TL;DR: The results strongly suggest that the (Na+-K+)-ATPase system in the stria vascularis plays the primary role in the maintenance of the cochlear cation gradients, while the contribution of Reissner's membrane to this process can only be very minor.

TL;DR: It is unlikely that the 11-cis retinol dehydrogenase from pigment epithelium is directly involved in providing 11- cis retinaldehyde from rhodopsin regeneration, but it may serve to make available 11-Cis retinehyde from Rhodopdsin, digested in phagocytized rod sacs, for the synthesis of visual pigment by the visual cells.

TL;DR: Substantial, seasonally varying amounts of opsin are present in cattle rhodopsin preparations, which cannot be converted to rhodopin by prior dark adaptation of the excised eyes, and this preparation is of high purity and can be stored for long periods of time.

TL;DR: Quantitative analysis of the phospholipids by two-dimensional thin-layer chromatography showed that the three major phospholipsids are: phosphatidyl ethanolamine, phosph atidyl choline and phosphAtidyl serine.
