Studies on Angiogenesis Inhibition Activity of Traditional Herb Extract

Angiogenesis, the formation of new blood vessels, is considered to be involved in many pathological symptoms such as diabetic retinopathy, arthritis, inflammation and solid tumour. In particular, it is thought that angiogenesis is critical for development and growth of solid tumour. Recent study shows that there is a highly significant association of microvessel density with overall survival and relapse-free survival in patients with breast tumour In this study, the inhibition effect of angiogenesis of traditional herbs used for the treatment of cancer was examined. It was found out that the extract of Agaricus blazei by boiling water is a possible inhibitor of angiogenesis. It inhibited normal developmental angiogenesis In the chorioallantoic membrane of chick embryos and also inhibited capillary-like tube formation by endotherial cells on matrigel in vitro. These results suggest that Agaricus blazei can be a potent angiogenesis inhibitor.
