Abstract
High fat diet (HFD) exposure is associated with various pathological dysfunctions, including haematological disorders and oxidative stress. The in vitro analysis of AECG revealed the presence of important levels of polyphenols and flavonoids, and denoted antioxidant capacities confirmed by nitric oxide radical (NO

), reducing the power and HPLC chemical components' determinations. The animals exposed to HFD revealed a severe damage in the blood cells structure and haematological parameters accompanied with a significant decrease in serum Mg

and Ca

ATPase activities. Furthermore, malondialdehyde (MDA) and the advanced oxidation of protein products (AOPP) levels were significantly increased, while vitamin C level, superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities were markedly reduced in the erythrocytes and platelets of HFD-treated mice. However, the co-administration of AECG with HFD-treated animals restored the parameters cited above to near-normal values. Therefore, our investigation revealed that Chaetomorpha gracilis extract was a useful element preventing HFD-induced blood cells damage.
