title: Ultrastructural changes induced by p-benzoquinone in the terminal abdominal ganglion of the cockroach.
abstract: The morphology of the sixty abdominal ganglion, associated connectives and cercal nerves was examined using an electron microscope after acute treatment of the isolated tissue with 0.5 mM p-benzoquinone. A high incidence of mitochondrial damage was observed in all three regions of the tissue. This may be due to a metabolic inhibitory action or a pro-oxidant action of p-benzoquinone.
