    BACKGROUND: The aim of this study was to investigate the effects of antioxidant and resuscitation fluids which were used during haemorrhagic shock on tissue ischemia. METHODS: Forty New Zealand type rabbits were divided into four groups as C (control), I (hypertonic saline), H (HAES) and D (Dimethylsulphoxide-DMSO). Haemorrhagic shock was induced by bleeding from carotid artery. Thirty minutes after shock, Group C was not resuscitated while Group I was resuscitated with Hypertonic saline 7.2, Group H with 10 % HAES and Group D with HAES 10 % and DMSO. Thiobarbituric acid reactive substances (TBARS) and lactate levels in blood, liver and small bowel samples were measured. RESULTS: There were no significant differences among the groups tissue and plasma TBARS and lactate levels. CONCLUSION: Resuscitation fluids and addition of antioxidants to the resuscitation fluids do not have any superiorities over each other to prevent tissue ischemic insult in haemorrhagic shock.

    Objectives: To investigate the effects of aprotinin, on blood gasses, oxidant-antioxidant status, and lung histopathology in an experimental bilateral blunt chest trauma model. Methods: Conducted at the Experimental Animal Laboratory of Meram Medical School at Selcuk University, Konya, Turkey, the study comprised 21 New Zealand female albino rabbits who were divided into three groups. Trauma was applied on the sham and aprotinin groups, which was administered intravenous Aprotinin 20.000 U/kg. Arterial blood samples were obtained from all rabbits at hours 0, 3, 24, and 96. At hour 96 after trauma, all rabbits were sacrificed using the decapitation method, and then blood and lung tissue samples were obtained. Blood nitric oxide, malondialdehyde and blood gas measurements were made. Histopathological changes in the lung were examined with a light microscope. Results: While no positive effect of aprotinin was observed on nitric oxide malondialdehyde and partial pressure of carbon dioxide values, it was seen to have an increasing effect on partial oxygen pressure level. Aprotinin had a partial effect on lung histopathology. Conclusion: Aprotinin was determined to have a positive effect on PO2 levels. We could not find any positive effects especially on alveolar haemorrhage.
