Maģistra darbs uzrakstīts latviešu valodā uz 54 lapām.
Mērķis: Novērtēt suņu sklēru ar ADAMTS10 gēna mutāciju pielietojamību PAKG rašanās mehānismu izpētē.
Metode: Noskenējot sklēru paraugus ar WAXS metodi, tika izveidotas šķiedru orientācijas polāro vektoru, sakārtotības un kopējā kolagēna kartes. Šķiedru sakārtotības pakāpju un kopējā kolagēna vērtības statistiski salīdzinātas suņiem bez un ar ADAMTS10 gēna mutāciju.
Secinājumi: Kolagēna struktūra nozīmīgi atšķiras sklēras peripapillārajā un vidēji mugurējā zonā starp jauniem suņiem bez un ar ADAMTS10 gēna mutāciju. Atšķirības varētu būt saistītas ar iepriekš aprakstītām biomehāniskām un bioķīmiskām sklēras izmaiņām, kas suņiem ar ADAMTS10 gēna mutāciju, veicina glaukomas attīstību.

The Master thesis ir written in Latvian, contains 54 pages. Aim: To assess ADAMTS10 mutant dogs sclera’s possible use in POAG development studies. Methods: Sclera samples were scanned with WAXS. Collagen fiber orientation polar vector, anisotropy and total collagen maps were created. Pooled anisotropy and total collagen values were compared for significant differences between healthy and mutant dogs. Conclusions: Significant differences in collagen architecture between healthy and mutant dogs were found in regions of the peripapillary and midposterior sclera. These differences may be associated with biomechanical and biochemical scleral differences previously noted and may contribute to predisposition of mutant animals to glaucoma development. Key words: glaucoma, sclera, collagen, canine, WAXS
