Berries and branches essential oil of Juniperus phoenicea were obtained by electromagnetic induction heating assisted extraction and by hydrodistillation with a yield varied from (1.2 ± 0.3 to 2.4 ± 0.7%) and from (0.6 ± 0.1% to 1.1 ± 0.1%), respectively. forty eight compounds were identified representing (97.2 – 99.7%) of the oil. α-Pinene (40.3 – 67.8%) and δ-3-carene (13.5 – 26.8%) were the main compounds in berries and branches essential oils. Antioxidant activity was evaluated by three means: inhibition of 2, 2-diphenyl-1-picryl hydrazyl (DPPH) free radical, reducing power and β-Carotene/linoleic acid bleaching. The antioxidant activity of essential oils showed IC₅₀ ranging from 67.6 ± 1.02 µg/mL to 131.5 ± 0.8 µg/mL for berries and from 98 ± 1.25 µg/mL to 166.8 ± 0.29 µg/mL for the branches. Berries oil show more potent antioxidant activity compared to branches. This result is supported by the three methods investigated in this work.

Lithium, first used by Cade in 1949 for the treatment of mania, is now commonly used in several affective disorders. The precise mechanism of its action is not clearly understood but the side effects may be severe. Prolongation of succinylcholine and pancuronium which possible mechanism of interaction involves impaired acetylcholine synthesis and release at nerve terminal has been reported. The present report describes a case of prolonged neuromuscular blockade induced by succinylcholine in a manic depressive patient being treated with oral lithium carbonate.

Objective: To investigate the sensitization characteristics of Juniperus chinensis pollen in patients with allergic rhinitis and/or allergic asthma in Beijing area, and to explore the characteristics of Juniper chinensis pollen sensitized population. Methods: Patients with suspected allergic rhinitis and/or asthma from January 2017 to December 2019 in the outpatient department of Allergy Department of Beijing Shijitan Hospital were selected in this study. Skin prick test (SPT) was performed with Juniper chinensis pollen allergen reagent to compare different age and disease allergen distribution, and to observe the sensitization characteristics of its population. All of the analyses were performed using SAS software version 9.4. Results: A total of 8 380 patients were enrolled in the end. The total positive rate of Juniper chinensis pollen SPT reached 49.92% (4 183/8 380). The positive rate of Juniper chinensis pollen SPT was highest in the 10-14 age group, reaching 60.99% (283/464). Compared with other age groups, there was a statistical difference (χ²=266.77, P<0.01). The SPT positive rate of patients aged less than 10 years increased with the increase of age, while the SPT positive rate of patients aged over 40 years decreased with the increase of age. Single Juniper chinensis pollen was less allergenic, accounting for about 25.05% (1 048/4 183), and the patients' age was (35.21±12.39) years. Regardless of single Juniper chinensis pollen or other pollen allergies, allergic rhinitis was the main disease. Among the patients with SPT positive Juniper chinensis pollen combined with other inhaled pollen allergens, willow pollen accounted for the first (74.99%). The positive rate of Juniper chinensis pollen was the highest in patients with single allergic rhinitis, accounting for 52.05% (3 797/7 295), and the rate in patients with single allergic asthma was the lowest, accounting for 17.49% (53/303), with statistically difference (χ²=138.99, P<0.01). Conclusions: Juniper chinensis pollen is highly sensitized in patients with allergic rhinitis and/or allergic asthma in Beijing . The positive rate of SPT is highest among 10-14 age group, most of which showed strong positive reaction, and allergic rhinitis is more common in Juniper chinensis pollen sensitization diseases.

Omalizumab is frequently used as add-on treatment to inhaled corticosteroids (ICS) and long-acting β2-agonists in patients with suboptimal control of severe asthma. Patients with severe asthma will typically require chronic treatment, although due to the limited amount of data available there are still some concerns about the safety and efficacy of long-term therapy with omalizumab. Herein, in an extension of a previous 4-year study, we report disease-related outcomes of 8 patients with severe persistent allergic asthma who have been followed for a total of 9 years in a real-life setting. Both quality of life (QoL) (evaluated using the Juniper Asthma-Related QoL Questionnaire [AQLQ]) and forced expiratory volume in 1 second (FEV1) showed sustained improvement at 9 years. The median values of AQLQ and FEV1 at 4 years were 5.5 and 82.0% compared to 5.9 and 85.5%, respectively, at 9 years, which were all significantly increased from baseline. After 9 years, the mean annual number of severe exacerbations was 0.63 compared to 5 at baseline. There also appeared to be a trend toward use of a lower dose of ICS at longer follow-up times. After 9 years, there were no safety concerns for continued use of omalizumab, and no asthma-related hospitalizations or emergency department visits were documented over the last 5 years. The present analysis is the longest reported clinical follow-up of omalizumab. Long-term maintenance treatment with omalizumab for up to 9 years is associated with continued benefits in reducing symptoms, exacerbations, and medication burden without any safety concerns.

PURPOSE: Airborne pollen is the most common causative agents of allergic disease. Since 2000, there isn't no more report about airborne pollen in Busan. This study is that pollen in one area of Busan was collected to investigate species, particle counts, seasonal distribution, and of its correlation with reactivity to skin prick test in children during 1998-2012. METHODS: Rotorod sampler was installed on the rooftop of St. Mary Hospital in Busan. A 24-hour sampling of airborne allergens over a fifteen-year period was conducted 6 days/wk from January 1, 1998 to December 31, 2012. After staining they were identified, counted and recorded with the weather in Busan. RESULTS: Major pollens collected were Pine, Alder, Oak, Juniperus, Humulus. The pollen season is relatively short and the pollen dispersed mainly during the period from March to May in case of tree pollen, from April to September in case of grass pollen and from August to October in case of weed pollen. Total annual pollen count ranged from 36,412 grains/m3 (2002) to 1,342 grains/m3 (2006). The peak pollen season was seen for spring and autumn, especially in May and September during 1998-2012. In skin prick tests, birch was the highest sensitization rate (15.1%), followed by alder (14.7%), hazel (14.1%) in the tree for 15 years. And in weed, mugwort and ragweed were the highest sensitization rate (10.6%, 10.3%), followed by humulus (5.5%) for 15 years, but since 2008, was increased. CONCLUSION: Analysis of pollens sampled in the atmosphere of Busan, Korea, for a 15-year period identified 24 species of pollens with seasonal variation of some clinically important pollen load. Analysis of data, it showed that alder and birch are main allergen in spring for 15 years, and in 1998-2008, ragweed and artemisia was main allergen in fall, since 2009, followed by humulus.

BACKGROUND: The effectiveness of treatment of asthma has been assessed by lung function test, airway responsiveness and symptoms. But, they rarely capture the emotional and social impairment. Recently, questionnaires that reflect the quality of life (QOL) in asthma patients were developed. In this study, we evaluated the impairment on quality of life in Korean adult asthmatic patients cross-sectionally by using the QOL questionnaires of Juniper EF. METHODS: One hundred eighty nine adult patients with over 1 year history of asthma were enrolled. The patients were asked to choose the five most important daily activities among 40 daily activities which were important in Korea. The QOL questionnaire was composed of 32 items in 4 domains (activity, symptom, emotion and exposure to environmental stimuli) and the response option was scored on a 7-point scale. RESULTS: 45.5% of patients who participated in this study were men, and 48.3% had atopy. The disease severities of asthma evaluated by physician were mild intermittent (31%), mild persistent (35%), moderate persistent (21%) and severe persistent (12%). Among 40 items of general daily activities, 19 items were chosen by more than 20 patients. Among them, running, walking uphills, hurried movement were most impaired daily activities. The QOL of our asthma patients showed statistical difference on disease severity, control state and symptom status during the last 3 months. The QOL was not influenced by sex, age or atopy score. Occupational asthma showed the lowest score on QOL in all 4 domains. On grouping with medications, the group with oral steroid noted statistically lower scores of QOL in all domains. The QOL score of asthma was well correlated with average symptom attacks during the last 3 months. CONCLUSION: According to our study, rapid control of asthma and lowering of the diseaseseverity are essential for improvement of QOL. A QOL questionnaire in Korea should be ... (continue)

OBJECTIVES: Tree pollen causes allergic rhinitis and asthma. We investigated children who diagnosed as rhinitis or asthma, living in Busan, for tree allergen sensitization, component allergen, oral allergy syndrome, and the relationship between pollen counts and allergen sensitization.METHODS: Pollen were collected in Busan, from January 1 to December 31, 2017, using a Rotorod sampler and enumerated using a microscope. We conducted a study of children with rhinitis or asthma at Busan St. Mary's Hospital in 2017, administered an ISAAC questionnaire, and an oral allergy syndrome survey. Serum specific Ig E tests were performed.RESULTS: Among the 57 patients, the mean age was 9.3 years. The pollen counts in decreasing order were as follows: pine, alder, oak, juniper, beech, ginkgo, and birch. For sensitization, birch and alder 35.1%, Japanese cedar 19.3%, juniper 17.5%, pine 10.5%, and Japanese cypress 8.2%. The component Ig E was tested in 27 patients. Bet v 1 had a high correlation with birch, alder, and peach. Bet v 2 showed a statistically significant correlation with all tree pollen except cypress. Bet v 4 did not have any apparent correlation. Bet v 6 had the same pattern as Bet v 2, but correlation coefficient was higher than that of Bet v 2. Oral allergy syndrome was noted in 7 patients, including peach, peanut, apple, tomato, kiwi, and sesame.CONCLUSIONS: Alder and juniper are clinically important tree pollens in Busan. These pollens cause sensitization to birch and Japanese cedar by cross-reaction.

PURPOSE: Airborne pollen and mold spores are common causative agents of allergic disease. Atmospheric pollen and spores in one area of Pusan were collected to investigate species, particle amount, seasonal distribution, and of its association with reactivity to skin prick test in children. METHODS: Rotorod sampler was installed on the rooftop of St. Benedict Hospital in Pusan. 24 hour sampling of airborne allergens over a two year period was conducted 6 days/week from July 1, 1997 to June 30, 1999. Those samples were stained with Calberla's fuchsin and were identified, counted under the light microscope (400xfor pollen, 1000xfor mold). The data were compared with the daily weather report and allergy skin test. RESULTS: Major pollens collected were Pinus, Alnus, Juniperus, Betula, Quercus, Artemisia, Ambrosia, and Chenospodium-Amaranthus. The pollen season is relatively short and the pollen dispersed mainly during the period from March to May in case of tree pollen and from August to October in case of grass pollen. Total pollen count ranged from 0 to 1000 grains/m3/day (May 14, 99). The peak pollen season was seen during Spring and Autumn, especially in March and September. Major mold spores counted were Cladosporium, Leptospheria and Alternaria. Mold spore count ranged from 0 to 2,360 spores/m3/day (Oct. 8, 98). Cladosporium was dispersed year-round, but mainly in the October and November, while Leptospheria was dispersed mainly in the period from July to September and Alternaria counts tended to be higher around July. The concentration of mold is roughly correlated with the amount of rainfall, having high spore count in July and August, especially in case of Leptospheria. In terms of positive reaction to skin prick test in children, Alnus and Artemisia were found to be allergen source in early spring and late summer season, respectively. CONCLUSION: Analysis of pollens and mold spores sampled in the atmosphere of Pusan, Korea, for a 2 year period identified 19 species of pollens and 22 species of mold spores with seasonal variation of some clinically important pollen/mold load. Cladosporium, Leptospheria and Alternaria are found to be three major molds, especially from June to October.
