...Richard D. Semba Vitamin A is essential for normal growth, reproduction, immunity, and vision. The characterization of vitamin A spanned a period of about 130 years. During this long, incremental process, there is no single event that can be called the ‘discovery’ of vitamin A. The physiologist...

...Hans K. Biesalski Vitamin D plays an important role in regular bone growth and in adequate function of the innate immune system, including barrier functions of mucous membranes. A sufficient supply during pregnancy and lactation protects the child from infectious diseases. Clinical symptoms...

... nutritionally investigated by applying anthropometric, laboratory and dietary assessment methods. Results: Mean and median serum retinol concentrations (SRCs) were 228 and 218 μg/l, respectively. Mean prevalence of nutritional deficits among children were stunting (23.4%), anemia (57.5%), vitamin A deficiency...

... compared to controls. Mean RP levels appeared higher in familial hypercholesterolemic patients, when compared to controls, with 6 among 22 patients showing clearly high vitamin A levels and 4 borderline values, whereas high triglyceride levels ( > 2 g/l) were detected in only 1 patient. No patients...

Grančičová Selected vitamin (A, C, E, β-carotene) and trace element (selenium, zinc, copper) levels were estimated in the blood of 67 vegetarian nonsmokers aged 34-60 years. The average period of lacto...

...Sadhna Sharma; Harmeet Sidhu; Ravinder Narula; Swam K. Thind; Ravindra Nath The study was conducted to investigate the effect of vitamin A, B 1 and B 6 deficiency on oxalate metabolism in rats. A significant hyperoxaluria was the common observation in all the three vitamin deficiencies (vitamin B 6...

...H.S. Sharma; P. Ghosh; R.R. Shukla; U.K. Misra Generally, protein energy malnutrition is accompanied with vitamin A deficiency. The present study was undertaken to evaluate the importance of the quality and the quantity of dietary proteins on the in vitro secretion and uptake of vitamin...

... acetate decreased with time and increased in unidentified metabolites and retinyl esters. An insignificant amount of radioactivity was found in liver. We conclude from these results that some vitamin A is stored/accumulated in the testes as retinyl esters in order to support the process of spermatogenesis...

...J.O. Olowookere The relationships between the structural integrity and functionality of rat liver mitochondrial membranes, and different levels of dietary protein and vitamin A transportation during protein depletion in animals have been investigated. Although the vitamin A content of the protein...

...Sunethra Atukorala; T.K. Basu; J.W.T. Dickerson The administration of large doses of corticosterone to normal adult male rats resulted in a rapid loss of vitamin A from the plasma, liver, adrenals and thymus. Of the organs studied, the thymus appeared to be the most sensitive to treatment...

...Paul Higueret; Henri Garcin Some aspects of thyroid hormone metabolism were studied in rats on a vitamin A-deficient diet for 7–8 weeks. It was shown that, in deficiency, thyroxinemia, the extrathyroidal thyroxine (T 4 ) pool and the T 4 biological half-life were increased, and the T 4 distribution...
