Inhibitory effects of Cymodocea nodosa sulphated polysaccharide on α-amylase activity, liver-kidney toxicities and lipid profile disorders in diabetic rats.

This study aimed to evaluate for the first time the effects of Cymodocea nodosa sulphated polysaccharide (CNSP) on the α-amylase activity, hyperglycaemia, liver-kidney functions, and pancreatic architecture of alloxan-induced diabetic rats. Animals were allocated into four groups of seven rats each, the body weight and blood glucose levels were estimated periodically for 2 months of treatment by gastric gavages route. The CNSP effect was confirmed by biochemical procedures and histological study. The inhibition of α-amylase activity and protection of pancreatic β-cells induced a decrease in the blood glucose levels and regulated the lipid profile in the plasma of the treated diabetic rats, which helped to maintain the homeostasis of blood lipid. Moreover, CNSP administration induced a significant decrease in the levels of lipid peroxidation in the pancreas, liver and kidney of diabetic rats and protects their functions attested by a decrease in the levels of toxicity parameters in blood.
