By using biotin labelled proteoglycan core protein and an avidin enzyme system, hyaluronan (hyaluronic acid) was visualised in specimens of human jejunum. Intense staining for hyaluronan was seen in the loose connective tissue of the villi and of lamina propria while the epithelial layer was unstained. The muscularis mucosae showed only faint staining. The accumulation of hyaluronan in the sube...

AIM To review the dental literature in terms of efficacy of soft tissue augmentation procedures around dental implants and in partially edentulous sites. METHODS A Medline search was performed for human studies augmenting keratinized mucosa (KM) and soft tissue volume around implants and in partially edentulous areas. Due to heterogeneity in between the studies, no meta-analyses could be perf...

Anterior portions of the central corneas of Fuchs' combined dystrophy were studied with the electron microscope, with the use of the same corneal buttons as in Part I of this study, in which changes of the posterior portions were reported. The epithelium showed various grades of cellular edema, mostly in the basal layer. Some of the edematous cells appeared to burst and coalesce to form subepit...

Statement of Problem: Various surgical procedures have been used to achieve root coverage and subepithelial connective tissue graft (SCTG) is identified as one of the most successful techniques. Recently, acellular dermal matrix allograft (ADMA) has been developed as a substitute for SCTG to avoid removing the palatal connective tissue. Purpose: The present study compared the clinical efficienc...
