    • 摘要: 竹红菌素是具有抗肿瘤、抗病毒活性的光敏性苝醌类化合物,分离自我国传统的药用真菌——竹黄菌子实体和菌丝。竹红菌素作为非卟啉类新型光敏剂,已应用于肿瘤、真菌疾病的光动力治疗(photodynamic therapy,PDT)中。近年来,微粒促进培养(MPEC)技术在真菌发酵培养和生产中受到了广泛关注,笔者在竹黄菌种子培养期加入竹炭微粉(BCP)(2 g/L)处理,竹黄菌胞内竹红菌甲素(HA)含量和胞外HA产量在3 d后分别增加了63.0%~64.9%和63.5%~147.4%,发酵8 d后,HA总产量可达604.8 mg/L,是对照组的1.65倍。进一步在生产发酵阶段加入Triton X-100(25 g/L)进行萃取发酵,将胞内HA萃取到胶束溶液中,浊点系统的形成可简化HA的提取过程,提高生产效率。本研究为真菌苝醌类光敏药物生产提供了新型的萃取发酵技术。

    • 摘要: To compare the physicochemical properties and blood compatibility of two kinds of acellular vascular stents prepared by traditional Triton-x100 method and salvianolic acid B with Triton-x100. To explore the prospect of the application of salvianolic acid B post-treated acellular vascular stents in the treatment of cardiovascular and cerebrovascular diseases and the development of tissue engineering vascular materials. A total of 16 SD rats, male and 7 weeks old, with a mass of 250 g, were included and randomly divided into 2 groups, 8 in each group. Two kinds of acellular vascular scaffolds prepared by Triton-x100 method (Tx group) and Triton-x100 adding salvianolic acid B method (Tx-sal group) were implanted. The macroscopical morphology, hydrophilicity, in vitro hemolysis rate and the determination of coagulation time of complex calcification were investigated. The blood compatibility of two groups of acellular scaffold was compared on the basis of a series of experiments. The contact angle of Tx group was (76.36±4.647), Tx-sal group was (71.26±3.553), and Tx group was slightly higher than Tx-sal group, which didn′t have significant difference in statistics. Hemolysis rate in the group of Tx-sal was 1.5% and hemolysis rate in the group of Tx was 2.1%. The coagulation time of recalcification in Tx group was (212±11.32) s, and that of Tx-sal group was (231±13.53) s. There was significant difference in the coagulation time between Tx group and Tx-sal group. Group Tx-sal had delayed coagulation time and had better anticoagulation when compared with group Tx. The platelet count in the group of Tx-sal was lower than that in the group of Tx. The level of complement activation was lower in the group of Tx-sal. In conclusion, the acellular scaffold with salvianolic acid B had better blood compatibility than the acellular scaffold prepared by traditional Triton-x100 method.%应用传统的Triton-x100法与应用Triton-x100和丹参酚酸B法制备脱细胞血管支架, 比较这两种支架的理化性质及其血液相容性, 展望应用丹参酚酸B后处理脱细胞血管支架在临床上治疗心脑血管疾病方面的应用前景, 以及在组织工程血管材料方面的开发空间.选择SD大鼠16只, 雄性, 鼠龄7周, 体质量250 g左右.解剖大鼠, 取腹主动脉;随机分为2组, 每组8个.用Triton-x100法 (Tx组) 、Triton-x100加入丹参酚酸B法 (Tx-sal组), 加工制成两种脱细胞血管支架.观察脱细胞血管支架的宏观形貌;亲水性实验测定亲水性;体外溶血实验计算体外溶血率;复钙化凝血时间实验测定复钙化凝血时间;血小板黏附实验测定动态凝血时间, 以及体外血小板的黏附;补体激活实验测定补体激活程度情况;比较两组脱细胞血管支架的血液相容性.Tx组接触角为76.36°±4.65°, Tx-sal组接触角为71.26°±3.55°, Tx组接触角度数略高于Tx-sal组, 差异无显著统计学意义.Tx-sal组溶血率为1.5%, Tx组溶血率为2.1%.Tx组复钙化凝血时间为 (212±11.32) s, Tx-sal组复钙化凝血时间为 (231±13.53) s, Tx组与Tx-sal组的复钙化凝血时间差异有显著统计学意义.Tx-sal组相比Tx组延缓了凝血时间, 抗凝血性更加优良.Tx-sal组黏附的血小板数目低于Tx组的相应数目.Tx-sal组补体激活水平低.与传统的Triton-x100法制备的脱细胞血管支架相比, 加入丹参酚酸B后处理的脱细胞血管支架具有更加优良的血液相容性, 更适合作为组织工程材料应用于心脑血管疾病的治疗, 在临床医学上的应用前景更加广阔.

    • 摘要: In order to study the desorption characteristics of diesel from soils in the presence of Triton X-100 and the factors governing the desorption,the desorption of diesel from six soils including Zhejiang paddy soil,Chongqing purple soil,Jiangxi red earth,Hainan sandy soil,Qinghai gray desert soil and Heilongjiang black soil were investigated using batch equilibration technique and the factors governing the desorption were investigated. It was demonstrated that the desorption rate of diesel in Zhejiang paddy soil, Chongqing purple soil, Jiangxi red earth,Hainan sandy soil,Qinghai gray desert soil and Heilongjiang black soil were fast initially and then slowed down before reaching the desorption equilibrium. The equilibrium desorption capacity were 1.61, 1.85, 1.80, 2.29, 2.01 and 1.13 mg∕g, respectively. The desorption kinetics results can be satisfactorily described with the pseudo-second model (R2>0.99). The desorption isotherms of diesel in six soils were found reasonably fitted to the modified Michaelis-Menten equation (R2>0.92), and the maximum equilibrium desorption capacity (Qmax) ranged from 1.81 mg∕g to 2.23 mg∕g. The maximum equilibrium desorption efficiency (ρmax) of diesel from Zhejiang paddy soil,Chongqing purple soil,Jiangxi red earth, Hainan sandy soil, Qinghai gray desert soil and Heilongjiang black soil were 73.20%,78.06%,75.63%,90.36%,79.89% and 62.92%,respectively. The soil physiochemical properties on diesel desorption were influenced by many factors. The linear correlation analysis indicated that the ρmaxwas positively correlated with soil w(sand) (P0.99);6种典型土壤中柴油的等温解吸特征可较好地用修正的米氏方程模型进行描述(R2>0.92). Qmax(柴油最大解吸量)介于1.81~2.23 mg∕g之间,浙江水稻土、重庆紫壤、江西红壤、海南沙土、青海灰漠土和黑龙江黑土中ρmax(柴油最大解吸率)分别为73.20%、78.06%、75.63%、90.36%、79.89%和62.92%;土壤各理化性质对Triton X-100解吸土壤中柴油的影响起综合作用,其中土壤w(砂粒)与ρmax呈显著正相关(R2=0.9936,P<0.01),对Triton X-100解吸柴油的影响最大;而CEC(阳离子交换量)、w(OM)、w(黏粒)均与ρmax呈显著负相关(P<0.05).研究显示,修正的米氏方程可用于描述柴油在土壤-水-表面活性剂Triton X-100系统中的解吸行为,w(砂粒)是影响不同土壤中柴油解吸的关键因子,可为应用Triton X-100修复柴油污染土壤提供理论基础.

    • 摘要: 探讨表面活性剂TritonX-100对桦褐孔菌液体深层发酵产活性多糖的影响,利用醇沉法得到胞外多糖和胞内多糖,通过测定菌丝体量和胞内外多糖产量,明确TritonX-100对多糖的促进作用.进一步探讨TritonX-100的最佳添加时间及浓度,得出在第0d添加0.1%TritonX-100,促进效果最显著.多糖的DPPH自由基清除率测定结果表明,TritonX-100也促进桦褐孔菌多糖的抗氧化活性.通过对多糖化学成分以及单糖组成的分析,证明多糖中的糖、蛋白含量及单糖的组成与DPPH自由基清除率具有一定关联性.以上结果为进一步深入研究桦褐孔菌多糖奠定理论基础,从而建立一种桦褐孔菌发酵多糖的高产、高活性的液体深层发酵制备技术.%This study aims to discuss the effect of surfactant TritonX-100 on the production of active polysaccharides produced from Inonotus obliquus under submerged liquid fermentation.Extracellular polysaccharide(EPS) and intracellular polysaccharide (IPS1,IPS2) were obtained with the alcohol precipitation method,and the promoting effect of TritonX-100 on polysaccharide was determined by measuring the mycelium quantity and yield of extracellular and intracellular polysaccharides.The best time and concentration for adding TritonX-100 were further studied.It is found that the promoting effect is most significant by adding 0.1% TritonX-100 on Day 0.The measurement result of DPPH free radical clearance ratio of polysaccharide indicates that TritonX-100 also can promote the antioxidant activity of I.obliquus polysaccharide.The analysis of polysaccharide chemical components and monosaccharide composition indicates that the saccharide,protein content and monosaccharide composition of polysaccharide have certain relevance to DPPH free radical clearance ratio.The conclusions presented above lay a theoretical foundation for further study on inonotus obliquus polysaccharide,based on which a submerged liquid fermentation technology of inonotus obliquus polysaccharide of high yield and high activity can be developed.
