/kg). Diabetes was induced by pre-treatment with streptozocin. Biochemical parameters measured were production of IL-2, TNF-α, VEGF, tumor weight, tumor inhibition rate, blood insulin level, total cholesterol, triglycerides, serum HDL and LDL, activity of CAT, SOD, and GSH, content of MDA in liver, heart, pancreas, and kidneys, and finally blood content of alkaline phosphatase, AST, ALT, total bilirubin, creatinine, and urea. Treatment with the Se-P was shown to largely decrease the release of IL-2, increase TNF-α, and to decrease the production of VEGF 1.5- to 3.5-fold better than treatment with 5-fluorouracile used as control. Furthermore, administration of the Se-P at doses of 100 and

Weights and functionalities of target organs listed above remained unaffected upon feeding with Se-P and no lethal effects were observed in animals during the whole duration of the test. Lipids serum concentrations were all diminished after the administration of the Se-P being total cholesterol, triglycerides, HDL, and LDL values 5.8 mmol/L, 3.1 mmol/L, 3.6 mmol/L, and 0.6 mmol/L respectively for streptozocin treated animals and 2.8 mmol/L, 0.9 mmol/L, 0.9 mmol/L, and 1.7 mmol/L for animals fed with the Se-P. The last set of values were practically the same of animals treated only with the vehicle. A marked decrease of MDA concentration and a huge increase of the activities of CAT, SOD, and GSH were also recorded in all target organs. Finally, blood insulin remained unchanged in the Se-P treated group of animals respect to untreated controls.
