Abstract:
OBJECTIVE：To study the anti-tumor effect of artemether （ARM）self-microemulsifying drug delivery system （SMEDDS） on human glioma subcutaneously transplanted model mice. METHODS ：Human glioma cell line SHG 44 was inoculated and passed on to establish subcutaneous transplanted tumor model of nude mice. At the 5th，10th，15th，20th and 25th day after inoculation ，the tumor tissue volume was measured and the growth curve was drawn to confirm the initial stage of rapid tumor proliferation. Thirty nude mice was collected to establish subeutaneously transplanted tumor nude model ，and then divided into control group （normal saline ），ARM suspension group [ 60 mg/（kg·d）]，ARM-SMEDDS low-dose ，medium-dose and high-dose groups [ 10，20，30 mg/（kg·d）] at the initial stage of rapid tumor proliferation. They were given normal saline and relevant solution intragastrically once a day ，for consecutive 30 d. The weight change and general sibuation of mice were recorded. The change of tumor volume was determined and relative tumor proliferation rate was calculated. RESULTS ：The subcutaneously transplanted tumor tissue entered the initial stage of rapid tumor proliferation from the 10th day after transplantation. The general situation was normal ，and there was no obvious abnormal reaction in mice of each group during treatment. Since 10th day of administration，tumor tissue volume of mice in ARM-SMEDDS groups were shortened significantly than control group （P＜0.05）. At 15th day of administration ，tumor volume of mice in ARM-SMEDDS groups were shortened significantly than ARM suspension group（P＜0.05）. After last administration ，relative tumor proliferation rates of mice in ARM-SMEDDS groups were decreased significantly，compared with ARM suspension group （P＜0.05）. CONCLUSIONS ：ARM-SMEDDS show significant inhibitory effect on the proliferation of human glioma ，and are better than suspension with higher dosage.
