title: Effects of anesthesia on the electrolyte concentrations in blood and coelomic fluid of the earthworm, Pheretima communissima.
abstract: Sodium, potassium, calcium and magnesium concentrations in blood and coelomic fluid of Pheretima communissima under various methods of anesthesia or in the unanesthetized condition were determined. All electrolyte concentrations determined in ethanol-anesthetized earthworms were not significantly different from those in unanesthetized earthworms. Thermal (warming, cooling) anesthesia, urethane and chloretone brought about increases or decreases in some electrolyte concentrations in the blood or coelomic fluid. However, not all electrolytes responded similarly to a method of anesthesia.
