  Background and objectives: The role of opioids on tumor growth is widely discussed. The aim of this study was to analyze whether morphine has a direct influence on tumor growth. Methods: Twenty mice received intraperitoneal inoculation of Ehrlich tumor cells and were divided into two groups. Morphine group received 10 mg/kg, and the control group received 0.9% saline solution, once daily for 7 days, by gavage of 10 ml/kg. On the tenth day, 5 animals were sacrificed, and 5 were evaluated for survival in each group. The following were evaluated: survival; abdominal circumference; ascites volume; weight; tumor cells in ascites; lymphocytes in the spleen, inguinal and mesenteric lymph nodes and bone marrow; cytokines in ascites, serum, lymph nodes and spleen; nitric oxide (NO) in ascites and spleen; nitrite in ascites; arginase in ascites; superoxide dismutase (SOD) in ascites; and immuno..
