the present paper investigated the effect of restricted feeding ( 11.00 to 13.00 h ) by a single daily meal upon the activity of various oxidoreductases of the rat gastric mucosa ( sdh , alpha-gpdh , ldh , nadhtr ) , which at ad libitum feeding under normal lighting conditions with a dark night were shown to have distinct circadian activity variations related to the rat 's nocturnal food intake preference ( zaviacic and brozman 1978a ) .
