Experimental Study of WhaYoungJiTongTang(Heyingjitongtang)on the anti-angionesis

화영지통탕(和營止痛湯)의 혈관신생억제효과(血管新生抑制效果)에 관한 실험적(實驗的) 연구(硏究)

The purpose of this study is to prove the angiogenesis effects of WhaYoungJiTongTang (hereinafter referred to as the 'WYJTT'). For the study, by utilizing liver cancer cell line; SK-HEP-1, lung cancer cell line: A549, stomach cancer cell line: AGS and bovine capillary endothelial cell: BCE, the effects of the WYJTT on toxicity and proliferation ability of cells and the effects on anti-angiogenesis of bovine capillary endothelial cell and of mice's aorta were studied. 1. Cell viability assay In comparison with the control group, when $100{\mu}g/ml$ of WYJTT was injected, the viability was reduced in SK-Hep-1, $400{\mu}g/ml$ in A549 and $200{\mu}g/ml$ in AGS. 2. Cell proliferation assay In comparison with the control group, when $600{\mu}g/ml$ of WYITT was injected, DNA synthesis was reduced to 35.1% in the SK-Hep-1, 56.0% in A549, and 25.8% in BCE (bovine capillary endothelial cell); and when $400{\mu}g/ml$ was injected, DNA synthesis was reduced to 12.1 in AGS. 3. Tube formation assay In the event that BCE is injected with WYJTT in each of its content gradient, the anti-angiogenesis was effective in amounts of $400{\mu}g/ml$ with 6 hours of the treatment. 4. Aortic ring assay In comparison with the control group, the angiogenesis was restricted to the remarkable degree in amount of $200{\mu}g/ml$: 10% in $400{\mu}g/ml$; and fully inhibited in each of $800{\mu}g/ml$ and $1600{\mu}g/ml$. As a result of the experiments mentioned above, WYJTT showed its anti-angiogenesis effects against cancer cell line.
