[The changes in mucus components of intestine after burn and their relationship with bacterial translocation]

A dynamic observation at 0.5 hr, 1 hr, 6 hr, 12 hr and 24 hr after 25% third degree burn in 363 rats: 1) The lesions of mucous membrane of ileum. 2) Assessment of the depth of mucus layer and the contents of protein, hexose and sialic acid. 3) Estimation of the content of mucus IgA, serum IgA and the number of plasma cell producing IgA in mucous membrane. 4) Bacterial culture of mesentery lymph node. The following results were achieved: 1) Serious lesions were discovered in ileal mucous membrane. 2) Mucus IgA content was reduced markedly and the reduction was related to bacterial translocation.
