy in rats.

Purpose: To investigate the regenerative capacity and proliferation related to cell cycle modulators in irradiated livers after partial hepatectomy (PH) in rats.

Methods And Materials: Two experimental groups were given a single dose of either 4-Gy or 8-Gy photon radiation to the whole liver following PH. The control group underwent only PH, without irradiation.
