一次性筷子、牙签及纸杯浸提液对小鼠L-929细胞的毒性作用
Toxic effects of the extracted solution of disposable chopstick toothpick or cup in murine L-929 cells
摘要
Abstract
OBJECTIVE: To evaluate the toxic effects of the extracted solution of disposable chopstick, toothpick or cup in murine L-929 cells. METHODS: According to the national standards, we prepared cell culture medium with the extracted solution of disposable chopsticks, toothpicks or cups. The cell morphology of murine L-929 cells was examined microscopically and cell viability was detected with WST-1 staining method. The detached cell ratios and the relative growth rate of L-929 cells were calculated. RESULTS: Compared with the control, after treatment for 4 days or 7 days, cells in the experimental groups showed signs of apoptosis or necrosis. The detached cell ratios were increased significantly(P＜0.05), while cell viability and relative growth rate declined significantly(P＜0.05).CONCLUSION: Treatments with extracted solution of disposable chopstick, toothpick or cup could affect cell growth and proliferation, thus probably possess potential toxic effects.关键词
