The methods on observation of the pattern of polyphase liposome and on determination of size and distribution of particles and particulate matter of intravenous injection of polyphase liposome (139) in the form of suspension are presented in this paper. Microscopic photographs of the injection of polyphase liposome (139) demonstrated the structure of artificial cell of polyphase liposome. With Coulter counter (TAⅡ) and microscope-micrometer the size and distribution of particles in the injection of polyphase liposome (139) in the form of suspension is shown. The results of measurement by the two methods are the same, especially the results on size of the large particles in the injection (139). Moreover, the membrane filter-microscope method described in USP ⅩⅩ for measureing the particulate matter in large-volume injection for single dose infusion was improved. The improved method was used in the determination of particulate matter in the intravenous injection of polyphase liposome (139) in the form of suspension. This method is not only more accurate but also more simple and convenient than the original USP ⅩⅩ method. 相似文献

目的测定地红霉素肠溶微丸的有关物质。方法采用HPLC法,色谱柱为DiamonsilTMC18(4.6mm×250mm,5μm);流动相为乙腈-磷酸盐缓冲液(取磷酸二氢钾1.41g,磷酸氢二钾6.91g,加水至1000ml)-甲醇(44:37:19);柱温40%;检测波长为205nm,流速2.0ml/min。结果此色谱条件下,药物与降解产物能达有效分离,地红霉素16R异构体与地红霉素16S异构体的分离度不小于2.0;地红霉素16R异构体与9S红霉胺的分离度不小于5.0。结论本法简便、准确,具有可行性。 相似文献

本文测定了磷酸淀粉(交联淀粉)的松密度、流动性、吸湿性,并与玉米淀粉、低取代羟丙基纤维素及羧甲基淀粉进行比较。结果交联淀粉的松密度和流动性最大,吸湿性与玉米淀粉相近。交联淀粉能促进磺胺嘧啶、阿司匹林,扑热息痛片剂的崩解和溶出,但作用一般不如羧甲基淀粉,有时接近于低取代羟丙基纤维素。 相似文献
