Fig. 2. The effect of BSE on the NO (Nitric Oxide) production of RAW 264.7 cells.The production of NO was measured by NO assay. The statistical analysis of the data was carried out by use of a t-test. ***p < 0.001 compared to control. The RAW 264.7 cells were pretreated with BSE and LPS (1 μg/mL) for 24 h (each experiment, n = 3).
