Abstract
Relationship between changes in the erythrocyte sedimentation rate in rats and concentration and charge of polyelectrolyte microcapsules was studied by the Panchenkov method. Positively charged microcapsules reduced erythrocyte sedimentation rate in a concentrationdependent manner. This effect was related to a decrease in the content of high-molecularweight proteins in the plasma due to their adsorption in positively charged microcapsules with polyacrylamide surface layer.

Abstract
Fluorescent and optical spectroscopy were used to study the interaction of alcohol dehydrogenase (ADH) with negatively charged polystyrene sulfonate (PSS) and dextran sulfate (DS), as well as positively charged poly(diallyldimethylammonium) (PDADMA). As found, DS and PDADMA did not affect the structural and catalytic enzyme properties. In contrast, PSS slightly decreased the protein self-fluorescence over 1 h of incubation, which is associated with partial destruction of its quaternary (globular) structure. Investigation of the ADH activity with and without PSS showed its dependency on the incubation time and the PSS presence. Sodium chloride (2.0 M and 0.2 M) or ammonium sulfate (0.1 M) added to the reaction mixture did not completely protect the enzyme quaternary structure from the PSS action. However ammonium sulfate or 0.2 M sodium chloride stabilized the enzyme and partially inhibited the negative PSS effect.

Abstract
Microencapsulated heat shock proteins HSP 70 were studied in terms of their effects on neutrophil apoptosis, production of reactive oxygen species, and secretion of TNF-α by human neurtrophils and monocytes. Encapsulated HSP70 inhibited neutrophil apoptosis by 65% as compared to the effect of nonencapsulated HSP70; TNF-α production by the promonocytic THP-1 cells was similarly inhibited by the non-encapsulated and encapsulated HSP70. Thus, the polyelectrolyte micromolecules can be used as containers for effective delivery of HSP70 up to neutrophils and monocytes to correct the innate immunity functions.

Abstract
The functional state of three proteins of different molecular weight (urease, lactate dehydrogenase, and hemoglobin) in the presence of the linear polyelectrolytes poly(allylamine hydrochloride) (PAA) and sodium poly(styrenesulfonate) (PSS) in the dissolved state and of the same polyelectrolytes bound to the surface of microspheres has been investigated. Microspheres were prepared by consecutive absorption of oppositely charged polyelectrolytes so that the outer layer of the shell was PAA for the acidic protein urease, and PSS for the alkaline proteins LDH and hemoglobin. It was shown that the dissolved polyelectrolyte completely inactivates all three proteins within one minute with a slight difference in the time constant. (By Hb inactivation are conventionally meant changes in the heme environment observed from the spectrum in the Soret band.) In the presence of microspheres, the proteins were adsorbed on their surface; in this case, more than 95% of the activity was retained within two hours. The proportion of the protein adsorbed on microspheres accounted for about 98% for urease, 72% for Hb, and 35% for LDH, as determined from the tryptophan fluorescence data. The interaction of hemoglobin with another type of charged colloidal particles, phospholipid vesicles, leads to the destruction of the tertiary structure of the protein, which made itself evident in the optical absorption spectra in the Soret band, as well as the spectra of tryptophan fluorescence and circular dichroism. In this case, according to circular dichroism, the percentage of alpha-helical structure of Hb was maintained. The differences in the physical and chemical mechanisms of interaction of proteins with these two types of charged colloidal particles that leads to differences in the degree of denaturing effects are discussed.

Abstract
The temperature stability of the cytoplasmic enzyme of the glycolysis of lactate dehydrogenase from a pig muscle (isoenzyme M4) in a complex with the anion polyelectrolyte poly(styrenesulfonate) has been investigated by the methods of adiabatic differential scanning microcalorimetry, the own protein fluorescence, and circular dichroism. Calorimetric investigations of complex of lactate dehydrogenase with poly(styrenesulphonate) in 50 mM phosphate buffer at pH 7.0 have shown that the temperature of the transition and enthalpy of lactate dehydrogenase thermal denaturation sharply decreases with growing weight ratio poly(styrenesulphonate)/lactate dehydrogenase, though at 20 degrees C the enzyme activity of lactate dehydrogenase remains unchanged for several hours irrespective of the addition of poly(styrenesulphonate). The addition of phosphate ions to the solution enhances the resistance of lactate dehydrogenase to both thermal denaturation and inactivation by polyelectrolyte. The data obtained are interpreted from the viewpoint of a special role of two anion-binding centers in intersubunits contacts of lactate dehydrogenase, which enhance its resistance to both thermal denaturation and destruction by polyelectrolyte.

Abstract
The incapsulation of proteins into polyelectrolyte microcapsules (PE-microcapsules) has been studied with the aim to develop microdiagnostica for the presence of low-molecular-weight compounds in native biological fluids. The problem was solved using two enzymes: lactate dehydrogenase and urease. Polyelectrolyte microcapsules were prepared using two polyanions: polystyrene sulfonate (PSS) and dextran sulfate (DS), and two polycations: polyallylamine (PAA) and polydiallylmethylammonium (PDADMA). CaCO3 microspherulites with the incapsulated enzyme served as a "core" in the formation of polyelectrolyte microcapsules. It was shown that the main problem in the preparation of a polyelectrolyte microdiagnosticum is the selection of an oppositely charged pair of polyelectrolytes optimal for the active functioning of the enzyme. It follows from the results obtained that the best polyelectrolyte pairs for the formation of the envelope of a PE-microcapsule are PAA/DS and PAA/PSS for lactate dehydrogenase and PSS/PDADMA for urease. Taking into account these data, we designed enzyme-containing microcapsules with different polyelectrolyte compositions and different numbers of layers and studied their properties.
