Objective:
To examine the effect of different reduced caloric intake on mice transplanted with S180 ascitic tumor.
Methods:
The institute for cancer research (ICR) mice were randomly divided into control group, 3.0 standard feed (SF) group, 2.0 SF group and 1.3 SF group. The mice in control group were fed enough (about 5 g/d) dietary intake, while the amounts of dietary intake in the latter three groups were scaled down in the proportion of 65%, which were 3.0 g, 2.0 g and 1.3 g standard feed respectively. Meanwhile the essential vitamins were added to the latter three groups to keep the amount of intake the same as that of the control's.
Results:
For most of the mice, the caloric intake obviously prolonged the mean survival days and improved the life quality was 7.14 kcal/d, and the fasting blood glucose level was 2-3 mmol/L.
Conclusion:
Properly reduced caloric intake and keeping lower blood glucose level is beneficial to prolonging the survival time of mice transplanted with S180 ascitic cancer.
