(n-3) PUFA | (n-6) PUFA | ||
---|---|---|---|
Induration diameter, mm | |||
Preinfection | 3.2 ± 1.7* | 11.4 ± 3.2 | |
3 Wk postinfection | 0.87 ± 0.87** | 11.4 ± 2.8 | |
6 Wk postinfection | 15.4 ± 4.1*** | 34.5 ± 1.7 |
Values are means ± SEM, n = 5–10. Asterisks indicate different from (n-3) PUFA: *P = 0.03,**P = 0.003, ***P = 0.0008. Results shown were obtained 24 h following PPD injection.
