Abstract:
Objective: To examine the effect of artificial fiber complexes (AFC) on growth and RBC membrane fluidity in comparison with three single fibers. Methods: 48 healthy, female Wistar rats (50-80 g) were randomly divided into 6 groups based on body weight. All five kinds of DF (cellulose, pectin, sodium alginate, cellulose pectin complex, cellulose sodium alginate complex) were given at a level of 10% in a lipid rich diet. The control group was fed lipid rich diet alone without DF. After 8 weeks, the effect on growth and development, lipid peroxidation, RBC membrane fluidity were studied. Results: 1.All DF groups did not affect the growth and development of the rats. 2.The fecal weight and its fat content in all DF groups were significantly higher than that in control group, especially for AFC group.3. All kinds of DF could increase serum SOD and GSH Px activities and reduce MDA content (except cellulose and sodium alginate group). RBC membrane fluidity was significantly increased in DF groups, and AFC groups were the most effective. Conclusion: All these kinds of DF have the effect of increasing RBC membrane fluidity, and AFC is the best.
