[Comparative study of effects of tannic acid and oxidized tannic acid on growth, body composition and biological utilization of nutriments in rats].
The nutritional effects of oxidized tannic acid in rats have been compared with the effects of tannic acid supplemented or not with a reductor: sodium sulfite. The results indicate that in the group which ingested oxidized tannic acid, fecal nitrogen excretion is lower than in the group which ingested tannic acid; its action on growth is mainly exerted by reduction of the retention coefficient; urinary nitrogen excretion being increased. With regard to the other groups of animals, oxidized tannic acid decreases the weight gain of the thymus and slightly increases the weight gain of the heart. Sulfite supplementation does not change the effects of tannic acid on growth; nevertheless, a higher weight gain of the kidneys is noted.
