AbstractThe effect of photoinduced enhancement of Evans blue (EB) dye fluorescence in blood plasma and albumin solution has been considered. Manifestations of the dye fluorescence enhancement in the albumin solution and rat blood plasma have been compared. Saturation of photoinduced fluorescence, the effect of enhanced fluorescence delay, and divergence in fluorescence spectra of the solutions have been found for the first time. Based on the obtained results, a hypothesis about the presence of nonfluorescent complexes with the EB participation in blood plasma is proposed.

Background. Change of the content of sulfur-containing amino acids and their metabolites is one of the pathochemical mechanisms of alcohol intoxication. Purpose of the study. To study the effect of chronic and intermittent alcohol intoxication on the content of sulfurcontaining amino acids and related compounds in the rat blood plasma. Material and methods. Thirty white outbred rats weighing 180-220 g. The content of free amino acids and biogenic amines was determined by HPLC. Results. A 14-day chronic alcohol intoxication was accompanied by a significant decrease in the level of methionine and an increase in the level of homocysteine in the blood plasma. The concentration of glutathione increased by 5%. In the intermittent alcohol intoxication IAI-4 group, the homocysteine content also increased, as did the level of homoserine and cystathionine in the IAI-1 group. Conclusions. Сhronic and intermittent alcohol intoxications cause similar violations of the level of sulfur-containing amino acids and their metabolites in the rat blood plasma.

The activity of the angiotension -converting enzyme (ACE) in human, dog, rabbit, and rat blood plasma was assayed by spectrofluorometric determination of the product liberated by enzymatic cleavage (L-His-L-Leu). In parallel experiments the hydrolysis of L-His-L-Leu by blood plasma was examined. The hydrolytic activity of rat blood plasma was high and therefore lower values of ACE activity were obtained; the use of the spectrofluorometric assay with rat blood plasma is therefore problematic. By contrast, L-His-L-Leu was not degraded by human, dog, and rabbit blood plasma and the spectrofluorometric determination of this peptide can thus be used to advantage to assay the ACE activity of blood plasma samples of these species.
