GM-CSF-deficient mice are susceptible to pulmonary group B streptococcal infection. (1/4255)

Granulocyte-macrophage colony-stimulating factor (GM-CSF) gene-targeted mice (GM-/-) cleared group B streptococcus (GBS) from the lungs more slowly than wild-type mice. Expression of GM-CSF in the respiratory epithelium of GM-/- mice improved bacterial clearance to levels greater than that in wild-type GM+/+ mice. Acute aerosolization of GM-CSF to GM+/+ mice significantly enhanced clearance of GBS at 24 hours. GBS infection was associated with increased neutrophilic infiltration in lungs of GM-/- mice, while macrophage infiltrates predominated in wild-type mice, suggesting an abnormality in macrophage clearance of bacteria in the absence of GM-CSF. While phagocytosis of GBS was unaltered, production of superoxide radicals and hydrogen peroxide was markedly deficient in macrophages from GM-/- mice. Lipid peroxidation, assessed by measuring the isoprostane 8-iso-PGF2alpha, was decreased in the lungs of GM-/- mice. GM-CSF plays an important role in GBS clearance in vivo, mediated in part by its role in enhancing superoxide and hydrogen peroxide production and bacterial killing by alveolar macrophages.  (+info)

Prolonged eosinophil accumulation in allergic lung interstitium of ICAM-2 deficient mice results in extended hyperresponsiveness. (2/4255)

ICAM-2-deficient mice exhibit prolonged accumulation of eosinophils in lung interstitium concomitant with a delayed increase in eosinophil numbers in the airway lumen during the development of allergic lung inflammation. The ICAM-2-dependent increased and prolonged accumulation of eosinophils in lung interstitium results in prolonged, heightened airway hyperresponsiveness. These findings reveal an essential role for ICAM-2 in the development of the inflammatory and respiratory components of allergic lung disease. This phenotype is caused by the lack of ICAM-2 expression on non-hematopoietic cells. ICAM-2 deficiency on endothelial cells causes reduced eosinophil transmigration in vitro. ICAM-2 is not essential for lymphocyte homing or the development of leukocytes, with the exception of megakaryocyte progenitors, which are significantly reduced.  (+info)

Hexavalent chromium responsible for lung lesions induced by intratracheal instillation of chromium fumes in rats. (3/4255)

Lung toxicity of chromium fumes (Cr fumes) was examined by a single intratracheal instillation into rats of 10.6 mg and 21.3 mg Cr fumes/kg body weight and by repeated (3 times) instillations of 10.8 mg and 21.7 mg Cr fumes/kg. The pathological changes were compared with those induced by single administrations of 3.2 mg and 19.2 mg Na2CO3 solution-insoluble fraction of Cr fumes (Cr-Fr)/kg and 20.8 mg commercially available chromium (III) oxide powder (Cr (III) oxide)/kg. Single and repeated administrations of Cr fumes suppressed growth rate in a dose-dependent manner, but administrations of Cr-Fr and Cr (III) oxide did not. A single administration of Cr fumes produced granulomas in the entire airways and alveoli with progressive fibrotic changes, as well as severe mobilization and destruction of macrophages and foamy cells. Those histopathological changes were aggravated by the repeated administration of Cr fumes. On the other hand, single administrations of Cr-Fr and Cr (III) oxide produced no remarkable histopathological changes. Cr fumes were found to be composed of 73.5% chromium (III) oxide and 26.5% chromium (VI) oxide. The primary particles of Cr fumes and Cr-Fr were similar, 0.02 micron in size (sigma g: 1.25), and Cr (III) oxide particles were 0.30 micron in size (sigma g: 1.53), measured by analytical electron microscopy (ATEM). Diffuse clusters of the primary particles in Cr fumes were identified as Cr (VI) oxide. The present results suggested that the lung toxicity of Cr fumes was mainly caused by these Cr (VI) oxide (CrO3) particles in Cr fumes.  (+info)

A new model rat with acute bronchiolitis and its application to research on the toxicology of inhaled particulate matter. (4/4255)

The aim of the present study was to establish a useful animal model that simulates humans sensitive to inhaled particulate matter (PM). We have developed a new rat model of acute bronchiolitis (Br) by exposing animals to NiCl2 (Ni) aerosols for five days. Three days following the Ni exposure, the animals developed signs of tachypnea, mucous hypersecretion, and bronchiolar inflammation which seemed to progress quickly during the fourth to fifth day. They recovered from lesions after four weeks in clean air. To assess the sensitivity of the Br rats to inhaled particles, two kinds of PM of respirable size were tested with doses similar to or a little higher to the recommended threshold limit values (TLVs) for the working environment in Japan. Titanium dioxide (TiO2 = Ti) was chosen as an inert and insoluble particles and vanadium pentoxide (V2O5 = V), as a representative soluble and toxic airborne material. The Br rats exposed to either Ti or V were compared the pathological changes in the lungs and the clearance of particles to those in normal control or Br rats kept in clean air. The following significant differences were observed in Br rats: 1. delayed recovery from pre-existing lesions or exacerbated inflammation, 2. reductions in deposition and clearance rate of inhaled particles with the progress of lesions. The present results suggest that Br rats are more susceptible to inhaled particles than control rats. Therefore, concentrations of particulate matter lower than the TLVs for Japan, which have no harmful effects on normal lungs, may not always be safe in the case of pre-existing lung inflammation.  (+info)

An animal exposure system using ultrasonic nebulizer that generates well controlled aerosols from liquids. (5/4255)

Various aerosol generators have been developed for animal inhalation experiments and the performance tests of measuring instruments and respirators. It has been, however, difficult to generate aerosols from an aqueous solution or suspension keeping the concentration and particle size distribution constant for a long time. Resolving such difficulties, the present study developed an animal exposure system that generates well-controlled and stable aerosols from liquids. The exposure system consists of an aerosol generator using ultrasonic nebulizer, a mixing chamber and an exposure chamber. The validity of this system was confirmed in the generation of NiCl2 and TiO2 aerosol from solution and suspension, respectively. The concentration levels of NiCl2 aerosol were kept at 3.2 mg/m3 and 0.89 mg/m3 for 5 hours with good coefficients of variation (CVs) of 2.5% and 1.7%, respectively. For TiO2 aerosol, the concentration levels of 1.59 mg/m3 and 0.90 mg/m3 were kept for 5 hours with small CVs of 1.3% and 2.0%, respectively. This exposure system could be sufficiently used for inhalation experiments with even high toxic aerosols such as NiCl2 because a momentary high concentration possibly affects results and an extremely stable concentration is required.  (+info)

A clearance model of inhaled man-made fibers in rat lungs. (6/4255)

A clearance model of inhaled man-made fibers (MMFs) was developed, and the calculated fiber numbers and dimensions were compared with the experimental ones using a glass fiber (GF), ceramic fiber (RF1) and two potassium octatitanate whiskers (PT1, TW). If the translocation rate by macrophages is constant and the effect of dissolution and disintegration can be ignored, the fiber number is expected to decrease exponentially with time. In the experimental study, however, the fiber number did not always decrease exponentially. In the case of RF1, the fiber number decreased almost exponentially and the diameter decreased linearly with the time. The clearance rate constant of GF during 3 to 6 months after the end of one-month exposure was greater than that during 1 to 3 months. On the contrary, the clearance rate constants of PT1 and TW during 1 to 6 months were greater than next six months. The diameter and the length of GF did not change significantly. The fiber length of PT1 tends to become longer with time although the diameter did not change significantly. Our theoretical model gives a satisfactory fit to these experimental results.  (+info)

Nitrogen dioxide formation during inhaled nitric oxide therapy. (7/4255)

BACKGROUND: Nitrogen dioxide (NO2) is a toxic by-product of inhalation therapy with nitric oxide (NO). The rate of NO2 formation during NO therapy is controversial. METHODS: The formation of NO2 was studied under dynamic flows emulating a base case NO ventilator mixture containing 80 ppm NO in a 90% oxygen matrix. The difficulty in measuring NO2 concentrations below 2 ppm accurately was overcome by the use of tunable diode laser absorption spectroscopy. RESULTS: Using a second-order model, the rate constant, k, for NO2 formation was determined to be (1.19 +/- 0.11) x 10(-11) ppm-2s-1, which is in basic agreement with evaluated data from atmospheric literature. CONCLUSIONS: Inhaled NO can be delivered safely in a well-designed, continuous flow neonatal ventilatory circuit, and NO2 formation can be calculated reliably using the rate constant and circuit dwell time.  (+info)

As-required versus regular nebulized salbutamol for the treatment of acute severe asthma. (8/4255)

Current British guidelines for the administration of beta2-agonists in acute severe asthma recommend regular nebulized therapy in hospitalized patients, followed by as-required (p.r.n.) use via hand-held devices after discharge. Since beta2-agonists do not possess anti-inflammatory activity in vivo, and are thus unlikely to influence the rate of recovery from an asthma exacerbation, it was hypothesized that patients given the short-acting beta2-agonist salbutamol on an as-required basis after admission to hospital would recover as quickly as those on regular treatment, but with potential reductions in the total dose delivered. Forty-six patients with acute severe asthma were randomly assigned to either regular prescriptions of nebulized salbutamol or to usage on a p.r.n. basis, from 24 h after hospital admission. The primary outcome measures were length of hospital stay, time to recovery, and frequency of salbutamol nebulization from 24 h after admission to discharge. Secondary outcome measures were treatment side-effects (tremor, palpitations), and patient satisfaction. Length of hospital stay was reduced in those patients allocated to p.r.n. salbutamol (geometric mean (GM) 3.7 days) versus regular salbutamol (GM 4.7 days). Time taken for peak expiratory flow to reach 75% of recent best was the same in both groups. There was a highly significant reduction in the number of times nebulized therapy was delivered to the p.r.n. group (GM 7.0, range 1-30) compared with the regular treatment group (GM 14.0, range 4-57; p=0.003; 95% confidence interval for ratio of GMs 1.29-3.09). In addition, patients reported less tremor (p=0.062) and fewer palpitations (p=0.049) in the p.r.n. group. Of the patients in the p.r.n. group who had received regular nebulized therapy on previous admissions (n=12), all preferred the p.r.n. regimen. Prescribing beta2-agonists on a p.r.n. basis from 24 h after hospital admission is associated with reduced amount of drug delivered, incidence of side-effects, and possibly length of hospital stay. This has implications for the efficient use of healthcare resources.  (+info)

This study explores the relationship between inhalation amplitude and turn management in four approximately 20 minute long spontaneous multiparty conversations in Estonian. The main focus of interest is whether inhalation amplitude is greater before turn onset than in the following inhalations within the same speaking turn. The results show that inhalations directly before turn onset are greater in amplitude than those later in the turn. The difference seems to be realized by ending the inhalation at a greater lung volume value, whereas the initial lung volume before inhalation onset remains roughly the same across a single turn. The findings suggest that the increased inhalation amplitude could function as a cue for claiming the conversational floor.. ...

A systematic review of randomised double-blind controlled trials of inhaled glucocorticosteroids in preschool children with multiple-trigger wheeze has shown significant improvements in important health outcomes, including symptoms, exacerbation rates, lung function and airway hyperresponsiveness 106. The treatment effect appears to be smaller than that seen in school-age children and adults. For example, studies of ICSs in preschool children with multiple-trigger wheeze have reported a reduction in exacerbations by ∼50% 107, 108. Compared to placebo, children using 200 μg·day−1 fluticasone exhibit a mean of 5% fewer days with symptoms 106.. The dose-response relationship of ICSs in preschool children is not entirely clear. Dose-related effects have been shown for exacerbation rate on treatment with daily ICS doses of up to 400 μg·day−1 beclometasone equivalent (or 200 μg·day−1 fluticasone) via pressurised metered-dose inhaler (pMDI) with spacer (pMDI-S) 107, without any further ...
Chronic damage to pulmonary vessels leads to pulmonary hypertension (PH). Different forms of PH are quite frequent and are associated with significant morbidity and mortality. The treatment of PH is most successful, if its cause can be identified and removed before irreversible damage to the pulmonary vascular bed occurs. For patients, in whom the elimination of the underlying cause is not possible or where the cause is unknown, the treatment is aimed at reduction of pulmonary vascular resistance and improvement of cardiac and circulatory response to pressure overload of the right ventricle. One option for the PH treatment is modification of metabolism of cyclic guanosine monophosphate (GMP), which is the second messenger of nitric oxide and induces vascular vasodilation. Cyclic GMP is degraded by phosphodiesterases (PDE 5). In the clinical part, we tested the hypothesis that acute inhibition of PDE5 by sildenafil provides more selective pulmonary vasodilation than high doses of prostaglandin E1 ...

Absorption:Fluticasone Propionate:Healthy Subjects: Fluticasone propionate acts locally in the lung; therefore, plasma levels do not predict therapeutic effect. Studies using oral dosing of labeled and unlabeled drug have demonstrated that the oral systemic bioavailability of fluticasone propionate is negligible (,1%), primarily due to incomplete absorption and presystemic metabolism in the gut and liver. In contrast, the majority of the fluticasone propionate delivered to the lung is systemically absorbed.. Following administration of ADVAIR DISKUS to healthy adult subjects, peak plasma concentrations of fluticasone propionate were achieved in 1 to 2 hours.

The combination of 2 long-acting bronchodilators, a β2-agonist (LABA), and an antimuscarinic agent (LAMA) in a single inhalation device, known as double bronchodilation,1 has changed therapeutic strategies in chronic obstructive pulmonary disease (COPD). Studies evaluating the safety and efficacy of this modality have placed it at the forefront of current COPD treatment recommendations, while inhaled corticosteroids (ICS) are reserved as an alternative combined with double bronchodilation as a second treatment step in group C exacerbators or the more severe group D patients.2 In this context, the new GOLD 2017 strategy recommends the use of ICS in patients receiving double bronchodilation who continue presenting exacerbations. Consequently, there is a need to combine various drugs and inhalation devices to combine a LABA, a LAMA and an ICS to construct the so-called triple therapy using two inhalation devices.. Before the introduction of double bronchodilation, only 2 methods of administering ...

Upon analysis, an inhalable elemental carbon mass concentration arithmetic mean of 10.6 μg/m3 (geometric mean 4.21 μg/m3) was found among workers exposed to MWCNT. The concentration equates to a deposited dose of approximately 4.07 μg/d in a human, equivalent to 2 ng/d in the mouse. For MWCNT inhalation, mice were exposed for 19 d with daily depositions of 1970 ng (equivalent to 1000 d of a human exposure; cumulative 76 yr), 197 ng (100 d; 7.6 yr), and 19.7 ng (10 d; 0.76 yr) and harvested at 0, 3, 28, and 84 d post-exposure to assess pulmonary toxicity. The high dose showed cytotoxicity and inflammation that persisted through 84 d after exposure. The middle dose had no polymorphonuclear cell influx with transient cytotoxicity. The low dose was associated with a low grade inflammatory response measured by changes in mRNA expression. Increased inflammatory proteins were present in the lavage fluid at the high and middle dose through 28 d post-exposure. Pathology, including epithelial ...

T. Praveen Kumar*1, M. Indira Vani1, D. Yamini1, P. Narayana Raju1,G. Nagarjuna Reddy1. Department of Pharmaceutics, K. L. R Pharmacy College,Paloncha, Khammam, Andhra Pradesh, India.. ABSTRACT. Pulmonary drug delivery has gained tremendous scientific interest in recent years and has progressed within the context of treatment for lung diseases. Lung is an attractive environment for bio molecules, which are highly susceptible to enzymatic degradation in the gastrointestinal tract as well as hepatic degradation. Pulmonary route is a non-invasive administration for systemic delivery of therapeutic agents (mainly peptides and proteins). Lungs provide a large absorptive surface area but extremely thin (0.1 μm †0.2 μm) absorptive mucosal membrane and good blood supply. Intra tracheal administration is a first approach in lung drug delivery in vivo. In inhalation therapy most common devices used were nebulizer, Metered dose inhaler (MDI), and Dry powder inhaler (DPI). Pulmonary drug ...

Mild and Severe Asthma May Be 2 Diseases The authors of a study reported recently in the European Respiratory Journal have concluded that severe asthma and mild asthma may be different conditions with different inflammatory processes. The study, conducted by scientists across Europe, evaluated 321 patients, 158 with mild-to-moderate asthma and 163 with severe asthma. The results of the study showed that both groups had very different levels of key chemicals in their blood. Also, whereas more men suffered from asthma, women were 4 times as likely to suffer from severe asthma. Individuals with mild-to-moderate asthma were able to control their symptoms with low doses of inhaled corticosteroids. Very few with severe asthma, however, were able to have their symptoms treated despite being treated with heavier doses of drugs. ...
