Objective: The purpose of our study was to show the effects of Hwalhyulmaksung-bang (Huoxiemoxing-fang, HHMSB) treatment on cBSA-induced in MN Mouse Model. Methods: We divided the 20 mice into 4 groups. One group, named NR, was not treated. The second group, named CT, was treated with cBSA (7mg/kg i.p) only. The third group, named HH-250, was treated with cBSA (7mg/kg i.p) and HHMSB extract (250mg/kg, p.o). The fourth group, named HH-500, was treated with cBSA (7mg/kg i.p) and HHMSB extract (500mg/kg, p.o). 4 weeks after cBSA, proteinuria, serum albumin, total cholesterol, serum creatinine, BUN, total cell number of spleen and kidney of all groups were measured. CD3e+/CD19+ and CD4+/CD8 cells ratio of peripheral blood, kidney and spleen of all groups were analyzed. $IL-1{eta}$ and TNF-$alpha$, IL-6, IgG, IgM, and IFN-$gamma$ levels of all groups were gauged. Histological analysis of kidney tissue and immunohistochemical staining (CD4, CD8) of kidney were observed. Results: The level of proteinuria significantly decreased and serum albumin increased in the group treated with cBSA and HHMSB extract compared with the control. Total cholesterol decreased but not significantly. CD3e+/CD19cells ratio of peripheral blood is decreased, but CD4+/CD8cells ratio has no significancy. CD3e+/CD19+ and CD4+/CD8 cells percentage of kidney and spleen has no significancy. Level of $IL-1{eta}$, IL-6 is significantly decreased, and IFN-$gamma$ is significantly increased on HHMSB compared with control. Total IgG level significantly decreased on HHMSB compared with the control. Thickness of GBM decreased on histological analysis of kidney. Deposition of CD4 and CD8 decreased on immunohistochemical staining of kidney. Conclusions: We conclude that Hwalhyulmaksung-bang treatment may could be a useful remedy agents for treating Membranous Neuropathy(MN) induced by cationized bovine serum albumin.
