Effects of chronic stress on bacterial passage
| Group, tissue | 45 min passage | 90 min passage | 120 min passage |
|---|---|---|---|
| Rats were subjected to water avoidance stress (WAS) or sham stress (SS) for 10 days, 1 h/day, 6 rats/group. Segments of villus epithelium (VE) and follicle associated epithelium (FAE) were mounted in Ussing chambers. Passage of chemically killed E coli K-12 was studied over time. | |||
| Values are presented as median (25–75th interquartile range). | |||
| Comparisons between groups were performed using Kruskal-Wallis one way ANOVA: *p<0.005 versus SS FAE; †p<0.05 versus WAS VE; ‡p<0.05 versus SS VE. | |||
| WAS, FAE | 0.6 (0.3–1.2) | 4.3 (2.0–5.9) | 47.9 (17.6–94.7)* † |
| SS, FAE | 0.0 (0.0–0.0) | 1.8 (1.2–2.2) | 1.4 (0.9–5.1) |
| WAS, VE | 0.4 (0.1–0.7) | 2.2 (1.5–7.3) | 7.8 (6.4–19.3)‡ |
| SS, VE | 0.6 (0.4–1.4) | 3.9 (3.6–4.2) | 5.0 (3.0–5.8) |
