The main purpose of this paper is to study the possible causes of blood-brain barrier (BBB) damage during the acute condition of schizophrenia (Sch), which makes brain antigens accessible to the immunocompetent cells. The development of autoimmune reactions in this disease has to be preceded by the damage of BBB. We have studied the level of activity of… (More)
This review considers the data of recent years concerning the contact system initiating the activation of blood plasma proteolytic systems, such as hemocoagulation, fibrinolysis, kininogenesis, and also complement and angiotensinogenesis. The main proteins of the contact system are the factors XII and XI, prekallikrein, and high-molecular-weight kininogen.… (More)
A 3000--6000-fold purified kallikrein was obtained from human serum in 10--25% yield by chromatography on QAE-Sephadex A-50, Molselect CM-50 and on soybean trypsin inhibitor (SBTI)-AH-Sepharose 4-B. The enzyme had a specific activity of 14--23 U, as measured by BAEE hydrolysis. Some properties of highly purified kallikrein are described.
The large number of components of the kallikrein-kinin system (KKS) and multifunctionality of the system as a whole and that of each of its components enable its participation in the processes of adaptation and organism defense, as well as in many other physiological and pathological states, and serve as the main reasons for unfailing interest in this… (More)
It is commonly known that activation of plasma kallikrein-kinin system is of great importance in the pathogenesis of atopic diseases. Plasma kallikrein most likely activates other arginine-esterases in human plasma. Diagnostic and prognostic values of the total arginine-esterase activity and the activity of leukocyte elastase (LE) in plasma of patients with… (More)
We are concerned with the investigation of dynamics of the plasma kallikrein-kinin system, elastase-like activity and some serpins, alpha 1-protease inhibitor, alpha 2-macroglobulin and antithrombin III, in patients suffering from general peritonitis and chronic renal failure. The results indicate that activation of the kallikrein-kinin system, as well as… (More)
It is thought that dystrophic changes in the human aging anterior eye are due to lipid peroxidation in both the cortical and nuclear structures of the lens under the conditions of ischemia. These changes are often accompanied by only lens opacification (senile cataract-SC) or by formation of amorphous or fibrillar deposits in anterior eye, disturbances of… (More)
