Background:
Sunflower seed oil (SSO) effect on solid and ascitic forms of Ehrlich tumor was evaluated.
Methods:
Solid or ascitic Ehrlich tumor-bearing Swiss mice were treated daily, by subcutaneous route, with 200 microl of SSO. The solid tumor-bearing footpad was measured every 3 days and ascitic tumor-bearing mice had their ascites collected and quantified. At the end of the SSO treatment, the total cell number in lymphoid organs was quantified.
Results:
Subcutaneous treatment with SSO inhibits the solid tumor growth and increases lymph node cell number in animals with solid tumor, but has no effect on animals with ascitic tumor.
Conclusions:
SSO can delay the solid tumor growth, possibly due to better absorption of this treatment by draining lymph nodes.
