IL-22 has similarities with IL-10 including conserved sequences with IL-10. IL-22 receptor is also comprised of two chains known as L-22R1 and L-10R2; supporting the speculation that the two cytokines may have similar effects. The aim of this study was to shed some light on the biological activity of IL-22 upon the cord blood CD4+CD25- T cells. In this research, cord blood T CD4+CD25- cells were cultured in presence of anti CD2/CD3/CD28 coated beads, IL-2 and IL-22 for two weeks at 37 oC and 5% CO2. Flow cytometry analysis showed that IL-22 has no effect upon CD25 and Foxp3 expression. Also, the results indicated that IL-22 is not involved in CD4+ T cell proliferation. Moreover, the results of suppression assay did not show any suppression effect on the cultured T cells. Thus, it seems that umbilical cord blood T cells probably do not express IL-22R1 on their surface. https://ijaai.tums.ac.ir/index.php/ijaai/article/view/270 https://ijaai.tums.ac.ir/index.php/ijaai/article/download/270/270

Interleukin-15(IL-15) is an immunoregulatory cytokine, known to enhance cytolytic function of cord Natural Killer (NK) cells. The aim of this study was to investigate the effect of IL-15 on NK cytotoxicity simultaneously in different cell death stages. We compared the ability of IL-15 to enhance the NK cytotoxicity of CB in comparison to adult blood Mononuclear Cells (MNCs) against K562 target cells by co-staining with AnnexinV-FITC and Propidium Iodide after 3.5 h incubation at 37C and 5% CO2 by using flow cytometric method. We also evaluated phenotypic changes after treatment by IL-15 in both cell sources. Our results indicated that CB samples had lower level of apoptosis, while necrosis was negligible; also by escalating Effector: Target (E: T), we got higher level of apoptosis and necrosis in peripheral blood (PB). NK activity of cord and adult MNCs was enhanced by incubation with IL-15 (10 ng/ml) for 72 h with significantly higher results of PB in comparison to CB (p https://ijaai.tums.ac.ir/index.php/ijaai/article/view/271 https://ijaai.tums.ac.ir/index.php/ijaai/article/download/271/271

We designed this study to evaluate relation between Transforming Growth Factor β1 (TGFβ1) and Tissue Inhibitory of Metaloproteinase 2 (TIMP2) as two main tissue mediators on activity and reversibility of asthma and chronic obstructive pulmonary disease (COPD). In a cross sectional study we evaluated TIMP2 and TGFβ1 expression in two groups of 29 asthmatic (14 males and 15 females) and 13 male COPD patients using semi-quantitative PCR on induced sputum samples. The relation between TIMP2 and TGFβ1 and PFT indices and disease free period were assessed. The COPD patients with raised expression of both TGFβ1 and TIMP2 had better pulmonary function test (PFT) indices and also longer disease free period. In contrast patients with chronic asthma could remain in well pulmonary function status with raised TIMP2 and decreased TGFβ1 expression. We supposed that underlying inflammatory process is the main reason for the different effect of cytokines in asthma and COPD. It raises concern about critical role of corticosteroids consumption on various cytokines expression. Furthermore TGFβ1 may be served as a biomarker in sputum for assessing disease activity and evidence based prescribing corticosteroids in patients with COPD and asthma. https://ijaai.tums.ac.ir/index.php/ijaai/article/view/272 https://ijaai.tums.ac.ir/index.php/ijaai/article/download/272/272

The aim of the present study is to identify the allergenic properties of A. retroflexus pollen. Sixteen patients with allergy to A. retroflexus pollen were selected for the study. The antigenic and allergenic profiles of the A. retroflexus pollen extract as well as pollen extracts from other species of the Amaranthaceae/Chenopodiaceae family, including Chenopodium album, Kochia scoparia, and Salsola kali, were evaluated by ELISA, immunoblotting, and immunoblot inhibition assays. The resolved protein fractions on SDS-PAGE ranged from 10-85 kDa. Several allergenic components (MW 85, 45, 39, 18, 15, and 10 kDa) of the A. retroflexus pollen extract were recognized by using patients' sera by specific antibody of IgE class using ELISA and immunoblot assays. The IgE reactivity of the A. retroflexus pollen extract was partially inhibited by all three pollen extracts tested. the inhibition by the S. kali pollen extract was more than those by other pollen extracts. Moreover, the wheal diameters by the A. retroflexus pollen extract were highly correlated with those by C. album, K. scoparia and S. kali pollen extracts. In conclusion, three proteins with apparent MWs of 39, 45, and 66 kDa are suggested as the common allergenic components among the four pollens from the Amaranthaceae/Chenopodiaceae family. It appears that there are some common (similar) epitopes among the four common allergenic pollens. https://ijaai.tums.ac.ir/index.php/ijaai/article/view/273 https://ijaai.tums.ac.ir/index.php/ijaai/article/download/273/273

Eighty one children were recruited from the Hospital University Center of Fez. All of them had completed a questionnaire before taking sera. The sera were used to measure total IgE and specific data to proteins of egg's white (EWP), peanuts (PP) and gliadins (G). In last part, we studied the reactivity of specific IgE to native and to heat- and acid-treated allergens. Allergen-specific IgE measurement indicated more positive values for gliadins (46.9% up to 2IU/ml) than egg white's (29.6%) and peanut's proteins (22.2%). According to predictive values published by Sampson (2001), 14.3% of children are sensitive to egg white's proteins, 4.1% to gliadins and 2.7% to peanut's proteins. The allergenic potential of EWP and gliadins among children were partially diminished by heat and acid treatment. Allergen-specific IgE measurement indicates that children from Fez region are more sensitive to EWP than peanut's proteins and gliadins. Treatments of these food proteins indicated that recognition by children IgE can be reduced by thermal or acid treatment of these allergens. https://ijaai.tums.ac.ir/index.php/ijaai/article/view/274 https://ijaai.tums.ac.ir/index.php/ijaai/article/download/274/274

We studied effects of N-acetylcysteine (NAC) as a mucolytic and antioxidant agent in asthma exacerbation. In this randomized, single-blinded, placebo-controlled study 50 patients ( 17 male, 33 female, mean age 48.94±13.68) with asthma exacerbation were randomized to receive either oral 600 mg b.d. N-acetylcystiene or placebo in addition to standard treatment during 5 days hospitalization. Daily measurements of wheezing, dyspnea, cough, sputum, expectoration, night sleep scores and morning PEFR were performed. There was no significant difference in wheezing score between patients assigned NAC and those assigned placebo in day 5(0.84[SD 0.94] VS 0.87[SD 0.79]) and also in cough score (0.72[SD 0.84] VS 0.79[SD 0.97]), dyspnea score (0.84[SD 1.06] VS 0.91[SD 1.01]), sputum score(0.79[SD 0.83] VS 0.62[SD 0.71]), expectoration score(0.79[SD 0.97] VS 0.83[SD 1.09]), night sleep score(1[SD 1.17] VS 0.67[SD 0.98] and morning PEFR (256[SD 96.36] VS 282[SD 98.86]). We concluded that addition of N-acetylcysteine to usual asthma medication has no significant effect in treatment of asthma exacerbation. https://ijaai.tums.ac.ir/index.php/ijaai/article/view/275 https://ijaai.tums.ac.ir/index.php/ijaai/article/download/275/275

The validity and predictability of revised Jones Morbidity Index (JMI) as a simple and practical tool for asthma evaluation morbidity has not yet been tested in Iran. This study aimed to evaluate the predictability and validity of a revised JMI in northern Iran. As a one-year follow up study, 210 adult asthmatic patients were visited in an asthma clinic in the town of Babol (north of Iran) at two stages. At first stage, in addition to demographic information, 3 simple questions of revised JMI were asked and Pulmonary Expiratory Flow Rate (PEFR) for each patient was measured. Based on modified JMI, patients were categorized in three groups: Low, Medium, and High morbidity. At the second stage, after one year, patients were visited again and in addition to their last year medical records, the same questionnaires were filled. The validity of the index checked by PEFR values at two stages and its predictability was evaluated by morbidity factors during the last year. From hundred and seventy (170) patients who were able to fulfil the second stage of the study, 55 patients (32%) had been categorized as low, 88 patients (52%) as medium, and 27 patients (16%) as high morbidity. The percentages of patients PEFR to the estimated normal values in these three categories (90.8%, 74.7%, and 55.3% respectively) were significantly different which shows a good correlation between PEFR values and asthma morbidity (p https://ijaai.tums.ac.ir/index.php/ijaai/article/view/276 https://ijaai.tums.ac.ir/index.php/ijaai/article/download/276/276

Griffiths School of Mathematics and Applied Statistics, University of Wollongong, Wollongong, Australia 2015 10 01 Airway mucus hypersecretion Health effects caused by air pollutants may range from subtle biochemical or physiological signs, such as mildly reduced lung function, to difficult breathing, wheezing, coughing and exacerbation of existing respiratory conditions such as asthma. The aim of this study was measuring the adverse health effects of air pollution on lung function of primary school students. The lung function of students was measured daily for seven weeks in two elementary schools in District 12 of Tehran, after obtaining permission from the two principals and signed parents' consent forms. Twenty four hourly air pollution levels were used as potential predictors of lung function. The principal analysis conducted was a logistic regression on a subset of the data using a case-crossover design. The outcomes data consisted of the results of lung function tests for 356 female and 206 male students over the six-week period. Using the difference between mean (87) and maximum (125) concentration of moving average of NO in this period to judge the size of the effect, such an increase in NO is predicted to lead to an increase in the probability of poor lung function (OR=20) based on population-based predicted value. This study has shown strong and consistent associations between children's poor lung function and outdoor air pollutants in District 12 of Tehran for some pollutants. The strong association found in this study was an increase in seven-day moving average of NO using both definitions. https://ijaai.tums.ac.ir/index.php/ijaai/article/view/277 https://ijaai.tums.ac.ir/index.php/ijaai/article/download/277/277
