Effect of lithium chloride on d-galactose induced organs injury: Possible antioxidative role.

The aging process is concerned with oxidative stress and causing malfunction of various organs such as the liver, kidney and heart. Lithium (Li) salts have shown anti-manic, anti-suicidal, and antioxidant properties. The current study is aimed to evaluate the possible inhibitory effects of various doses (10, 20 & 40mg/ml/kg) of Lithium chloride (LiCl) on D-galactose (D-gal)-produced aging model and explore the underlying mechanism. In the study 40 male rats were randomly alienated into 8 groups i.e. saline, LiCl (10, 20 & 40mg/ml/kg), D-gal and D-gal+LiCl (10, 20 & 40 mg/ml/kg). D-gal was given at a dosage of 300mg/ml/kg$ and animals received their respective treatment for 6 weeks [intraperitoneally (I.P), once daily]. After 2 weeks animals were decapitated and organs (liver, kidney, and heart) were removed for antioxidant assays. Blood was also collected for biochemical parameters. LiCl substantially decreased oxidative strain marker and increased enzymatic antioxidants in the liver, kidney, and heart of D-gal treated rats. LiCl also decreased serum alanine aminotransferase (ALT), aspartate transaminase (AST), creatine, urea, CK-MB, triglyceride, cholesterol, low-density lipoprotein (LDL) and increased high-density lipoprotein (HDL) in D-gal treated animals. High dose (80mg/ml/kg) of LiCl observed as the most effective dose against D-gal induced alterations. These finding LiCl inhibits D-gal induced liver, kidney and heart damages via its antioxidant potential.
