On the basis of its overall profile, (3R)-3-1-(3-phenoxypropyl)-1-azoniabicyclooctane bromide (aclidinium bromide) emerged as a candidate for once-daily maintenance treatment of COPD. A series of novel quaternary ammonium derivatives of (3R)-quinuclidinol esters were synthesized and evaluated. more The objective of this work was to discover a novel, long-acting muscarinic M(3) antagonist for the inhaled treatment of chronic obstructive pulmonary disease (COPD), with a potentially improved risk-benefit profile compared with current antimuscarinic agents.

Treatments allowed bone regeneration that increased with time, however surgical cavities treated with the autogenous graft had more bone formation than those with calcium phosphate cement. Both treatments presented an increase in bone healing with time. Calcium phosphate cement at 6 weeks presented similar results to autogenous bone at 3 weeks. Data analysis showed that the autogenous bone graft had significantly more new bone compared with calcium phosphate cement at 3 and 6 weeks. Data obtained from the histomorphometric analysis were statistically analyzed using 2-way analysis of variance and the Tukey& amp amp amp amp amp amp amp amp amp amp amp amp amp amp amp amp amp amp amp amp amp amp amp amp amp #39 s test. The microscopic analysis of the samples showed bone healing with both calcium phosphate cement and autogenous bone graft. Data analysis included qualitative assessment of the calvarial specimens and histomorphometric analysis was used to quantify the amount of new bone within the defects. The animals were killed at 3 or 6 weeks (n=5). One of the defects was filled with the calcium phosphate cement, and the other received autogenous bone harvested from the calvaria. Circular bone defects (8mm) were made in both parietal bones of 10 rabbits. more To assess bone regeneration in critical sized defects in the rabbit calvarium, filled with the bone substitute calcium phosphate cement. To assess bone regeneration in critical sized defects in the rabbit calvarium, filled with the bo.
