CONTENT OF ASCORBIC-ACID IN 13 TYPES OF T ISSUE AND ACTIVITY OF L-GULONOLACTON-OXIDASE IN THE EQUINE LIVER

At analyses of tissues of 10 horses the highest content of ascorbic ac id was determined in the adrenals of 2334 +/- 279 and in the hypophysi s of 1829 +/- 450 mug/g wet weight (ww). In the cerebellum the content of 424 +/- 49 was higher than in the cerebrum of 257 +/- 42 mug/g ww. The intestinal lymph nodes exhibited a content of 513 +/- 95 and the spleen of 454 +/- 44 mug/g ww. The content in the M. longissimus (of 1 47 +/- 26) and that of the heart of 122 +/- 10 mug/g ww was relative l ow. In the liver a formation of 498 +/- 62 mug ascorbic acid per gram and hour by the L-gulonolactoneoxidase was determined. Problems of the application of the ascorbic acid in horses are discussed.
