The objective of this study was to investigate the effects of dietary bamboo leaf extract (BLE) on antioxidant status and cholesterol metabolism in broilers. One-day-old male Arbor Acres (576) broilers were randomly divided into six groups. A control group was fed a basal diet, while five experimental groups were supplemented with 1.0, 2.0, 3.0, 4.0, and 5.0g BLE per kg feed in their basal diets. The result indicated that BLE supplementation linearly improved eviscerated yield and decreased abdominal fat (p < 0.05). A significant decrease of serum triglyceride (TG) and low-density lipoprotein cholesterol (LDL-c) content was observed with BLE supplementation (p < 0.05). BLE supplementation linearly improved the total antioxidant capacity and catalase activity in both serum and liver (p < 0.05). Glutathione peroxidase was quadratically increased in serum and linearly increased in the liver with BLE supplementation (p < 0.05). The malonaldehyde content in liver showed a linear and quadratic decrease with BLE supplementation (p < 0.05). BLE supplementation up-regulated the mRNA expression of cholesterol 7- alpha hydroxylase and low-density lipoprotein receptor and downregulated 3-hydroxy3-methyl glutamates coenzyme A reductase mRNA expression in the liver. The antioxidant enzyme mRNA expressions were all up-regulated by BLE supplementation in the liver. In conclusion, supplemental BLE improved antioxidant status and cholesterol metabolism in broilers, which eventually led to a decrease of serum TG, LDL-c content, and abdominal fat deposition.

Abstract Objectives Ocimum gratissimum L. is used in traditional medicine for the treatment of bacterial infections and anaemia. This study was designed to evaluate the effect of O. gratissimum leaf extract on phenylhydrazine (PHZ)-induced anaemia and toxicity in rats. Methods The experimental rats were divided into five groups (A–E) (n=6/sex/group). Each rat in groups B–E was intraperitoneally administered 50 mg/kg of PHZ for two consecutive days. Group A (normal control) did not receive any PHZ, group B (negative control), group C received orally 5 mg/kg ferrous sulphate whereas groups D and E received 200 and 400 mg/kg O. gratissimum leaf extract respectively, for 14 days. Results Red blood cell count, packed cell volume, haemoglobin concentration and high-density lipoprotein increased significantly (p<0.05) whereas low-density lipoprotein and very-low-density lipoprotein decreased in extract-treated groups when compared to the negative control. O. gratissimum (400 mg/kg extract) and standard drug (5 mg/kg ferrous sulphate) significantly (p<0.05) reduced the levels of aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase. Conclusions The results of this study indicate that O. gratissimum leaf extract has a restorative effect on the phenylhydrazine-induced metabolic distortions in the blood, liver, and kidney, and therefore could be used therapeutically as an anti-anaemic tonic.

ABSTRACT While there is strong evidence showing that many food-borne probiotics regulate cholesterol metabolism, few studies have examined how probiotics of human origin affect cholesterol metabolism. Because people living in so-called ‘longevity villages’ are unlikely to have hypercholesterolemia, we hypothesized that probiotics isolated from the residents would have cholesterol-reducing effects on rats with hypercholesterolemia. We isolated 16 strains of Lactobacillus from four longevity populations in China. The strains were tested in vitro for bile salt hydrolase (BSH) activity and two isolates, Lactobacillus reuteri A9 and Lactobacillus mucosae A13, were screened out. These two strains were then administered daily for 28 d to rats fed a cholesterol-rich diet. The serum total cholesterol levels in the L. reuteri A9 and L. mucosae A13 groups decreased by 24.3% and 21.6%, respectively. The serum low density lipoprotein cholesterol levels decreased by 23.8% and 25.2%, respectively. The L. reuteri A9 and L. mucosae A13 groups also exhibited upregulated hepatic mRNA expression of Sterol regulatory element-binding protein 2 (Srebp2) by 2.71-fold and 2.54-fold, respectively. The mRNA expression levels of hepatic low-density lipoprotein receptor (Ldlr) in the two groups were significantly up-regulated by 1.28-fold and 2.17-fold, respectively. The composition of gut microbiota was recovered by oral gavage in both experimental groups, and the destroyed diversity of gut microbiota was relieved.

The experiment was performed to determine the effects of alfalfa saponin extract (ASE) on the performance and cholesterol metabolism of laying hens. A total of 150 Hy-Line Brown hens with 28 weeks old, were randomly divided into five treatment groups (five replicates per treatment with six hens per replicate). Diets containing 0, 60, 120, 240, and 480 mg ASE/kg were fed to hens for 77 days. The shell thickness had a trend to increase. The yolk cholesterol and liver bile acid decreased significantly (ASE 60 and 480 mg/kg groups for yolk cholesterol, and ASE 60 and 240 mg/kg groups for liver bile acid). Fecal bile acid has an elevation trend as ASE increased. The expression of very low density apolipoprotein-Ⅱ (apoVLDL-Ⅱ) gene was not affected by adding ASE. However, the mRNA expression of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase gene and cholesterol 7α-hydroxylase (CYP7A1) gene were significantly up-regulated. The mRNA expression of very-low-density-lipoprotein receptor(VLDLR) gene was suppressed due to adding ASE supplementation in the diet. These findings indicated that dietary ASE could regulate cholesterol levels in hens by up-regulating the mRNA levels of HMG-CoA and CYP7A1 and suppressing the expression of VLDLR.

BACKGROUND AND AIMS: This study was designed to determine whether the haptoglobin levels are comparable to the antioxidant status levels. 40 athletes and 30 volunteers were enrolled in the study. MATERIAL AND METHODS: Blood samples for serum malondialdehyde (MDA), total antioxidant status (TAS), haptoglobin, glucose, total cholesterol (TC), triglyceride (TG), very low density lipoprotein cholesterol (VLDL-C), low density lipoprotein cholesterol (LDL-C) and high density lipoprotein cholesterol (HDL-C) and lipoprotein (a) (Lip a) determinations were obtained before and after cyclists completed 300 km bicycle ride. RESULTS: Comparison of the results between the cyclists and control group yielded a signicant difference in serum levels of TG, VLDL-C and LDL-C (P<0.05). The cycling induced a signicant increase in HDL-C, VLDL-C, TG, MDA and TAS levels (P<0.001). Serum LDL-C and Lip a levels were greater before than after cycling (P<0.05). There was no signicant difference among precycling and postcycling haptoglobin levels, whereas the haptoglobin level in control group was signicantly higher than in the cyclists (P<0.001). CONCLUSION: The change in serum antioxidant and lipid levels due to physical activity must be explained as a consequence of the duration of exercise. Further studies are needed to demonstrate haptoglobin's possible role in decreasing oxidative stress during exercise.

Abstract Background: Pancreatic cancer (PC) is one of the most aggressive and lethal malignancies in the world. High cholesterol intake may have a certain association with an elevated risk of PC, though dyslipidemia in PC patients has rarely been reported. In this study, we compared serum lipids levels between PC and non-PC tumor patients and assessed their prognostic value in PC. Methods: 271 patients treated at Wuhan Union Hospital from January 2012 to December 2016 and 204 individuals at Shanghai General Hospital from January 2018 to December 2019 were recruited. Their demographic parameters, laboratory data, pathological information, and clinical outcomes were extracted and analyzed. The mRNA expressions of related lipoprotein, low density lipoprotein receptor (LDLR) and high density lipoprotein binding protein (HDLBP), in PC tissues and paired noncancerous tissues and follow-up information were assessed based on the GEO database (GSE15471 and GSE62165) and TCGA database. Results: A total of 172 non-PC tumor patients and 260 PC patients were finally eligible for our analysis. PC patients exhibited higher levels of serum triglyceride, cholesterol, and low-density lipoprotein (LDL) and a lower serum high-density lipoprotein (HDL) level on admission versus the non-PC tumor group. In PC patients, LDLR mRNA expression was upregulated, and HDLBP mRNA expression was downregulated in cancerous tissues compared to these levels in paired noncancerous tissues. The survival analysis revealed that dyslipidemia had a non-significant association with a poor prognosis, but PC patients with a high LDLR level were at risk of poor survival. Conclusion: Dyslipidemia is detected in PC patients but has a non-significant relation to PC prognosis. However, LDLR may be a potential predictive marker for PC prognosis.

Context: Subclinical hypothyroidism (SCH) and metabolic syndrome (MetS) increase with age; however, their relationship remains unclear. Objective: Our objective was to investigate the relationship between SCH and indices of metabolic syndrome and follow up subjects for 1 year. Design: Cross-sectional and longitudinal follow-up studies of cases were collected from Takasaki Hidaka Hospital between 2003 and 2007. Participants: Overall, 11 498 participants of health checkups were analyzed. The mean age was 48 ± 9 years. Main Outcome Measures: The relationship between SCH and indices of MetS were examined. Results: Serum free T4 levels were lower in women than men in most of the age groups, and the prevalence of SCH, 6.3% in women vs 3.4% in men, increased with age, reaching 14.6% in 70-year-old women. Multivariate logistic-regression analyses revealed that waist circumference and the serum triglyceride and low-density lipoprotein-cholesterol levels were significantly higher in subjects with SCH than without among women. Reflecting these findings, the adjusted odds ratio of MetS in patients with SCH was higher than in the euthyroid subjects in women with an odds ratio of 2.7 (95% confidence interval 1.1–5.6; P = .017) but not in men. Furthermore, progression from euthyroid into SCH resulted in a significant increase in the serum triglyceride levels but not low-density lipoprotein-cholesterol in women. Conclusion: Japanese women exhibited a high prevalence of SCH associated with low free T4 levels. There was a strong association between SCH and several indices of metabolic syndrome in women. SCH may affect serum triglyceride levels and be a risk factor for metabolic syndrome.

SummaryInflammatory responses and cholesterol homeostasis are interconnected in atherogenesis. Interleukin (IL)-10 is an important anti-inflammatory cytokine, known to suppress atherosclerosis development. However, the specific cell types responsible for the atheroprotective effects of IL-10 remain to be defined and knowledge on the actions of IL-10 in cholesterol homeostasis is scarce. Here we investigated the functional involvement of myeloid IL-10-mediated atheroprotection. To do so, bone marrow from IL-10 receptor 1 (IL-10R1) wild-type and myeloid IL-10R1-deficient mice was transplanted to lethally irradiated female LDLR-/- mice. Hereafter, mice were given a high cholesterol diet for 10 weeks after which atherosclerosis development and cholesterol metabolism were investigated. In vitro, myeloid IL-10R1 deficiency resulted in a pro-inflammatory macrophage phenotype. However, in vivo significantly reduced lesion size and severity was observed. This phenotype was associated with lower myeloid cell accumulation and more apoptosis in the lesions. Additionally, a profound reduction in plasma and liver cholesterol was observed upon myeloid IL-10R1 deficiency, which was reflected in plaque lipid content. This decreased hypercholesterolaemia was associated with lowered very low-density lipoprotein (VLDL) and low-density lipoprotein (LDL) levels, likely as a response to decreased intestinal cholesterol absorption. In addition, IL-10R1 deficient mice demonstrated substantially higher faecal sterol loss caused by increased non-biliary cholesterol efflux. The induction of this process was linked to impaired ACAT2-mediated esterification of liver and plasma cholesterol. Overall, myeloid cells do not contribute to IL-10-mediated atheroprotection. In addition, this study demonstrates a novel connection between IL-10-mediated inflammation and cholesterol homeostasis in atherosclerosis. These findings make us reconsider IL-10 as a beneficial influence on atherosclerosis.Supplementary Material to this article is available online at www.thrombosis-online.com.
