目的 探讨晕可宁颗粒的主要药效学 ,为临床提供药效学资料及治疗学基础。方法 采用三氯甲烷破坏豚鼠一侧膜迷路感受器模型 ,探讨受试药对眼震颤、摆头及旋转的影响 ;采用内淋巴囊和内淋巴管阻塞手术复制豚鼠膜迷路实验性膜迷路积水模型 ,研究内耳组织平均中阶面积 (SMA)增加率及形态学的变化。结果 抑眩宁阳性对照组、晕可宁颗粒 (8、16g/kg)模型给药组豚鼠眼球震颤次数减少 ,差异有显著意义 (P <0 .0 5 )。成功复制了不同程度膜迷路积水豚鼠模型 ,表现为前庭膜重度膨出 ,前庭阶缩小 ,膜蜗管增大 ,SMA增加率变大 ,差异有显著意义 (P <0 .0 1) ;晕可宁颗粒灌胃后可减轻豚鼠实验性膜迷路积水的程度 ,差异有显著意义 (P <0 .0 1) ;但与空白对照组比较SMA增加率差异无显著意义 (P >0 .0 5 )。结论 晕可宁颗粒可以减轻内淋巴囊积水程度 ,对梅尼埃病症状有对抗治疗作用。 相似文献

Our study justified by the frequency of acute appendicitis and the possibility of anatomic variations of the caecoappendicular area attempt to index the topographic variations of the vermiform appendix (v.a.). On 80 fresh native cadavers (62 men and 18 women) without surgical antecedent whose mean age was 36 years (range between 16 and 78 years) we note the morphotype and the height. More over we study the intraperitoneal projection of the Mac Burney point, topography and shape of the cecum and the situation, shape and dimensions of the v.a. We note also the level of implantation of this latter on the cecum, appearance of the mesoappendix and the distance separating the base of the appendix to the ileo-caecal junction. Mac Burney's point permitted to localize appendix in 66%; the cecum has more often than not the form of a bulb (98.7%) and sited in right fossa iliaca. We noted 7 types of topographic disposition; front varieties were more frequent (68.7%) notably the pelvic direction (51.2%) with a medial (72.5%) or a posteromedial (27.5%) establishment on the cecum. The v.a. was more often in the form of worm with a long mesoappendix; his mean length was 106.4 mm (between 65 and 160 mm) and the mean diameter 6.77 mm (range between 4 and 10 mm). The distance which separated the base of the appendix to the ileo-cecal junction varied between 15 to 40 mm with a mean distance of 24.2 mm. Thus in this study, dimensions of the v.a. were very variables. Located in right fossa iliaca he adopted a front topography with pelvic direction and medial establishment on bulbar cecum. In spite of scarcity of ectopic situation of the appendix for which laparoscopic approach is salutary, a similar topographic study during surgical treatment of acute appendicitis will be interesting. 相似文献

We describe three cases of intravascular lymphoma B with different clinical presentation: one case of a cutaneous variant and two cases with surrenal and cutaneous localisation. All patients are in complete remission after chemotherapy alone or after chemotherapy and autologous stem cells transplantation. The review of the literature as well as our cases specify the interest of an aggressive chemotherapy with autologous of peripheral stem cells if it was possible. 相似文献
