Colour Reactions Attributed to Vitamin A

Acute adverse reactions attributed to allopurinol in hospitalised patients.

Of 29 524 hospitalised medical patients monitored in a drug surveillance programme 1835 (6.2%) received the xanthine oxidase inhibitor allopurinol. After the exclusion of skin reactions adverse effects were attributed to this drug in 33 (1.8%) patients, the most frequent being haematological abnormalities (11 patients, 0.6%) and diarrhoea and drug fever (5 each, 0.3%). Adverse effects were dose...

Colour vision in vitamin A deficiency

suggests, as do our data, that responses to 1-x-OHD, and I-ax, 25-(OH)2D, are different enough to have important implications in treatment. Although hypercalcaemia remains a serious risk with all vitamin D derivatives the rapid reversal that is possible after I-x, 25-(OH),D, treatment makes this agent preferable to calciferol and possibly to 1-x-OHD,. This is particularly so in patients in whom...

Activity ratio of adrenaline to noradrenaline in various colour reactions.

Toshiyuki Ozaki (尾 崎 俊 行) From the Department of Physiology, Nagasaki University School of Medicine, Nagasaki (Received for publication, March 1, 1955) In estimating adrenaline content of the adrenal medullary tissue or of the adrenal venous blood, various colour reactions have been applied, ad renaline being used as the reference standard. However, it is generally accepted that noradrenaline i...

Colour-Temperature Correspondences: When Reactions to Thermal Stimuli Are Influenced by Colour

In our daily lives, information concerning temperature is often provided by means of colour cues, with red typically being associated with warm/hot, and blue with cold. While such correspondences have been known about for many years, they have primarily been studied using subjective report measures. Here we examined this correspondence using two more objective response measures. First, we used ...
