Respiratory syncytial virus (RSV) preferentially infects airway epithelial cells,which might be responsible for susceptibility to asthma; however, the underlying mechanism is not clear. This study determined the activation of lymphocytes and drift of helper T (Th) subsets induced by RSV-infected human bronchial epithelial cells (HBECs) in vitro. HBECs had(More)
A filamentous actinomycete, designated strain ZX01T, was isolated from forest soil around Kanas Lake of China. A polyphasic taxonomic study was carried out to establish the status of strain ZX01T. Chemical and morphological properties of the isolate were similar to those of species of the genus Streptomyces. Analysis of the almost complete 16S rRNA gene(More)
To seek natural products for the development of environment friendly mosquito control agents, fumigant activity of eleven essential oil compounds and the joint action of the active compounds were evaluated against Culex pipiens pallens adults. Fumigant bioassay demonstrated that carvacrol exhibited the highest fumigant activity followed by thymol and(More)
Propamidine, an aromatic diamidine compound, is widely used as an antimicrobial agent. To uncover its mechanism on pathogenetic fungi, Botrytis cinerea as an object was used to investigate effects of propamidine in this paper. The transmission electron microscope results showed that the mitochondrial membranes were collapsed after propamidine treatment,(More)
BACKGROUND Secretory leukocyte proteinase inhibitor (SLPI) is an important antileukoprotease in airway. The aim of the present study was to explore the expression of SLPI in the bronchi and lung tissues of chronic obstructive pulmonary disease (COPD) models and the regulative mechanism by transforming growth factor (TGF)beta(1)/Smads signal pathway in(More)
OBJECTIVE To investigate the possible causes of the dysfunction of adrenaline release in asthma rats and to identify the role of nerve growth factor (NGF) in this process. METHODS Thirty-two SD rats were randomly divided into four groups: control group (n = 8), asthma group (n = 8), NGF group (n = 8) and anti-NGF group (n = 8). The rats of asthma group,(More)
BACKGROUND Although asthma symptoms can be temporarily controlled, it is recommended to use effective low-risk, non-drug strategies to constitute a significant advance in asthma management. Acupuncture has been traditionally used to treat asthma; however, the evidence for the efficacy of this treatment is still lacking. Previous clinical trials of(More)
BACKGROUND A convenient animal model of primary lung cancer is compelling for investigation into the disease mechanisms and for development of therapeutic strategies. This study aims to develop a reproducible rat model for lung carcinoma by intra-pulmonary injection of 3,4-benzopyrene, and to evaluate the preventive effect of green tea on the formation of(More)
OBJECTIVE We investigate an innovative and efficacious procedure for restoring wrist flexion, finger flexion, and hand sensation by passing the contralateral C7 through a subcutaneous tunnel across the anterior surface of the chest and neck. METHODS Four patients (3 men, 1 woman) with total brachial plexus avulsion were treated from November 2005 to July(More)
BACKGROUND Adrenal neuroendocrine plays an important role in asthma. The activity of the sympathoadrenal system could be altered by early life events. The effects of maternal asthma during pregnancy on the adrenal medulla of offspring remain unknown. METHODOLOGY/PRINCIPAL FINDINGS This study aims to explore the influence of maternal asthma during(More)
