[Changes in the ultrastructure of the chloride cells of sturgeon during adaptation to a hypertonic medium].
Alterations in the ultrastructure of chloride cells of young sturgeons Acipenser guldenstadti Brandt in the process of adaptation to hypertonic medium (S=105%) were under study. In the process of this adaptation thread-shaped long mitochondria became shorter, their random position was substituted by orientation in parallel to the axis of the cell. The amount of mitochrondria increased. A great number of vacuoles appeared in the cytoplasm. The character of the endoplasmic reticulum changed. The obtained data on the ultrastructure of chloride cells of the sturgeon confirm and supplement earlier light microscopy investigations of chloride cells of the sturgeon. The changes of the ultrastructure of chloride cells are interpreted as functional and adaptational ones.
