Objective To investigate the therapeutic effect of injectable doxorubicin-containing hydrogel on glioma.Methods The release of doxorubicin hydrogel in vitro was detected by dialysis.The subcutaneous C6 glioma model of rats was constructed and divided into blank control group,intravenous injection group and hydrogel group according to different administration methods.The distribution of doxorubicin in the tumor was detected by immunofluorescence 15 hours after administration.After 7 days of administration,the tumor inhibition rate of each group was calculated.The tumor tissue was stained with hematoxylin eosin.Results In vitro,doxorubicin-containing hydrogels had sustained drug release properties.In vivo,compared with intravenous administration,local injection of doxorubicin-containing hydrogel resulted in more doxorubicin distribution,higher tumor inhibition rate(42% vs 64%)and more obvious tumor cell necrosis.Conclusions Doxorubicin-containing hydrogel can provide a new carrier
for local chemotherapy of glioma.
