Atopic dermatitis, also called congenital fever, is a allergic eczema of chronic itching disease. It is a recurrent and familial disease and appears on a wide age group from infant to adult. It is very common, and the ratio of occurrence is about $9{\~}l2\%$ of a child. However. it is showing trend of continuous increase by social and natural environment, food culture, and life style, recently. The human skin plays a barrier role against a physical and chemical stimulus from external environment. According to the latest study, the decreased amount of ceramide in horny layer impairs the bier function and moisture-maintaining function of skin in atopic dematitis patient. Ceramide is a kind of the sphingolipid in which a fatty acid is connected to sphingosin. Ceramide constitutes about $40\%$ of total lipid between keratinocytes and has the function of defense wall and building regular structure to suppress moisture vaporization in horny layer. In horny layer of skin a comified cell is composed of multi-layer structure of a brick shape, and, as for this cornified cell, it is strongly connected by ceramide, cholesterol, and free fatty acid. Here, we described the effects of a cream containing ceramide on the recovery of skin harrier function of atopic dermatitis patient. The safety and efficacy of latex and liquid formula were evaluated as cosmetics for atopic dermatitis. The latex products was composed of intercellular lipid components-ceramide, cholesterol, and free fatty acid-to restore skin barrier function in atopic dermatitis patients. The liquid one contained beta-glucan, magnolia extracts, and licolice extracts, which have skin immunomodulatory and anti-inflammatory effects. It is also confirmed that their possibility on new cosmetic market of atopic dermatitis.

This review summarizes the cause of allergy and control by lactic acid bacteria. Atopic diseases such as asthma, rhinitis, eczema and food allergy have increased in most industrialized countries of the world during the last 20 years. The reasons for this increase are not clear and different hypotheses have been assessed including increased exposure to sensitizing allergens or decreased stimulation of the immune system during critical periods of development. Probiotic bacteria, which beneficially affect the host by improving its microbial balance, may mediate anti-allergenic effects by immune stimulation. Although more clinical evidences are required, the possible role of specific LAB strains in the prevention of allergic diseases has become more evident. since the role of functional food is important for prevention, it is expected for the more anti-allergy fermented milk products to be on the market.

Atopic dermatitis is a chronic, allergic inflammatory skin disease that is accompanied by pruritic chronic eczema and markedly increased levels of inflammatory cells in endothelial cells. Arctium lappa L. is a popular edible vegetable cultivated in Asia. This study examined the effect of butanol extracts of A. lappa (ALBE) on the expression of adhesion molecule, ICAM-1 and the production of NO-iNOS induced by TNF-alpha in A549 endothelial cells. We also studied the effects of ALBE on the proliferation of keratinocyte. We observed significant inhibition of NO-iNOS production in dose-dependant manners and ALBE at $100\;{\mu}g$/mL suppressed the expression of ICAM-1 in TNF-${\alpha}$-induced A549 cells. In addition, the treatment of ALBE for 48 hrs increased the proliferation of HaCaT keratinocytes. These results support that ALBE has an anti-inflammatory effects for the treatment of atopic dermatitis.

This study was conducted to investigate the actual state of the food allergy and food behavior in adults by using a questionnaire. The subjects of this study were consisted of 207 males and 355 females in Gyeongbuk area. The results are as follows: Among the respondents, 54.9% kept up with proper eating habits, 41.2% knew how much they would have to eat appropriately in a day, and women ate more milk and snacks than men in a day and men ate more meat than women. 58.3% of men and 46% of women were eating 3 meals a day. This finding indicated that women skipped the meal more than men. 77.2％ of the respondents skipped their breakfast, 13.5％ the lunch, and 9.3% the dinner. 48.5％ of men and 28.8% of women evacuated over 8 times a week(p<0.001). Eczema was the allergy symptom which broke out the most highly in both male and female; 25% of men and 29.9% of women. Atopic dermatitis and pollen allergy broke out similarly in both male and female. Allergic rhinitis occurred twice more in men than in women. Asthma broke out in men about three times more than in women. 36.3% of men and 46.5% of women visited a doctor when they had an allergic reaction. 40.9% of men and 40.7% of women believed that the allergy was caused mainly by the dust in the house and mites. The other factors, which caused the allergic reaction, were thought to be the specific food and the pollution from cars and factories by men and the specific food and others by women. 35.4% of men and 44.2% of women ate homemade food to prevent allergies.

The aim of the present study is to investigate the cytokine production inhibitory effect of a Dictamni Radicis Cortex (DRC). DRC has been commonly used as important medicinal herb in China and it used to control eczema, atopic dermatitis, fever and inflammatory diseases. Inflammation, such as a bacterial infection in vivo metabolites, such as external stimuli or internal stimuli to the defense mechanisms of the biological tissue a variety of intracellular regulatory factors deulin inflammatory TNF-${\alpha}$, IL-$1{\beta}$, IL-6, IL-8, such as proinflammatory cytokines, prostagrandin, lysosomal enzyme, free radicals are involved in a variety of mediators. The present study was designed to determine the effect of the DRC on proinflammatory factors such as NO, iNOS expression and TNF-${\alpha}$, IL-$1{\beta}$, IL-6 in lipopolysaccharide (LPS) - stimulated RAW264.7 cells. The cell toxicity was determined by MTS assay. To evaluate of anti-inflammatory effect of DRC, amount of NO was measured using the NO detection kit and the iNOS expression was measured by reverse transcriptase polymerase chain reaction (RT-PCR). And proinflammatory cytokines were measured by ELISA kit. As a result, the DRC reduced NO, iNOS expression and TNF-${\alpha}$, IL-$1{\beta}$, IL-6 production without cytotoxicity. Our results suggest that the DRC may have an anti-inflammatory property through suppressing inflammatory mediator productions.

Allergic rhinitis is a common disease of childhood characterized by nasal, throat, and ocular itching, rhinorrhea, sneezing, nasal congestion. Those affected with allergic rhinitis often suffer from associated inflammatory conditions of the mucosa, such as allergic conjunctivitis, rhinosinusitis, asthma, otitis media with effusion, and other atopic conditions, such as eczema and food allergies. Allergic rhinitis must be diagnosed and treated properly to prevent complications and impaired quality of life. Despite a high prevalence, allergic rhinitis isoften undiagnosed and inadequately treated, especially in the pediatric population. The first step in treatment is environmental control when appropriate. It may be difficult to eliminate all offending allergens effectively to reduce symptoms, so medications are often required. Many different classes of medications are now available, and they have been shown to be effective and safe in a large number of well-designed, clinical trials. Antihistamines are effective in treating immediate symptoms of sneezing, pruritus, watery eyes, and rhinorrhea. Second generation antihistamines are the preferred antihistamines because of their superior side effect profile. Thus, decongestants are commonly used with oral antihistamines. Intranasal corticosteroids are the most effective therapy for allergic rhinitis. Leukotriene modifier may be as effective as antihistamines in treating allergic rhinitis symptoms. Cromolyn sodium is an option for mild disease when used prophylactically, and ipratropium bromide is effective when rhinorrhea is the predominant symptom. When avoidance measures and medications are not effective, specific immunotherapy is an effective alternative. Only immunotherapy results in sustained changes in the immune system. Because of improved understanding of the pathogenesis, new and better therapies may be forthcoming. The effective treatment of allergic rhinitis in children will reduce symptoms and will improve overall health and quality of life, making a happier, healthier child.

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.

BACKGROUND/OBJECTIVES: Gastrodia elata Blume (GEB), a traditional herbal medicine, has been used to treat a wide range of neurological disorders (e.g., paralysis and stroke) and skin problems (e.g., atopic dermatitis and eczema) in oriental medicine. This study was designed to investigate whether GEB extract inhibits melanogenesis activity in murine B16F10 melanoma. MATERIALS/METHOD: Murine B16F10 cells were treated with 0-5 mg/mL of GEB extract or $400{\mu}g/mL$ arbutin (a positive control) for 72 h after treatment with/without 200 nM alpha-melanocyte stimulating hormone (${\alpha}$-MSH) for 24 h. Melanin concentration, tyrosinase activity, mRNA levels, and protein expression of microphthalmia-associated transcription factor (MITF), tyrosinase, tyrosinase-related protein (Trp)1, and Trp2 were analyzed in ${\alpha}$-MSH-untreated and ${\alpha}$-MSH-treated B16F10 cells. RESULTS: Treatment with 200 nM ${\alpha}$-MSH induced almost 2-fold melanin synthesis and tyrosinase activity along with increased mRNA levels and protein expression of MITF, tyrosinase, Trp1 and Trp2. Irrespective of ${\alpha}$-MSH stimulation, GEB extract at doses of 0.5-5 mg/mL inhibited all these markers for skin whitening in a dose-dependent manner. While lower doses (0.5-1 mg/mL) of GEB extract generally had a tendency to decrease melanogenesis, tyrosinase activity, and mRNA levels and protein expression of MITF, tyrosinase, Trp1, and Trp2, higher doses (2-5 mg/mL) significantly inhibited all these markers in ${\alpha}$-MSH-treated B16F10 cells in a dose-dependent manner. These inhibitory effects of the GEB extract at higher concentrations were similar to those of $400{\mu}g/mL$ arbutin, a well-known depigmenting agent. CONCLUSIONS: These results suggest that GEB displays dose-dependent inhibition of melanin synthesis through the suppression of tyrosinase activity as well as molecular levels of MITF, tyrosinase, Trp1, and Trp2 in murine B16F10 melanoma. Therefore, GEB may be an effective and natural skin-whitening agent for application in the cosmetic industry.

Background and Objectives: Allergic contact dermatitis is a common environmental health issue and seriously affect the patient's quality of life. The more our environment industrialized, the number of material that could cause the allergic contact dermatitis has been increased, consequently the prevalence of allergic contact dermatitis has been increased. In oriental medicine, clinically Chogam-Tang has been used fur the treatment of allergic dermatitis, eczema, atopic dermatitis etc. The objective of this study is to investigate the effects of Chogam-Tang on allergic contact dermatitis Meterial and Methods: Fifteen Sprague-Dawley rats were divided into three groups: normal, control, experimental group. Control and experimental group were induced allergic contact dermatitis, by DNCB. Experimental group was orally administered the Chogam-Tang. Each group was observed after 24, 48 and 72 hours. Contact hypersensitivity assay, melanin-erythema measurement, pH measurement skin moisture measurement and biopsy were performed. Results: 1. In contact hypersensitivity assay, experimental group showed decreased ear swelling compared with control group at 48hours. 2. ln melanin measurement there was no difference in three groups. 3. In erythema measurement experimental group showed reduction at 48. 72 hours. 4. In pH measurement, experimental group and control group showed increase in pH but there was no statistical significance. 5. In skin moisture measurement, experimental group showed higher skin moisture level than control group at 24 hours and showed lower skin moisture level at 72 hours, but there was no statistical significance. 6. In biopsy, experimental group showed decrement of Iymphocyte as time goes by, and regeneration of keratin layer was increased compared with normal group. Conclusions: Chogam-Tang shows anti-inflammatory effect in biopsy, improves hydration levels of skin, decreases erythema level on allergic contact dermatitis.
