Outline of Final Research Achievements |
Comparison of AGEs (MG and CML) in the posterior longitudinal ligament between three groups of rats (about 6 months old):1) Zucker Diabetic Fatty (ZDF) rats (fa/fa); model rats for type 2 diabetes, 2) Zucker Fatty rats (fa/fa); non-diabetic obese rats, and 3) their control, Zucker Fatty rats (+/+). In ELISA, there was no significant increase in either MG or CML in ZDF rats. Similarly, histological evaluation showed no significantly stronger staining of MG or CML in ZDF rats than in rats of other species.

Academic Significance and Societal Importance of the Research Achievements |
脊椎靭帯骨化症は、糖尿病や肥満を多く合併している傾向があるが、その機序の詳細は不明である。高血糖状態では糖とタンパクは架橋形成により終末糖化産物(Advanced Glycation End Products; AGEs)を形成し、タンパクを変性劣化させることが注目されている。本研究においては、糖尿病ラットおいて、脊椎靭帯にA G Esの有意な蓄積は認められなかった。この成果は、糖尿病やその他代謝疾患と靭帯骨化の研究発展の一助となると考える。
