“…CA activity has also been reported in various parts of the eye. The histochemical location of the enzyme in the pigment epithelium and glial elements of the retina (Korhonen & Korhonen 1965;Leder 1966;Bhattacherjee 1971;Musser & Rosen 1973a,b) suggests a role in carbon dioxide metabolism and ionic changes probably involved in the propagation of the nerve stimuli. The histochemical methods of Hausler (1958) and Hansson (1967) are those most commonly used for the demonstration of CA activity in the retina.…”

The occurrence of carbonic anhydrase isoenzymes C and B in the retina of the human eye was examined with specific antisera against these enzymes. Immunological analysis were carried out by the double diffusion method of Ouchterlony, and the localization of the enzymes was studied by an application of immunoperoxidase (PAP) technique. A large amount of isoenzyme C was detected in tissue sections from the human retina, whereas the isoenzyme B was totally absent. Isoenzyme C was considered to be located primarily in the glial elements of the retina, correlating with the earlier findings obtained by traditional metal salt methods.

“…Using the modified Huusfer ( 1 958) method, Sky1 (1964) observed an intense CAH reaction in pancreatic islets from different species, including mouse, which was suggested to be ounspecificcc. The specificity of the Kurata and Hausler methods has been questioned also by others (CJ: Maren 1967), whereas the specificity of the Hausler method has Accepted 28.xi.78 been accepted by other authors (Korhonen & Korhonen 1965).…”

Histochemical staining for carbonic anhydrase (CAH) was demonstrated in the mouse pancreas. Light microscopically, a strong reaction for CAH was found in the B‐cell region of the islets, in blood vessels inside and outside the islets, and in centroacinar cells and ductules. In contrast, no distinct reaction was seen in the peripheral A‐ and D‐cell regions of the islets, or in the cytoplasm of the acinar cells. A weak, irregular staining could, however, be observed in some nuclei of the acinar parenchyma. A newly‐developed ultrastructural modification disclosed a distinct reaction in a varying number of the secretory granules of the B‐cells, whereas a sparse, irregularly‐distributed reaction was observed in the nuclei and cytoplasmic ground substance, and in association to the plasma membranes and microvilli of these cells. The CAH reaction was in all portions of the pancreas abolished by acetazolamide. The specificity of the results is discussed. The findings are suggested to indicate presence of a true CAH activity in the B‐cells of the mouse pancreas.
