A high dietary lipid intake during pregnancy and lactation enhances mammary gland lipid uptake and lipoprotein lipase activity in rats.

Rats fed a diet with high fat concentration produce larger amounts of milk with a higher lipid concentration than rats fed a lower fat diet. This investigation was designed to study the relationship between dietary fat intake, mammary gland lipid uptake and lipogenesis in rat dams fed, during pregnancy and lactation, one of two purified diets, with equal energy density, containing 2.5 (LL) or 20 g fat/100 g diet (HL). Milk lipid concentration and fatty acid composition were determined at d 14 of lactation. Mammary gland lipogenesis, lipoprotein lipase (LPL) activity and the uptake of [1-(14)C]triolein by the mammary gland and its transfer to the pups was measured. The intestinal absorption of oral (14)C-lipid, (14)CO(2) production and the amount of (14)C-lipid transferred to the pups (milk clot + pups carcass) were significantly higher in the HL group than in the LL group (P < 0.05). Mammary gland lipogenesis was 75% lower and LPL activity was 30% higher in the HL group (P < 0.05). Medium-chain fatty acids (C6-C14) excretion was 46% lower and that of long-chain fatty acids was 142% (P < 0.001) higher in the HL group than in the LL group. The higher milk lipid excretion in the rats fed a high-fat diet resulted from a larger uptake of dietary lipid by the mammary gland, indicated by a larger transfer of (14)C-lipid to the pups and by a higher LPL activity in the mammary gland.     

Opposite contributions of trunk and leg fat mass with plasma lipase activities: the Hoorn study

OBJECTIVE: Lipoprotein lipase (LPL) and hepatic lipase (HL) are essential in hydrolysis of triglyceride-rich lipoproteins. LPL activity is negatively, whereas HL activity is positively, associated with total body fat. We determined the associations of trunk and leg fat mass with plasma LPL and HL activities in a cross-sectional study. RESEARCH METHODS AND PROCEDURES: LPL and HL activities were determined in post-heparin plasma in a sample of 197 men and 209 women, 60 to 87 years of age. A total body DXA scan was performed to determine trunk and leg fat mass. RESULTS: In women, but not in men, trunk fat mass was negatively associated with LPL activity, whereas leg fat mass was positively associated, after mutual adjustment and adjustment for age. Standardized betas (95% confidence interval) for trunk and leg fat mass were -0.24 (-0.41; -0.08) and 0.14 (-0.02; 0.31), respectively (interaction by sex, p = 0.03). Larger trunk fat mass was associated with higher HL activity in men [0.48 (0.28; 0.68)] and women [0.40 (0.24; 0.56)]. A negative association of leg fat mass and HL activity was observed in men, although not statistically significant [-0.13 (-0.33; 0.06)], and in women [-0.28 (-0.38; -0.18)]. DISCUSSION: Abdominal fat is associated with unfavorable and femoral fat with favorable LPL and HL activities in plasma.     

健康体检人群高尿酸血症的临床特征及血尿酸与代谢综合征的关系

目的 探讨成年人高尿酸血症(HUA)的临床特征及血尿酸(SUA)水平与代谢综合征(MS)的关系.方法 对≥20岁健康体检者共18 862例的资料进行统计分析.结果 HUA检出率为14.8％(2788/18 862),其中男性为18.4％( 1926/10 445),女性为10.2％( 862/8417);HUA患病率随着年龄的增长而升高,不同年龄段之间比较差异有统计学意义(P=0.000);各年龄段检出率男性均高于女性(P＜0.01或＜0.05).与正常SUA患者相比,HUA患者的体质指数(BMI)、收缩压(SBP)、舒张压(DBP)、总胆固醇(TC)、三酰甘油(TG)、低密度脂蛋白胆固醇(LDL-C)水平均明显增高(P＜0.01或＜0.05),高密度脂蛋白胆固醇(HDL-C)水平则明显降低(P＜0.05).多元逐步回归分析显示:BMI、SBP、DBP、空腹血糖(FPG)、TG、HDLC均是SUA的独立相关因素.HUA患者中高血压、超重/肥胖、血脂紊乱、高血糖及MS的检出率分别为24.1％ (672/2788)、36.2％ (1009/2788)、31.2％(870/2788)、18.0％(502/2788)、20.8％( 580/2788),均显著高于正常SUA患者的18.2％(2925/16 074)、26.4％(4244/16 074)、22.0％(3536/16 074)、15.0％(2411/16 074)、17.0％(2733/16 074)(P＜ 0.01 );SUA在MS患者为(342.3±64.2)μmol/L,明显高于非MS患者的(319.3±67.1)μmol/L,差异有统计学意义(P=0.000).结论 HUA患病率随着年龄的增长而升高,多种代谢异常在HUA患者中呈现聚集倾向,SUA与MS密切相关.     

同等剂量槲皮素、芹菜素对高尿酸血症大鼠的影响及其机制研究

目的研究同等剂量槲皮素(Quercetin,Que)和芹菜素(Apigenin,Api)对腺嘌呤+盐酸乙胺丁醇诱导大鼠高尿酸血症的影响及其机制。方法利用腺嘌呤+盐酸乙胺丁醇片灌胃法诱导SD大鼠制备高尿酸血症模型,槲皮素、芹菜素预防治疗3周,测定血清尿酸(SerumUricAcid,SUA)、血清以及肝脏中的黄嘌呤氧化酶(Xanthine Oxidase,XOD)、腺苷脱氨酶(adenosine deaminase,ADA)的活性。结果槲皮素和芹菜素均可显著降低SUA水平,抑制血清和肝脏中的ADA水平,槲皮素能够显著抑制血清和肝脏中的XOD的活性,但是芹菜素对肝脏XOD活性影响不大。结论槲皮素、芹菜素均有干预腺嘌呤+盐酸乙胺丁醇诱导高尿酸血症的作用。可能的机制是槲皮素通过抑制机体XOD和ADA的活性,减少血尿酸的生成量,从而降低血清尿酸水平;而芹菜素可能通过抑制体内ADA的活性,或许还有别的途径来降低SUA水平,但是具体机制有待于进一步研究。     

红松仁不饱和脂肪酸对肥胖大鼠肝脏脂肪代谢的影响

目的研究红松仁不饱和脂肪酸对大鼠脂肪代谢的调节作用。方法采用从超临界法提取的红松仁油为原料,用尿素包合法制得不饱和脂肪酸。将大鼠随机分为8组,除1组为基础对照组外,其他7组给予高脂饲料,每周称重一次,建立肥胖模型。基础对照组和肥胖对照组分别灌胃生理盐水(1.2g/kgbw),松仁原油对照组灌胃松仁油(1.2g/kgbw),5个剂量组分别灌胃不饱和脂肪酸0.4、0.8、1.2、1.6和2.0g/kgbw。连续4w后,分别测定大鼠体重、脂/体质量比、血清总胆固醇(TC)、血清总甘油三酯(TG)、高密度脂蛋白(HDL-C)、肝脂酶(HL)活性、脂蛋白脂酶(LPL)活性及肝脏脂褐质(LP)含量。结果与肥胖对照组相比,红松仁不饱和脂肪酸能显著降低大鼠体重、脂体比、TG、LP和TC水平,而HL水平和总脂酶(LA)水平显著提高。结论红松仁不饱和脂肪酸对大鼠脂代谢具有积极的调节作用。     

Low-protein diet prevents tissue lipoprotein lipase activity increase in growing rats

The time course of changes in tissue lipolytic activities was studied in young rats during the consumption of a low-protein diet containing 50 g protein/kg (40 g wheat gluten +10 g casein/kg) for 28 d followed by balanced refeeding with 200 g protein/kg (160 g wheat gluten +40 g casein/kg) for 28 d. Lipoprotein lipase (LPL) activities were compared with the values of a control group fed a balanced diet containing 200 g protein/kg for 56 d. At the end of protein malnutrition period, the epididymal fat tissue LPL activity represented 36 %, and that of heart and gastrocnemius was 44 %, of those of the control group. These differences were accompanied by lower serum- and VLDL-triacylglycerols (TAG), respectively 47.6 % and 31 % of the control group values, probably resulting from reduced synthesis of VLDL-apolipoproteins (29 % of control group values), concomitant with liver lipid accumulation (4.8-fold) and little lipid storage in epididymal fat tissue. At day 2 of refeeding, there was no significant difference in liver and epididymal fat tissue LPL activities between experimental and control rats. At the end of the refeeding period, LPL activity of epididymal fat and liver lipolytic activity had increased and became similar to control group values. The consumption of a low-protein diet prevented the increase in extrahepatic LPL activities as observed in the control group. The alterations in LPL activity suggest that a low-protein diet limits lipid storage in adipose tissue due to reduced serum VLDL-TAG availability.     

老年2型糖尿病患者营养不良及腹型肥胖发生率

Effect of antioxidant capacity on blood lipid metabolism and lipoprotein lipase activity of rats fed a high-fat diet

OBJECTIVE: The present study explored the effect of antioxidant capacity on blood lipid metabolism and lipoprotein lipase (LPL) activity of rats fed with a high-fat diet (HFD). Furthermore, the relation of the atherosclerotic index (AI) and LPL activity to total antioxidant capacity (TAC) was studied. METHODS: Thirty-two Sprague-Dawley rats were randomly assigned to one of four groups (n = 8). The control group consumed an ordinary diet (5.1% fat, w/w). The other three experimental groups were fed with an HFD (14.1% fat, w/w), an HFD plus 0.1% lipoic acid (LA), or an HFD plus 0.1% N-acetylcysteine (NAC). After 4 wk, serum levels of triacylglycerol, total cholesterol, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol and LPL activity were examined. To evaluate rats' antioxidant status, TAC and superoxide dismutase activities and malondialdehyde level were measured. RESULTS: The HFD induced abnormal increases in lipid peroxidation, serum concentrations of total cholesterol, triacylglycerol, and low-density lipoprotein cholesterol, and a decrease in high-density lipoprotein cholesterol concentration. Decreased activity of LPL, accompanied by a depressed antioxidant defense system, was observed in HFD-fed rats. These changes were partially restored in the NAC- and LA-treated groups. There was a negative correlation between AI and TAC (r = -0.969, P < 0.05). In addition, a significant positive correlation between LPL activity and TAC was found (r = 0.979, P < 0.05). CONCLUSION: Oxidative injury and lipid abnormalities were induced by an HFD. Administration of LA and NAC can improve the antioxidant capacity and activity of LPL and reduce blood lipid significantly. Antioxidant capacity is correlated with AI and LPL activity.
