Changes on the serum IL-6 and IFN-γ levels in H520 tumor cell xenograft mice. Values are expressed Mean ± SD of eight mice (pg/ml); TB = tumor-bearing; IL = interleukin; IFN = interferon Gemcitabine was intraperitoneally administered at 160 mg/kg, 7-day intervals; Platycodin D was orally administered, once a day; and as compared with intact control by MW test; and as compared with TB control by MW test.
