[The immunomodulatory effects of sijunzi decoction and its disassembled prescription on D-galactose-induced aging mice]

Abstract

Objective: To observe the immunomodulatory effects of codonopsis, atractylodes macrocephala, tuceahoe, broiled licorice and sijunzi decoction on D-galactose-induced aging mice.

Methods: The models of aging mice were induced by D-galactose, the garlands and splenic lymphocyte transformation test (MTT) were used to determine the ability of erythrocytes immune and lymphocytes conversion; The content of maleic dialdehyde (MDA), activity of superoxide dismutase (SOD) and glutathione pemfidase (GSH-Px) in serum were detected.

Results: Sijunzi decoction and its disassembled prescription codonopsis could significantly increase the ability of T lymphocyte transformation (P<0.05); Atractylodes macrocephala and sijunzi decoction could significantly enhance C(3b) garlands ratio (P<0.05) and decrease IC garlands ratio (P<0.05) on D-galactose-induced aging mice. Sijunzi decoction significantly increased the activity of SOD and GSH-Px (P<0.01), and decreased the content of MDA in serum (P<0.05).

Conclusion: Sijunzi decoction and its disassembled prescription codonopsis, atractylodes macrocephala can improve the immunomodulatory effects on D-galactose-induced aging mice; but tuceahoe and broiled licorice have no obvious effects.
