Objectives : This study was conducted to confirm the skin anti-aging effect of Chungpyesagan-tang(CPSGT) extract. Methods : We performed MMT assay to confirm the cytotoxicity of CPSGT. After inducing matrix metalloproteinase-1(MMP-1) with tumor necrosis factor-α(TNF-α), we investigated mRNA expression and protein secretion of MMP-1 by real-time RT-PCR and ELISA. In addition, we measured the protein expression of mitogen-activated protein kinases(MAPKs) and transcription factors by western blot. Results : CPSGT was not cytotoxic at 25-800㎍/㎖. The mRNA expression and protein secretion of MMP-1 decreased when treated with CPSGT. The protein expression of p-ERK, p-JNK, p-p38 was decreased by CPSGT. In addition, the protein expression of p-c-jun and p-NF-κB, which are transcription factors, were also decreased. Conclusion : This suggests that CPSGT can inhibit MMP-1 and thus be a potential anti-aging substance.

The objectives of this study were to evaluate the anti-aging effects and investigate the effect of simulated gastrointestinal (GI) digestion on the anti-aging properties and intestinal permeation of the potential fish collagen hydrolysates (FCH). Therefore, procollagen synthesis, matrix metalloproteinase-1 (MMP-1) production, and Caco-2 cell permeability were analyzed before and after in vitro digestion for FCHs, low-molecular weight fractions (<1 kDa), and high molecular weight fractions (>1 kDa). After being subjected to GI digestion, the level of MMP-1 inhibition was maintained, although the procollagen production was significantly (>20%) lower with all samples. Also, the digested FCHs and their <1 kDa fraction yielded 9.1 and 13.8% increased peptide transport, respectively, compared to undigested samples. Based on the effective intestinal permeation and high digestive enzyme stability, the <1 kDa fraction of FCHs is a potential bioactive material suitable for anti-aging applications in the food and cosmetics industries.

Buckwheat (Fagopyrum esculentum) has been known for having strong anti-oxidant, anti-mutagenic, and anti-carcinogenic activities. The free radical theory of aging, also known as the oxidative stress theory of aging, claims that cellular oxidative damage accumulated with time is a major causal factor of aging. In the present study, we investigated the effect of buckwheat extracts on resistance to oxidative stress and aging using Caenorhabditis elegans as a model system. Survival under an oxidative-stress condition induced by paraquat increased markedly following 500mg/L buckwheat extracts treatment, suggesting lower cellular oxidative damage by buckwheat extracts. A lifespan assay also revealed that treatment of buckwheat extracts significantly extended both the mean and maximum lifespan in C. elegans. Interestingly, this lifespan-extension by buckwheat extracts was not accompanied by reduced fertility. These findings suggest that buckwheat extracts can confer longevity phenotype to C. elegans through its strong anti-oxidant activity and support the aging theory which emphasizes a pivotal role of oxidative stress during aging.

Objectives : We investigated the anti-aging effect on skin with the extract of the needles of red pine, Pinus densiflora. Methods : We measured various effects related to skin such as the anti-oxidant effect, the protection against ultraviolet (UV) irradiation, the inhibition of reactive oxygen species (ROS) generation, the induction of heat shock protein 70 (HSP70), the reduction of matrix metalloproteinase-2 (MMP-2) synthesis and senescent cell. Results : The results were as follows : The extract of the needles of red pine (RP) had the potent anti-oxidant effect and the ROS scavenging effect. Also RP preserved the systemic anti-oxidant enzyme system (superoxide dismutase and catalase) from UVB irradiation. RP protected the cell membrane from the damages induced by UVB irradiation. RP induced HSP70, a mediator of resistance to UVB irradiation. RP reduced the synthesis of MMP-2 induced by UVB irradiation. And RP inhibited the amount of senescent-associated (SA) ${\beta}-galactosidase$ staining, as a marker of replicative senescence. Conclusions : The results of our study indicate that the extract of the needles of red pine, Pinus densiflora, has anti-aging effects on skin.

본 연구에서는 화장품 신소재 개발을 위하여 맨드라미(Celosia cristata L.) 식물의 에탄올 추출물을 이용하여 생리활성 효과 정도 및 화장품의 응용에 대한 연구를 하였다. 맨드라미는 자생력이 강하고 전국 어디서나 재배가 용이한 장점을 가지고 있으나 세포수준이나 in vivo에서 맨드라미의 항산화 및 항노화 효과에 대한 실험 결과는 보고된 바 없다. 맨드라미 추출물의 피부 자극성을 알아보기 위해 세포 독성을 관찰하였으며 맨드라미 에탄올 추출물 $100{\mu}g/m{\ell}$에서 89.5%의 비교적 낮은 세포 독성을 나타내어 사람 섬유아세포에서의 세포활성 효과가 우수하였다. DPPH를 이용한 항산화 작용측정에 있어서 맨드라미 에탄올 추출물은 농도 의존적으로 항산화 작용을 나타내었고, $100{\mu}g/m{\ell}$에서 25%의 항산화력을 보였으며, silica에 의한 RAW 264.7 세포내 superoxide anion 생성을 최고 농도인 $100{\mu}g/m{\ell}$에서 49.5%로 억제하여 강한 항산화력을 나타냈으며, DCF-DA를 이용한 세포내 $H_2O_2$ 생성을 측정한 실험에서에서도 맨드라미 에탄올 추출물은 농도 의존적으로 항산화 작용을 나타내어 $100{\mu}g/m{\ell}$에서 73%로 강력하게 항산화력을 보였다. 또한 hydroxyl radical 생성을 모두 농도 의존적으로 억제하여 $100{\mu}g/m{\ell}$에서 69.7%의 강력한 억제력을 나타내어 항산화 효능이 매우 우수하다고 보여진다. 항노화 효능에 있어서 hyaluronidase 억제 결과 농도 의존적으로 효과가 우수하여 최고 농도인 $100{\mu}g/m{\ell}$에서 40%의 높은 억제율을 보였으며, 그 외 elastase에서는 39.7%의 억제율을 나타냈다. 이는 맨드라미가 hyaluronidase나 elastase발현의 전사단계에 관련하거나 혹은 단백질 번역 후 변형 (post-translation modification) 단계에 관여하여 효소를 억제하는 효과를 나타내는 것으로 추정해 볼 수 있다. 결론적으로 자원의 재생산이 용이한 맨드라미의 식용 및 약용 자원으로서의 활용가능성을 시사하며, 맨드라미 추출물을 제조하여 화장품에 응용하면 우수한 보습제 및 항산화제, 노화 방지 화장품을 개발할 수 있다고 판단되어진다.

Objectives : We compared the inhibitory effects of herb-combined remedies, which were recorded on "Yooam" prescription of Dongeuibogam, on cell migration and invasion, two critical cellular processes that are often deregulated during metastasis, in B16F10 melanoma cells. For this purpose, water extracts of Sipyukmiryukieum (SYMRKU), Danjacheongpitang (DJCPT), Cheongganhaeultang (CGHUT) and Jipaesan (JPS) were used. Methods : Cytotoxicity was assessed by an MTT assay. Wound healing and matrigel transwell assays were used to examine on B16F10 cell migration and invasion. The levels of mRNA and protein expression of matrix metalloproteinases (MMPs) and tissue inhibitor of metalloproteinases (TIMPs) were analyzed by RT-PCR and Western blotting. Results : Our data showed that DJCPT showed the strongest inhibitory effect among the four prescriptions in inhibiting cell motility of B16F10 melanoma cells within the concentration range that was not cytotoxic. The inhibitory potential of colony formation was higher in DJCPT and SYMRKU compared to the other two types of prescriptions, and the inhibitory effect of invasiveness is shown in order of DJCPT, SYMRKU, CGHUT and JPS. DJCPT, and SYMRKU strongly inhibited the activity and expression of MMP-2 and MMP-9, which are important mediators in cancer invasion, compared to CGHUT and JPS, and the increased expression of TIMP-1 and TIMP-2 was also more effective in these two prescriptions. In conclusion, DJCPT is expected to exhibit the most potent blocking effect on migration and invasion among four herb-combined remedies compared in B16F10 melanoma cells. Conclusion : Overall, the results of this study will be used as an important source to validate these prescriptions in animal models and to understand the mechanism of action of herbal remedies recorded in Dongeuibogam.
