Changes on the splenic and peritoneal NK cell activities in H520 tumor cell xenograft mice. Values are expressed Mean ± SD of eight mice (% specific ⁵¹Cr releases); TB = tumor-bearing; NK = natural killer; Gemcitabine was intraperitoneally administered at 160 mg/kg, 7-day intervals; Platycodin D was orally administered, once a day; as compared with intact control by LSD test; as compared with TB control by LSD test; and as compared with intact control by MW test; and as compared with TB control by MW test.
