In vitro anti-obesity effects of anti-cancer (AC) functional kimchi in differentiated 3T3-L1 adipocytes were studied. We constructed three experimental groups: Control, standardized kimchi (SK), and AC functional kimchi (A-FK) that included active ingredients and Lactobacillus plantarum. Kimchi extracts did not show any cytotoxicity in pre-adipocytes in the concentration range of 1 - 5 mg/mL. A-FK significantly reduced fat droplet formation and absorbance in differentiated 3T3-L1 adipocytes, as shown by Oil red O staining, compared to Control and SK (P < 0.05). SK and A-FK reduced adipo-/lipogenesis related genes such as $C/EBP{\alpha}$, SREBP-1, LPL, and $LXR{\alpha}$ compared to Control (P < 0.05). Especially, A-FK more greatly reduced SREBP-1 and LPL compared to SK (P < 0.05). A-FK up-regulated the ${\beta}$-oxidation related gene CPT-1c and down-regulated the pro-inflammatory cytokine IL-6 compared to Control (P < 0.05). Based on the results, A-FK exhibited anti-obesity effects by inhibiting fat droplet formation and adipo-/lipogenesis related genes by regulating the ${\beta}$-oxidation related gene CPT-1c and pro-inflammatory cytokine IL-6. In previous studies, A-FK kimchi already exhibited a strong anti-cancer effect. These results indicate that A-FK increased anti-obesity activity in this model system due to its functional ingredients and anti-cancer functionality.

본 연구에서는 탁리산 열수추출물을 용매 분획하여 항산화, 주름억제, 미백효과에 대한 활성을 검증하여 화장품 소재로서 이용가능성을 연구하였다. 용매 분획물로 DPPH radical scavenge, ABTS radical scavenge, elastase, tyrosinase 저해활성을 확인하였고 에틸아세테이트 분획물(TW-EA)이 가장 높은 저해활성을 나타내었다. 세포내에서의 주름억제, 미백효과를 확인하기 위해서 western blot을 실시하였고 비교 검증을 위해 사용한 positive contol보다 TW-EA의 억제효과가 뛰어난 것을 확인하였다. 이러한 결과로 탁리산의 화장품소재로서 적용 가능성을 검증하였다.

식물성 식품재료를 대상으로 보체 용혈분석법$(TCH_{50})$ 을 이용하여 보체 활성화능(항보체 활성)에 대한 검색을 실시하였다. 총 38종의 식용 식물추출물 중 5종의 시료에서 대조구에 비해 60% 이상의 $TCH_{50}$ 감소를 일으키는 비교적 높은 활성을 나타냈으며 그 활성의 순서는 $1000{\mu}g/ml$ 시료 농도에서 생강>토란대>냉이>은행잎>달래이었다. 한편 가장 높은 활성을 보였던 생강에서 조제된 ZR-1의 경우 pronase 소화 후에는 활성의 변화가 없는 반면에 과요오드산 산화에 의해서는 급격한 활성의 감소를 나타냄으로써 ZR-1의 단백질 부위가 아닌 다당 부위가 활성에 기여함을 알 수 있었다. 또한 ZR-1의 항보체 활성은 $Ca^{2+}$ 이온 부재시 부분적인 감소현상을 보였으며, ZR-1을 정상인의 혈청과 반응 후 anti-humanC3를 이용하여 2차원 면역 전기영동을 행한 결과 C3의 분해산물을 관찰할 수 있었다. 또한 이들 획분은 $ACH_{50}$의 저해를 일으켰다. 동 결과로부터 ZR-1의 보체 활성화 양식은 classical pathway 뿐만 아니라 alternative pathway도 경유함을 알 수 있었다.

In order to examine the functionality of broccoli sprout (Brassica oleracea, BS), solvent extracts were prepared and their anti-oxidative and immunomodulating activities were compared with those of broccoli (B). EtOH extracts (E) were potently higher than hot-water extracts (HW) in the antioxidant contents and radical scavenging activity. In particular, the total polyphenolic contents in addition to ABTS and DPPH radical scavenging activity were significantly higher in EtOH extract of broccoli sprout (BS-E; 9.15 mg GAE/g, 4.52 mg AEAC/g, and 1.14 mg AEAC/g) compared with that of broccoli (B-E; 7.83 mg GAE/g, 3.63 mg AEAC/g, and 0.97 mg/AEAC/g). Whereas, total flavonoid content was significantly higher in B-E (1.60 mg QE/g) than BS-E (1.43 mg QE/g). Anti-inflammatory activity was investigated using LPS-induced cell line model at a concentration of $10{\sim}100{\mu}g/mL$, in which all solvent extracts of both broccoli sprouts and broccoli were not toxic to RAW 264.7 cell lines. In anti-inflammatory activity of broccoli sprouts, EtOH extracts also showed significantly more potent activity than hot-water extracts in all sample concentrations tested. In addition, BS-E ($100{\mu}g/mL$) inhibited nitric oxide (NO) and IL-6 production to 60.9% and 68.9% compared with the LPS inflammation group (without extracts), whereas B-E inhibited 49.6% and 54.9%. On the other hand, in immunostimulating activity by splenocytes and macrophages, hot-water extract showed significantly higher activity than EtOH extract. Especially, BS-HW stimulated the splenocyte proliferation (1.2-fold against saline group) and IFN-${\gamma}$ production (264.39 pg/mL) at $100{\mu}g/mL$, and the production of IL-6 (1.33-fold), IL-12 (1.09-fold) and TNF-${\alpha}$ (1.49-fold) from macrophages was also significantly enhanced over broccoli. In conclusion, broccoli sprouts showed more potent anti-oxidative, anti-inflammatory and immunostimulating activity than broccoli, suggesting the possibility of using broccoli sprouts as functional food materials.

Vinegar has been widely produced for a variety of industrial and domestic use as well as medicinal use. For sale of the commercial vinegar with herbal extracts, we produced an experimental black vinegar through sequential fermentation of alcohol, followed by acetic acid according to the manufacturer's procedure. To investigate the effect of anti-obesity of black vinegar on biochemical values, we evaluated enzyme activities via acetyl-CoA carboxylase (ACC), which plays a critical role in the lipid metabolism. We found that increased phosphorylated adenosine monophosphate (AMP) activated protein kinase (AMPK) and ACC in L6 mouse muscle cells treated with the manufactured vinegar. Based on the results, supplementation of experimental herbal black vinegar inactivates ACC, enhancing the phosphorylation of AMPK. Thus, the lipid oxidation and inhibitory effect of fatty acid synthesis by the black vinegar expects to facilitate the anti-obesity activity.

This study aims to investigate the biological activities related to hair loss of short anti-oxidant peptides (DK peptides) $5{\alpha}$-reductase inhibition and anti-oxidation. The series of DK peptides were generated amphipathic helical properties using leucines, lysines and tryptophan residues. Cell viability and free radical scavenging activities were performed using 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyl-tetrazolium bromide (MTT) and 2, 2-diphenyl-1-picrylhydrazyl (DPPH) assay, respectively. The DK peptides were investigated for inhibitory activity against $5{\alpha}$-reductase. Antioxidant activities were determined by means of, 2, 2-diphenyl-1-picrylhydrazyl (DPPH) assays. All peptides could inhibit $5{\alpha}$-reductase in lipopolysaccharide-stimulated macrophage. In conclusion, DK peptides was suggested as the most attractive ingredients for improving hair loss, because of the high inhibitory against $5{\alpha}$-reductase inhibition.

Results : 1. DPPH scavenging activity was stronger in Aralia continentalis Root than in Angelica pubescens Root 2. Superoxide anion radical scavenging activity was similar between Aralia continentalis Root and Angelica pubescens Root 3. The linoleic acid peroxidation inhibition effect was stronger in Aralia continentalis Root than in Angelica pubescens Root. 4. The phenolic component was higher in Aralia continentalis Root than in Angelica pubescens Root. 5. Both Aralia continentalis Root and Angelica pubescens Root increased the concentration of GSH and decreased SOD activity in mice, in which oxidative stress was induced, and the effect was stronger in Aralia continentalis Root. 6. Aralia continentalis Root increased GSH peroxidase activity but Angelica pubescens Root did not have such an effect. 7. Neither Aralia continentalis Root nor Angelica pubescens Root had a significant effect on catalase, ADH and ALDH in mice, in which oxidative stress was induced. Conclusions : Aralia continentalis Root has a stronger anti-oxidant effect than Angelica pubescens Root. Thus, although Aralia continentalis Root is not an original plant recorded in botanical literature, it may be usable based on the data about its effects.
