本文证明培育牛黄对乙酰胆硷与氯化钡所引起的小白鼠离体小肠痉挛有解痉作用。培育牛黄的成份中去氧胆酸具有较强的抗乙酰胆硷与氯化钡作用,其浓度与效应呈直线相关。其成分中的胆酸仅有较弱的抗乙酰胆硷作用,且浓度与效应不呈直线相关,也无抗氯化钡作用。 相似文献

线性规化是运筹学和系统工程中常用的数学方法，将物理学直接应用于后两门学科中去解决问题并不很普遍。本文就一个属于线规划的问题，为什么能用一个简单的力学模型来求解进行了探讨。结果表明物理学的规律有可能在求解数学问题中发挥作用。 相似文献

对70头山羊、50头绵羊和5头奶山羊进行了人工培植羊黄研究。在植黄后一年,对42头山羊,10头绵羊和1头奶山羊取黄,在羊的胆囊内形成了羊黄。对11个羊黄样品进行了胆色素、总胆固醇和总胆酸等项目测定,结果表明与天然牛黄主要成分相同,但含量有所不同。对5个羊黄样品进行了超微结构观察,结果与天然牛黄一致。 对人工培植羊黄羊的胆囊胆汁进行了测定,β-葡萄糖醛酸苷酶活性(以下简称β-G酶活性)和粘蛋白含量明显升高。因接种的大肠杆菌血清型不同,β-G酶活性也呈现不同程度的变化。对培植羊黄羊的胆囊进行了组织学检查,胆囊壁粘膜上皮柱细胞间的杯状细胞及固有膜中的粘液腺大量增生,是胆汁中多糖粘蛋白增高的组织学基础。 对培植羊黄进行了药理学试验,其结果与天然牛黄完全一样。 相似文献

A novel Bacillus species of Calculus Bovis (cow gallstone) was isolated and identified in this study. Morphological features, bacterial fatty acid analysis using a microbial identification system, carbon source utilization profiles using Biolog system and 16S rDNA sequencing were employed to identify the isolated bacterium. This isolated bacterium was observed to be Gram‐negative, aerobic growing, rod‐shaped and short chain. The results of bacterial fatty acid analysis and physiological characteristics were not matched to the database. The main fatty acids found in the bacterium were 65.96% branched chain saturated fatty acids (iso C11:0, anteiso C11:0 and iso C13:0～anteiso C19:0). The bacterium oxidized 35 carbon sources and weakly responded with 49 of the 95 different carbon sources analyzed with the Biolog identification system. Based on 16S rDNA sequence analysis, this bacterium was classified as a novel Bacillus species. 相似文献

犬尿石症是临床上常见的一种泌尿系统疾病,指在犬矿物质代谢紊乱情况下,尿液中析出的盐类结晶以脱落的上皮细胞等异物为核心逐渐形成的矿物质凝结物,积滞于尿路并刺激尿路黏膜引起出血、炎症和阻塞的一种泌尿系统疾病。笔者就犬尿结石症的结石成因、分类、治疗、预防等方面进行了综述。 相似文献

The purpose of the study was to investigate bioactive compounds of in vitro cultured Calculus Suis and natural Calculus Bovis obtained as valuable by‐products from animals used for meat production. The results showed that the components of natural Calculus Bovis were rich in bilirubin and biliverdin and had higher content of essential amino acids. The major amino acids of in vitro cultured Calculus Suis were identified as glycine, alanine, glutamic acid and aspartic acid, and those for natural Calculus Bovis were found to be glutamic acid, aspartic acid, proline, and arginine. The methionine and cysteine contents of precursors for glutathione in natural Calculus Bovis were significantly higher than those of in vitro cultured Calculus Suis. The mineral contents of zinc, iron and manganese of natural Calculus Bovis were significantly higher than those of in vitro cultured Calculus Suis. The major bile acids in both products were cholic acid and dehydrocholic acid, respectively. The chenodeoxycholic and ursodeoxycholic acid content of in vitro cultured Calculus Suis was significantly higher than that of natural Calculus Bovis. 相似文献
