Seventeen asthmatic children under 5 years of age took part in a double-blind controlled trial of nebulized sodium cromoglycate solution. Daily symptom scores kept by the parents showed improvement in 11 children during active treatment, and a significant improvement in scores for cough by day and night was obtained for the group as a whole.

Stevens et al. [1] have reviewed a series of meta-analyses concerning the use of sodium cromoglicate (SCG) in childhood asthma, each carried out by a largely identical group of authors. Stevens et al. believe that the interpretations of these metaanalyses are all too strongly negative and that this has subsequently been reflected in international guidelines and consensus statements. They say th...

Cumulative dose response curves to inhaled methacholine were established in 24 "healthy" children of asthmatic parents and 7 healthy children of healthy parents. Atopic children of asthmatic parents demonstrated higher bronchial hyperreactivity (BHR) than nonatopic children. The BHR was about ten times less than in the atopic parents of asthmatic children, indicating marked increase in BHR with...

The output of the drug and the particle size produced by various nebulisers were assessed, and sensible nebulisation times for sodium cromoglycate calculated. Three of the four nebuliser systems tested produced over 80% of total drug output within the first five minutes of nebulisation. We suggest that five minutes is an optimum nebulisation time for sodium cromoglycate using these nebuliser co...

We wished to determine whether nebulized sodium cromoglycate (SCG) has bronchodilator effects in very young children. In 18 children born prematurely and studied at a median of 15 months of age, thoracic gas volume (TGV) and airways resistance (Raw), were measured and hence specific airways conductance (sGaw) was calculated before (baseline) and after nebulized saline, and then after sodium cro...

The objectives of this study were to investigate the temporal response of left ventricular (LV) matrix metalloproteinase (MMP) activity and collagen volume fraction (CVF) induced by an aortocaval fistula and the role of cardiac mast cells in regulating MMP activity. LV tissue was analyzed for MMP activity, CVF, and mast cell number in rats euthanized at 0.5, 1, 2, 3, 5, 14, 21, 35, and 56 days....

To compare the effectiveness of cromolyn sodium (CS) (10 mg) and nedocromil sodium (NS) (4 mg) administered by a metered dose inhaler (MDI) with a spacer device in preventing exercise-induced asthma (EIA), eight asthmatic children with EIA were studied in a randomized double-blind, cross-over, placebo-controlled study, CS and NS provided significant, comparable protection from EIA and both were...
