“…The carotid body arteries are provided with marked intra-arterial endothelial cushions at their origins, probably inhibiting the retrograde flow of arterial blood (TAGUCHI et al, 1992) or regulating the inflow of arterial blood into the carotid bodies (McDoNALD and LARUE, 1983). LIFSON and LASSA (1981) injected silicone latex, India ink, hematoxylin and microsphere into the rabbit pancreas, and reported that the periductal plexus received blood from the lobular plexus. In our rat samples, as in the previously studied human samples (MURAKAMI et al, 1992), few channels were reproduced between the capillary plexuses of the exocrine lobules and the extralobular ducts.…”

“…It is evident, therefore, that the hormone content of such blood will exert its action either on duct cells or on endocrine cells associated with the ducts (buds and single scattered cells). Few studies on ductular blood supply have been carried out (Lifson and Lassa 1981;Ohtani et al 1983Ohtani et al ,1986Ohtani and Wang 1997). Pancreatic ducts have been reported to receive blood from a direct arterial supply and from connections with the acinar capillary network (Lifson and Lassa 1981;Ohtani et al 1983).…”

S U M M A R YTraditional histological descriptions of the pancreas distinguish between the exocrine and the endocrine pancreas, as if they were two functionally distinct glands. This view has been proven incorrect and can be considered obsolete. Interactions between acinar and islet tissues have been well established through numerous studies that reveal the existence of anatomical and functional relationships between these compartments of the gland. Less attention, however, has traditionally been paid to the relationships occurring between the endocrine pancreas and the ductal system. Associations between islet tissue and ducts are considered by most researchers as only a transient epiphenomenon of endocrine development. This article reviews the evidence that has emerged in the last 10 years demonstrating the existence of stable, close, and systematic relationships between these two pancreatic compartments. Functional and pathophysiological implications are considered, and the existence of an "acinar-duct-islet" axis is put forward. The pancreas appears at present to be an integrated organ composed of three functionally related components of well-orchestrated endocrine and exocrine physiological responses.

“…Within the lobule, in contrast, the exocrine acini and their connecting intercalated and intralobular secretory ducts are commonly supplied. LIFSON and LASSA (1981) arterially injected silicone latex, India ink, hematoxylin or microsphere into rabbit pancreas and traced it under the light microscope. Noticing that the ductal plexus received blood from the exocrine acini, they conceived of the following route: islet capillaries-acinar (lobular) capillaries-ductal plexuses.…”

Summary. Microdissection and scanning electron microscopy of corrosion casts showed the structures of the vascular bed of the human pancreas to consist mainly of the capillary plexuses of the exocrine lobules, extralobular ducts and endocrine islets.A considerable number of the exocrine lobules were found to contain one to four marked endocrine islets larger than 30um in diameter. These intralobular islets received one or more arterioles (afferent vessels) and emitted conspicuous insulo-acinar portal vessels which continued into the lobular capillaries, suggesting insular control over the functions of the exocrine acini of the pancreas. Direct drainage of the intralobular islets into the veins was never reproduced. Not excluding the possibility that some lobules might contain smaller, unidentifiable islets, there nonetheless were many lobules which directly received arterioles. These lobules are free of control by an islet.Rarely, an islet was located in the interlobular tissue space or along an extralobular duct. Such an extralobular islet issued no portal vessels, and drained into the interlobular or periductal veins. The surface of this type of islet comprised a thin network of fine capillaries. A possibility was suggested that this cortical network might be homologous with the lobular capillaries. No portal route was observed between the islets and extralobular ducts. Few connections were noted between the capillary plexuses of the lobules and ducts.
