Oleic acid as a restorative agent in alleviating adrenaline induced altered morphofunctional milieu of gastric tissue and mitochondria

Abstract

The role of oleic acid as a protective antioxidant has recently been recognized. The present study is aimed to explore whether oleic acid can afford protection to rat gastric tissue when challenged with adrenaline. Sixty adult healthy male albino rats were divided into 10 groups comprising of 6 animals each. First group constituted the control. Rats of the second group were injected sub-cutaneously with adrenaline bitartrate at the dose of 0.3mg/kg body weight, every day for a period of 17 days. Rats of the third, to the sixth groups were orally fed with different doses of oleic acid (2.5, 5, 10, 20 mg/kg body weight/day) respectively. The rats of seventh to tenth groups were orally fed with doses of oleic acid as mentioned above and subsequently injected with adrenaline bitartrate at 0.3mg/kg body weight sub-cutaneously. After the treatment period, the animals were euthanized through cervical dislocation following light ether anaesthesia and gastric tissues were collected for morphological and biochemical studies. Subcutaneously administered pharmacological dose of adrenaline bitartrate caused oxidative stress inducing gastric lesion in male albino rats as evident from the altered levels of biomarkers of oxidative stress, activities of antioxidant and mitochondrial enzymes related to energy metabolism with changes in tissue morphology. Pre-treatment of rats with oleic acid dose-dependently protected against these gastric injuries induced by adrenaline indicating the potentiality of oleic acid in protecting against adrenaline induced gastric injury in male albino rats where antioxidant mechanisms appear to play a pivotal role in mediating such protection.

A Comparison of Lipid Contents in Different Types of Peanut Cultivars Using UPLC-Q-TOF-MS-Based Lipidomic Study

“…Consumption of high OA peanuts, which are (proven) highly beneficial antioxidants, may help reduce oxidative stress-induced disorders. Current evidence supports the positive link between OA and health management of gastric injury [5], myocardial injury, cardiovascular insulin resistance, and endothelial dysfunction [6]. However, a comparative analysis on the quality of different peanut cultivars is lacking at present.…”
