[The effect of dietary proteins on the fluorescence of Nile red in the aortic arch in guinea pigs].
The purpose of the paper was to investigate the effect of soy and casein protein, present in the diets in various ratios, upon cholesterolemia and intensity of Nile red fluorescence (as indicator of lipoproteins) from the wall of the arch of aorta in guinea pigs. A special optoelectronic device was constructed to allow objective quantitative measurement of fluorescence from histologic sections. Administration of soy protein, compared to cassein protein, resulted in significantly lower cholesterolemia values and lower fluorescence intensity. The study has verified the effect of the two dietary proteins tested also at the level of the vessel wall.
