Figure 4. 8-hydroxy-2′-deoxyguanosine (8-OHdG) concentration in rectal dialysis in HIV-negative and positive children.

The determinations of rectal 8-OHdG production were performed using a dialysis bag (A) in serum-negative (n = 6, SN) and positive (n = 20, HIV+) children (B). *p<0.05 vs SN. (C) HIV+ children were divided in two groups and compared with controls (n = 6, white): HIV RNA >40cp/ml (n = 9, black), HIV RNA <40cp/ml (n = 11, grey). *p<0.05 vs RNA <40cp/ml and SN groups.
