  • Allergic diseases such as asthma, allergic rhinitis, atopic dermatitis, and food allergy, are most common chronic, noncommunicable diseases in childhood. In the past few decades, the prevalence has increased abruptly worldwide. There are 2 possible explanations for the rising prevalence of allergic diseases worldwide, that an increased disease-awareness of physician, patient, or caregivers, and an abrupt exposure to unknown hazards. Unfortunately, the underlying mechanisms remain largely unknown. Despite the continuing efforts worldwide, the etiologies and rising prevalence remain unclear. Thus, it is important to identify and control risk factors in the susceptible individual for the best prevention and management. Genetic susceptibility or environments may be a potential background for the development of allergic disease, however they alone cannot explain the rising prevalence worldwide. There is growing evidence that epigenetic change depends on the gene, environment, and their interactions, may induce a long-lasting altered gene expression and the consequent development of allergic diseases. In epigenetic mechanisms, environmental tobacco smoke (ETS) exposure during critical period (i.e., during pregnancy and early life) are considered as a potential cause of the development of childhood allergic diseases. However, the causal relationship is still unclear. This review aimed to highlight the impact of ETS exposure during the perinatal period on the development of childhood allergic diseases and to propose a future research direction.

  • To evaluate whether chaff vinegar liquor (CVL) has potential in ameliorating allergic symptoms in mice, we tested the anti-allergic activities with a DNFB (dinitrofluorobenzene)-induced allergic mouse model. The DNFB-induced allergic symptoms were reduced by 20% compared to the control by chaff vinegar liquor supplemented with Perilla frutescens var. acuta. Allergic symptoms were examined by measuring the width of epidermis swelling. The hematoxyline & eosin (H&E) staining also revealed that the chaff vinegar liquor dramatically decreased the allergic symptoms in the epidermis of the ear. These results collectively suggest that the chaff vinegar liquor supplemented with P. frutescens var. acuta has potential in ameliorating allergic symptoms, showing that the liquor could be a useful biomaterial(s) for the nutraceutical or cosmetic industries.

  • Ginseng (the root of Panax ginseng Meyer) fermented by Lactobacillus plantarum has been found to attenuate allergic responses in in vitro and in vivo experimental models. Ginseng has been reported to also possess various biological functions including anti-inflammatory activity. The present study was aimed at comparing the anti-allergic effect of ginseng and fermented ginseng extracts on IgE-mediated passive cutaneous anaphylaxis in vitro in a murine cell line and in vivo in mice. Fermented ginseng extract (FPG) showed higher inhibitory effect against in vitro and in vivo allergic responses when compared with ginseng extract (PG). The secretion of ${\beta}$-hexosaminidase and interleukin (IL)-4 from the IgE-DNP-stimulated RBH-2H3 mast cells were significantly (p < 0.05) inhibited by FPG treatment, and this effect was concentration-dependent. Further, MKK4 activation and subsequent JNK phosphorylation were attenuated by FPG treatment. The inhibitory effect of FPG on the in vitro allergic response was verified in vivo against IgE-DNP-induced passive cutaneous anaphylaxis in a mouse model. These data indicated that the fermentation of ginseng with L. plantarum enhanced its anti-allergic effects both in vitro and in vivo. We predict that compositional changes in the ginsenosides caused by the fermentation may contribute to the change in the anti-allergic effects of ginseng. The results of our study highlight the potential of the use of FPG as a potential anti-allergic agent.

  • Objectives : In this study, we investigated anti-allergic effect of Okbyeongpungsan-Hap-Changijasan (KOB01) in allergic rhinitis(AR) experimental animals and mast cells. Methods : The potential anti-allergic effect of KOB01 was investigated in a rat model of compound 48/80-induced systemic anaphylactic shock and a mouse of ovalbumin(OVA)-induced AR, and human mast cell line, HMC-1 culture. Each animals were divided into four groups: normal, control, KOB01-treated(100 and 200 mg/kg) and anti-histamine drug, dosodium cromoglycate (DSCG)-treated(50 mg/kg). Animals were orally treated with KOB01 and DSCG and intraperitoneally injected with compound 48/80($10\;{\mu}g/kg$) or sensitized with 0.1% OVA. The mortality and serum histamine levels were measured in compound 48/80-induced anaphylatic rats. The histological changes in nasal mucosa were investigated in OVA-induced AR mice. Also, mast cell degranulation was observed in compound 48/80-stimulated HMC-1 cells. Results : KOB01 increased mortality and significantly decreased serum histamine levels in compound 48/80-induced anaphylatic rats. The abnormal histological changes such as expansion of grandular cells and hypertrophy of epithelium in nasal mucosa of OVA-induced AR mice was improved by KOB01 treatment nearby a normal group. Therefore, KOB01 inhibited compound 48/80-induced degranulation in HMC-1 cells. Conclusions : These results indicate that KOB01 decrease allergic response through suppressing the mast cell activation in AR and suggest a potential role for KOB01 as a source of anti-allergic agents for use in allergic disorders including of AR.

  • Although Oriental medicines have long been used effectively in treating many diseases throughout the world, the pharmacological mechanisms of most Oriental medicines used have not been defined. As part of our continuing search for biologically active antiallergic drugs from natural sources, Oriental medicines were analyzed. Some Oriental medicines have been used against various allergic diseases for generations, and still occupies an important place in traditional medicine in Korea. It is also still unclear how Oriental medicine prevents allergic disease in experimental animal models. Some Korean folk medicines inhibited the mast cell-mediated allergic reaction. This review summarizes the effective folk medicine in experimental effect of allergic reaction. Potential antiallergic folk medicines include: Poncirus trifoliata; Siegesbeckia glabrescence; Solanum lyratum; Aquilaria agallocha; Ulmi radicis; Polygonum tinctorium; Hwanglyun-Haedok-Tang; Rehmannia glutinosa; Kum- Hwag-San; Syzygium aromaticm; Spirulina platensis; Sosiho-Tang; Sinomenium acutum; Schizonepta tenuifolia; Shini-San; Magnoliae flos; Sochungryoung-Tang; Oryza sativa; Cryptotympana atrata; Salviae radix; Rosa davurica; Asiasari radix; Chung-Dae-San; and Cichorium intybus. Understanding the mechanisms of action for these Oriental medicines can permit drug development and laying of the ground-work for evaluating potential synergistic effects by addition and subtraction of prescriptions.

  • Allergic diseases have rapidly increased in recent years. Mast cells play a critical role in IgE-mediated allergy responses and, therefore, closely associated with rhinitis, asthma, and atopic dermatitis. We studied anti-allergic effect of Penthorum chinense extract (PCE) in vitro and in vivo. PCE inhibited the degranulation of mast cells by antigen stimulation and its effect was dose-dependent and reversible in mast cells. PCE also suppressed the production of inflammatory cytokines such as TNF-${\alpha}$ and IL-4 by antigen in mast cells. Mechanistically, PCE inhibited the activation of Syk/LAT pathway which is a key signaling pathway for the activation of mast cells by antigen. Notably, PCE suppressed IgE-mediated allergic responses by antigen in mice. These results strongly suggest that PCE is a potential candidate for anti-allergic treatment.

  • The prevalence of allergic disorders has dramatically increased over the past decade, particularly in developed countries. Apart from gastrointestinal disorders, neoplasia, genital and dermatological diseases etc., dysregulation of gut microbiota (dysbiosis) has also been found to be associated with increased risk of allergies. Probiotics are increasingly being employed to correct dysbiosis and, in turn, to modulate allergic diseases. However, several factors like strain variations and effector metabolites or component of them in a bacterial species can affect the efficacy of those as probiotics. On the other hand, host variations like geographical locations, food habits etc. could also affect the expected results from probiotic usage. Thus, there is a glaring deficiency in our approach to establish probiotics as an irrefutable treatment avenue for suitable disorders. In this review, we explicate on the reported probiotics and their effects on certain allergic diseases like atopic dermatitis, food allergy and asthma to establish their utility. We propose possible measures like elucidation of effector molecules and functional mechanisms of probiotics towards establishing probiotics for therapeutic use. Certain probiotics studies have led to very alarming outcomes which could have been precluded, had effective guidelines been in place. Thus, we also propose ways to secure the safety of probiotics. Overall, our efforts tend to propose necessary discovery and quality assurance guidelines for developing probiotics as potential immunomodulatory 'Pharmabiotics.'

  • Asthma is characterized by chronic inflammation and respiratory tract remodeling. Peroxisome proliferator-activated receptors (PPARs) play important roles in the pathogenesis and regulation of chronic inflammatory processes in asthma. The role of PPARγ has been studied using synthetic PPARγ agonists in patients with asthma. However, involvement of PPARα/δ has not been studied in asthma. In the present study, we investigated if elafibranor, a PPARα/δ dual agonist, can modulate ovalbumin (OVA)-induced allergic asthma, which is a potential drug candidate for non-alcoholic fatty liver in obese patients. Elafibranor suppresses antigen-induced degranulation in RBL-2H3 mast cells without inducing cytotoxicity in vitro. In mice with OVA-induced allergic asthma, the administration of elafibranor suppressed OVA-induced airway hyper-responsiveness at a dose of 10 mg/kg. Elafibranor also suppressed the OVA-induced increase in immune cells and pro-inflammatory cytokine production in the bronchoalveolar lavage fluid (BALF). Histological studies suggested that elafibranor suppressed OVA-induced lung inflammation and mucin hyper-production in the bronchial airways. In addition, elafibranor suppressed OVA-induced increases in serum immunoglobulin E and IL-13 levels in BALF. Conversely, the present study suggests that elafibranor has the potential for use in patients with allergic asthma.

  • Various kinds of positive effects of green tea extracts had been studied for long time which included anti-inflammation, anti-aging, and cardiometabolic effects. Although topical steroid and non-steroidal calcineurin inhibitors may control clinical symptoms of allergic contact dermatitis, some of patients also present allergic reaction to these topical agents. Therefore, we have tried green tea extracts for managing this skin disorder with expectation of anti-inflammatory effect without potential side effects including skin irritation and toxic responses. The toxicity test of green tea extract also did not show any sign of irritation in the skin throughout the test period. Moderate severity of allergic contact dermatitis presented satisfactory clinical outcome at second week follow-up which was final visit of outpatient. This result mean that green tea extract has a positive effect for managing allergic contact dermatitis but its potency and efficacy seem to be so not strong enough to control moderate severity allergy skin lesion. In this pilot study, we were able to conclude that green tea cell extracts might be applied for potential anti-inflammatory soaking without skin toxicity.
