[Determination of trace elements in hair of mice infected with Trichinella spiralis].

Mice were divided into 3 groups: heavy infection group with 80 mice each was fed with 400 muscle larvae of Trichinella spiralis, light infection group with 60 mice each was fed by 200 larvae, and uninfected control (60 mice) . The content of Cu, Zn and Fe in the dorsal hair samples was measured in the week of 1, 3, 5, 7, 9, 11, 13 and 15 after infection. Results indicated that the content of Zn, Cu and Fe in the two experimental groups reduced considerably in comparison to the control (P < 0.05), especially for that of Zn and Cu. Lower content was found in the heavily infected mice than in those with light infection (P < 0.05).
