    Journal: J Pediatr Surg; 2004 Feb; 39(2):139-43; discussion 139-43. PubMed ID: 14966727.
    Abstract:
    BACKGROUND/PURPOSE: Transfection of the HLA-B27 gene into normal Fischer rats induces phenotypic changes similar to inflammatory bowel disease (IBD). This study investigated the benefits of 2 doses of hepatocyte growth factor (HGF) on the manifestations of IBD in this rat model. METHODS: Fischer rats and HLA-B27 rats were divided into 4 groups: Fischer rats treated with saline, HLA-B27 rats treated with saline, HGF at 150 microg/kg/d, and HGF at 300 microg/kg/d. HGF or saline was infused for 14 days via an osmotic pump attached to a catheter in the internal jugular vein. After treatment, rats were evaluated for diarrhea and reduction in gross and microscopic bowel inflammation. Statistics were determined using analysis of variance (ANOVA). A P value < or =.05 was considered significant. RESULTS: Administration of HGF at 150 microg/kg/d decreased diarrhea by 40%, gross inflammation by 41%, and microscopic inflammation by 72% (P < or =.05). At 300 microg/kg/d HGF decreased diarrhea by 46%, gross inflammation by 45%, and microscopic inflammation by 54% (P < or =.05). CONCLUSIONS: HGF administration reduces the clinical manifestations of IBD in this rat model. Similar effects were seen at both doses of HGF administration, implying that there is a plateau above which further increases in HGF levels provides no added benefit. HGF administration may be clinically useful in the management of IBD.
