LAMB2 and hepatitis B virus infection: Salvia injection and salvianolic acid B, have been tested in patients infected with hepatitis B. Salvianolic acid B, administrated over 6 months, reversed liver fibrosis and inflammation more effectively than IFNγ in patients with hepatitis B, as suggested by significant improvement in serum hyaluronic acid, laminin, type IV collagen, and procollagen III peptide as compared with the IFNγ group [194].
