| Research Abstract |
Recently, it was suggested that a possibility about acetaldehyde inhibits advanced glycation end products (AGE) formation, it effects toxically in vivo, at the stage of amadori products (AP). On the other hands, there was many reports that modelate drinking is good for human health. In this study, we examined about the function of acetaldehyde-amadori products (AAP) formed by acetaldahyde and AP.
At first, we made rabbit albumin -AAP (RA-AAP), and it immunized rabbit (nihon shiro) every two weeks. After 8 weeks, their serum were examined by ELISA, but we could not find the increase specific antibodies. The reason of this result, it was thought a possibility that AAP exists from the beginning in vivo.
Furthermore, we researched the neurotoxicity of AAP and AGEs in primary cultured cortical neuronal cells of the fetal rat. The results showed AGE had strong neurotoxicity, but not AAP.
We could not achieve making the antibody for AAP, but in this study, the results followed our hypothesis that acetaldehyde have neuroprotective function in vivo. Further investigation, we have to clarify about metabolism and reactive roots of acetaldehyde.
