[Structural organization of the microcirculatory bed of the pancreas of the domestic cat].

In 35 cats by means of methods for the blood bed injection and revealing the pancreatic islets after K. Kramlinger, R. Mayrand and N. Lifson (1979) with an additional pikrofucsin staining, the microcirculatory bed of the pancreatic lobe has been studied at light and electron microscopic level. It is presented as arterioles, precapillary arterioles, capillaries of the pancreatic islets and the exocrinic part of the gland, postcapillary venules and venules. The precapillary arterioles always branch into capillaries within the limits of the pancreatic islets. Position of the pancreatic islets, structure of the capillaries surrounding the acini, that of the postcapillaries and connected with them pericapillary and intercellular spaces make it possible for hormones of the endocrinic cells to produce local (paracrinic) effects on the cellular elements of the pancreas.
