Abstract
Environmental pollution with the different Aluminum (Al) containing compounds has been increased. Liver and kidney are two vital organs targeted by Al accumulation. The aim of this study was to assess the possible protective and curative effects of
Linn (LS) against Al-induced impairment of liver and kidney in albino rat and to explore the mechanism behind this effect.
This experimental animal-based study included fifty albino rats divided into five groups, the control, LS-treated (20 mg/kg), AlCl
-treated (10 mg/kg), AlCl
then LS, and AlCl
plus LS-treated, simultaneously for 8 weeks. At the end of the experiment, hepatic and renal functions as well as the biomarkers of antioxidants activities were assessed in the serum. Both liver and kidney were dissected out and histopathologically examined.
This study showed that administration of AlCl
caused a significant (p<0.05) reduction in rats body weight. It significantly increased serum AST, ALT, ALP, bilirubin, urea, and creatinine levels and decreased total protein and albumin. AlCl
significantly reduced enzymatic (catalase), nonenzymatic (reduced glutathione), and ferric reducing antioxidant power (FRAP) in the serum. Histopathologically, it induced necrosis and degeneration of hepatocytes, glomeruli, and renal tubules. Administration of LS after or along with AlCl
significantly restored the serum biomarkers of liver and kidney functions to their near-normal levels and had the ability to overcome Al-induced oxidative stress and preserved, to some extent, the normal hepatic and renal structure. The coadministration of LS had a superior effect in alleviating Al-induced changes.
Exposure to AlCl
induced a set of functional and structural changes in the liver and kidney of rats evident through both biochemical and histopathological assessment. The antioxidant activity of LS seeds mediated a protective and curative effect of LS against such changes. Further study through a rigorous clinical trial to prove LS activity on human is recommended.
