The localization of gamma-aminobutyric acid (GABA)- and L-glutamate 1 carboxy-lyase (GAD)-immunoreactive neurons was compared in the skate, frog, pigeon, chicken, rabbit, and man. Horizontal cells show both GABA and GAD immunoreactivity in the skate, frog, and bird. Certain amacrine cells show GABA and GAD immunoreactivity in all species. The distribution(More)
Pregnant squirrel monkeys were exposed to mercury vapor during approximately 2/3 of a pregnancy, at a concentration of 0.5 or 1 mg Hg/m(3) air for 4 or 7 h a day, 5 days a week. The offspring were sacrificed at different ages (gestational week 16 to 5 years). The eyes were enucleated and horizontal sections of the retina, comprising the optic disc and the(More)
PURPOSE To establish neuronal connections in the rod and cone pathway between laminated rabbit retinal transplants and the host retina. METHODS Fourteen adult rabbits received a complete full-thickness embryonic transplant. After survival times of 3 to 10 months, the retinas were studied under light microscope and with immunohistochemistry. Antibodies(More)
PURPOSE To establish the morphology of full-thickness neuroretinal grafts transplanted to hosts with degenerative photoreceptor disease. METHODS Twenty rhodopsin transgenic pigs received a neuroretinal sheet from a neonatal normal pig in one eye. Following vitrectomy and retinotomy with bleb formation, the grafts were positioned inside the bleb between(More)
The photosensory pineal complex of anurans comprises an extracranial part, the frontal organ, and an intracranial part, the pineal organ proper. Although the pineal organ functions mainly as a luminosity detector, the frontal organ may monitor the relative proportions of short and intermediate/long wavelengths in the ambient illumination. The major pathway(More)
PURPOSE To study whether diabetes could influence glial cells, retinal neurons, and pigment epithelial cells and if so, to evaluate whether any changes could be influenced by aminoguanidine (AG) or probucol (PB). METHODS Streptozocin (STZ)-induced diabetic male Wistar rats and age-matched control rats were fed a normal diet, addition of AG in the drinking(More)
The immunohistochemical distribution and ultrastructural immunolocalization of connexin43 (Cx43) in the neural retina of the rabbit was investigated. Cx43 immunolabeling appeared in the form of distinct puncta distributed on different kinds of glial cells and exclusively in the myelinated fiber region of the neural retina. Double-label immunohistochemistry(More)
Purpose: To determine whether long-term treatment with the anti-epileptic drug vigabatrin causes damage to rabbit retina. Methods: Five rabbits were treated continuously with a daily dose of vigabatrin solution per orally during a period of 1–8 months. Two rabbits receiving water were used as controls. Repeated full-field electroretinograms (every two(More)
We have determined the endogenous levels of neuropeptide Y-like immunoreactivity (NPY-LI) in retinal extracts from pigs, cats, rabbits, chickens, and frogs by radioimmunoassay (RIA). The NPY-LI levels varied among the species. The highest concentration was found in frog retina, where seasonal variations were seen, 861 +/- 31 pmol g(-1) wet weight in the(More)
