[SOME PECULIARITIES OF SYPHILIS MORPHOLOGY AND PATHOLOGY (REVIEW)].

The aim of the research was to study the pathomorphosis of syphilis under modern conditions. The morbidity, clinical and epidemiological peculiarities of syphilis were analyzed both domestically (in Ukraine) and internationally. It has been established that in the pattern of syphilis morbidity, latent forms vary between 20% and 40%.

Kinetics of photochemical reactions of biphotochromic compounds based on spironaphthopyran and enamine--conjugation effect.

A novel biphotochromic compound (BPC) with two photochromic fragments, namely spironaphthopyran and hydroxyazomethine, was synthesized and studied by nanosecond laser flash photolysis using the excitation wavelengths of 337, 430, 470 and 500 nm in methanol and toluene. The photoexcitation of BPC results in the formation of at least two colored transients. The first one is the merocyanine form B (the maximum in the absorption spectrum is near 600 nm and the lifetime is 0.

[Some indices of congenital and acquired immunity in patients with endogenous diseases of schizophrenic spectrum disorders].

Indices of congenital leukocyte elastase (LE) activity and adaptive immunity (a level of autoantiboies to nerve growth factor--AabNGF) in blood serum of patients with schizophrenia (attack-like, continuous and slow progressive types) and schizoaffective psychosis have been compared with clinical presentations of the disorders. A patient's state was assessed by clinico-psychopathological methods and with the Positive and Negative Syndromes Scale (PANSS). All schizophrenia types and schizoaffective psychosis were accompanied by LE activity elevation.

The effect of dietary n-3 polyunsaturated fatty acids on HDL cholesterol in Chukot residents vs muscovites.

Native Chukot Peninsula residents, in contrast to Muscovites, consume a diet rich in n-3 polyunsaturated fatty acids. This dietary peculiarity is reflected in differences in plasma lipid and apolipoprotein contents. The Chukot residents have lower contents of total cholesterol, triglyceride, LDL (low density lipoprotein) cholesterol and apolipoprotein B, but higher HDL (high density lipoprotein) cholesterol levels than do Muscovites.

Flow cytofluorometric study of lipoprotein interactions with cultured endothelial cells.

Accumulation of rhodamine B isothyocyanate-conjugated low density lipoproteins (R-LDL) in cultured endothelial cells from human umbilical cord was studied with a fluorescence activated cell sorter. R-LDL uptake was blocked at 0 degrees C, inhibited by addition of excess of nonlabeled low density lipoprotein, high density lipoprotein-2 or high density lipoprotein-3. High density lipoprotein-2 was about twice as effective in inhibition of R-LDL uptake as high density lipoprotein-3.
