Uric acid crystals

Thus, the presence of uric acid crystals in joints triggers a vicious cycle, resulting in an extremely painful inflammation. A typical localization of acute gouty arthritis is the first metatarsal joint of the foot (podagra). The diagnosis of acute gouty arthritis is confirmed by the detection of urate crystals in the joint or tophus. 

O Gout results from deposition of uric acid crystals in joint spaces, leading to an inflammatory reaction that causes intense pain, erythema, and joint swelling. 

Uric acid crystals were identified on arthrocentesis of the ankle 6 weeks ago. 

If the diagnosis of gout has not been confirmed previously, consider aspiration of an affected joint to identify uric acid crystals. 

In acute uric acid nephropathy, acute renal failure occurs as a result of blockage of urine flow secondary to massive precipitation of uric acid crystals in the collecting ducts and ureters. This syndrome is a well-recognized complication in patients with myeloproliferative or lymphopro-liferative disorders and results from massive malignant cell turnover, particularly after initiation of chemotherapy. Chronic urate nephropathy is caused by the long-term deposition of urate crystals in the renal parenchyma. 

The fact that purine degradation in humans already stops at the uric acid stage can lead to problems, since—in contrast to allantoin—uric acid is poorly soluble in water. When large amounts of uric acid are formed or uric acid processing is disturbed, excessive concentrations of uric acid can develop in the blood hyperuricemia). This can result in the accumulation of uric acid crystals in the body. Deposition of these crystals in the joints can cause very painful attacks of gout. 

It is effective for treatment of acute attacks of gout. It has no effect on renal excretion of uric acid. It binds to tubulin, it interferes with function of mitotic spindles, causes depolymerization and disappearance of fibrillar microtubules in granulocytes. In gout, the useful of colchicine is due to the inhibition of the release of glycoproteins from granulocytes in inflamed joint thus preventing precipitation of uric acid crystals and release of lysosomal enzymes. 

Accumulation of uric acid crystals in the joints, possibly caused by another genetic deficiency, results in gout. 

This disorder is characterized by hyperuricemia with recurrent attacks of acute arthritic joint inflammation, caused by deposition of uric acid crystals. 

Uric acid, the major nitrogenous waste product of uricotelic organisms, is also formed in other organisms from the breakdown of purine bases. Gout is caused by the deposition of excess uric acid crystals in the joints. 

Uric acid is the major nitrogen excretion product in birds and reptiles, where it is responsible for the white, chalky appearance of these droppings. Uric acid is poorly soluble in water, and in humans, formation of uric acid crystals is responsible for the painful symptoms of gout. These crystals are deposited in joints (recall that the classic symptom of gout is an inflamed toe).

The diuretic property of celery has been used to prepare herbal medicine (Houghton, 1995). The ripe seeds, herb and root are diuretic (Lust, 1983 Chiej, 1984 Grieve, 1984). The seeds are used mainly as a diuretic and can help clear toxins from the system, especially in cases of gout where uric acid crystals collect in the joints. Root tinctures have been used to cure urinary disorders, such as urinary stones, and used as a kidney stimulant and cleanser. Fresh juice from the whole plant is also used as a cure for urinary tract inflammations and urethritis (http //www.innvista.com/health/herbs/ celery.htm). The herb is used against kidney complaints (Launert, 1981). 

However laboratory experiments showed that it did not in fact dissolve uric acid crystals, and its use started to decline. Uric acid also dropped out of fashion. However old ideas and practices can take a long time to die out. Lithium continued to be prescribed for gout, arthritis, rheumatism and other complaints. It was listed as a recommended treatment for these conditions until the 1930s in major pharmacopoeias. Even when these publications admitted there was no rational foundations for the use of these (lithium) salts, they still listed indications for lithium use and instructions on how to administer it... 

Uric acid crystals can be deposited in the joints, causing the painful condition known as gout. What, in turn, causes the deposition of the uric acid crystals ... 

Acute gout could cause urate uropathy, whereby uric acid crystals are deposited within the renal tubules, causing intrinsic renal damage. 

Xanthine oxidases occur in the liver and kidneys of humans and animals, and cow s milk is a good source of the enzyme (16, 17, 37). These enzymes catalyze the final step in purine metabolism in primates, the production of uric acid. An excess of uric acid crystallizes in joints producing inflammation (i.e., gout) this condition can be relieved by treatment with allopurinol, an inhibitor of xanthine oxidase.
