The Cancer-Preventive Potential of Panax ginseng - A Review of Human and Experimental Evidence -

Abstract: Objective : We have reviewed the potential cancer preventive and other relevant properties of Panax ginseng C A Meyer, which has been traditionally used as a natural tonic in oriental countries Data identification and study selection: Publications on Panax ginseng and its relation to cancer were obtained from the Medline database (1983-2000) and by checking reference lists to find earlier reports The reports cover experimental models and human studies on cancer-preventive activity, carcinogenicity and other beneficial or adverse effects In addition, possible mechanisms of chemoprevention by ginseng were also considered Results : Published results from a cohort and two case-control studies in Korea suggest that the intake of ginseng may reduce the risk of several types of cancer When ginseng was tested in animal models, a reduction in cancer incidence and multiplicity at various sites was noted Panax ginseng and its chemical constituents have been tested for their inhibiting effect on putative carcinogenesis mechanisms (eg, cell proliferation and apoptosis, immunosurveillance, angiogenesis); in most experiments inhibitory effects were found Conclusion : While Panax ginseng C A Meyer has shown cancer preventive effects both in experimental models and in epidemiological studies, the evidence is currently not conclusive as to its cancer-preventive activity in humans The available evidence warrants further research into the possible role of ginseng in the prevention of human cancer and carcinogenesis

Blood Lead, Manganese, Aluminium and Silicon Concentrations in Korean Adults

Abstract: Objectives : This study was peformed to determine the reference values of blood lead, manganese, aluminium, and silicon in healthy adults Methods : The subjects were 132 (67 male and 65 female), and classified to three age groups Blood lead, manganese and aluminium were analyzed by atomic absorption spectrophotometer, and blood silicon was analyzed by direct current plasma optical emission spectrometer Results : Blood lead levels(geometric mean, SD) were (349, 170) in male and (304, 165) in female, but the difference is not significant, and there was no significant difference between age groups Mean blood manganese level was , and there was no significant difference between sex or age groups Mean blood aluminium level was , and there was no significant difference between sex or age groups Mean blood silicon level was in male and in female, and the level in male was significantly higher than that in female (p
