Abstract
THE carbonic anhydrase present in the uterus of hens is involved in the calcification of the egg-shell1. The activity of this enzyme in the uterus seems to be greater in ‘good’ than in ‘poor’ layers or in non-layers2. Recently we pointed out that this enzyme is located at the apical pole of the cells of the tubular glands3 (Fig. 1). We succeeded in demonstrating, by a histochemical method4, that the reactivity of carbonic anhydrase is reduced in the uterus gland cells in moulting hens, whereas moulting has no influence on the carbonic anhydrase activity in the erythrocytes (Fig. 2). These results suggest an enzyme activation or an induction of enzyme synthesis similar to the effect of progesterone on the carbonic anhydrase in the endometrium of mammals5,6.
