Composition containing extract of black onion for prevention and treatment of Gout or Hyperuricemia}

The present invention relates to a composition for the prevention and treatment of gout or hyperuricemia comprising the black onion extract as an active ingredient.

Gout is a term used to describe a group of diseases that are found only in humans. Monosodium urate crystals in synovial fluid leukocytes with symptoms of increased serum uric acid, recurrent acute arthritis. ) And the presence of monotidium urate crystals in and around the joints, which often cause malformations and disorders of the joints, and can be manifested in different combinations.

The symptoms of gout in our body are not asymptomatic at first, but gradually progress to degeneration of human tissues, which causes severe subjective symptoms. Frequent, weak stools, frequent symptoms, and the first stage of development, the joints of the limbs at night feel severe pain, wake up symptoms, the second stage of the onset, the pain continues and can not stand up or walk Symptoms appear. In addition, these symptoms may recur after one week and then recur. In addition, as a complication, uric acid stones, diabetes mellitus, obesity, hypertension, arteriosclerosis, and uremia are shown [Kim Yong-seo, Gout ?, Oriental Medicine and Health, 151-154, 2001].

Hyperuricemia is an increase in the concentration of uric acid in the blood. This occurs when the concentration of monosodium urate in serum exceeds the limit of solubility. At 37 ° C., the uric acid saturation of plasma is about 7 mg / dl. Therefore, if this concentration is exceeded, it becomes physicochemically supersaturated. Serum uric acid concentrations are known to be relatively high when they exceed +2 standard deviations from the average serum uric acid concentration of normal subjects. In most epidemiological studies, the upper limit for men is 7 mg / dl and for women 6 mg / dl. For this reason, the substantial upper limit for hyperuricemia is defined as above 7.0 mg / dl. Gout is called "King of Diseases" and "Kings of Kings", a disease that occurs more often with age, and is accompanied by tremendous pain due to inflammatory reactions caused by uric acid crystals in the big toe area, such as allopurinol. Drugs with a myriad of side effects are being used as therapeutics, which requires the development of materials that are safe and free of side effects.

Onium ( Allium cepa L.), which is produced in large quantities in Korea, has long been used as a folk remedy to treat diseases. Onions are effective in preventing and treating cancer, preventing high blood pressure, treating diabetes, treating heart disease, and controlling weight. It has been shown to have excellent effects on the treatment and prevention of geriatric diseases [Kumari, K. and Augusti, KT Anti-diabetec effects of S-methy-lcysteine sulphoxide on alloxan diabetes. Planta Medica., 61, 72]. In addition, the antimicrobial effect of food preservation is known [Zohri, AN, Abedl-Gawad, K. and Saber, S. 1995. Antibacterial, antidermatophytic and antitoxigenic activities of onion ( Allium cep a L.) oil. Microbiol. Res., 150, 167], onion quercetin is known to decrease the activity of carcinogens, inhibit the enzymatic activity of cancer cells, increase the activity of anticancer substances, and inhibit the growth of mutant cancer cells [Jones, E. and Huges, RE 1992.
