title: Effect of the polychlorinated biphenyl preparation, Aroclor 1242, on the quantity of neurosecretory material in the medulla terminalis X-organ of the fiddler crab, Uca pugilator.
abstract: Exposure of the fiddler crab, Uca pugilator, to the PCB preparation, Aroclor 1242, produces an increase in the quantity of neurosecretory material in the medulla terminalis X-organ. This Aroclor apparently inhibits release, but not synthesis, of one or more neurohormones.
