海南府城元宵传统的换香习俗,其实源于南北朝演变至宋代的中原元宵习俗,内容包括街巷邻里主动聚合一起放花灯、烟火爆竹、办上元会场、添丁家庭在本境公祠上花灯宴客,还有就是各家各户妇孺和少年男女到户外偷青、赏灯、游城墙、走百病等... 海南府城元宵传统的换香习俗,其实源于南北朝演变至宋代的中原元宵习俗,内容包括街巷邻里主动聚合一起放花灯、烟火爆竹、办上元会场、添丁家庭在本境公祠上花灯宴客,还有就是各家各户妇孺和少年男女到户外偷青、赏灯、游城墙、走百病等,构成互相联系于一体的丰富多彩面貌。并且,因府城自宋代置郡建城,一直作为历朝南方丝路港口都市,既依赖包括民间私运蓬勃所带来的对外经贸繁华,又得应付地方春季气候面临船舰与外商可能带来的各种传染疾病,加上此地本是香料产地,也接近南海各地香料来源,以致现在海口府城不仅延续了上述元宵习俗传统,还形成本地俗称“驳香”的特殊习俗,进一步表达了元宵节强调的驱瘟、添丁与团圆等祈福意愿。当晚,民众从出门到走入城中心,参与上述元宵夜的各种热闹项目,贯穿着一路上遇到他人相互交换香火,互祝“财旺丁旺”的过程,最后又把换回的香插在睡房床下“奶婆炉”,祈求本年添丁、儿女成长成才。全城百姓也由此建构相互认同,意识到他们互相属于海口府城这个由家庭、街坊、城市层层互构的共同体。 展开更多

The effect of ethanol (C2H5OH), propanol (C3H7OH), and butanol (C4H9OH) upon the viscosity of tetradecyltrimethylammonium bromide (TTAB) solution in the presence or absence of KBr at 30℃was investigated, where the surfactant concentration CS is kept constant. In the absence of KBr, the relative viscosity ηr of TTAB solution increases linearly with the alcohol concentration CA, indicating that the alcohols do not promote micelle formation of TTAB. In the presence of KBr, ηr linearly decreases with CA for C2H5OH, but it exhibits a maximum with increasing CA for C3H7OH or C4H9OH. The facts reveal that C2H5OH or C4H9OH promotes the micelle formation of TTAB. A possible explanation is that the hydrophobicity of the mieellar interior is enhanced by KBr, so that C2H5OH or C4H9OH can dissolve in micelle and promotes micelle formation. In the presence of KCl, which is less efficient in promoting the micelle formation of cationic surfactant, both C3H7OH and C4H9OH have only a slight effect on the micelle formation. In contrast, due to the hydrophilicity, C2H5OH cannot dissolve in micelles in the presence of KBr or KCl. 展开更多

AIM To investigate whether gut microbiota metabolite sodium butyrate (NaB) is an effective substance for attenuating non-alcoholic fatty liver disease (NAFLD) and the internal mechanisms. METHODS Male C57BL/6J mice were divided into three groups, normal control were fed standard chow and model group were fed a high-fat diet (HFD) for 16 wk, the intervention group were fed HFD for 16 wk and treated with NaB for 8 wk. Gut microbiota from each group were detected at baseline and at 16 wk, liver histology were evaluated and gastrointestinal barrier indicator such as zonula occluden-1 (ZO-1) were detected by immunohistochemistry and realtime-PCR, further serum or liver endotoxin were determined by ELISA and inflammation-or metabolism-associated genes were quantified by real-time PCR. RESULTS NaB corrected the HFD-induced gut microbiota imbalance in mice, while it considerably elevated the abundances of the beneficial bacteria Christensenellaceae, Blautia and Lactobacillus. These bacteria can produce butyric acid in what seems like a virtuous circle. And butyrate restored HFD induced intestinal mucosa damage, increased the expression of ZO-1 in small intestine, further decreased the levels of gut endotoxin in serum and liver compared with HF group. Endotoxin-associated genes such as TLR4 and Myd88, pro-inflammation genes such as MCP-1, TNF-alpha, IL-1, IL-2, IL-6 and IFN-gamma in liver or epididymal fat were obviously downregulated after NaB intervention. Liver inflammation and fat accumulation were ameliorated, the levels of TG and cholesterol in liver were decreased after NaB intervention, NAS score was significantly decreased, metabolic indices such as FBG and HOMA-IR and liver function indicators ALT and AST were improved compared with HF group. CONCLUSION NaB may restore the dysbiosis of gut microbiota to attenuate steatohepatitis, which is suggested to be a potential gut microbiota modulator and therapeutic substance for NAFLD. 展开更多

Alpinia galanga, Eurycoma longifolia Jack and Syzygium aromaticum have been widely used in traditional medicine for decades. Antimicrobial activities for individual crude extract were well established. Crude methanolic extracts of Alpinia galanga, Eurycoma longifolia Jack and Syzygium aromaticum and the combination for all extracts were tested using well diffusion techniques against Saccharomyces cerevisiae (ATCC 9763) and Escherichia coli (ATCC 25922). The mixed extracts were prepared based on the concentration ratio of 50 μg/μL which are 1:1, 1:1:1 and 1:2:2. Single Syzygium aromaticum extract showed higher inhibition zone on Saccharomyces cerevisiae compared to Escherichia coli. There is reduction in diameter of inhibition zone for single extract and mixture extracts either in combination of two or three extracts tested on Saccharomyces cerevisiae and Escherichia coli growth but they are not significant. In conclusion, Syzygium aromaticum showed highest activity against Saccharomyces cerevisiae and Escherichia coli. Reduction in diameter of inhibition zone indicated that Alpinia galanga and Eurycoma longifolia Jack extracts had antagonistic effect with Syzygium aromaticum. 展开更多

Myrtus communis L. is a spontaneous aromatic plant typical of the Mediterranean area. Myrtle berries hydrodistilled products and ethanolic extracts are mainly used as flavouring agents and food supplements. This study evaluated the effect of long-term storage on the quality-related properties of myrtle berries. Storage at 2 ~C for three months effbctively preserved myrtle berries quality, both in the chemical composition and external appearance. No symptoms of chilling injury and decay occurred during the first two months of storage, at the end of storage only the 1.3% of rotting was detected. Total anthocyanic content and anthocyanin glycosides diminished whereas the antioxidant capacity increased in all samples till the end of storage. The antioxidant properties of myrtle berries were not correlated with the anthocyanic fraction. The pH of myrtle berries decreased, while gluconic acid levels increased. The results reported in this paper showed that the storage at 2 ~C for three months appears to be an effective way to preserve myrtle berries quality. The changes in the chemical composition of the fruits subjected to storage had revealed the importance of gluconic acid and pH for myrtle quality assessment. These two parameters can be used as quality markers since a strong relationship has been found between myrtle decay and the changes in these parameters, 展开更多
