| 摘 要： | 本文旨在应用数字图象处理技术研究丁酸对人肺巨细胞癌PLA-801D细胞株胞核超微结构的影响。癌细胞在含2 mmol丁酸的条件下培养4天后,同对照组相比,胞核的周长无明显变化,但胞核面积比对照组者约大1.4倍,说明丁酸处理后癌细胞核外形趋向规则。实验组胞核的光密度比对照组者明显降低(后者比前者大2.7倍),表明丁酸作用后胞核中的染色质颗粒减少。结果提示丁酸可能具有促使恶性细胞胞核的某些恶性表型逆转化的生物学效应。

| Abstract: | The effects of butyric acid (BA) on nuclear ultrastructure of human lung giant cell carcinoma (Strain PLA-801 D) were studied with the digital image processing.It was found that the length of the nuclear circumference of the tumor cells incubated with 2mmol BA for 4 days was approximately equal to that of the control, whereas the nuclear area increased 1.4 times. It suggested that the nuclear profile tended to decome more regular. In addition, the nuclear optical density in the experimental group decreaed significantly compring with that of the control. This finding indicated that the chromatin granules within the nuclei were decreased by virtue of BA.BA may have a biological effect of reverse-transformation on the malignant cells. |
