An inhalation exposure chamber, referred to as the Small Animal Inhalation Rig (SAIR) has been designed to expose test subjects to inhalation aerosols whilst minimising the amount of compound used. This inhalation chamber may be employed for acute inhalation studies with dry powder aerosols involving mice, rats or guinea pigs. This rig consists of two main parts; a fluidised bed aerosol generat...
Inhalant tobramycin is established in the treatment of cystic fibrosis patients. Conventional nebulizers require a large amount of the expensive compound, because only a small fraction is deposited in the targeted lung region. In contrast, techniques based on controlled inhalation allow a high and reproducible deposition of the drug in specific lung regions. In our study we compared the efficie...
Introduction: Labor pain is one of the most severe pains that women experience during the pregnancy period. Inhalation and foot bath are common methods that reduce the pain of labor. The purpose of this study was to compare the effects of warm foot bath with inhalation of rose essence and warm foot bath lonely on pain of labor in primiparous women. Materials and Methods: This randomized clncont...

Studies have demonstrated that heat shock protein 70 (HSP70) plays an important role in the protection of stressed organisms. The development of strategies for enhancing HSPs expression may provide novel means of minimizing inflammatory lung conditions, such as acute lung injury. This study aimed to examine the effect of L-alanyl-L-glutamine (GLN) inhalation in enhancing pulmonary HSP72 (induci...
BACKGROUND There is no systematic analysis to identify problems involved with instruction on inhalation therapy for elderly patients. We conducted a nationwide questionnaire survey for patients and medical professionals. METHODS A questionnaire survey was conducted of adult patients on inhaled drugs (ages 18-92 years, 820 individuals) and medical professionals (pharmacists or nurses) who prov...
Asthma and chronic obstructive pulmonary disease (COPD) patients are required to inhale forcefully and deeply to receive medication when using a dry powder inhaler (DPI). There is a clinical need to objectively monitor the inhalation flow profile of DPIs in order to remotely monitor patient inhalation technique. Audio-based methods have been previously employed to accurately estimate flow param...
We investigated the effects of fragrance inhalation on sympathetic activity in normal adult subjects using both power spectral analysis of blood pressure fluctuations and measurement of plasma catecholamine levels. Fragrance inhalation of essential oils, such as pepper oil, estragon oil, fennel oil or grapefruit oil, resulted in 1.5- to 2.5-fold increase in relative sympathetic activity, repres...
We have compared the effects of inhalation of aerosolized surfactant on experimental acute respiratory distress syndrome. Escherichia coli endotoxin (55 (SD 20) mg kg(-1)) was injected into the tracheas of 36 adult rats anaesthetized and mechanically ventilated with pure oxygen. When the Pa(O(2)) decreased to 11.3 (3.3) kPa, the animals were randomly subjected to inhalation of aerosolized modif...
The Relation Between Cardiac Function and Cerebral Blood Flow in Stroke Patients. 1. Effect of CO, Inhalation • The effects of CO2 inhalation were determined on 23 stroke patients with and without hypertension who underwent clinical, cardiohemodynamic, cerebral blood flow (hemispheric mean and regional), cerebral metabolic rate and cerebral angiographical studies. Cardiac output, heart rate, sy...
