We investigated the anti-obesity effects of Ishige okamurae extract (IOE) on body weight, epididymal adipose tissue weight, plasma lipid levels, and leptin levels in high-fat diet (HFD)-induced obese mice. After inducing obesity by feeding 45% HFD for 4 weeks, C57BL/6J mice were randomly assigned to HFD or HFD containing 5% IOE, and then fed for 6 weeks. The body weight and epididymal adipose tissue weight were increased by HFD, but they were significantly less in animals fed HFD containing 5% IOE than in those fed HFD. Levels of plasma triglyceride, total cholesterol, and LDL-cholesterol were significantly lower, but the HDL-cholesterol level was significantly higher in animals fed HFD containing 5% IOE compared with the HFD group. The plasma leptin level was significantly lower in animals fed HFD containing 5% IOE. The diet containing 5% IOE did not show any adverse effects on liver and kidney functions. These results suggest that IOE has a potential as anti-obesity agent by reducing body weight and lowering the levels of obesity-related factors in plasma.

In postmenopausal women, estrogen deficiency can be associated with metabolic diseases, such as obesity, diabetes, and cardiovascular diseases. The purpose of this study was to investigate factors related to lipid, glucose and antioxidnat metabolism. Sprague-Dawley female rats were subjected to either bilateral ovariectomy or sham operation and randomly divided into 3 dietary groups, (n=8) sham-operated fed with normal diet (SHAM), ovariectomized fed with normal diet (OVX), and ovariectomized fed with normal diet supplemented with Eucommia ulmoides extract (OVX-EU). The OVX-EU group showed significantly lower body weight, triacylglycerol, and total cholesterol than that showed by the OVX group. In addition, the OVX-EU group showed improved lipogenesis, glucose-regulating enzyme activities, adipokine and antioxidant enzyme activities. These findings demonstrate that extracts from E. ulmoides extract can be used as a functional food.

The effects of dietary eggs on liver and serum lipids, serum protein and mineral concentrations, and enzyme activities in male rats were studied. Sprague-Dawley rats were fed four types of diets for 4 weeks, respectively: a control diet, a control diet supplemented with 5, 10 or 15% eggs powder. In rats fed 5, 10 or 15% egg diets the body weight gain, the food intake, the weights of kidney and epididymal fat pad were similar to those in rats fed the control diet. The hepatic weight, hepatic cholesterol and triglyceride concentrations of rats fed the all egg diets were significantly higher than those of rats fed the control diet. The concentrations of total cholesterol, HDL-cholesterol, LDL+VLDL-cholesterol, triglyceride and phospholipid in the serum of rats fed the all egg diets were similar to those of rats fed the control diet. In the rats fed 5% egg diet the HDL-cholesterol/total-cholesterol ratios was significantly increased, and the atherogenic index was significantly decreased compared with those in the rats fed 10 or 15% egg diets. The serum total protein and albumin concentrations of rats fed 10 or 15% egg diets were significantly increased compared with those of rats fed the control diet. The serum calcium levels of rats fed the all egg diets were significantly increased compared with those of rats fed the control diet. No differences were noted in the concentrations of urea nitrogen, creatinine, glucose and hemoglobin, and activities of GOT, GPT, ${\gamma}-GTP$ and alkaline phosphatase in the serum among the rats with on all the experimental diets. These results showed that the all egg diets feeding increased cholesterol and triglyceride concentrations in liver, but no differences lipids and lipoprotein cholesterol concentrations in serum of rats.

Three different diet were made with meat for Crossbred pig ($^{\circ}_{+}$, 195 days old, $l15{\pm}5\;kg,\;Landrace{\times}Yorkshire{\times}Duroc$) and used as feed for rats after transformed into 12% protein, These diets include a pork not fed with tangerine peel during finishing period (Control, $T_0$), a pork fed with 3 and 5% tangerine peel during growing and finishing period, respectively ($T_1$), and a pork fed with 6 and 10% tangerine peel during growing and finishing period respectively($T_2$). The effects of the diet on physiological activities of rats were studied by feeding 17 weeks-old Sprague-Dawley rats with the three diets for 4 weeks. The feed intake, weight gain, feed efficiency ratio, and weight of liver, kidney, spleen and epididymal fat pad for the rats was similar among the diets. The total lipid level of liver was similar among $T_0,\;T_1\;and\;T_2$. However, it was found that $T_1\;and\;T_2$ had significantly lower triglyceride and cholesterol level than $T_0$(p<0.05). All the diet groups showed similar trends in terms of the serum total lipid, phospholipid, triglyceride, total cholesterol, HDL-cholesterol and LDL-cholesterol level, and atherogenic index, hemoglobin level, and ${\gamma}-GTP$, ALT, AST and ALP activities.

Purpose: Clinical and laboratory features of two Kawasaki disease (KD) groups were evaluated; the patient with pyuria and those without pyuria. Methods: From January 2015 to December 2016, the medical records of 140 (86 males and 54 females) inpatients with KD were retro-spectively analyzed. Results: Forty-eight KD patients (34.3%) presented with pyuria. KD patients with pyuria showed a higher level of C-reactive protein (CRP) and a higher proportion of elevated liver enzymes than those without pyuria. There were no differences in the proportions of unresponsiveness to intravenous immunoglobulin and coronary artery lesions between the two groups. Six KD patients (12.5%) with pyuria underwent a renal imaging study to rule out the possibility of a urinary tract infections. Thirty-two KD patients (66.7%) with pyuria received treatment with antibiotics in addition to the standard treatment for KD. Conclusions: KD patients with pyuria showed a higher level of CRP and elevated levels of liver enzymes than those without pyuria. These findings suggest that KD patients with pyuria have more severe systemic inflammation than those without pyuria.

Diets consist of two different pork samples: pork of a Jeju native pig ( 260 days old, $101{\sim}103kg$ ) not fed tangerine byproduct during finishing period ($T_0$), and pork fed 8% and 15% tangerine byproduct during growing and finishing period ($T_1$), respectively. The effects of the diet on the physiological activities of rats were studied by feeding 17-week old rats with the two diets for 4 weeks. There was no significant difference between $T_0$ and $T_1$ in the rat's feed intake, feed efficiency ratio, and weight gain. Furthermore, there was no significant difference between $T_0$ and $T_1$ in the rat's weight of liver, kidney, spleen, epididymal fat pad, triglyceride and cholesterol of liver. Both $T_0$ and $T_1$ showed similar trends in terms of total lipid, phospholipid, triglyceride, total cholesterol, atherogenic index, protein, glucose, hemoglobin level, mineral level, and ${\gamma}$-GTP, ALT, AST and ALP activities. However, $T_1$ showed the trend of increasing amount of the serum's HDL and LDL cholesterol level, compared with $T_0$.

Rubus coreanus has been used as a traditional medicine in Asia because of its various pharmacological properties. This study examined the effects of protocatechuic acid (PCA), one of phenolic compounds derived from R. coreanus on the lipid metabolism in high cholesterol diet-induced mice. A total of 30 male C57BL/6 mice were divided into 5 groups with 6 mice in each group as follows: (1) Control mice received normal diet (ND). (2) Mice received high-cholesterol diet (HCD) plus water, 10% sucrose solution and treated daily oral phosphate-buffered-saline (PBS) of equal volumes through gavage. (3) Mice received HCD and treated daily with 25 mg/kg b.w./day of PCA (4) with 50 mg/kg b.w./day or (5) with 10 mg/kg b.w./day of simvastatin via oral gavage for 12 weeks. Body weights were measured weekly for a period of experiment. After treatment, liver, thymus, spleen and kidney were harvested and weighed, and the lipid metabolite profiles (total cholesterol, triglyceride (TG), HDL-cholesterol (HDL-c), LDL-cholesterol (LDL-c) and liver-damaging markers (GOT and GPT) in serum were examined. PCA significantly reduced the total cholesterol, TG, LDL-c level and increased the HDL-c level. PCA administration also significantly reduced the levels of GOT and GPT. These results indicate that the PCA could be used as a functional material for lowering lipid and an adjuvant for the treatment of hyperlipemia.

The purpose of this study was to identify the effect on plasma levels of lipid and lipid peroxidation by administration of lactic acid bacteria (Lactobacillus bulgaricus, Streptococcus thermophilus, Lactobacillus acidophilus) fermented Orostachys malacophyllus (FOM) in alcohol fed rats. Male Sprague-dawley rats were randomly divided into seven groups: normal diet group (N), alcohol treated group (C), 2.5% (w/w) or 5% (w/w) OM treated group (2.5OM, 5OM), 2.5% (w/w) or 5% (w/w) fermented OM treated group (2.5FOM, 5FOM) and silymarin treated group (SM) as a positive control. As a result of measuring serum total lipid, C group were increased total lipid, free fatty acid content and were decreased HDL-cholesterol content, but 5FOM group were significantly decreased lipid content and were increased HDL-cholesterol content and accordingly reduced the incidence of atherosclerosis. Serum total protein content was similarly measured in all groups and serum albumin content was decreased in alcohol feeding groups compared to the N group. The 5FOM group had significantly decreased liver and serum triglycerides compared to the C group. The TBARS content in the liver, serum, testis, kidney, spleen, and heart were slightly decreased in the 5FOM group compared to the C group and the 5FOM group had an increased glutathione concentration. The 5FOM treatment was showed analogous results to those of the SM treatment, suggesting that FOM is can improve the lipid profiles of alcohol-fed rats.

This study was performed to evaluate the anti-obesity and lipid-lowering effects of phytoplant diets in rats fed with a high-fat/cholesterol diet (HFCD). Experimental diet formulae contained various phytoplants such as brown rice, barley, soybean, germinated brown rice, malt, black bean, sea tangle, and/or dietary fibers including polydextrose, garcinia combogia, glucomannan, ${\small}L$-carnitine, and chitosan. Male Sprague-Dawley rats were fed with a HFCD for 6 weeks and then fed with a HFCD with/without phytoplants for another 6 weeks. Rats fed with phytoplant diets showed lower body weights, liver weights, visceral fat levels, and blood lipid levels compared to those of rats fed with HFCD alone. In addition, rats administered phytoplant diets showed increased daily feces production during the second experimental phase. These results suggest that phytoplant diets improve body weight, feces production, adipose tissue weight, and lipid metabolism.
