Effects of autohemotherapy on hematological responses in Wistar female rats Autohemotherapy in rats

Introduction: Autohemotherapy is a type of treatment that have acquired an opposite role and have presented its efficiency strived by the medical community for many reasons. In this study we aimed to evaluate the effects of authohaemotherapy on hematological response. Method: We used Wistar female rats (300g). The study consisted in a control group and a treatment group, blood samples were collected at the first day and at the eighth day after the application. In the both groups we collected 300 μl of blood from each rat through a syringe with a previously prepared solution of 30 μl of sodium citrate 3.2%. In the autohemotherapy group the blood sample was immediately injected in the quadriceps muscle on the back of the thigh hind limb. Rats from the control group did not receive intramuscular blood application. The cellular count was done through flow cytometry and the samples were dosed for immunoglobulin. Results: In the both groups we observed increased production of erytrocites, hemoglobin and platelet (p<0.05). However, there was reduction of basophil in the control group and reduction of lymphocyte, monocyte and neutrophil in the both groups. No effects were observed in IgA, IgG and IgM levels. Conclusion: Autohemotherapy did not influence hematological responses in Wistar female rats.

Atividade imunomoduladora de parasporina de Bacillus thuringiensis sobre linfócitos e monócitos humanos

Bacillus thuringiensis is an environmental bacteria that produces a group of crystallizable proteins (Cry) that are toxic for several insects and worms species. Recently, it was described a novel class of Cry proteins called parasporins (PS) that showed cytotoxic effects on animal and human tumor cells. Six types of PS have been described so far, PS1 to PS6, and their cytotoxic activity has been studied. However, the direct effect on tumor cells has been the current research focus, while the immunomodulatory role of the PS has not been studied yet. Therefore, this study aimed to verify whether PS of TC 2.3.1R6 B. thuringiensis strain has immunostimulatory activity on human lymphocytes and monocytes. We have evaluated the protein toxicity against human cells, the lymphoproliferative activity and the effects on peripheral blood monocytes. The PS-PK showed no toxic or stimulating activity on lymphocyte proliferation. However, it inhibited the spontaneous production of IL-10 as well as ConA-induced and the production of IFN-γ. PS-PK decreased the release of hydrogen peroxide and increased the production of TNF- α by monocytes. PS-PK performed inhibitory production of hydrogen peroxide and TNF-α by monocytes, whereas PS-Tp showed stimulation of the production of hydrogen and TNF-α

Sister chromatid exchanges and chromosome aberrations in lymphocytes of nurses handling antineoplastic drugs

Chromosomal aberrations (CA) and sister-chromatid exchanges (SCE) were investigated in peripheral lymphocytes of 15 nurses and nurse's aides handling cytostatic agents in hospital oncology units. Significantly increased frequencies were noted for both CA and SCE rates when the exposed individuals were compared with 15 nurses working in other hospital units and to a control sample matched by sex and age. This points to the need for emphasizing protective measures in the handling of anti-neoplastic agents.
