江南水乡妇女首服的形制与渊源

 运用了民俗学和服装学的原理,对江南水乡妇女的发型、眉勒、包头巾、簪花的形制与渊源作了初步研究。其中发型是蓄发并有发髻,同时伴有簪花,这是构成水乡妇女首服的基础,眉勒是系扎于前额的狭长形条带,包头巾是包裹头顶的梯形布幅,这是构成水乡妇女首服的主体。这一切都具有悠远的历史渊源,同时与当地“稻作文化”的生活形态密切相关。

Tenderness and oxidative stability of post-mortem muscles from mature cows of various ages

Two experiments were conducted to investigate the influence of age of mature cows (2-4yr, 6-8yr, and 10-12yr cows; n=6 in each) on beef quality. In Experiment 1, Longissimus dorsi (LD) steaks were stored at 3°C for 0-10d. Steaks from more mature cows had an increased (P<0.05) Warner-Bratzler shear force (WBSF) and a slower troponin-T post-mortem degradation. Storage reduced WBSF in all steak samples regardless of animal age. In Experiment 2, Semitendinosus (ST) and Semimembranosus (SM) patties were stored at 3°C for 0-7d simulating retail display. The rate of lipid oxidation during storage increased with animal age (P<0.05) and was greater in ST than in SM patties. However, myoglobin oxidation was minimally affected by animal age. Thus, advanced maturation not only intensified cow meat toughness but also lowered its oxidative stability.     

尿素包合法纯化红花籽油中亚油酸

本文介绍了以尿素包合法纯化红花籽油中亚油酸的方法。作者对多不饱和脂肪酸的制备及尿素包合法纯化其中亚油酸的工艺进行了研究，重点考察了溶液中尿素浓度（尿素／甲醇，w／v）、待富集混合物中亚油酸含量与尿素溶液的用量（w／v）之间的关系对富集效率的影响。结果表明，当尿素溶液浓度为1／5、尿素甲醇溶液用量与混合脂肪酸中亚油酸含量的比例为10．0，在-10℃保存24h后，所富集后亚油酸纯度可以提高到95．66％，回收率可以达到93．58％。

松口蘑糖蛋白联合5-Fu体外对人肝癌细胞Bel-7402的影响及作用机理初探

采用MTT法研究了松口蘑抗肿瘤糖蛋白MTS03与化疗药物5-Fu单独及联合使用对人肝癌细胞Bel-7402的影响及对人正常肝细胞L-02的毒性作用，观察不同浓度配比及不同作用时间对细胞是否具有增效减毒的作用；采用扫描电镜观察MTS03作用后的Bel-7402细胞形态．结果表明，MTS03与5-Fu在较低浓度单独使用对肿瘤细胞无显著差异，但两者联合使用增强了对肿瘤细胞的杀伤作用，而对正常细胞的作用较小，联合使用的q值均大于0．85，说明不存在拮抗作用．扫描电镜观察到凋亡小体的形成，随着剂量升高，凋亡小体增多．这一结果说明两者合用后MTS03增加了5-Fu对肝癌细胞的敏感性，同时降低了两者单一高剂量使用时引起的毒副作用，同时MTS03能诱导Bel-7402细胞膜皱缩和凋亡小体的形成．     

猪血G型免疫球蛋白稳定性研究

研究了酸性环境和加热对猪血IgG活性的影响。结果显示猪IgG热变性的温度范围为70.265~72.162℃,吸热量为338.4J/g。室温时,pH降低到4以下IgG开始变性,其活性损失随pH的下降而增加。pH为7时,60℃后IgG开始变性,随温度升高活性损失越来越大。酸性条件下免疫球蛋白对于温度更为敏感,较低的温度就会造成IgG的变性。     

Antioxidant activity of feruloylated oligosaccharides from wheat bran

Ferulic acid, the main phenolic acid in wheat bran, is esterified to arabinose residues in the cell wall arabinoxylan. Treatment of wheat bran insoluble dietary fibre with xylanases from Bacillus subtilis released feruloylated oligosaccharides, which were purified with Amberlite XAD-2. The antioxidant activity of such oligosaccharides was evaluated using the assay system for erythrocyte hemolysis mediated by peroxyl free radicals generated from 2,2^′-azobis-2-amidinopropane dihydrochloride (AAPH) under in vitro conditions. The feruloylated oligosaccharides inhibited hemolysis of erythrocytes in a dose-dependent manner with 91.7% inhibition of erythrocyte hemolysis at 4 mg/ml.     

膨化陈糙米及添加淀粉酶对断奶仔猪消化及生产性能的影响

本试验研究了陈糙米日粮是否膨化和是否添加外源淀粉酶两个因素,对26日龄断奶仔猪小肠黏膜二糖酶活性、血液葡萄糖和尿素氮含量、生产性能的影响.试验28d的结果表明,陈糙米日粮经膨化后能提高断奶仔猪十二指肠黏膜中二糖酶的活性,但降低了空肠黏膜中二糖酶的活性,采食膨化料的仔猪生产性能低于未膨化料的,但差异不显著.添加外源酶可以提高十二指肠和空肠黏膜中部分二糖酶的活性,但对仔猪的生产性能并未有显著改善.膨化和加酶及其交互作用对仔猪血清中葡萄糖和尿素氮含量并无显著影响（P＞0.1）.
