Abstract

Carbonic anhydrase activity was studied during development and regression of the quail mesonephros by in situ and extra situm investigation. A close correlation was noted between enzyme expression and tissue morphofunctional state. Carbonic anhydrase appears in early development; its highest activity is reached when the kidney is actively secreting, followed by a decrease concomitant with tissue involution. The main localization of the reaction product is the distal tubule showing strongly positive cells intercalated with clear, negative ones. In the functional organ, staining was found at the level of transitional and connecting segments and Wolffian duct. The comparison with the histochemical pattern of the quail metanephros suggests that the functional meaning of renal carbonic anhydrase might be the same both in transitory and in permanent kidney.
