THE ACTIVITY OF THE L-GULONOLACTONE-OXIDA SE IN THE KIDNEY AND THE CONTENT OF ASCORBIC-ACID IN THE KIDNEY, IN THE LIVER AND IN THE PLASMA OF CHICKENS, DUCKS, GEESE AND QUAILS

At analyses of the supernatant of homogenates of the kidney for the ac tivity of the L-gulonolactone-oxidase a high activity existed in 6 wee ks old quails (value: 691 +/- 132) and in 8 weeks, old chickens (546 /- 88), a moderate high in 7 weeks old ducks (254 +/- 47) in 1 year ol d hens (213 +/- 41) and in 1 year old ducks (172 +/- 60), and a low in 10 weeks old geese with the formation of 95 +/- 27 mug ascorbic acid per g tissue in 60 minutes from L-gulonolactone. The highest content o f ascorbic acid in the liver was determined in that of the chickens (5 20 +/- 31) and the lowest in that of the geese of 256 + 60 mug/g wet w eight. The kidneys of the 7 weeks old ducks with a value of 269 +/- 39 hat the highest and that of the 1 year old ducks with a content of 17 3 +/- 29 mug/g wet weight the lowest content.
