Method for estimating the change of body smell with ageing |
摘要 |
It is desirable to provide a gas chromatography type of chemical analysis method for estimating the change of body smell with progressive ageing of a living subject over a period of years by 1) utilization of the smell distinguishing ability of an experimental animal, 2) instrumental analysis, or 3) a combination of them.The present inventors found that the amounts of several volatile organic substances (e.g., 2-phenylacetamide, indole and phenol) present in mouse urine as substances responsible for the body smell are increased or decreased with ageing. The change in body smell with ageing of an animal can be estimated by quantitatively analyzing these compounds by an instrumental analysis method such as Y-shaped labyrinth method (involving live animals in a maze), gas chromatograph (GC) or high performance liquid chromatography (HPLC).
