  • Staphylococcus spp. is one of the most common bacteria isolated from the lesions of atopic dermatitis (AD) in humans, and their colonization is known to be a possible trigger factor of clinical signs. The aim of this study was to determine the prevalence of Staphylococcus spp. in canine AD (CAD), the types of exotoxins present, and their relation with the clinical severity of CAD. From 79 dogs with AD, 72 samples of Staphylococcus spp. were isolated (91.1%), and 65 (90.3%) were confirmed as Staphylococcus pseudintermedius. Concerning the profile of the exotoxin gene, 50 isolates (69.4%) contained at least one exotoxin gene, and 28 isolates (56%) were found to contain more than 2 different exotoxins. There was a significant difference in clinical severity with the presence of staphylococcal exotoxins (P=0.028), whereas no correlation was found with the presence of Staphylococcus spp. (P=0.598). The clinical severity of CAD increased only in relation to staphylococcal enterotoxin D (SED) and exfoliative toxins (P<0.05). Some clinical evaluation criteria (erythema, papule/pustule) were correlated with the presence of the exotoxin gene (P<0.05). This study showed that the high prevalence of Staphylococcus spp. and staphylococcal exotoxins in lesions from dogs with AD may be regarded as an important trigger factor for exacerbation of the clinical signs of CAD.

  • Atopic dermatitis (AD) is a form of allergic skin inflammatory characterized by late eczematous skin lesions. The incidence of AD is increasing, and it causes problems with administrative costs. Therefore, development of an AD treatment with no side effects is needed. The purpose of this study was to evaluate tuna heart ethanol extract (THEE), a functional extract from by-product of tuna. AD was induced by spreading 2,4-dinitrochlorobenzene (DNCB) on the backside of BALB/c mice. The effect of THEE was tested by measuring skin clinical severity score, secretion of cytokines and IgE, and proliferation. Secretion of $TNF-{\alpha}$, IL-4, IL-5, IL-13, and IgE significantly decreased in a THEE-independent manner. In contrast, levels of IL-10 and $IFN-{\gamma}$ significantly increased in mice sera and splenocytes. In addition, THEE alleviated AD symptoms compared to the DNCB only group. In conclusion, these results demonstrate that THEE has an inhibitory effect on AD and may be a useful substance for the development of cosmeceuticals.

  • Wounds are commonly created during almost every kind of surgery, trauma and skin diseases. Delayed wound healing affects a plenty of patients and requires prolonged treatments that seriously reduce the quality of life for patients. Skin damage involving large areas or great severity can lead to disability or even death. Wound healing involves a complicated series of actions, of various tissues and cell lineages, concerning inflammation, migration, proliferation, reepithelialization, and remodeling. Sopung-san is reported to have anti-inflammatory effect and has been used for various skin diseases such as allergic dermatitis and atopic dermatitis. In this study, the hypothesis that oral treatment with Sopung-san could enhances healing potential on rat full thickness skin wounds was tested. Twenty young male Sprague-Dawley rats were used for the studies. A full-thickness skin wound was made on the dorsal skin of the rats. Either Sopung-san water extract (SPS) or saline (Control) was orally administrated every day. The wound area was measured and the percentages of wound contraction, wound healed and wound epithelization were calculated. Wound tissue samples were excised following injection for histopathological and immunohistological examination. Wound area in rats of SPS group significantly was decreased compared to Control. SPS group showed significant promotion of wound healing compared to Cotrol group in the percentages of wound contraction, wound healed and wound epithelization. Histopathological examination revealed that SPS induces neo-vascularization potential in wound healing process. SPS treatment in rats significantly accelerated cutaneous wound healing in the neo-vascularization process by increasing VEGF and $TGF-{\beta}1$ synthesis. The results suggest that Sopung-san affects key cellular processes responsible for wound repair and point to a unique potential for this molecule in the therapy of skin wounds, particularly as an angiogenic agent.

  • Although the incidence and severity of atopic dermatitis (AD) is steadily increasing at an alarming rate, its pathogenic mechanisms remain poorly understood yet. Recently, we found that the expression of Grb7 protein was markedly decreased in AD patients using proteomic analysis. In the present study, human Grb7 gene was fused with PEP-1 peptide in a bacterial expression vector to produce a genetic in-frame PEP-1-Grb7 fusion protein. The expressed and purified PEP-1-Grb7 fusion proteins transduced efficiently into skin cells in a time- and dose-dependent manner when added exogenously in culture media. Once inside the cells, the transduced PEP-1-Grb7 protein was stable for 48 h. In addition, transduced PEP-1-Grb7 fusion protein markedly increased cell viability in macrophage RAW 264.7 cells treated with LPS by inhibition of the COX-2 expression level. These results suggest that the PEP-1-Grb7 fusion protein can be used in protein therapy for inflammatory skin disorders, including AD.

  • The worldwide prevalence and severity of allergic diseases including atopic and contact dermatitis has increased dramatically over the past decade, especially in developed countries. Mast cells are important effector cells in allergic reactions. The purpose of this study was undertaken to investigate the anti-allergic and anti-pruritic effects of Diospyros lotus leaf extract (DLE). DLE was prepared by extracting with distilled water. In the present study, we investigated the effect of DLE on the production of tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin-$1{\beta}$ (IL-$1{\alpha}$) and histamine in rat peritoneal mast cells (RPMCs), and on the skin lesion, leukocyte infiltration and scratching behavior in mice. Phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187 significantly increased TNF-${\alpha}$ and IL-$1{\beta}$ production compared with media control. However, TNF-${\alpha}$ and IL-6 production increased by PMA plus A23187 treatment were significantly inhibited by DLE in a dose-dependent manner. DLE also inhibited the histamine release from RPMCs stimulated by compound 48/80, which promotes histamine release. Moreover, DLE administration had an inhibitory effects on the scratching behavior induced by pruritogen (compound 48/80, histamine) in ICR mice. Furthermore, DLE inhibited the skin lesions, inflammatory and mast cells in hairless mice sensitized by 2,4-dinitrofluorobenzene (DNFB). DLE administration reduced the IL-4 and IgE production induced by DNFB sensitization in hairless mice. These results suggest that DLE has a potential use as a herb medicine for treatment against allergy and pruritus-related disease.

  • The worldwide prevalence and severity of allergic diseases including atopic dermatitis and asthma has increased dramatically over the past decade, especially in developed countries. Mast cells are important effector cells in allergic reactions. The purpose of this study was undertaken to investigate the anti-allergic activities of the extract of Duchesnea chrysantha (DCE). DCE was prepared by extracting with 80% ethanol. In the present study, we investigate the effect of DCE on the production of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-$1{\beta}$, IL-6, IL-8, and histamine in the human mast cell line (HMC-1 cells) and on the scratching behavior in hairless mice. Various concentrations of DCE were treated before the activation of HMC-1 cells with phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187. PMA plus A23187 significantly increased TNF-${\alpha}$, IL-$1{\beta}$, IL-6, and IL-8 production compared with media control. We also show that the increased cytokines such as TNF-${\alpha}$ IL-$1{\beta}$, IL-6, and IL-8 were significantly inhibited by DCE in a dose-dependent manner. Moreover, DCE inhibited the histamine release from HMC-1 cells stimulated by compound 48/80, which promotes histamine release. Futhermore, the administration of DCE reduced the scratching behavior induced by pruritogen (compound 48/80 or histamine) in hairless mice. These results suggest that DCE has a potential use as a medicinal plant for treatment against allergy-related disease.

  • Antibiotics are frequently administered during pregnancy. Although necessary to address acute infections, their use facilitates antibiotic resistance. Other associations have also been found with the use of antibiotics, such as perturbations of gut bacteria, delays in microbial maturation, and increased risks of allergic and inflammatory diseases. Little is known about how the prenatal and perinatal administration of antibiotics to mothers affects the clinical outcomes of their offspring. A literature search was conducted of the Cochrane, Embase, and PubMed engines. The retrieved articles were reviewed by two authors and verified for relevance. The primary outcome was the effect of pre- and perinatal maternal antibiotic use on clinical outcomes. Thirty-one relevant studies were included in the meta-analysis. Various aspects are discussed, including infections, allergies, obesity, and psychosocial factors. In animal studies, antibiotic intake during pregnancy has been suggested to cause long-term alterations in immune regulation. In humans, associations have been found between antibiotic intake during pregnancy and different types of infections and an increased risk of pediatric infection-related hospitalization. A dose-dependent positive association between pre- and perinatal antibiotic use and asthma severity has been reported in animal and human studies, while positive associations with atopic dermatitis and eczema were reported by human studies. Multiple associations were identified between antibiotic intake and psychological problems in animal studies; however, relevant data from human studies are limited. However, one study reported a positive association with autism spectrum disorders. Multiple animal and human studies reported a positive association between pre- and perinatal antibiotic use by mothers and diseases in their offspring. Our findings have potentially significant clinical relevance, particularly considering the implications for health during infancy and later in life as well as the related economic burden.
