- Study of the memory of rats after administration of Sudan Yellow 3 G
- Study of the memory of rats after administration of Sudan Yellow 3 G. Majlathova, M. (Lek. Fak., Univ. Komenskeho, Martin, Czech.). Bratisl. Lek. Listy, 66(4), 416-20 (Slovak) 1976. CODEN: BLLIAX. DOCUMENT TYPE: Journal CA Section: 17 (Foods) Section cross-reference(s): 40, 4 After 100 days of spontaneous feeding on a diet colored by 1% and 0.1% Sudan Yellow 3G [4314-14-1], male rats were tested on the 103rd and the 104th day. The duration of their stay in a small dark space and in a large illuminated space was detd. in 3-min intervals. After an elec. shock in the small space, the duration of stay of each rat was followed for 3 min in the course of 14 days. The statistical evaluation of the duration of the stay of exptl. and of control rats revealed that the differences in the duration of stay in the large space were incidental and the dye under study does not affect the memory of rats.
- Study of the p-electron structure and possible azo-hydrazone tautomerism of some hydroxyazo dyes
- Study of the p-electron structure and possible azo-hydrazone tautomerism of some hydroxyazo dyes. Simov, D.; Stoyanov, S.; Tomov, S. (Dep. Org. Chem. Technol., Sofia Univ., Sofia, Bulg.). God. Sofii. Univ. "Kliment Okhridski", Khim. Fak., Volume Date 1979-1980, 74, 155-65 (Bulgarian) 1984. CODEN: GSKFAL. ISSN: 0584-0317. DOCUMENT TYPE: Journal CA Section: 41 (Dyes, Organic Pigments, Fluorescent Brighteners, and Photographic Sensitizers) The electron spectra and p-electron structure of azo dyes 4-(phenylazo)-1-naphthol [3651-02-3], 1-(phenylazo)-2-naphthol [842-07-9], a-(phenylazo)acetoacetanilide [94317-76-7] and 3-methyl-1-phenyl-4-(phenylazo)-5-pyrazolone [4314-14-1] and the azo-hydrazone tautomerism were studied. The coloristic properties of all dyes were directly related to their tautomerism. The long-wave p-electron transition accompanied by intramol. charge transfer in opposite directions for resp. azo and hydrazone tautomers was proven by quantum chem. calcns.
