Potential protective effects of the edible alga Arthrospira platensis against lead-induced oxidative stress, anemia, kidney injury, and histopathological changes in adult rats.
Appl Physiol Nutr Metab. 2019 Mar; 44(3):271-281.AP

Abstract

Oxidative damage has been proposed as a possible mechanism involved in lead toxicity. This study investigated the possible protective effect of dietary Arthrospira platensis supplementation against lead acetate-induced kidney injury in adult male rats. Rats were divided into 4 groups: normal rats (control rats), rats treated with spirulina, rats treated with lead (Pb) (0.344 g/kg body weight), and rats treated with Pb and spirulina. The exposure of rats to Pb for 30 days provoked renal damage with significant increases in hematological parameters, oxidative stress-related parameters (i.e., thiobarbituric acid reactive substances, protein carbonyl content, advanced oxidation protein products, and hydrogen peroxide), creatinine and urea levels in plasma, and uric acid level in urine. Conversely, antioxidant enzyme activities (i.e., catalase, glutathione peroxidase, and superoxide dismutase) and levels of nonprotein thiols, plasma uric acid, and urinary creatinine and urea decreased. The administration of spirulina to Pb-treated rats significantly improved weight, peripheral blood parameters, oxidative stress-related parameters, renal biomarker levels, and antioxidant enzyme activities. Also, rats treated with Pb and spirulina had normal kidney histology. These healing effects are likely the result of the high phenol content and significant antioxidant capacity of A. platensis. Our data strongly suggest that spirulina supplementation improves kidney function and plays an important role in the prevention of complications of Pb intoxication.
