Pathophysiological significance of a reaction in mouse gastrointestinal tract associated with delayed-type hypersensitivity

Table 1 Effect of DNCB enema on LMIF activity in sensitized mice

Group	Skin smearing (50 μL/mouse)	Enema (2 μL/g bm)	A value (mean ± SE)
Control	Acetone-olive oil	600 mL/L ethanol	0.426 ± 0.009
DTH(-)	Acetone-olive oil	2 g/L DNCB	0.401 ± 0.007
DTH4	33 g/L DNCB	1 g/L DNCB	0.383 ± 0.038
DTH5	33 g/L DNCB	2 g/L DNCB	0.220 ± 0.012b
DTH6	33 g/L DNCB	4 g/L DNCB	0.139 ± 0.019d

^bP < 0.01 when compared with the control and DTH_(-) (student’s t-test).

^dP < 0.01 between DTH₄, DTH₅ and DTH₆ groups (ANOVA); n = 9 in each group. A, the absorbance of migration leukocytes. The skin smearing and enema were completed daily for 4 d.
