چکیده
酒粕は清酒を醸造する際に圧搾した後の副産物であり, その多くは産業廃棄物として処理されている。しかし, 酒粕には米由来の成分だけではなく酵母や麹菌の菌体成分, その代謝産物も含むため栄養価が高く, 様々な生理機能が報告されている。本研究では, 凍結乾燥させた酒粕を混合した飼料を2型糖尿病モデルマウスに摂取させることで得られる効果について検証した。糖尿病モデルマウスに酒粕混合食を40日間摂食させた結果, 随時血糖値の上昇が有意に抑制され, 経口糖負荷試験 (OGTT) においても改善傾向が確認された。血清インスリン濃度は酒粕を与えることで減少し, 血清アディポネクチン濃度は有意に増加した。さらに, 酒粕混合食群では骨格筋でのglucose transporter 4 mRNAの発現が有意に増加した。これらの結果から, 凍結乾燥させた酒粕には2型糖尿病における耐糖能異常の発症を抑制する効果があることが示唆された。

Changes in plasma nitric oxide metabolites concentration during glucose tolerance test in type 2 diabetic rats
Introduction: Repeated hyperglycemia play an important role in the development of atherosclerosis in diabetic patients. Endothelium is the organ of the first-line defense against atherosclerosis and nitric oxide has a major role in this task. The aim of this study was to determine changes in plasma nitric oxide metabolites concentration during glucose tolerance test in type 2 diabetic rats. Me...
متن کاملEffect of the Direct Renin Inhibitor Aliskiren on Urinary Albumin Excretion in Spontaneous Type 2 Diabetic KK-Ay Mouse
Objective. Although angiotensin II-mediated inflammation and extracellular matrix accumulation are considered to be associated with the progression of diabetic nephropathy, these processes have not yet been sufficiently clarified. The objective of this study was to determine whether the correction of the abnormal renal expression of MMPs and its inhibitors (MMPs/TIMPs) and cytokines following t...
متن کاملLessons From the KK-Ay Mouse, a Spontaneous Animal Model for the Treatment of Human Type 2 Diabetic Nephropathy
Diabetic nephropathy is a major cause of end-stage kidney disease (ESKD) in patients with type 1 and type 2 diabetes throughout the world. In human glomeruli, expansion of diffuse mesangial matrices, exudative lesions and/or segmental nodular sclerosis are pathological features of diabetic nephropathy. There have been many reports on the pathogenesis and treatment of type 2 diabetes using vario...
متن کاملCharacteristics of diabetic osteopenia in KK-Ay diabetic mice.
We examined the bone mineral density (BMD) of the proximal region and the mid-diaphysis of the femur using dual energy X-ray absorption (DXA), the blood osteocalcin level and the blood glucose level every five weeks from 8 to 23 weeks old in KK-Ay diabetic mice. The BMD of the proximal region after 18 weeks old was significantly lower when compared with that at 8 weeks old (p<0.05), whereas the...
