Popis:	X-ray fluorescence elemental analysis (XRF) involving synchrotron radiation (generated by the VEPP-3 storage ring) was used to study the characteristic features of the resorption and transport of lymphotropic X-ray-contrasting agents (XCA) - colloidal gold and thorium from the pericardial cavity - and the topography and morphological structure of mediastinum lymph nodes in intact animals and in animals with aseptic exopericarditis. XRF spectra of the lymph nodes, removed from the animals 1–20 h after tracer injection, were made. The quantitative treatment of the spectra was performed by external standards method. The adapting and compensating abilities of the lymphatic system are demonstrated by the XCA accumulation dynamics obtained for intact animals and for those with aseptic exopericarditis. The transport ability of the lymphatic system is shown to increase after XCA injection and to decrease with time.
