Disease relevance of Ear Cartilages

• In a case of relapsing polychondritis, ultrastructural study of ear cartilage using tannic acid staining showed patterns of degradation of elastic and collagen fibres [1].

High impact information on Ear Cartilages

• Chondrocytes, isolated from elastic ear cartilage of young rabbits, were grown in monolayer cultures in Ham's F-12 medium [2].
• Acute inflammation was limited to areas where Histoacryl escaped from between the bone graft and ear cartilage to contact well-vascularized soft tissue [3].
• Twelve rabbits had Proplast (a woven combination of Teflon and organic fibers), Silastic, Supramid polyfilament surgical sheeting, and ear cartilage implanted [4].
• The 70,000 dalton, [3H]valine-labeled protein of both the aorta and ear cartilage was precipitated by elastin-specific antibody prepared against hamster insoluble aorta elastin, but no higher molecular weight protein was immunoprecipitated [5].
• Resulting assays of the ear cartilages, after four treatments over a 2-day period, demonstrated a nearly twenty-fold increase in gentamicin levels in the iontophoresis-treated ears, compared to low levels in the soaked ears [6].

Associations of Ear Cartilages with chemical compounds

• The stimulatory effects of N6, O2'-dibutyrl adenosine 3',5'-monphosphate on proteoglycan released from immature rabbit ear cartilage were studied in viltro [7].
• This result, together with enzyme inhbitor studies, leads us to speculate that the observed action of dibutyryl cyclic AMP on rabbit ear cartilages may be mediated by the neutral proteases [7].
