Abstract:
Objective To discuss the protective effects ofGuiqi YiyuanOintment on damages caused by heavy ion radiation induced bystander effects; To explore the possible mechanism.Methods Totally 42 Wistar male rats were randomly divided into blank control group, pure radiation group andGuiqi Yiyuan Ointment group. TheGuiqi Yiyuan Ointment group was givenGuiqi Yiyuan Ointment by gavage for two weeks in advance. Later the right lungs of the rats in the pure radiation group andGuiqi Yiyuan Ointment group were radiated once by 2 Gy12C6+, while the blank control group received no radiation. 6, 12, 24 h after radiation all groups of rats were executed. Peripheral hemogram and the levels of IL-6, TGF-β1 and IL-1β in serum of the rats were examined. The changes of lung tissue pathology morphology in the rats were observed by HE staining.Results Compared with the blank control group, the contents of IL-6, TGF-β1 and IL-1β in serum of the pure radiation group increased obviously at 12 h after radiation (P<0.01), and the amount of leukocyte, erythrocyte, blood platelet and hemoglobin distinctly declined at 12 h after radiation (P<0.01); HE staining showed that the alveolar wall was thickened at 24 h after radiation, and there were exudate and inflammatory cell infiltration in the alveolar cavity. Compare with the pure radiation group at 12 h after radiation, the levels of IL-6, TGF-β1 and IL-1β inGuiqi Yiyuan Ointment group decreased significantly at 12 h after radiation (P<0.01). Indexes of blood routine significantly increased (P<0.01), and the pathological changes of lung tissue in rats improved (P<0.01). ConclusionGuiqi Yiyuan Ointment can protect damages caused by heavy ion radiation induced bystander effects.
