Abstract
Seventy-nine adults were examined with a few diurnal and seasonal repeats showing no significant changes with regard to vitamin A.In males an average of 60.4 μg/100 ml of vitamin A was found expressed as axerophtol, the coefficient of variation being 22.4 per cent. In females corresponding figures are 49.9 μg/100 ml and 27.3 per cent.Carotene mean was 59.6 μg/100 ml for men with actual ranges observed 21–123, and 71.6 μg/100 ml for women, ranges 30–143.In males vitamin A is significantly higher and carotene is on the average slightly lower than in females.Influence of age is discussed with no certain trend either for vitamin A or for carotene.The results are compared with other studies and it is concluded that axerophtol values in the present material largely correspond with results found in recent studies from other countries.
