Biospecific haemosorbents based on proteinase inhibitor. III. Biospecific antiproteinase haemosorbent 'Ovosorb' in complex therapy of acute destructive pancreatitis.

Analysis was carried out of the results of complex therapy in 32 patients with acute destructive pancreatitis for which haemosorbtion on Ovosorb, a biospecific antiproteinase haemosorbent containing an immobilized ovomucoid, was used. The clinical efficiency of haemosorbtion was displayed as a decrease in gravity of endogenous intoxication and related functional and metabolic disturbances, as well as in a reduction of lethality from 24.7% to 6.2%.

Biospecific haemosorbents based on proteinase inhibitor. II. Efficiency of biospecific antiproteinase haemosorbent 'Ovosorb' in complex treatment of experimental generalized purulent peritonitis and acute destructive pancreatitis in dogs.

The biospecific antiproteinase haemosorbent (BAH) 'Ovosorb' containing, in the bulk of polyacryamide gel, the ovomucoid from whites of duck eggs, was used for a complex treatment of the experimental generalized purulent peritonitis and acute destructive pancreatitis in dogs. The efficiency of BAH was manifested in the significant reduction of lethality of the experimental animals, a more rapid liquidation of proteinasaemia, normalization in plasma of alpha 1-proteinase inhibitor and protein metabolism. Thus, by eliminating proteinases from circulation, Ovosorb contributes to the cessation of imbalance in the proteinase-inhibitor system and is efficient in the therapy of pathological states related to this imbalance.

[The use of a biospecific antiproteinase hemosorbent in the combined treatment of acute destructive pancreatitis]. / Primenenie biospetsificheskogo antiproteinaznogo gemosorbenta v kompleksnom lechenii ostrogo destruktivnogo pankreatita.

Results of treatment of 32 patients with acute destructive pancreatitis are presented. Hemosorption on biospecific antiproteinase hemosorbent "OVOSORB" possessing the property of extraction of the excess of serine proteinases from blood plasma was used. High efficiency of the sorbent for treatment of destructive pancreatitis was shown. This effect was obtained at the expense of correction of hyperproteasemia, normalization of protein metabolism as well as prevention of the production and accumulation of middle molecule peptides possessing various pathological properties in the fluid media of the organism.

The authors examined the efficacy of the biospecific antiprotease hemosorption Ovosorb containing ovomucoid from duck egg protein as part of polyacrylamide gel, which was used in the multimodality treatment for experimental diffuse pyoperitoneum and acute destructive pancreatitis in dogs. Ovosorb effectively diminished proteasemia, restored the plasma inhibitory potential by eliminating dysproteinemia, suppressed the production of secondary peptide endotoxins. These effects of the hemosorbent promoted the regression of endotoxicosis and the significant reduction in experimental animal deaths.

[Treatment of diffuse purulent appendicular peritonitis with antiprotease sorbent "ovosorb"]. / Lechenie razlitogo gnoinogo peritonita appendikuliarnogo geneza s primeneniem antiproteaznogo sorbenta "ovosorb".

The authors studied the character of the therapeutic action of some links of protein metabolism in connection with the use of hemosorption with a biospecific antiprotease hemosorbent "ovosorb" in the complex treatment of 24 patients with diffuse purulent peritonitis of appendicular genesis. It was found that the antiprotease biospecific hemosorbent is marked by high efficacy in the correction of protein metabolism and the consequent systemic disorders in patients with peritonitis of an appendicular genesis. It is shown that "ovosorb" removes selectively from hemocirculation active forms of proteinase of their complexes with inhibitors and, in contrast to carbon sorbents does not possess unspecific sorption of the inhibitors of proteinases and other blood plasms proteins.

[A method of determining middle molecules]. / Sposob opredeleniia "srednikh molekul".

The authors suggest a method for the detection of 'medium molecules' to be used for rapid diagnosis of poisoning. They present their arguments in favor of a higher specificity of this method as against other rapid methods for 'medium molecule' detection in biologic fluids of the body. The authors' data evidence a high correlation between the results of the suggested method and gel filtration technique. The procedure may be used for the rapid diagnosis of peptidemia severity in the patients with grave endogenic intoxication and in cases when endotoxicosis is not the underlying condition.

[Middle molecules--formation and methods of determination]. / "Srednye molekuly"--obrazovanie i sposoby opredeleniia.

Medium molecules have been detected by two methods, gel filtration and screening technique, in patients with diffuse purulent peritonitis and with chronic renal insufficiency. No close correlation between the findings of the two methods has been observed. The results lead to a conclusion that, despite being rapid and simple, the screening method is hardly adequate for cases with endogenous intoxication. Approaches to improvement of this method are discussed.
