| Research Abstract |
There are some reports that the divergence of susceptibility of alcohol may affect the glycemic control among the people with heavy or continuous alcohol intake. The research related to the divergence of susceptibility may be more important in Japan, because approximately 40% of Japanese have inactive aldehyde dehydrogenase (ALDH) 2 and the patients with type 2 diabetes are increasing in number. Moreover, the effect of abnormality of glucose tolerance in terms of ALDH genotype among normal subjects has not been investigated previously. The present study revealed that drinking alcohol together with a simple sugar causes enhancement of early insulin response, which is more prominent in people with normal ALDH 2 phenotype than in those with atypical ALDH 2 phenotype. On the other hand, p-hydroxyacetophenonc (p-HAP)-sepharose is known to he an effective ligand for isolation of ALDH from the liver. In the present study, we demonstrated the ability of this ligand to bind glycogen phosphorylase (GP), adenosine kinase, class I ADH and glutathione S-transferase as well as cytosolic ALDH in the liver. This result may suggest that the possibility of relationship between alcohol metabolism (ADH and ALDH) and glucose (GP) metabolism. Furthermore, vasorelaxant effect of p-HAP on isolated rat aorta was also elucidated.
