Elevated Dengue Virus Nonstructural Protein 1 Serum Levels and Altered Toll-Like Receptor 4 Expression, Nitric Oxide, and Tumor Necrosis Factor Alpha Production in Dengue Hemorrhagic Fever Patients

Figure 2

Nitric oxide serum levels (μM of ) of patients with dengue fever (DF, ), dengue hemorrhagic fever (DHF, ), and healthy controls (HC, ) measured by Griess reaction after reduction of serum samples with nitrate reductase. Results were expressed as median using a box plot. Equivalent symbols (, #) represent statistically significant differences () between two groups.
