Carbonic anhydrase and fetal hemoglobin in tyrotoxicosis.
I N A RECENT REPORT Lie-Injo and 1 described a condition char.. acterized by a deficiency of both types I and 112 (also designated B and C) of carbonic anhydrase. This deficiency, though associated with a high level of fetal hemoglobin, was not due to hemoglobinopathy, hereditary persistence of fetal hemoglobin, or any of the known types of thalassemia. Because of lack of proof of hereditary ba...
متن کاملReduced Erythrocyte Carbonic Anhydrase Activity by Swietenia Macrophylla Seeds in Diabetic Rats
Carbonic anhydrases (CAs, EC 4) are zinc containing metalloenzymes. The active site of these enzymes contains a Zn (II) ion Co-ordinated by three histidine residues and a water molecule/hydroxide ion. Four distinct gene families encode them and distributed throughout the phylogenetic tree. Presently 16 different CA isoforms of alpha family have been isolated and characterized in mammals. They c...
متن کاملErythrocyte catalase and carbonic anhydrase activities in lung cancer.
AIM To study the relationship between the pathogenesis of lung cancer and antioxidant status and acidic media by measuring the activities of erythrocyte catalase (CAT) and carbonic anhydrase (CA). METHODS A total of 26 patients with lung cancer and 15 healthy individuals were included in the study. The CAT and CA activities of erythrocytes were defined. The catalase (CAT) activity of erythroc...

Logan, R. W., Crooks, S. M., Hutchison, J. H., and Kerr, M. M. (1973). Archives of Disease in Childhood, 48, 256. Blood carbonic anhydrase activity in the newborn. Erythrocyte carbonic anhydrase activity was measured in 7 adults, 12 mature newborn infants, 12 preterm low birthweight infants, 9 'dysmature' infants, 33 infants with the respiratory distress syndrome (RDS), and 5 infants who had re...
متن کاملTransport Activity of the Sodium Bicarbonate Cotransporter NBCe1 Is Enhanced by Different Isoforms of Carbonic Anhydrase
Transport metabolons have been discussed between carbonic anhydrase II (CAII) and several membrane transporters. We have now studied different CA isoforms, expressed in Xenopus oocytes alone and together with the electrogenic sodium bicarbonate cotransporter 1 (NBCe1), to determine their catalytic activity and their ability to enhance NBCe1 transport activity. pH measurements in intact oocytes ...
