RESUMEN
Objective To investigate the immunomodulatory effects of lyophilized royal jelly ( LRJ) on immunoglobulin IgG,IgA,IgM and complement C3 and C4 in patients with low immunity ,and to evaluate the clinical efficacy of LRJ.Methods A self-controlled clinical study of immunomodulatory efficacy of LRJ was performed in 32 patients with low immunity.Every patient took orally LRJ,two times a day.The hepatic function AST,ALT,and immunoglobulin IgG,IgA,IgM and complement C3,C4 were assayed after treatment for 28 days,and then the efficacy and safety of LRJ were evaluated.Results After took orally LRJ,the levels of IgG,IgA,and IgM [(10.31 ±2.03)g/L, (1.69 ±0.55)g/L,(1.51 ±0.55)g/L] were significantly higher than those before treatment [(8.52 ±1.94)g/L, (1.38 ±0.57)g/L,(1.36 ±0.55)g/L](t=5.21,2.25,1.56,all P0.05).Conclusion LRJ can increase the levels of immu-noglobulin IgG,IgA and IgM,thus to improve the symptoms of patients with low immunity .
