We elucidated that blood coagulation system and IFN-γ(Interferon-gamma), PAI-1(Plasminogen activator inhibitor-1) controlled the adhesion, desmoplasia by operation adhesion mechanism analysis. From this analysis, we hypothesized that blood coagulation system, IFN-γ, PAI-1 played an important role in liver fibrosis and inspected it by the PAI-1 knockout mice, and it was suggested that PAI-1 and t-PA （tissue plasminogen activator) affected liver fibrosis but IFN-γ did not contribute so much using a mouse model that was ligated bile duct.

通过手术黏附机理分析，阐明了凝血系统和IFN-γ（干扰素-γ）、PAI-1（纤溶酶原激活物抑制剂-1）对粘连、结缔组织形成的控制作用。从这个分析中，我们假设凝血系统、IFN-γ、PAI-1在肝纤维化中起重要作用，并通过PAI-1敲除小鼠对其进行了检测，并且在结扎胆管的小鼠模型中，我们提出PAI-1和t-PA（组织纤溶酶原激活剂）影响肝纤维化，但IFN-γ的作用没有那么大。
