(a) Levels of mRNA for iNOS and eNOS quantified using RT-qPCR in patients without reflux (NR) and with reflux (R) and by their ages. Results are expressed as arbitrary units. . (b) Distribution of the percentage of patients with positive protein expression for iNOS and eNOS in patients without reflux (NR) and with reflux (R) and by age, . (c) Protein expression images of iNOS in (A), (B, C), (D), and (E) patients. (d) Protein expression images of eNOS in (A), (B), and (C) patients. The arrows are the brown coloration indicating the specific precipitate that correlates with the expression of the said protein.
