in intact rats hepatic glycogen content 2 h after hormone injection was higher in proinsulin than in insulin treated animals despite similar preceding hypoglycaemia which might suggest a preferential inhibitory action of proinsulin on hepatic glycogen breakdown ( 135 mumol glycosyl units/g liver for proinsulin-injected and 82 mumol glycosyl units/g liver for insulin-injected rats at half-maximal hypoglycaemia ) .
