基于粒子设计原理的青黛-白矾复合粒子的制备及表征

目的 基于粒子设计原理,制备并表征具有核壳结构的青黛-白矾复合粒子。方法 以粒径为评价指标,研究壳粒子的制备时间;以接触角为评价指标,研究复合粒子的复合时间。分别制备青黛细粉、白矾细粉、青黛-白矾细粉混合物及青黛-白矾复合粒子,从粒径分布、粉末颜色、微观结构、表面元素分布及晶型结构方面对比研究4种粉末的差异,以表征复合粒子的核壳结构。结果 壳粒子在振动磨中粉碎17 min后加入核粒子,两者一起复合5 min,复合粒子的表面润湿性与壳粒子无显著差异。4种粉末在粒径分布、颜色、微观结构、表面元素分布及晶型结构上存在显著差异;复合粒子的众位粒径d_0.9为32.818 μm,远小于混合物,其颜色、表面元素分布与壳粒子高度类似,扫描电镜（SEM）观察到存在众多小颗粒包覆在大颗粒表面的微观结构,X射线衍射谱中核粒子大部分的特征峰消失或强度减弱。结论 成功制备出了具有核壳结构的青黛-白矾复合粒子,其表面性质与壳粒子类似,与核粒子明显不同。     

青黛饮片亲水性改性工艺的优选研究

目的通过筛选增强青黛亲水性的改性剂来研究改性剂与青黛作用方式,并优选出最佳改性工艺,制备适宜汤剂给药的新型饮片,满足临床用药需求。方法以接触角为亲水改性效果评价指标,通过筛选出不同醇类试剂中最优的改性剂,再经过不同的干燥温度对改性青黛进行热稳定性考察,结合不同醇类试剂、靛蓝、靛玉红的微观结构来初步探讨改性剂与青黛改性作用机制以及改性效果的热稳定性。通过单因素试验考察探讨接触角与改善青黛亲水性的关系,并采用均匀设计初步确定最佳工艺。结果不同醇类试剂相较于普通青黛都有改性效果,改性过程中醇分子的-CH3和-OH贡献不同,一元醇碳链越长改性效果越好,多元醇-OH越多改性效果越好,但从试剂的适用性及安全性考虑最佳改性剂为乙醇,最优改性工艺:改性剂用量为19%的乙醇、研磨23 min。结论醇类能有效改善青黛的润湿问题,使用乙醇作为改性剂可行性好,改性工艺稳定可靠,可以成功制备出青黛饮片。     

基于UPLC-Q-TOF-MS/MS技术分析不同配伍比例雄黄对青黛入血成分的影响

目的:基于青黄散的配伍组方,探讨不同比例雄黄与青黛配伍后青黛在大鼠血清中移行成分的差异。方法:采用UPLC-Q-TOF-MS/MS技术对青黛供试品溶液、空白血清以及3种不同配比(青黛10 g分别配伍雄黄52. 5,105,210 mg,依次记为A组,B组,C组)青黄散含药血清进行检测,结合青黛供试品溶液中鉴定的化学成分,分析3组复方中青黛在大鼠体内的移行成分差异;以3组青黄散含药血清作用于人白血病细胞HL-60细胞,采用细胞计数试剂盒-8(CCK-8)法检测各含药血清对HL-60细胞活性的影响。结果:从青黄散A组,B组,C组含药血清中分别检测到了19,22,25个移行成分,且3组含药血清均含有来自青黛供试品溶液中的5个原型成分,分别为色胺酮,靛蓝,靛玉红,2-氨基苯甲酸和N-苯基-2-萘胺;CCK-8法检测结果表明青黄散C组含药血清对HL-60细胞的抑制作用最强。结论:固定青黛剂量后,随着雄黄剂量的增加,含药血清中移行成分增多,且对HL-60细胞的抑制作用也逐渐增强,提示雄黄可能会促进青黛中有效成分在体内的吸收,从而增强药效,进一步阐释了不同比例雄黄和青黛的配伍规律及药效物质基础。     

双波长分光光度法测定靛玉红片中靛玉红的含量

靛玉红是中药青黛中治疗慢性粒细胞白血病的有效成分,目前常用半合成品。靛玉红片中靛玉红含量的测定方法有多种,其中比色法操作较繁,不能消除靛蓝的干扰。解联立方程法必须已知或用实验测定。双波长薄层扫描法操作不够迅速。后两种方法回收率均偏低。本文报道的方法简便,测定迅速,准确度较高。

Life-threatening reaction to indigo carmine – A sulfa allergy?

Adhesion-promoting properties of dyes routinely used during fertility surgeries

Purpose With the link between peritoneal adhesions and infertility well established, it is critical that materials used in pelvic surgery be tested for their adhesionforming properties. The current study examined the adhesion-inducing properties of two dyes routinely used for visualization during pelvic surgery.Design In vivoand in vitroexamination of the effects of the dyes methylene blue and indigo carmine on adhesion formation in a mouse model.Method A series of three experiments was conducted. In the first, dyes were injected directly into the peritoneal cavity. The mice were then sacrificed at one of two time points and the peritoneal cavity examined for adhesion formation. In addition, because of their purposed role in adhesion formation, macrophages from the cavity were examined for signs of dye-induced activation. Further studies of macrophage activation were then conducted in vitroto determine the effects of dye concentration and exposure time on the activation process.Results Both methylene blue and indigo carmine appeared to induce adhesion formation as well as macrophage activation in vivo.Further, long-term exposure to visual concentrations of both dyes appeared to induce macrophage activation. However, only those macrophages exposed to methylene blue exhibited signs of activation when the exposure time was limited to times equivalent to those which might be expected during surgery.Conclusion Of the two dyes tested, indigo carmine might be the dye of choice in surgeries where fertility is to be maintained.Presented in part as the 1993 Pritchard Prize Paper at the sixty-Fourth Annual Meeting of the Texas Association of Obstetricians and Gynecologists and the Texas Section of ACOG, Austin, TX, March 10–12, 1993, and at the 50th Annual Meeting of the American Fertility Society, San Antonio, Texas, November 5–10, 1994.
