After oocyte isolation from the follicle, calcium deposits are quickly depleted, and their replenishment occurs gradually during in vitro culture of the oocytes. Under the influence of verapamil, the dynamics of replenishment of intracellular calcium deposits were significantly changed. The decrease in calcium deposits is remarkable, especially in vacuoles and yolk granules. The replenishment of calcium deposits is significantly changed under the effect of verapamil. Intracellular or extracellular calcium could be the source for replenishment of calcium deposits during the in vitro culture of oocytes. A significant number of calcium deposits was also present in the mitochondria. The blockage of calcium influx from extracellular sources had a significant effect on the distribution of intracellular calcium deposits. During in vitro culture the amount of calcium deposits gradually increased. There was a significantly higher amount of calcium deposits in verapamil-treated oocytes than in oocytes cultured for the same time in a verapamil-free medium. In a further experiment (experiment 3) we observed changes in the ultrastructural distribution of intracellular calcium deposits in oocytes in which the calcium ion channels had been blocked by verapamil. The amount of calcium deposits in the oocyte and granulosa cells increased during oocyte meiotic maturation in vitro, especially in the nucleus, mitochondria, vacuoles and cytoplasm. We cannot exclude the possibility of calcium deposits in the endoplasmic reticulum being easily and quickly mobilised, and their efflux could occur at the earliest stages of specimen preparation. For this purpose we investigated the ultrastructural localisation of calcium deposits after blockage of the calcium channels which mediate the influx of extracellular calcium into the cell. The acetic acid in this fixative lyses red blood cells and dissolves small iron and calcium deposits in tissue.
