Influence of corticosterone on tracheal mucociliary transport in pigeons.
The effects of corticosteroids on tracheal mucociliary transport (MCT) were examined in pigeons. Intramuscular administration of corticosterone had no effect at 1.0 mg/kg, while at a larger dose of 5.0 mg/kg, it slightly, but significantly increased the MCT rate. Metyrapone significantly decreased the MCT rate, and the inhibitory action was blocked by 1.0 mg/kg corticosterone. The present study...
متن کاملEffect of aging on tracheal mucociliary clearance in beagle dogs.
Tracheal mucous velocity measurements were made in 24 beagle dogs in five age groups, using a gamma camera to detect movement of instilled 99mTc-macroaggregated albumin. Age groups were defined as immature (9-10 mo), young adult (2.8-3.0 yr), middle aged (6.7-6.9 yr), mature (9.6-9.8 yr), and aged dogs (13.6-16.2 yr). Mean velocities were 3.6 +/- 0.4 (SE) mm/min in the immature dogs, 9.7 +/- 0....
متن کاملEffect of pranlukast, an oral leukotriene receptor antagonist, on leukotriene D4 (LTD4) challenge in normal volunteers.
BACKGROUND There is increasing evidence to show that leukotrienes are important mediators in asthma. Leukotriene receptor antagonists protect against antigen and exercise challenges in patients with chronic asthma. A study was undertaken to investigate the activity of the leukotriene receptor antagonist pranlukast (SB 205312, ONO-1078) in blocking bronchoconstriction induced by leukotriene D4 (...
متن کاملEffect of needle puncture and electro-acupuncture on mucociliary clearance in anesthetized quails
BACKGROUND Acupuncture therapy for obstructive respiratory diseases has been effectively used in clinical practice and the acupuncture points or acupoints of Zhongfu and Tiantu are commonly-used acupoints to treat patients with the diseases. Since the impaired mucociliary clearance is among the most important features of airway inflammation in most obstructive respiratory diseases, the effect o...
