Objectives : Biological activities of marine resources have been rarely evaluated compared with other herbal medicines. In the present study, we aimed to evaluate antimicrobial activities of aqueous and ethanolic extracts of five marine resources(Porphyra tenera, Laminariae Thallus, Sargassum, Ostreae Concha, Maliotidis Concha) against Propionibacterium acnes. Methods : Aqueous axtracts of five marine resources were prepared by decocting in tenfold tap water for 3 h. Etanolic extracts were obtained by extracting five marine resources with tenfold ethanol for 72 h at room temperature. The zone of growth inhibition and minimum inhibitory concentration (MIC) were determined against P. acnes after incubation for 48 h under anaerobic condition. Results : Ethanolic extracts of Porphyra tenera exhibited potent antimicrobial effects(MIC $62.5\;{\mu}g/m{\ell}$ against KCTC3320, MIC $31.25\;{\mu}g/m{\ell}$ against KCTC5527). However, all aqueous extracts tested had no effects on the growth inhibition of P. acnes. In addition, four ethanolic extracts except Porphyra tenera showed little inhibitory effect. Conclusions : These results indicate that ethanolic extracts of Porphyra tenera has antimicrobial activities against P. acnes and also warrant further development of Porphyra tenera extracts as a natural anti-acne agent.

To develope Hanbang beef jerky as health food, six kinds of beef jerky were prepared by adding sugar (A), licorice (B) and three kinds of spice extracts (clove: C, fennel fruit: D and Chungyang green pepper extract: E) and mixture of all extracts (F). The effects of the drying method and added spice extracts on the quality characteristics of the beef jerky were evaluated. In general, the air-blast dried beef jerky contained $31{\sim}33%$ moisture, $50.0{\sim}51.2%$ crude protein, $7.2{\sim}7.8%$ crude lipid and $3.0{\sim}3.3%$ crude ash. For the mineral content of the air-blast dried jerky, the most prevalent mineral was Na $(1540.08{\sim}1838.17$ mg%), followed by K, P, Mg, and Ca. The Ca content of the beef jerky was highest in the mixed extract group (88.53 mg%), and the lowest content was in sugar-added group (53.12 mg%). For the color properties, the L-value (lightness), a-value (redness) and b-value (yellowness) were higher in the air-blast dried beef jerky than in the hot air dried samples. The drying methods showed their greatest affect on the redness (a) for all six jerkies (p<0.001). For the preference by sensory evaluation, the beef jerky samples with added sugar (A) and licorice extract (B) had significantly higher scores than the beef jerky samples with the added spice extracts, for both of air-blast drying and hot air drying (p<0.05). Preference for the air-blast dried beef jerkies with added clove (C) and fennel fruits (D) were significantly higher, in terms of taste, color, softness and aftertaste as compared to the respective hot air dried jerkies (p<0.01). Considering all the obtained results, we concluded that licorice and spice extracts can be used as natural preservatives in the development of health foods and the air-blast drying method is recommended to improve the quality characteristics of beef jerky.

The purpose of this study was to investigate the possibility of herbal medicine complex extract (NI-01), which were prepared from 6 natural materials (Cinnamomum cassia Blume, Lonicerae Flos, Paeonia suffruticosa Andrews, Arctium lappa Linne, Schzandra chinesis Bailon, Elsholtzia ciliata Hylander), as a functional material for inhibition of atopic dermatitis. anti-oxidative activity was confirmed by measuring DPPH electron donating ability and ABTS+ radical scavenging ability. Cytotoxicity and NO inhibition were measured using RAW 264.7 cells to confirm anti-inflammatory efficacy. The test substance was orally administered to the pruritus-induced ICR mice to confirm the inhibition of pruritus. The bovine cornea opacity and permeability (BCOP) assay was performed to confirm safety for irritation. NI-01 showed high antioxidant activity in DPPH and ABTS+ methods. In the anti-inflammatory effect tests with RAW 264.7 cells, NO production was inhibited at NI-01 concentrations of 50 (14.9%) and 100 (4.2%) ㎍/mL, which indicated that the anti-inflammatory effect was increased in a concentration-dependent manner. NI-01 also showed anti-itching effect after inducing of itching by compound 48/80 in ICR mice. NI-01 was proved to be a non-irritant substance in BCOP assay. The results of this study suggested that the herbal medicine combined extract (NI-01) has high antioxidant, anti-inflammatory and anti-itching effects, and safety for irritation. Therefore, herbal medicine complex extract (NI-01) is thought to be highly applicable for the inhibitory ingredients of the atopic dermatitis.

This study was carried out to evaluate cytotoxic effects of Salvia miltiorrhiza extracts on NIH 3T3 fibroblasts and KB cell lines. Disruptions in cell organelles were determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The comparison of $IC_{50}$ of values of Salvia miltiorrhiza extracts in KB cell lines showed that their susceptibility to these extracts decreased in the following order: hexane extract > chloroform extract > methanol extract> dichloromethane extract > ethyl acetate extract>ethanol extract by the MTT method. The dried roots of Salvia miltiorrhiza was extracted several solvents, and then antimicrobial activity was investigated. The minimal inhibitory concentrations (MIC's) of the extract against microorganisms were also examined. Amtimicrobial activity of ketoconazol as reference was compared to those of extracts of hexane, chloroform, dichloromethane, ethyl acetate, ethanol and methanol. The antimicrobial activity of all extracts from the sample had growth inhibition activity against gram-negative bacteria, gram-positive bacteria and fungi. These results suggest that the hexane and chloroform soluble extracts of Salvia miltiorrhiza may be a valuable choice for the studies on the tumor cell lines and growth inhibition activity.

So-Hap-Hyang-Won, a traditional oriental medicine used in the treatment of stroke patients, was examined for its ability to reverse the cell damage caused by lipid peroxidation products and oxidative stress in bovine aortic endothelial cells (BAEC). The effects of herbal medicine on cell proliferation and recovery of oxidative damaged situation were studied in BAEC, which was considered an appropriate in vitro model for stroke resulting from various vascular diseases prevalent in advanced age. In a clinical study of stroke patients, So-Hap-Hyang-Won appeared to improve considerably arm and leg movements as well as consciousness disturbance condition, compared with other traditional medicines used for stroke. When BAEC were treated with extracts of the lyophilized herbal medicines, only that of So-Hap-Hyang-Won stimulated cell proliferation and showed no toxicity even at high concentrations. In studies of BAEC treated with extracts of the lyophilized material of the 14 components of So-Hap-Hyang-Won, only the extract of Foeniculi Fructus stimulated cell growth at all concentrations tested. Moreover, when cells were treated with Foeniculi Fructus (10 and 100 mg/ml) extract after prior exposure to t-BHP ($l0\mu\textrm{M}$) or HNE ($0.2\mu\textrm{M}$), lipid peroxidation products which are known to be involved in aging and vascular diseases, or after the exposure to SIN-l ($500\mu\textrm{M}$), which generates nitric oxide (NO) and other reactive oxygen species, there was substantial recovery from the oxidative damage, presumably due to the radical-scavenging effect of Foeniculi Fructus extract. Foeniculi Fructus not only showed stimulatory effects on cell growth and cell damage repair in BAEC, but also appeared to show the most anti-aging activity among all the herbal components of So-Hap-Hyang-Won.
