This study is aimed at developing a novel analytical method to identify optimal inhalation flow patterns for commercial dry powder inhalers (DPIs) and pressurized metered dose inhalers (pMDIs). As typical commercial DPI and pMDI, Pulmicort® Turbuhaler® and Sultanol® Inhaler were evaluated by an in-vitro inhalation performance testing system with a flow pattern simulator. An 8-stage Andersen cascade impactor (ACI) or twin stage liquid impinger (TSLI) was applied to determine the inhalation performance. The peak flow rate (PFR) of the inhalation flow pattern was set from 15 to 80 L/min in reference to our previous study...

An optimum carrier rugosity is essential to achieve a satisfying drug deposition efficiency for the carrier based dry powder inhalation (DPI). Therefore, a non-organic spray drying technique was firstly used to prepare nanoporous mannitol with small asperities to enhance the DPI aerosolization performance. Ammonium carbonate was used as a pore-forming agent since it decomposed with volatile during preparation. It was found that only the porous structure, and hence the specific surface area and carrier density were changed at different ammonium carbonate concentration...

Diffuse alveolar injury, edema, and inflammation are fundamental signs of acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). Whereas the systemic administration of corticosteroids previously led to controversial results, this study evaluated if corticosteroids given intratracheally may improve lung functions and reduce edema formation, migration of cells into the lung and their activation in experimentally-induced ALI. In oxygen-ventilated rabbits, ALI was induced by repetitive saline lung lavage, until PaO2 decreased to < 26...

Meconium aspiration syndrome (MAS) triggers inflammatory and oxidative pathways which can inactivate both pulmonary surfactant and therapeutically given exogenous surfactant. Glucocorticoid budesonide added to exogenous surfactant can inhibit inflammation and thereby enhance treatment efficacy. Neonatal meconium (25 mg/ml, 4 ml/kg) was administered intratracheally (i.t.) to rabbits. When the MAS model was prepared, animals were treated with budesonide i.t. (Pulmicort, 0.25 mg/kg, M+B); with surfactant lung lavage (Curosurf®, 10 ml/kg, 5 mg phospholipids/ml, M+S) followed by undiluted Curosurf® i...

BACKGROUND: Pulmonary rehabilitation (PR) is proposed as an effective strategy to decrease surgical morbidity. However, appropriate rehabilitation plan, initiation time, and optimal duration of PR remain unclear. Lung cancer patients with chronic obstructive pulmonary disease (COPD) are considered high-risk population for postoperative pulmonary complications (PPCs) because of poor lung fitness and cardiopulmonary endurance. This study aims to assess the impact of a one-week, systematic and highly-intensive rehabilitation on surgical lung cancer patients with mild to moderate COPD...

Meconium aspiration syndrome (MAS) is a serious condition, which can be treated with exogenous surfactant and mechanical ventilation. However, meconium-induced inflammation, lung edema and oxidative damage may inactivate delivered surfactant and thereby reduce effectiveness of the therapy. As we presumed that addition of anti-inflammatory agent into the surfactant may alleviate inflammation and enhance efficiency of the therapy, this study was performed to evaluate effects of surfactant therapy enriched with budesonide versus surfactant-only therapy on markers of oxidative stress in experimental model of MAS...
