  • The role of apurinic/apyrimidinic endonuclease1/redox factor-1 (Ref-1) on the lead (Pb)-induced cellular response was investigated in the cultured endothelial cells. Pb caused progressive cellular death in endothelial cells, which occurred in a concentration- and time-dependent manner. However, Ref-1 overexpression with AdRef-1 significantly inhibited Pb-induced cell death in the endothelial cells. Also the overexpression of Ref-1 significantly suppressed Pb-induced superoxide and hydrogen peroxide elevation in the endothelial cells. Pb exposure induced the downregulation of catalase, it was inhibited by the Ref-1 overexpression in the endothelial cells. Taken together, our data suggests that the overexpression of Ref-1 inhibited Pb-induced cell death via the upregulation of catalase in the cultured endothelial cells.

  • The aim of the present experiments was to investigate the effect of Palmijihwangtang water extracts on the plasma renin activity and plasma levels of atrial natriuretic peptide and aldosterone in rats. The results of this study were as follows 1. Plasma renin activity was not different after the administration of Palmijihwangtang water extracts 2. Plasma levels of aldosterone decreased significantly after the administration of Palmijihwangtang water extract 3.0 ml/kg. 3. Plasma levels of atrial natriuretic peptide (ANP) decreased significantly after the administration of Palmijihwangtang water extracts.
