Effect of orally administered EBN on the secretion of intestinal sIgA

Group	Intestinal sIgA (µg/mL)
Control	13.83±0.99
Model	8.26±1.09**
EBNL + model	10.50±1.80**,##
EBNM + model	12.87±1.38##
EBNH + model	11.04±1.82**,##

Notes: The lumen of the proximal 10 cm of the small intestine was washed with 3 mL PBS. After centrifugation (4°C, 3,000× g for 10 minutes), the supernatant was frozen at −80°C until use. Measurement of total IgA was performed using a sandwich-type ELISA. The data are the mean ± SD (n=6/treatment).

^**Significant difference from control group (P<0.01).

^##Significant difference from CY group (P<0.01).

Abbreviations: EBN, Edible bird’s nest; EBNL, EBN low dose; EBNM, EBN medium dose; EBNH, EBN high dose; ELISA, enzyme-linked immunosorbent assay; SD, standard deviation; PBS, phosphate buffered saline; CY, cyclophosphamide.
