title: [Influence of physical loading on the content of intestinal microflora endotoxin in blood plasma and immunity indices to endotoxin].
abstract: The content of endotoxin of Gram-negative bacteria and humoral and granulocytic immunity indices to endotoxin in sportsmen and untrained persons before and after undergoing physical load were studied. The study revealed that prior to physical load the content of intestinal microflora endotoxin in the blood stream of volunteer students increased and the humoral immunity indices to endotoxin decreased. Judging by the content of cortisol in the blood, the state of stress increased after a physical load. In the groups with good adaptation a decreased endotoxin content in the blood stream was noted, especially 24 hours after load. On the contrary, in the groups with dysadaptation the content of endotoxin in blood plasma increased after a load and was accompanied by a decrease in antibody titers and in the reserve of leukocytes capable of binding endotoxin.
