摘    要:目的研究毛果芸香碱对体外培养兔泪腺上皮细胞蛋白分泌与合成的影响。设计实验研究。研究对象培养的兔泪腺上皮细胞。方法对培养细胞进行广谱细胞角蛋白、波形蛋白免疫组化染色及电镜观察鉴定后,培养的兔泪腺上皮细胞中,分别加入700、70、7、0.7和0.07μmol/L的毛果芸香碱,培养24小时,分别测定培养液和细胞中的β-氨基已糖苷酶活性。在不同浓度毛果芸香碱的培养细胞中加入70μmol/L阿托品,培养24小时,分别测定培养液和细胞中的β-氨基已糖苷酶活性。主要指标β-氨基已糖苷酶活胜(光密度值,OD)。结果毛果芸香碱在700、70、7、0.7和0.07μmol/L浓度时使泪腺上皮细胞培养液β-氨基已糖苷酶活性OD值分别增加17.7%(P=0.015)、14.7%(P=0.038)、5.7%(P=0.399)、413%(P=0.517)和2.0%(P=0.7641,使泪腺上皮细胞冻融液β-氨基已糖苷酶活性OD值分别增加25.0%(P=0.000)、16.8%(P=0.001)、10.6%(P=0.023)、7.6%(P=0.089)和4.8%(P=0.271)。阿托品抑制毛果芸香碱的作用,使泪腺上皮细胞培养液β-氨基已糖苷酶活性OD值分别减少20.5%(P=0.018)、15.1%(P=0.029)、10.1%(P=0.097)、11.5%(P=0.118)和7.9%(P=0.085),使泪腺上皮细胞冻融液B一氨基已糖苷酶活性OD值分别减少10.0%(P=0.039)、4.8%(P=0.113)、6.2%(P=0.162)、2.9%(P=0.315)和0%(P=0.300)。结论毛果芸香碱可增加培养的泪腺上皮细胞的蛋白分泌和合成,阿托品可抑制毛果芸香碱的作用。

Abstract:Objective To study the secretion and synthesis of lacrimal epithelial cells by pilocarpine in vitro. Design Experimental study. Participants Cultured rabbit lacrimal epithelial cells. Methods After identifying cultured cells by immunohistochemistry of broad-spectrum cytokeratin, vimentin and observation by electron microscope, rabbit lacrimal epithelial ceils were added 700, 70, 7, 0.7 and 0.07 μmol/L pilocarpine and cultured for 24 hours. The β-hexosaminidase activity was detected in medium and cells. Rabbit lacrimal epithelial cells were added 70 μmol/L atropine and different concentration pilocarpine,then cultured for 24 hours. The β-hex- osaminidase activity was detected in medium and cells. Main Outcome Measures β-hexosaminidase activity (OD value). Results Pilocarpine increased the β-hexosaminidase activity OD value by 17.7% (P=0.015), 14.7%(P=0.038), 5.7%(P=0.399), 4.3%(P=0.517) and 2.0% (P=0.764) in lacrimal epithelial cells medium, by 25.0% (P=0.000), 16.8%(P=0.001), 10.6%(P=0.023), 7.6%(P=0.089) and 4.8% (P=0.271) in lacrimal epithelial cell freeze-thaw liquid with 700, 70, 7, 0.7 and 0.07 μmol/L. Atropine inhibited the effects of pilocarpine by 20.5%(P=0.018), 15.1%(P=0.029), 10.1%(P=0.097), 11.5%(P=0.118) and 7.9%(P=0.085) in lacrimal epithelial cells medium, by 10.0%(P=0.039), 4.8%(P=0.113), 6.2%(P=0.162), 2.9%(P=0.315) and 0%(P=0.300) in lacrimal epithelial cell freeze-thaw liquid. Conclusions Pilocarpine can increase the protein secretion and synthesis in cultured lacrimal epithelial ceils. Atropine can inhibit the effects of pilocarpine.
Keywords:lacrimal epithelial cells  culture  pilocarpine  atropine  protein secretion and synthesis
