    Abstract:
    ETHNOPHARMACOLOGICAL RELEVANCE: Laminaria japonica is a popular seafood and medicinal plant in China, Chinese people use them as a traditional medicine for curing edema disease, a symptom of kidney diseases. MATERIALS AND METHODS: The renal protective activity and mechanism of fucoidan derivatives was studied against adenine induced CKD in rats. The fucoidan derivatives were administered at dose of 50 and 150 mg/kg body weight. The serum urea nitrogen (SUN), serum creatinine (SCR) and some enzymic activity were detected. RESULTS: The SUN and SCR level decreased significantly with fucoidan derivatives administration. Histopathological changes of renal tubules and interstitium were markedly alleviated by fucoidan derivatives and the mesangial areas were also greatly reduced. Alterations were observed in the activities/levels of serum enzymic (CAT, GSH-PX) and non-enzymic (GSH) antioxidants, along with high level of malondialdehyde (MDA) in the CKD rats. However, normalized lipid peroxidation and antioxidant defenses occurred with fucoidan derivatives administration. CONCLUSION: This study exhibited a new mechanism of fucoidan derivatives on CKD rats, that was the samples could alleviate renal tubules, interstitium and mesangial areas mediated by replacing the electronegative content of the glomerular cells and inhibition of mesangial cell proliferation. The study also proved the mechanism of fucoidan derivatives on the CKD rats had relationship with their antioxidant activities, the samples which could enhance the activity of antioxidant enzymes and reduce the LPO level could alleviate the symptom of CKD.
