[On the applied medicolegal significance of the notion of "medical error"].

The current practice of expertise of the adequacy of organization of the provision of medical aid introduces a new aspect of the notion of "medical error" that is widely employed in medical profession, among lawyers, patients, and their relatives as well as in mass media. The universally accepted meaning of this notion has not thus far been proposed. The authors consider the medico-legal concept of "medical error" reconciling the contradictory opinions.

[The peculiarities of serum levels of S100b protein and antibodies to it in patients with crisis and stable essential hypertension].

The article covers the results of research into the levels of S100b protein and antibodies to it in the serum of patients with crisis and stable essential hypertension. The results show that neutrophic protein dysmetabolism plays an important role in the pathogenesis of hypertonic dyscirculatory encephalopathy and the forming of cognitive disorder syndrome. The data obtained suggest that hypertensive crises lead to pathologic changes in hematoencephalic barrier permeability and the development of autoimmune reactions with participation of neutrophic proteins.

Activity of caspase-3 and content of DNA fragments with sizes 0.2-0.6 kbp and more than 4.

[Protein HLDF and antibodies to it as molecular pathogenetic factors and new markers of acute cerebral blood circulation disturbances].

Clinic-experimental complex investigation and ELISA determination of protein HLDF as also primary antibodies (Abs) to HLDF values in blood and cerebro-spinal fluid (CSF) of patients with hypertensive crises and acute aterotrombotic ischemic stroke were performed. Statistically improved difference in serum HLDF and Abs content in examined patients in comparison with age-matched controls as also significant intergroup's differences in protein and Abs dynamic content were determined. Correlation between content and dynamics of investigated factors in CSF and blood serum with determined clinical and instrumental parameters was revealed.

[Etalon-free laser mass-spectrometry as a new method of the elementary analysis of bone tissue at identification].

The results of an experimental study dealing with the elementary composition of bone tissue by using the method of laser mass spectrometry are described in the paper. The method ensures the quantification of concentration values of all elements from the Mendeleev periodic table that can be made within an extensive dynamic range, which makes it promising in the forensic medical identification.
