- AMINO-ACIDS are often mentioned as synergisbic antioxidants. Their mechanism of enhancing the effect, of primary antioxidants can be explained in different ways: by chelation of pro-oxidative metal traces1 and by regeneration of oxidized primary antioxidants2-4. It has also been shown that amino-acids may play the part of synergistic antioxidants as natural constituents of food material5. On the other hand, there is a lack of systematic survey on a more general basis of this effect of amino-acids. Certain results have been published, which, however, refer to special conditions6,7. No data are available on the effect of amino-acids in absence of other anti-oxidative substances. © 1960 Nature Publishing Group.

- HAMSTERS and mice inoculated at birth with tumour viruses have been used in studies of the prophylactic effects of various treatments during the latent period. The incidence of primary tumours in hamsters infected at birth with SV40 is reduced if the virus is inoculated during the latent period1-3. Similar administration of adenovirus type 12 also inhibited the induction of tumours by SV404; this was taken as an indication of a cross-reaction between the tumour-specific transplantation antigens (TSTA) of SV40 and adeno 12 virus tumours. X-irradiated SV40 tumour cells which did not contain infectious virus were also effective in reducing the frequency of primary SV40 tumours when given at various times before tumour development2,5.
