| Abstract: | Summary Chromolipoid pigments prepared in vitro were found to be a mixture of compounds of different degrees of polymerization and different histochemical characteristics. Some fractions give positive Feulgen nucleal reaction, stain with methyl-green and absorb ultraviolet light, thus closely mimicking DNA. Ways of differentiating such chromolipoids from DNA are pointed out.Similar chromolipoids have been produced in rats by injecting subcutaneously cod liver oil, or by chronic poisoning by lead.With 4 Figures in the Text, of which 2 in ColourThis study is part of a thesis submitted by Mr.S. Shoshan to the Hebrew University Hadassah Medical School in partial fulfilment of the requirements for the title of Master of Medical Sciences. |
