甘味5食材 养肝添活力

中医观点认为,春天养生宜调理肝气,以免因肝气虚出现疲累、口干舌燥、眼睛干涩、情绪低落及抵抗力下降、易反复感冒等问题。春季养生饮食宜少酸多甘,以利脾胃及肝气调理,不妨选择枸杞、韭菜、红枣、紫米、核桃等甘味食物,将其入菜或是泡制、熬煮成茶饮或粥品,帮助补肝血、养肝阴、疏理肝气以及增添活力、抵抗力,而且能润肤、养颜,使气色更红润。     

婴幼儿腹泻六防

婴幼儿腹泻是儿科常见病、多发病,3岁以下的儿童发病率最高,一年四季均可发生,以夏秋两季最严重。由于小儿脏腑娇嫩,抵抗力弱,发生腹泻后病情变化迅速,恢复起来却很缓慢,对婴幼儿的发育影响极大,为此,家长应特别注意对婴幼儿腹泻的预防。     

欧盟欲整顿食品包装及广告中不当宣传用语

为整顿欧盟范围内食品包装及相关广告中不当宣传用语,欧盟委员会5月16日通过一份将于今年12月开始实施的相关产品宣传用语列表。据报道,在欧盟国家部分市场所售食品的包装上和食品广告中,常有某产品“增强机体自然抵抗力”、“促进肠道传输”、“所含钙有助改善骨密度”等表述。

皮肤老化及紫外线防护

皮肤是独特的，其连续的外部覆盖，保护着我们不受毒性环境元素及疾病的侵害。皮肤也是身体抗微生物侵入的自然抵抗力的一部分。然而，除了其自身的著名的屏障特性以外，皮肤自身必须被保护。     

美研究显示：儿童太干净 长大易生病

Finding of Gray Points on the Surface of the Sn-Fe Alloy Layer and Its Effects on the Corrosion Resistance of the Alloy Layer

After removing tin coating of tinplates offered by some steel works, we discovered massive, highly disperse gray points outspreading along rolling direction on the surface of the alloy layer. Morphology of the alloy layer was observed by scanning electron microscope (SEM), and many cavities of the alloy layer were found out in the gray point. After analyzing the composition of the alloy layer, we found that content of Fe in the gray points was more than that in the normal alloy layer. Moreover, corrosion resistance of the alloy layer declines with increase of amount of gray points. In addition, the hot-humidity testing was carried out for some plates whose surface has many gray points. After 14 days, there were many rust points occurring in the edge of gray points and in the small gray points. The morphology of rust points was observed by atomic force microscope (AFM). The reason why rust points generated in the edge of gray points and in the small gray points was discussed.     

Effect of Sn on the Color and Tarnishing of Cu-Mn-Zn Alloys

The effect of Sn on the color and tarnishing of Cu-Mn-Zn alloys is investigated quantitatively. Using the CIE LAB color system, color parameters such as L*, a* and b* are selected to describe the surface color of alloys while the color difference (ΔE*) is used to evaluate the color stability. The results show that with the increase of Sn, the color change of Cu-Mn-Zn alloys is greatly reduced and the corrosion resistance in the synthetic sweat is improved dramatically. However, up to 4.4 wt pct Sn does not change the color of Cu-Mn-Zn alloys much. XPS and AES are employed to analyze the tarnished surface. It is proved that a Sn enriched film is formed and Sn takes the form of Sn oxide. This thin and protective oxide film can prevent alloy from further tarnishing.     

防晒妙方吃也是一种护理

热热闹闹的夏季,恼人的黑斑也跑来凑热闹,想个什么办法赶走它们呢?防晒妙方,吃也是一种护理。食物中的维生素c是抑制黑斑的有效制刺,堪称美白之王。想要修复晒后的皮肤就必须多食用一些含维生素c的水果。另外要想拥有对紫外线防御能力强的肌肤,还须充分摄取防止肌肤老化的维生素E,增加皮肤抵抗力的维生素A,增加皮肤弹性的钙,这些都是抵制黑斑的超级高手。     

复合生物菌和金霉素对肉仔鸡肠道中主要正常菌群影响的研究

研究比较了复合生物菌和金霉素对肉仔鸡肠道中主要正常茵群及抵抗力的影响.试验分饲养试验和攻毒试验.研究结果表明,金霉素显著抑制了大肠杆菌前期的生长,复合生物菌增强了肉鸡肠道正常菌群定植初期的定植抗力,人工感染鸡白痢沙门氏菌后,未饲喂复合生物菌组同饲喂复合生物菌组相比,死亡率提高了20%,大肠杆菌数明显增多,双歧杆菌和乳酸杆菌数明显减少.
