[Effect of a diet containing calcium pantothenate on urinary vitamin excretion and on the liver and kidney total pantothenic acid level in rats].

Four groups of five adult rats weighing 310 g received during 20 days a diet containing 0, 1.68, 16.8 or 168 mumol of pantothenic acid per kg of diet. The daily urinary vitamin excretion was, in nmol per day: 32 +/- 8, 32 +/- 4, 180 +/- 23 and 2,100 +/- 91, respectively (mean +/- SEM). Liver and kidney pantothenic acid content was the same in all groups, in nmol per g of fresh tissue: 300 +/- 36 and 190 +/- 6, respectively (mean +/- SEM, n = 20).
