This study focused on the preparation and characterization of anti-wrinkle peptides from the salted and fermented shrimp (Acetes japonicus) inoculated with Salinivibrio cibaria BAO-01 (SFSC). The results showed the proximate composition of SFSC to be 9.23% water, 75.32% protein, 0.23% fat, and 13.3 mg/g ash. Interestingly, the S. cibaria fermentation significantly increased the amount of methionine, leucine, and arginine. The in vitro antioxidant activity was assayed by the diphenylpicrylhydrazyl method and its IC₅₀ value was found to be 43.02±2.84 ㎍/mL. It was observed to inhibit the activity of elastase, tyrosinase, collagenase, and hyaluronidase. The IC₅₀ values of SFSC were 182.75±12.38 ㎍/mL for anti-elastase activity, 186.78±7.95 ㎍/mL for anti-tyrosinase activity, 444.4±34.81 ㎍/mL for anti-collagenase activity, and 1447.95±28.92 ㎍/mL for anti-hyaluronidase activity. These results suggest that salted and fermented shrimp has strong potential for the development of nutricosmetic products.

Anti-melanogenesis and skin anti-wrinkle effects of methanol (ME) and hot water (HE) extracts from the fruiting bodies of Ganoderma applanatum were investigated in this study. The total phenolic contents of the ME and HE of the mushroom were 11.68 and 3.15 ㎍ GAEs/mg, respectively, whereas the total flavonoid contents of the ME and HE were 21.82 and 2.69 ㎍ QEs/mg, respectively. The survival rate of B16-F10 murine melanoma cells treated with 750 ㎍ ME and HE were 83.46% and 85.54%, respectively, thereby suggesting that mushroom extracts were slightly cytotoxic at the tested concentration. The in vitro tyrosinase inhibition by ME (83.15%) and HE (83.44%) was significantly lower than that of kojic acid (99.61%), the positive control, at 2.0 mg/mL. Although the inhibition of cellular melanin synthesis in B16-F10 melanoma cells by 2.0 mg/mL of ME (50.24%) and HE (51.24%) was lower than that of arbutin (64.84%), the inhibition by both ME and HE was higher than 50%. Collagenase inhibition by HE was comparable to 2.0 mg/mL epigallocatechin (EGCG), the positive control; however, elastase inhibition by ME and HE was lower than that of EGCG at the concentration tested. The results showed that the fruiting bodies of G. applanatum had good anti-tyrosinase, good anti-collagenase, and moderate anti-elastase activities, which might be useful for developing novel skin-whitening and anti-wrinkle agents.

The effect of cryopreservation on extracellular matrix was studied with the ultimate objective of permiting a prediction of the tendency of aorta conduit tissue to calcify following transplantation. Cryopreserved and fresh porcine aorta conduit tissues were extracted using guanidine-hydrochloride (Gdn-HCl) followed by sequential digestion of the tissues with collagenase, elastase, and papain. Glycosaminoglycans (GAGs) of the proteoglycans (PGs) were isolated and quantitated. Gdn-HCl extracted about 61% and 62% of the total GAG (proteoqlycan) material from cryopreserved and fresh tissues, respectively. Collagenasesolubilized proteoglycans from Gdn-HCl extracted tissue represented 20% and 13%, respectively, of the total GAGs present in cryopreserved and fresh tissues. Subsequent elastase hydrolysis of collagenase-digested tissue released about 11% of total GAGs from cryopreserved tissue and 16% from fresh tissue. The remaining 8%, from cryopreserved tissue, and 9%, from fresh tissue, of the total GAGs were obtained after using a papain hydrolysis. There was essentially no difference between fresh and cryopreserved tissues in the relative distribution of proteoglycans in the extracts and digestions except in the initial digestion step where more proteoglycans were obtained from collagenase solubilization of cryopreserved tissue than fresh tissue (p<0.05). The histologic status of the fresh and cryopreserved porcine aortic conduit did not differ markedly. The normal tissue architecture was not affected markedly by the cryopreservation procedure as neither alteration of elastic structure, fibrous proteins nor alteration of nuclear distribution or smooth muscle cell morphology was detected. Quantitative tissue mineral studies revealed that the mean calcium content of the cryopreserved aorta conduit tissue $(165{\pm}3\;{\mu}g/g\;wet\;tissue)$ was higher than that of the fresh tissue $(105{\pm}4\;{\mu}g/g\;wet\;tissue)$ $(p<0.05)$. The mean phosphorus content was $703{\pm}35\;{\mu}g$ wet tissue from cryopreserved tissue and $720{\pm}26\;{\mu}g$ wet tissue from fresh tissue. The study indicates that there is no significant alteration in the distribution of PGs in properly cryopreserved tissue, but the total calcium level appears to be increased in tissue cryopreserved by the cryopreservation process used in this study.

Background: The purpose of this study was to investigate whether Sibseonsan (SSS) is an effective antiinflammatory, anti-wrinkling, and whitening agent. Methods: To determine whether SSS had an anti-inflammatory effect, a murine macrophage cell line was used (RAW 264.7) and production of DPPH, NO, TNF-α, and PGE₂ were measured. To ascertain potential anti-wrinkle effects of SSS in these cells, collagenase and elastase production were measured. To verify whether SSS had a whitening effect, tyrosinase activity and DOPA staining were performed using a melanoma cell line (B16/F10). Results: There was no significant reduction in survival of SSS-treated RAW 264.7 cells, up to 400 ㎍/mL. Free radical scavenging (23.96 ± 1.85%) was observed in RAW 264.7 cells treated with SSS at a concentration of 400 ㎍/mL. The SSS treatment group (400 ㎍/mL) significantly inhibited NO production compared with the LPS stimulated treatment group. The SSS treatment of macrophage cells appeared to reduce production of TNF-α in a concentration dependent manner. There was a significant reduction in the concentration of PGE₂ by about 25% in the SSS treatment (400 ㎍/mL) group (p = 0.05). Compared with the control, the production of collagenase and elastase in B16/F10 cells treated with SSS (400 ㎍/mL) was greater by 26.37% and 45.71%, respectively. The SSS treatment (400 ㎍/mL) group showed a significant reduction by about 17% in tyrosinase production in B16/F10 cells. The SSS treatment group showed little change in DOPA staining. Conclusion: SSS extract may be useful for the treatment and prevention of inflammatory diseases and may have anti-wrinkle and whitening effects. These results may support the use of SSS in clinical practice.

Skin aging is a complex biological process due to intrinsic and extrinsic factors. Free radical oxidative is one of extrinsic factors that induce activation of collagenase, elastase and hyaluronidase. Natural product from plants has been used as antioxidant and antiaging. This study aimed to evaluate antioxidant and antiaging properties of Hibiscus sabdariffa extract (HSE) and its compounds including myricetin, ascorbic acid, and ${\beta}$ carotene. The phytochemical of H. sabdariffa was determined using modified Farnsworth method and presence of phenols, flavonoids and tannins were in moderate content, whereas triterpenoids and alkaloids were in low content. Total phenolic content performed using Folin-Ciocalteu method, was $23.85{\mu}gGAE/mg$. Quantitative analysis of myricetin, ${\beta}-carotene$, and ascorbic acid of HSE was performed with Ultra-High Performance Liquid Chromatography (UHPLC) that shows $78.23{\mu}g/mg$ myricetin, $0.034{\mu}g/mg$ ${\beta}-carotene$, whilst ascorbic acid was not detected. HSE has lower activity on DPPH ($IC_{50}=195.73{\mu}g/mL$) compared to ${\beta}-carotene$, the lowest in ABTS assay ($IC_{50}=74.58{\mu}g/mL$) and low activity in FRAP assay ($46.24{\mu}MFe(II)/{\mu}g\;$) compared to myricetin, ${\beta}-carotene$. Antiaging was measured through inhibitory activity of collagenase, elastase, and hyaluronidase. HSE had weakest collagenase inhibitory activity ($IC_{50}=750.33{\mu}g/mL$), elastase inhibitory activity ($103.83{\mu}g/mL$), hyaluronidase inhibitory activity ($IC_{50}=619.43{\mu}g/mL$) compared to myricetin, ${\beta}-carotene$, and ascorbic acid. HSE contain higher myricetin compared to ${\beta}-carotene$. HSE has moderate antioxidants and lowest antiaging activities. Myricetin is the most active both antioxidant and antiaging activities.
