...Norman Grim The retina of the common mole, Scalopus aquaticus , has been studied with the transmission electron microscope. Structures examined include: pigment epithelium, outer and inner segments of the sensory cells, and synaptic ribbons of the outer plexiform layer. Rods and cones described...

... after bleeding, and the phagosome numbers per 5 pigment cells counted and compared with control retinae. A severe decrease was evident after bleeding and the decrease leveled off 48 h afterwards. Reinfusion with dextrose had a positive beneficial effect. 10 03 1988 27 04 1988 15 7 2008...

...David T. Yew; Winnie W.Y Li; D.R. Zhang; Z.B. Luo The activities in mouse retinae were evaluated after 6-hydroxydopamine injection. A significant increase in labeled leucine uptake was evident in the photoreceptor layer. Latex uptake in the pigment epithelium showed no changes. Denervation...

...José A. Armengol; Francisco Prada; José M. Génis-Gálvez The present work describes the presence of some photoreceptor nuclei in the embryonic and adult chick retina which are situated outside of the external limiting membrane. We also discuss their possible degenerative character. 15 03 1984...

...A. Quesada; J. Ambrosíani; M.E. Dorado; J.M. Génis-Gálvez On a morphological and ultrastructural level, we studied a thickening which appears on the ascending prolongation of bipolar cells in the chick retina. We first observed this thickening on day 10 of incubation and it remains unchanged...

...A. Quesada; C. Chmielewski; A. Espinar; J. Ambrosiani; F.A. Prada Ultrastructurally, two different bipolar cell types can be distinguished in the retina of the chick embryo: one pale or electron-lucent and the other dark or electron-dense. The different electron density was seen over the whole cell...

...David T. Yew; D. Da Ren Zhang; Betta S.W. Hui; Winnie W.Y. Li The development of the retina of the albino rat was studied after sectioning of the optic nerves on the 2nd postnatal day. The 2nd day represents a stage at which the retina shows only the ganglion cell layer clearly delineated from...

...David T. Yew; David S.C. Tsang; Y.W. Chan The alkaline phosphatase and DNA-RNA activities in the retinas of young and old albino mice were determined histochemically after photic exposure. Different patterns between the two age groups were obtained for the alkaline phosphatase reaction before...

...David T. Yew; Yau-wa Chan The effects of laser irradiation on light-adapted (normal cycle) and dark-adapted rat retinas were compared. The dark-adapted retinas suffered very extensive damage following laser treatment. 21 09 1971 11 7 2008 © 1978 S. Karger AG, Basel 1978...

...David T. Yew; H.C. Liu; Y.W. Chan; Spencer Lam After irradiation of the retinae of albino mice with a dose of 13 J, using a ruby pulse laser, the lesions were followed for a period of 60 days. Severe degenerations were observed in the outer layer 2–9 days after irradiation. By the 21st day after...

...A. Spadaro; I. De Simone; D. Puzzolo Synaptic ribbons of the outer plexiform layer in the retina of albino rats are examined, with particular regard to their ultrastructure and to their chronobiological behaviour. As to the ultrastructure, aside from the typical lamellar and granular morphology...

...J.A. Armengol; F. Prada; J.M. Génis-Gálvez The cones of the chameleon retina have, in the scleral portion of their inner segment, an oil drop whose morphology is similar in all the photoreceptors possessing this droplet. The irregularities in the membrane surrounding the lipid matrix show close...

...David T. Yew Aging of the retina and optic nerve was studied in 2.5- to 9-month-old albino mice. A change was found in the number of visual cells and in the distribution of large versus small optic nerve fibers. No significant change was found in the number of retinal phagosomes and in the total...

...David T. Yew; C.L. Wong; Yau-wa Chan Retinas of laser-irradiated mice were studied in the first 24 h after irradiation. Decrease in Na + and K + concentrations and in phagosome number and increase in pyknotic cells were observed several hours after irradiation. 23 12 1977 9 7 2008...
