The present study was undertaken to examine the effect of rare sugar D-psicose on the protection of pancreatic b-islets using Otsuka Long-Evans Tokushima Fatty (OLETF) rats, a T2DM model. Treated rats were fed with 5% D-psicose or 5% D-glucose supplemented drinking water, and only water in the control for 13 weeks. A non-diabetic Long-Evans Tokushima Otsuka (LETO), fed with water served asa counter control of OLETF. D-Psicose signiﬁcantly attenuated progressive b-islet ﬁbrosis and preserved islets, evaluated by hematoxylin–eosin staining, Masson’s trichrome staining and immunostainings of insulin and a-smooth muscle actin (SMA). D-Psicose signiﬁcantly reduced increase in body weight and abdominal fat deposition. Oral glucose tolerance test (OGTT) showed reduced blood glucose levels suggesting the improvement of insulin resistance. All these data suggests that D-psicose protected and preserved pancreatic b-islets through the maintenance of hyperglycemia and by the prevention of fat accumulation in OLETF rats.\u003Cbr>􀀂 2012 Elsevier Inc.

Introduction  \nPrevalence of global obesity has been increasing with alarming health problems day by day. Obesity is characterized by excess accumulation of fat and is associated with multiple complications, including T2DM [1] which also becomes a health problem and is thought to typically develop after age 40, but it is now increasingly seen in younger ages as obesity increases and physical activity decreases.  \nIn T2DM the body either does not produce enough insulin or there is insulin resistance resulting in the failure of sugar movement into the cells [2]. Initially, pancreatic b-islets produce more insulin to overcome the hyperglycaemic state resulting in islet hypertrophy that gradually proceeds to b-cell failure [3] and progressive failure leads to glucose intolerance followed by T2DM. Studies with rodents showed that decrease in b-cell mass play important roles in the pathogenesis of human T2DM [2]. If remains untreated, the consequences of T2DM can be life-threatening. Although there is no cure for T2DM, but it is manageable or even  \n⇑ Corresponding author. Fax: +81 87 891 2096.  \nE-mail address: [tokuda@med.kagawa-u.ac.jp](tokuda@med.kagawa-u.ac.jp) (M.

Therefore, it is important to seek effective therapeutic interventions for the prevention and treatment of diabetes and its complications. Under these circumstances, the use of alternative medicines has increasingly become the focus of attention. And thus we introduce D-psicose, a non-toxic zero-calorie rare sweet monosaccharide as an effective agent against
