OBJECTIVETo study the genera and seasonal distribution of airborne pollen in Hubei province of China, and its relationship with pollinosis.
METHODSFrom November 2003 to October 2004, an airborne pollen investigation was performed in 16 chosen areas in 12 cities of Hubei province using gravity sedimentation technique. Meanwhile, univalent skin prick tests of pollens were performed and the invasion season was studied on 2,300 patients with pollinosis. Among them, 352 cases underwent the airway responsiveness measurements, and the correlation between airway responsiveness and results of pollen count was analyzed.
RESULTSA total of 61 pollen genera were observed and 257,520 pollens were collected. The peak of airborne pollen distribution occurred in two seasons each year: spring (March and April) and autumn (from August to October). The attack of pollinosis corresponded to the peak of pollen distribution. There was a significantly negative relationship between the provocation dose causing a 20% decrease of forced expiratory volume in one second (FEV1) from baseline and airborne pollen concentration (r= -0.6829, P < 0.05).
CONCLUSIONThis study provides useful information for airborne pollen epidemiology of Hubei province, and it provides important insights to clinical prevention, diagnosis, and treatment of pollen-related allergic diseases.

Mugwort and ragweed pollens have been considered as important respiratory allergens in Korea. These two pollens are abundant in the air of Seoul from August through October. Many ragweed-sensitive patients have shown concurrent sensitivities to mugwort pollen. However the antigenic relationship between these two pollens has not been clarified. To observe the cross-reactivity between them, we developed polyclonal anti-mugwort and anti-ragweed antibodies by immunization on New Zealand white rabbits, and performed crossed immunoelectrophoresis(CIE) with two pollen extracts. Five precipitation lines were formed by mugwort and anti-mugwort antibody. One precipitation line was formed by ragweed and anti-ragweed antibody. There was no reaction from mugwort and anti-ragweed antibody, and from ragweed and anti-mugwort antibody. These results indicate that there is no cross-antigenicity between mugwort and ragweed pollens.

PURPOSE: The occurrence of pollen allergy is subject to exposure to pollen, which shows regional and temporal variations. We evaluated the changes in pollen counts and skin positivity rates for 6 years, and explored the correlation between their annual rates of change. MATERIALS AND METHODS: We assessed the number of pollen grains collected in Seoul, and retrospectively reviewed the results of 4442 skin-prick tests conducted at the Severance Hospital Allergy-Asthma Clinic from January 1, 2008 to December 31, 2013. RESULTS: For 6 years, the mean monthly total pollen count showed two peaks, one in May and the other in September. Pollen count for grasses also showed the same trend. The pollen counts for trees, grasses, and weeds changed annually, but the changes were not significant. The annual skin positivity rates in response to pollen from grasses and weeds increased significantly over the 6 years. Among trees, the skin positivity rates in response to pollen from walnut, popular, elm, and alder significantly increased over the 6 years. Further, there was a significant correlation between the annual rate of change in pollen count and the rate of change in skin positivity rate for oak and hop Japanese. CONCLUSION: The pollen counts and skin positivity rates should be monitored, as they have changed annually. Oak and hop Japanese, which showed a significant correlation with the annual rate of change in pollen count and the rate of change in skin positivity rate over the 6 years may be considered the major allergens in Korea.

OBJECTIVEThe custom-homebuilding company, Cosmic Garden Co. Ltd., located in Okayama City, Japan was established in 1997 and uses specific natural ore powder (SNOP) in wall materials and surveys customers in order to improve allergic symptoms.
METHODSTo investigate the biological effects of SNOP, patients with a pollen allergy were recruited to stay in a room surrounded by cloth containing SNOP (CCSNOP), and their symptoms and various biological parameters were compared with those of individuals staying in a room surrounded by control non-woven cloth (NWC). Each stay lasted 60 min. Before and immediately after the stay, a questionnaire regarding allergic symptoms, as well as POMS (Profile of Mood Status) and blood sampling, was performed. Post-stay minus pre-stay values were calculated and compared between CCSNOP and NWC groups.
RESULTSResults indicated that some symptoms, such as nasal obstruction and lacrimation, improved, and POMS evaluation showed that patients were calmer following a stay in CCSNOP. Relative eosinophils, non-specific Ig E, epidermal growth factor, monocyte chemotactic protein-1, and tumor necrosis factor-α increased following a stay in CCSNOP.
CONCLUSIONThis ore powder improved allergic symptoms, and long-term monitoring involving 1 to 2 months may be necessary to fully explore the biological and physical effects of SNOP on allergic patients.

To elucidate the IgE binding site of mugwort (Artemisia vulgaris r.) pollen, pollen grains were frozen and fixed using a cryocut. They were incubated with antibodies according to the following sequence: Sera pool of individuals who showed mugwort-RAST class 3 or 4, biotin-labeled goat anti-human IgE antibody, streptavidin-peroxidase and diaminobenzidine. Then, they were observed under electron microscopy. The control section was incubated with the sera pool from individuals who showed a negative result on a skin prick test to mugwort pollen. Antigenic activity (electrondense line) was noted on the surface of the exine. There was no activity in cytoplasm or the intine layer. The control section was completely free of activity. It was suggested that the IgE binding site of mugwort pollen was present on the surface of the exine.

7.Allergic disease-related articles in Korean newspapers (1920–1972 year).
Allergy, Asthma & Respiratory Disease 2018;6(Suppl 1):S85-S89
PURPOSE: This study aimed to investigate which Korean newspaper articles were reported on allergic diseases before the establishment of the Korean Academy of Asthma, Allergy and Clinical Immunology (KAAACI). METHODS: This study was performed in 3 newspapers, Chosun Ilbo, DongA Ilbo, and JoongAng Ilbo, which were founded and used the databases established before the establishment of KAAACI in 1972. The databases were searched using 42 keywords associated with allergic diseases (allergy, asthma, rhinitis, etc.). RESULTS: Among the 42 keywords, there were only 7 that were able to search: allergy, urticaria, asthma, dermatitis, rhinitis, pollen and eczema. The total number of articles related to allergic diseases were 62, as follows: allergy (n=21), urticaria (n=15), asthma (n=8), dermatitis (n=8), rhinitis (n=5), pollen (n=3), and eczema (n=2). There were 31 articles in Chosun Ilbo, 9 in DongA Ilbo, and 22 in JoongAng Ilbo. The first allergic disease published in the newspapers was asthma on the article entitled “Treat the cause of asthma” (on page 8 of November 10, 1960 DongA Ilbo). The first article that used the term allergy appeared in a column entitled, “Childhood illness and allergy” (on page 4 of May 30, 1960 DongA Ilbo). CONCLUSION: Since 1920, articles related to allergic diseases published in the Korean newspapers increased every year. These articles may have appeared due to the increase in the prevalence of allergic disease and the pioneering efforts of senior allergy researchers.

Yonsei Medical Journal 1989;30(4):346-354
The pollen of Artemisia has been considered as the main late summer-autumn allergen source in this country. To identify its allergenic components, Artemisia princeps pollen extracts were separated by 10% sodium dodecylsulfate polyacrylamide gel electrophoresis (SDS-PAGE), and transferred to nitrocellulose membrane, where IgE binding components were detected by the reaction with sera of twenty Artemisia-allergic patients and 125I-anti-human IgE, sixteen components in the molecular range of 10,000 and 85,000 daltons were detected. Twelve bands bound to IgE from 50% of the sera tested, and two bands (37,000, 23,000 daltons) showed the highest (85%) frequency of IgE-binding in twenty sera tested. When the gel of SDS-PAGE with Artemisia pollen extracts was sliced into 11 allergenic groups (AG) and the protein of each AG was obtained by the gel elution method, the wormwool-RAST inhibition test showed that the AG 10 demonstrated to be the most potent, and the AG 7 was the next. Six AGs showed significant responses (more than 100% of wheal size to histamine, 1 mg/ml) on the skin prick test in more than 50% of the patients tested. It is suggested that electrophoretic transfer analysis with SDS-PAGE may be a valuable method for Artemisia allergen identification, and the possibility of partial purification of allergens by employing gel elution is discussed.

BACKGROUNDExcessive expression of thymic stromal lymphopoietin (TSLP) has been demonstrated in asthmatic airway epithelia and in nasal epithelia from animal models of allergic rhinitis (AR), but the evidence of expression of TSLP in nasal epithelial cells (NECs) of patients with AR is lacking. We aimed to investigate the expression of TSLP in NECs of patients with mugwort sensitive-seasonal AR and determine whether it is associated with severity of symptoms and the number of infiltrated eosinophils in nasal mucosa.
METHODSNECs specimens were obtained by scraping with plastic curettes from the nasal inferior turbinates of patients with mugwort pollen sensitive-seasonal AR (n = 22) and nonallergic controls (n = 11) during last peak mugwort pollen season. The severity of nasal symptom was assessed using a Visual Analog Scale (VAS). In addition, serum mugwort pollen IgE levels were tested from each patient. In situ hybridization (ISH) was performed to test the messenger RNA (mRNA) of TSLP in the NECs. Furthermore, immunohistochemical staining (IHC) was scored to evaluate the expression of TSLP and eosinophil cell count was made by May-Grünwald/Giemsa staining. The correlation between expression of TSLP and all other parameters was analyzed in this study.
RESULTSThe mRNA level of TSLP was significantly increased in NECs of patients with AR compared with the nonallergic control group (P < 0.05). In addition, IHC results showed that expression of TSLP in NECs from patients with AR was up-regulated which was correlated with VAS score (r = 0.598; P < 0.05) and nasal eosinophils count (r = 0.702; P < 0.05), but it was unrelated with mugwort pollen specific IgE level.
CONCLUSIONSThese preliminary findings indicate a potential relationship between TSLP expression, severity of symptoms and nasal eosinophils count in pathogenesis of AR, but TSLP expression did not correlate with mugwort pollen specific IgE level. The elevated expression of TSLP might play a critical role in local atopical responses of AR. In the future, the TSLP has the potential to be one of the most important molecular markers for AR diagnoses and assessment.
