Abstract
Astrocytes are considered to be the dominant cell fraction of the central nervous system. They play a supportive and protective role towards neurons, and regulate inflammatory processes; they thus make suitable targets for drugs and supplements, such as polyphenolic compounds. However, due to their wide range, knowledge of their anti-inflammatory potential remains relatively incomplete. The aim of this study was therefore to determine whether myricetin and chrysin are able to decrease chemokine release in reactive astrocytes. To assess the antioxidant and anti-inflammatory potential of polyphenols, human primary astrocytes were cultured in the presence of a reactive and neurotoxic astrocyte-inducing cytokine mixture (TNF-α, IL-1a, C1q), either alone or in the presence of myricetin or chrysin. The examined polyphenols were able to modify the secretion of chemokines by human cortical astrocytes, especially CCL5 (chrysin), CCL1 (myricetin) and CCL2 (both), while cell viability was not affected. Surprisingly, the compounds did not demonstrate any antioxidant properties in the astrocyte cultures.

Abstract
Vitamin E was used as a protection for human lymphocytes in vitro against the toxic effects of dichlorvos, an organic phosphate pesticide. As the markers of the toxic changes in the lymphocytes lysosomes were chosen as a membrane structure, and nucleoli as a structure connected with protein synthesis. The obtained results were compared with the effects obtained previously in analogous studies after intoxication of lymphocytes with lindan and fenarimol. The experiment showed that vitamin E protected the lysosomal membranes more effectively than the nucleolar structure in these cells.

Abstract
Vitamin E (15 micrograms/ml and 60 micrograms/ml) was used for protection of human leucocytes against toxic effects of lindan (150 microM and 200 microM) in vitro. The protective effect of vitamin E manifested itself as maintenance of the phagocytic activity of granulocytes, the value of nucleologram in lymphocytes, and the proportion of euchrysin-negative lymphocytes near the values in controls.

Abstract
Following lindane intoxication in daily doses of 0.1 LD50 during one month (total dose 2.0 LD50) functional changes were noted in granulocytes and structural changes in lymphocytes in peripheral blood of rabbits during 4 months after completion of lindane administration. A significant decrease of the phagocytic activity with a rise in the number of non-phagocytizing granulocytes, quantitative and qualitative changes of nucleoli and lysosomes were found in lymphocytes. The latest effect of lindane is regarded to be a raised number of non-phagocytizing granulocytes 4 months after withdrawal of the pesticide.

Abstract
After lindane administration in daily doses of 0.1 LD50 for one month (total dose 2.0 LD50) changes in the erythrocytes were found persisting for up to 4 months after withdrawal of the pesticide. A significant increase in the number of echinocytes, a greater per cent of reticulocytes, significantly raised level of denatured haemoglobin, and an increased number of erythrocytes of higher sensitivity to oxidating factors in relation to control group was observed.

Abstract
The effect of fenarimol in blood cells and changes in liver and kidneys in rats were investigated. Fenarimol applied in doses 25 mg/ml intragastrically during 5 days, at 24h after the last doses caused functional and structural changes of blood cells and organs. The decreases of osmotic fragility of erythrocytes and phagocytic activity of neutrophils, and the increase of the percentage of lymphocytes without detectable lysosomes accompanied by the minor decrease of the number of blood cells was observed in the peripheral blood. The indistinctness of the structure of the hepatic lobules and of liver laminae and the vacuolized hepatic cells with pycnotic nuclei were visible in the liver. The abnormally enlarged cortical Malphighian++ glomeruli in kidney were found. The observed changes indicate the cytotoxic effect of fenarimol in strongly intoxicated rats. The impaired phagocytic activity of neutrophils may cause the growth of susceptibility to bacterial infection.

Abstract
This study examines the relationship between cell progress into the state of unbalanced growth, hydrolytic enzyme activities and cell survival during the exposure of L5178Y cells to hydroxyurea (HU), excess thymidine (dThR), hydroxyurea with excess of four deoxyribonucleosides (dNR) or excess dTHR with deoxycytidine (dCR). Cell progress into the state of unbalanced growth was measured as cell size, protein/DNA ratio and protein content per cell. Activities of two lysosomal (acid phosphatase, beta-N-acetylglucosaminidase) and one cytoplasmic non-lysosomal (LDH) enzymes were determined. It has been found that in cells arrested by HU or excess dThR, a progressive cell volume increase with protein/DNA imbalance is correlated with a progressive increase in lysosomal and non-lysosomal hydrolase activities in the cells and in the medium and with a marked lethal effect. Cell volume increase, enhancement of enzyme activities and cell killing could be prevented in HU-arrested cells by concomitant addition of excess dNR (deoxyadenosine, deoxyguanosine, thymidine, deoxycytidine) leading to equal inhibition of DNA and protein synthesis. Control-like values of all parameters were achieved also in cells in which the dThR-inhibiting effect was reversed by dCR addition. It is suggested that a common pathway in the mode of action of the chemotherapeutic agents inducing cell killing through the state of unbalanced growth can be the over-production, abnormal accumulation and progressive leakage of numerous hydrolytic enzymes through the cell membranes, leading in consequence to 'lytic' cell death.

Abstract
The treatment of human erythrocytes with hydroxyurea [HU] results in the azide-dependent changes in osmotic fragility and in increased methemoglobin formation. Similar changes were induced by H2O2 treatment. However when H2O2 in the presence of azide stimulated malondialdehyde production, in the HU-treated cells no malondialdehyde was detectable. When subjected to an oxidant stress [sodium ascorbate] HU-treated erythrocytes were more fragile and revealed changes in the absorption spectrum of the TBA-reactive material in comparison with the cells treated with ascorbate alone. Partial protection by radical scavengers against certain HU-induced changes can be achieved. The results indicate that HU can damage erythrocytes and suggest the radical origin of these effects.

Abstract
In 25 cases cytochemical types of acute leukemia were determined using the classification of Loeffler. Three cytochemical methods used were: p.a.S.-glycogen content, pox-peroxidase activity, and esterase activity determinatione. At the same time selective identification of lysosomes in perypheral blood blast cells was done using vital euchrisine staining and fluorescence microscopy. A correlation was observed between the cytochemical types of acute leukaemia and the lysosomal pattern. The fluorescence method of the identification of lysosomes is suggested for diagnosis of acute leukaemia.
