ABSTRACT
From the positive effects of the drugs prepared from various parts of walnut described for a wide variety of diseases, their antitumor effect is remarkable. This feature can be used for treatment of leukopenia caused by radiotherapy and/or chemotherapy. Therefore, to study the immunocorrective properties of Greek walnut, the walnut septa were selected, aqueous extract of which has been studied on experimental model of leukopenia in white mice caused by a single injection of cyclophosphamide. The material of the study were the blood and bone marrow smears from intact and tested adult mice stained by Giemsa's dye. The quantity of leukocytes in peripheral blood were determined by the counting chamber under the light microscope with standard protocol. Cloud-point extraction, HPLC analysis and UV-visible spectrophotometry were used to study the composition of the walnut septa extract. It has been established that the Greek walnut septa extract has the correction ability of suppressed myelopoiesis in white mice caused by injection of cyclophosphamide. The blood formula normalization process by the mentioned extract is provided by the fast increasing in number of immature (band neutrophil) and mature neutrophils in the peripheral blood. It was shown that walnut septa extract stimulates the division, differentiation and maturation of blast forms of myeloid as well as lymphoid line in the bone marrow of mice with leukopenia. Cloud-point extraction and liquid-chromatographic analysis revealed the presence of hydrophilic and hydrophobic components in the walnuts septum extract.
