ELECTRON MICROSCOPIC DEMONSTRATION OF ZINC IN THE HIPPOCAMPAL FORMATION USING TIMM'S SULFIDE-SILVER TECHNIQUE

IBATA, YASUHIKO, OTSUKA, NAGAYASU·1969·Journal of Histochemistry & Cytochemistry

Abstract

Ultrastructural localization of zinc in the hippocampus of rabbits and rats was investigated by the application of Timm's sulfide-silver and zinc-dithizonate methods. Best results were obtained by fixation of tissue in 3% glutaraldehyde saturated with H 2 S, followed by treatment of small blocks of tissue with Timm's solution for 1 hr. In sections cut from these blocks, silver particles were found on the synaptic vesicles in the terminal boutons of the mossy fibers. The nervous tissue of the hippocampal formation was devoid of silver particles, as were the perikarya of the granular cells of the fascia dentata and the pyramidal cells of the hippocampus. The cytochemical significance of zinc in nerve endings of the granular cells is discussed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
