Abstract:
We observed the effects of naringin on bone loss in glucocorticoid-treated inflammatory bowel disease (IBD) in a rat model. The IBD model was established in Sprague-Dawley rats by administering 5.0% dextran sodium sulfate. Dexamethasone (DEX) and naringin were given at the second week. Blood, colon and bone samples were collected for biomarker assay, histological analysis or microCT analysis. Superoxide dismutase, catalase and malonaldehyde were measured in bone. A significant decrease of procollagen type 1 N-terminal propeptide (P1NP) level was observed in DEX-treated IBD groups compared with the control (p < 0.05). P1NP levels were dose-dependently increased in the presence of naringin intervention. Bone loss and decreased bone biomechanical properties were observed in DEX-treated IBD rats compared with control rats (p < 0.01). Naringin intervention protected against bone loss and decreased bone biomechanical properties. Bone formation related gene mRNA expressions were significantly decreased in DEX-treated IBD rats compared with control rats. Naringin administration reversed the down-regulation of the expressions of those genes. Naringin treatment reduced the oxidative stress in bone from DEX-treated IBD rats. Our data indicated that naringin may have great potential for the treatment of bone loss in glucocorticoid-treated IBD patients via blocking oxidative stress and promoting bone formation.

01:30Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
01:27Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
