摘要:

文题释义:

异烟肼:对结核杆菌有抑制和杀灭作用,其生物膜穿透性好,由于疗效佳、毒性小、价廉、口服方便,故被列为首选抗结核药。该药品常需和其他抗结核病药联合应用,以增强疗效和克服耐药菌。

成骨细胞:主要由内外骨膜和骨髓基质内的间充质始祖细胞分化而来,能特异性分泌多种生物活性物质,调节并影响骨的形成和重建过程。

背景:异烟肼作为抗结核的一线药物,对细胞内外结核菌都具有极强的杀菌效果,但目前还没有研究报道异烟肼对成骨细胞的毒性作用。

目的:探讨不同质量浓度异烟肼对新生SD大鼠成骨细胞增殖、分化的影响。

方法:将不同质量浓度(0,10,20,30,40,50,60,100 mg/L)异烟肼分别加入新生SD大鼠第3代成骨细胞中,采用CCK-8法、碱性磷酸酶活性试剂盒和免疫荧光染色法检测异烟肼对成骨细胞增殖、分化的影响。

结果与结论:与对照组比较,异烟肼质量浓度在30 mg/L时,成骨细胞增殖开始受到抑制;随着异烟肼质量浓度增高,碱性磷酸酶活性、Ⅰ型胶原表达明显降低。结果表明,异烟肼质量浓度过高对成骨细胞增殖和分化具有抑制作用。

Abstract:

BACKGROUND: As a first-line antituberculosis drug, isoniazide exerts strong sterilization effect on the Tubercle bacillus inside and outside the cells. But the toxic effect of isoniazide on osteoblasts is never reported.

OBJECTIVE: To investigate the effect of different concentrations of isoniazide on the proliferation and differentiation of osteoblasts from newborn Sprague-Dawley rats.

METHODS: Isoniazide treatment at 0, 10, 20, 30, 40, 50, 60, and 100 mg/L was applied on passage 3 osteoblasts from newborn Sprague-Dawley rats. Then, osteoblast proliferation and differentiation was detected using cell counting kit-8 assay, alkaline phosphatase activity kit and immunohistochemical staining.

RESULTS AND CONCLUSION: Compared with the control group, the proliferation of osteoblasts was significantly inhibited when the isoniazide concentration was 30 mg/L. In addition, increasing isoniazide concentrations inhibited alkaline phosphatase activity and type I collagen expression. To conclude, isoniazide at exorbitant concentration exerts adverse effects on the proliferation and differentiation of osteoblasts.

Key words: isoniazid, osteoblasts, alkaline phosphatase, type I collagen, cell proliferation, cell differentiation
