文题释义:
三七总皂苷:中成药名。由三七总皂苷(其主要成分为人参皂苷Rb1、人参皂苷Rg1、三七皂苷R1)组成。具有活血祛瘀、通脉活络、抑制血小板聚集和增加脑血流量的作用,用于脑血管后遗症、视网膜中央静脉阻塞、眼前房出血等。
细胞器:是细胞质中具有特定形态结构和功能的微器官,也称为拟器官或亚结构。其中质体与液泡在光镜下即可分辨,其他细胞器一般需借助电子显微镜方可观察。细胞中的细胞器主要有线粒体、内质网、中心体、叶绿体,高尔基体、核糖体等,它们组成了细胞的基本结构,使细胞能正常的工作,运转。
摘要
背景
:前期研究证实三七总皂苷对早期兔酒精性股骨头缺血性坏死骨细胞超微结构形态的修复可以起到良好的促进作用。
目的:透射电镜观察三七总皂苷干预兔激素性股骨头缺血坏死骨细胞形态结构变化。
方法:9-10周龄健康雄性新西兰兔90只,体质量3.5-4.0 kg,由广西中医药大学实验中心提供。采用改良马血清联合甲泼尼龙琥珀酸钠造模方法建立兔激素性股骨头缺血性坏死模型。实验过程死亡15只,余75只分为生理盐水组、鹿瓜多肽组、三七总皂苷组各25只,分别生理盐水、鹿瓜多肽、三七总皂苷干预治疗5周,透射电镜观察各组骨细胞结构变化。
结果与结论:①生理盐水组兔股骨头骨细胞成熟减少,血管内皮细胞受损,线粒体肿胀,嵴结构模糊,核碎裂,脂滴出现;②三七总皂苷组、鹿瓜多肽组兔股骨头骨细胞成熟,血管内皮细胞损伤少,肿胀线粒体减轻,结构清晰,肥大脂肪细胞及脂滴减少;③三七总皂苷组和鹿瓜多肽组骨细胞形态结构变化优于生理盐水组(P < 0.05);④结果说明,三七总皂苷干预兔激素性股骨头缺血性坏死,对骨细胞形态结构有修复作用。

Abstract:

BACKGROUND: Preliminary studies have shown that panax notoginseng saponins can promote the repair of osteocyte ultrastructure in a rabbit with alcohol-induced osteonecrosis of the femoral head. 
OBJECTIVE: To observe the structural changes of osteocytes in a rabbit with steroid-induced osteonecrosis of the femoral head treated with panax notoginseng saponins by transmission electron microscope.
METHODS: Ninety 9-10 weeks old healthy male New Zealand rabbits (provided by Laboratory Center of Guangxi University of Chinese Medicine), weighting 3.5-4.0 kg were selected. Rabbit models of steroid-induced osteonecrosis of the femoral head were established by injecting modified horse serum combined with methylprednisolone sodium succinate. Fifteen rabbits died, so the remaining 75 rabbits were divided into three groups (n=25 per group), and then treated with normal saline, cervus and cucumis polypeptide or panax notoginseng saponins, respectively for 5 weeks. The structural changes of osteocytes were observed under transmission electron microscope.
RESULTS AND CONCLUSION: In the normal saline group, the number of mature osteocytes was reduced, vascular endothelial cells were damaged, and mitochondria swelling, fuzzy cristae structure, nuclear fragmentation, and lipid droplets were observed. In the cervus and cucumis polypeptide and panax notoginseng saponins groups, there were more mature osteocytes and less vascular endothelial cell damage, swollen mitochondria alleviated with clear structure, and the numbers of mast adocytes and lipid droplets were decreased. The structural changes of osteocytes in the cervus and cucumis polypeptide and panax notoginseng saponins groups were significantly more encouraging than those in the normal saline group (P < 0.05). Our results indicate that show that, panax notoginseng saponins can repair the osteocyte structure of rabbits with steroid-induced osteonecrosis of the femoral head.
