Background: Multiple myeloma (MM) is a haematological cancer characterized by clonal proliferation of plasma cells.The aim of this study was to investigate the activity of serum paraoxonase-1 (PON1) and arylesterase (ARE) in multiple myeloma with and without free light chain excretion(FLCe-MM and NFLCe-MM); as well as to investigate possible alterations in oxidative stress parameters. Materials and Methods: Total thiol (T.thl), oxidative stress index (OSI), total oxidant status (TOS) and total antioxidant status (TAS) were examined in addition to the PON1 and ARE enzyme activities in twenty one FLCe-MM and nineteen NFLCe-MM subjects. Routine parameters like lipid panel, serum total protein, albumin, creatinine, blood urea nitrogen (BUN), uric acid and hemoglobin levels were compared with the oxidative stress markers. Results: Serum total protein, BUN, creatinin, and uric acid levels were significantly higher (p=0.04, p=0.001, p=0.001 and p=0.0022, respectively), while hemoglobin and albumin levels were significantly lower in FLCe-MM patients (p=0.009 and p=0.04,respectively). PON1 and ARE activities were significantly lower in patients with FLCe-MM compared to those with NFLCe-MM (p=0.001 and p=0.008, respectively). Conclusions: Depending on our results of prognostic markers of MM such as age, hemoglobin, albumin, and creatinine we feel confident to presume FLCe-MM as a subgroup with a worse prognosis. A decrease in PON1 and ARE activities may contribute to the prognosis and may be used as a prognostic tool in MM.

Obesity is correlated with diabetes mellitus, hyperlipidemia, hypertension, cardiovascular, renal, neurologic, psychological and many other disease. Owing to the elevated income and behavioral changes, the prevalence of obesity has remarkably increased in Korea also. Considering the trend of the epidemic, we can easily expect the excessive spendings for the treatment of the obesity-related diseases in near future. In order to check the prevalence of obesity and serum lipid levels of Korean employees, we analyzed the medical check-up sample data of 10,332 adults who took physical check-ups at an institute in 2006. Through the logistic regression analysis we found the prevalence rate of total risk group showing ${\geq}23.0Kg/m^2$ was 57.4% and uric acid was found to be a definitive factor in the prevalence of obesity. Among the adults who eat more meat, drink more and smoke more smoking, the values of BMI, uric acid, cholesterol, HDL- and LDL-cholesterol and TG were significantly higher than rest of the examinees. And the average BMIs were significantly higher among those who have risk factors of liver disease, hypertension, cardiovascular and heart disease, and diabetes mellitus.

The application of polyphenols has attracted great interest in the field of functional foods and nutraceuticals due to their potential health benefits in humans. However, the effectiveness of polyphenols depends on their bioactivity and bioavailability. In the present study, the bioactive component from green tea extract (GTE) was administrated orally (50 mg/kg body weight/day) as free or in a microencapsulated form with maltodextrin in rats fed a high fructose diet. High fructose diet induced features of metabolic syndrome including hypertriglyceridemia, hyperuricemia, increased serum total cholesterol, and retroperitoneal obesity. In addition, myocardial fibrosis was increased. In rats receiving high fructose diet, the lowering of blood triglycerides, total cholesterol, non esterified fatty acid (NEFA) and uric acid, as well as the reduction in final body weight and retroperitoneal fat weight associated with the administration of GTE, led to a reversal of the features of metabolic syndrome (P < 0.05). In particular, the administration of microencapsulated GTE decreased myocardial fibrosis and increased liver catalase activity consistent with a further alleviation of serum NEFA, and hyperuricemia compared to administration of GTE. Taken together, our results suggest that microencapsulation of the bioactive components of GTE might have a protective effect on cardiovasucular system by attenuating the adverse features of myocardial fibrosis, decreasing uric acid levels and increasing hepatic catalase activity effectively by protecting their bioactivities.

Objectives: Several studies have investigated the effects of serum uric acid (SUA) levels on chronic kidney disease (CKD), with discrepant results. The effect of SUA levels on CKD development was studied in the Korean rural population. Methods: A total of 9695 participants aged ${\geq}40years$ were recruited from 3 rural communities in Korea between 2005 and 2009. Of those participants, 5577 who participated in the follow-up and did not have cerebrovascular disease, myocardial infarction, cancer, or CKD at baseline were studied. The participants, of whom 2133 were men and 3444 were women, were grouped into 5 categories according to their quintile of SUA levels. An estimated glomerular filtration rate of < $60mL/min/1.73m^2$ at the time of follow-up was considered to indicate newly developed CKD. The effects of SUA levels on CKD development after adjusting for potential confounders were assessed using Cox proportional hazard models. Results: Among the 5577 participants, 9.4 and 11.0% of men and women developed CKD. The hazard ratio (HR) of CKD was higher in the highest quintile of SUA levels than in the third quintile in men (adjusted HR, 1.60; 95% confidence interval [CI], 1.02 to 2.51) and women (adjusted HR, 1.56; 95% CI, 1.14 to 2.15). Furthermore, CKD development was also more common in the lowest quintile of SUA levels than in the third quintile in men (adjusted HR, 1.83; 95% CI, 1.15 to 2.90). The effect of SUA was consistent in younger, obese, and hypertensive men. Conclusions: Both high and low SUA levels were risk factors for CKD development in rural Korean men, while only high levels were a risk factor in their women counterparts.

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.

Objectives: This experiment was conducted to verify the effects of Chungganhaeju-tang(Qingganjiejiu-tang) on the alcohol metabolism and liver functions, by measuring the activity levels of ADH and ALDH, as well as glucose, triglyceride, and BUN. Damage of the liver cells caused by alcohol was determined through the examination of serum levels of AST, ALT, ALP, LDH, and uric acid. Methods: Sprague-Dawley rats were used in this experiment and the rats were divided into control and experiment groups. Chungganhaeju-tang(Qingganjiejiu-tang) extract was orally administered in the experiment group for three weeks. Each group was further classified into two sub-groups, and control group's blood was taken without oral ingestion of alcohol, while the experiment group' s blood was withdrawn after ingestion of alcohol. Evaluation of damage level was done considering the presence of extract and alcohol. Results: In this experiment, Chungganhaeju-tang(Qingganjiejiu-tang) significantly suppressed the activity of ADH which is a precursor enzyme of acetaldehyde, but didn't cause significant changes in the activity of ALDH which is a catabolic enzyme. Decreased glucose level due to alcohol consumption was recovered back to the normal level and increased levels of triglyceride, BUN, AST, ALT, ALP, LDH, and uric acid were significantly reduced. Conclusions: These experiment results suggest that Chungganhaeju-tang(Qingganjiejiu-tang) inhibits the formation of acetaldehyde in the metabolism of alcohol, and affects the recovery of weakened liver functions due to alcohol.

The objective of this study was to analyze the relationship between blood pressure and serum mineral concentration in hypertension patients subjected to dehydration. The data were collected and analyzed for 7,109 patients who visited a hospital for their health checkup from 2011 till 2015. Respondents were classified into four groups depending upon their state of hypertension and dehydration: control group (no hypertension and no dehydrated), dehydrated group, hypertension group, and dehydrated with hypertension group. Hypertension group was found to have higher levels of serum sodium, calcium, and uric acid than the normal group, whereas the dehydrated group was found to have higher levels of serum sodium and potassium than the normal group. In effect, no significant correlation was directly observed between the hypertension group and dehydration group. However, there were significant negative correlations between dehydration of the old-aged group and their serum mineral concentrations, which are reportedly related to hypertension. Thus, dehydration prevention measures in the elderly over 65 could mitigate hypertension problems.
