Spherical monodisperse ferromagnetic iron oxide particles of 1.9-microm geometric and 4.2-microm aerodynamic diameter were inhaled by 13 healthy nonsmoking subjects using the shallow bolus technique. The bolus width was 100 ml, and the penetration front depth was 150 +/- 27 ml. The mean flow rate during inhalation and exhalation was 250 ml/s. The Fowler dead space and the phase 1 dead space of the airways were 282 +/- 49 and 164 +/- 34 ml, respectively. Deposition was below 20% without breath…

Mucociliary and long-term particle clearance in airways of patients with immotile cilia

Despite non-functioning cilia the effectiveness of airway clearance in PCD patients is comparable to healthy NS, with a prolonged kinetics of one week, which may primarily reflect the effective of cough clearance.

PARTICLE CLEARANCE FROM THE AIRWAYS OF SUBJECTS WITH BRONCHIAL HYPERRESPONSIVENESS AND WITH CHRONIC OBSTRUCTIVE PULMONARY DISEASE

Long-term particle retention in the airways has to be taken into account in aerosol toxicology risk assessment and aerosol therapy dose evaluation.

Influence of particle size and material properties on mucociliary clearance from the airways.

Investigation of the effect of particle size, zeta-potential, and mucoadhesive particle properties on mucociliary particle clearance finds a promising strategy to improve inhalation therapy by prolonged particle/drug residence time within the airways.

Long-term clearance from small airways in subjects with ciliary dysfunction

This study shows that despite ciliary dysfunction, clearance continues in the small airways beyond 24 h, suggesting there are apparently additional clearance mechanisms present in theSmall airways.

EFFECT OF PARTICLE SIZE ON SLOW PARTICLE CLEARANCE FROM THE BRONCHIAL TREE

The Human Respiratory Tract Model of the International Commission on Radiological Protection assumes that a fraction of particles deposited in the bronchial tree clears slowly, this fraction decreasing with increasing particle geometric diameter, and volunteers inhaled polystyrene and gold particles simultaneously, as a 'bolus' at the end of each breath to minimize alveolar deposition.

Deposition, retention, and translocation of ultrafine particles from the central airways and lung periphery.

Within the limits of detection of the experimental system, most inhaled ultrafine carbon particles are retained in the lung periphery and in the conducting airways without substantial systemic translocation or accumulation in the liver at 48 hours.

Results of the simulations clearly demonstrate that for the specific deposition scenario (sitting, nasal breathing) considered here fast clearance fraction exhibits a slight decrease with increasing age, but total clearance times are rather constant among the age groups.

In vivo particle uptake by airway macrophages in healthy volunteers.

The data suggest that airway surface macrophages in healthy subjects rapidly engulf insoluble particles in vivo and macrophage recruitment and phagocytosis-modifying agents are factors in vivo that likely affect particle uptake and its time course.

Long-term clearance from small airways decreases with age

Small airway clearance over 21 days was found to decrease with age, which might be one factor associated with the high prevalence of respiratory symptoms associated among the elderly.

Assessment of long-term bronchiolar clearance of particles from measurements of lung retention and theoretical estimates of regional deposition.

The experimental data and the predictions of the deposition models indicate that about 40% of the particles deposited in the conducting airways during the slow inhalation were retained after 24 hours and strongly indicate that the particles which cleared with a half-time of about 4 days were mainly depositing in the bronchiolar region.

Comparison of clearance of particles inhaled with bolus and extremely slow inhalation techniques.

Both the experimental and theoretical data indicate that the shallow bolus particles to a considerable extent reach both the bb and the alveolar regions and that they do that at about the same extent as the particles inhaled extremely slow.

Human alveolar long-term clearance of ferromagnetic iron oxide microparticles in healthy and diseased subjects.

It is concluded that the lung clearance measured with iron oxide tracer particles primarily reflects clearance by intraphagosomal particle dissolution within alveolar macrophages, which is impaired by cigarette smoke consumption and in patients.

Clearance of particles from small ciliated airways.

The results strongly indicate that a considerable fraction of particles deposited in small ciliated airways had not cleared within 24 h, and that these particles cleared differently from particles deposit in the alveolar region, and the experimental data agree quite well with the IRTM predictions made using its default slow clearance fractions.

Bronchial airway deposition and retention of particles in inhaled boluses: effect of anatomic dead space.

Analysis of central-to-peripheral ratios of initial deposition and 24-h-retention gamma-camera images suggest significant retention of insoluble particles in large bronchial airways at 24 h postdeposition, which may prove useful for designing aerosol delivery techniques to target bronchia and understanding airway retention of inhaled particles.

Anatomic localization of 24- and 96-h particle retention in canine airways.

The anatomic location of retained particles after shallow bolus inhalation was determined in anesthetized, ventilated beagle dogs, suggesting that long-term retention in airways is at the bronchiolar level.

Retention of Teflon particles in hamster lungs: a stereological study.

This study with highly hydrophobic Teflon particles clearly demonstrates that for spheres of this size, surface tension and line tension forces rather than the particles' surface free energy are decisive for the displacement of particles into the aqueous phase by surfactant.

Regional deposition and retention of particles in shallow, inhaled boluses: effect of lung volume.

Asymmetric bolus ventilation for these very shallow boluses does not lead to significant increases in peripheral alveolar deposition, and data may prove useful for designing aerosol delivery techniques to target bronchial airways and understanding airway retention of inhaled particles.

[Particle retention in the intrapulmonary conducting airways in hamsters].

Surfactant is important for the retention of particles in the intrapulmonary conducting airways of hamsters and there is evidence for the existence of a resident population of very active airway macrophages which play a pivotal role in clearance of the retained particles.

Surfactant and inhaled particles in the conducting airways: Structural, stereological, and biophysical aspects

The combination of structural and stereological analyses with in vitro and in vivo measurements has led to new insights into the role of airway surfactant with respect to the fate of inhaled particles, which may have important consequences regarding the effects of hazardous particles.
