The N-(2-hydroxyl) propyl-3-trimethyl ammonium chitosan chloride (HPT-chitosan) was prepared by the reaction of chitosan with glycidyl trimethylammonium chloride. The HPT-chitosan (0.75%, w/w) in diet was fed mice for 30 days. The body weights of mice in HPT-chitosan group and control group had no significant difference. The concentrations of Fe, Zn, Cu, Ca and Pb in the organs of the mice were measured...
