^aThe medians of the fluorescence intensities (n = 3) measured on day 1 were 1.40 × 10¹, 9.33 × 10⁰, 1.87 × 10¹, and 2.23 × 10¹ U/cell in the duodenum, jejunum, ileum, and colon respectively. <1/4 median, lower than one fourth of the median fluorescence intensity measured on day 1; 1/4-1/2 median, one-fourth to one-half of the median intensity; 1/2-median, half of median to median intensity; >median, higher than median intensity.
