title: [The effect of repeated amputations on planarian regeneration in the presence of the heat-stable toxin from Bacillus thuringiensis].
abstract: The exotoxin of Bacillus thuringiensis, which is an inhibitor of RNA synthesis, inhibits Planarian regeneration. Planarians which have been cut twice at the same level are able to regenerate after the second section in the presence of the toxin. This indicates that the first amputation stimulates a synthesis of stable RNAs which thus are available for regeneration at the moment of the second section.
