چکیده مقاله:
BACKGROUND: Diabetic state potentiates atherosclerosis and the type of edible oil consumed by the individual may affect this further. This study aimed to determine if the common edible oils in Nigeria have any effects on the lipid profiles and arteries of alloxan-induced diabetic male Wistar rats. METHODS: Thirty male Wistar rats were randomly divided into five groups of normal control, diabetic control, animals on diet enriched with refined, bleached deodorized palm oil (RBD-PO), animals on diet enriched with soya oil, and animals on diet enriched with olive oil. At the end of ۸ weeks, the lipid profiles of the animals were determined before sacrificing them. Their aortas were subsequently harvested for histological examination. RESULTS: The olive oil fed group had the highest level of total cholesterol (TC), non-high-density lipoprotein cholesterol (non-HDL-C), lowest HDL-C, and highest artherogenic index (AI). Diabetic animals fed on RBD-PO had a lower non-HDL-C, higher HDL-C, and lower AI than diabetic animals fed on olive oil or soya oil. However, the diabetic animals fed on RBD-PO had the highest triglyceride level. When the aortas were examined histologically, there were no atherosclerotic lesions in all the control and experimental groups except those fed on ۱۰% soya oil enriched diet that had type II atherosclerotic lesions according to American Heart Association (AHA). CONCLUSION: The result of our study showed that RBD-PO appears to offer a better lipid profile in the diabetic animals compared with olive oil and soya oil. Soya oil appears to cause the development of atherosclerosis in diabetic state.
