Hydroxyproline concentrations in ocular tissues of Arabian camel (Camelus dromedarius Linn.)
Hydroxyproline (Hyp) concentrations (total, free, peptide-bound and protein-bound) in camel eye tissues were determined. Total Hyp concentration was highest in iris, followed by ciliary body, sclera, cornea, lens and retina; the difference between total Hyp concentration of iris and sclera (P < 0...

Zusammenfassung: | Hydroxyproline (Hyp) concentrations (total, free, peptide-bound and protein-bound) in camel eye tissues were determined. Total Hyp concentration was highest in iris, followed by ciliary body, sclera, cornea, lens and retina; the difference between total Hyp concentration of iris and sclera (P < 0.05) and cornea, lens and retina (P < 0.001) was statistically significant. Cornea had the highest concentration of free Hyp, followed by ciliary body, retina, iris, sclera and lens (P < 0.001). Peptide-bound Hyp concentration was highest in iris, followed by lens, cornea, ciliary body, retina and sclera (P < 0.001). Iris also had the highest concentration of protein-bound Hyp, followed by ciliary body, sclera, cornea, retina and lens; the difference in the protein-bound Hyp concentration between iris and sclera (P < 0.05) and cornea, retina and lens (P < 0.001) was statistically significant. Iris was also found to have the highest concentration of collagen, followed by ciliary body, sclera, cornea, lens and retina; the difference between the collagen concentration of iris and sclera (P < 0.05) and cornea, lens and retina (P < 0.001) was statistically significant. These variations may result from differences in the collagen structure and/or composition in these tissues. |
