ABSTRACT
Aim To study the protective effects of Ganoderma lucidum polysaccharides peptide(GLPP)on ECV304 from oxidative injury.Methods Cultured ECV304 were injured by oxygen free radicals derived from tBOOH.Various concentrations of GLPP(12.5,25,50,100 mg?L-1)were added into culture medium.The survival rate of cells was measured by MTT assay.The morphological change of cells and injury of mitochondria were examined under the light and electron microscopes.The percentage of apoptosis of ECV304,labeled with AnnexinV/PI,was measured by flow cytometry.Results GLPP(12.5,25,50,100 mg?L-1)could reduce oxidative injury induced by tBOOH in ECV304 cells.The survival rate of cells treated with GLPP increased.The light microscopic examination showed that the injured cells decreased in GLPP-treated groups.Under the electron microscope it was found that GLPP(50 mg?L-1,incubated for 24 h)could protect the organelle such as mitochondria from oxidative injury and cells from apoptosis by tBOOH.The result of flow cytometry showed that the total percentage of apoptosis in control,GLPP and injury treated group was 2.24%?0.43%,24?6.4%(P
