Abstract
The present study was carried out to evaluate the effect of Curcuma longa and Thymus vulgaris as antioxidants against the oxidative damage induced by thermally oxidized oil through the evaluation of body performance, hematology, blood chemistry, immunity and associated histopathological lesions in rabbits.
This study was carried out on sixty, 6 weeks old male rabbits divided equally into 6 groups. Gp (1) was kept as normal control. Rabbits in gps. (2, 3 and 4) were given Curcuma longa (13 g / kg ration), Thymus vulgaris (2 g / kg ration) and thermally oxidized oil (5% of ration) respectively for 3 months. Gp.(5) was received Curcuma longa (13 g /kg ration) and thermally oxidized oil (5% of ration) for 3 months. Gp.(6) received Thymus vulgaris (2 g / kg ration) and thermally oxidized oil (5% of ration) for 3 months.
Blood samples and tissue specimens were collected at the end of the 1st, 2nd and 3rd month from starting the experiment. The blood samples were collected from the marginal ear vein and each sample was divided into 3 portions. The 1st portion was 0.5 ml of blood was taken in clean Wasserman tubes containing disodium salts of EDTA for hematological examination. The 2nd portion was 5 ml of blood without anticoagulant was collected in a sterile test tube for separation of serum. The 3rd portion was 2 ml blood collected in a sterile centrifuge tube containing heparin (150 IU/ ml) for phagocytosis. Also specimens from livers, kidneys and spleens were collected from all groups for histopathological examination.
