Abstract
Lead (Pb) exposure is a global environmental problem that can deplete body antioxidant enzymes, causing damage to various macromolecules and ultimately cell death. Pb exposure could lead to serious renal damage. Baicalin, a traditional Chinese medicine, could protect against renal injury through inhibition of oxidative stress and apoptosis. This study was designed to investigate the protective efficacy of baicalin against Pb-induced nephrotoxicity in mice and to elucidate the potential mechanisms using animal experiment. The results revealed that baicalin decreased Pb-induced bodyweight loss, declined kidney coefficients, and ameliorated renal function and structure in a dose-dependent manner. Meanwhile, baicalin dose dependently increased Pb-induced activity of SOD and GSH-Px, while the content of MDA in the kidney was decreased. In addition, baicalin enhanced the Bcl-2/Bax ratio associated with apoptosis in the kidney. These data indicated that further investigation of the use of baicalin as a new natural chemopreventive agent against Pd poisoning is warranted.
