BACKGROUND: Statins are among the first line of pharmacological treatment of lipid disorders and lowering serum cholesterol, but they have many side effects.
AIM: The study aim was to evaluate the role of raisins in protecting the thyroid function and structure in a rat model of hypercholesterolemia, through biochemical and histopathological investigation.
MATERIALS AND METHODS: Thirty male rats were randomly divided into three groups (n = 10 each) of albino rats included the control, high cholesterol diet (HCD)-fed for 13 weeks and HCD plus Raisins were included in this study. Blood levels of glucose, insulin, cholesterol, lipids, thyroid-stimulating hormone (TSH), T3, T4, oxidants/anti-oxidants were assessed. Thyroid gland was processed and examined histopathologically using light and electron microscopy.
RESULTS: Feeding HCD resulted in hypercholesterolemia in rats after 13 weeks as evidence by lipid profile. Ingestion of raisins along with HCD resulted in a significant (P < 0.001) decrease in the levels of insulin, blood glucose, thyroxine (T4) and malondialdehyde (MDA), while the levels of TSH, T3 and total anti-oxidant capacity significantly (P < 0.001) elevated. Raisins histologically alleviated the HCD-induced structural changes in the thyroid glands that included degenerated mitochondria and increased lipid droplets in the cytoplasm.
CONCLUSIONS: Simultaneous administration of raisins along with HCD, administrated for a short time, could modulate the negative effect on thyroid gland structure and function.
