A new generation of synthetic carbon adsorbents was used in production of deliganded human serum albumin preparation. Thermal effects of officinal and deliganded albumin interaction with specific chemical markers were analyzed by flow microcalorimetry. The results demonstrated a 2.5-fold increase of the complexing ability for the deliganded one. The detoxifying potentials of deliganded albumin were studied in comparison with officinal preparation in rats with burn toxemia after IIIB-IV degree thermal injury and in model experiments with blood serum of patients after severe thermal burn. The transfusion of a 5% officinal albumin solution in rats 1 h after burn trauma resulted in a decrease of serum and liver cytosols cytotoxicity 2.2 and 2.4 times, respectively, in comparison with those of burned rats. After deliganded albumin transfusion the cytotoxic activity of blood serum dropped 8.5 times and that of the liver cytosols 18.5 times. The incubation of blood serum of injured patients with equal amounts of a 5% solutions of officinal or deliganded albumin resulted in a fall of the cytotoxicity level and the growth of binding ability. A comparative analysis of detoxifying potentials of albumin preparations has unambiguously demonstrated deliganded albumin advantages.
新一代合成碳吸附剂被用于制备去配体人血清白蛋白制剂。采用流动微量热法分析了药用白蛋白和去配体白蛋白与特定化学标记物相互作用的热效应。结果表明,去配体白蛋白的络合能力提高了2.5倍。在III B - IV度热损伤后的烧伤毒血症大鼠以及严重热烧伤患者血清的模型实验中,对比研究了去配体白蛋白与药用制剂的解毒潜力。烧伤创伤后1小时给大鼠输注5%的药用白蛋白溶液,与烧伤大鼠相比,血清和肝细胞溶质的细胞毒性分别降低了2.2倍和2.4倍。输注去配体白蛋白后,血清的细胞毒性活性下降了8.5倍,肝细胞溶质的细胞毒性活性下降了18.5倍。将等量的5%药用或去配体白蛋白溶液与受伤患者的血清一起孵育,导致细胞毒性水平下降和结合能力增强。白蛋白制剂解毒潜力的对比分析明确显示了去配体白蛋白的优势。
