JOURNAL FREE ACCESSAs described previously [Vitamins (Japan), 61, 93 (1987)], thiamine causes cytochrome deficiency and hence respiratory depression through vitamin B_6 deficiency in the cells of Saccharomyces yeasts. The cytochrome deficiency caused also alteration in lipid composition in S. carlsbergensis. Unsaturated fatty acid content was decreased and sterol composition was changed in the cells grown with added thiamine without supplementation of vitamin B_6, as expected from the participation of microsomal cytochromes in lipid metabolism. The effects of thiamine-induced cytochrome deficiency on lipid composition were abolished by concomitant addition of pyridoxine as in the case of respiratory depression.View full abstractDownload PDF (774K) -

JOURNAL FREE ACCESSBioavailabilities of vitamin A and E were examined in six healthy adult volunteers after daily administration of a multivitamin preparation including 4,000 IU of retinyl palmitate and 20mg of dl-α-tocopheryl acetate for 7 days. Daily changes in plasma retinol levels were shown by approximately 10% elevation from the baseline level after 7 days administration, while there were no significant changes were observed in both plasma retinol and tocopherol levels during 24 hours after the administration. A vitamin E preparation (100mg of d-α-tocopheryl acetate) was once administered in three volunteers at 7 days interval after administration of multivitamin preparation. An elevation of plasma a-tocopherol level (150% of baseline level) and a decrease of plasma γ-tocopherol level were documented at 10-12 hours.View full abstractDownload PDF (579K) -

JOURNAL FREE ACCESSPlasma levels of 25-hydroxyvitamin D_3 (25-OH-D_3) and 1α,25-dihydroxy-vitamin D_3 [1,25-(0H)_2-D_3] of healthy subjects in Akita were determined to investigate the antirachitic activity of sun light and the nutritional problems of vitamin D_3. The results are summarized in the following: (1) Plasma levels of 25-OH-D_3 of healthy subjects in Akita were 23.2±8.1 (M±SD)ng/ml, and these in summer were higher than those in winter. It showed the age variation that the levels in the forties and fifties were significantly higher than those in the subjects of under twenties. (2) Plasma levels of 1,25-(OH)_2-D_3 of healthy subjects in Akita were 49.0±17.9pg/ml, which did not show significant difference among sexes, seasons and generation. (3) The plasma levels of 25-OH-D_3 and 1,25-(OH)_2-D_3 in Akita were not significantly different from the respective data in Hanshin area.View full abstractDownload PDF (843K) -
