METHODS: 15 g/L silk fibroin solution was made by degumming, salvation and dialysis. Chitosan was dissolved in 2% acetic acid solution to prepare 25 g/L chitosan-acetic acid solution. Two solutions were mixed to prepare six silk fibroin/chitosan solutions, and mass ratio was 10: 0, 5: 5, 4: 6, 3: 7, 2: 8, 0: 10. These solutions were separately sucked in a 24-well plate. Following exhausting gas vacuole at 4 ℃, precooling was performed at -20 ℃ for 12 hours, followed by cryodesiccate for 30 hours.

通过脱胶、溶解、透析这3个主要步骤制成质量浓度为15 g/L的丝素溶液,将壳聚糖溶解在2%的醋酸溶液中制成25 g/L的壳聚糖-乙酸溶液,然后将两者混合,配制成丝素/壳聚糖质量比分别为10∶0,5∶5,4∶6,3∶7,2∶8,0∶10的6种溶液,分别吸入24孔板中,4 ℃排出气泡后,-20 ℃预冷冻12 h,再冷冻干燥30 h。

True phimosis causing urinary obstruction has been described (Campbell, l948), but must be exceedingly rare: in the cases I have seen in which this diagnosis has been made, simple separation of the prepuce has shown that there was no constriction of the preputial tributable to operation rather than to any pathological orifice.

尿的引起的真实的 phimosis 阻塞被描述了(坎贝尔,l948),但是必须极其稀罕:在情况中我看了在它这诊断被做了,包皮的简单的分离显示出了没有 preputial 的收缩到操作而非到任何 pathological 的 tributable 孔。

Methods:(1) Silica column chromatography and LH-20 were used in phytochemistry study.(2) Based on the extraction ratio of arctiin, the best extraction procedure was acheived under the direction of L9(34) orthogonal experimental design. From 10 types of resins, the one with the maximal binding ability for Arctii was selected and silica-column choramatograpy was used in its seperation and purification procedure.(3) The animal diabetic experimental model in Wistar rats was established with streptozotocin and many biochemical factors were used to indicate the pharmacological effects of arctiin, including glycosylated hemoglobin, serum creatinine, seralbumin, monoxide nitrogen, glycerin trilaurate, cholesterol, HDL-ch, LDL-ch, Blood urea nitrogen, creatinine, SOD, ET, MDA, total Urine protein and albuminuria.
