Fig. 7. IL-10 and IL-4 in supernatant from PBMC obtained from middle-aged men and incubated with PHA (5 µg/mL) plus media, the dietary supplement (containing androstenedione and DHEA at 10^-7 M), androstenedione (10^-7 M) or DHEA (10^-7 M). Results are expressed as mean ± SEM. Asterisk indicates significant difference (p < 0.05) between cultures containing media alone and cultures containing dietary supplement. A trend (p < 0.1) towards a difference between cultures containing media alone and cultures containing DHEA or androstenedione is indicated by +.
