Abstract
The local antitumor activities and inflammation-inducing activities of various antitumor polysaccharides were examined, and the relation between the 2 types of activity was studied. The tested antitumor polysaccharides included MG (a mannoglucan prepared from the culture fluid of Microellobosporia grisea), lentinan, bacterial [Escherichia coli] lipopolysaccharide, TAK (a glucan from Alcaligenes faecalis) and their derivatives. Local antitumor activity was tested by intratumoral administration of the polysaccharides 4,7 and 10 days after inoculation of MH134 [mouse] hepatoma intradermally into the abdomen of C3H/He mice. MG and its derivatives showed strong local antitumor activity. Inflammation-inducing activity was assayed by measuring footpad swelling and accumulation of i.v.-injected 51Cr-labeled spleen cells after injection of the test materials into the footpads of C3H/He mice. TAK had the strongest inflammation-inducing activity among the polysaccharides tested. No close correlation was found between the local antitumor activity and the inflammation-inducing activity.
