Adjuvant chemoprevention of experimental cancer: catechin and dietary turmeric in forestomach and oral cancer models.

Catechin and dietary turmeric (Curcuma longa) were used as chemopreventive agents in benzo[a]pyrene induced forestomach tumors in Swiss mice and methyl-(acetoxymethyl)-nitrosamine induced oral mucosal tumors in Syrian golden hamsters. Catechin in drinking water and dietary turmeric significantly inhibited the tumor burden and tumor incidence in both tumor models. The induction of oral tumors in golden hamsters was delayed by catechin and dietary turmeric.

Some behavioural effects of quinine in mice.

The effects of quinine on motor activity, pentobarbitone-induced sleep and gross behaviour were examined in mice. Low doses of quinine (0.1-0.
