, Novato, CA). Flash electroretinograms (ERGs) with overnight [http://en.wikipedia.org/wiki/MAPK MAPK] dark adaptation were recorded 7 days before treatment and 7 days after treatment. The rats were anesthetized with an i.p. injection of 10% chloral hydrate, and their pupils were dilated with 0.5% tropicamide and 0.5% phenylephrine hydrochloride eye drops. The body temperature was maintained with a heating pad setting to 37��C during the procedure. ERGs were recorded with a corneal gold wire electrode, a reference electrode at the head, and a ground electrode in the tail. All procedures were performed in dim red light, and the rats were kept warm during and after the procedure. The responses to a light flash (3.0 candela��seconds/m2) from a photic stimulator were amplified, and the preamplifier bandwidth was set at 0.2 to 300 Hz. The amplitude of the a-wave was measured from baseline to the maximum a-wave trough, and the amplitude of the b-wave was measured from the maximum a-wave trough to the maximum b-wave peak.31, 32?and?33 Data are expressed as mean �� SD. Assuming that the data meet normal distribution and that variances are equal, the one-way analysis of variance, followed by validation using Student-Newman-Keuls tests, was used to analyze the statistical differences in retinal thickness, ERG data, and cell number among groups. The analysis was [http://www.selleckchem.com/products/epz-5676.html selleck chemicals llc] performed by computer software (SPSS 17.0 for Windows; SPSS Inc., Chicago, IL). For all comparisons, P disorders of the outer retinal layer are observed in the model of RD at 7 days after RD.23?and?25 There were no significant histopathological changes in the inner retina at 7 days after RD, but evident changes were detected in the outer neural retina. Both inner and outer segments of photoreceptor cells were disordered and shortened. Both pretreatment and post-treatment of necrostatin-1 led to significant preservation in histoarchitecture of the outer retina, compared with vehicle-treated controls or inactive necrostatin-1�Ctreated animals (Figure 1, A and B). The ratio [http://www.selleckchem.com/products/ly2109761.html selleck screening library] of ONL thickness was reduced after RD (0.68 �� 0.04) but was thicker in the necrostatin-1 pretreatment groups (0.87 �� 0.06) (n = 6 per group, P
