American Ginseng Modifies 137Cs-Induced DNA Damage and Oxidative Stress in Human Lymphocytes
Lee, Tung-Kwang; O'Brien, Kevin F.; Wang, Weidong; Sheng, Chao; Wang, Tao; Johnke, Roberta M.; Allison, Ron R. (East Carolina University, 2009-01-01)The multifold bioactive medicinal properties of ginseng have been closely linked to its antioxidative ability, which is related to its ginsenoside content. Since the key mechanism of radiation-induced cell death and tissue ... -
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 ... -
Identification of Extracellular d-Catenin Accumulation for Prostate Cancer Detection
Lu, Qun; Zhang, Jiao; Allison, Ron R.; Gay, Hiram A.; Yang, Wan-Xi; Bhowmick, Neil; Frelix, Gloria; Shapell, Scott; Chen, Yan-Hua (East Carolina University, 2009-03-01)BACKGROUND—Prostate cancer is the second leading cause of cancer death in men, and early detection is essential to reduce mortality and increase survival. δ-Catenin is a unique β-catenin superfamily protein primarily ... -

Radioprotective Effect of American Ginseng on Human Lymphocytes at 90 Minutes Post-irradiation: A Study of 40 Cases
Lee, Tung-Kwang; O'Brien, Kevin F.; Wang, Weidong; Johnke, Roberta M.; Sheng, Chao; Benhabib, Sidi Mohammed; Wang, Tao; Allison, Ron R. (East Carolina University, 2010-05)Backgroundâ Ionizing radiation (IR) initiates intracellular oxidative stress through enhanced formation of reactive oxygen species (ROS) that attack DNA leading to cell death. As the diversity of IR applied in medicine, ... -
