Surveys of 28 children have shown that 64 per cent of the children suffering from ulcerous disease of the stomach and the duodemun or chronic duodenitis have a combined deficiency of vitamin E, vitamins of the B group and beta-carotene. Diet No. 1 and No. 5 could not provide daily needs for vitamins. The patients were found to have a lower antioxidant activity of the blood serum, whereas the contents of hydroperoxides, double bonds and malonic dialdehydes were higher than in healthy children. The POL index in children with high beta-carotene deficiency was significantly higher than that in ailing children supplied with this carotenoid. Correlation analysis has revealed a reverse relationship between concentration of vitamin E and beta-carotene in blood serum and POL products, i.e. the better a child is supplied with these vitamins, the lower is the level of POL products. When the drink with the whole set of vitamins and an oil solution of beta-carotene was included in the diet of the children, it was found that hypovitaminosis frequency lowered with positive effects on their clinical condition and improved POL indexes. So there is a reason to fortify diets of children suffering from gastrointestinal disorders with vitamins-antioxidants. 相似文献

为了探讨在气动加压摇架V型牵伸细纱机上实施重定量、大牵伸生产工艺的效果,分析了其机理并通过在FA506型细纱机上使用创新型牵伸元件,优选细纱牵伸工艺参数纺R/T 60/409.8tex纱实践,从减小前纺设备配置,节约用工及产品质量3个方面对其应用效果进行了评估。试验表明在满足成纱质量的前提下,气动加压摇架V型牵伸细纱机纺R/T 60/40 9.8tex纱完全具备采用重定量大牵伸生产工艺的基本条件,粗纱定量可由2.8g/(10 m)增至5.1g/(10 m),且对成纱条干质量和常发性纱疵的改善均十分有利;虽然实施5.1g/(10 m)重定量生产工艺的条干CVb值和平均强力下降,有害毛羽明显增多,但是通过合理调整粗纱定量和细纱总牵伸倍数,也能够生产市场要求较高的纱线品种。指出在FA506型气动加压摇架V型牵伸细纱机上采用较大的粗纱定量,在减少前纺设备开台、节约生产用工、节能降耗、提高生产效率方面能够发挥较显著的作用。 相似文献

0 前 言随着人民生活水平的提高 ,各种以肉类原料为基础的灌制品已经成为我国人民经常食用的食品。肉灌制品有中式和欧式的区别 ,传统的香肠、香肚、小肚和从欧州引进的红肠、茶肠等已在我国大量生产。风味各异的肉灌制品的加工工艺不同 ,配料也各有千秋 ,但其风味的主要来源是依靠各种香辛调味料 ,除了葱、蒜、生姜、洋葱等各种生鲜植物可作为香辛调味料外 ,各种“干调”香辛料在肉灌制品生产中广泛使用 ,本文介绍的即为这类香辛调味料。1 大茴香又名八角茴香、大料 ,是木兰科植物八角茴香的果实 ,常绿乔木。我国福建、广东、广西、云… 相似文献

研究了免疫接种次数对免疫乳中特异性抗体效价的影响。以9株人肠道病原菌制备的混合抗原对孕牛进行系统免疫,其中对照组免疫接种4次,实验组免疫接种6次,分娩后收集乳样,检测其中特异性抗体的效价。结果表明,实验组和对照组初乳中抗体效价无统计学意义,均达到210~212;而常乳中特异性抗体效价有统计学意义:对照组效价平均为25~26,实验组效价平均为26~27,并且随着时间的推移差异越来越显著。结论:选择好免疫接种的间隔时间,并进行多次接种,能使免疫乳中特异性抗体效价在长时间内保持较高水平。 相似文献

The reaction of arginine and arginine derivatives with glyoxal under mild conditions revealed the formation of a previously
unknown amino acid, designated as “Glarg”. 1H-, 15N- and 13C-NMR analysis of the new compound elucidated its structure to be 1-(4-amino-4-carboxybutyl)-2-imino-5-oxo-imidazolidine.
Experiments with solutions containing N
α
-acetylarginine and glyoxal showed that “Glarg” is formed quickly under physiological conditions, but is labile at higher
temperatures as well as at low pH values. After incubation of β-casein with glyoxal, the formation of protein-bound “Glarg”
in enzymatic hydrolysates via amino acid analysis could be demonstrated. Due to the fast reaction of glyoxal with arginine
residues, under physiological conditions, proteins may act as scavengers for glyoxal.

用沸点酒精测定仪法可测定葡萄酒的酒度。在这种分析方法中,葡萄酒可简单地看成酒精与水的混合物,葡萄酒的酒度与大气压及其本身所含酒精有关,通过测定水、酒的沸点,即可得到酒精度令量。沸点测定仅价格便宜,测定准确,操作方便,有一定的使用价值。 相似文献

本文探讨了催化剂的种类、次氯酸钠的用量和反应时间对芭蕉芋淀粉氧化反应的影响.结果表明:氧化淀粉中的羧基随次氯酸钠的用量和反应时间的增加而增加,但粘度不断下降.有效氯为2%时,淀粉中羰基含量最高.使用催化剂A可制备羧基和羰基含量都较大的氧化淀粉,使用KI则可制备羧基少而羰基含量高的氧化淀粉. 相似文献
