The Central Nervous System

In an organotypic culture, an investigation was conducted into combined effects of cyclophosphamide DNA as synthesis inhibitor used to model a resorptive action of mustard gas, and cortexin polypeptide or each of 20 encoded amino acids on the development of cell proliferation in cerebral cortex explants of the rat. The combined administration of cyclophosphamide together with cortexin or with each of the 20 encoded amino acids, except glycine, showed suppression of the cytostatic agent inhibitory effect. Thus, cortexin and amino acids have a protective effect on cell proliferation in the tissue culture of the central nervous system under the action of mustardlike substances.

An urgent problem is the search for substances that can provide a protective effect in cases of DNA synthesis and repair disorders that arise as a result of side effects of cytostatic drugs used in the treatment of cancer. The aim of this work was to study the effect of 20 encoded amino acids in the presence of Cyclophosphane on the development of organotypic culture of rat liver tissue. The results obtained indicate that Cyclophosphane; which simulates the action of such cytostatic substances; inhibits cell proliferation in the liver tissue. It was also found that the encoded amino acids: asparagine; arginine; and glutamic acid; eliminate the inhibitory effect of Cyclophosphane in liver tissue culture. The growth zone of explants after combined exposure to Cyclophosphane (whose isolated action suppressed the growth zone) and these amino acids increased significantly and reached control values. Thus; the experimental data create the basis for the development of methods for the therapeutic use of the three studied amino acids for the removal of side effects in the treatment with cytostatic drugs.

The effect of the 20 coded amino acids was investigated on the development of the processes of the proliferation in the organotypic tissue culture of rat skin. The amino acids lysine, arginine and glutamine acid at 0,05 ng/ml concentration stimulated the cellular proliferation in the growth zone of explants by 29-30%. The mustard-like agent cyclophosphane at 1 mg/ml concentration inhibited the cellular proliferation. The delay of this inhibiting effect of cyclophosphane was observed by the combined action of stimulating amino acids with the cyclophosphane. Thus, the amino acids with the charge radicals can be protectors of the cellular proliferation by the toxic effect of the cyclophosphane on the skin. This effect can be used for the treatment of the mustard injury of skin and for the delay of the adverse effect of cytostatic in oncology (1 figure, 1 table, bibliography: 28 refs).

The effect of the 20 coded amino acids was investigated on the development of the processes of the proliferation in the organotypic tissue culture of rat skin and brain cortex. Some amino acids at 0.05 ng/ml concentration stimulated the cellular proliferation in the growth zone of explants. The other inhibited it. The combination of the stimulating and inhibiting amino acids - Leucine with Proline or Tyrosine-, lead to the proliferation stimulation by 24-32%. The mustard-like agent cyclophosphane at 1 mg/ml concentration inhibited the cellular proliferation. However, the delay of this inhibiting effect of cyclophosphane was observed by the using of combination of amino acids with cyclophosphane. Thus, the amino acids can be protectors of the cellular proliferation by the toxic effect of the cyclophosphane on the tissues of the ectodermal genesis. This effect can be used for the treatment of the mustard injury of skin, brain cortex and for the delay of the adverse effect of cytostatic in oncology
