Abstract

Aldolase, lactate dehydrogenase, and succinate dehydrogenase activities were measured in body wall muscle of Lampito mauritii and Perionyx excavatus acclimated to 17° and 10°, resp. Aldolase activity significantly increased and succinate dehydrogenase activity decreased in earthworm muscle during cold acclimation. The relative activities of 4 lactate dehydrogenase isoenzymes significantly changed in cold acclimation. Similar results were found in worms kept at control temps. after a coelomic injection of nerve cord exts. from cold-​acclimated worms. Apparently, neurohumoral factors which regulate metabolic pathways are synthesized by earthworms during cold acclimation.
