| 1 | Effects of bamboo vinegar powder on growth performance and mRNA expression levels of interleukin-10,interleukin-22,and interleukin-25 in immune organs of weaned piglets显示文摘The aim of this study was to explore the effects of bamboo vinegar powder on growth performance,diarrhea situation and mRNA expression levels of cytokines i.e., interleukin-10(IL-10), interleukin-22(IL-22), and interleukin-25(IL-25) in immune organs of weaned piglets, and to accumulate theoretical data for the application of bamboo vinegar powder in weaned piglet production. Forty-five crossbred(Duroc × Landrace × Yorkshire, all male) weaned piglets with similar body weight(6.74 ± 0.17 kg) at 31 days of age were randomly assigned to 5 treatments with 3 replicates per treatment and 3 piglets in each replicate. The five treatments were as follows: CON(a basal diet), ANT(the basal diet + 0.12% antibiotics),BV1(the basal diet + 0.1% bamboo vinegar powder), BV5(the basal diet + 0.5% bamboo vinegar powder),BV10(the basal diet + 1.0% bamboo vinegar powder). This experiment lasted 35 days. The growth performance and diarrhea situation were recorded. The relative mRNA expression levels of IL-10, IL-22 and IL-25 in liver, spleen, duodenum and mesenteric lymph nodes were detected by real-time PCR. Feed:gain of BV5 was significantly lower than that of CON(P < 0.05). In comparison with CON, diarrhea rate and diarrhea index of BV1 and BV5 all tended to decrease(P < 0.1). Compared with CON, mRNA expression level of IL-10 in liver of ANT tended to be lower(P < 0.1) and these of BV1, BV5 and BV10 were significantly reduced(P < 0.05). The mRNA expression levels of IL-10 in duodenum of ANT, BV1, BV5 and BV10 were all lower than those of CON, of which BV10 had significantly decreased IL-10 mRNA expression in duodenum(P < 0.05). The mRNA expression levels of IL-22 in duodenum of ANT, BV1, BV5 and BV10 all tended to be inhibited compared with CON(P < 0.1). With the increase of bamboo vinegar powder dosage, mRNA expression levels of IL-25 in spleen and mesenteric lymph nodes of BV1, BV5 and BV10 tended to be up-regulated. Overall, bamboo vinegar powder could improve growth performance,and regulate mRNA expression levels of IL-10, IL-22 and IL-25 in immune organs of weaned piglets. The dosage at 0.5% showed optimum effects. | Yongjiu Huo Zhengxu Liu Han Xuan Chunbin Lu Lihuai Yu Wenbin Bao Guoqi Zhao | 2016 | Animal Nutrition2016,,2: | 11 |
| 2 | Synthesis and Surface Active Properties of Cyanuric Chloride-based Branched Surfactant显示文摘A series of novel branched sodium carboxylate surfactants were synthesized from cyanuric chloride, behera amine, alcohol amine and 1,4-Bis (3-aminopropyl) piperazine through seven steps, and the total yield is about 25%. The chemical structures of target products were confirmed by 1H NMR, 13C NMR, FT-IR and ESI-MS. Their critical micelle concentrations (CMC) were also determined by surface tension tests in the aqueous solutions at 22 ℃. The results showed that the CMC value of multi-carboxylate anionic surfactants decreased with the increase of hydroxyl. Additionally, the branched structure of end group can reduce surface tension more than straight-chain type, which was determined by γCMC. The decomposition temperature of the target compound was 250 ℃, which was also tested by TG/DTA curve. | Lv Jinge Lu Chunbin Yuan Cuili Han Jianwei Wang Limin | 2019 | China Detergent & Cosmetics2019,4,2: | 0 |
