GCF RANKL and OPG levels were oppositely regulated in periodontitis, but not gingivitis, resulting in an enhanced RANKL/OPG ratio. This ratio was similar in all three periodontitis groups and may therefore predict disease occurrence.

This study demonstrates that RANKL and osteoprotegerin expression are differentially regulated in various forms of periodontitis, and the relative RANKL/osteoprotegerin ratio appears to be indicative of disease occurrence. This information may confer diagnostic and therapeutic value in periodontitis.

Aspergillosis; Aspergillus flavus; pseudo-nodular infiltrate in the right upper zone and a somewhat enlarged left hilum (Figure 1). Bronchoscopy membranous bronchitis; pseudomembranous necrotizing bronchial aspergillosis; renal transplantation; was performed on day 11 in order to obtain specimens for microbiological examination. Raised, cream-tracheobronchitis colored membranous plaques were observed to cover the bronchial mucosa in the distal trachea, the apical segment of the right upper lobe, and the distal half of

These results show that CsA and tacrolimus therapy has no significant effect on GCF MMP-8 levels, and gingival inflammation seems to be the main reason for their elevations.
