Table 1. Percentages of the PAS Stained Mucus Grades in Nasal Tissues of Normal, Sham and Allergenized Mice and Allergic Mice after Receiving Vaccines and Placebo.

Group of mice (Total microscopic fields)	% mucus grade^*
	Grade 1	Grade 2	Grade 3
Normal (31)	83.87^a	16.13^a	0^a
Cat CE allergenized (23)	56.52^b	26.09^a	17.39^b
Sham (53)	81.13^a	18.87^a	0^a
L-P (78)	48.71^a	23.08^a	28.21^a
L-cCE (92)	55.44^a	42.39^b	2.17^b
L-nFD1 (55)	47.27^a	40.00^b	12.73^b

L-P, L-cCE and L-nFD1 are allergic mice after receiving placebo and vaccines (5 mice per group). Five to twenty microscopic fields (400×) of the mucus glands in the stained nasal tissues were graded according to the color intensities.

^* Percentages of individual PAS stained mucus grades were analyzed by Chi-square test.

Entries with different superscripts along vertical axis (a versus b) are statistically different at p < 0.05.
