| Abstract: | Summary A modification of Hansson's histochemical technique was used to reveal carbonic anhydrase activity in mounted cryostat sections of rat olfactory mucosa, after glutaraldehyde fixation. A positive reaction that could be inhibited by acetazolamide was found in a population of olfactory receptor cells, whereas the supporting cells were negative. Axons of receptor cells were also positive and could be traced through the cribriform plate to the olfactory bulb. |
