[Assessment of body intoxication as a balance between accumulation and binding of toxin in plasma].
A novel approach to assessing endogenic intoxication (EI) as an imbalance between toxin accumulation and binding by albumin in blood plasma is proposed. The intoxication criterion (IC) is determined by the ratio of the content of medium-weight molecules (MWM) and effective albumin concentration (EAC): IC = MWN/EAC. In children with oncohematological diseases the development of EI is associated with a 4-fold drop of MWM content and a twofold decrease of EAC, and hence, the imbalance between these two values increases 9-10 times. The proposed approach notably improves the sensitivity of diagnosis of the early stages of EI. Application of a new fluorescent marker pirrone red for measuring albumin binding capacity is validated and an algorithm of EAC determination using calibration curve of probe binding to standard albumin solution is described.
