[Chloride cells of the gills and the interrenal gland of Dasyatis pastinaca (L.) (Elasmobranchii) skates during adaptation to distilled sea water].
During adaptation of the skate Dasyatis pastinaca (L) to distilled sea water (7.1%) resulted in decreasing concentration of sodium, urea in blood serum, reduction in the chloride cells volume, their nuclei and increase of the apical part of the cell free from mitochondria (and occupied by the endoplasmic reticulum) are observed. Owing to uniformity of the morphometric changes of the chloride cells revealed in two types, during adaptation of the skate to the distilled sea water, as well as adaptation to its increased salinity, it is possible to conclude that in the gill of selachians there are chloride cells of one type with various functional activity. Adaptation of the skate to the distilled sea water is connected with removal of lipid inclusions out of the cells of the interrenal gland.
