乳糜微粒流对黄芩苷纳米乳动物体内组织分布的影响研究

目的 探究乳糜微粒流对黄芩苷纳米乳大鼠体内淋巴组织的分布,初步阐明黄芩苷纳米乳具有淋巴靶向性的机制.方法 利用高效液相色谱法测定生物样品中黄芩苷浓度;大鼠分别灌胃给予黄芩苷纳米乳和黄芩苷混悬液,剂量为144.0 mg/kg;建立大鼠乳糜微粒流阻断模型,考察乳糜微粒介导的跨膜转运对黄芩苷纳米乳在淋巴组织器官分布的影响.结果 与未阻断组相比,大鼠体内乳糜微粒流的阻断,可影响黄芩苷纳米乳组大鼠体内脾、胸腺和淋巴结血药浓度-时间曲线下面积、药峰浓度等参数,但未对黄芩苷混悬剂组大鼠的体内药物代谢动力学参数产生影响.结论 黄芩苷纳米乳刺激乳糜微粒的分泌,增加药物经淋巴途径的转运量,药物富集于淋巴器官,可能是黄芩苷纳米乳靶向淋巴器官的主要机制.     

电针足三里对应激性胃粘膜损伤的保护作用

目的；研究电针足三里穴对大鼠应激性胃粘膜损伤的保护作用。方法；将１８只大鼠随机分为３组，即正常对照组，模型组，电针组，采用束缚－冷应激胃粘膜损伤模型，观察电针足三里穴后胃粘膜损伤情况，以及胃粘膜血流量，血浆中肿瘤坏死因子，前列环素／血栓素含量变化。结果：电针后，胃粘膜电流量增加，肿瘤坏死因子和血栓素含量下降，前列环素含量增加。结论：电针足三里穴对胃粘膜损伤有保护作用，肿瘤坏死因子在其中是重要介质。     

毫米波照射肾俞穴对家兔肾血流量的影响

In this Paper, the low Power milimeter wave ( MMW ) was employed to irradiate the rabbit on "Shenshu" point and on the surface of kidney, and the renal blood flow ( RBF ) before and after irradiation were measured by means of hydragon gas clearance method. The results show that RBF of both normal rabbit and that with acute renal blood deficiency are significantly increased after irradiating "Shenshu" Point (P<0.05); and compared with the rabbit whose kidney surface was irradiated, the RBF before and after irradiation have no significant difference (P>0.05); and that the RBF is increased more in the rabbit whose renal nerve was excised than in rabbit whose renal nerve was intact; there is a significant difference between them (P<0.05). The results of this paper suggest the effect of MMW irradiating "Shenshu" Point be similar to that of MMW irradiating the kidney surface, and as a new invulnarable specific therapy on points, MMW have a latent value in clinics.
