Wastewater emissions are increasing by economic growth and development of the industry, and it is the main cause of water pollution. Dyeing wastewater discharge accounts for 8% of industrial wastewater emissions, and since it contains hardly decomposable substances, advanced treatment is necessary. Thus, dyeing wastewater was treated by an electrochemical method(Electro-coagulation) using aluminum as anode and stainless steel 316 as cathode of experiments were carried out in a batch type. Operation parameters, such as current density (20, 40, 60 A/m<sup>2</sup>), effect of electrolyte (NaCl, Na<sub>2</sub>SO<sub>4</sub>) were investigated for their influences on T-N removal efficiencies. Under the condition without electrolyte, when the current density was adjusted to 20 A/m<sup>2</sup>, 40 A/m<sup>2</sup> and 60 A/m<sup>2</sup>, removal efficiency of T-N was 38.4%, 53.1% and 66.2% at 60min. In comparison with condition of adding NaCl and non-addition, the removal efficiency of adding NaCl was higher 20% on average than non-addition of all current density. In comparison with condition of adding Na<sub>2</sub>SO<sub>4</sub> and non-addition, the removal efficiency of adding Na<sub>2</sub>SO<sub>4</sub> was higher 10% or less on average than non-addition of all current density.

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.

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.
