Figure 1.

Percentage of apoptosis in HIV-1 IIIB exposed U373 (8,000 pg/ml) and/or NAC treated compared to negative control after different times (day 1; day 3; day 5). The apoptotic cells were stained with propidium iodide (PI) and analysed by flow cytometry. The percentage of apoptotic cells was significantly lower for infected NAC-treated vs HIV treated cells. *P < 0.01 when compared vs control; §P < 0.01 when compared vs HIV-1. F: 5.84, 23.63, 32.42, respectively at day 1, 3, 5.
