  • This study was intended to evaluate the anti-atopic effect of Sargassum fulvellum water extract (SFWE). Atopic dermatitis (AD) was induced in BALB/c mice by spreading 2,4-dinitrochlorobenzene (DNCB) to the dorsal skin area. The production of IL-4 and total IgE of the SFWE treated group was significantly less than the DNCB only group. On the other hand, the production of the IFN-γ of SFWE treated group was greater than that of the DNCB only group. In addition, SFWE alleviated the AD symptoms when compared to the DNCB only group and reduced the epidermal thickness and the number of mast cells in histological analysis. In conclusion, these results suggest that the application of SFWE has an anti-atopic activity through the modulation of IL-4 and IFN-γ cytokines, and the total IgE in DNCB-induced BALB/c mice. Therefore, SFWE can be utilized with atopic disease therapies.

  • 단체 급식의 증가와 더불어 편의식품을 선호하는 소비 경향에 맞추어 최소가공한 과일의 갈변저해를 위한 저해제를 탐색하였다. 실험에 사용한 과일은 배와 감으로 각각 박피하여 속심을 제거한 후 배는 8조각으로 절단하고 감은 1~2cm 두께로 slice 하였다. 저해제는 1% ascorbic acid, citric acid, NaCl, MgCl$_2$, CaCl$_2$, oxalic acid, EDTA, raffinose, salicylic acit, sporix를 사용하였다. 또한 열수 추출한 오약, 계피, 황기, 당기, 건칡, 진피, 천궁, 감초 등도 저해제로 사용하였다. 최소가공한 과일은 저해제에 3분간 침지한 후 물기를 제거하고 tray에 포장하여 실온에서 저장하면서 colorimeter를 이용하여 갈변도의 변화를 측정하였다. 갈변 정도를 나타내는 $\Delta$E 는 시간의 경과에 따라 점차 감소하는 경향을 보였으나 배의 경우 변화 정도가 크지 않았다. NaCl, MgCl$_2$, CaCl$_2$를 처리한 배의 갈변 정도가 가장 적었다. cysteine을 처리한 구에서는 황화합물 냄새가 났다. 또한 oxalic acid를 처리한 구에서는 연화가 빠르게 일어났으며 저장 시간이 경과함에 따라 수분이 용출되었다. 한약재는 자체 색으로 인해 배의 색변화를 증가시켰으며 이취가 발생했다. 또한 저장 시간이 경과함에 따라 건조가 빠르게 일어나 관능적으로도 좋지 않은 결과를 나타냈다. 감에서는 CaCl$_2$, MgCl$_2$를 처리한 구에서 색의 변화가 가장 적었으며 cysteine은 색변화는 적었으나 배의 경우과 같이 이취가 발생하였다. 한약제는 계피와 진피를 처리한 감에서 색의 변화를 저해하는 효과를 보였다.를 처리하였을 경우 당귀, 천문동을 처리한 구에서 효과를 보였다. oxalic acid는 갈변저해에는 효과적이었으나 시간이 경과함에 따라 수분의 용출이 증가하였으며 물성의 변화도 컸다. 또한 ZnCl$_2$를 처리한 구에서는 이취 발생과 수분 용출이 컸으며 색의 변화도 컸다.내었다. 고온 단시간 처리구의 경우 저온 장시간 처리구와는 달리 저장 1일 후부터 그 농도가 다소 상승되었다가 다시 감소는 경향을 보였다. 한편 열처리하여 냉각시킨 직후 및 저장1주 후 사과의 pH, 산도, 당도, 경도, 과육의 갈변도 등을 조사하였던 바 대조구 및 처리구간에 일부 항목에 있어서는 약간의 차이를 나타내었다. 대치할 수 있을 것이라고 사료된다. 수분함량은 기계적 검사보다 관능검사와 더욱 높은 상관관계를 나타냈다.내었다. 항균활성이 우수한 생약재를 농도별로 활성을 조사한 결과, 물 추출물과 10% Ethanol 추출물 모두 낮은 농도에서도 우수한 항균활성을 나타내었다.취와 함께 점질성 갈변물질이 생성되었다. 이와 같은 결과로 볼 때, BAAG의 처리는 BAAC의 경우보다 가격은 저렴하면서도 항균력은 우수한 천연 항균복합제재로써 농산물 식품원료에 적용하여 선도유지 기간을 연장할 수 있는 효과를 기대할 수 있었다. 과일 등의 포장제로서 이용할 가능성을 확인하였다.로 [-wh] 겹의문사는 복수 의미를 지닐 수 없 다. 그러면 단수 의미는 어떻게 생성되는가\ulcorner 본 논문에서는 표면적 형태에도 불구하고 [-wh]의미의 겹의문사는 병렬적 관계의 합성어가 아니라 내부구조를 지니지 않은 단순한 단어(minimal $X^{0}$ elements)로 가정한다. 즉, [+wh] 의미의 겹의문사는 동일한 구성요 소를 지닌 병렬적 합성어([$[W1]_{XO-}$ $[W1]_{XO}$ ]

  • Many efforts are made to achieve satisfactory cosmetic and functional result in the repair of cleft lip. However, repair may be complicated in many cases by distortion of the vermilion border, obliteration of the normal contour of the philtrum, and eclabium in spite of many methods used in these days. To achieve better results in cleft lip repair, thorough understandings of the relationship between the surface morphology of the upper and lower lip and the underlying musculature is necessary but reports about this topic is rare. So, our studies were performed on the full-thickness upper lips containing both philtral ridge up to columelar base and lower lip, 4 post-mortem specimens of 2 females and 2 males aged from 16 to 42, using serial histological sections taken in the transverse and vertical planes under light microscopy. Thorough understanding of the anatomical relationships is established and on the basis of our findings, we can postulate some criteria to create a normal and natural philtrum in a patient with a cleft lip, it would be necessary to restore the normal deep muscle attachments and superficial dermal attachments of the orbicularis muscle, to close the lip without tension, to restore thickness of the philtral ridge, and to minimise nonelastic scar tissue.

  • UV irradiation causes a variety of biologic effects on the skin. These effects can be devided to acute reactuons and chronic reacxtions by duration of UV irradiation. Acute reactions are erythema reaction, pigment reactions and changes in epidermal thickness. Among them erythema reaction is most common and conspicuous acute effects of the skin. Upon exposure to sun or artificial UV soures, a faint redness response of skin may begin. Larger exposure causes sunburn reaction which is exaggerated erythema reactionassociated with pain, swelling, vesicle and dulla. Extent and time course of erythema reaction depend upon several factors including wavelength and dose of UVR, skin conditions likeas skin type, site, color, temperature, humidity and environmental factors. Evaluation of erythema erythema induced by UV irradiation is difficult to quantify. Degree of redness of skin are usually estimated by subjective visual evaluation. The lowest exposure dose required to protuce erythema is called minimal erythema dose (mod). Repeated exposures of UVR result in photaging skin. In this condition we can see wrinkling, skin atrophy, dilated blood vessels and keratoses. In sensitive persons photocarcinogenesis is can Be developed on exposed area of skin. Recently skin canser is increasing now in our country. An effective public education and photopreventive method must be developed.

  • This morphological study was carried out to investigate the healing effect of open and occlusive dressing on rabbit skin wounds. The male white rabbits were given incision wound measuring 1.0cm in length and excision wound measuring $1.0{\times}0.2cm$ respectively on backs. Five rabbits among their received sterilization with beta dine twice a day and kept wound open. Another group of rabbits received sterilization and occlusive dressing with application of 1% sulfadiazine ointment and covering of gauze. The rabbits were observed at 5, 10, and 15 days after dressing with light microscope. The results were as follows. Both incision and excision wounds received open and occlusive dressing respectively revealed formation of scab and regeneration of epidermal epithelial cells at wound margin. The superficial dermis showed infiltration of neutrophils, monocytes, and lymphocytes, fibroblastic proliferation, and edema. On 10 days after opera and occlusive dressing the scab had disappeared and regeneration of epidermal epithelium was completed. The capillaries and inflammatory cells were decreased in number. However, edema and fibroblastic proliferation were more pronounced. On 15 days after opera and occlusive dressing, there were keratinization of regenerated epidermal epithelium, loss of inflammatory infiltration, edema, and capillary proliferation, and increase of fibroblastic proliferation and collagen fibers. The amounts of scars were less in incision wound than of excision one. There were no differences in healing processes between both dressing methods. According to the above results, it was conceived that sterilization of wound is more important in wound healing than dressing method in trivial wounds.

  • The purpose of this study is to evaluate the anti-oxidant and anti-microbial activity of syringin isolated from Cortex Fraxini to investigate their potential for use as safe natural compounds. Purified syringin was dissolved in distilled water for each concentration and used in each experiment. Syringin showed higher 2,2-Diphenyl-1-picrylhydrazyl radical scavenging than butylated hydroxytoluene (BHT) at a concentration of 50 ㎍/ml. In 2,2'-Azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging, activity was similar to that of BHT at all concentrations. In antioxidant protection factor measurement, activity of syringin slightly increased as the concentration increased, as did the inhibitory effect of thiobarbutric acid reactive substances. In evaluating anti-microbial activity, the clear zones of Listeria monocytogenes KCTC 13064, Staphylococcus aureus KCTC 1916, Escherichia coli KCTC 2571, and Helicobacter pylori HPKCTC B0150 at a concentration of 200 ㎍/ml were found to be 17.8 mm, 20.45 mm, 17.05 mm, and 16.8 mm, respectively, but no clear zone was observed in the case of Candida albicans ATCC 10231. The activity against water-soluble antioxidants was therefore superior to that against lipid-soluble antioxidants. Anti-microbial activity was examined by inhibiting growth against gram-positive and -negative strains, and anti-fungal activity was not observed. Based on the results of this study, syringin has possible applications as a natural anti-oxidant and anti-microbial material.

  • In order to investigate the beneficial effects of parsely (Petroselinurn sativum) extract on skin, we measured the synthesis of total collagen and type I procollagen in cultured normal human fibroblast (NHF), the synthesis of prostaglandin E$_2$(PCE$_2$), interleukin 1 ${\alpha}$(IL -1 ${\alpha}$) and tumor necrosis factor ${\alpha}$ (TNF ${\alpha}$) in HaCaT cell and we also measured dermal thickness and density in hairless mouse (Female albino hairless mice, Skh:hr-1). As the results, the synthesis of total collagen and type I procollagen were increased 23% and 18% respectively, after 1 $\mu\textrm{g}$/mL parsley extract treatment. The producions of PGE$_2$ induced by UVB irradiation were decreased 60% after 1 $\mu\textrm{g}$/mL parsley extract treatment. The treatment with 1 $\mu\textrm{g}$/mL parsley extract also decreased the synthesis of IL -1 ${\alpha}$ and TNF ${\alpha}$ induced by 10 uM RA, 100 $\mu\textrm{g}$/mL SLS and 30 mJ/$\textrm{cm}^2$ UVB irradiation, After 4 days treatment with 1% parsley extract, the dermal thickness of hairless mouse was increased 1.5 times and the density of dermis was tighter than control. These results indicate that parsley extract have anti-aging and anti-irritation effects on skin.

  • The regeneration and differentiation of the cutaneous pigment system in the goldfish, Carassius auratus during the wound healing process were studied with high magnification electron microscope. The cutaneous pigment cells of the normal tissues were composed of three kinds of dermal chromatophores-xanthophores, leucoiphores and melanophores. While xanthophores contain two kinds of pigment granules-pterinosomes and carotenoid vesicles, leucophores and melanophores contain amorphous pigment granules (leucosomes) and oval shaped electron dense melanin pigment granules (melanosomes) respectively. After injury, primary wound healing responses being carried out by migration of epidermal cells and hemocytes spreading over the wound surface at the day of wounding. And at the time of primary wound closure, 5 to 7 days after wounding, rER rich cells-presumably common precursors of dermal chromatophores-immigrated into the wound area. First redifferentiated chromatophores appeared 3 weeks after wounding. Pigment granules of the chromatophores were emerged from the cytoplasmic Golgi complex via rough endoplasmic reticulum. Pinocytotic vesicles which associated with accumulation of pigment material, appeared only at the inner surface of the chromatophores adhering to the rER rich cells, characteristically. The differentiation of each chromatophore in addition to integumental wound repair were accomplished within 4 weeks after wounding at most cases, however the total numbers and densities of these repaired chromatophores still primitive state. Moreover, It has been revealed that complete repair of chromatophores at wounded tissues from burns requirs more than 3 months in normal environment.

  • The present study investigated the protective effects of Bifidobacterium bifidum culture supernatants (BbSC) and intracellular cell-free extracts (BbICFE) on human dermal fibroblasts (HDFs) against ultraviolet-B (UV-B) irradiation. HDFs were treated with UV-B, UV-B+BbCS, and UV-B+BbICFE. Treatment of UV-B-irradiated HDFs with BbCS and BbICFE significantly increased cell viability compared to UV-B-irradiated HDFs. BbCS treatment reduced senescence in HDFs by approximately 40.0%. Moreover, sub-G1 phase was significantly reduced in BbCS- and BbICFE-treated HDFs (3.3% and 4.5%, respectively). The effect of UV-B on oxidative damage of HDFs was measured by dichlorofluorescin diacetate. Fluorescence intensity significantly increased in UV-B-irradiated HDFs. Inhibition of cellular reactive oxygen species in HDFs treated with 0.01% BbCS was the highest at 34.1%. Levels of p21 and p53 protein expression induced by UV-B irradiation were reduced by treatment with BbCS and BbICFE (47.0% and 35.6%, respectively). These results show that BbCS and BbICFE reduce UV-B-induced cellular senescence and apoptosis in HDFs. Thus, BbCS and BbICFE can be used as potential agents for protection of UV-B-induced skin cell damage.
