title: [Effect of fixation in Carnoy's solution on nucleic acid and protein concentration in the rabbit superior cervical sympathetic ganglion].
abstract: By means of biochemical techniques, the stability of RNA, DNA and protein contents has been demonstrated in the rabbit superior cervical sympathetic node fixed in Carnoy's solution for 2 hours at 4 degrees C. A 2 hour fixation in Carnoy's fluid at room temperature, results, however, in a considerable loss of RNA (21%). The loss of DNA and protein did not exceed 2% of the total amount of the fresh ganglion tissue. Fixation at a higher temperature (37%) increased the loss percentage protein and of nucleic acids: 3.1, 5.5 and 42%, for protein, DNA and RNA, resp.
