Seirogan, a wood creosote, has been used as an antidiarrhetic drug in Asian countries including Japan for many years. This antidiarrhetic has recently been used as a sugar-coated pill because Seirogan has a strong smell. The strong smell of the uncoated form of Seirogan may modulate the defense systems of animals because the sense of smell is important for the detection of toxic metabolites in ...

OBJECTIVE To compare olfactory function in vascular parkinsonism and Parkinson's disease diagnosed according to published clinical diagnostic criteria. METHODS The University of Pennsylvania smell identification test (UPSIT) was carried out in 14 patients with vascular parkinsonism, 18 with Parkinson's disease, and 27 normal controls matched for age, sex, and smoking status. RESULTS UPSIT s...

solid rectangles were yellow and in the debris were found yellow cylinders much smaller than the rectangles. The smell was suggestivje of bile salts. The fortifying effect of the sample on Jhe alcoholic heart extract, in the Wassermann reaction, was appreciably reduced. For the removal of the colour and smell the sample was submitted to four processes : (i) one gramme was subjected to negative ...

Perception Perception (from the Latin perceptio, percipio) is the organization, identification, and interpretation of sensory information in order to represent and understand the environment. All perception involves signals in the nervous system, which in turn result from physical or chemical stimulation of the sense organs. For example, vision involves light striking the retina of the eye, sme...

Uvulopalatopharyngoplasty (UPPP) has been a popular surgical method for treating obstructive sleep apnea syndrome since it was introduced in the early 1980s. Olfactory loss has been reported as a rare side effect in several cases. However, the olfactory test results and the prognosis were not mentioned in these cases. We present two patients who complained of loss of olfactory function after UP...

BACKGROUND Deficits of flavour processing may be clinically important in frontotemporal lobar degeneration (FTLD). OBJECTIVE To examine flavour processing in FTLD. METHODS We studied flavour identification prospectively in 25 patients with FTLD (12 with behavioural variant frontotemporal dementia (bvFTD), eight with semantic variant primary progressive aphasia (svPPA), five with non-fluent ...

Scores on the University of Pennsylvania Smell Identification Test (UPSIT), as well as the numbers of MRI-determined plaques within the inferior frontal and temporal lobes, were obtained on three or four separate occasions in each of five MS patients over an 18- to 20-month period. A close association was observed, longitudinally, between the remission and exacerbation of plaque numbers and UPS...

Humans use a repertoire of > 400 olfactory receptors (ORs) to perceive odorants. The sense smell is complex trait whereby genetics and environmental factors interplay. To date, still little known regarding the smell, even though high genetic variability ORs genes has already been demonstrated. Recently significant association between cinnamon odorant recognition rs317787 polymorphism, located i...
