Use crude olive leaf juice as a natural antioxidant for the stability of sunflower oil during heating

Olive leaves (Kronakii cultivar) were obtained from the annual pruning of olive trees and pressed to obtain a crude juice. Aliquots from the concentrated crude olive leaf juice, representing 400, 800, 1600 and 2400 ppm as polyphenols, were added to sunflower oil. Samples of sunflower oil mixed with olive leaf juice were heated intermittently at 180 ± 5 °C for 5 h day^?1 and the heating process was repeated for five consecutive days. A control experiment was performed where butylated hydroxyl toluene (BHT) at 200 ppm was added to sunflower oil prior to intermittent heating in order to compare the antioxidant efficiency between the natural polyphenolics of olive leaf juice and synthetic antioxidant BHT. Some physical and chemical constants for the unheated and heated sunflower oil were determined. The data indicate that the addition of olive leaf juice to sunflower oil heated at 180 °C induced remarkable antioxidant activity and at 800 ppm level was superior to that of BHT in increasing sunflower oil stability.     

橄榄果汁冻干粉的降尿酸与抗痛风作用

采用高尿酸血症大鼠与痛风性关节炎大鼠模型,考察橄榄果汁冻干粉（Hidrox?12%）的降尿酸与抗痛风作用及机制。通过腹腔注射氧嗪酸钾（Potassium oxazinate,PO）建立高尿酸血症大鼠动物模型,灌胃相应药物,检测血清尿酸（Uric Acid,UA）、肌酐（Creatinine,CR）、尿素氮（Blood Urea Nitrogen,BUN）含量和血清与肝脏黄嘌呤氧化酶（Xanthine Oxidase,XOD）活性水平,检测肾皮质尿酸转运蛋白1（Recombinant Urate Transporter 1,URAT1）表达水平。通过给大鼠踝关节腔注射尿酸钠晶体（Monosodium Urate,MSU）建立痛风性关节炎大鼠模型,评价橄榄果汁冻干粉对痛风性关节炎大鼠关节肿胀、血清肿瘤坏死因子α（Tumor Necrosis Factor-α,TNF-α）与白细胞介素1β（Interleukin-1β,IL-1β）水平的影响。通过UPLC-ESI-MS/MS法分离与鉴定降尿酸的有效成分。结果显示,与模型组相比,橄榄果汁冻干粉（80 mg/kg）能极显著降低大鼠血清尿酸水平（P<0.01）,极显著改善高尿酸导致的血清CR与BUN升高（P<0.01）。橄榄果汁冻干粉降尿酸的机制可能与其降低血清和肝脏XOD活性、下调URAT1表达等有关。在痛风性关节炎模型中,橄榄果汁冻干粉（80 mg/kg）能高度显著改善MSU导致的关节肿胀（P<0.001）,显著降低血清TNF-α与IL-1β水平（P<0.05）。进一步研究发现,橄榄果汁冻干粉成分中胡椒碱与木犀草素能有效抑制HEK-293T细胞URAT1的尿酸转运,可能是其降尿酸的活性成分。综上,橄榄果汁冻干粉能有效降低腹腔注射PO导致的高尿酸血症大鼠的尿酸水平,改善大鼠踝关节注射MSU晶体引起的痛风关节炎症状,其机制可能是降低肝脏XOD活性、下调URAT1表达以及改善炎症水平。

Influence of an inhibitor of monoaminooxidase (nialamide) on the serum levels, urinary excretion and plasma clearance of urea, uric acid and creatinine in adult and growing rats

Serum levels, urinary excretion and plasma clearance of urea, uric acid and creatinine were studied in adult (230 g) and growing (75 g) rats under the influence of nialamide (an IMAO) administered in daily doses of 20 mg/100 g diet during 15 or 30 days in adults and 10 mg/100 g diet during 15 days in growing rats. A pair feeding design was used in both ages. Serum levels of urea rose in adult rats fed nialamide for 30 days while urinary excretion decreased. No change in serum levels were noted in growing rats although urinary excretion showed a net increase. Serum uric acid levels were increased in adult female rats given nialamide for 30 days, while urinary excretion fell in both sexes. Growing rats showed a drop in urinary excretion of uric acid. Serum creatinine levels were unchanged in adult and growing rats after treatment with nialamide, although a marked increase was recorded in urinary excretion in both groups.

Lipid compositional changes in calves fed excess iodine

Calves were fed milk replacer containing .57, 10, or 200 ppm iodine (from ethylenediaminedihydriodide) to determine the effects of excess dietary iodine on composition of lipids in blood plasma, liver, and heart. High iodine intakes had no effect on plasma total lipids or lipid classes, but caused lipid class concentration changes in liver and heart. Both 10 and 200 ppm iodine increased concentration of liver phosphatidylethanolamine and heart phosphatidylcholine, cholesterol, and total lipids, and the 200 ppm intake also increased concentration of liver phosphatidylcholine, total lipids, and heart phosphatidylethanolamine. Both iodine treatments tended to increase all the other minor lipid classes in liver and heart as well. Both 10 and 200 ppm iodine treatments increased some of the n-3 polyunsaturated fatty acids in the major phospholipids of plasma, liver, and heart. For the preruminant calf, liver and heart may be more useful than blood plasma for indicating excess iodine effects on lipid metabolism.     

Medical-biological evaluation of genetically-modified sugar beet line 77 (chemical composition and toxicologico-biochemical studies)

The rats were fed with the Genetically Modified Sugar Beet line 77 (Monsanto Ko, USA) 10 g/rat/day for 1 month. Their blood, urea and liver were investigated to measure total protein and glucose levels, aminotransferase and alkaline phosphatase activities, pH, creatinine level as well as hepatic enzyme activity of the I and II phases of xenobiotic metabolism and whole and non-sedimentated lysosomal enzyme activities and activity of antioxidant system.     

Influence of fried and fried‐treated oils with different filter aids on rat health

Soybean, sunflower, palm and cottonseed oils were fried continuously at 180 ± 5 °C for 12 h. Fried oil quality was regenerated by adding individually Magnesol XL, diatomaceous earth and kaolin at 2% level, then stirring mechanically at 105 °C for 15 min and filtering. A set of nutritional experiments was conducted in which rats were administered standard diets containing non‐fried, fried and fried‐treated oils with various filter aids. The safety limits of the fried‐treated oils were recognized by measuring the activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (AP), and levels of total lipids, total cholesterol, HDL cholesterol and LDL cholesterol of rat sera. Also, histopathological evaluation of rat liver tissues was microscopically done to detect any damage that might occur due to feeding rats on non‐fried, fried and fried‐treated oils. Administration of fried oils to rats induced significant rises in activities of ALT, AST and AP, and increases in the levels of total lipids and total cholesterol. The results demonstrate that there were non‐significant changes in sera levels of LDL and HDL cholesterol in rats fed diets containing various types of soybean, sunflower and cottonseed oils. Administration of fried‐treated oils to rat diets indicates that the activities of ALT, AST and AP and levels of sera constituents were similar to those of rats given non‐fried oils. Palm oil exceptionally behaved differently from the other oils. Palm oil raised sera total cholesterol and LDL cholesterol and lowered HDL cholesterol level. Histopathological examination of rat liver tissues indicated that changes paralleled the biochemical data. Copyright © 2006 Society of Chemical Industry     

茶黄素、茶褐素对新慢性高尿酸血症模型小鼠尿酸含量的影响

为研究茶黄素、茶褐素的降尿酸作用。以喂食特制饲料建立新慢性高尿酸血症小鼠模型,连续给小鼠灌胃21 d不同浓度的茶黄素和茶褐素,实验结束断尾取血检测尿酸含量及总胆固醇(TCHO)、葡萄糖(GLU)、甘油三酯(TG)、腺苷酸脱氢酶(ADA)、肌酐(CRE)、丙氨酸氨基转移酶(ALT)、天门冬氨酸氨基转移酶(AST)指标。结果表明,模型组比正常组的血清尿酸含量极显著增高45%(P<0.01),成功建立模型。与模型组相比,灌胃800 mg/kg茶黄素能极显著降低小鼠血清尿酸、AST含量(P<0.01),同时也显著降低了小鼠血清ADA、CRE、ALT的含量(P<0.05);灌胃200 mg/kg茶黄素显著降低了血清ADA、ALT的含量(P<0.05);极显著降低了血清AST含量(P<0.01);灌胃不同浓度的茶褐素对小鼠尿酸含量反而有升高作用,但对小鼠的心脏和肾脏有保护作用。因此,茶黄素对新慢性高尿酸血症小鼠的尿酸含量有明显降低作用,茶褐素对新慢性高尿酸血症小鼠的尿酸含量没有降低效果。

Distribution of olive oil phenolic compounds in rat tissues after administration of a phenolic extract from olive cake

Scope The distribution and accumulation of olive oil phenolic compounds in the body are topics lacked of information. The aim of this study was to evaluate the bioavailability, metabolism and distribution of phenolic compounds from olive cake. Methods and results The metabolism and distribution of phenolic compounds were examined by UPLC‐MS/MS after an acute intake of a phenolic extract from olive cake, analyzing plasma and tissues (heart, brain, liver, kidney, spleen, testicle and thymus) 1, 2 and 4 h after ingestion using Wistar rats as the in vivo model. The results showed a wide distribution of phenolic compounds and their metabolites in the tissues, with a main detoxification route through the kidneys. Highlighting the quantification of the free forms of some phenolic compounds, such as oleuropein derivative in plasma (Cmax 4 h: 24 nmol/L) and brain (Cmax 2 h: 2.8 nmol/g), luteolin in kidney (Cmax 1 h: 0.04 nmol/g), testicle (Cmax 2 h: 0.07 nmol/g) and heart (Cmax 1 h: 0.47 nmol/g); and hydroxytyrosol in plasma (Cmax 2 h: 5.2 nmol/L), kidney (Cmax 4 h: 3.8 nmol/g) and testicle (Cmax 2 h: 2.7 nmol/g). Conclusion After a single ingestion of olive oil phenolic compounds, these were absorbed, metabolized and distributed through the blood stream to practically all parts of the body, even across the blood‐brain barrier.     

冰岛刺参岩藻糖基化硫酸软骨素对高脂饮食诱导的糖尿病小鼠肾脏的保护作用

目的：研究冰岛刺参岩藻糖基化硫酸软骨素（fucolysated chondroitin sulfate from Cucumaria frondosa,Cf-CHS）对高脂饮食诱导的糖尿病小鼠肾脏的保护作用。方法：以高脂高糖饲料饲喂诱导Ⅱ型糖尿病小鼠模型,饲喂含不同剂量Cf-CHS的高脂高糖饲料连续19 周,检测空腹血糖并收集尿液,分别检测小鼠尿液中尿糖、微量白蛋白（microalbumin,mAlb）、尿总蛋白、尿素氮（urea nitrogen,UN）、尿酸（uric acid,UA）、肌酐（creatinine,Cr）浓度和β-N-乙酰葡萄糖苷酶（N-acetyl-β-glucosaminidase,NAG）排泄率,摘取肾脏观察肾脏组织的显微结构。结果：Cf-CHS可显著降低糖尿病小鼠的尿糖、mAlb、尿总蛋白、UN、UA、Cr浓度和NAG排泄率（P＜0.01）,改善肾脏组织的显微结构。结论：Cf-CHS可显著改善糖尿病小鼠的肾脏功能。     

扁舵鲣鱼低聚肽降尿酸功效评价

该研究以高尿酸血症大鼠模型为对象,来评价扁舵鲣鱼低聚肽(Auxis thazard oligopeptide,ATO)降尿酸功效。结果表明,通过对比模型组、ATO 1.6 g/kg、2.4 g/kg剂量组,发现脏器系数并不存在显著差异。血清黄嘌呤氧化酶(xan-thine oxidase,XOD)的变化趋势为先降后升再缓降,据此可以确定,短时间内肝脏中XOD活性能明显降低。对比模型组可以发现,血清尿素氮、血肌酐指标有所下降,ATO 2.4 g/kg剂量组最为明显,血尿酸含量明显下降,差异有统计学意义(P<0.05)。各试验组的尿酸浓度和尿酸排泄量相比正常组也有明显降低(P<0.05)。依据组织病理学结果可知,通过ATO的应用,能够保护高尿酸血症大鼠的肾脏,但剂效关系尚不明显;尿酸生成因尿酸盐沉积的减少而降低,因而ATO具有一定的降尿酸功效,并且不会产生过多的毒副作用。     

Effect of excess dietary manganese on lipid composition of calf blood plasma, heart, and liver.

Preruminant calves were fed milk replacer containing control (40 ppm) or two high concentrations (200 and 1000 ppm) of Mn to assess the effect of excessive Mn intakes on plasma, heart, and liver lipids. The two higher Mn intakes had no effect on lipid classes in liver and heart, except for elevated triglycerides in liver and lower sphingomyelin in heart (for 1000 ppm of Mn). At 1000 ppm of Mn intake, but not at 200 ppm, marked increases occurred in plasma total lipids, phosphatidylcholine, cholesterol, cholesterol esters, sphingomyelin, and triglycerides. The highest intake altered the essential fatty acid composition of liver phosphatidylcholine. Linoleic and linolenic acids were increased, but arachidonic and eicosapentaenoic acids were decreased, suggesting that very high excess of Mn interfered with hepatic desaturation and elongation of the essential fatty acids. Thus, high Mn intake (200 ppm) caused relatively few tissue lipid changes, whereas very high intake (1000 ppm) markedly increased plasma lipid classes and apparently interfered with essential fatty acid metabolism in liver.
