CYTOCHEMICAL, SCANNING ELECTRON MICROSCOPY X-RAY MICROANALYSIS AND SPECTROPHOTOMETRIC STUDY OF Ca2+ CONTENTS AND DISTRIBUTION IN THE RAT PINEAL GLAND DURING ONTOGENETIC DEVELOPMENT
by Luciano Munoz Barragan; Dolores L. Pizarro, M.Benita Gomez Esteban, Juan C. Carvajal, Santiago Carbajo and Antonio J. Alvarez-Morujo

Abstract

Using potassium pyroantimonale. scanning electron microscopy, X-ray microanalysis and spectrophotometry we observed that Ca2+ is undetectable in foetuses of 19 and 20 days and new-born rats whereas it increases progressively as from the 10th day of extrauterine life. Further, calcium-poor pinealocytes and others richer in cytoplasmic and nuclear calcium were clearly present as from day 30 of life.
