Abstract:

BACKGROUND: Hepatic fibrosis in chronic liver disease can be reversed. Studies have shown that Periplaneta americana extract has anti-fibrosis effect, and has protective effect on the experimental hepatic fibrosis rats.
OBJECTIVE: To observe the effect of Periplaneta americana extract sticky sugar amino acid on hepatic fibrosis, and to primarily explore the mechanism of sticky sugar amino acid against hepatic fibrosis.
METHODS: Rat models of immune hepatic fibrosis were induced by pig serum and intragastrically administered 0.5, 0.25, 0.10 g/kg sticky sugar amino acid. Four indexes of hepatic fibrosis were detected by radioimmunoassay. Immunohistochemical staining was used to measure transforming growth factor beta 1, tissue inhibitor of metalloproteinase protein expression intensity and positive cell rate, to determine the correlation of different concentrations of sticky sugar amino acid, transformation growth factor beta 1 and tissue inhibitor of metalloproteinase. 
RESULTS AND CONCLUSION: (1) The Periplaneta americana extract sticky sugar amino acid reduced the levels of laminin, type III procollagen, type IV collagen and hyaluronidase (P < 0.01) and reduced the expression of transformation growth factor beta 1 and tissue inhibitor of metalloproteinase 1 in liver tissue (P < 0.01). (2) Sticky sugar amino acid concentration and transformation growth factor beta 1 and tissue inhibitor of metalloproteinase 1 protein expression showed a significant negative correlation (| r | > 0.9). (3) Results confirmed that the Periplaneta americana extract sticky sugar amino acid can change the reversal of hepatic fibrosis. Its mechanism of action is associated with expression of transforming growth factor beta 1 and tissue inhibitor of metalloproteinase 1 inhibited by sticky sugar amino acids.
