Abstract
We studied the effect of human lactoferrin on cells of the hippocampal dentate gyrus of 2-2.5-month-old male C57BL/6 mice after acute gamma irradiation of the head in a dose of 8 Gy from a 60Co source. Immediately after irradiation some animals received an intraperitoneal injection of human lactoferrin (4 mg/mouse). The appearance of TUNEL+ cells in the subgranular zone 6 h after irradiation was accompanied by a corresponding decrease in the number of Ki-67- and DCX-immunoreactive cells. Administration of lactoferrin had a protective effect on mouse brain cells, which manifested in a decrease in the number of TUNEL+ cells (by 77% relative to the irradiation alone) and an increase in the number of proliferating cells (from 16 to 61% relative to control animals) and immature neurons (from 14 to 22% relative to control animals) in the dentate gyrus of the hippocampus.
