N = Naive, S = Sensitised, DEX = Dexamethasone, SAPE = Sensitised water propolis extract, SE = Sensitised ethanol, SEPE = Sensitised ethanolic propolis extract, SH = Sensitised honey, SRJ = Sensitized royal jelly.

1+ = focal inflammation.

2+ = all around inflammation (<5 layers cells deep).

3+ = all around inflammation (>5 layers cells deep).

P = probability.

S = significance.

a = significant increase in inflammatory cells comparable to the naive group.

b = significant decrease in inflammatory cells comparable to the sensitised group.
