We show that calmodulin-dependent phosphodiesterase (CAM-PDE) is selectively expressed in mature olfactory receptor neurons within the olfactory mucosa. Immunocytochemical staining reveals neuronal immunoreactivity that is most pronounced within cilia, dendritic knobs, and axon bundles. Neither sustentacular cells nor basal cells display immunoreactivity. The extent of loss of neuronal immunore...

The response of olfactory sensory neurons to TNT and RDX as well as to some volatile organic compounds present in the vapors of antipersonnel landmines has been studied both in the pig and in the rat. GC/MS analyses of different plastic components of six different kinds of landmines were performed in order to identify the components of the "perfume" of mines. Studies on rat olfactory mucosa wer...

In both humans and animals, chemosensory stimuli, including odors and tastes, induce a variety of physiologic and mental responses related to energy homeostasis, such as glucose kinetics. The present study examined the importance of olfactory function in glucose kinetics following ingestion behavior in a simplified experimental scenario. We applied a conventional glucose tolerance test to rats ...

BACKGROUND OMT tends to involve treatment over an extended period of time. Some OMT patients terminate the treatment. There is a need for more knowledge about how these persons do following treatment. MATERIAL AND METHOD We undertook a retrospective review of patient records at Sørlandet Hospital in Kristiansand for patients who had undergone OMT in the period 1998-2009. Data from 103 dischar...

The olfactory acuity of 29 patients receiving laryngectomy was prospectively studied. The olfactory acuity was evaluated by Jet Stream Olfactometer (JSO) and Alinamin test preoperatively and at 3, 6 and 12 months postoperatively. The findings of nasal/olfactory mucosae were also observed by rigid endoscope. Based on the results of JSO, the averages of detection/recognition thresholds tended to ...

There are myriads of odorous molecules that we perceive and it is remarkable that most of us seem to have very similar odor impressions that originate from a specific stimulus and the sense of smell appears to be robust during much of a lifetime. When perceiving scents, olfactory receptor (OR) proteins are at work to translate chemical information into neuronal signals that are decoded in the o...
