Figure 3. NO-np decreases subcutaneous abscess area in mice.

(A) Abscesses of Balb/c mice untreated MRSA-infected, np-treated MRSA-infected, and MRSA-infected treated with NO-np, day 4. Arrows denote abscesses. Inset shows a representative purulent abscess 4 days after MRSA infection. Scale bar: 5 mm. (B) Abscess area analysis of Balb/c mice subcutaneous lesions. Abscesses were infected with MRSA and untreated or treated in the absence or presence of NO. Each point represents an abscess. Dashed lines are the averages of the results for fourteen measurements, and error bars denote standard deviations. Asterisks denote P value significance (** P<0.001) calculated by analysis of variance and adjusted by use of the Bonferroni correction.
