Figure 1: Comparison of the PHA-cultures. HKBA addition downregulates (a) the percentages of CD4+/CD25+ T-cells in all groups and (b) CD14+/CD80+ monocytes in brucellosis patients. Data represent mean values+SD (SE). #P  ≤  .05; PHA versus PHA  +  E. coli LPS,   ≤  .05;   <  .001; PHA versus PHA  +  HKBA, *P  ≤  .05; **P  <  .001; PHA  +  E. coli LPS versus PHA  +  HKBA.
