Abstract
Intravenous administration of sodium benzylideneascorbate (SBA) dose-dependently induced degeneration (vacuolar and eosinophilic degeneration and cell shrinkage and nuclear condensation, which are characteristic of apoptotic cell death) of 3'-methyl-4-dimethylaminoazobenzene-induced rat hepatocellular carcinoma. SBA did not significantly induce lymphocyte infiltration and fibrosis in the liver, nor damage the gross morphology of kidney and spleen cells. SBA failed to stimulate the production of tumor necrosis factor and interleukin-1 beta in both in vitro and in vivo systems. These results may suggest a direct antitumor action of SBA via induction of apoptosis in the tumor. However, SBA did not significantly affect the doubling time, or the extent of invasion and differentiation of dimethylhydrazine-induced colon carcinoma in rats. These data suggest that the conditions of SBA administration should be re-established for each tumor sample to produce maximum antitumor activity.
