INFLUENCE OF CURCUMIN ON CYTOKINES CONTENT AND ANGIOTENSIN-CONVERTING ACTIVITY UNDER INTRAHIPPOCAMPUS ADMINISTRATION OF β-AMYLOID PEPTIDE IN RATS

The purpose of this study was to investigate the effect of curcumin on cytokine response and angiotensin-converting activity in terms of intrahippocampus administration of ß-amyloid peptide in rats. Animals with experimental model of Alzheimer's disease received nasal therapy aqueous solution of curcumin. Recorded concentration of cytokines (interleukin-1ß, interleukin-6, interleukin-10, tumor necrosis factor-α) and angiotensin-converting activity in the parts of the brain (cerebral cortex and hippocampus) and blood serum, as well as indicators of conditional reflex escapers action. Install a reduction in cytokine response intrahippocampus administering Aß42_Human and angiotensin-converting activity inhibition in the brain but not in the blood serum of animals under the action of curcumin. Recorded improvement in cognitive performance in rats with a model of Alzheimer's disease as a result of curcumin therapy. Nasal treatment with an aqueous solution of curcumin has anti-inflammatory effect in the targeted parts of the brain (сerebral cortex and hippocampus), but inhibits angiotensin-converting activity.
