- Objective. To assess the effects of reloading after simulated microgravity on PG metabolism in nucleus pulposus (NP) and anulus fibrosus (AF). 目的:評測模擬微重力產生的繼發負荷對纖維環和髓核中的粘蛋白的變化的影響。
- Conclusion.A needle puncture may directly alter mechanical properties via nucleus pulposus depressurization and/or anulus fibrosus damage, depending on the relative needle size. 結論:針頭大小的比較得知,針頭穿刺通過髓核減壓和(或)纖維環損傷,直接改變了椎間盤力學效能。
- Results.Positive staining of collagen IX was detected in both anulus fibrosus and nucleus pulposus sections confirming its presence in the scoliosis discs. 結果:通過染色的膠原質IX在纖維環和髓核中的發現從而確定了它在脊柱側凸病人中的存在。
- Anulus fibrosus and nucleus pulposus from a set of the scoliosis discs were used to perform immunohistochemistry to demonstrate the presence of collagen IX in the scoliosis discs. 來自一組脊柱側凸的纖維環和髓核被用來進行免疫組織化學實驗從而證實膠原質IX在脊柱側凸病人椎間盤中的存在。
- Methods.Cells of the nucleus pulposus and inner and outer anulus fibrosus were enzymatically isolated from boine coccygeal tissue and precultured in alginate beads for 14 days. 方法:髓核細胞和內外纖維環通過酶與牛尾骨組織隔絕並在14天前培養於藻酸鹽中。
- Degeneration of the anulus fibrosus after the replacement treatment was delayed by presering disc height and occupying the space of the nucleus pulposus. 通過維持椎間盤高度與侵佔髓核空間的方式,置換處理后的纖維環退化被延遲了。
- The application of pulsed low intensity ultrasound increased proteoglycan content in alginate beads containing inner and outer anulus fibrosus cells (P <0.05). 給予低強度的脈衝超聲增加了含有內外纖維環細胞的藻酸鹽中的膠原含量(P<0.;05)。
- In all the discs, including nonpunctured control discs, protein gene product 9.5-immunoreactie fibers were only occasionally obsered in the outermost part of the anulus fibrosus. 在包括未穿刺的對造組在內的所有椎間盤中,9.;5蛋白基因產物的免疫反應纖維只是偶爾在環狀纖維的最外邊被觀察到。
- Angiogenesis,osteophyte and cellular infiltration were not seen in the inner or middle layers of the anulus fibrosus or in the nucleus pulposus in any section of any group. 在整個實驗過程中,各組椎間盤髓核和中、內層纖維環中均未觀察到血管增生、炎性細胞浸潤及骨贅形成。
- The application of pulsed low intensity ultrasound increased proteoglycan content in alginate beads containing inner and outer anulus fibrosus cells (P < 0.05). 給予低強度的脈衝超聲增加了含有內外纖維環細胞的藻酸鹽中的膠原含量(P<0.;05)。
- On day 20, proteoglycan synthesis was increased by the application of pulsed low intensity ultrasound in nucleus pulposus and inner and outer anulus fibrosus cells (24%-26% increase, P <0.001). 20天時,超聲刺激組在髓核和內外纖維環細胞中有蛋白多糖的合成的增加(增高24%25-26%25;P<0.;001)。
- On day 20, proteoglycan synthesis was increased by the application of pulsed low intensity ultrasound in nucleus pulposus and inner and outer anulus fibrosus cells (24%-26% increase, P < 0.001). 20天時,超聲刺激組在髓核和內外纖維環細胞中有蛋白多糖的合成的增加(增高24%25-26%25;P<0.;001)。
