유산균 발효된 매자나무 추출물이 마우스 혈청중의 Melatonin 및 Serotonin의 함량에 미치는 영향

초록

This study was to investigate the effect of fermentation extracts on the concentration of serotonin and melatonin in the serum of the ICR mice. The ICR mice were divided into water control group, lactobacillus fermentation solution including (Lactobacillus paracasei and Bifidobacterium longum B6) control group, positive control group (milk and doxylamine succinate), negative control group (caffein) and the groups treated with the extracts of Berberis koreana bark (WE:water extracts, FE-L.P: fermentation extracts of Lactobacillus paracasei, FE-B.L: fermentation extracts of Bifidobacterium longum B6). After ten-day feeding treatment, the mean concentration of serotonin for water control, WE, FE-L.P and FEB. L group was 134.72, 183.01, 232.09 and 223.78 ng/㎖, respectively. The mean concentration for FE-L.P and FE-B.L group were approximately 66% larger than that for water control group. The mean concentration of melatonin for water control,WE, FE-L.P and FE-B.L group was 76.92, 106.66, 157.56 and 141.81 pg/㎖, respectively. The mean concentration of melatonin for FE-L.P and FE-B.L group were also larger than that for water control group. Our results indicated that the fermentation extracts of Berberis koreana bark have relatively greater potential to induce secretion of serotonin and melatonin. Therefore, the fermentation extracts have antidepressant effect.
