The aim was to identify the inhibitory effects of Radix Rosae Laevigatae(RRL) on Monosodium Urate(MSU)-induced gout in rats. After pretreatment of RRL I (125mg/kg), RRL II (50mg/kg) for seven days followed by injection of MSU solution, the various indicators related to gout were measured, such as hematological and serum levels and including joint inflammation. Also, it was investigated whether RRL directly inhibits the activity of xanthine oxidase in vitro. As a result of this study, RRL didn't show the cytotoxicity on cell proliferation, but it showed significant inhibition of activity of xanthine oxidase in vitro. RRL slightly inhibited joint inflammation induced by MSU though not with statistical significance. RRL partially decreased MSU-induced BUN, creatinine, WBC, ESR elevation and significantly decreased MSU-induced AST, ALT, uric acid in serum. These results suggest that RRL has therapeutic effects that are applicable to prevention and treatment of gout, and should be further investigated.

Objective : To identify the inhibitory effects of Commiphora Myrrha (CM) on monosodium urate (MSU)-induced gout model in rats. Materials and Methods: After pretreatment with CM-I (125mg/kg) or CM-II (50mg/kg) for 7 days followed by ones injection of MSU solution. the various indicators related to gout were measured on hematological and serum level including joint inflammation, Also, it was studied whether FBM directly inhibits the activity of xanthine oxidase in vitro. Results : As a result of this study, CM didn't show cytotoxicity in Jurkat cells, but it showed significant inhibition of activity of xanthine oxidase in vitro. CM slightly inhibited joint inflammation induced by MSU though not with statistical significance. CM partially decreased MSU-induced albumin, globulin, AST, ALT, BUN, creatinine. WBC, platelet count and ESR level and significantly decreased MSU-induced uric acid in serum. Conclusion : These results suggest that CM has therapeutic effects that are applicable to prevention and treatment of gout, and should be further investigated.

Familial juvenile hyperuricemic nephropathy is an autosomal dominant disease characterized by progressive renal disease and hyperuricemia or gout, affecting young people of either sex equally. There are two biochemical markers of this disorder. The first is hyperuricemia disproportionate to the degree of renal dysfunction; the second is a grossly reduced clearance of uric acid relative to creatinine, dispropotionate to age, sex and degree of renal failure. We experienced 2 family members with hyperuricemia. One family member, a 13-year-old girl who had suffered from tophaceous gout and chronic renal failure. Her younger brother also had hyperuricemia and moderately reduced renal function. Their urinary excretion fractions of uric acid($FE_{uric\;acid}$) were reduced and renal biopsy specimens showed interstitial fibrosis with tubular atrophy and interstitial urate crystal deposition. We have treated these two patients with allopurinol but we have done renal transplantation because she progressed to end stage renal disease at 16 year old age.

In order to obtain practical application of Yiyiren-tang against gout disease, water extract of modified Gami-Yiyiren-tang(GYYT) added with Lonicera japonica is prepared through decoction and freeze drying. The effects were evaluated with blood sample from ICR mice treated with MSU intra-peritoneal injection 1 time a day, 3 days consecutively. The results were as follows. GYYT decreased C-reactive protein level and HDL cholesterol levels. But the creatinine, the LDL cholesterol levels, triglyceride and uric acid levels were not changed were decreased significantly. These results show that GYYT can be used effectively against the urate-related gout disease. But not better than effects of the Gami-daehwangmokdan-tang.

In order to obtain practical application of Daehwangmokdan-tang gout disease, water extract of Gami-daehwangmokdan-tang(GDMT) added with Lonicera japonica is prepared through decoction and freeze drying. The effects were evaluated with blood sample from ICR mice treated with MSU intra-peritoneal injection 1 time a day, 3 days consecutively. The results were as follows. GDMT decreased BUN, creatinine and C-reactive protein level in serum significantly. But the HDL and LDL cholesterol levels were not changed in spite of positive tendency in HDL cholesterol. Triglyceride and uric acid levels were decreased significantly too. These results show that GDMT can be used effectively against the urate-related gout disease.

Extra-articular deposition of monosodium urate crystals is a widely recognized manifestation of gout. However, gouty infiltration of flexor tendons in the hand resulting in tendon rupture is exceedingly rare. This case report highlights a patient with gouty infiltration of flexor tendons in the right middle finger resulting in rupture of both the flexor digitorum profundus and flexor digitorum superficialis. Given the extent of gouty infiltration and need for pulley reconstruction, the patient was treated with two-stage flexor tendon reconstruction. Febuxostat was prescribed preoperatively to limit further deposition of monosodium urate crystals and continued postoperatively to maximize the potential for long-lasting results. Prednisone was prescribed between the first- and second-stage operations to prevent a gout flare while the silicone rod was in place. In summary, tendon rupture secondary to gouty infiltration is the most likely diagnosis in patients with a history of gout presenting with tendon insufficiency.

The influence of Panax ginseng on alcohol-induced hyperuricemia were observed. Changes of uric acid blood levels and hepatic xanthine oxidase activities were studied by means of treating alcohol intoxication with ginseng. It was found that a single dose (4 mg/Kg) of ginseng saponin administered intraperitoneally significantly inhibits the hepatic xanthine oxidase activities and decrease urate blood levels in ethanol-induced hyperuricemic mice. It was also observed that there were some difference in pharmacological aspect between Panax ginseng and allopurinol which is a potent inhibitor of xanthine oxidase from any sources.

Ethanol extract of Actinidia polygama Max. (AP) was examined for hypouricemic activity in potassium oxonateinduced hyperuricemic animal model. Ethanol extract of AP lowered the plasma uric acid level by 20％ when compared to the hyperuricemic control group. AP ether fraction at a dose of 100 mg/kg showed 27％ reduction, whose efficacy was comparable to the probenecid-treated group. AP ether fraction-treated group also showed 23％ reduction of urate in urine and this result suggests that AP ether fraction has anti-gout activity probably due to xanthine oxidase inhibition.

Idiopathic renal hypouricemia is a disorder characterized by impaired urate handling in the renal tubules. Most patients with hypouricemia are asymptomatic and are found incidentally, but the condition is known to be at high risk for exercise-induced acute renal failure or urolithiasis. URAT1 protein encoded by SLC22A12 gene has been identified recently as a urate/anion exchanger in the human kidney. Inactivation mutations in SLC22A12 gene have been shown to cause renal idiopathic hypouricemia. We experienced a 3-year-old boy who presented with persistent orange-colored urine since infancy. His urine contained many uric acid crystals, while the serum showed hypouricemia(0.7 mg/dL). The fractional excretion of uric acid was increased to 41.7%. SLC22a12 gene analysis revealed W258X homozygote alleles. Renal hypouricemia must be included in the differential diagnosis of red-urine and SLC22A12 gene analysis is recommended in idiopathic renal hypouricemia.

Pyrazinamide, an amide of pyrazinoic acid, is widely used in combination with other drugs for the treatment of tuberculosis. It was attempted to observe the effect of pyridoxal on the pyrazinamide induce hyperuricemia in this study. It was observed that the values of serum transminases were not changed in mice injected pyrazinamide and pyrazinoic acid, respectively (100, 200, and 300mg/kg) compared with control. Blood urate levels were increased in mice treated with these drugs in a dose dependent manner. After pyrazinoic acid was administered intraperitoneally at a dose of 300mg/kg pretreated with 50mg/kg of pyridoxal once daily for 4 days, the blood levels of uric acid and pyrazinoic acid were decreased significantly.
