Wound dressing.

Abstract

Dressings are applications for wounds, burns, and ulcers. Dressings should be regarded as supportive of healing; they are desirable but not essential in an emergency. This article reviews measurement of wound healing and the functions of wound dressings. A variety of dressings and their respective advantages and disadvantages are discussed.

Adherence of Plasmodium falciparum to chondroitin sulfate A in the human placenta.

Women are particularly susceptible to malaria during first and second pregnancies, even though they may have developed immunity over years of residence in endemic areas. Plasmodium falciparum-infected red blood cells (IRBCs) were obtained from human placentas. These IRBCs bound to purified chondroitin sulfate A (CSA) but not to other extracellular matrix proteins or to other known IRBC receptors. IRBCs from nonpregnant donors did not bind to CSA. Placental IRBCs adhered to sections of fresh-frozen human placenta with an anatomic distribution similar to that of naturally infected placentas, and this adhesion was competitively inhibited by purified CSA. Thus, adhesion to CSA appears to select for a subpopulation of parasites that causes maternal malaria.

Influence of filler parameters on the mechanical coherence of dental restorative resin composites.

Next to the presence of (chemical) coupling between filler and resin, filler particle size is important for the mechanical coherence of dental resin composites which are used for posterior restorations. In the range of the current composites a smaller particle size is desirable. The better mechanical coherence for composites with smaller particles found in an in vitro erosive wear test is probably related to the size of food fibres, which are part of the erosive medium. It appears that there is a critical value of the filler particle size (1.3-1.5 microns), under which the food fibres are not able to penetrate in the interparticle space, so the erosive capability of the erosive medium will be reduced.

Porphyromonas gingivalis endotoxin affinity for dental ceramics.

This study evaluated the effects of chemical composition, surface treatment, and initial exposure dose on Porphyromonas gingivalis lipopolysaccharide adherence to and elution from dental ceramics. Lipopolysaccharide, commonly known as endotoxin, can initiate a variety of biologic responses. Opaque, body, and Dicor ceramic disks were individually exposed to 250, 1000, or 2500 EU/ml 3H-lipopolysaccharide and incubated for 24 hours at 37 degrees C. Disks were then transferred to fresh lipopolysaccharide-free water and incubated for up to 96 hours to evaluate elution. Mean initial lipopolysaccharide adherence ranged from 0.397 +/- 0.048 EU/mm2 to 5.056 +/- 0.117 EU/mm2. Greater initial exposure levels resulted in greater adherence, and at higher lipopolysaccharide exposure levels, lipopolysaccharide adherence differences were based on ceramic type. Mean lipopolysaccharide elution levels ranged from 0.063 +/- 0.02 EU/mm2 to 0.00 EU/mm2 at 96 hours for all groups. Greater initial adherence resulted in greater elution. Ceramic type did not affect elution. Surface finish affected elution at the 2500 EU exposure level. The affinity of lipopolysaccharide for dental ceramics could contribute to a periodontal inflammatory process.
