NOx levels in serum, BALF and LTH. Values are expressed as mean ± SD. Comparison between experimental groups: * p < 0.05 PREV versus ASTHMA group; ** p < 0.05 RESCUE versus ASTHMA group; *** p < 0.05 ASTHMA versus CONTROL. Abbreviations: BALF = broncho-alveolar lavage fluid; LTH = lung tissue homogenate; NOx = level of inorganic nitrites and nitrates; PREV = long-term low-dose vitamin D supplementation, RESCUE = short-term high-dose vitamin D supplementation, ASTHMA = positive control, CONTROL = negative control. Note: a Mann–Whitney test was applied for the analysis of LTH NOx values.
