Abstract:
Objective To comparative study of the immunomodulatory effects of Hedysarum polybotrys polysaccharides (HPS) etc.four species TCM polysaccharides on immunocompromised mice model made by cyclophosphamide.Methods Low-immunity model mice made by cyclophosphamide 40 mg · kg-1.The KM mice were divided into seven group:normal,model,control,experimental-HPS,experimental-Astragalus polysaccharides (ASPS),experimental-Codonopsis pilosula polysaccharides (CPS) and experimental-Angelica polysaccharides (ANPS) groups randomly.The control group was administrated Shenqi particle 5 g · kg-1.The other tested groups were administrated the corresponding test samples 2 g · kg-1.The normal and model group were administrated the same quantity of normal saline.Give the medicine 1 time each day for 15 days.The visceral index was counted by weighted.The peritoneal macrophage phagocytic count by intraperitoneal injection 5％ chicken red blood-cell were meaeured (OD value).The serum hemolysin OD through delayed type hypersensitivity maded by 50％ dinitrochlorobenzene.The reticuloendothelial system phagocytic count were meaeured by caudal vein injection carbon inkl.Results Compared with the normal,the difference of all indexs of model were statistically significant(all P ＜ 0.01).After dosing,the thymus indexs of model,control,experimental-HPS,experimental-ASPS,experimental-CPS and experimental-ANPS groups were 2.55 ± 0.88,1.04 ± 0.74,2.00 ± 0.89,2.21 ±0.95,1.92 ±0.43,1.67 ±0.41.Compared with the model,difference of experimental-HPS,experimental-ASPS and experimental-CPS were statistically significant (all P ＜ 0.05).The phagocytic counts of mouse peritoneal macrophages of the six groups were 1.31 ±0.18,0.51 ±0.12,1.12 ±O.13,1.19 ±0.09,0.88 ±0.25,0.72 ±0.07.Compared with the model,difference of four species polysaccharides were all statistically significant (all P ＜ 0.01).Compared with the experimental-ANPS,difference of experimental-HPS and experimental-ASPS were statistically significant(P ＜ 0.05,P ＜ 0.01).The phagocytic coefficient of reticuloendothelial system phagocytosis of the six groups were 6.60 ± 0.94,0.99 ±0.83,0.32 ± 1.48,7.28 ± 2.13,5.29 ± 1.97,5.93 ± 1.75.Compared with the model,difference of experimental-HPS and experimental-ASPS were statistically significant (P ＜ 0.05 or P ＜ 0.01).The delayed type hypersensitivity OD of the six groups were 0.53 ± 0.16,0.23 ± 0.09,0.36 ± 0.09,0.38 ± 0.12,0.29 ± 0.10,0.33 ± 0.11.The serum hemolysin OD of the six groups were 0.60 ± 0.12,0.43 ± 0.10,0.53 ± 0.08,0.54 ± 0.11,0.51 ± 0.11,0.52 ± 0.09.Compared with the model,difference of experimental-HPS,experimental-ASPS and experimental-ANPS were statistically significant (P ＜ 0.05 or P ＜ 0.01).Conclusion These four kinds of polysaccharides have the function of enhancing nonspecific immunity function,specific humoral immunity and cellular immune function in mice.HPS and ASPS were more comprehensive and significant for the regulation of immune indexes than CPS and ANPS.
