Figure 3: Effects of Danshen on DTH responses. After two immunizations with KLH for assessment of antibodies to KLH, BALB/c mice received a footpad challenge (100 μg KLH in 25 μL saline) 21 days after the second immunization. The DTH response was measured 24 hr later. Results of the 0% ( ), 0.5% ( ), 1% ( ), and 2% ( ) Danshen are shown as mean ± SD; *indicates that the 1% Danshen group significantly differs from the 0% and 0.5% groups.
