Abstract:
Objective To study the effects of PNESF at different voltages on the life spans of ascites tumor bearing mice.Methods Forty ascites tumor bearing mice were divided into 5 groups and exposed to PNESF at 0,10,17,23 and 30 kV,respectively,for 30 minutes daily on 4 successive days.All of the animals then received routine care until death.Their eating habits,body weights and life spans were observed.A straight line fitting method was used for statistical analysis. Results The body weights of the mice exposed to 17 kV and 23 kV PNESF increased quickly during the four days of PNESF exposure.The weight gain in all groups declined after PNESF exposure was stopped.Thereafter the body weights of the mice exposed to the 17 kV PNESF increased more slowly than those in the control group.The mice exposed to the 23 kV PNESF gained weight more quickly than other groups.The mice exposed to the 17 kV PNESF lived the longest,demonstrating a lengthening of life of 25.5%compared with the control group.Conclusion Exposure to a PNESF of appropriate intensity might significantly increase the life span of ascites tumor bearing mice.
