It has been found that a single interperitoneal injection of mice with NKLy ascite lympholeucosis cells and Bacillus intermedius RNAse or its derivative, obtained in result of activation of the active centre, on histidine ...

Pancreatic RNase modified by the surface active substance oxanole KD-6 (OxRNase) was studied in respect to its cytotoxic action on cells. The studies included in vitro and in vivo tests with intravital staining of the cells ...

By using a rosette formation test the effect of ribonuclease Bacillus intermedius (RNase Bi) on T- and B-lymphocytes in human peripheral blood has been studied in vitro. The RNase effect on T-lymphocytes depends on its ...

It has been demonstrated for the first time that the toxic effect of 2,4,6-trinitrotoluene on the gram-positive strain Bacillus subtilis SK1 is accompanied by a decrease in the cell size and an increase in the refraction ...

The toxic effect of high (200 mg/l) 2,4,6-trinitrotoluene (TNT) concentrations on Escherichia coli K12 cells in the absence of exogenous nutrient sources (incubation in 0.5% NaCl) was shown to manifest itself in the transfer ...

The interactions between rat peritoneal macrophage and Bacillus intermedius dimer RNase cross linked by dimethylsuberimidate was investigated in vitro. It has been found that dimer in the form of RNase at concentrations ...

Medical or occupational exposure of patients and healthcare personnel to ionizing radiation (IR) can be a cause of genetic disorders. In this article we discuss the efficiency of the following tests used to comprehensively ...

Conditions for modification of Bacillus intermedius ribonuclease with dialdehyde dextran was optimized by Box and Wilson's method to achieve the enzyme with higher activity. The generalized parameter including the yield ...

The sensitivity of Escherichia coli strains K-12 and 055 to 2,4,6-trinitrotoluene (TNT) was found to correlate with the structural and functional properties of the outer lipoprotein membrane. The protective ability of the ...

Using Bacillus subtilis SK1 as an example, it was demonstrated for the first time that 2,4,6-trinitrotoluene (TNT) transformation pathways change with TNT concentration. The growth of cultured B. subtilis SK1, delayed at ...
