Purpose: The aim of this study was to investigate the relationship between serum uric acid (SUA) levels and the risk of periodontitis in Korean adults using data from the Korean National Health and Nutrition Examination Survey (KNHANES). Methods: This cross-sectional study used data from the KNHANES 2016-2018 and analysed 12,735 Korean adults aged ≥19 years who underwent oral examinations. Hypouricemia was defined as SUA <3 mg/dL in men and <2 mg/dL in women, and hyperuricemia was defined as SUA ≥7 mg/dL in men and ≥6 mg/dL in women. Results: The weighted prevalence of hypouricemia and hyperuricemia was 0.6% and 12.9%, respectively. The overall weighted periodontitis rate was 30.5%. The frequency of periodontitis in subjects with hypouricemia, normouricemia, and hyperuricemia were 51.1%, 30.3%, and 30.6%, respectively. Study participants with hypouricemia were significantly older, had significantly fasting blood glucose levels, and had better kidney function than non-hypouricemic participants. In univariate logistic regression analyses, hypouricemia was associated with periodontitis, but hyperuricemia was not. The fully adjusted model revealed that the adjusted odds ratio of hypouricemia for periodontitis was 1.62 (95% confidence interval, 1.13-2.33), while the relationship between hyperuricemia and periodontitis in the multivariable logistic regression model was not significant. Conclusions: The results of this study suggest that hypouricemia is associated with an increased risk of periodontitis.

A dose, 1g/kg of ethanol produced experimental hyperuricemia in mouse. Ginseng saponins were tested for their ability to alter the hepatic xanthine oxidase activity and the blood level of uric acid in the ethanol-treated mouse. Intraperitoneal injection of ginseng saponin 4mg/kg markedly decreased the xanthine oxidase activity in the ethanol-treated mouse liver. It was also observed that ginseng saponin reduced the blood concentration of uric acid in experimentally induced hyperuricemia by alcohol treatment. In vitro, it was found that a low concentration of ginseng saponin in the reaction mixture incresed the hepatic xanthine oxidase activity, while a high concentration inhibited both enzyme preparations of normal and ethanol treated mice. In contrast with the xanthine oxidase, uricase activity was not influenced by ginseng saponin as well as in vivo. These results suggest there is a possibility that ginseng saponin may have some therapeutic effect on gout and other hyperuricemia syndrome.

It has been suggested that hyperuricemia is related to the development of essential hypertension. Hypertensive patients with hyperuricemia has decreased glomerular filtration activity as compared to normotensive patients with hyperuricemia. These studies indicates uric acid concentrations in blood is associated with hypertension, Probenecid is an uricosuric agent which decreases uric acid reabsorption at the proximal tubule. Recently, we have shown that probenecid exerts anti-hypertensive action in Spontaneously Hypertensive Rats. Considering these results, I have designed a series of experiments to explore potential mechanism of antihypertensive action, of probenecid. In isolated rat thoracic aorta. probenecid significantly prevented phenylephrine-induced contraction of the blood vessel. When endothelium removed blood vessels were used, probenecid produced same effect as the intact blood vessels, indicating that probenecid directly act through the ${\alpha}$ -adrenergic receptor in vascular smooth muscles rather than through endothelium. These results suggest that one of the mechanism of antihypertensive effects of probenecid is due to the direct inhibition of ${\alpha}$ -adrenergic receptor in blood vessels.

The present study was undertaken to investigate the effect of the water extract of the puffer fish Fugu xanthopterus(FXH) on the alcohol induced hyperuricemia. The normal group and the FXH treated group showed no sigbificant changes in the levels of blood uric acid but, the blood uric acid significantly decreased in the FXh treated rats with 100mg/kg for two weeks compared to the ethanol treated group. There were no significant changes in the activities of uricase, adenosine deaminase, guanine deaminase, and purine uncleoside phosphorylase, among all the test group. But the activitis of liver xanthine oxidase were recovered to the normal level in ethanol +FXH treated group comparing to the ethanol treated group. Furthermore, ethanol+FXH treated rats showed the similar pattern in the levels of blood uric acid and urinary allantoin with normal group. These results indicate that the decreased blood uric acid by the FXH treatment of the alcohol induced hyperuricemia rats may result from decreased activity of hepatic xanthine oxidase.

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.

Objectives : Phyllostachys pubescens and Scutellaria baicalensis are considered to be effective in promoting blood circulation in traditional medicine. In this study, we examined whether a mixture of P. pubescens leaves and S. baicalensis root (BS21) had any anti-obesity, anti-hyperlipidemia, or anti-hyperuricemia effects and the possible mechanisms of action. Methods : We examined the effects of BS21 in high-fat diet (HFD)-induced obese mice. Mice were fed HFD with BS21 (75, 150, or 300 mg/kg) or Garcinia cambogia extracts (245 mg/kg) as a positive control for 8 weeks. At the end of 8 weeks, body weight, liver and adipose weight, adipocyte size, plasma lipid profiles, adipokine and uric acid levels, and adipose tissue expression levels in obesity and uric acid production-related genes were examined. Results : BS21 decreased body weight gain, white adipose tissue, liver weight, adipocyte size, and liver triglyceride accumulation. It also reduced levels of plasma glucose, triglycerides, non-esterified fatty acids, total cholesterol, low-density lipoprotein cholesterol, alanine transaminase, leptin, and uric acid. In contrast, BS21 increased adiponectin levels. Furthermore, BS21 decreased the expression levels of adipogenesis-related genes, such as peroxisome proliferator-activated receptor γ, sterol regulatory element binding protein-1c, and fatty acid synthase, as well as xanthine oxidoreductase, which is involved in uric acid production. Conclusions : These results suggest that BS21 may exert anti-obesity, anti-hyperlipidemia, and anti-hyperuricemia effects in HFD-induced obese mice by regulating the expression of xanthine oxidoreductase and adipogenesis-related genes.

Background: Saengmaeksan (SMS) is a traditional Korean medicine composed of three herbs, Panax ginseng, Schisandra chinensis, and Liriope platyphylla. SMS is used to treat respiratory and cardiovascular disorders. However, whether SMS exerts antihyperuricemic effects is unknown. Methods: Effects of the SMS extract in water (SMS-W) and 30% ethanol (SMS-E) were studied in a rat model of potassium oxonate-induced hyperuricemia. Uric acid concentrations and xanthine oxidase (XO) activities were evaluated in the serum, urine, and hepatic tissue. Using renal histopathology to assess kidney function and uric acid excretion, we investigated serum creatinine and blood urea nitrogen concentrations, as well as protein levels of renal urate transporter 1 (URAT1), glucose transporter 9 (GLUT9), and organic anion transporter 1 (OAT1). The effects of SMS on in vitro XO activity and uric acid uptake were also evaluated. The components of SMS were identified using Ultra Performance Liquid Chromatography (UPLC). Results: SMS-E reduced serum uric acid and creatinine concentrations, and elevated urine uric acid excretion. SMS-E lowered XO activities in both the serum and liver, and downregulated the expression of renal URAT1 and GLUT9 proteins. SMS-E reduced renal inflammation and IL-1b levels in both the serum and kidneys. SMS-E inhibited both in vitro XO activity and urate uptake in URAT1-expressing oocytes. Using UPLC, 25 ginsenosides were identified, all of which were present in higher levels in SMS-E than in SMS-W. Conclusion: SMS-E exhibited antihyperuricemic effects by regulating XO activity and renal urate transporters, providing the first evidence of its applicability in the treatment of hyperuricemia and gout.
