Lymph capillaries: are they able to communicate directly with the interstitial canals?

The goal of this paper is obtaining data on the structural arrangement of the initial lymph capillaries. The object of this investigation is the small intestine wall of mature outbred dogs (n=5). The research method consists in staining 5-7 um thick paraffin sections with haematoxylin and eosin, with pararosaniline and toluidine blue. This method allows to eliminate the artefacts that might occur during the intravessel impregnation and interstitial stain injection. Results. Among smooth muscle cells some lymph capillaries have been found whose shape and diameter stand in marked contrast to conventional blind-ended capillaries.
