the results of quantitative experiments using colloidal gold particles indicated : 1 ) the upper size limit of colloidal particles absorbed by the large intestine , under the influence of mm was approximately 40 nm , 2 ) colloidal gold particles were transported from the intestine selectively into the lymphatics and accumulated in the regional lymph nodes , 3 ) the absorption of colloidal gold particles was largely promoted by mm in the rectum area .
