Abstract:
OBJECTIVE:To study the effects of nimesulide combined with oxaliplatin on transplanted tumor growth and im-mune function of rats with esophageal cancer. METHODS:Rats were randomly divided into model group(intragastrically given So-dium carboxymethyl cellulose solution+intravenously given 5% Glucose injection in tail),nimesulide group(intragastrically given 20 mg/kg),oxaliplatin group(intravenously given 13.6 mg/kg in tail)and combination group,10 in each group. Esophageal can-cer Eca109 cells were subcutaneously injected to develop transplanted tumor model. After modeling,rats in each group received rel-evant medicines by corresponding ways,once a day for ig,once every 4 d for iv in tail. Rats were sacrificed after 8 weeks,tumor volume and quality of rats were measured,tumor inhibition rate was calculated,and contents of tumor markers(CEA,CYFRA21-1,SCCAg),percentages of immune cells(CD3+,CD4+,CD8+T cells and NK cell)in peripheral blood were detected. RESULTS:Compared with model group,tumor volume and quality in other 3 groups were decreased (P<0.05);contents of tumor markers were decreased (P<0.05). Percentages of CD3+,CD4+ T cells and NK cell in nimesulide group were increased,percentages of CD8+T cell was decreased(P<0.05). Percentages of CD3+,CD4+T cells and NK cell in oxaliplatin group and combination group were decreased,percentages of CD8+ T cell was increased(P<0.05). Compared with nimesulide group and oxaliplatin group,tu-mor inhibition rate in combination group was increased(P<0.05);contents of tumor markers were decreased(P<0.05);percent-ages of immune cells were lower than nimesulide group and higher than oxaliplatin group(P<0.05). CONCLUSIONS:Nimesulide can enhance the oxaliplatin's antitumor effect on esophageal cancer,and decrease its inhibition degree on immune functions.
