Asthmatic Airway Inflammation is More Closely Related to Airway Hyperresponsiveness to Hypertonic Saline than to Methacholine

BACKGROUND Airway hyperresponsiveness (AHR) to direct stimuli, such as methacholine (MCh), is observed not only in asthma but other diseases. AHR to indirect stimuli is suggested to be more specific for asthma. The purpose of this study was to determine whether asthmatic airway inflammation is more closely related to AHR to hypertonic saline (HS), an indirect stimulus, than to MCh. METHODS Si...

minocycline is more potent than tetracycline and doxycycline in inhibiting mmp-9 in vitro

conclusions our results suggest that tetracyclines dose-dependently inhibit mmp-9 activity, and among the common clinical tetracyclines, minocycline provides the most potent inhibition of excess mmp-9 activity and its consequences. materials and methods an mmp-9-rich culture medium of u-937 cells was used as the source of the enzyme. serial dilutions of 5, 20, 100, 200, and 500 µm of each drug ...

Surfactant and allergic airway inflammation.

Pulmonary surfactant is a complex mixture of unique proteins and lipids that covers the airway lumen. Surfactant prevents alveolar collapse and maintains airway patency by reducing surface tension at the air-liquid interface. Furthermore, it provides a defence against antigen uptake by binding foreign particles and enhancing cellular immune responses. Allergic asthma is associated with chronic ...
