<P>Asthma and atopy have a complex background that may result from the interaction of genes and the environment. Interleukin (IL)-10 is known to play various roles in immune-regulating and anti-inflammatory responses. The aim of this study was to evaluate the possible effect of the IL-10 promoter polymorphisms on susceptibility to childhood asthma. We recruited 333 patients with atopic asthma, 55 with nonatopic asthma, and 248 normal controls. We performed a genetic association study of three genetic polymorphisms (IL-10 -1082A>G, IL-10 -819T>C, and IL-10 -592A>C) of the IL-10 promoter. There was no difference between atopic asthma, nonatopic asthma, and normal controls with respect to allele, genotype, or haplotype frequencies of these IL-10 polymorphisms. However, the -1082A>G polymorphism and ATA haplotype in the IL-10 promoter gene were associated with airway hyper responsiveness (AHR) and the -819T>C, -592A>C, and ATA and ACC haplotypes were also shown to be related to serum eosinophil cationic protein (ECP). Our results suggest that the polymorphisms within the IL-10 promoter may have a disease-modifying effect in the asthmatic airway.</P>

Purpose: Cluster analyses on inflammatory markers of chronic rhinosinusitis (CRS) in Asians from multicenter data are lacking. This multicenter study aimed to identify the endotypes of CRS in Koreans and to evaluate the relationship between the endotypes and clinical parameters. Methods: Nasal tissues were obtained from patients with CRS and controls who underwent surgery. The endotypes of CRS were investigated by measuring interleukin (IL)-5, interferon (IFN)-γ, IL-17A, IL-22, IL-1β, IL-6, IL-8, matrix metalloproteinase-9, eotaxin-3, eosinophil cationic protein, myeloperoxidase (MPO), human neutrophil elastase (HNE), periostin, transforming growth factor-β1, total immunoglobulin E (IgE), and staphylococcal enterotoxin (SE)-specific IgE. We performed hierarchical cluster analysis and evaluated the phenotype, comorbidities, and Lund-Mackay computed tomography (LM CT) score in each cluster. Results: Five clusters and 3 endotypes were extracted from 244 CRS patients: cluster 1 had no upregulated mediators compared to the other clusters (mild mixed inflammatory CRS); clusters 2, 3, and 4 had higher concentrations of neutrophil-associated mediators including HNE, IL-8, IL-17A, and MPO (T3 CRS); and cluster 5 had higher levels of eosinophil-associated mediators (T2 CRS). SE-specific IgE was undetectable in T3 CRS and had low detectable levels (6.2%) even in T2 CRS. The CRS with nasal polyps (CRSwNP) phenotype and LM CT scores showed no significant differences between T2 and T3 CRS, while the incidence of comorbid asthma was higher in T2 CRS than T3 CRS. In T3 clusters, higher levels of neutrophilic markers were associated with disease severity and CRSwNP phenotype. Conclusions: In Koreans, there is a distinct T3 CRS endotype showing a high proportion of CRSwNP and severe disease extent, along with T2 CRS.

This study was surveyed to know utilization of the in graveyard the military and the police(MP), the catholic graveyard(CG) and graveyard of mausoleum(GM). The items of investigation were the ratio, kinds of flower, color of cut flower and form of offering a bunch of flowers. The time of investigation were New Year's day, Chusok(the korean thanksgiving day) and a weekday. On a week day, the ratio of offering a bunch of flowers was 6.3 perrcent in GM. CG and GM were 2 and 6 percent, respectively, On Chusok MP was 9 percent, CG was 25 percent and GM was 55.9 percent. On New Year's Day MP was 17.9 percent, CG was 43.3 percent and GM was 49.8 percent. Except for GM, when we compared the chusok with a week day, they were offered 12-24 times. Of the kinds of cut flower offered a bunch of flowers, chrysanthemum was 60 percent or more without regard to MP, CG and GM. About color of cut flower, white was 39.2 percent or more and yellow was 8.8 percent or more. Most of used colors were white and yellow. And they were 48 percent or more. That of on a week day was low remarkably. The form of offered flower on a graveyard were various: a flower, a basket of flower, a potflower, a flower in a case of glass, and a flower in a vase. Of that, a bunch of flowers were 33 percent or more in GC, MP and CG. KEY WORDS : flower, graveyard, new year's day, chusok, chrysanthemum

Background: The prevalence of atopic dermatitis (AD) has increased over a recent 10-year. AD tends to run in families that passed down from generation to generation and commonly starts in childhood. It is as high as 20% in children less than 5 years old. Thus, early discovery and therapy of AD are important. It has emerged the necessity of biomarker for early detection of AD. Objectives: The goal of this study is to find novel gene markers for diagnosis of early-onset atopic dermatitis in Koreans. Methods: Peripheral blood was obtained from three families (6 early-onset AD patients and 6 controls) with autosomal dominant condition. Whole Exome Sequencing (WES) was performed using SureSelect Human All Exon V4+UTR 71 Mb. Variants of atopic dermatitis were filtered step by step to gain the important candidate genes. Results: We have confirmed overlapping genes in common variants of filter 5 in three family. 15 genes were overlapped in filter 5 and two of them reached to filter 7 can be called “rare variant”. Uniquely, COL6A6 gene appeared in all of three family. We also found variants of filaggrin, filaggrin2 and IL4R that is well-known makers of atopic dermatitis. Conclusion: We were able to detect COL6A6 gene by finding overlapping genes in rare and common variants of three family. It may become a novel gene as early-onset AD marker.

The nematicidal activity of Kaempferia galanga rhizome-derived materials (methanol extract, steam distillate, and powder) toward M. incognita second-stage juveniles (J2) was examined using residual contact toxicity and pot bioassays. In residual contact toxicity bioassays with J2, the active principles of K. galanga rhizome were identified as the phenylpropanoids ethyl cinnamate (EC, 1) and ethyl-p-methoxycinnamate (EMC, 2) by spectroscopic analysis. EC exhibited 95% and 49% mortality at 0.06 and 0.04 mg/ml toward J2, respectively, whereas EMC showed 98% and 63% mortality at 0.1 and 0.08 mg/ml. In pot tests with J2, K. galanga rhizome methanol extract gave 92% and 82% mortality at 100 and 20 mg/50g soil, respectively. Steam distillate gave 88% and 68% mortality at 85 and 42.5 mg/50g soil, respectively, whereas rhizome powder provided 83% and 62% mortality at 400 and 200 mg/50g soil. K. galanga rhizome-derived materials, particularly EC and EMC, merit further study as potential root-knot nematode control agents or leads because of their great activity as a nematicide.

The toxicity of Kaempferia galanga rhizome-derived methanol extract (RME), powder (RP) and steam distillate (RSD) to Meloidogyne incognita second-stage juveniles (J2) and eggs and their effects on Lycopersicon esculentum germination and growth were examined in vitro and in pot experiments. Results were compared with those of three nematicides. In contact+fumigant bioassays with J2, RME applied at 1, 0.5 and 0.25mg/g soil exhibited 92, 88, and 73% mortality, respectively. The lethality of RME was almost similar to that of carbofuran but lower than that of either fosthiazate or metam-sodium. RSD and RP were less active than RME. In vapor-phase mortality bioassayswith J2, the test materials were effective in closed container than in open one, indicating that mode of delivery was, in part, a result of vapor action. RME, RSD, and fosthiazate treatments resulted in 91, 100, and 95% inhibition of egg hatch at 250μg/ml and 82, 88, and 81% inhibition of egg hatch at 100μg/ml, respectively. In filter-paper bioassays with L. esculentum seed at 8.8μg/cm2, RME and RP did not cause germination inhibition, while RSD and fosthiazate treatments resulted in 84 and 13% germination inhibition. In pot tests, RME and RSD applied at 8mg/g soil reduced galling caused by M. incognita significantly and fosthiazate at 0.02mg/g soil reduced galling completely. Rhizome materials did not cause any adverse effect on growth of L. esculentum, while fosthiazate application caused significantly reduced root weight. K. galanga rhizome-derived materials, particularly methanol extract, merit further study as potential nematicides and hatching inhibitors for the control of M. incognita populations as fumigants with contact action.
