This study was conducted to examine the influences of chitosan, sericin and collagen extract complexes (1:1:1, w/w/w, CSC-F-005) in blood glucose and lipid concentrations in the sera of streptozotocin (STZ, 55 mg/kg BW, IP injection)-induced diabetic rats (SD strain) fed on experimental diets for 5 weeks. The concentrations of blood glucose, total cholesterol, HDL-cholesterol, ratio of HDL-cholesterol concentration to total cholesterol, atherosclerotic index, LDL-cholesterol, free cholesterol, cholesteryl ester, triglyceride (TG) and phospholipid (PL) in serum were effective on the metabolic regulation in diabetic rats. The activities of alkaline phosphatase (ALP) and aminotransferase (AST, ALT) in serum were lower in the extract complexes (CSC-F-005) than in the diabetic rats. The results shown above suggested that CSC-F-005 extract complexes supplementation effectively improvement of blood glucose and lipid components in the serum of STZ-induced diabetic rats.

The objective of this study was to assess improvements caused by chitosan, sericin and collagen peptide extract complexes (1:1:1, w/w/w, CSC-F-005) in lipid concentrations in the sera of dyslipidemic rats (SD strain) fed on experimental diets for 5 weeks. Serum concentrations of total cholesterol, HDL-cholesterol, ratio of HDL-cholesterol concentration to total cholesterol, atherosclerotic index, LDL-cholesterol, free cholesterol, cholesteryl ester, triglyceride, phospholipid and blood glucose were effective on the metabolic regulation of dyslipidemic rats. The activities of alkaline phosphatase, aspartate aminotransferase and alanine aminotransferase in serum were remarkably lower in the extract complexes (CSC-F-005) than in the dyslipidemic model. From the above results shows that CSC-F-005 extract complexes were effective on the improvement of the lipid metabolism in sera of dyslipidemic rats.
