In vivo inhibition of KB xenograft proliferation by AP extracts. (a) Nude mice were untreated (control) or treated with 10 mg/kg of AP extracts. On the 27th day after tumor implantation, the animals were sacrificed and the tumors were removed. (b) The control KB xenograft tumor and the KB xenograft tumors after AP extract treatment were sectioned and stained with hematoxylin and eosin, examined with light microscopy. Arrows indicate mitosis-positive cells. Typical results from three independent experiments are shown.
