| Popis: | When bovine articular cartilage was incubated in Ringer's solution, considerable amounts of proteoglycan were washed out of the cartilage. Thus, 4% of the proteoglycan was lost into the medium during an incubation of 4 hours. Subsequently, it was found that ionic aqueous media like saline or Ringer's solution extracted much more proteoglycan than ion-free media like distilled water or a variety of carbohydrate containing solutions. In separate experiments, it could be shown that solutions of 20% sorbitol and 2% mannitol exhibited particularly low proteoglycan extracting properties. It was found that the extraction of proteoglycan was dependent on the ion concentration in the aqueous media. The extraction of proteoglycan by sodium chloride was negligible at NaCl concentrations of 0.1% and lower. Proteoglycan loss from cartilage was only induced at 0.9% NaCl. Using intact rat femoral heads it could be shown that the elution of proteoglycan from cartilage occurred as well when the cartilage was intact. Here, the elution occurred at a slower rate but the differences between ionic and ion-free solutions were greater. By electronmicroscopic examination of bovine cartilage incubated in different media, it was observed that Ringer's solution induced a more uneven and rougher appearance of the cartilage surface than did 10% mannitol solution, indicating that probably a denudation of collagen fibers occurs on the loss of proteoglycan from the cartilage. Because the observed proteoglycan washout occurred within rather short periods of contact of the cartilage with the medium, it is concluded that this may be of relevance for the clinical situation during arthroscopic procedures. The use of preferably isotonic carbohydrate solutions like 5% mannitol is suggested to prevent unnecessary loss of proteoglycan from hyaline cartilage. |
