In vitro study	Uric acid is an endogenous antioxidant that scavenges reactive oxygen species (ROS) including singlet oxygen, oxygen radicals, and peroxynitrite. Incubation with indomethacin significantly increases malondialdehyde (MDA) levels in Caco-2 cells compare to those not treated indomethacin. Incubation with both indomethacin and Uric acid significantly decreases MDA levels compare to those grown in the presence of indomethacin alone. Co-treatment of cells with indomethacin and Uric acid significantly decreases ROS levels compare to those in cells incubated with indomethacin alone. Cell viability in Caco-2 cells treated with both indomethacin and Uric acid is higher than that in cells treated with indomethacin alone. Uric acid has a protective effect on indomethacin-induced intestinal cell changes through its antioxidant activity.
In vivo study	When mice treated with indomethacin are concurrently administered Uric acid orally, ulcer areas are significantly reduced, in a Uric acid dose-dependent manner. Indomethacin increases the ratio of crypt depth to villous height in the ileum, while the ratio is significantly lower when mice are concurrently administered Uric acid orally. Administration of indomethacin also increases the histopathological score of tissue damage in the small intestine, while mice concurrently administered Uric acid orally has a significantly lower histopathological score. The ileal levels of malondialdehyde (MDA) in indomethacin-induced enteropathy model mice orally administered Uric acid are also significantly lower than the levels in mice administered indomethacin alone.

Introduction	uric acid is the end product of purine metabolism, 80% of total uric acid in the body is produced by nuclear protein catabolism, 20% by the intake of food rich in purine catabolism. Uric acid is substantially present in the blood in the free form of the monosodium salt of uric acid and is therefore also referred to as uric acid.
biological activity	Uric acid is an endogenous antioxidant that scavenges reactive oxygen species (ROS), included are singlet oxygen, oxygen radicals, and peroxynitrite.
Use	as an analytical reagent, also used in organic synthesis as a standard solution for the determination of uric acid
production method	1. Dry chicken manure was suspended in 24 times the amount of water, added with an appropriate amount of calcium hydroxide, and allowed to stand. After the precipitation was complete, the supernatant was separated, water was added to the precipitation, the pH was adjusted to 3 with nitric acid, and the mixture was allowed to stand until the precipitation was complete. The supernatant was separated, and the precipitate was resuspended in water to adjust the pH value to 12-12.5 with calcium hydroxide. After filtration, the filtrate was adjusted to PH 3 with nitric acid.
