- The quantitative scoring of each cytokine on the epithelium was as follows: score 1: positive staining in the cytoplasma of epithelial cells only on the upper 1/3 part of the epithelium; score 2: on the upper and middle part of the epithelium (1/3–2/3); score 3: on the whole layer of the epithelium (> 2/3). The positive staining of each cytokine on the lamina propria (lymphocytes, fibrocytes, and neutrophils) means there were more than five positive cells in a high power field of view in the microscopic examination.
