The study was conducted to investigate the effect of vitamin A, B1 and B6 deficiency on oxalate metabolism in rats. A significant hyperoxaluria was the common observation in all the three vitamin deficiencies (vitamin B6 greater than vitamin A greater than vitamin B1). The activities of hepatic glycolate oxidase and glycolate dehydrogenase were markedly enhanced in vitamin-A- and vitamin-B6-deficient rats. However, lactate dehydrogenase levels remained unaltered in these deficiencies as compared to their respective pair-fed controls. Vitamin B1 deficiency of 4 weeks' duration could augment the activity of glycolate oxidase only, with no alterations in the glycolate dehydrogenase and lactate dehydrogenase levels. Intestinal oxalate uptake studies revealed increased bio-availability of oxalate from the gut in vitamin-A- and vitamin-B6-deficient rats. Thus, the results suggest the relative contribution of both exogenous as well as endogenous oxalate in the process of calculogenesis under various nutritional stress conditions in rat.

Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D014802	Vitamin A Deficiency	A nutritional condition produced by a deficiency of VITAMIN A in the diet, characterized by NIGHT BLINDNESS and other ocular manifestations such as dryness of the conjunctiva and later of the cornea (XEROPHTHALMIA). Vitamin A deficiency is a very common problem worldwide, particularly in developing countries as a consequence of famine or shortages of vitamin A-rich foods. In the United States it is found among the urban poor, the elderly, alcoholics, and patients with malabsorption.

D014804	Vitamin B Deficiency	A condition due to deficiency in any member of the VITAMIN B COMPLEX. These B vitamins are water-soluble and must be obtained from the diet because they are easily lost in the urine. Unlike the lipid-soluble vitamins, they cannot be stored in the body fat.

D026681	Vitamin B 6 Deficiency	A nutritional condition produced by a deficiency of VITAMIN B 6 in the diet, characterized by dermatitis, glossitis, cheilosis, and stomatitis. Marked deficiency causes irritability, weakness, depression, dizziness, peripheral neuropathy, and seizures. In infants and children typical manifestations are diarrhea, anemia, and seizures. Deficiency can be caused by certain medications, such as isoniazid.
