Objectives: This paper is to investigate what effects Yeonryunggobondan and Palmijihwangtang have on postponing senility in rat fibroblasts, heart-endothelial cells, mesangial cells. Methods: 1. In vitro Yeonryunggobondan and Palmijihwangtang controlled the growth of fibroblasts, heart-endothelial cells, mesangial cells, extended the PDT of them. 2. After feeding rats the drugs for 2 months, the fibroblasts, heart-endothelial cells, mesangial cells were cultured. Results: 1) In fibroblasts the PDN was incresed and the PDT was decreased at passage-1, 2 by Yeonryunggobondan and Palmijihwangtang(p<0.05). 2) In heart-endothelial cells the PDN was incresed and the PDT was decreased at passage 8 by Yeonryunggobondan and Palmijihwangtang(p<0.05). 3) In mesangial cells the PDN was increased and the PDT was decreased at passage 4 by Yeonryunggobondan, the PDN was incresed at passage 4 by Palmijihwangtang(p<0.05). Conclusions: It is concluded that both Yeonryunggobondan and Palmijihwangtang maybe be conductive to protect and delay the senescence of rat fibroblasts, heart-endothelial cells, mesangial cells.
