Evoked response to olfactory stimulations in anosmic patients.
نویسنده
چکیده
In our study, we explored the influence of blast method introduction of odorant on evoked response. In normal patients, no detectable response was observed in the absence of an odor, and introduction of an odorant at the end of inspiration or during expiration did not result in any detectable positive response. In anosmic patients, glacial acetic acid, which is thought to be a strong trigeminal stimulating agent, evoked a negative response without detection of odor. Accordingly, the positively evoked response to odorant was thought to be elicited mainly by the odorant, not by the trigeminal stimulations or the auditory stimulations (or both).

متن کاملPrevalence of Olfactory and Other Developmental Anomalies in Patients with Central Hypogonadotropic Hypogonadism
INTRODUCTION Hypogonadotropic hypogonadism (HH) is a heterogeneous disease caused by mutations in several genes. Based on the presence of hyposmia/anosmia it is distinguished into Kallmann syndrome (KS) and isolated HH. The prevalence of other developmental anomalies is not well established. METHODS We studied 36 patients with HH (31 males, 5 females, mean age 41.5), 9 with familial and 27 wi...

متن کاملBrain single photon emission computed tomography in anosmic subjects after closed head trauma.
Anosmia following head trauma is relatively common and in many cases is persistent and irreversible. The ability to objectively measure such a decline in smelling, for both clinical and medicolegal goals, is very important. The aim of this study was to find results of brain Single Photon Emission Computed Tomography (SPECT) in anosmic subjects after closed head trauma. This case-control cross s...
متن کاملANOSMIA IN ZnSO4-TREATED PIGEONS: LOSS OF OLFACTORY INFORMATION DURING ONTOGENY AND THE ROLE OF SITE FAMILIARITY IN HOMING EXPERIMENTS
Depriving homing pigeons of olfactory information by spraying an 18% zinc sulphate solution onto their olfactory ephithelium results in anosmia that persists for at least 5 days (tested using the ‘orienting response’). To study whether anosmic zinc-sulphate-treated pigeons (ZnSO4-pigeons) were able to compensate for their loss of olfactory information by using familiar landmarks, we made releas...
