The purpose of this study is to determine the effect of the two minerals zinc , and selenium the histological structure of intestine. thirty guinea pigs were divided in to five Groups(6 animals for each Group).the 1st group (S1) supplied with a selenium (0.02 milligram) ,the 2nd group(S2) supplied with (0.04 milligram). 3rd group (Zn1) supplied with a zinc (0.08 milligram), while the 4th group (Zn2) supplied with (0.16 milligram).the last group served as a control group received distill water instead. (Animals were treated daily with these minerals using stomach tube for two months). Infiltration of lymphocytes and phagocytes in particular polymorphonuclear cells (PMNs) was noticed in ileum sections. Dilation of blood vessels was seen in all treated groups. Presence of some spherical unidentified bodies with out nucleus was also detected. Epithelial cells were hypertrophied. As a conclusion, it was seen that zinc and selenium affect cellular and humeral immunity positively or negatively depending on the dose given. The ultra structure of certain organs was dearly affected.
