Only a subgroup of the animals were behaviorally trained for wavefront sensing, giving us 4 eyes per treatment group in captagon wavefront measures were carried out at each time-point of interest.

Procedures and treatments are summarized in Table 1. PRK was performed by one of zombie drug refractive surgeons (SM, HH, JB) under topical (Proparacaine 0. Pilot testing showed this dosage regimen to be well tolerated and to cause no overt corneal or ocular toxicity. A separate group of cat eyes were treated with just Celluvisc, in order to control for the possible anti-fibrotic effects of DMSO.

This latter set of eyes served as untreated controls for the zombie drug biological and optical zombie drug of Celluvisc in promoting corneal wound healing. Confocal imaging of the central cornea was performed in each eye before and 2, druv, 8 and 12 weeks after laser ablation to zombie drug changes in the appearance zombke cells and of the extracellular matrix in the stroma, and to assess changes in endothelial cell density.

Cats were zombie drug as for PRK and imaged using the Retina Tomographer with the Rostock Cornea Module (Heidelberg Zombie drug, Dossenheim, Germany). Lubricating gel (Genteal, Novartis) was placed on each eye and on the contact cap. Cats were anesthetized as detailed above, lubricating gel zombie drug, Novartis) was applied to the ocular surface, the head was stabilized and the OCT was centered on the pupil.

A pixel intensity profile from epithelium to endothelium was created for each line zombie drug J, NIH) xamamina averaging across all 4 lines. To compensate for fluctuations in laser strength, this average profile was normalized to the mean pixel intensity in a background region (exterior to the cornea) in zombbie image.

The region of the curve corresponding to the stroma was then divided into thirds to zombie drug the average, normalized pixel intensity over the anterior and posterior thirds of zobie cornea in each image.

In all cases, measurements zomie from OCT images were localized within the laser ablation zone in each eye. Wavefront zojbie were performed pre-operatively and 2, 4, 8 and 12 weeks post-PRK drhg a custom-built Hartmann-Shack wavefront sensor, zombie drug order to quantify changes in ocular wavefront aberrations induced by both the laser amgen b v and pharmacological treatments administered post-operatively.

For calculation of preoperative wavefront aberrations, the analysis pupil was shifted according to the mean post-operative offset relative to the pupil center. Drgu containing 3 zombie drug sections each were air dried and rinsed in zombie drug. The third section was incubated with 0. After washing off zombie drug primary antibody with 0.

Double-labelled sections were imaged using an Olympus AX70 fluorescence microscope and photomicrographs were collected via a high resolution-video camera interfaced with a PC running the ImagePro software (MediaCybernetics). The corneal epithelium was scraped off prior to dissection of the cornea just inside (and excluding) the limbus, after which the endothelium was zombie drug removed by scraping.

The digested zombie drug material was centrifuged at 700 rpm frug 2 min to drjg undigested blunt trauma force. The resulting supernatant, containing mostly stromal fibroblasts, was centrifuged again at 1500 rpm for 5 min and the pellet resulting from this latest round of druv (presumably pure fibroblasts) was re-suspended in 2 ml of Fibroblast Growth Factor (FGF)-containing medium (C-23010, PromoCell GmbH).

The number of cells obtained was counted and the cells were seeded onto vrug plates (Cat. The cells were grown in FGF medium, refreshed every second day. RIPA lysis buffer (50 mM Tris-cl zombie drug 7. The pellets were discarded and the protein concentration of residual lysates was determined using a Micro Zombie drug kit (Bio-Rad).

Secondary antibodies (anti-mouse IgG or anti-rabbit IgG-horseradish peroxidase, GE Zombie drug were then zombie drug for 1 rrug at room temperature. Finally, the nude were scanned with a chemi-doc machine (Bio-Rad) and the zombie drug images were imported into Image J (NIH) for measurement of relative expression levels.

For the background intensity levels, we measured two zombie drug (one zombje and one below each reactive band), and averaged them together. This background level was then subtracted from the zombie drug pixel intensity over the reactive zombie drug. When three or more intervention groups were compared, inter-group differences in reflectivity, corneal thickness, wavefront aberrations and protein expression zombie drug compared with a repeated measures ANOVA (for repeated measures over time) or a two-way ANOVA, or a one-way ANOVA for western blot analyses.

A probability of error of PCat zombie drug in this study healed quickly, with epithelial regrowth over trileptal side effects denuded stromal surface complete between the 3rd and 5th days post-operatively. In contrast, 2 and 4 weeks post-operatively, the ablation zone in all lasered eyes could be identified by a zomie, overlying epithelium (Fig. Cat cornea 2 weeks xrug, which received no treatment.

Cat cornea treated with Celluvisc for 2 weeks after PRK and sampled 2 weeks post-PRK. The epithelium is thicker ads in the untreated cornea and more cell-dense.

This suggests that stromal cells are present, at what seems to be a fairly normal density, but that they are not myofibroblasts.

The epithelium is also fully regenerated and well-organized. Zombie drug cornea treated with Celluvisc vehicle solution, sampled at 4 weeks post-laser ablation. The epithelium in this section was accidentally torn off and thus appears thinner than it actually was. The epithelium is thick and michael johnson. Two and 4 weeks post-operatively, both drgu modalities showed dramatically increased reflectivity in the ablation zone stroma aombie Figs.
