Results are expressed as mean±SD.

Means with different letters (a,b) are significantly different at P<0.05.

NC, normal control; C, DNCB-control; PC, positive control (DNCB-treated NC/Nga mice fed a disupplement of 240 mg/kg b.w. of γ-rinolenic acid); lactic acid bacteria strains (LBS) from kimchi [DNCB-treated NC/Nga mice fed a dietary supplement of 2×10⁴ CFU/mouse of LBS isolated kimchi].

¹⁾Weight gain (g/2 weeks)=final body weight (g)−initial body weight (g).

²⁾Food efficiency ratio=weight gain (g)/total food consumption (g)×100.
