RESUMO
Objective: To study the preventive actions of ganoderma lucidum polysaccharide(GLP) against kidney damage induced by cisplatin. Methods : Female Wistar rats were randomly divided into normal saline(NS) group, cisplatin(CDDP) group, GLP group, CDDP+GLP group. The changes of Scr, BUN, MDA, SOD were measured and renal structure was observed after 5 days by injecting drugs. Results : The contents of serum Scr and BUN of CDDP group were significantly highter than that of NS group. The activity of RBC SOD reduced and the contents of serum MDA increased. The contents of renocortical tissue MDA increased and the activity of SOD declined in renocortical tissue. The contents of serum Scr and BUN of GLP+CDDP group were significantly lower than that of CDDP group. The activity of RBC SOD increased and the contents of serum MDA declined. The concents of renocortical tissue MDA declined and the activity of SOD increased in renocortical tissue. The pathological slice indicated that renal structure was significantly improved. Conclusion : GLP may reduce cisplatin nephrotoxicity and its mechanism may be correlative with that GLP inhibited the blood and renocortical tissue lipid peroxidation increasing.
