The purpose of this study is to investigate whether the effects of topically applied petrolatum and glycerin on the barrier repair of acetone-induced skin damage in 6 beagle dogs. To confirm the effects of petrolatum and glycerin on acetone disrupted skin models, we performed to evaluate the characteristics of transepidermal water loss and SC hydration and scanning electron microscopic observations. TEWL and SC hydration measurements were carried out 3, 6, 12, 24, 48h after applying petrolatum and glycerin during recovery from acute disruption. Our results showed that there were some different effects between petrolatum and glycerin on the acetone damaged skin such as barrier function repair process and SC hydration status. The results indicate that the significant improvement could be observed in glycerin apply more than petrolatum after acetone damages, and further study will be required.

Ursolic acid (UA) and Oleanolic acid (ONA), known as urson, micromerol and malol, are pentacyclic triterpenoid compounds which naturally occur in a large number of vegetarian foods, medicinal herbs, and plants. They may occur in their free acid form or as aglycones for triterpenoid saponins, which are comprised of a triterpenoid aglycone, linked to one or more sugar moieties. Therefore UA and ONA are similar in pharmacological activity. Lately scientific research, which led to the identification of UA and ONA, revealed that several pharmacological effects, such as antitumor, hepato-protective, anti-inflammatory, anticarcinogenic, antimicrobial, and anti-hyperlipidemic could be attributed to UA and ONA. Here, we introduced the effect of UA and ONA on acutely barrier disrupted and normal hairless mouse skin. To evaluate the effects of UA and ONA on epidermal permeability barrier recovery, both flanks of 8-12 week-old hairless mice were topically treated with either 0.01-0.1mg/mL UA or 0.1-1mg/mL ONA after tape stripping, and TEWL (transepidermal water loss) was measured. The recovery rate increased in those UA or ONA treated groups (0.1mg/mL UA and 0.5mg/mL ONA) at 6h more than 20% compared to vehicle treated group (p < 0.05). Here, we introduced the effects of UA and ONA on acute barrier disruption and normal epidermal permeability barrier function. For verifying the effects of UA and ONA on normal epidermal barrier, hydration and TEWL were measured for 1 and 3 weeks after UA and ONA applications (2mg/mL per day). We also investigated the features of epidermis and dermis using electron microscopy (EM) and light microscopy (LM). Both samples increased hydration compared to vehicle group from 1 week without TEWL alteration (p < 0.005). EM examination using RuO4 and OsO4 fixation revealed that secretion and numbers of lamellar bodies and complete formation of lipid bilayers were most prominent (ONA=UA > vehicle). LM finding showed that thickness of stratum corneum (SC) was slightly increased and especially epidermal thickening and flattening was observed (UA > ONA > vehicle). We also observed that UA and ONA stimulate epidermal keratinocyte differentiation via PPAR Protein expression of involucrin, loricrin, and filaggrin increased at least 2 and 3 fold in HaCaT cells treated with either ONA (10${\mu}$M) or UA (10${\mu}$M) for 24 h respectively. This result suggested that the UA and ONA can improve epidermal permeability barrier function and induce the epidermal keratinocyte differentiation via PPAR Using Masson-trichrome and elastic fiber staining, we observed collagen thickening and elastic fiber elongation by UA and ONA treatments. In vitro results of collagen and elastin synthesis and elastase inhibitory activity measurements were also confirmed in vivo findings. These data suggested that the effects of UA and ONA related to not only epidermal permeability barrier functions but also dermal collagen and elastic fiber synthesis. Taken together, UA and ONA can be relevant candidates to improve epidermal and dermal functions and pertinent agents for cosmeseutical applications.
Hydroxyproline and Pro-Hyp dipeptide are the digestive products of collagen hydrolysate called collagen peptide. Some suggested that collagen peptides could improve aged or damaged skins, however, the effects of collagen peptides on the skin have not been known. In this study, we investigated the effects of digestive products of collagen peptides, hydroxyproline and Pro-Hyp dipeptide on skin quality using the UV-damaged dorsal skin of hairless mouse as a model system. Female SKH hairless mice were pre-irradiated with UV for 7 weeks, and then hydroxyproline, Pro-Hyp dipeptide were orally administered for 7 weeks with UV irradiation. Wrinkle formation (by replica image), skin elasticity, barrier status (by TEWL, transepidermal water loss), epidermis thickness, and biophysical changes in the stratum comeum (by hematoxylin & eosin staining) were examined. With the oral peptide treatment, effects such as skin barrier maintenance, anti-skin thickening, and recovery of the stratum corneum were observed. These results indicate that oral intake of collagen peptides may have beneficial effects on damaged skin cells.

Background and Objective : Increasing interest in anti-aging and anti-wrinkling agents for the skin has triggered the recent outflow of researches and studies in this field. This study was designed to investigate the effects of bee venom on skin wrinkling and skin aging by testing the skin wrinkling, skin elasticity, trans-epidermal water loss (TEWL), free radical level, anti-oxidative agent level, and skin tissue after infusion of bee venom on hairless mouse. Materials and Methods : Fifteen hairless mice aged between 36~40 weeks were divided randomly into 3 Group; the Bee Venom Syringe Group, the Bee Venom Needle Group, and the control group. The Bee Venom Syringe Group were injected subcutaneously with bee venom (0.1cc in total) using an insulin syringe on three spots in the lumbar spine (one spot on the center and two spots 1~2cm to the side bilaterally). The Bee Venom Needle Group were pricked with bee venom-smeared acupuncture needles on three longitudinal spots in the lumbar spine each 1cm apart, after which the needles were removed 10 minutes later. The Control Group did not receive any form of intervention. All procedures took place thrice a week for four weeks, during which the mice were allowed free access to water and fodder. The mice were measured and compared in the weight, skin wrinkling scale, skin elasticity, and TEWL before and after the experiment. After the experiment, blood samples were taken to measure the free radical and anti-oxidative agent level, and the skin tissue was sliced for examination. Data was analyzed using the SPSS program (ver 12.0). The ANOVA analysis was used to compare and contrast the three groups, and t-test for paired samples was used to evaluate skin-wrinkling before and after experiment. The cut-off p-value of significance was set at p<0.05. Results : 1. Administration of bee venom did not cause serious weight loss or gain. 2. Compared to the control group, the Bee Venom Syringe Group and the Bee Venom Needle Group both showed a decrease in skin wrinkling scale after intervention. Especially, the Bee Venom Syringe Group showed a significant decrease (p<0.05). 3. Compared to the control group, the Bee Venom Syringe Group and the Bee Venom Needle Group both showed an increase in skin elasticity. Especially, the Bee Venom Syringe Group showed a significant increase (p<0.05). 4. No significant change in TEWL was found in the mice in all the three groups before and after experiment. 5. Free radical level was normal in all 15 mice in all the three groups, and anti-oxidative agent was not significantly different across the three groups. 6. The Bee Venom Syringe Group, the Bee Venom Needle Group, and the control group did not show any significant difference in the thickness of epidermis and dermis, infiltration of inflammatory cells, and skin wrinkling. The epidermis layer was relatively better preserved in the Bee Venom Syringe Group as compared to the Bee Venom Needle Group and the control group. Conclusion : Direct injection of bee venom on the hairless mouse using a syringe was found to improve wrinkling of the skin and increase skin elasticity but did not show effectiveness on skin dryness due to water loss. The bee venom appears to have suppressive effects on skin wrinkling, one of the symptoms of skin aging, through a process independent of suppression of free radicals or increase of anti-oxidative agent.
The aims of the present study were to characterize the effect of glucocorticosteroids (GCs) on the normal canine skin and to evaluate the effect of a lipid mixture (LM), containing cholesterol, pseudoceramide, and free fatty acid, on the steroid-induced damaged skin of dogs. Five beagles were involved and the skin of the back of each dog was topically applied with four kinds of GCs twice daily for 28 days. LM was applied after that period of GCs application. Transepidermal water loss (TEWL), skin hydration, and skin pH were assessed during experimental periods and histopathological evaluation was performed. TEWL was significantly increased, with a maximum increase obtained on day 28 (p < 0.01). Skin pH was significantly decreased, with a maximum decrease obtained on day 28 (p < 0.01). Skin surface hydration was significantly increased on day 3, but values of skin hydration were progressively decreased and finally reached those of baseline. In histology, as results of steroid application, losses of keratin layers in the stratum corneum and edematous changes in the upper parts of dermis, and consequently, thickness of the epidermis and the stratum corneum were decreased. In addition, the numbers of hair follicles were markedly decreased in steroid control as compared to intact control. However, these skin atrophic changes were markedly inhibited by treatment of LM as compared with steroid control in the present study. Moreover, all biophysical parameters were reached to the baseline after LM treatment. These results showed that the topically applied GCs induced skin barrier impairment and a LM should be effective on repair of disturbed skin barrier function in dogs. Therefore, it is concluded that a LM tested in the present study is expected to treat the steroid-induced skin damages.

In this study, the anti-oxidant activity, elastase inhibitory activity, and skin moisturizing effect of mixed extracts of Acanthopanax senticosus and Citrus unshiu fermented with Bovista plumbea (B-MEAC) were evaluated to verify the availability as a material for inner beauty. The DPPH radical scavenging activity of B-MEAC was showed in a dose-dependent manner (SC50=156.1±0.82 ㎍/ml). Also, B-MEAC inhibited the elastase activity in a concentration-dependent manner (p<0.001). To study the effect of B-MEAC on mouse skin hydration, skin moisture content and transepidermal water loss (TEWL) measured. As a result, skin moisture content increased (p<0.001) and TEWL decreased (p<0.01) compared to the dry-induced control group. The effect on the change of collagen fibers in the dry-induced mouse skin was examined through Masson's trichrome staining. In the group administered with B-MEAC, the amount of collagen relatively increased compared to the control group, and the intensity of blue color increased. The effect on the moisturizing function of the dry-induced mouse skin was examined by Western blot method. In the group administered with B-MEAC, the expression of matrix metalloproteinase-1 (MMP-1) protein decreased compared to the control group. In addition, the expression level of collagen1A1 (COL1A1), hyaluronan synthase-2 (HAS2), filaggrin, and aquaporin-3 (AQP3) recovered (p<0.001). Therefore, these results suggest the potential of B-MEAC as a skin hydration agent for inner beauty.
In this study, the antibacterial activity and the moisturizing effect of cream contaning Persicaria hydropiper L. extract were investigated by clinical trial. MIC values of ethyl acetate fraction from Persicaria hydropiper on P.acnes, S.aureus, P.ovale were 0.13~0.25%. The results showed that the antibacterial activity of the ethyl acetate fraction was higher than or equal to the methyl paraben and quercetin. The cream containing the ethyl acetate fraction of Persicaria hydropiper L. extracts was formulated for skin hydration effect. Also, the transepidermal water loss (TEWL) and the water contents in skin were measured. The cream containing Persicaria hydropiper L. extract was applied to the right lower arm. After 180 min, TEWL of parts was decreased as $6.5\;g/m^2h$ (experimental cream) and $7.5\;g/m^2h$ (placebo cream) respectively. And the water contents in skin were increased by 2~4% than the placebo cream. These results indicate that extract/fractions of Persicaria hydropiper L. can function as high potential as bactericide against the skin pathogenic bacteria and the increase of skin hydration of the cream containing extract could be applicable to new functional cosmetics for antiaging.
Allergic contact dermatitis (ACD) is an inflammatory skin disease and regarded as a prototype of T-cell mediated delayed-type hypersensitivity reactions. Aroma Oil Complex (AOC) is composed of lavender true oil, chamomile roman oil and tea tree oil. This study was performed to assess the effects of AOC in a canine model of ACD. ACD was induced on the back of dogs induced by sensitization and repeated application by 2,4-dinitro-1-chlorobenzene (DNCB). Topical treatment of AOC was applied once a day for 8 days and skin biophysical parameters including transepidermal water loss (TEWL), skin hydration, skin thickness and erythema index, were measured every two days during experimental periods. Histopathology and immunohistochemistry were performed to evaluate the anti-inflammatory effect. In skin biophysical parameters, TEWL, skin hydration, skin thickness and erythema index were significantly increased, with a maximum increase appeared on day 2 (p<0.05). After the completion of AOC treatment, skin biophysical parameters were significantly reached those of baseline in a time-dependent manner (p<0.05). In histopathology, marked increases of epidermal thicknesses were induced after DNCB challenge with numerous inflammatory cell infiltrations and edematous changes, decreases of connective tissue occupied regions in dermis. In addition, marked increases of cytokine - tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) and interferon-${\gamma}$ (IFN-${\gamma}$)-immunoreactivities in the dermis and of apoptotic markers - caspase-3 and PARP-immunoreactivities in the epidermis were observed in DNCB control as compared with intact control, respectively (p<0.01). The decrease of infiltrated inflammatory cells and related decreases of pro-inflammatory cytokine immunoreactivities were observed in AOC treated skin (p<0.01). Based on these findings, AOC may have anti-inflammatory and alleviatory effects in the allergic contact dermatitis.
Physiological lipid mixtures comprised of cholesterol, ceramide and free fatty acid better maintain epidermal homeostasis and have been recently used for dermatoses induced by skin barrier damage, for example for atopic dermatitis and xerotic skin. Itching and dry atopic dermatitis of the skin may be related to altered skin barrier function. In a previous study, the use of multi-lamellar emulsion (MLE), which is a lipid mixtures containing cholesterol, pseudoceramide and free fatty acid, has been shown to accelerate the recovery of the epidermal permeability barrier. In this study, we assessed the efficacy of MLE compared with a currently used anti-itch moisturizer (AIM), the active ingredients of which are menthol and camphor, on barrier recovery after barrier disruption. To clarify the effect of MLE and AIM after acute barrier perturbation, we measured the relation between transepidermal water loss (TEWL) and the barrier recovery rate at 3, 6, 24, and 48 hours after tape stripping hairless mice and then observed changes in the stratum corneum (SC), including the intercellular lipid structure and secretion of lamellar bodies, by electron microscopy. MLE treated skin recover skin barrier function more rapidly, and AIM treated skin delayed barrier repair. Morphological changes in the epidermis, of MLE treated skin revealed well-conserved lipid multi-lamellar structures at 24 h after tape stripping, whereas AIM treated skin showed altered lamellar bilayers within the SC interstices at 48 h. In addition, MLE treated skin showed an increase in the number of LBs and in their secretions and a decrease in the number of SC layers versus AIM treated skin. These results suggest that MLE may accelerate the production of an epidermal permeability barrier in hairless mice by increasing the number and secretion of LB and improve the dryness and itch associated with an altered epidermal permeability barrier.

In this study, we investigated the effects of Sedum sarmentosum extract on the expression of hyaluronan synthase (HAS) genes and hyaluronan (HA) production in HaCaT keratinocytes. We also assessed water content (electrical capacitance) and transepidermal water loss (TEWL) in human skin after topical treatment with Sedum sarmentosum extract. Sedum sarmentosum extract increased expression of HAS-2 and HAS-3 genes in HaCaT cells, when assayed by real-time reverse-transcriptase polymerase chain reactions (RT-PCR). Sedum sarmentosum extract induced HA production in HaCaT cells, when determined by enzyme-linked immunosorbent assay (ELISA). Finally, treatment of Sedum sarmentosum extract on human skin increased the skin hydration and decreased TEWL when measured using Corneometer and Tewameter. Our study suggests that Sedum sarmentosum extract should be a very useful cosmetic ingredient, as a skin moisturizer.
