The Effect of Arachidonic acid and calcium deposition on Bony mass in experimental animal

Bones are one of the most important parts of the human body ,as weak bones may lest to general weakness as it shields for all body system . Arachidonic acid is a polyunsaturated fatty acid present in the phospholipids(especially phosphatidylethanolamine, phosphatidylch oline, and phosphatidylinositides) of membranes of the body's cells, and is abundant in the brain, muscles, and liver. Skeletal muscle is an especially active site of arachidonic acid retention, accounting for roughly 10-20% of the phospholipid fatty acid content on average. It still plays fundament al role in reducing pathogenicity. This study aim to Investigated the effect of Arachidonic acid(deficiency & treatment) on calcium deposition and bones density. Compare the results of those groups with the group affected by decrease Arachidonic acid and increase calcium deposition . Experimental design: Thirty sex healthy adult male albino rats were fed on standard diet for one week for adaptation. After this week, they were divided into six groups, The first group (6 rats) fed on basal diet (as a negative control group). The second group (6 rats) fed on standard diet without aracidonic acid and double dose of calcium (as a positive control group). The third group (6rats) fed on standard diet with aracidonic acid( 1000 mg) and the double dose of calcium The fourth group (6 rats) fed on standard diet with aracidonic ac id(1150mg ) and the double dose of calcium Journal of Home Economics, Volume 30, Number (1), 2020 160 The five group (6 rats) fed on standard diet with aracidonic acid (1300 mg) and the double dose of calcium The last group (6 rats) fed on standard diet with aracidonic acid (1450 mg) and the double dose of calcium Conclusion: Results obtained for this study led to several conclusions: it is important for The Relation ship between Arachidonic acid and first time walking in children bone mass increase and the best Results in 1450 mg.
