[Regulation of safe levels of polychlorinated biphenyls in soil: Russian and international experience].

The article presents data on the levels of soil pollution by polychlorinated biphenyls (PCBs) in different regions of Russia and foreign countries. For the time present proposed regulatory value for the regulation of PCBs in soils of different land uses have been established to be set mainly on the results of the calculations of risk. However used initial values and features of the methodology for calculating determine significant variability of proposed levels of PCBs in soils.

Functional osteoclast attachment requires inositol-1,4,5-trisphosphate receptor-associated cGMP-dependent kinase substrate.

Osteoclast activity is central to balanced bone turnover to maintain normal bone mass. A specialized osteoclast attachment to bone localizes acid secretion to remove bone mineral; in some cases, attachment is functionally impaired despite normal attachment proteins. The inositol-1,4,5-trisphosphate receptor-1 (IP3R1) is an intracellular calcium channel required for regulation of reversible osteoclast attachment by nitric oxide (NO), an important regulator of both normal and pathological bone degradation.

[Autoantibodies to nerve growth factor and astroglial protein S-100 in Rett's syndrome].

The levels of autoantibodies (AAB) to nerve growth factor (NGF) and to S-100 protein were examined in blood of both mentally normal girls and girls with Rett's syndrome (RS). The elevated titer of anti-NGF AAB, but not of anti-S-100 AAB was determined in the blood of patients with RS. There was relative individual stability of anti-NGF AAB level which didn't depend on the stage of the disease.

[Nerve growth factor auto-antibodies in children with various forms of mental dysontogenesis and in schizophrenia high risk group].

The level of autoantibodies (AAb) to nerve growth factor was evaluated in blood serum of 163 children with different forms of mental dysontogenesis of endogenic, residual-organic, psychogenic and deprivative origin. Significant elevation of the level of AAb was found in all forms of psychic dysontogenesis. The most significant elevation of the level of AAb (p < 0.

Changes in the serum levels of autoantibody to nerve growth factor in patients with schizophrenia.

Studies were performed on 54 patients with different types of schizophrenia-paranoid (8), recurrent-progressive (30), and slowly progressive (16), with ICD-10 rubrics F20.00 and F20.01, F20.

[Changes in the level of autoantibodies to the nerve growth factor in the blood serum of schizophrenia patients].

A study was made of 54 patients with different forms of schizophrenia: paranoid (8), shift-like (30), slow-progredient (16). According to ICD-10 the rubrics were: F20.00 and F20.

[An elevation in the level of autoantibodies to nerve-growth factor in the blood serum of schizophrenic children].

The level of autoantibodies (AAB) to nerve growth factor (NGF) was examined in blood of mentally healthy children, children with early children schizophrenia as well as with Kanner's and Asperger's syndromes too. The elevated titer of AAB to NGF was determined in blood of children with acute, active state of disease; meanwhile the same titer wasn't changed in the state of stable remission or steady defective state as compared with control group. The correlation was found between the level of AAB to NGF and the degree of disease progression.
