[The peroxisomes of Triturus cristatus (amphibian, urodele) adrenal cortex cells: peroxisome number as a function of steroidogenic activity].

Peroxisomes are scarce in the poorly active interrenal cells of hypophysectomized animals; their number increases drastically in cells which are stimulated by corticotrophic factors. A precise correlation appears thus to exist between the steroidogenic activity of the interrenal cells and the number of peroxisomes in these cells.
