Changes of main components of compound Mailuqishen and its anti-tumor effect in H22 tumor-bearing mice / 吉林大学学报(医学版)

ABSTRACT

Objective:To determine the changes of the main components after compatibility of compound Mailuqishen(MLQS), and to explore its anti-tumor effect in the H22 tumor-bearing mice.Methods:The contents of ginsenoside and amino acid in MLQS were detected by HPLC, and the content of polysaccharide was detected by phenol-sulfuric acid.A total of 144 female Kunming mice were randomly divided into normal control group, model group, positive control group, low dose of MLQS group, medium dose of MLQS group, high dose of MLQS group, ginseng geng group, ginseng group and antler plate group (n=16).Except normal control group, the mice in the other eight groups were used to establish the H22 tumor-bearing mouse models, then the mice were treated with drugs at next day.The tumor weights, inhibitory rates of tumor, spleen and thymus indexes of the H22 tumor-bearing mice were detected 10 d after administration.The morphological changes of tumor and spleen tissue were examined by HE staining, and the apoptotic rates of H22 tumor cells were tested by flow cytometry.Results:As calculation with the ginseng and antler plate single herb, the contents of ginsenosides, polysaccharides and amino acids in MLQS were significantly higher than those of single herbs (P<0.05).Compared with model group, the inhibitory rates of tumor in various administration groups were significantly increased(P<0.01);the spleen indexes and thymus indexes of the mice in different doses of MLQS groups were significantly increased(P<0.01);the apoptotic rates of tumor cells were markedly increased(P<0.05).Compared with model group, the tumor tissue of the mice in various administration groups was destroyed, the cells were sparse and irregular, and the tumor presented necrotic lesions;the morphology of spleen tissue was normal with discernible fringe, and the lymphocytes arranged densely.Conclusion:The contents of ginsenosides, polysaccharides, and amino acids in compound MLQS are significantly increased compared with those of single herbs, and its anti-tumor effect is stronger than the single herbs.
