Benzen (BZ) is a ubiquitous environmental pollutant with a toxic effect mainly aimed at the hematopoietic and immune systems. Atriplex halimus L. (Amaranthaceae) is a Mediterranean halophytic shrub traditionally used in North Africa as medicinal plant for several therapeutic uses. The present study aimed to estimate the preventive and curative effects of Atriplex halimus L. (Ah) aqueous extract against BZ-induced hematotoxicity in rats. Analysis of the extract by the method of LC-MS revealed the presence of 7 vitamins, among which vitamin C content was the highest. Adult rats were divided into five groups as follow: Group 1 received water (control); Group 2 received orally Ah aqueous extract (200 mg/kg) 3 days/week for 15 weeks; Group 3 received BZ (100 mg/kg b.w) daily in drinking water for 15 weeks; Group 4 received concomitantly BZ (100 mg/kg) and preventive treatment with Ah (200 mg/kg) for 15 weeks (AhP+BZ); Group 5 first received BZ (100 mg/kg) for 11 weeks and then curative treatment with Ah extract (300 mg/kg) daily for 30 days (BZ+AhC). It was shown that sub-chronic exposure to benzene induced leukopenia, lymphocytopenia, granulocytopenia and massive degeneration of the bone marrow tissue. The level of GSH and activity of GST and CAT were significantly lowered and the level of MDA was increased in the blood and bone marrow in rats of BZ-intoxicated group compared to the control rats. Administration of Ah extract recovered the bone marrow structure, dramatically decreased MDA content and increased GSH and CAT activity and GST level in the blood and bone marrow as compared with the indices in BZ-treated group. These observations demonstrate that curative and, to a lesser extent, preventive treatment with Atriplex halimus extract have therapeutic potential against hematotoxicity induced by benzene.

Biochemical characteristics of kidneys, peripheral blood and bone marrow of rats in model of tumor growth under introduction of cisplatin and cis-tetrachlorodi-μ-isobutyratodirhenium(III), cis-Re2(i-C3H7COO)2Cl4 (I) have been investigated. It was shown that introduction of I alone and together with cisplatin led to decrease of biochemical markers of oxidation of lipids and proteins in tissue homogenates of the kidneys, change of enzyme activity in the urea and tissue homogenates of the kidneys, by a decrease of filtration function of kidneys. Introduction of nanoliposomal forms of the rhenium cluster compound led to a practically normal morphological picture of bone marrow and increase of the RBC (by 60%) with normalization of hematocrit counts, and decrease of quantities of destructed RBC (3.2 times) in comparison with the tumor-bearing animals. A tentative scheme of influence of cluster rhenium compound on erythropoiesis through regulation of synthesis of erythropoietin in kidneys has been proposed.
