Antitumor effects of losartan in EAC mice

AIM: To study the antitumor e ff ects of losartan in EAC mice. METHODS: The inhibitory rates of t umor growth and the ratio of extending viability were observed in EAC mice in th ree groups given losartan, 5-FU and NS, respectively. RESULTS: Comparing with the control groups, the inhibition to tumor growth was 46.3 % in losartan ( 12.5 mg·kg -1 ) group. But losartan did not lengthen life time in EAC mice. The inhibition to tumor growth was was 31.5 % in 5-F U (5 mg·kg -1 ) group. CONCLUSION: Losartan can inhibit the tumor growth of EAC, but not lengthen life time of the animals.
