The effects of anti-stress mind tonic (ASMT) drink (ASMT-0.1% and ASMT-0.5% concentration) were tested for the anti-stress action. ICR male mice (20$\pm$2 g) were fed with basic experimental diets free access to water containing these ingredients for 18 days. Psychological stress/sociopsychological stress were exposed by foot-shock for 1 hour for 3 days. Both ASMT-0.1 and ASMT-0.5 groups in the sociopsychological stress resulted in a significant decrease of 19.1% and 41.9% in plasma corticosterone (CS) secretion compared with psychological stress (control group). Noradrenaline (NA) secretions in the brain were significantly increased 23.4% and 35.9%, respectively, in ASMT-0.1 and ASMT-0.5 groups compared with control group. MHPG-SO4 (3-Methoxy-4-hydroxyphenylethyleneglycol sulfate) levels in the brain resulted in a marked decreases of 27.1% and 19.6%, respectively in ASMT-0.1 and ASMT-0.5 groups. NA/MHPG-SO4 ratios in the brain of ASMT-0.1 and ASMT-0.5 groups resulted in a significantly increase of about 70% compared with control group. These suggest that mind tonic anti-stress drink can effectively ridded the sociopsychological stress.

The effects of anti-stress rose fruit (ASRF) extract drink (ASRF-0.1% and ASRF-0.5% concentrations) were tested for the anti-stress action. ICR male mice (20$\pm$2 g) were fed with basic experimental diets and given free access to water containing these ingredients for 18 days. Psychological stress/sociopsychological stress exposed by foot-shock for 1 hour for 3 days. Both ASRF-0.1 and ASRF-0.5 groups in the sociopsychological stress resulted in a significant decrease of 24.3% and 38.0% in plasma corticosterone (CS) secretion compared with psychological stress (control group). Noradrenaline (NA) secretion in the brain were significantly increased 35.9% in ASRF-0.5 group, but NA secretion in ASRF-0.1 group could not be obtained significant result compared with control group. MHPG-SO4 (3-Methoxy-4-hydroxy-phenylethy leneglycol sulfate) levels in the brain resulted in a marked decreases of 16.5% and 18.9% respectively in ASRF-0.1 and ASRF-0.5 groups. NA/MHPG-SO4 ratios in the brain of ASRF-0.1 and ASRF-0.5 groups resulted in a significantly increase of 16.5% and 67.0%, respectively, compared with control group. These results suggest that anti-stress rose fruit (ASRF) drink also can effectively ridded the sociopsychological stress.

The effects of anti-stress chrysanthemum flower (ASCF) extract drink (ASCF-0.1% and ASCF-0.5% concentrations) were tested for the anti-stress action. ICR male mice (20$\pm$2 g) were fed with basic experimental diets and given free access to water containing these ingredients for 18 days. Psychological stress/sociopsychologcal stress exposed by foot-shock for 1 hour for 3 days. Both ASCF-0.1 and ASCF-0.5 groups in the sociopsychological stress resulted in a significant decrease of 28.1% and 27.3% in plasma corticosterone (CS) secretion compared with psychological stress (control group). Noradrenaline (NA) secretions in the brain were significantly increased 49.7% and 53.9%, respectively, in ASCF-0.1 and ASCF-0.5 groups compared with control group. MHPG-SO4 (3-Methoxy-4-hydroxyphenylethy-leneglycol sulfate) levels in the brain resulted in a marked decreases of 12.9% and 16.6%, respectively in ASCF-0.1 and ASCF-0.5 groups. NA/MHPG-SO4 ratios in the brain of ASCF-0.1 and ASCF-0.5 groups resulted in a significantly increase of 71.3% and 81.0%, respectively, compared with control group. These results suggest that anti-stress chrysanthemum flower (ASCF) drink can effectively ridded the sociopsychological stress.

This study was designed to investigate the effects of sea tangle (Laminaria japonica) extract (Dasi-Ex group: dry base 4.0%) and fucoidan-added (Fuco-I, II, III group: fucoidan of 1.0%, 2.0%, 3.0% added to Dasi-Ex) beverages on the anti-stress action. ICR male mice (20$\pm$2g) were fed basic experimental diets and given free through water bottle filled with these beverages instead of water for 18 days including sociopsychological stress. Body weight gains were consistently lower in Dasi-Ex and Fuco-I,II,III groups compared with control group, expecting in a inhibitory effect of obesity. Dasi-Ex group resulted in a significant decrease of 25% in serum corticosterone (CS) secretion, while Fuco-I,IIand IIIgroups resulted in a marked decreases of 45~55% in serum CS secretion compared with control group. Noradrenaline (NA) secretions were significantly increased about 15% in Dasi-Ex group, and 20~22% in Fuco-I,II,III groups compared with control group. Significant differences in brain MHPG-SO4 levels of Dasi-Ex group could not be obtained, but Fuco-I,II,III groups resulted in a marked decreases of 20~25% in brain MHPG-SO4 ratio of brain, but Fuco-I,II and III groups resulted in a marked increases of 45~60% in NA/MHPG-SO4 ratio of brain compared with control group. These results suggest that fucoidan beverage may play a effective role in a ridding of the sociopsychological stress by pivotal anti-stress effect of fucoidan.

장미(Rosa multiflora) 열매 추출물 1.0%, 3.0% 및 5.0%를 주재로 하여 개발한 기능성 스트레스 해소 요구르트 음료(RFEY-1.0, RFEY-3.0, RFEY-5.0 groups)로써 동물실험으로서 Communication box를 사용하여 사회ㆍ심리적 스트레스를 유발한 다음, 스트레스의 지표물질로서 혈액중의 코르티코스테론(CS)의 분비량 및 뇌조직의 노르아드레날린(NA)의 분비량과 대사산물로서 MHPG-SO$_4$의 생성량 및 NA/MHPG-SO$_4$ ratio를 분석하여 장미 열매 추출물을 주재로 한 항스트레스 요구르트 음료의 항스트레스효과(anti-stress effect)를 평가하였다. 스트레스 자극에 의해 증가하는 것으로 혈액 중에 분비되는 CS의 분비량은 RFEY-1.0, RFEY-3.0, RFEY-5.0의 투여그룹에서는 대조그룹 대비 각각 11.7%, 16.0%, 24.7%의 CS의 분비량이 유의적으로 감소하였다. 또한 스트레스 자극에 의하여 뇌조직에서 분비되는 NA의 분비량을 비교하여 보면 장미 요구르트 음료 RFEY-1.0, RFEY-3.0, RFEY-5.0의 투여그룹에서는 대조그룹 대비 각각 15.6%, 25.0%, 40.8%나 유의적으로 증가하였다. 뇌조직에서 NA의 대사산물로서 스트레스 자극에 의하여 증가되는 것으로 알려진 MHPG-SO$_4$의 생성량은 대조그룹 대비 각각 17.0%, 25.3%, 28.4%나 유의적으로 감소하였다. 또한 스트레스 자극에 의하여 감소되기 때문에 스트레스 지표(stress index)로서 널리 사용되고 있는 NA/MHPG-SO$_4$ ratio도 대조그룹 대비 RFEY-1.0, RFEY-3.0, RFEY-5.0의 투여그룹은 각각 39.5%, 67.3% 및 96.3%의 유의적인 증가효과가 인정되었다. 이상의 실험 결과를 종합해 볼 때 장미열매 추출물을 주재로 한 장미 요구르트의 항스트레스작용은 매우 효과적일 것으로 기대된다.
