Acute pseudoseptic arthritis is a very rare complication that is associated with intra-articular hyaluronic acid injections, which normally involve minimal risk. The most common adverse events that are caused by hyaluronic acid injections are inflammatory reactions or flares at the injection site. In this study, we described three cases of acute pseudoseptic arthritis that was caused by hyaluro...

CD44 is a polymorphic glycoprotein expressed on the surface of many tissues and cell lines which has been implicated in a number of cellular functions including lymphocyte homing to mucosal lymphoid tissue (Peyers patches), leukocyte activation, lymphopoiesis, and tumor metastasis. The predominant isoform found on human leukocytes, CD44H, is a receptor for hyaluronic acid. Because of the promin...

Objective To evaluate the efficacy of intra-articular viscosupplementation therapy with hyaluronic acid for pain relief of knee osteoarthritis, we conducted a meta-analysis of randomized, doubleblinded, placebo-controlled trials. Methods We searched systematically for randomized, double-blinded, placebo-controlled trials of hyaluronic acid (hyaluronan and hylan G-F20) for pain relief of knee os...

All major glycosaminoglycans except keratan sulphate are found in animal lung and pleura (Wusteman, 1972). Pleural fluids from patients with several pulmonary diseases contain mostly hyaluronic acid (Friman, Hellstrom, Juvani & Riska, 1977). The high concentration of hyaluronic acid in pleural fluid associated with mesothelioma is considered diagnostic of this disease (Havez, Degand, Boersma & ...

A readily available source of pure hyaluronic acid is a necessity in studies involving the ground substance of connective tissue and its relation to diverse spreading factors thought to be important in the pathogenesis of many bacterial diseases. Any objection that contamination with other mucopolysaccharides or protein of hyaluronic acid prepared from mammalian sources is generally likely, unl...

Although endovascular stenting has been used as an interventional therapy to treat cardio- and cerebro-vascular diseases, it is associated with recurrent vascular diseases following stent thrombosis and in-stent restenosis. In this study, a metallic stent was coated with dopamine-conjugated hyaluronic acid with different ratios of catechol group to improve hemocompatibility and re-endothelializ...

Ogston & Phelps (1961) found that hyaluronic acid markedly affects the partition of diffusible macromolecules between solutions of the polysaccharide and buffer. The authors explain the phenomenon as a steric exclusion of macromolecular solutes from solutions containing randomly coiled hyaluronic acid chains. From these results one can expect that hyaluronic acid and similar substances would ex...

BACKGROUND AND PURPOSE Dextranomer/hyaluronic acid copolymer implants are used in treating velopharyngeal insufficiency. These posterior nasopharyngeal implants can be mistaken for pathologic conditions such as retropharyngeal abscess on imaging. We studied the imaging appearance of dextranomer/hyaluronic acid copolymer implants in patients treated for velopharyngeal insufficiency. MATERIALS ...

An affinity immunological procedure for hyaluronic acid detection on tissue sections is described. This new, sensitive, and specific technique is based on the high affinity of hyaluronectin for hyaluronic acid, utilizing anti-hyaluronectin-hyaluronectin immune complexes. Elimination of binding when the reagent was supplemented with hyaluronic acid or when Streptomyces hyaluronidase-digested tis...
