A bioactive extract from parched and ground garden slugs has H1-antihistamine properties which inhibited contraction of guinea pig in vitro tracheal muscle preparation and cutaneous allergic responses.

We found that the two-week choline supplementation in young rats improved the consolidation of short-term memory into intermediate long-term memory.
