Substance p and the isolated spinal cord of the frog: An electrophysiological and immunohistochemical study
Abstract 1. The action of substance P (SP) on the isolated, hemisected and quadrisected spinal cord of Rana esculenta, and its distribution, were studied. 2. The ventral and the dorsal quadrants withExpand

Melatonin and LSD induce similar retinal changes in the frog
This work is based on histological examination with the light microscope of Nissl-stained frogs’ retinae following melatonin and lysergic acid die~ylamide (LSD) administ~tion. In a previous paperExpand

Drugs and the frog retina: Effect of dopaminergic agents on the pigment screening of light- and dark-adapted frogs
This is a study, using the light and electron microscope, of the action of a dopamine agonist (apomorphine) and of a dopamine antagonist (haloperidol) on the retinal pigment screening (PS) of light-Expand

Modification of the pigment screening of the frog retina following administration of neuroactive drugs.
Pigment screening (PS) occurs in the retina of lower vertebrates and consists of the bidirectional migration (vitreally or sclerally) of melanin granules into processes of the pigment epithelium thatExpand

GLYCOPROTEIN CHANGES DURING THE DEVELOPMENT OF HUMAN BRAIN
Brain glycoprotein sugars were studied during human brain development. Marked changes were found in the sugar content of glycopeptides derived from soluble and insoluble glycoproteins, showing aExpand
