Objective : This study was performed to assess the effects of Aloe and Violae herba extracts on skin disease and skin beauty. Methods : Anti-oxidant effects were measured by the scavenging for DPPH radical, xanthine oxidase activity. Anti-inflammatory effects were examined by relations in NO synthesis, IL-$1{\beta}$, IL-6, TNF-$\alpha$, NF-kB, COX-2, MAP kinase. The skin wrinkle formation effects were measured by collagenase and elastase activities. The whitening effects were examined by tyrosinase activities, melanin synthesis in MNT-1 cell. Results : 1. In an anti-oxidant test, Aloe and Violae herba extracts showed high radical scavenging activity. 2. In an anti-inflammatory test, Aloe and Violae herba extracts strongly inhibited the lipopolysaccharide(LPS)-induced nitric oxide(NO) release from the RAW 246.7 macrophage cells. Aloe and Violae herba extracts also inhibited the LPS-induced IL-$1{\beta}$ and COX-2 expressions. The inhibitory effects of Aloe and Violae herba extracts on macrophage activation were via the inhibition of NF-kB, evidenced by transient transfection assay. Furthermore, Aloe and Violae herba extracts weakly inhibited the activation of Jun-N-terminal kinase(JNK) but they did not have any effects on p38 MAP kinase in RAW 264.7 cells. 3. In the skin wrinkle formation assay, Aloe extract strongly inhibited collagenase and elastase, whose activity are tightly related with the wrinkle formation. 4. In the skin whitening assay, Aloe and Viloae herba extracts weakly inhibited tyrosinase activity, however, it was not statistically significant.

Marine resources have various biological activities and their constituents are more novel than those of land organisms. Several biologically active constituents have been found in marine organisms. Recently, many studies have reported that marine animals (MAs) can be used as functional ingredients in functional foods or nutraceutical due to their health benefits. However, no studies have extensively investigated the cosmeceutical activities of MAs extracts. Here, 70% ethanol extracts of 38 MAs were investigated for their activities of whitening and anti-aging properties for use as materials in novel cosmeceuticals. Anti-aging activities were determined by skin aging-related enzyme activities (anti-collagenase, anti-elastase, anti-hyaluronidase) and whitening activities (anti-tyrosinase, anti-3,4-dihydroxyl-L-phenylalanine [DOPA] oxidation) evaluated by colorimetric method. Among the 38 MAs, we found that Urechis unicinctus and Petrosia corticata extracts showed the strongest inhibitory effects against tyrosinase and DOPA oxidation, respectively. Our results additionally showed that Protankyra bidentata extract might provide a major source of anti-hyaluronidase and anti-elastase; meanwhile, anti-collagenase effects were similar in most MAs. Overall, these results suggest that extracts of marine animals have potential as a tyrosinase, collagenase, elastase, and hyaluronidase inhibitors. Taken together, MA resources could be considered as a novel cosmeceutical agent to be applied in cosmetic industry.

NUC1 (Nutraceutical compound 1) is an ethanol extract composed of a formulation based on medicinal herbs traditionally used for the treatment of arthritis in Korea and China. This study investigated the therapeutic effects of NUC1 on osteoarthritis (OA). The protective effect of NUC1 on OA was tested in a rabbit model of collagenase-induced arthritis (CIA) for 4 weeks. Results were compared among four groups (n = 9 per group): the normal group (untreated), the CIA group (vehicle control), the NUC1 group (CIA rabbits treated with 200 mg/kg NUC1), and the JOINS group (positive control, CIA rabbits treated with 200 mg/kg JOINS tablet). NUC1 significantly inhibited NO production (p < 0.05 at 125 ㎍/ml, p < 0.01 at 250 ㎍/ml, and p < 0.001 at 500 ㎍/ml) and iNOS expression in macrophages, in a concentration-dependent manner. NUC1 also inhibited the release and protein expression of MMP-1, 3, and 13, in TNF-α-induced chondrosarcoma cells in a concentration-dependent manner. In vivo, the MMP-1 and MMP-3 levels in synovial fluids were significantly (p < 0.05) lower in NUC1 group (77.50 ± 20.56 and 22.50 ± 7.39 pg/ml, respectively) than in the CIA group (148.33 ± 68.58 and 77.50 ± 20.46 pg/ml, respectively). Also, in histopathological, NUC1 ameliorated articular cartilage damage in OA by increasing the abundance of chondrocytes and proteoglycan in the articular cartilage. Thus, NUC1 showed promise as a potential therapeutic agent, and it can be generalized to a broader study population in different OA animal models.
