香椿皮与臭椿皮的体外抗菌作用比较

目的：观察香椿皮、臭椿皮的抗菌作用。方法：本文采用琼脂平板稀释法对香椿皮、臭椿皮的水提取物和醇提取物进行了体外抗菌试验对比研究。结果：香棒皮的水提取物对金黄色葡萄球菌、绿脓杆菌、大肠杆菌均有抑杀作用;而臭椿皮水提聚物对金黄色葡萄球菌只有微弱的抑杀作用。对绿脓杆菌、大肠杆菌无抑杀作用。结论：香椿皮、臭椿皮来源于两种不同科属的植物,抗菌效果不同,成分不同,不宜混用。     

炎痛喜康栓剂的家兔体内生物利用度及其体外溶出速度

给7只家兔使用两种炎痛喜康栓剂和一种片剂,用HPLC法研究这两种剂型的相对生物利用度。结果显示:栓剂的药-时曲线下面积(AUC)与片剂没有显著差异,位C_m较片剂高。体内吸收％与体外溶出％有良好的相关性。     

Polymorphonuclear motility: measurement by computer-linked image analysis

Most methods of measuring neutrophil motility provide information mainly about the performance of a small proportion of the fastest moving cells. Application of a computer-linked image analysis technique, using the "Quantimet," provides a convenient, automated method of measuring the motility of the whole cell population. This makes it possible to test whether changes in motility represent a homogeneous alteration affecting all cells or a change in the numbers or performance of a subset of cells. In this study the neutrophils from patients with uncomplicated rheumatoid arthritis were found to perform similarly to normals, while cells from patients with Felty's syndrome were markedly slower. This was an overall, homogeneous slowing of the whole cell population, not due to a loss of fast moving cells.
