Autoradiographic measurement of relative changes in ornithine decarboxylase in axotomized superior cervical ganglion neurons.
An autoradiographic method is described for detecting changes in ornithine decarboxylase in axotomized superior cervical ganglion neurons of rats using [3H]difluoromethylornithine. An increase in binding to neurons was seen at 12 h and 1 day after crushing the postganglionic nerves. Binding returned to control values between 3 and 5 days postoperation. The patterns found using this method were in general agreement with prior reports of enzymatic changes in whole ganglia.
