Objectives : Sansachunghyul-tang (山楂淸血湯) is a new formula consist of some herbs to treatment of hyperlipidemia. The lipid-lowering effects of the water extract of Sansachunghyul-tang (SCT) were examined using Triton WR1339-induced hyperlipidemic rats. Methods : Hyperlipidemia was induced by intravenous injection of Triton WR1339 (tyloxapol) at 200 mg/kg body weight. Four groups of experimental animals were used: normal, control, and two sample groups. Sample groups were injected with SCT (100 and 1000 mg/kg) for 7 days. Results : SCT produced statistically significant lowering effects on levels of total cholesterol (81.8 and 83.1%, p < 0.01, respectively), triglyceride (88.9 and 93.4%, p < 0.01, respectively), and phospholipid (86.7 and 94.3%, p < 0.01, respectively) than the control group. Taken together, SCT improved parameters of the HDL-cholesterol and LDL-cholesterol levels. Conclusions : In conclusion, These results suggest that SCT could act as a potent antihyperlipidemic in therapeutics for hyperlipidemia.

We have previously observed that feeding with single-cell hemoprotein (heme-SCP) in dogs (1 g/day for 6 days) and broiler chickens (1 ppm for 32 days) increased the proportion of lactic acid bacteria in the gut while reducing their body weights by approximately 1~2%. To define the roles of heme-SCP in modulating body weight and gut microbiota, obese C57BL/6N mice were administered varied heme-SCP concentrations (0, 0.05, and 0.5% heme-SCP in high fat diet) for 28 days. The heme-SCP diet seemed to restrain weight gain till day 14, but the mice gained weight again later, showing no significant differences in weight. However, the heme-SCP-fed mice had stiffer and oilier bodies compared with those of the control mice, which had flabby bodies and dull coats. When mice were dissected at day 10, the obese mice fed with heme-SCP exhibited a reduction in subcutaneous fat with an increase in muscle mass. The effect of heme-SCP on the obesity-associated dyslipidemia tended to be corroborated by the blood parameters (triglyceride, total cholesterol, and C-reactive protein) at day 10, though the correlation was not clear at day 28. Notably, the heme-SCP diet altered gut microbiota, leading to the proliferation of known anti-obesity biomarkers such as Akkermansia, Alistipes, Oscillibacter, Ruminococcus, Roseburia, and Faecalibacterium. This study suggests the potential of heme-SCP as an anti-obesity supplement, which modulates serum biochemistry and gut microbiota in high-fat diet-induced obese mice.

Purpose: Childhood obesity is an increasing public health issue worldwide. We examined dietary patterns among adolescents in a dormitory school, identified obese adolescents and tried to intervene to improve food habits and physical activity. Methods: We conducted an experimental prospective longitudinal study based on 36 obese (body mass index $[BMI]{\geq}95th$ percentile) adolescents (aged 12-18 years) compared with controls (healthy children: normal age-appropriate BMI ($BMI{\leq}85th$ percentile). Six months' intervention included lifestyle-modification counseling (once a week by a clinical dietician), and an exercise regimen twice a week, 60 minutes each time, instructed by a professional pediatric trainer). Both groups underwent baseline measurements at the beginning of the study and 6 months later (arterial stiffness, blood pressure, pulse, weight and height, hemoglobin, creatinine, liver enzymes, highly sensitive C-reactive protein and complete lipid profile). Results: Twenty-one participants completed the study. Low compliance from participants, school staff and parents was observed (participation in planned meetings; 71%-83%). BMI significantly decreased from $32.46{\pm}3.93kg/m^2$ to $30.32{\pm}3.4kg/m^2$ (P=0.002) in the study group. Arterial stiffness was not significantly different between the 2 groups and did not change significantly after 6 months' intervention (P=0.494). No significant changes in CRP and lipid profile were observed after the intervention. Conclusion: Making lifestyle modifications among adolescents in a dormitory school is a complex task. Active intervention indeed ameliorates BMI parameters. However, in order to maximize the beneficial effects, a multidisciplinary well-trained team is needed, with emphasis on integrating parents and the school environment.

Purpose : Adiponectin is an endogenous modulator of vascular remodeling that suppresses vascular inflammation. However, the role of adiponectin in Kawasaki disease (KD) has not been elucidated. The purpose of this study is to investigate the correlation between serum adiponectin level and several parameters, such as interleukin (IL)-6, tumor necrosis factor $(TNF)-{\alpha}$, lipid profile, and C reactive protein (CRP), and to clarify the association between adiponectin and cardiac function. Methods : Twenty-two KD patients (22 patients in acute phase and 20 patients in subacute phase) were enrolled in the study group. The control group consisted of 31 subjects (13 febrile patients and 18 healthy children). Both groups underwent blood sampling and tissue Doppler imaging (TDI). Results : CRP was significantly increased in the KD group compared with the control group. There were no significant differences in serum $TNF-{\alpha}$, IL-6, and adiponectin levels between groups. However, a negative correlation was found between adiponectin level and CRP level or platelet count. Systolic myocardial velocity and A myocardial velocity measured by TDI were decreased significantly in the acute KD group compared with the subacute KD group and control group. Positive correlations were found between adiponectin level and systolic myocardial velocity or A myocardial velocity. Conclusion : In acute KD patients, low adiponectin level was related to severe inflammatory reactions and decreased left ventricular functions.

In the present study, two trials were conducted to evaluate the effects of hyper- and hypothyroid status on the redox balance of broiler chickens. In Trial 1, 3 groups of broiler chickens were randomly subjected to one of the three treatments: subcutaneous administration of triiodothyronine (T3, $150{\mu}g/kg$ BW), methimazole (MMI, 150 mg/kg BW), or saline. The blood, liver and heart were sampled at 3 h after injection. In Trial 2, three groups of 20 broiler chickens were randomly fed with one of the three diets: control, dietary supplementation of T3 (1.5 mg/kg diet) or MMI (1 g/kg diet) for 7 days. In trial 1, the plasma concentrations of T3 and T3 to thyronine ratio (T3/T4) were significantly increased by T3 injection. Plasma levels of thiobarbituric acid reacting substances (TBARS) tended to be increased (p = 0.067) by both T3 and MMI treatments while the ferric reduced/antioxidant capacity (FRAP) was increased only by MMI treatment. Acute T3 treatment had no significant effect on the activities of superoxide dismutase (SOD) and the concentrations of FRAP and TBARS in either liver or heart tissue. In contrast, the hepatic activities of SOD were decreased (p<0.05) while the cardiac levels of FRAP were significantly increased (p<0.0001) by MMI treatment. In chronic treatments, the rectal temperature of chickens was significantly decreased (p<0.05) by MMI treatment. The circulating T3 levels were significantly increased (p<0.05) by long-term T3 treatment, and showed a trend to decrease in MMI treatment. The plasma concentrations of TBARS were significantly (p<0.05) increased by MMI treatment. All the redox parameters measured in either liver or heart were not significantly altered by either long-term T3 or MMI treatment except that the hepatic SOD activities were significantly augmented by T3 treatment. The result showed that neither acute nor long-term elevation of circulating T3 levels induced lipid peroxidation in broiler chickens. The enhanced enzymatic antioxidant system (SOD in cardiac tissue) may be involved in the protection of the bird to increased oxidative challenge. The responses of redox balance to changed thyroid state seem to be tissue specific.

This study was aimed at investigating whether dietary therapy using medicinal enzyme powder is effective in reducing constipation caused by loperamide in rats. Nine-week-old male Sprague Dawley were subdivided into 4 groups: normal diet group (C), loperamide treatment and normal diet (CL), medicinal enzyme powder diet (E), and loperamide treatment and medicinal enzyme powder diet (EL). Constipation was induced by subcutaneous injection of loperamide (1.5 mg/kg) 3 days prior to sacrifice. The treatment with loperamide led to an increase in weight gain, a decrease in the number and wet weight of fecal pellets, and a decrease in intestinal motility. The administration of the medicinal enzyme powder significantly reduced weight gain but increased intestinal mobility compared with the loperamide-treated group. The treatment with loperamide in the normal diet group reduced the activities of both suggesting that constipation may be involved in the low level of glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT). Additionally, the loperamide treatment in the medicinal enzyme powder diet group increased the level of GOT, but reduced the level of GPT. Loperamide treatment also reduced cholesterol and increased the atherogenic index (AI) and cardiac risk factors (CRFs). Interestingly, the treatment with the medicinal enzyme powder effectively attenuated both the increase in AI and the reduction in high density lipopretein (HDL)-cholesterol, caused by the treatment with loperamide. Although there were no significant differences in the blood protein level, including hemoglobin and hematocrit, between the normal diet group and the loperamide-treated group, the administration of the medicinal enzyme powder to the loperamide-treated group effectively increased the levels of both hemoglobin and hematocrit. Collectively, the results demonstrate that the medicinal enzyme powder can help to combat the negative events caused by constipation.

This study was performed to examine the combined effects of gamma linolenic acid and isoflavone supplementation on menopausal symptoms and serum lipids in 73 postmenopausal women. A total subjects were randomly assigned to isoflavone (30 mg) + gamma-linolenic acid (110 mg) group or placebo group. We measured menopausal symptoms by modified Kupperman Index (KI) and oxidized LDL, lipid peroxides, blood components and anthropometric parameters before and after the 12 week intervention period. After the 12 weeks of supplementation, supplement group and placebo group showed a significant reduction of modified kupperman index (p < 0.001). Isoflavone (30 mg) + gamma-linolenic acid (110 mg) supplement group showed a significant reduction of oxidized LDL cholesterol concentration (p = 0.006) whereas placebo group did not show significant change. Isoflavone and gamma-linolenic acid consumption did not significantly affect plasma concentrations of total, LDL, HDL cholesterol, triglyceride, apo A1, B and blood components. The result of present study demonstrated the supplementation of 30 mg isoflavone and 110 mg gamma-linolenic acid per day for 12 weeks may protect LDL cholesterol from oxidative stress.

The aim of this study was to evaluate the biological mechanism of orally administered ethanolic extract of fly maggot(EM) on hypocholesterolemic rats fed a high-cholesterol diet. Sprague Dawley male rats were divided into four groups (EM dose control=0, 5.0, 7.0, and 9.0 mg/100 g BW) and were treated for 6 weeks. EM groups revealed a significant reduction in serum triglyceride, total cholesterol, and LDL-C when compared with the control group(p<0.05). HMG-CoA reductase activity in EM groups were lower than those of the control group, but total sterol, neutral sterol, and bile acid excretion were increased in EM groups when compared with the control group(p<0.05). To identify the biological mechanism of EM towards the hypocholesterolemic effect, sterol response element binding proteins (SREBPs) and the peroxisome proliferator-activated receptors ($PPAR{\alpha}$ transcription system were determined in rats fed a high-cholesterol diet. It was discovered that EM suppress the expression of SREBP-$1{\alpha}$ and SREBP-2 mRNA in the liver tissues of high-cholesterol diet fed rats, while simultaneously increasing the expression of $PPAR{\alpha}$ mRNA(p<0.05). This finding indicates that EM may have hypocholesterolemic effects in rats fed a high-cholesterol diet, by regulating cholesterol metabolism-related biochemical parameters and SREBP-$1{\alpha}$ SREPB-2 and $PPAR{\alpha}$gene expression.

BACKGROUND/OBJECTIVES: Diabetes-specific oral nutritional supplements (ONS) have anti-hyperglycemic effects, while D-allulose exerts anti-diabetic and anti-obesity effects. In this study, we investigated the efficacy and safety of diabetes-specific ONS, including allulose, on glycemic and weight changes in overweight or obese patients with type 2 diabetes mellitus (T2DM). SUBJECTS/METHODS: A single-arm, historical-control pilot clinical trial was conducted on 26 overweight or obese patients with T2DM (age range: 30-70 yrs). The participants were administered 2 packs of diabetes-specific ONS, including allulose (200 kcal/200 mL), every morning for 8 weeks. The glycemic profiles, obesity-related parameters, and lipid profiles were assessed to evaluate the efficacy of ONS. RESULTS: After 8 weeks, fasting blood glucose (FBG) level significantly decreased from 139.00 ± 29.66 mg/dL to 126.08 ± 32.00 mg/dL (P = 0.007) and glycosylated hemoglobin (HbA1c) improved (7.23 ± 0.82% vs. 7.03 ± 0.69%, P = 0.041). Moreover, the fasting insulin (δ: -1.81 ± 3.61 μU/mL, P = 0.017) and homeostasis model assessment for insulin resistance (HOMA-IR) (δ: -0.87 ± 1.57, P = 0.009) levels decreased at 8 weeks, and body weight significantly decreased from 67.20 ± 8.29 kg to 66.43 ± 8.12 kg (P = 0.008). Body mass index (BMI) also decreased in accordance with this (from 25.59 ± 1.82 kg/m² to 25.30 ± 1.86 kg/m², P = 0.009), as did waist circumference (δ: -1.31 ± 2.04 cm, P = 0.003). CONCLUSIONS: The consumption of diabetes-specific ONS with allulose in overweight or obese patients with T2DM improved glycemic profiles, such as FBG, HbA1c, and HOMA-IR, and reduced body weight and BMI.

This study was carried out to investigate the effects of Puerariae Flos extracts on antioxidative potential, free radical generation and the lipid levels in rats. Sprague-Dawley rats were divided into 2 diet groups: AIN-76 diet (control group) and modified AIN-76 diet (cholesterol 0.5%) with 0.5% Puerariae Flos extracts for 4 weeks. Body weight and feed efficiency ratios from both groups were not significantly different. Antioxidative potentials significantly increased in the group fed Puerariae Flos extracts compared to control group (p<0.05). However, there was no difference in free radical generation. The weight of organs, such as heart, kidney, liver, and spleen, in rats were not different in both groups. The ratio HDL cholesterol to total cholesterol in the Puerariae Flos group was significantly higher than in the control group, while the other serum lipid parameters (total cholesterol, HDL cholesterol, triglyceride, and phospholipids) were not different between the two groups. These results imply that supplementation of Puerariae Flos extracts may beneficially contribute to improve antioxidant potential and to decrease the lipid levels in the blood.
