Problems solved by technology

However, there are two shortcomings in the above methods: first, it takes a long time to complete the replication of the model; second, the uric acid level of the replicated hyperuricemia model is mostly lower than the saturation concentration of uric acid crystals
The above deficiencies will bring more difficulties to the research and treatm

Abstract

The invention discloses a duplication method of rat acute or persistent hyperuricemia model which comprises, (1) selecting male, female healthy rats with the specie of SD and Wistar and 150-450g of body weight, simultaneously administering purines by 100-2000 mg/kg and uric acid depressant by 5-1000mg/kg through stomach filling, hypodermic injection or abdominal cavity injection, (2) after 5-24 hours, administering the rats by the same mode and medicament dose, (3) administering the rats daily continually according to the step (1) and (2), continuing administration for one to two weeks.

Description

1. Technical field [0001] The invention relates to a replication method of an animal model, in particular to a replication method of a rat acute or persistent hyperuricemia model. 2. Background technology [0002] Gout is a group of heterogeneous diseases caused by purine metabolic disorders or (and) decreased uric acid excretion. Clinically, hyperuricemia is the main feature. Hyperuricemia is the biochemical basis of gout, and gout must be accompanied by hyperuricemia. Essentially, there is no strict boundary between hyperuricemia and gout. In recent years, research on the pathogenesis of gout and its drug treatment has become one of the hotspots in the medical field. At present, there is still a lack of mature animal models of gout at home and abroad, and the establishment of animal models of hyperuricemia is a prerequisite for gout research. There are still many imperfections in the existing models, which brings great inconvenience to the research of gout. The followin...
