Nitrofurantoin is indicated for the treatment or prophylaxis of uncomplicated urinary tract infections. Currently, it is considered as second-line treatment for this type of infection because of emerging bacterial resistance. Nitrofurantoin is bioactivated to various reactive intermediates that interfere with bacterial ribosomal proteins and inhibit the synthesis of critical cellular macromolec...
Pseudomonas aeruginosa is an opportunistic bacterial pathogen responsible for a high incidence of acute and chronic pulmonary infection. These infections are particularly prevalent in patients with chronic obstructive pulmonary disease and cystic fibrosis: much of the morbidity and pathophysiology associated with these diseases is due to a hypersusceptibility to bacterial infection. Innate immu...
The adipocyte-derived hormone leptin is an important regulator of appetite and energy expenditure and is now appreciated for its ability to control innate and adaptive immune responses. We have reported previously that the leptin-deficient ob/ob mouse exhibited increased susceptibility to the Gram-negative bacterium Klebsiella pneumoniae. In this report we assessed the impact of chronic leptin ...
High-frequency chest compressions (HFCC) have been suggested as an alternative to conventional chest physiotherapy to aid sputum clearance in patients with cystic fibrosis (CF). We aimed to compare the active cycle of breathing techniques (ACBT) with the Hayek Oscillator Cuirass, performing HFCC on secretion clearance in children with CF during an exacerbation. Ten children (7 males; median age...
Eight patients with Young's syndrome were treated with four "mucoregulatory" agents for eight weeks in a randomised, open crossover study. There was no improvement in tracheobronchial clearance, pulmonary function, or sperm count.
Introduction : Chronic obstructive pulmonary disease (COPD) is a condition in which the lungs experience obstruction that not fully reversible. One of independent nursing interventions dealing with decreased diaphragmatic breathing exersice relaxation technique. This technique non-pharmacological therapy can improve abdominal movement by reducing respiratory muscle activity. The purpose study w...
Successful host defense against numerous pulmonary infections depends on bacterial clearance by polymorphonuclear leukocytes (PMNs); however, excessive PMN accumulation can result in life-threatening lung injury. Local expression of CXC chemokines is critical for PMN recruitment. The impact of chemokine-dependent PMN recruitment during pulmonary Mycobacterium tuberculosis infection is not fully...
Leptospirosis is a public health problem worldwide. Severe leptospirosis manifests as pulmonary edema leading to acute respiratory distress syndrome and polyuric acute renal failure (ARF). The etiology of leptospirosis-induced pulmonary edema is unclear. Lung edema clearance is largely affected by active sodium transport out of the alveoli rather than by reversal of the Starling forces. The obj...
Introduction: The use of pulmonary drug delivery as a non-invasive drug delivery system for the systemic treatment of diseases as well as the topical treatment of respiratory diseases is increasing. Among the various inhaled formulations, inhaled dry powders show advantages over the other forms of inhaled medicines due to high stability, bioavailability and ease of use. The effect of particle p...
The importance of endogenous interleukin 1 (IL-1) in resistance to Pneumocystis carinii infection was examined in a SCID mouse model. Naturally acquired pulmonary infection of P. carinii in SCID mice was completely cleared by reconstitution of the infected mice with immunocompetent spleen cells. IL-1 activity in the lung homogenate supernatant of these mice increased significantly after reconst...
