Objective
 The aim of this study was to compare four commonly
 used cytotoxicity assays (XTT, neutral red uptake, crys-
 tal violet assay, and propidium iodide staining) which
 analyzed the antiproliferative effects vitamin K2.
 Material Method
 Saos-2 cells, an osteosarcoma cell line, were
 exposed K2 at different concentrations (10
 μM, 20 30 40 50 100 ...

The relevance of this paper is that transfusion allogeneic blood to recipient animals always associated with immunological risks. In regard, the purpose study was assess state phagocytic activity neutrophils by indicators index, number, and oxygen-dependent bactericidal activity, as well establish changes in antibody-dependent cytotoxic lymphocytes rabbits during whole transfusion. Modelling tr...

Waste tires from traffic are a well-known environmental problem today. For this reason, the toxicity and potential biodegradation of crushed were tested in respiration test with microorganisms. A non-specific soil microbial community was used. Two experimental designs their effect on results compared—a eluate contact test, i.e., solution containing tire particles during test. The consumption di...

The aim of our study was to determine the phagocytic activity leukocytes and nitrosine tetrazolium test (NST - test) in dynamics experimental periodontitis (EP) immobilization stress (IS). It is established work that indicators studied by us, namely number, index NST increase on 3 rd, 5 th 15 days experiment. above tests have a high diagnostic value allow characterize degree inflammatory proces...

The adaptation of a tetrazolium salt assay for serum lactate dehydrogenase to full automation is described. The tetrazolium salt, INT, (2-p-iodophenyl-3-p-nitrophenyl5-phenyl tetrazolium chloride) serves as the chromogenic indicator of the enzyme activity. Phenazine methosulfate serves as an intermediate electron carrier. Estimation requires only 5 mm. of incubation, and assays may be run at th...

Abstract: Asymbiotic germination techniques are successful in species of the Catasetum genus. The diverse composition culture media can be critical; however, viable seeds required for asymbiotic germination. reliable method viability assessment is tetrazolium test. A decisive step efficiency test preconditioning with sucrose solution, which has potential to improve Therefore, this work aimed ev...
