Effect of antibodies against S-100B antigen in ultralow doses on sucrose consumption during learning

We studied the effect of potentiated antibodies against S-100B antigen on 20% sucrose consumption by Wistar rats under conditions of free-choice drinking from the bowls with sucrose and water during presentation of an acoustic pre-nociceptive or neutral signal. Peroral administration of antibodies after training sessions increased the number and duration of contacts with sucrose solution.
