Ultrastructural changes induced by p-benzoquinone in the terminal abdominal ganglion of the cockroach.
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.
