    Abstract:
    The aim of the present work is to evaluate the role of a heparin derivative, low molecular weight heparin (LMWH), certoparin on the inflammatory changes in adriamycin (ADR) cytotoxicity on a biochemical basis. Male Wistar rats (140+/-10g) were divided into four groups: untreated control, ADR group (a single dose intravenous injection of 7.5 mg/kg ADR), LMWH control (300 microg/(day rat) s.c. for 1 week) and ADR plus LMWH group (7.5 mg/kg ADR on day 1 of study period followed by LMWH treatment, 300 microg/(day rat) commencing on day 8 and continued for 1 week). At the end of the 2-week experimental period, biochemical assessment of the inflammatory status was carried out in the plasma, cardiac, hepatic and renal tissues. Increased concentrations of plasma C-reactive protein (CRP) and fibrinogen indicated severe inflammation in the ADR cytotoxic rats. These acute-phase inflammatory markers diminished significantly in the LMWH treated group, when compared with the cytotoxic group (p<0.001). Tissue damage was marked by elevated levels of plasma and tissue hexose, hexosamine, hexuronic acid and sialic acid, which were reversed on LMWH administration (p<0.001). The activities of lysosomal enzymes was measured in the experimental groups, and it was observed that the ADR induced rats showed a marked increase in the enzymic activities, while LMWH treated rats revealed normal activities. The present study throws light on the inflammatory changes in the ADR-challenged heart, liver and kidney tissues, and projects the biochemical basis for the anti-inflammatory property of the LMWH, certoparin.
