In the retina of vertebrates, carbonic anhydrase (CA) is present in the cells of the pigmented epithelial layer and in Muller cells. Its activity has been demonstrated to increase during development, corresponding to the maturity of the tissue. We have studied CA activity, either during embryonic development or after hatching, in the retina of 3 species of birds, having precocial or atricial broods. The research has been carried out, by histochemical and biochemical methods, in pigeon as an example of atricial brood, and in fowl and quail, that represent examples of precocial broods. Our results confirmed that CA activity may be taken as a marker of retina maturity, or, more precisely, of Muller cells maturity, for any species of vertebrates, depending solely on maturity of the offspring at birth time.
在脊椎动物的视网膜中，碳酸酐酶（CA）存在于色素上皮层细胞和穆勒细胞中。其活性已被证明在发育过程中会增加，这与组织的成熟度相对应。我们研究了3种具有早成雏或晚成雏的鸟类视网膜在胚胎发育期间或孵化后的CA活性。以晚成雏的鸽子为例，以及以早成雏的家禽和鹌鹑为例，通过组织化学和生化方法进行了这项研究。我们的结果证实，对于任何脊椎动物物种，CA活性都可以作为视网膜成熟度的标志，或者更准确地说，作为穆勒细胞成熟度的标志，这仅取决于出生时后代的成熟度。
