Abstract

Abstract:

In order to investigate immunoregulation functions of pupa polypeptides, mice were randomly divided 3 groups and conducted to oral administration of pupa polypeptides at the doses of 5.0, 1.7 g/kg·d and 0.6 g/kg·d for 40 days, respectively. Changes in immune organ index, delayed-type hypersensitivity (DTH), number of antibody-producing cells and carbon clearance capability were examined to evaluate immune functions. Results indicated that pupa polypeptides could significantly improve thymus index, promote plantar swelling, increase the generation of antibody-producing cells and enhance capability of monocyte-macrophage phagocytosis. Therefore, pupa polypeptides exhibited a significant effect on improvement of immune functions in mice.

Key words: pupa protein, polypeptide, immunoregulation effect
