Expression of the CCK-A receptor gene in the pancreas and pancreatic exocrine function was examined in diabetic model rats (OLETF) at 5 wks of age. Little or no CCK-A receptor was detected in the pancreas of OLETF rats. Pancreatic exocrine function in response to exogenous CCK and to bile-pancreatic juice diversion (endogenous CCK) was impaired in conscious OLETF rats. The pancreatic insulin and protein contents of OLETF (Otsuka Long-Evans Tokushima Fatty) and control LETO (Long-Evans Tokushima Otsuka) rats were not significantly different. No histological abnormalities or expression of pancreatitis associated protein (PAP) mRNA was detected in the pancreas in either group. These results suggest that OLETF rats are a new experimental model for congenital deficiency of CCK-A receptor in the pancreas.

Background And Purpose: Eukaryotic elongation factor 2 kinase (eEF2K) belongs to the Ca/calmodulin-dependent protein kinase family. We previously revealed that A484954, a selective eEF2K inhibitor, caused hypotensive and diuretic effects via the production of nitric oxide (NO) in spontaneously hypertensive rats. Otsuka Long-Evans Tokushima Fatty (OLETF) rats are hypertensive because of obesity and type 2 diabetes.

, known as Aonori in Japan, is an edible alga species that is mass-cultivated in Japan. Supplementation with Aonori-derived biomaterials has been reported to enhance metabolic health in previous studies. This was an experimental study that evaluated the metabolic health effects of NBF2, a formula made of algal and -derived biomaterials, on obesity and type 2 diabetes (T2DM).

Obesity is a major global health concern. Studies suggest that the gut microflora may play a role in protecting against obesity. Probiotics, including lactic acid bacteria and , have garnered attention for their potential in obesity prevention.

Diabetes induces a range of macrovascular and microvascular changes, which lead to significant clinical complications. Although many studies have tried to solve the diabetic problem using drugs, it remains unclear. In this study, we investigated whether resistance exercise affects cardiovascular factors and inflammatory markers in diabetes.

Purpose: Bladder dysfunction associated with type 2 diabetes mellitus (T2DM) includes urine storage and voiding disorders. We examined pathological conditions of the bladder wall in a rat T2DM model and evaluated the effects of the phosphodiesterase-5 (PDE-5) inhibitor tadalafil.
Materials And Methods: Male Otsuka Long-Evans Tokushima Fatty (OLETF) rats and Long-Evans Tokushima Otsuka (LETO) rats were used as the T2DM and control groups, respectively.
