Abstract
Background
Hyperlipidemia is a risky condition that can lead to atherosclerosis and other cardiovascular problems. Statins are used to treat hyperlipidemia. The most recommended medicine to treat hyperlipidemia is atorvastatin. On the contrary, clinical trials validated statins' negative effects. Omega-3 fatty acids have antioxidant properties and have been shown to improve a variety of disease processes in the general population, including inflammatory and immunological pathways, various cardiovascular diseases, and lipid regulation. The present research aimed to determine how atorvastatin affected the submandibular salivary gland (SMG) and whether omega-3 may have a protective impact.
Methods
Thirty adult male albino rats were divided into three equal groups and received drugs orally as a single daily dose for one week. Control group (I): received normal saline. Atorvastatin group (II): received a dose of 80 mg Kg-1 of Atorvastatin. Group III: received Omega-3 before Atorvastatin. All rats were sacrificed 2 h following the last dose, and blood samples were gathered for the biochemical study of fasting blood glucose level (FBGL). Specimens were obtained and processed for histological and histochemical studies.
Results
Atorvastatin-treated rats showed degeneration of SMG acini. The acinar cells showed cytoplasmic vacuoles with dilated RER. Histochemical results revealed a marked decrease in total proteins. The biochemical study revealed an elevation in FBGL. The administration of Omega-3 with Atorvastatin minimizes these changes.
Conclusion
Atorvastatin has been proven to induce histological changes in SMG, and these changes can be attenuated by Omega-3. However, Omega-3 has no effect on FBGL.
