Objects : The purpose of this study was to observe the effect of Salviae Miltriorrhiza Radix(SMR) water-extract on intracerebral hemorrhage(ICH) and neuronal apoptosis in the injured areas. Method : ICH was induced by the stereotaxic intrastriatal injection of bacterial collagenase type IV in Sprague-Dawley rats. The rats were givened oral SMR treatment once a day for three days after the ICH treatment. TUNEL positive cells in the affected regions were performed by TUNEL assay, Bax and Bcl-2 positive cells by immunohistochemistry and the Bax expression by western blotting method. Results : The results are as follow; 1. SMR significantly reduced the number of TUNEL positive cells in the peri-hematoma reigions of ICH-induced rats. 2. SMR significantly reduced the number of Bax positive cells in the peri-hematoma regions of ICH-induced rats. 3. SMR did not affect the number of Bcl-2 positive cells in the peri-hematoma regions of ICH-induced rats. 4. SMR significantly reduced the Bax expressions compared with ICH group in hemorrhagic hemisphere of ICH-induced rats. Conclusion : These results suggest that SMR is effective in reducing neuronal apoptosis.

The matrix metalloproteinases (MMPs) are members of a unique family of proteolytic enzymes that degrade components of the extracellular matrix. Significant evidence has accumulated to directly implicate members of the MMPs in tumor invasion and metastasis formation. To investigate the correlation between ras oncogene and MMP gene expression in various tumor cells, we detected mRNAs for the ras, MMP-2 and MMP-9 (72 kD and 92 kD type IV collagenases, respectively) genes in nine human tumor cell lines. The ras gene was expressed in seven cell lines; MMP-2 in three; MMP-9 in two cell lines tested. There was no direct correlation between the ras oncogene and MMP expression. A clear difference in the mRNA expression between MMP-2 and MMP-9 was observed among the cell lines. As an approach to study the effect of the ras oncogene on metastasis, we examined the expressions of MMP-2 and MMP-9 in HT1080 cells transfected with the v-H-ras gene. MMP-9 expression was Significantly enhanced in the ras-transfected HT1080 cells compared with the nontransfectants while ras transfection did not affect the expression of MMP-2. These results suggest the possible inducing effect of the ras oncogene on the metastasis by activation of the MMP-9 gene in HT1080.

Styela plicata are naturally-occurring marine resources easily found along the coastlines that have established their niche as functional food and nutraceuticals ingredient along with their increasing consumer demand. Ascidian contain a large amount of dietary fiber but only the meat has been utilized and consumed while the rest of its parts are discarded. Also, various studies have been conducted on the meat of ascidians while studies on the functionality of the ascidian tunics, which were mostly undervalued, were scarce. In this study, we investigated and explored the glycosaminoglycans (GAGs) contents in the tunics of S. plicata, and their potential use as functional ingredient in pharmaceutical and nutraceutical applications. Sulfated GAGs and uronic acids contents were 8.9-10.7 g/100 g and 9.4-11.3 g/100 g, respectively. Highest GAGs content was extracted with optimum Brix at 7-9. Extraction efficiency using hot water at 121℃ was 4.22% while enzyme extraction using Protamex was more efficient at 5.91%. GAGs extracted from S. plicata tunics exhibited collagenase inhibitory activity of 75.2% at 100 ㎍/mL and procollagen synthesis activity of 80.1% at 100 ㎍/mL.

The decreasing effect of wrinkle on the pressure sensitive adhesive hydrogel patches containing ulmi cortex extract and sorbitol as the drug for anti-wrinkle were investigated. In this study, hydrogels were prepared by the crosslinking reaction of acrylic polymers and aluminum ions produced by L(+)-tartaric acid hydrolysis of the dihydroxy aluminum aminoacetates. The inhibition concentration of ulmi cortex extract on the collagenase exhibited at 0.01%. Furthermore, the moisturizing effect of hydrogel patches formulated with sorbitol was higher than that without it. In vivo animal test in hairless mouse showed that the ulmi cortex-loaded hydrogel patches had about 31.2% of anti-wrinkle effect compared to blank (before attaching the patches). Human test showed that only 33% of subjects showed the decreasing of wrinkle during 8 weeks. In conclusion, the model pressure sensitive adhesive hydrogel patches in this study would be pharmaceutically applicable for the wrinkle treatment on the facial skin.

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.
