Optimization of Lubricant Type and Amount in Inulin Compound Effervescent Tablets Using Orthogonal Test

It is to study the preparation process of inulin compound effervescent tablets by single factor experiments and optimize the type and amount of lubricants. The formula of the pH, effervescent time, sensory quality and stiffness were selected as the evaluation index. Meanwhile, the orthogonal tests were used to optimize the ratio of citric acid to sodium bicarbonate, the amount of sweetener and the amount of orange powder. The best preparation technology conditions of effervescent tablets were as follows: the ratio of citric acid to sodium bicarbonate 1.25︰1, inulin 27.8%, stevia 1%, orange powder 20%, PEG- 6000 1.6% and sodium chloride 3.4%. Under the optimal conditions, there was no sticking phenomenon during tablets preparation. Furthermore, all the quality indexes of the prepared effervescent tablets complied with the requirements of the “Chinese Pharmacopoeia”

Effects of Jerusalem artichoke powder on growth and immune responses after Vibrio splendidus infection in sea cucumber Apostichopus japonicus

The experiment was conducted to study the effects of Jerusalem artichoke powder on the growth performance of Apostichopus japonicus and variation of immune-related enzyme activities after Vibro Splendidus infection.Three hundred and sixty sea cucumbers with initial body weight(4.7±0.1)g were randomly divided into three treatments.Control group was fed basal diet while treatment groups were fed basal diet supplemented with 5,15 g/kg Jerusalem artichoke powder for 42 d.The farming stage was 0 ～ 28 d while the infection stage was 29 ～ 42 d.The results showed as follows:(1) Compared with control group,the feed conversion ratio(FCR) of group Ⅱ was significantly increased by 21.05%(P 0.05).(2) Supplementation of 15 g/kg Jerusalem artichoke powder significantly improved the activities of acid phosphatase(ACP),alkaline phosphatase(AKP) and superoxide dismutase(SOD) after Vibrio splendidus infection(P < 0.05).In addition,5 g/kg Jerusalem artichoke powder significantly improved the activity of lysozyme(LYZ)(P < 0.05) at the early days of bacterial infection.According to the results,15 g/kg Jerusalem artichoke powder significantly improved the activation of four immune enzymes after Vibrio splendidus infection

固体贝壳粉涂料的制备及其吸附甲醛性能优化

Shell powder is not only a kind of natural resources but also has a very good application value. It has a strong adsorp tion, antibacterial and fireproof ability, which could significantly improve the performance of the coating while added to the coating. In this paper, a kind of solid shell powder coating was prepared and its effect on formaldehyde adsorption was studied. Taking formalde hyde adsorption content as the index, response surface methodology (RSM) was employed to optimize the main process parameters (shell powder dosage, gelatin dosage and lithopone dosage) and investigate the regression model. The results of variance analysis showed the regression model reflected the effect of shell powder, gelatin and lithopone on formaldehyde adsorption. The optimum condi tions were obtained as follows: shell powder 60 g, lithopone 12 g, gelatin 6 g. Under these optimized conditions, the adsorption formal dehyde content of the coating was 5. 87 g / kg.</p

基于公共基因芯片的多农药代谢相关的拟南芥ugt基因挖掘

糖基转移酶1家族,也称尿苷二磷酸糖基转移酶(Uridine diphosphate glycosyltransferase,UGT),是植物解毒系统中最重要的多基因家族之一。该研究基于公共基因芯片数据对拟南芥(Arabidopsis thaliana)的106个UGT基因进行生物信息学分析,期望找到参与广谱农药代谢的UGT靶标。从NCBI数据库收集并重注释关于农药和除草剂安全剂处理的基因芯片数据,差异表达分析和聚类分析表明8个UGT在绝大部分农药处理中均显著转录上调,是重要候选基因。基因本体论(Gene ontology,GO)富集分析表明,候选UGT的共表达基因富集于植物4相代谢解毒过程,暗示这些UGT基因的广谱解毒能力。最后以候选UGT基因及其共表达基因构建共表达网络,发现网络中的桥接节点也参与了植物解毒过程,表明UGT76B4和UGT76B5是最关键的参与多种农药代谢的UGT基因

黄土区切沟对不同植被下土壤水分时空变异的影响

为掌握切沟对土壤水分时空变异的影响，选取水蚀风蚀交错区两个典型切沟样点为研究对象。采用时间序 列分析和经典统计学方法，从土壤水分时间变化特征和空间分布格局两方面探讨。结果表明: 距沟道不同距离下 土壤储水量差异明显。300 cm 处样点可作为测定尺度下土壤储水量平均值。土壤水分在垂直方向上的变异受植被 特征影响，沟道影响较小。坡面土壤储水量的空间分布呈现不同的分布格局。坡顶风速大，土壤水分蒸发快，坡 中处土壤储水量最高，为949. 9 mm，距切沟越近土壤水分快速散失，坡下土壤水分接近4%，亏缺严重。杏树地土 壤储水量远高于柠条地，柠条地土壤储水量分布较为单一。土壤蒸发、植被、沟道等因素使得坡面土壤水分分布 更加复杂

ffect of wheat aleurone layer on serum lipid level and insulin resistance in rats with high fat diet

The effects of wheat aleurone layer on blood lipid level and insulin resistance in rats with highfat diet were studied. The rats were administered by gavage with aleurone layer for 5 successive weeks. Compared with the control group, the rats in the wheat aleurone layer group were significantly reduced in weight gain(P <0.05) and the food intake was also reduced. Serum levels of TC, TG and LDL-C were significantly decreased, while HDL-C significantly increased(P<0.05). Meanwhile, the blood lipid ratio TC/HDL-C, TG/HDL-C, LDL-C/HDL-C and AI levels were improved. Serum FBG, HOMA-IR(P<0.05), ISI, and HOMA-β index were significantly reduced while T-SOD levels increased significantly(P<0.05) by aleurone layer intervention, which could alleviate insulin resistance in rats with high-fat diet. The liver body ratio and liver fat accumulation with wheat aleurone layer intervene was significantly reduced. The results showed that aleurone layer can interfere with high-fat diet, play a role in reducing blood lipid, alleviating insulin resistance, improving liver fat accumulation, and reduce the occurrence of related diseases
