the total vitamin c content in human plasma is widely accepted as an indicator of the tissue status of vitamin c. a liquid chromatography method with ultraviolet detector (264 nm) for measuring ascorbic acid in human plasma was developed. a c18 reversed-phase column and cetrimide as an ion-pairing agent was employed. ascorbic acid (aa) was measured after reducing l-dehydroascorbic acid to l-asc...

died within a short period of admission to hospital, the tumours being verified post-mortem. In summarizing these findings it would appear that abnormal mental phenomena may be present in certain cases of cerebral tumour without definite localizing signs. In this series no physical signs were apparent in seventeen per cent., and in an additional forty per cent. these signs were vague and indefi...
