Epoxy Nanocomposites with Carbon Nanotubes Produced by Floating Catalyst CVD.

Epoxy nanocomposites with float catalysis-produced CNT felt as a filler were prepared. Parameters such as the curing process, glass transition of epoxynanocomposites, structure and morphology of CNT felt, initial epoxy composition, and epoxy nanocomposites were investigated. The influence of CNT felt on curing process in epoxy nanocomposites with different amounts of curing agent was determined.

[Improving the efficacy of tuberculosis immunodiagnosis using anti-human IgG monoclonal antibodies].

Monoclonal antibodies (MAb) F5 to human IgG were used for creating immunoperoxidase conjugate. MAb dissociation constant was 10(-9)M-1 and the number of binding sites 1. Enzyme immunoassay (EIA) and immunoblotting showed that MAb F5 specifically recognize conformation epitope on intact human IgG molecule but not on other human immunoglobulins or denatured IgG.

[Serological and immunochemical properties of carbohydrate-containing fraction from mycobacterium tuberculosis H37Rv].

Using affinity chromatography on concanavalin A (Con A) sepharose CL 6B, a carbohydrate-containing fraction was derived from Mycobacterium tuberculosis H37Rv sonicate. Surprisingly, the main component of Con A fraction was a protein having a molecular weight of a 30-kD range which is generally absent in the Con A-adsorbed fraction from the culture filtrate. ELISA by means of an antimycobacterial monoclonal antibody panel showed that the 30-kD range of Con A fraction contained antigen 85.

[Comparative analysis of two mycobacterium tuberculosis antigens and two methodological approaches to determining serum antimycobacterial antibodies].

The glycoprotein (15-18 kDa) antigen of Mycobacterium tuberculosis H37Rv was affinity isolated on the immunosorbent with monoclonal antibodies S4C1G4 (specific to M. tuberculosis H37Rv; Avdiyenko V. G.

[Systematic approach to detection of anti-idiotypic antibodies to antimycobacterial idiotype in man and animals].

ELISA in the sandwich modification was developed to detect anti-idiotypic antibodies to the antituberculosis idiotype of monoclonal antibodies (MAb) S4C1G4 (anti 15-18 kDa H37Rv). Sera immunoglobulins were determined by Staphylococcus protein A capture. F[ab+]2, the MAb fragments S4C1G4 (IgG2a, kappa) and 1.

[Lipid peroxidation and various parameters of mineral metabolism in patients with alimentary obesity during therapy with monosodium glutamate].

Lipid peroxidation and mineral metabolism were studied in patients with III degree of obesity and bad standing of sodium restricted diet before and after treatment with including in diet of monosodium glutamate (MSG). It was established well being of MSG and absence of negative effect on loss of body mass in course of dietary treatment. MSG caused normalization of level of diene conjugates and some minerals in serum of patients.

[An experimental analysis of Mycobacterium smegmatis as a possible vector for the design of a new tuberculosis vaccine].

This study was inspired by WHO program for vaccine development. Our experimental model of lethal tuberculosis in mice was used to test whether rapidly growing avirulent M. smegmatis could be used as a live vaccination vector for screening rationalized M.

[An analysis of the specificity of anti-Mycobacterium monoclonal antibodies and of the chemical nature of the antigenic determinants with which they react].

Seven hybridomas of BALB/c mice producing monoclonal antibodies (mAb) against M. tuberculosis H37Rv have been obtained. The mAb acted against M.

[Effect of atherosclerotic diet containing polyunsaturated omega-3 fatty acids on level of natural antibodies to prostaglandin F2alpha in patients with ischemic heart disease, hyperlipidemia and hypertension].

The hypolipidemic, antiatherogenic and thrombolytic effects and decrease of prostaglandin F2 alpha (PG) excretion were observed in 55 patients suffering from Ischemic heart disease, hyperlipidemia and hypertension fed the antiatherosclerotic diet containing 20 g of eiconol during 55 days. The low initial level of natural antibodies to PGF2 alpha was increased significantly in blood serum. Authors consider that decrease of PGF2 alpha level under diet influence is connected not only with the change of fatty acid composition of cell membranes but also with increasing of natural antibody production.

[Morphologic changes of peripheral lymphoid tissue and liver in experimental animals under food deprivation].

Morphologic examinations of liver, spleen, mesenteric lymph nodes and groups of lymphatic follicles of small intestine (Peyer's patchs) of rats in condition of starvation were shown. Starvation of animals for 48 hours and most for 96 hours was caused statistic reliable decrease of body mass, concerning mass of thymus and liver. Centrolobular fatty infiltration and decrease of RNA and glycogen contents in hepatocytes of liver were shown.

[Characteristics of anaphylaxis in fasting rats].

The effect of 4-day fasting was studied in male Wistar rats (200-150 g) sensitized by ovalbumin on anaphylaxis manifestations in vivo, antigen-dependent histamine secretion by mast cells in vitro, concentration of serum specific IgG antibodies. The fasting ended by a shocking allergen dose. It is shown that in the condition of food deprivation anaphylactic severity significantly lowered as well as antigen-dependent histamine secretion by mast cells.

[The effect of starvation on mast cell functional activity and on the content of microsomal cytochromes in the liver].

Histamine secretion and ATP levels were measured in mast cells from the abdominal and pleural cavities of Wistar rat males (250-300 g) which had been starving for 2-4 days. Food deprivation had no effect on histamine levels and secretion in exposure to substance 48/80. ATP concentration got reduced from starvation day 2.

[A hygienic evaluation of the new flocculant polyhexamethyleneguanidine].

Sanitary and toxicological study of some guanidine containing polymers was done. Moderate toxicity of the polymers and absence of any specific effects were noted.
