Effect of North American Ginseng on 137Cs-induced Micronuclei in Human Lymphocytes
Lee, Tung-Kwang; Wang, Weidong; O'Brien, Kevin F.; Roberta, Johnke; Allison, Ron R.; Diaz, Angelica; Wang, Tao (East Carolina University, 2008-12)To explore the radioprotective effect of a standardized North American ginseng extract (NAGE) on human peripheral blood lymphocytes (PBL), a micronuclei (MN) assay was conducted in PBL obtained from 12 volunteers. NAGE ... -
